Dual-evaporation dual-condensation household type central air-conditioning hot water system and control method thereof

Abstract

The invention discloses a dual-evaporation dual-condensation household type central air-conditioning hot water system. A compressor is connected among the corresponding interfaces of a four-way valve; a branch of a first interface of an outdoor heat exchanger is communicated with the corresponding interface of the four-way valve through a first electromagnetic valve; another branch of the first interface of the outdoor heat exchanger is communicated with a refrigerant inlet of a heat storage water tank through a second electromagnetic valve; a second interface of the outdoor heat exchanger is communicated with a first interface of a wind plate surface air cooler through a third electromagnetic valve and an expanding valve; one branch of the corresponding interface of the four-way valve is communicated with a second interface of the wind plate surface air cooler through a seventh electromagnetic valve after the corresponding interface of the four-way valve passes through an eighth electromagnetic valve; another branch of the corresponding interface of the four-way valve is communicated with the refrigerant inlet of the heat storage water tank through a sixth electromagnetic valve; one branch of a refrigerant outlet of the heat storage water tank is communicated with the second interface of the outdoor heat exchanger through a fourth electromagnetic valve and the third electromagnetic valve; and another branch of the refrigerant outlet of the heat storage water tank is communicated with the second interface of the outdoor heat exchanger through a fifth electromagnetic valve, the expanding valve and the third electromagnetic valve. The dual-evaporation dual-condensation household type central air-conditioning hot water system can provide a summer refrigeration heating recovery and single refrigeration mode and a winter single warming and heating water mode.

Description

technical field [0001] The invention relates to a double evaporating and double condensing household central air-conditioning hot water system, in particular to a double evaporating, double condensing, double evaporating and double condensing household central air-conditioning hot water system and a control method thereof. Background technique [0002] At present, the existing household central air-conditioning systems include split air-conditioning and multi-connected air-conditioning systems, and domestic hot water is generally realized by installing solar water heaters or air-source water heaters; For water supply, air-conditioning system and hot water system need to be installed separately, which leads to problems such as large investment, complex system, and high energy consumption of the whole system, which are specifically reflected in: [0003] 1) The applicable room area of ​​the split air conditioner is 10-17m2 2 , flexible installation, the average family needs t...
