Heat-recovery air energy air conditioner water heater

Abstract

The invention discloses a heat-recovery air energy air conditioner water heater which comprises a controller, an evaporator, a compressor and a condenser, wherein the evaporator, the compressor and the condenser are successively connected to form a sealed refrigerating fluid circulation loop. The heat-recovery air energy air conditioner water heater is characterized by also comprising a solenoid operated four-way valve, a pressure-bearing water tank, a solenoid operated two-way valve, a liquid valve, an air valve, a one-way expansion valve and a hot water capillary, wherein a heat exchange tube is arranged in the pressure-bearing water tank, the solenoid operated four-way valve is respectively connected with the heat exchange tube of the pressure-bearing water tank, the condenser, the compressor and the evaporator through pipelines, two loops are connected in parallel between a compressor exhaust tube and the solenoid operated four-way valve, one loop is formed by sequentially connecting the compressor, the air valve, the heat exchange tube of the pressure-bearing water tank, the liquid valve and the solenoid operated four-way valve, and the other loop is formed by sequentially connecting the compressor, the solenoid operated two-way valve and the solenoid operated four-way valve; and the outlet of the condenser is provided with two loops, wherein one loop is formed by sequentiaaly connecting the condenser, the one-way expansion valve, the liquid valve, the evaporator, the air valve and the solenoid operated four-way valve are successively connected, and the other loop is formed by sequentially connecting the condenser, the hot water capillary, the solenoid operated two-way valve and the solenoid operated four-way valve. Thus, the invention has the advantages of high efficiency, energy saving, environment protection and safety.

Description

technical field [0001] The invention relates to a water heater, in particular to a heat recovery type air-energy air-conditioning water heater, which is mainly used in households and commercial places where the air-conditioning utilization rate is high and the heat energy release is large. The gas compressed into high temperature and high pressure condenses and releases heat to the copper tube in the water tank, and at the same time, the air energy air conditioner water heater that produces hot water through heat exchange with water. Background technique [0002] At present, various heat recovery air-conditioning water heaters have appeared on the market. In terms of performance, they cannot make hot water alone in winter, and need to add auxiliary heat pump heating next to the water tank, which increases equipment cost and use area. From the control circuit In other words, the wiring is complicated, there are many relay protections, many thread ends, the maintenance is diff...

[0002] At present, various heat recovery air-conditioning water heaters have appeared on the market. In terms of performance, they cannot make hot water alone in winter, and need to add auxiliary heat pump heating next to the water tank, which increases equipment cost and use area. From the control circuit In other words, the wiring is complicated, there are many relay protections, many thread ends, the maintenance is difficult, the production labor cost is large, and the management cost is high. Because of its simple function, it cannot make hot water in winter, causing many changes to the user.
