The refrigerant ,which is in a liquid state absorbs free energy from the air and evaporates in this process .A sensor in the expansion valve ensures that the liquid refrigerant collects the correct amount of the “free energy” before the refrigerant (now in a gas state) is led into the compressor. The compressor increase the pressure of the refrigerant .The warm gas is then led into the condenser. The refrigerant (gas state) meets the water from the heating system will be cooled by the circulating heating water, it condenses into a liquid state. Energy is emitted in this process to the hot water. After the condenser, the refrigerant which is now in liquid form , continues through a drying filter. The drying filter is used to collect any moisture in the system .After the filter it continues on to an expansion valve. The refrigerant pressure is lowered in the expansion valve. This also cause the temperature to drop .When the refrigerant has left the valve and passes the evaporator it changes to vapor again. The completes the refrigerant circuit. The expansion valve is equipped with a sensor (blub) just before the compressor. The sensor controls the amount of fluid.

 

Nano coating for the coil: The coil use nano coating technology, uneasy for scale deposit,corrosion resistance and can clean itself.
Integrated design:it’s easy for connection and installation.
Beautiful appearance:Complete desigh make it beautiful.
