Working Medium Of Heat Pump

The working quality of the heat pump was generally Freon before, but because Freon has a damage effect on the earth's atmospheric oxygen. In order to protect the ecological environment of the earth, in addition to improving the refrigeration coefficient of the heat pump and effective use of energy, sciences in various countries are also committed to the development of new types of work. It has been applied to replaced Freon. However, the working quality of most Chinese manufacturers today is still R22, and the era of environmentally friendly construction R417A and 134A has not yet arrived. Some countries such as Japan have taken the lead in using CO2 as work quality, which will not cause damage to the ozone layer. (So during installation, the copper tube must be closely connected to prevent R22 from leaking out.) In addition, the R22, R417A, 134A, and CO2 described above will not cause damage to the human body.
