Multifunctional wide-working-condition efficient triple-generation air conditioner-water heater system

Abstract

The invention discloses a multifunctional wide-working-condition efficient triple-generation air conditioner-water heater system. The multifunctional wide-working-condition efficient triple-generationair conditioner-water heater system comprises a first refrigerating circuit with an air conditioning function and a second refrigerating circuit capable of supplying hot water; the first refrigerating circuit comprises a first compressor, a first four-way electromagnetic valve, an evaporative condenser, a first throttling element and an evaporator which are connected sequentially; the second refrigerating circuit comprises a second compressor, a second four-way electromagnetic valve, a shell-tube heat exchanger, a second throttling element and the evaporative condenser; and the evaporative condenser is provided with two independent refrigerant moving routes. According to the multifunctional wide-working-condition efficient triple-generation air conditioner-water heater system, an air conditioner and a water heater are separated into two independent systems by additionally arranging one compressor, and then the current conditions that refrigerant matching is difficult, and a control system is complex are overcome. A condenser of the air conditioner and an evaporator of the water heater are combined into one, two pipelines are connected in a bridging mode through integral fins, pipelines of the heat exchanger are staggered, the cold and hot complementation efficiency is improved, and functional categories of air source triple-generation new products are richer.

Description

technical field [0001] The invention relates to the technical field of heat exchange, and more specifically relates to a multi-functional, wide-working-condition and high-efficiency triple air-conditioning and water supply system. Background technique [0002] The air source triple supply unit is a kind of equipment that is driven by electricity and uses a vapor compression cycle. It can supply cooling and domestic hot water at the same time, heating and domestic hot water at the same time, and can also provide cooling, heating and domestic hot water separately. , He is different from "Cogeneration of cold, heat and electricity 'triple supply'". Combining air-conditioning condensation heat recovery technology and heat pump hot water heating technology, the coefficient of performance of heat pump hot water heating is much higher than that of electric heating or fuel heating. Therefore, triple supply units are an effective way to achieve energy saving, emission reduction and e...

AI Technical Summary

Problems solved by technology

[0008] When the modes of hot water heating, air conditioning, and hot water + air conditioning are switched, the refrigerant cannot meet the matching requirements of several heat exchangers, resulting in unbalanced and unstable systems, poor overall performance, and low efficiency.

[0009] Since there are many types of solenoid valves in the pipeline, there are many leakage points, which are prone to failure, and the electronic control is complex and difficult to maintain.

[0010] The inherent pipeline throttling and diverting devices cannot adapt to changes in various working conditions, and changes in working conditions will lead to worse performance of the whole machine
