What Kind of Refrigerant Do Heat
Pumps Employ
In the past, Freon was widely used for heat pump systems. At
first, Refrigerant R22 occupied the market. But with the awareness of its harm
to the ozonosphere, besides raising the COP of heat pumps, scientists strived
to develop new working medium to replace Freon.
Nowadays, R410A
and R407C are the most popular environmentally-friendly refrigerants.
The working
pressure of R410A is 1.6 times as high as that of R22. It has steady and
non-toxic performance. Free from chlorine, R410A does no harm to the
ozonosphere. It is accepted by the American and European countries.
R407C can work in the system of R22, but some components and lubrication
oil have to be changed. When filling the system, we must use liquid R407C for
its performance is not so steady.
