HEAT PUMP UNIT FOR HEATING, COOLING AND HOT WATER SUPPLY

摘要

FIELD: heat power engineering. SUBSTANCE: when the unit operates as a heat pump a heat of low potentiality is withdrawn from thermal water-carrying underground layers and soil massive by way of heat exchange in circulating heat carrier in gravitational heat pipe 16. The circulation is carried out under the action of gravity using heat exchangers 18 and 19. EFFECT: enhanced efficiency. 2 cl, 1 dwg
