FIELD: heating systems.
SUBSTANCE: invention refers to heat engineering, and namely to heat pump devices. Heat pump includes evaporator, capacitor, throttle shutoff and control valves and vacuum pump, which are in-series included in closed circulation circuit of cooling agent. Vacuum pump is made with possibility of pumping cooling agent vapours with speed of 350 l/s within pressure range of 133 to 0.53·105 Pa. Invention provides the possibility of using a wide range of high-boiling matters as heat carriers with Tboiling >273°K at atmospheric pressure of matters. The most preferable is ethanol and its water solutions.
EFFECT: developing compact heating systems which do not require fuel margins and special communications, advantageous as to power and economy, and environmentally safe.
