DEVICE FOR MAINTAINING THE TEMPERATURE REGIME OF THE CONSUMER AND METHOD FOR ITS OPERATION Russian patent published in 2023 - IPC F25B1/00 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat engineering, namely to systems for regulating the thermal regime of various installations. The device for maintaining the temperature mode of the consumer contains the first and second circulation circuits of the cooling liquid and the circuit of the refrigerating machine. The first circulation circuit includes a pump (1), liquid-air heat exchanger (4) with one fan (7), temperature sensors (9, 10), locking elements (5, 6). The second circulation circuit includes a pump (11). The refrigeration circuit includes a compressor (8), a condenser (12), a throttle (13) and an evaporator (2). The evaporator (2) is a common element for the chiller circuit and the primary circuit, the condenser (12) for the chiller circuit and the secondary circuit, and the heat exchanger (4) for the primary and secondary circuits. The pump (1) of the primary circuit is connected to the consumer (3) through the evaporator (2) and the heater (14), installed in such a way that the outlet of the evaporator (2) is connected to the inlet of the heater (14), and the outlet of the heater (14) is connected to the inlet consumer (3). Also disclosed is a method for operation of the temperature maintenance device.

EFFECT: improving the maintenance of the operating temperature of the heat consumer within the specified limits.
