HEAT PUMP Russian patent published in 2004 - IPC

FIELD: heat energy conversion equipment, particularly heat pump, refrigerator, energy transformer. SUBSTANCE: heat pump comprises cylinder, vessel for working substance and two non-communicated circulation loops with liquid heat-transfer agents. Each loop includes two heat exchangers. One heat exchanger of the first loop is placed into cooled medium, one heat-exchanger of the second loop is located into heated medium. The second heat exchangers are disposed into working substance vessel. Pressure source has two adjoining containers connected by common cylinder in which two pistons are located. Pistons are joined to each other by rigid rod. Cylinder is divided into two equal parts by fixed partition having orifice for rod. Pressure source is connected to cylinder parts through channels formed into partition for alternately pressurizing of the first or the second cylinder parts which results in piston necessary displacement in two opposite directions. Container inner surfaces and cylinder inner surface from the side of adjoining containers connection may be heat-insulated. EFFECT: increased heating factor and enhanced heat pump capacity. 2 cl, 2 dwg
