SRS Frigadon Ltd has partnered with its sister company, Frigadon AB to develop and produce the new FWC3000HC. This embodies the next generation in natural refrigerant chillers adding to its excellent range of water chillers. The characteristics of these units include the ability to reach 320kW medium temperature and 450kW for A/C equipment.

This new range of chillers features an increase in capacity with advanced technology that provides energy savings borne out of 14 years of technical expertise in hydrocarbon refrigerant development.

Coupled with the reputable Scandinavian commitment to environmental preservation, the FWC3000 makes use of modern components that include Ziehl-Abegg inverter driven condenser fans; Grundfos stainless steel inverter pumps and top line components and compressors from Bitzer.

Minimized power input is derived from Frigadon’s Pump Energy Optimisation mechanism that prevents power wastage by matching internal flow conditions to the pump inverter. Conversely, increased COPs are gained from the use of the R1270 principal natural refrigerant. An additional option is the utilization of the heat from the process of refrigeration that provides a heating system that can be used to warm water or provide heating for the floor.

These new energy saving innovations are designed to be easily incorporated into the current range of chillers to match the offerings of the FWC3000 making them more economical and efficient to use in scaled down settings.

According to the Managing Director of SRS Frigadon, Alan Colbourne, these chillers have been built with the latest advancements in technology as well as skills and hopes that their introduction into the world market will mark the beginning of a new era in environmental preservation. He states that a new range of liquid cooled chillers at the design and development stage will use Bitzer screw compressors which are hydrocarbon based thus, providing the opportunity to focus on larger projects in the future.

A number of benefits are attributed to hydrocarbons including their use in semi-hermetic and hermetic compressors as well as compatibility with common lubricants and materials in addition to favorable thermodynamic properties. As such, the use of chlorine-free refrigerants can be substituted by HCs as long as the necessary safety measures are put in place to handle their flammability.

R290 Properties

R290 has the following characteristics:

• Highly soluble with ester oils and common lubricants.
• Avoidance of Magnesium and Zinc with over 2% content.
• Adherence of safety standards by keeping the range of flammability between 1.7 and 10.9% by volume in air.
• Avoidable Exposure Limit (AEL), should not exceed 1000 ppm
• Insignificant effect on Global Warming at GWP=3 and nil potential for Ozone layer depletion.

Handling high solubility properties of HC refrigerants in oil lubricant

Due to the low suction pressure and low temperatures of lubricant, there may be a reduction of viscosity in the oil despite the high solubility of the hydrocarbon refrigerants.

This points to the fact that higher viscosity based oils are suitable such as Polialfaolifina (PAO) (SHC226E) for medium and low temperature cooling capacity due to its matching viscosity, reduced vapor pressure and lower rate of solubility. For A/C use, higher viscosity-based oils are the preferred choice like VG 68.

Set up and maintenance

The following principles are to be followed in set up and maintenance:

Replacement of oil has to be done under lower pressures and with warmed oil followed by flushing with nitrogen.

The replacement of an old filter and cleaning is to be carried out before recharging. As long as there is no static gas or other pollutants in the system, the R290 can be removed and reinstalled.

Annual inspection of all devices is a must.

Safety warnings must be printed on the compressor and system.

The maximum refrigerant loads of the R22 and R502 are higher than that of the R290 because of the lower density of liquid it uses.

The compressor must be placed in an isolated location when being tested with dry air and the service valve must be closed. Dry nitrogen is recommended for high-pressure tests and leaks.

R290 expansion valves must be customized

Dry nitrogen should be used as a shielding during welding.

Welding must be applied to connections and tubing.

It is essential for operators and technicians to work in a room where ventilation has been turned on.

• The machine room ventilation must be turned on whilst technicians and operators are working in said room;
• Tubing and connections should be welded;
• Welding must be performed with a shielding gas (dry nitrogen);
• Expansion valves must be specifically designed for R290;
• To test for leaks and for high-pressure tests, the use of dry nitrogen is recommended. If dry air is used for the test, the compressor must be isolated during this procedure (the service valve must be closed);
• Due to the low density of liquid R290, the maximum refrigerant load is lower than that of R22 and R502. The maximum load (95% at 50°C) for 1 dm³ volume is: R290 → 0.43 kg compares to R22 / R502 → 1.03 kg;
• The system and the compressor must be labelled with the safety warnings;
• Regular inspection of safety devices (at least once a year) is essential
• During maintenance the R290 can be removed and used again, provided that no inert gas or other contaminants are present in the system. Prior to recharging, the system must be purged with nitrogen and should a new filter drier installed;
• Oil changes must only be performed with warmed oil and reduced pressures, followed by purging with nitrogen.

Frascold’s R290 semi-hermetic compressors have finally been introduced to the Danish market. The system was built for indirect cooling and consists of an air-cooled condenser as well as air-cooled water chillers that come with a plate h

eat exchanger of the R290 specification. Ethylenglycol (30%) has been used for the second side. The system has been provided by Bundgaard Køleteknik A/S, a local producer of R290 Propane air and water-cooled liq

uid chillers.

Specifications and General Requirements

13 independent units in the rooms and the common areas of the center required a cooling system that was sustainable and highly effective. Engineers had to contend with a total surface area of approximately 4,450 square meters.

Installation of the system included a brazed plate heat exchanger for the ventilation unit as well as a distribution pump feeding the ceiling cassettes by 4-ways air circulation and reservoir including a hydrostation.

Minimal operation of the chiller would take place as a result of the ventilation unit coupled with brazed plate heat exchangers to cool air intake as regularly as possible.

Effortless interaction with the ventilation system is made possible by the use of a CTS system used for cooling purposes.

The rationale behind using R290 as the refrigerant

R290 is a hydrocarbon that occurs in a natural form and is a well tested refrigerant solution. It is suitable for utilization on cold climates and literally harmless to the environment while being a highly cost effective alternative to carbon dioxide and ammonia.

Frascold’s rich background with Hydrocarbons

Frascold’s compressor production exceeds 70,000 units annually. The Italian manufacturer is a major promoter of hydrocarbons in residential refrigeration and air conditioning, having developed a new line of semi-hermetic compressors for use as natural refrigerants and are identified through the AXH suffix. Modifications have been carried out in compliance with safety standards for hydrocarbons and flammability and are thus compatible with the most frequently used hydrocarbons which are isobutane R600a, propylene R1270 and propane R290.

Who are Frascold?

Frascold is an Italian company with over 70 years of experience in the industry manufacturing applications and components for air conditioning and refrigeration. It has a worldwide sales network.

The 2013 China Refrigeration Expo Highlights Hydrocarbon Product Developments

Dubbed as the premier event for HVAC&R products in the Asia-Pacific region, the 2013 China Refrigeration Exhibition was held at Shanghai, from 8 to 10 April, 2013. The latest products and technologies were displayed by 1146 exhibitors from all over the world. In China, market leaders and suppliers are advancing their products and technologies to remain competitive in the hydrocarbon product field. Many of them have acknowledged that hydrocarbon based refrigerants have become the product of choice with great market opportunities available for air conditioners and domestic refrigerators.

Some of the leading manufacturers who participated in the Expo include the following:

Castel

Successful Journey of Greenfreeze with Hydrocarbon Refrigerants

Greenfreeze technology uses natural hydrocarbon refrigerants that do not contribute to ozone depletion causing climate change in place of the now obsolete ozone-depleting CFC’s and HCFC’s. Oz-Chill, an Australian owned company is at the forefront in enhancing the benefits of this technology to consumers by providing energy efficient, environmentally friendly and safe refrigerant gas. It offers retrofitting solutions for vehicle, residential and commercial air conditioning including refrigeration and mining.

The introduction of Carbon Tax by the Australian Government in July 2012 has led to the increase in production costs for many businesses and individuals but, as Oz-Chill continues to make a major contribution to the reduction and elimination of the carbon footprint altogether, consumers are able to gain relief by making use of their products and services. Needless to say, leading brands have adopted the use of Greenfreeze technology in the last two decades including Oz-Chill, with a largely positive effect.

Manufacturers are now using hydrocarbon refrigerants as a result of the ban on CFC production occasioned by the Montreal Protocol in 1997. Prior to this, the first commercially viable Greenfreeze hydrocarbon fridge for domestic use was manufactured in 1993. Up to date, approximately 35 million refrigerators using Greenfreeze technology have been produced accounting for 40% of global production on a yearly basis.

The key producers are European, Chinese, Japanese and Indian. This has had a major bearing on the Australian Government Environmental policies spurring the growth of industries that strive to produce refrigerant gas under stringent quality measures while setting the standard for environmental preservation. This is derived from Hydrocarbon Propane a naturally occurring and pollutant free gas. Oz-Chill provides different blends that are manufactured from pharmaceutical grade Hydrocarbons which cater for varying purposes all with the objective of ensuring a reduction in carbon emissions.

Oz-Chill refrigerants contain hydrocarbon of the highest quality which guarantee lower energy consumption and maintenance costs because of the use of Greenfreeze technology that allows for a reduction in lower operating discharge pressures.

Hydrocarbon Refrigerants play a key role in minimizing carbon emissions because they require only between 30% and 50% of refrigerant volume while reaching higher temperatures quicker. Temperatures of over 40 °C do not present any challenges to the performance of this refrigerant. Retrofitting this system is simple and straight forward as Oz-Chill is engaged in Hydrocarbon training programs that ensure staff are qualified to install the system. This provides a savings of between 10% and 40% in power consumption.

Hydrocarbon refrigerants are able to operate at optimum levels without causing any significant or adverse effects to the environment.

This past March 2013, the Consumer Goods Forum (CGF) released guidelines around the strategic Sustainability initiative with the new Activation Toolkit. Refrigerant gas has been identified as a major area of opportunity; especially the reduction or elimination of Hydro Fluorocarbon (HFC) based refrigerants. In sharing best practices, hydrocarbon refrigerants are a great alternative for saving energy costs and reducing the environmental impact of manufacturing operations.

While replacing HCF based refrigeration systems with a much cleaner and cheaper alternative, such as R290 refrigerant can seem like a huge undertaking. With a bit of research, it is possible to find companies who offer hydrocarbon refrigerants that can be easily switched in your existing systems. OZ-Chill is one such company; it offers you OZ-Chill Refrigerants. The CGF Activation Toolkit also shares best practices and case studies from across the world.

Coca-Cola Enterprises is one such case. The CGF, which consists of 400 global consumer goods manufacturers, announced plans to phase out HFC refrigerants and replace them with natural refrigerants, such as hydrocarbon refrigerants, as of 2015, depending on local country regulation. Two years ahead of schedule, Coca-Cola Enterprises has already phased out the purchases of HFC-based refrigeration equipment. They are also working on switching the rest of their operations to HFC-free based systems.

For smaller manufacturers, these best practices are not just good for the environment or ensure timely compliance with governmental regulations. They are good for the bottom line. OZ-Chill refrigerants can offer substantial savings on electricity consumption costs. Switching from the most common HFC chemical refrigerant gas to hydrocarbon refrigerants can save also on costs related to renting bottles and managing the inventory of these bottles to schedule returns or ensure you receive your deposits back. The bigger your operation is, the higher your potential cost savings.

The CGF guidelines are just that – guidelines meant to help the industry manage and share best practices around strategic and trending priorities. These are not mandated by law. As the environment becomes a bigger issue internationally, your customers may even start to require compliance with such industry-wide measures.

Even if your company is not a member of the Consumer Goods Forum, adopting these guidelines can help you take advantage of the work and knowledge of some of the biggest global brands. In the March 2013 Activation Toolkit, refrigeration is identified as a key area to target. Switching to hydrocarbon refrigerants can save you money, help you comply with these guidelines and ultimately ensure that your company is a responsible member of society.

As part of the Australian Government’s Clean Energy Future Plan, the equivalent carbon price for synthetic greenhouse gases commenced on 1 July 2012. The introduction of the equivalent carbon price encourages industry to change their practices in order to reduce emissions of synthetic greenhouse gases, to use alternative gases and to improve the recycling rates of these gases.

Pioneer International Pty Ltd (Pioneer) manufactures a range of cassette and ducted split air-conditioning systems that use a natural hydrocarbon refrigerant. The hydrocarbon models were introduced in mid-2012 as a direct response to the introduction of the equivalent carbon price.

Pioneer have since chosen to work with Oz-Chill’s hydrocarbon refrigerants due to their energy efficiency, environmental impact and quality of production.  After completing their research and development, Pioneer were encouraged by the results and have decided to continue using Oz-Chill’s hydrocarbon refrigerants in their Hydrocarbon Range of systems.

The refrigerant’s used by Pioneer are Oz-Chills Multi and 22a, which are blends of alkanes formulated to operate at lower pressures compared to R-410a (a commonly used hydrofluorocarbon refrigerant). The lower operating pressure enables the compressor to be operated at a reduced loading, which reduces energy consumption, heat and stress upon pipework joints and equipment components.

Pioneer estimates that its hydrocarbon models are approximately 10% less expensive compared to its hydrofluorocarbon equivalents. Of greater value, however, is the environmental benefit as the high global warming potential of 1,725 of R-410a can be reduced to a global warming potential of 3 with Oz-Chills hydrocarbon refrigerant.

To ensure safety, Pioneer’s air-conditioning equipment is designed and tested to operate in accordance with Australian Standards. Pioneer also requires its dealers to be registered with the Australian Refrigeration Council Ltd’s ArcTick licensing scheme, and trained in the use of hydrocarbons.

The changes effected by Pioneer provide it with environmental, technical and operational advantages:

• The use of a lower global warming potential gas helps to minimise the environmental impact.

• The reduced wear and tear due to the lower operating pressures will provide Pioneer and its customers with increased equipment life; and

• Pioneer’s early adoption of hydrocarbon technology will ensure that it is at the forefront of the industry and able to deliver a second generation product when its competitors are only entering the market with a first generation product.

Applying an equivalent carbon price to synthetic greenhouse gases creates an incentive to implement changes to reduce emissions. As seen from this case study, the changes implemented can increase opportunities as well as provide ongoing financial and environmental benefits.

The post Pioneer International Develops Natural Refrigerant Air-Conditioner Range appeared first on Oz-Chill - Hydrocarbon Refrigerants.

The Aarhus University Hospital Skejby in Denmark has been replacing out of date R22 chillers with new hydrocarbon chillers.  Most recently hydrocarbon heat pumps supplied by Johnson Controls have been installed.

The first hydrocarbon chillers were already installed in 2003 and as the hospital has been gradually expanded additional hydrocarbon chillers have been installed.

The larger chiller system:

• Uses 9 air-cooled propane (R-290) based chillers each with a cooling capacity of 250 kW, coefficient of performance (COP) of 4.5 and a total of about 210 kg R290
• Uses a free-cooler with a capacity of 300 kW
• The chillers deliver a 35% propylene glycol/ water solution at 9°C and return at 15°C

On top of the 9 chillers there are also some special chillers around on the site working at different temperature levels, bringing the total number of hydrocarbon chillers on site to 15.

Moreover the latest installation made in the context of the gradual expansion encompassed two heat pumps that were put into operation in November 2010, with:

• Hydrocarbon refrigerant isobutane (R600a) of a total of about 80 kg
• A total heating capacity of about 450 kW and a cooling capacity of about 325 kW
• The units are built as two independent circuits on one frame

Experience with the R600a heat pumps so far and lessons learnt

The primary function of the heat pumps is to deliver cold water. The engaged capacity is therefore given by the cooling requirement. On the warm side, the flow is controlled to keep up the condensing temperature and the pressure in the local district heating system.

The values that were assumped at the beginning of the project are consistent with what has been measured over the last 1½ year since the commissioning of the system.  In general, the experience with the heat pumps so far has been very good as they have not only met but also exceeded expectations.

An additional benefit for the University Hospital from installing the heat pumps is security of energy supply: the entire system is connected to a local generator set which ensures stable supply and independence from the local grid in case of a power blackout.

One important lesson learned was that compared to refrigeration systems, heat pump insulation needs more than normal consideration. The heat loss can be quite substantial and Johnson Controls has estimated it to be about 15 to 20%.

Combining heating and cooling

The new system combines the cooling system with the heating system, an approach that is still not widely used in most places in the world, despite the obvious intrinsic energy savings. However, due to increasing energy prices, customers have become more receptive to using new ways of thinking to save on their energy bills.

As a result, the new system offers better performance meaning energy savings, which also translates to CO₂emissions savings.

With the hospital normally obliged to take the required heat from the district-heating network, the project involved talks with the local district heating company. In the winter period, the supply temperature of water is 80°C and in the summer it is supplied at 70°C. The return is 40°C. This requires the heat pumps to deliver water at 80°C and at the same time cool water. During winter, there is also a cooling load, which the heat pumps will be able in part to deliver while the rest is managed by the free coolers. In the summer period, there is a base load for heating of tap water and room heating 400 to 500 kW provided by the heat pumps.

Safety aspects

Using hermetic design with no shaft seals or semi-welded heat exchangers, Johnson Controls has eliminated most flammability concerns of hydrocarbon refrigerant. For the units installed outdoor with a secondary loop an efficient micro bubble separator is included as a result of which no gas will ever reach inside and the possibility of getting a flammable concentration is not present. Moreover, in case of a leak, all power to the unit is cut out and can only be restarted manually from the panel (remote reset not possible).

Regulatory context: complying with international and national provisions

The project has been a success and the University Hospital has got a new system that complies with both international obligation under the Montreal Protocol that banned the use of HCFCs in new installations as of the year 2000, as well as Danish regulations which ban the use of HFC charges over 10 kg. At the same time, the hospital has avoided the high cost associated with HFC refrigerants, which is intensified by their heavy taxation introduced in Denmark in 2003.

Moreover, a number of R22 chillers have been taken out of service and 2,000 kg R22 (1,700 GWP) has been recycled.  This is equivalent to 3,400,000 kg’s of CO2 being removed.

Media Release: Refrigerants Australia scaremongering? All refrigerants have risks.

“These statements are wrong and misleading in the extreme.  Refrigerants Australia misrepresentation is being used for political point scoring. Refrigerants Australia is scare mongering to protect their commercial interests regardless of the facts,” said Australian Refrigeration Association President Mr Tim Edwards.

“Absurd allegations being made by Refrigerants Australia are just sour grapes, the relevant facts are:

“All refrigerants are dangerous and need to be handled with care.  All refrigeration technicians are aware of this fact.

“Refrigerants Australia is representing the commercial interests of their members regardless of the real implications of using fluorocarbon refrigerants. But the Materials Safety Data Sheets for fluorocarbon refrigerants state that they are dangerous and need to be handled with care, as do natural refrigerants,” Mr Edwards said.

“Safety is not the issue. All refrigerants can be handled and used safely.

“The issues are economic efficiency and environmental impact. Natural refrigerant based technologies are commercially and environmentally preferable.

“Natural refrigerants are extensively used in Australia and worldwide. There are 400 million domestic refrigerators in use worldwide based on hydrocarbon refrigerants but a vanishingly low level of safety incidents.

“Hydrocarbon refrigerants have been used in Australia for almost two decades for motor vehicle air conditioning with no on road incidents and only a small number of servicing incidents due to poor work practices.

“The Consumer Goods Forum, comprised of leading multinational food suppliers and retailers, endorses the use of natural refrigerants because they have been shown to be energy efficient, environmentally preferable and safe.

“Hydrocarbon refrigerants and all natural refrigerants are preferable because they are energy efficient, have extremely low or no direct climate impact and are therefore more cost effective to use. These benefits are important to Australia.

“The statements made by Refrigerants Australia and regrettably taken up by Greg Hunt reflect the commercial self-interest of the fluorocarbon industry. They do not reflect Australia’s economic or environmental interest.

“The Kyoto and Montreal protocols have been adopted by governments worldwide, and driven by the scientific community because there is a real need to phase out the use of fluorocarbon refrigerants. Australia’s decision to impose a carbon equivalent price on these most powerful global warming gases is the right thing to do for the environment, and by improving energy efficiency will also benefit consumers.”

In conclusion, Mr Edwards said “It is time for the HVAC&R industry to deal with the facts:

“1. The Australian government has passed legislation to encourage transition from fluorocarbon refrigerants to natural refrigerants.

“2. The Australian government has endorsed policies that call for the phase out of fluorocarbon refrigerants worldwide

“3. The HVAC&R industry needs to embrace the transition to natural refrigerants rather than scare mongering.

“4. There is a great deal of work to do to enable and promote the use of commercially and environmentally preferable HVAC&R technologies including development of standards, codes of practice, licensing and training in the use of natural refrigerants.”

“Finally, we all need to be aware there will be safety incidents in the HVAC&R industry. Whilst the level will be low there will be incidents if people fail to obey relevant standards and safe work practices. The nature of the HVAC&R is that refrigerants are fundamental and the industry must be licensed and trained to use all refrigerants safely.”
