Hitachi Highly HWHP - JOAP

PRINCIPLE OF HPWH 2. Heat exchanger(water tank) Heat of 4000W is rejected emitted into water by condensing refrigerant. 3. Expansion valve The temperature of refigerant decreases after expansion valve. 4. Heat exchanger(main unit) Heat of 3000W is absorbed from ambient by evaporating refrigerant. 1. WHP compressors specially designed for Heater Pump Water Heater application. The compressed refrigerant with high temperature is obtained by compressors which consume electric energy.
