Air-conditioning water heater system

Abstract

The invention relates to an air-conditioning water heater system, which comprises an outdoor heat exchanger, a compressor, a four-way changeover valve and a condenser, wherein the outlet end of the compressor is connected with the condenser through the four-way changeover valve. The air-conditioning water heater system is characterized by also comprising an evaporator and a water heater, wherein the inlet end of the water heater is connected with the outlet end of the compressor; the outlet ends of the condenser and the water heater are connected with the inlet end of the evaporator and the inlet end of the outdoor heat exchanger respectively; the outlet end of the evaporator is connected with the inlet end of the compressor through the four-way changeover valve; the outlet end of the outdoor heat exchanger is respectively connected with the inlet end of the water heater and the inlet end of the compressor through a two-way changeover valve; and the inside of the condenser and the inside of the evaporator are provided with a loop structure respectively. The air-conditioning water heater system combines the conventional refrigeration system and the conventional hot-water productionsystem of an air-conditioning system, realizes refrigeration, heating and hot-water production, meets different cold and hot requirements, simultaneously saves the energy, and is convenient to control.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to an air-conditioning water heater system used in places with special requirements for cold and heat, such as hospitals and hotels. Background technique [0002] In public buildings such as hospitals, hotels, high-end office buildings and some high-end residences, the building energy consumption is about 6-7 times that of ordinary residences. This type of building needs both cold and heat. For example, in summer, it is generally necessary to produce a large amount of domestic hot water while cooling. It turns out that the usual practice is to separate the refrigeration system from the hot water system. As we all know, the electric chiller will generate a large amount of condensation heat in the process of producing chilled water. The condensation heat is about 1.3 times the cooling capacity. Ordinary Air-conditioning units often discharge this part of heat directly into the outdoor ai...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from the above that although the method of separately setting cold and heat sources in these buildings can meet different cooling and heating requirements, this method requires two sets of systems, which increases the cost and causes waste of energy, and the system is complicated and inconvenient to control
