In addition to connecting the refrigerant circuit, a burner 18 for heating the refrigerant is provided.The heating cycle in a steady state is performed by opening the third solenoid valve 16 and closing the first solenoid valve 5 and the second solenoid valve 7. The refrigerant liquid is sent to the refrigerant heater 17 by the refrigerant pump 16, heated and evaporated by the burner 18, and condensed and liquefied by the indoor heat exchanger 9 to radiate heat, thereby forming a heating cycle for heating the refrigerant. However, during transient operation at the start of heating, the outdoor heat exchanger 3 under low outside temperature
, the refrigerant accumulated in the compressor 1 and accumulator 8,
In order to pump the air to the heating cycle circuit side, the first solenoid valve 5
By performing heat pump operation with the second solenoid valve 7 open and pump-down operation with the first solenoid valve 6 closed, the charged refrigerant is effectively used and a stable heating cycle is balanced. . In this transient operation, the refrigerant liquid flowing out of the refrigerant liquid pipe 11 from the indoor heat exchanger 9 is branched at the branch part 13 to the refrigerant pump 16 side and the outdoor heat exchanger 3 side. A feature of the present invention is that the outflow dynamic pressure of the refrigerant liquid in the branch part 13 acts more on the refrigerant pump 16 side.As shown in FIG. The outflow dynamic pressure A from the exchanger 9 acts more on the refrigerant pump 16 side B, and the outdoor heat exchanger 3111! It is designed so that almost only static pressure acts on the IC.

る。As is clear from the above embodiments, the air conditioning system of the present invention is a heat pump in which a compressor, a four-way valve, an outdoor heat exchanger, a first solenoid valve, a throttle device, an indoor heat exchanger, and a second solenoid valve are connected in an annular manner. A refrigerant circuit for heating the refrigerant consisting of a third solenoid valve, a refrigerant pump, and a series branch of a refrigerant heater is provided between the refrigerant liquid pipe and the refrigerant gas pipe during heating in the type cooling/heating refrigerant circuit, via a branch part. , during heating, the branch part in the refrigerant liquid pipe,
The dynamic pressure of the refrigerant flowing out from the indoor heat exchanger side is made to be greater than the dynamic pressure flowing out to the refrigerant pump side, and when heating starts, the dynamic pressure of the refrigerant flowing out is applied to the refrigerant pump side more. This provides a backup effect for the refrigerant pump, increases the amount of refrigerant circulated to the refrigerant heater, prevents abnormal temperature rises when heating the refrigerant in the burner, and improves the thermal stability of the refrigerant. Even during transient operation at the start, the amount of refrigerant circulating to the refrigerant heater is ensured, and the refrigerant heating and heating by the burner can be started quickly and reliably. Since the dynamic pressure flowing out from the refrigerant has the effect of a back amplifier, a stable refrigerant heating cycle can be maintained over a wide range of operations.
