[0040] Reference again Figure 1 , Figure 2 , Figure 3 In a preferred embodiment of the present invention, the water pump 226 is vertically arranged on the right side of the gas-liquid separator 222. The water pump 226 has an inspection port 2261, which faces the right side wall 13. The right side wall 13 is provided with a water pump maintenance cover 133. The water pump maintenance cover 133 is arranged corresponding to the water pump inspection port 2261, so as to facilitate the maintenance of the water pump 226. The outlet of the water pump 226 is connected to the water outlet joint 132, which is arranged on the right side wall 13 and located in the lower area of ​​the water pump 226. A branch pipeline 220 is formed between the outlet of the water pump 226 and the water outlet joint 132 to communicate with the expansion tank 221.

The water-side heat exchanger 227 is located above the water pump 226 and fixed to the rear side wall 15. The inlet of the water-side heat exchanger 227 is connected to the water inlet joint 131. A water flow switch 228 is provided on the pipeline between the inlet of the water-side heat exchanger 227 and the water inlet joint 131. The water inlet joint 131 is preferably provided in the area above the water pump 226. The water-side heat exchanger 227 is provided above the water pump 226, which can make full use of the space above the water pump 226 and is conducive to cleaner water blowing and drainage of the water-side heat exchanger 227. In the present embodiment, the water inlet joint 131 and the water outlet joint 132 are respectively located above and below the water pump 226, so that the gaps between the components can be fully utilized for piping, thereby improving the space utilization rate in the second installation cavity 22 and realizing a reasonable layout; further, the part of the water outlet joint 132 extending out of the right side wall 13 is connected to a drain valve 1321, which can drain water as needed, thereby improving the convenience of operation.

[0042] In the preferred embodiment of the present invention, Figure 5 , Figure 6 As shown, the pressure relief valve 231 is located at the top of the second installation cavity 22 and is connected in series to the pipeline between the outlet of the water side heat exchanger 227 and the inlet of the water pump 226, and the pressure relief outlet 2311 of the pressure relief valve 231 is away from the electronic control component 214; the safety valve 232 is connected in series with the pressure relief valve 231 and is located below the pressure relief valve 231, and the water outlet 2321 of the safety valve 232 is set toward the chassis 11.

[0043] Through the above-mentioned method, the pressure relief valve 231 is located at the top of the second installation cavity 22, which can ensure that the air in the pipeline between the water-side heat exchanger 227 and the water pump 226 is completely discharged, thereby improving the pressure relief effect; the outlet of the pressure relief valve 231 is away from the electronic control component 214, which can prevent the water vapor sprayed by the pressure relief valve 231 from entering the electronic control component 214, thereby protecting the circuit structure in the electronic control component 214, and is beneficial to improving the service life of the electronic control component 214; the water outlet 2321 of the safety valve 232 is set toward the chassis 11, which is beneficial to draining water onto the chassis 11 and improving the drainage efficiency.

[0044] In a preferred embodiment of the utility model, a low-pressure valve 233 and a high-pressure valve 234 are also included, which are arranged below the water pump 226 to fully utilize the space below the water pump 226 for piping.

[0045] like Figure 7As shown, this embodiment provides a schematic diagram of the pipeline connection of an integrated natural fluorine-water heat pump unit. The four interfaces of the water-side heat exchanger 227 are respectively connected to the refrigerant-side heat exchanger 212, the low-pressure valve 233, the water inlet joint 131, and the water outlet joint 132. One interface of the four-way valve 224 is connected between the low-pressure valve 233 and the indoor unit (not shown in the figure). The pipeline connection method of the remaining components is a common application form in this field and will not be repeated here. When using the floor heating mode, the refrigerant at the outlet of the compressor 31 returns to the compressor through the oil separator 223, the four-way valve 224, the water-side heat exchanger 227, the throttle valve-refrigerant-side heat exchanger 212, the four-way valve 224, and the gas-liquid separator 222 in sequence. The refrigerant in the water-side heat exchanger 227 exchanges heat with the water in the water-side heat exchanger 227 to heat the floor heating module (not shown in the figure). The other refrigerant at the outlet of the four-way valve 224 returns to the compressor 31 after passing through the indoor unit, the throttle valve, the refrigerant side heat exchanger 212, etc. It should be noted that technicians can adjust the pipeline connections between the above components according to actual needs, and this embodiment does not limit the specific connection form of the pipeline.
