NEWS MEHITS chooses Opteon refrigerants M
itsubishi Electric Hydronics and IT Cooling Systems (MEHITS), part of Mitsubishi Electric Group, has selected low global warming potential (GWP) Chemours refrigerants Opteon XL41 (R454B) for its multi- scroll platform and Opteon XP10 (R513A) for its screw and centrifugal oil free platform, produced in Europe.
This is part of an environmental initiative to provide effi cient, sustainable, and long-term solutions to the chiller market ahead of the next 2021 European F-Gas cap phase-down, and will be implemented this year. MEHITS selected Opteon XL41 (R454B), an A2L class refrigerant, because it off ers the lowest GWP replacement solution, at a GWP of only 466, for R410A.
Opteon XL41 also reduces CO2 emissions by almost 80 percent when compared to R410A, while providing improved energy effi ciency, similar capacity, and excellent design compatibility.
When compared to other alternative candidates for large fi xed speed units, chillers and heat pumps, the adoption of Opteon allows a smoother transition and the extensive operating envelope makes its use in heat pump application simpler to manage.
The selection of Opteon XL represents the commitment by both MEHITS and Chemours to support the safe and proper transition to A2L class refrigerants in Europe. Opteon XP10 (R513A) is a non-fl ammable A1 azeotropic refrigerant alternative to R134a with a GWP of only 631, making it an ideal replacement for MEHITS with a 50 percent lower GWP compared to R134a.
“We are proud that MEHITS chose Chemours and Opteon XL41 and XP10 for its chillers and heat pumps. This collaboration will help the chiller and heat pump industry move towards more environmentally sustainable refrigerant solutions while meeting long-term regulatory requirements and delivering consistent
performance,” said
Diego Boeri, vice president of Chemours Fluorochemicals.
Opteon low GWP HFO refrigerants are a portfolio of sustainable and versatile refrigerants that meet the long-term needs of the refrigeration, air conditioning, heat pump, and chiller markets.
They have been developed to address increasingly stringent global regulations while maintaining or improving performance compared to the products they replace, as well as encouraging more sustainable refrigerant choices and equipment designs to reduce the carbon footprint of the HVACR industry. Specifi cally, in Europe, the very low GWP Opteon XL refrigerant portfolio supports the market transitions required by the F-Gas Regulations and enables customers to select their optimal solutions, considering performance, safety, sustainability and total cost of ownership.
Changes at the top for FETA
T
he Federation of Environmental Trade Associations (FETA) has announced two changes to its senior officer roles.
Nick Howlett has stepped down as FETA chairman and is replaced by Mark Woods, currently president of the British Refrigeration Association (BRA). Mr Howlett remains as HEVAC president and he will be closely involved in the review and update of the Building Regulations, which is currently underway. Mr Woods is the owner and operator of contractor and industry consultancy RefMech, and was previously managing director of Space Engineering Services. Having started his career in 1986 as an apprentice at Carter
8 July 2019
Refrigeration, Mr Wood has held several technical and leadership roles in his 33 years in the industry, which include having been a member of the EURIS panel representing industry during the Brexit process, and also a panel member for the new T Level qualification in Refrigeration, which is due for launch in 2021. Meanwhile, the BRA has elected Mark Hughes as vice president. Mr Hughes works for Chemours as business development manager for Opteon refrigerants, and he is a well-known figure in the industry. He is also vice chairman of the BRA Equipment and Components division, and, like many FETA members, represents the BRA on a BSI standards committee.
Did you know? Humidifi er not
working…? ■ Is it switched on? Check the power supply and on/off switch. Consult the unit’s technical manual if you’re not familiar with the equipment.
■ What’s the actual humidity? If your humidity level is already at the required set point or higher the humidifi er will not be on. To test it, increase the humidity set point and check to make sure your humidifi er comes on. If it’s working correctly the humidity levels will start to rise.
■ Check for any status or fault messages. These will normally be shown on a display screen or by indicator lamps on the front of the unit. In most cases, error codes are displayed rather than text. Consult the unit’s technical manual for a detailed
explanation of error codes.
■ Check any external interlocks. If there is a fault or failure on another part of the system, the external interlocks will prevent the humidifi er from working as a safety precaution.
