Heavy! Danfoss announces full certification of R32 components

Heavy! Danfoss announces full certification of R32 components In response to the global trend of accelerating the conversion of low-GWP refrigerants, considering safety, environmental protection characteristics, cost performance and energy efficiency, Danfoss has now launched a full range of system solutions optimized for R32 refrigerants. R32 refrigerant has a relatively low GWP (Global Warming Potential) of 675, strong refrigeration capacity, high efficiency, low price and small charge volume. It is proved to be the same as R454B and R452B, replacing R410A in air conditioning and heat pump applications. One of the best choices for refrigerants. In view of this, Danfoss specially introduced special components for R32 refrigerant system to help air-conditioning equipment manufacturers shorten the system development time and speed up the time to market. In order to meet the increasing demand for energy-saving and environmentally friendly products in the market, Danfoss has launched new R454B, R452B, R32 new environmentally friendly refrigerant products. At present, R32 refrigerant components can meet the demand of the maximum cooling capacity of 700kW/260TR. Danfoss series products with R32 refrigerant DSF fixed speed scroll compressor (with IDV) based on R32 application optimization design-a full range of products can be provided by the end of 2020 Miniature plate heat exchanger based on R32 application optimization design (MPHE/Z series)-A full range of products can be provided by the end of 2020 Full range of MCHE microchannel heat exchangers DCRE filter for flammable gases ETS Colibri? electronic expansion valve System protector and piping components, such as NRV check valve, GBC ball valve, EVR v2 solenoid valve, ACB pressure switch and DST P110 sensor, DML and DCL filter drier, SG sight glass, etc. Experience has proved that the raw materials have good compatibility. In addition, valves with a joint of more than 25mm have passed PED II certification, while EVR v2 solenoid valves have passed US verification. It is worth mentioning that the design of the Danfoss scroll compressor can help equipment manufacturers to make full use of the thermodynamic characteristics of R32. Compared with the same type of compressor, its cooling capacity is increased by 10%, which reduces the customer’s cooling capacity per unit. cost. Since the temperature of the exhaust gas can be lowered without the need for expensive liquid sprays or jets, a wide operating range is ensured-suitable for cold (hot) water units, so this design has a significant cost-effective advantage. Like Danfoss DSH series air-conditioning scroll compressors, DSF series scroll compression also uses intermediate exhaust valve (IDV) technology to meet the needs of seasonal energy efficiency. It is the best choice for commercial chillers and rooftop machines. Mr. Matthieu Stoll, Director of Air Conditioning Marketing, Danfoss Refrigeration, said: “Globally, air conditioner OEMs are phasing out R410A. Danfoss adds new R32 series products to the existing multi-refrigerant R410A / R452B / R454B product portfolio, We are committed to providing our customers with the widest selection."
