Problems solved by technology
[0004] At present, the antifreeze measures adopted by most manufacturers are to add antifreeze liquid in the water to prevent the equipment from freezing, but most of the antifreeze will corrode the equipment and shorten the service life of the equipment.
Some units do not add antifreeze and only keep the expansion tank connection pipe warm, which can only delay the freezing process, because there is no heat source to supplement the heat, and it will still freeze after a long time; electric heaters can effectively prevent freezing, but they need continuous consumption Electricity, and electric heaters have safety risks of aging and leakage

Embodiment Construction
[0030] see in conjunction Figure 1 to Figure 2 As shown, according to the embodiment of the present invention, a water cycle power module is provided, including an expansion tank 1 and a water pump 2. The water pump 2 has a water inlet pipe 21 and a water outlet pipe 22. It can be understood that the water inlet pipe 21 and the water outlet pipe 22 forms a water system circulation with a heat exchanger (not shown in the figure). Specifically, the water system circulation can be, for example, a floor heating system for a temperature-adjusted space, and the heat exchanger and a compressed refrigerant air conditioning system (not shown in the figure shown), objectively, the water temperature in the water inlet pipe 21 is higher than the water temperature in the water outlet pipe 22, and the expansion tank 1 has a connecting pipe communicated with the water inlet pipe 21 11, to lead out the water part in the water inlet pipe 21 to the expansion tank 1, and then when the high pres...

The present invention provides a water cycle power module and its antifreeze control method, and an air-conditioning unit, wherein the water cycle power module includes an expansion tank and a water pump, the water pump has a water inlet pipe, and the expansion tank has a connecting pipe communicating with the water inlet pipe , the pipeline of the connecting pipe is partly connected to the water inlet pipe for heat exchange. According to the present invention, the connecting pipe of the expansion tank is at least partly heat-exchanged connected with the water inlet pipeline of the water pump, and the heat of the water inlet pipeline of the water pump is used to increase the temperature of the connecting pipe, which is beneficial to improve the antifreeze ability of the expansion tank.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a water cycle power module, an antifreeze control method thereof, and an air conditioning unit. Background technique [0002] The expansion tank is a key component of the water cycle power module of the air source heat pump unit. The expansion tank is connected to the water system through the expansion tank joint to buffer the pressure fluctuation of the water system. When the pressure of the waterway system is too high, water will enter the expansion tank through the expansion tank joint to reduce the pressure of the waterway system and protect the components of the waterway system from being damaged due to excessive pressure. [0003] Due to structural limitations, most expansion tanks need to be connected to the water system through a connecting pipe. Generally, the temperature detection points of the antifreeze control of the central air-conditioning chil...
