During the use of heating and cooling air conditioners, a large amount of heat will be generated. Traditional heating and cooling air conditioners do not provide means to utilize the heat, resulting in a lot of waste, and when the air conditioner is used, the indoor temperature drops, which will cause the outdoor temperature. increase and pollute the air environment. Many people are aware of this problem, and a variety of facilities and concepts have emerged from this, hoping to make full use of the heat and reduce waste and pollution. In the patent application whose application publication number is CN101813401A and the patent name is energy-saving air-conditioning and hot water triple supply system, an energy-saving air-conditioning and hot water triple supply system is disclosed. For heat exchangers, air heat exchangers, and air conditioner heat exchangers, the working medium inlet of the compressor is connected to the D port of the first four-way reversing valve, and the working medium outlet of the compressor is connected to the second four-way reversing valve. The A port of the reversing valve is connected, the B port of the first four-way reversing valve is connected with the D port of the second four-way reversing valve, and the B port of the second four-way reversing valve is connected with the hot water heat exchanger (4) One working fluid port is connected, the other working fluid port of the hot water heat exchanger (is connected to the A port of the first three-way reversing valve, and the C port of the second four-way reversing valve is connected to the first Only the C port of the three-way reversing valve is connected, the C port of the first four-way reversing valve is connected with a working fluid port of the air heat exchanger, and the A port of the first four-way reversing valve exchanges heat with the air conditioner One port of the working fluid of the air heat exchanger is connected to the port B of the first three-way reversing valve through the first expansion valve connected in parallel with the first one-way valve, and the other port of the air-conditioning heat exchanger The other working medium port is connected to the B port of the first three-way reversing valve through the second expansion valve connected in parallel with the second one-way valve. This energy-saving air-conditioning and hot water triple supply system can realize efficient and stable cooling throughout the year. The triple supply of heating, heating and sanitary hot water has a high comprehensive energy efficiency ratio; when cooling and producing hot water in summer, it can not only ensure high cooling efficiency, but also quickly heat sanitary hot water, overcoming the heat of an air conditioner. The disadvantage of contradictory energy efficiency ratio of water machine cooling and hot water heating speed, and solves the problem that the cooling efficiency of air-conditioning hot water machine decreases correspondingly with the increase of hot water temperature, and the unit becomes unstable; when heating in winter, Hot water production and heat storage can be carried out at the same time. Heating and hot water production do not affect each other, which solves the problem of insufficient heating when the temperature is low. The use of heat pipe heat exchangers not only improves the heat exchange efficiency, but also makes the unit The energy efficiency ratio is improved, which solves the problems of easy leakage of heat exchangers and water pollution, and overcomes the disadvantages of large resistance when multiple heat exchangers are connected in series. There are also many problems in this system, and its structure is relatively complicated, which leads to In addition, the manufacturing cost is increased, and its heat utilization rate is not high enough, and there are few usage modes, which leads to inflexible use.
