AIR CONDITIONER Russian patent published in 2013 - IPC F25B1/00 

FIELD: ventilation.

SUBSTANCE: conditioner (1) uses a refrigerating cycle comprising a compressor (21) which provides circulation of the coolant, and a tube (F) for the coolant, covered with a magnetic tube (F2) around the periphery, and comprises a coil (68), an electromagnetic induction thermoresistor (14) and a controller (11). The coil (68) generates a magnetic field for induction heating of the magnetic tube (F2). The electromagnetic induction thermoresistor (14) detects the temperature of the coolant which passes through the accumulating unit (F), which is at least one part of the refrigerating cycle. The controller (11) allows the generation of a magnetic field by means of the electromagnetic field generator when the condition of permit of generation of electromagnetic field is met. The condition of permit of generation of electromagnetic field is a condition where the temperature detected by the electromagnetic induction thermoresistor varies between two states of the output signal of the compressor (21).

EFFECT: conditioner can prevent excessive temperature increase of the coolant even when the coolant is heated by electromagnetic induction heating method.
