FIELD: power engineering.
SUBSTANCE: invention relates to equipment used to cool or heat, comprising at least compressor (1), condenser (2), control device (7), evaporator (9) and cavity (10) for accumulation of fluid. Invention differs by control system comprising electronic device (4) for detection of bubbles intended for detection of bubbles in coolant condensate. Device (4) for detection of bubbles is connected near outlet of condenser (2) or its output line and is electrically connected to control device (7), which is controlled by electric method. Device (4) for detection of bubbles supplies signals to control device (7). Gas bubbles in liquid condensate act at control system so that when number of detected bubbles, and it means signal analysed by device (4) for bubbles detection exceeds specified value complying with permissible number of bubbles in condensate, and this signal is sent into electric controller (7) of control device to terminate supply of coolant or reduction of its flow.
EFFECT: invention provides for control of liquid flow supplying from condenser or heat exchanger, so that non-condensed gas does not reach control device.
