End-to-end service for Refrigerant Gas in Madurai
A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated due to their toxicity, flammability and the contribution of CFC and HCFC refrigerants to ozone depletion and that of HFC refrigerants to climate change.
Refrigerants are used in a Direct Expansion (DX) system to transfer energy from one environment to another, typically from inside a building to outside (or vice versa) commonly known as an “air conditioner” or “heat pump”. Refrigerants can carry per kg 10 times more energy than water and 50 times more than air.
Refrigerants are controlled substances due to
1) High Pressures (100-145 psi)
2) Extreme temperatures (-50°C to 145°C)
3) Toxicity B1-low, B2-medium & B3-high, as classified by ISO 817 & ASHRAE 34.
Refrigerants may be divided into three classes according to their manner of absorption or extraction of heat from the substances to be refrigerated.
Class 1: This class includes refrigerants that cool by phase change (typically boiling), using the refrigerant’s latent heat.
Class 2: These refrigerants cool by temperature change or ‘sensible heat’, the quantity of heat being the specific heat capacity x the temperature change. They are air, calcium chloride brine, sodium chloride brine, alcohol, and similar nonfreezing solutions. The purpose of Class 2 refrigerants is to receive a reduction of temperature from Class 1 refrigerants and convey this lower temperature to the area to be cooled.
Class 3: This group consists of solutions that contain absorbed vapors of liquefiable agents or refrigerating media. These solutions function by nature of their ability to carry liquefiable vapors, which produce a cooling effect by the absorption of their heat of solution. They can also be classified into many categories.
Refrigerant reclamation by certified
Refrigerant reclamation is the act of processing used refrigerant gas which has previously been used in some type of refrigeration loop such that it meets specifications for new refrigerant gas. In the United States, the Clean Air Act of 1990 requires that used refrigerant be processed by a certified reclaimer, which must be licensed by the United States Environmental Protection Agency (EPA), and the material must be recovered and delivered to the reclaimer by EPA-certified technicians.
