Pool-type four-way three-valve conversion combination high-efficiency air-conditioning and hot water all-in-one machine and its working method

Abstract

The invention relates to a pool-type four-way three-valve conversion combination high-efficiency air-conditioning and hot water integrated machine and its working method. Next to the water tank, there are sequentially connected air compressors, four-way valves, heating and cooling air-conditioning water tanks containing heat transfer pipes, three one-way valves, throttle valves, cold and heat exchangers, and condensation and evaporation pipes. The output of the air compressors The port is connected to the first end of the condensing heating pipe of the water tank located in the heat preservation water tank, and the second end of the condensing heating pipe of the water tank is connected to the first valve port of the four-way valve. The present invention adopts a pool type four-way valve and three one-way valves The conversion combination can achieve the conversion in winter to improve heat absorption, and in summer, when the air conditioner is turned on, it can avoid heat absorption, reduce the temperature of the compressor, ensure normal operation, greatly improve the cost performance of the product, and improve the energy efficiency ratio, breaking through the winter The problem of low thermal efficiency is to truly achieve the purpose of energy saving.

[0004] At present, in the industry of air conditioning products, the combination of air conditioning and hot water is difficult to achieve high efficiency and energy saving. There have always been serious problems such as low cost performance, or high installation, maintenance and cleaning outside the wall. Low, in hot summer, when the water temperature is high, the compressor generates high temperature, which seriously affects the cooling effect. In winter, the thermal efficiency of the compressor cannot be improved, and the high temperature of hot water is avoided during cooling in summer, which affects the cooling effect and cost performance of the air conditioner. serious shortage of

In addition, it occupies a large area, and it is impossible to achieve the effect of integrating the host and an object into one, resulting in a problem of low cost performance. For the current high housing prices in the city, calculated at 10,000 yuan per square meter, the installation equipment occupies at least half a square meter. That is 5,000 yuan of floor space, which causes invisible expenses, greatly reduces the cost performance of the product, and makes it difficult to promote the market
