FIELD: transport.
SUBSTANCE: invention relates to system for cooling and heating automobile cabin. System comprises coolant circuit 2 with, at least, compressor 5, liquid-cooled condenser 6, liquid-heated evaporator 7, and two external secondary circuits 3, 4. First circuit 3 includes elements 13 arranged in space to be cooled and heated. Flow switch 16 communicates element circuit 3 and radiator circuit 4 to make het pump. Said switch flow 16 is composed of valve 16a, 16b to allow coolant flow 4b to bypass radiator 15.
EFFECT: efficient cooling and/or heating without reversing coolant in radiator circuit.
