Processing Medium for Heat Pump

Updated: Jun 16

Previously, the working fluid for heat pumps was generally Freon. However, due to the destructive effect of Freon on the Earth's atmospheric ozone, in order to protect the Earth's ecological environment, in addition to improving the cooling coefficient of heat pumps and effectively utilizing energy, various countries are also committed to the development of new working fluids, and alternative working fluids to Freon have been applied.

However, today most HVAC manufacturers still use R22 as their working fluid, and the era of using environmentally friendly working fluids R417A and 134A has not yet arrived. Some countries, such as Japan, have taken the lead in using CO2 as a working medium, thus not causing damage to the ozone layer. (Therefore, during installation, the copper pipes must be tightly connected to prevent R22 from leaking out.)

In addition, the R22, R417A, 134A, and CO2 mentioned above do not cause harm to the human body. Even if there is leakage, the entire equipment is still safe.
