Portable Air Conditioner Heater – Refrigerant (R-22).

This refrigerant R-22 has been replaced by the R407C and R410A, substitutes meet certain characteristics: They do not damage the ozone layer, have low greenhouse,  they are not toxic or flammable. They are stable under normal conditions of pressure and temperature and are energy efficient.

Heater and Air Conditioner Wall Unit – (R-410A).

It is a chlorine-free refrigerant (CFC's and HCFC's) and therefore not harmful to the ozone layer and its use is not subject to any withdrawal process. Has a high energy efficiency, is a unique mixture and thus facilitates future maintenance savings. Non-toxic and non-flammable and recyclable and reusable. This refrigerant is not compatible with air conditioning systems operating with R-22.

Heater and Air Conditioner – (R-407C).

It is a chlorine-free refrigerant (CFC's and HCFC's) and therefore not harmful to the ozone layer and its use is not subject to any withdrawal process. It has thermodynamic properties very similar to R-22. Unlike the R-410A is a mixture of three gases R-32, R-125 and R-134A. If a component needs to be replaced refrigerator or a rupture of one of them, the system must be purged completely. 

Water Heater Air Conditioner – (R-134A).

It is a chlorine-free refrigerant (CFC's and HCFC's) and therefore not harmful to the ozone layer and its use is not subject to any withdrawal process. It is widely used in other industries: automotive air conditioning, refrigerators, pharmaceutical aerosol propellant.
