1.2. Working Principle:
In the heat pump dryer machine, heated air is sent to the wet laundry in the drum from the
heater side of the coil which called by condenser. The humidity of the laundry is taken and
reaches the cold side of the coil which called by evaporator via filter. With a compressor,
refrigerant is passed through inside of the tubes of coils both condenser and evaporator. A
capillary causes resistance against to refrigerant flow. By this way, the evaporator surface is
cooled and condenser surface is heated. The hot and humid air from the drum is reached cold
evaporator surface and the humidity on it is left as water. The condensing water in the
evaporator is pumped to the water tank by the pump.
