What is refrigerant?

It is a fluid circulating to transport energy inside air conditioners, refrigerators, and heat pump hot water heaters. It is a very important substance which hits blood if it says in man. As a refrigerant, fluorocarbons (carbon and fluorine compounds) are used mainly, and it is generally referred to as fluorocarbons. Fluorocarbons were developed for … Read more

Types of refrigerant

In the table below, cfc, HCFC, and HFC-based fluorocarbons, typical refrigerants, are shown. There are various types of fluorocarbons in this series, and each refrigerant has a refrigerant number. Looking at this table, we can see that the coefficient of ozone depletion (ODP) is 0, but the global warming coefficient (GWP: relative value when CO2 … Read more

Principle of operation of equipment

Air conditioners, refrigerators, and heat pump water heaters are all driven with the same operating principle. Figure 1 shows the state that the air conditioner is doing the air conditioning as an example. First of all, the operating principle is explained based on this operation state. The evaporator as a heat exchanger, the condenser, the … Read more
