Since the refrigerant introduced into the outdoor auxiliary heat exchanger 7 is the refrigerant discharged from the indoor heat exchanger 3 and not throttled by the first throttling member 5, the temperature of the refrigerant introduced into the outdoor auxiliary heat exchanger 7 is higher than the temperature of the refrigerant introduced into the outdoor heat exchanger 4. So that the temperature of the air heat-exchanged by the outdoor auxiliary heat exchanger 7 is higher than that of the outdoor heat exchanger 4.
Because the outdoor auxiliary heat exchanger 7 is arranged at the upstream of the outdoor heat exchanger 4, the air after heat exchange of the outdoor auxiliary heat exchanger 7 can heat the outdoor heat exchanger 4 in a defrosting mode, so that the aim of defrosting the outdoor heat exchanger 4 is fulfilled.

Meanwhile, the refrigerant entering the outdoor auxiliary heat exchanger 7 flows out of the outlet of the indoor heat exchanger 3, so that the refrigerant flow of the indoor heat exchanger 3 is not reduced in the whole circulation process, and the problem of insufficient indoor heat supply does not exist. And because the outdoor heat exchanger 4 is not defrosted by using the electric auxiliary heating device, the safety problem caused by touching the electric auxiliary heating device does not exist.
As shown in fig. 1, in some embodiments of the present invention, the outlet end of the outdoor auxiliary heat exchanger 7 is connected between the first throttling element 5 and the indoor heat exchanger 3. Specifically, the refrigerant discharged from the outlet end of the outdoor auxiliary heat exchanger 7 and the other refrigerant discharged from the indoor heat exchanger 3 are collected, subjected to throttling and pressure reduction by the first throttling element 5, and then discharged to the outdoor heat exchanger 4 for condensation and heat dissipation, so that the situation that the return air temperature is too high does not occur.
In some embodiments of the present invention, as shown in fig. 1, the compressor 1 has an air supply port c, the air processing apparatus 100 further includes a gas-liquid separator 11 and a second throttling element 6, the gas-liquid separator 11 includes a first interface h, a second interface m and a gas outlet n, the second throttling element 6 is respectively connected to the first interface h and the second end of the indoor heat exchanger 3, the first throttling element 5 is respectively connected to the second interface m and the second end of the outdoor heat exchanger 4, and the gas outlet n is connected to the air supply port c. Alternatively, the second throttling element 6 may be a throttle valve or an electronic expansion valve, so that the temperature of the throttled refrigerant can be adjusted.
Specifically, the gas-liquid separator 11 has a gas-liquid separating function, and the second throttling element 6 has a throttling and depressurizing function. In the cooling mode, the refrigerant discharged from the outdoor heat exchanger 4 may be throttled by the first throttling element 5 to be reduced into a gas-liquid two-phase refrigerant, the gas-liquid two-phase refrigerant is discharged from the second port m into the gas-liquid separator 11 to be separated into a gas and a liquid, and the separated gas refrigerant may be discharged from the gas outlet n to the gas supply port c of the compressor 1, and the refrigerant discharged from the gas return port b and the gas supply port c back into the compressor 1 is compressed while being mixed to form exhaust gas.

In some embodiments of the present invention, as shown in fig. 1, the air processing apparatus 100 further includes a detection device 12 for detecting the temperature of the outdoor heat exchanger 4, the detection device 12 is connected to the control device 10, and the control device 10 controls the control valve 9 to open or close according to the detection result of the detection device 12. Specifically, in the heating mode, the detection device 12 detects the real-time temperature of the outdoor heat exchanger 4 and transmits the real-time temperature to the control device 10, and when the control device 10 determines that the real-time temperature satisfies the defrosting condition, the control device 10 controls the control valve 9 to open, and a part of the refrigerant discharged from the indoor heat exchanger 3 flows to the outdoor auxiliary heat exchanger 7 to defrost the outdoor heat exchanger 4 by using the heated air, so that whether defrosting is performed or not can be determined according to the actual temperature of the outdoor heat exchanger 4, the automation degree of the air treatment device 100 is improved, and the defrosting condition when no frost exists is avoided.
