All You Need to Know About Refrigerants: Types, Application, Freon Addition
Cooling systems require a special substance - refrigerant or freon. There are several types of them, and each has its characteristics. A + Refrigeration Heating & Air Conditioning provides services to fulfill your AC with a suitable option.
What is Refrigerant and Its Different Types?
HVAC freon is the technical name for a group of chemical compounds based on methane or ethane. These gases are harmless to humans, but they deplete the ozone layer. According to their environmental safety, air conditioner freons are classified into three types:
- Chlorofluorocarbons (CFCs) - a very high ozone depletion potential: R-12 refrigerant (R-12 freon) and R-22 (R22 freon). They are prohibited.
- Hydrochlorofluorocarbons (HCFCs) - less harmful to the ozone layer. These are R-410A and R-407C refrigerants.
- Hydrofluorocarbons (HFCs) - no threat to the ozone layer. These freons are R-134A refrigerant (A/C PRO R-134A), R-404A, and 421A refrigerant.
There are over 50 freons and mixtures that are used for refrigerant air conditioning. People prefer to buy freons with natural refrigerants: like ammonia, hydrocarbons (propane and butane): R32, R290, and R600A refrigerants. They are eco-friendly and have low energy consumption.
Note! There is a freon that does not require replacement refrigerant oil: MO99 or (R-438A). It is suitable for split systems.
How to Add Refrigerant to Home AC or Refrigerator?
It is imperative to choose the suitable substance of freon AC. Otherwise, the device will quickly break down. Entrust this process of changing the liquid refrigerant to professionals. Failure of the procedure can cause malfunction of the AC or refrigerator and become hazardous to the environment.
