HEAT PUMP HEATING AND COOLING SYSTEM FOR APARTMENT HOUSES Russian patent published in 2021 - IPC F24F5/00 F24D17/00 F24D17/02 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, in particular to heating and air conditioning systems for buildings and structures. The heat pump heating and cooling system for buildings includes a heat pump (1) with a system for utilizing low-grade heat, a circulation hydraulic circuit (3) of a coolant. The heat exchanger (6) that utilizes the exhaust air heat is connected to the reverse branch (5) of the circulating hydraulic circuit (3) in series before the evaporator (E) of the heat pump (1). The condenser (C) of the heat pump (1) is connected to the heating system of the building.

EFFECT: resulting circulating circuit can be used both for cold supply for air conditioning devices with the simultaneous supply of low-grade heat for heat supply by a heat pump, and in the absence of demand for air conditioning, for the use of low-grade heat of the exhaust air for heat supply by a heat pump, reducing the number of pipe risers of an apartment houses from four to two.
