example 1

[0034] Example 1: When the first four-way valve 2 and the second four-way valve 3 are in the closed state; the third electronic expansion valve 13 and the fourth electronic expansion valve 15 are in the closed state; the second electronic expansion valve 11 is in the state of automatically adjusting the opening degree , the heat pump system operates in the hot water heating mode, where the cycle of the refrigerant is:

[0035] Compressor 1 discharges high-temperature and high-pressure gas → the first connection port D1 and the third connection port C1 of the first four-way valve 2 → the fifth connection port D2 and the seventh connection port C2 of the second four-way valve 3 → hot water condenser Condensate heat in 5, discharge high-pressure liquid → first one-way valve 10 → two-way multi-pipe high-pressure liquid storage tank 17 → throttling into low-temperature and low-pressure liquid at the second electronic expansion valve 11 → absorb heat in outdoor condenser 6, discharge...

example 2

[0037] Example 2: When the heat pump system is used for cooling water, the first four-way valve 2 is in the open state, and the third four-way valve 4 is in the closed state; the third electronic expansion valve 13 and the fourth electronic expansion valve 15 are in the closed state; An electronic expansion valve 9 is in the state of automatically adjusting the opening degree. The heat pump system operates in the cooling water mode, and the circulation process of the refrigerant is:

[0038] Cooling water: compressor 1 discharges high-temperature and high-pressure gas → the first connection port D1 and the fourth connection port E1 of the first four-way valve 2 → the ninth connection port D3 and the eleventh connection port C3 of the third four-way valve 4 → Condensate and release heat in the outdoor condenser 6, discharge high-pressure liquid → second one-way valve 12 → two-way multi-pipe high-pressure liquid storage tank 17 → throttling into low-temperature and low-pressure ...

Abstract

The invention discloses a heat pump system and a control method thereof. The heat pump system comprises a compressor (1), a first four-way valve (2), a second four-way valve (3), a third four-way valve (4), a first heat exchanger (5), a second heat exchanger (6), a third heat exchanger (7), a fourth heat exchanger (8), a first throttling assembly, a second throttling assembly, a third throttling assembly and a fourth throttling assembly. According to the heat pump system and the control method of the heat pump system provided by the invention, the heating and refrigerating effects of the heat pump system are better.

Description

technical field [0001] The invention relates to the field of heat pumps, in particular to a heat pump system and a control method thereof. Background technique [0002] At present, there are many swimming pool air conditioners on the market, and their main functions include constant air temperature in the swimming pool room, dehumidification and constant temperature heating of pool water. More advanced swimming pool heat pump products integrate pool water heating, indoor air dehumidification, indoor air cooling and heating. However, the heat pump system has the following disadvantages: First, when the pool water is heated for the first time, the unit heats the pool water by extracting the heat energy of the indoor air. This heating method allows the unit to reduce the indoor air temperature while heating the pool water, and the indoor temperature gradually drops. , will affect the heating effect of the pool water; some swimming pools use other methods to heat the pool water...
