Title: Fault detection circuit
Inventor: NAKANO YOSHIAKI
IPC: H04B17/00
Filed: 1987-12-16
Abstract: PURPOSE:To reduce the adjustment man-hour by providing a feedback circuit controlling a gate voltage so that a difference between a reference voltage and a drain voltage reaches a prescribed value thereby detecting the voltage fluctuation between the gate and source of a field effect transistor(TR). CONSTITUTION:The constitution is adopted such that the emitter and collector of the TR are connected to the drain and base of the FET whose drain receives the 1st constant voltage VDD via a resistor R1, whose gate receives a 2nd constant voltage VGG via a resistor R4, and whose source receives a prescribed voltage respectively, and the voltage VDD and VGG of the TR are used to apply a bias voltage. Then the change in the drain-source voltage VDS of the FET 1 is fed back to the gate-source voltage VGS via a common base TR 2, then the voltage VGS is changed to compensate the change in the voltage VDS thereby making the voltage VDS automatically constant. Thus, the fluctuation in the DC characteristic of the FET 1 is detected by monitoring the change in the voltage VGS and since there is no moving part employed, the adjustment man- hour is saved.

CONSTITUTION: The cycle of a refrigerant in a refrigerant circuit 10 is changed over between the cooling operation and the heating operation by switching first and second four-way selector valves 2 and 19. In the cooling operation, a refrigerant is circulated through a compressor 1, an outdoor heat exchanger 3, a decompression mechanism 5 and a room heat exchanger 6 in the order and in the heating operation, it is circulated through the compressor 1, the room heat exchanger 6, a decompression mechanism 4 and the outdoor heat exchanger 3 in the order to transfer heat in a room outside it. In this manner, an air conditioning is performed by this heat pump cycle.  In this case, the selector valves 2 and 19 are arranged in parallel respectively across a discharge line 8a and a suction line 8b of the compressor 1, so that a high pressure gas is always introduced into both the four-way selector valves 2 and 19. This secures a pressure difference between the selector valves 2 and 19 in the switching for various operations, thereby effectively preventing error action in switching.
