Water heater with tank and heat pump - has condenser in tank lower part utilising refrigerator heat

摘要

The water heater has lagged tank with a condenser of a heat pump in the lower part of the tank associated with a refrigerator. All the heat extracted during the refrigeration process is transferred to the water for heating. The lower part of the boiler can be cooled. A ventilated channel is arranged between the boiler wall and thermal insulation layer. This channel has a flap controlled by the boiler temp. in the region of a condenser. This flap is opened by an actuator against the force of a spring and natural convection.
