ABSTRACT:
Disclosed is a compact heat pump using water as refrigerant, including a casing having a first and second end sections and an intermediate section located therebetween, with an evaporator located at the first end section, configured for containing said water and allowing evaporation of at least a part of the water to produce vapor and remove heat from the remainder of the water. At least one agitator scoop is located within said evaporator, with one or more demisters installed between the evaporator and the compressor. The one or more compressors induce evaporation by maintaining vacuum at least at an intake conduit, and are configured for receiving the vapor through the intake conduit after passing through a heated demister. The condenser is configured for receiving the compressed vapor from the compressor, lowering the vapor temperature and condensing it back into a liquid state.
