csc 11Air conditioning manufacturer Carrier has introduced a high-speed screw compressor that has been tested with a new low pressure, non-flammable HFO refrigerant Air conditioning manufacturer

This aims to address the global shift towards refrigerants with low global warming potential (GWP).

In a research paper, Carrier engineers Masao Akei, Vishnu Sishtla and Scott MacBain said that addressing global warming concerns is one of the largest challenges facing the HVAC industry. Although A2L refrigerants are important options to consider for certain sizes of HVAC units, there are many systems that require A1 category refrigerants.

The refrigerant R32, in addition with Honeywell’s R466A, aims to provide a lower GWP option. Carrier’s newly-developed prototype screw compressor employs a new rotor design and a high-speed permanent magnet motor to obtain a flow volume of 19.8 litres per second.
