なわれるという欠点を有していた。Conventional configuration and its problems Conventionally, in air conditioners equipped with a refrigerant heater, when heating starts, the refrigerant in the outdoor heat exchanger is removed by a compressor in order to ensure the amount of refrigerant circulation. Although a refrigerant extraction operation is being performed, the compressor is stopped when the refrigerant heater is not in a state to start heating after the refrigerant extraction operation is completed. However, if the compressor is restarted at the same time as the refrigerant heater starts heating, it takes time for the refrigerant to circulate properly, so the refrigerant absorbs less heat in the refrigerant heater and starts to rise slowly. Furthermore, the refrigerant heater also has the disadvantage that the generated heat is not carried away by the refrigerant, resulting in an overheated state, which impairs the safety of the refrigerant heater.

3. The outdoor fan motor 14 is energized, and the refrigerant flows through a normal refrigeration cycle as indicated by the solid arrow. When the contact piece of the cooling/heating changeover switch 12 is turned to the B side for heating operation, the outdoor fan motor 14 is not energized, the four-way valve 2 is energized, and the two-way valve 8 is closed, so the outdoor heat exchanger 6 and the refrigerant are energized. When the compressor 1 is operated, the refrigerant in the heater 9 is transferred to the indoor heat exchanger 3 in a so-called refrigerant extraction operation. Timer 1 after a certain period of time
By closing the contact point 5, the two-way valve 8 is opened, and the refrigerant in the indoor heat exchanger 3 passes through the refrigerant heating circuit 7 and is sucked into the compressor 1. Due to the action of the check valve 10, the refrigerant does not flow into the outdoor heat exchanger 6.
In other words, the refrigerant is transferred to the compressor 1, as shown by the broken line arrow.
The air flows through the four-way valve 2, the indoor heat exchanger 3, the two-way valve 8, the refrigerant heater 9, and the heating cycle back to the flow compressor 1. In the refrigerant heater 9, the oil vaporization heater 18 is energized from the start of operation, and when the temperature at which oil can be vaporized is reached, the contact of the thermostat 20 falls from the D side to the C side, and the electricity to the oil vaporization heater 20 is stopped. , the igniter 16 and the oil pump 17 are now energized. When the thermostat 19 detects ignition, its contacts open and the igniter 16 stops.

る。 When this air conditioner starts heating operation when it has not been operated for a long time and the temperature has become equal to the ambient temperature,
Normally, the time for the oil vaporization heater 18 to reach the temperature at which oil can be vaporized is longer than the time during which the refrigerant draining operation is performed, but in the present invention, after the refrigerant drawing operation is completed, the oil vaporization heater 18 does not reach the temperature at which it can vaporize and heats the refrigerant. Even if the container 9 does not start heating, the operation of the compressor 1 continues. Normally, it takes some time for the refrigerant to circulate properly after the compressor starts operating, but by continuing to operate the compressor 1 even after the refrigerant removal operation ends, the refrigerant heater 9 heats up. When starting, ensure good circulation of the refrigerant and turn on the refrigerant heater 9.
It is possible to effectively transport the heat generated indoors, improving the start-up time during heating. Moreover, since overheating is also prevented in the refrigerant heater 9, the safety of the refrigerant heater 9 itself is improved. In this embodiment, petroleum was used as the heat source for heating the refrigerant, but the present invention is also effective with other heat sources such as solar heat.
