Abstract

The invention discloses a high-environment-temperature air source swimming pool unit which comprises a compressor connected with the first input end and the first output end of a four-way reversing valve. The water side heat exchanger is connected with a second output end of the four-way reversing valve; the intermediate heat exchanger is respectively connected with the water side heat exchanger and a second output end connected with the four-way reversing valve; the first air side heat exchanger is respectively connected with the second input end of the four-way reversing valve, the water side heat exchanger and the intermediate heat exchanger; the second air side heat exchanger is respectively connected with the second input end of the four-way reversing valve, the water side heat exchanger and the intermediate heat exchanger; the high-environment-temperature air source swimming pool unit provided by the invention can be used for preparing hot water and cold water in a high-temperature environment; in a low-temperature environment, refrigeration operation can be realized, and more hot water can be prepared by utilizing a plurality of heat exchangers to absorb heat at a low temperature; the manufacturing cost is low, the structure is simple, popularization and application are convenient, and a new technical choice is provided for a swimming pool heat pump system.

Description

technical field [0001] The invention relates to the technical field of air source heat pump swimming pool systems, in particular to a high ambient temperature air source swimming pool unit. Background technique [0002] Swimming pool heat pump is a device that can obtain low-grade heat energy from natural air, water or soil, and use electricity to do work to keep the temperature of swimming pool water and high-level heat energy for dehumidification in the swimming pool room. [0003] At present, the constant temperature system of the air source heat pump swimming pool machine has both cooling and heating operations; and it needs to produce cold water at a lower temperature in a high-temperature environment; and high-temperature hot water in a low-temperature environment; cooling and heating are opposite processes, and the unit is in operation Under the two modes of operation, if the heat pump is designed according to the previous design method, it will cause the high-tempera...

[0003] At present, the constant temperature system of the air source heat pump swimming pool machine has both cooling and heating operations; and it needs to produce cold water at a lower temperature in a high-temperature environment; and high-temperature hot water in a low-temperature environment; cooling and heating are opposite processes, and the unit is in operation Under the two modes of operation, if the heat pump is designed according to the previous design method, it will cause the high-temperature environment to fail to produce low-temperature cold water, which will seriously cause high-pressure protection and high-temperature protection of the system; high-temperature hot water production in the high-temperature environment will lead to high pressure and excessive exhaust temperature. High; there is an urgent need for a constant temperature system for swimming pools. By controlling multiple heat exchangers, it is used to realize the technical problem of being able to produce hot water and cold water in high temperature environments. The technical problem of using multiple heat exchangers to absorb heat to produce more hot water at low temperature
