なうものである。2. Description of the Related Art FIG. 4 shows a conventional example of an air conditioner using a heat pump driven by an engine. That is, the refrigerant from the compressor 2 driven by the engine 1 is sent to the indoor heat exchanger 4 via the four-way valve 3 to be liquefied as shown by the arrow, and the liquefied refrigerant is fed to the pressure reducing valve 5. Then, it is sent to the outdoor heat exchanger 6 to be vaporized, and the vaporized refrigerant is returned to the compressor 2 via the four-way valve 3, the check valve 7 and the accumulator 8 so that the indoor heat The heat of the exchanger 4 is used to heat the room.

ものである。The refrigerant that has passed through the indoor heat exchanger 4 is supplied to the refrigerant heater 11 through the pressure reducing valve 10 when the solenoid valve 9 is opened. Cooling water for cooling 1 is circulated, and the refrigerant is heated and vaporized by this cooling water, and the vaporized refrigerant is the solenoid valve 9 and the accumulator 8
After that, the waste heat of the engine 1 is utilized to improve the heating capacity.

は困難である。Thus, in the above configuration, as shown in the Mollier diagram of FIG. 5, the refrigerant heating process by the refrigerant heater 11 shown between points C and F and the outdoor heat exchanger shown between points D and E. Since there is a pressure difference between the refrigerant and the evaporation process of 6, it is difficult to simultaneously suck the refrigerant from these into the compressor 2.

らの冷媒の圧力よりも大であるので、室外側熱交換器６

ない。Therefore, conventionally, the solenoid valve 9 is periodically opened and closed so that the refrigerant from the outdoor heat exchanger 6 is sucked into the compressor 2 when the solenoid valve 9 is closed, and the refrigerant heating is performed when the solenoid valve 9 is opened. The refrigerant from the container 11 is sucked into the compressor 2. When opening the solenoid valve 9,
Since the pressure of the refrigerant from the refrigerant heater 11 is greater than the pressure of the refrigerant from the outdoor heat exchanger 6, the outdoor heat exchanger 6
The refrigerant from is not sucked by the compressor 2.

て、性能が低下し、効率が低下するという問題がある。In the conventional structure, the solenoid valve 9 is periodically opened and closed to alternately suck the refrigerant from the refrigerant heater 11 and the refrigerant from the outdoor heat exchanger 6 into the compressor 2. Therefore, there is a problem that an operating loss occurs due to opening / closing of the solenoid valve 9, performance is reduced, and efficiency is reduced.

率が低くなる問題がある。Incidentally, in order to make the pressure of the refrigerant sucked into the compressor 2 constant, it is conceivable to connect the outdoor heat exchanger 6 and the refrigerant heater 11 in series, but this is the case. However, there is a problem that the flow resistance of the refrigerant becomes large and the efficiency also becomes low.

Therefore, the gaseous refrigerant compressed by the compressor 21 is supplied to the outdoor heat exchanger 25 via the four-way valve 22 and the check valve 45 and condensed as shown by the broken line arrow to become a liquid refrigerant. The liquid refrigerant from the outdoor heat exchanger 25 is decompressed by the pressure reducing valve 24 and then supplied to the indoor heat exchanger 23, where it is evaporated and becomes a gaseous refrigerant.

きる。In the ejector 27, since the refrigerant driving flow F30 from the refrigerant heater 30 sucks the refrigerant suction flow F25 from the outdoor heat exchanger 25, the driving flow F30 and the suction flow F25 are smoothly performed. When the refrigerant heater and the outdoor heat exchanger are connected in series, the pressure in the outdoor heat exchanger 25 can be kept low by the suction action of the driving flow F30. Unlike the above, the evaporation temperature of the refrigerant in the outdoor heat exchanger 25 can be lowered, the temperature difference from the outside air can be increased, the amount of heat absorbed can be increased, and the heating capacity can be increased. .
