HEAT PUMP Russian patent published in 2004 - IPC

FIELD: heat pumps.

SUBSTANCE: proposed heat pump that uses heat of natural or man-made low-temperature sources to produce water for heating or hot-water supply at temperature of 50 to 70 °C has compressor, throttling device, as well as condenser and evaporator, each made in the form of tube-in-tube heat exchanger. External and internal pipelines of heat exchanger are made in the form of helical lines of equal diameter and turn lead of helix. Heated liquid inlet pipe is disposed on outlet end of heat-carrying agent and heated liquid outlet pipe, on inlet end of heat-carrying agent. Condenser can be disposed above evaporator. Compressor can be mounted inside evaporator.

EFFECT: reduced space requirement, enhanced mechanical strength of heat pump.
