Hvac Refrigerant Types

It is an hfc refrigerant as well.

Hvac refrigerant types.

This is a list of refrigerants sorted by their ashrae designated numbers commonly known as r numbers. A blend of two hydrofluorocarbon refrigerants difluoromethane and pentafluoroethane r 410a is a non ozone depleting refrigerant that provides better energy efficiency than both r 22 and r 407c and uses no chlorine in its makeup. The classification of refrigerants into different groups is due to their chemical composition. They will most likely all be replaced by new hfo refrigerant equivalents.

Many modern refrigerants are man made halogenated gases especially fluorinated gases and chlorinated gases that are frequently referred to as freon a registered trademark of chemours. R 410a is a type of hfc refrigerant that is widely used in newer ac units replacing older hcfc coolants. It is important to note that hfc refrigerant such as r134a r410a and r404a are being slowly phased out due to their high global warming potential. R 22 no this is not r2 d2 from star wars but refrigerant type r 22.

Low medium l m and medium high m h pressure. Refrigerants are the key ingredient to the air conditioning soup. R 22 is an cfc refrigerant. You might know this refrigerant as freon.

R 404a is primarily used transport refrigeration. The flammability penalty is very low and manageable especially for systems installed. One thing a hvac specifier or purchaser can do for the environment regardless of the refrigerant used is to select a reputable dealer that employs epa certified technicians to use refrigerants. R 410a is a mixture of two other hfc refrigerants r 125 and r 32 and offers greater cooling properties than older hcfc refrigerants when they are subjected to higher pressures.

L m pressure chillers can benefit from the use of pure hfos r1233zd and r1234ze resulting in a gwp close to zero. For example residential hvac chillers often use ammonia as the refrigerant and water as the absorbent. The most common refrigerants include chlorofluorocarbons cfcs hydrochlorofluorocarbons hcfcs hydrofluorocarbons hfcs and natural refrigerants. Unlike mechanical compression refrigeration systems which typically use r 22 and r 410a for refrigerants absorption refrigeration systems use refrigerants that other substances are attracted to and absorb.

Different types of refrigerants in hvac. They make air conditioning possible.
