6kW Air Conditioners

R32 refrigerant is a Hydrochlorofluorocarbon (HFC) refrigerant and is used as a replacement for R410A in low temperature refrigeration and air conditioning applications. R32 cannot be used as a retrofit refrigerant.

R22 is a Hydrochlorofluorocarbon (HCFC) refrigerant used in air conditioners, process chillers and industrial plant cooling systems. R22 is an ozone depleting gas and EU legislation banned its stockholding and system topping up from 1st January 2016. As a result air conditioners using this refrigerant cannot be maintained and must be replaced.

Liquid immersion cooling is a cooling solution for high-density racks in server rooms (40-50kW) and datacentres that relies on heat reduction through the immersion of the server hardware in a dielectric liquid that can conduct the heat. A dielectric liquid for this type of cooling application should have good thermo-physical properties (high conductivity and specific heat), low freezing and burst points, a high atmospheric boiling point, good chemical and thermal stability, high flash and auto-ignition points, be non-corrosive to materials including metals and plastics, have no or minimal regulatory constraints and be economically viable as an alternative to air-based and gas refrigerants.
