Four-circulation separation heat storage type hot water air conditioner

Abstract

The invention discloses a four-circulation separation heat storage type hot water air conditioner. The air conditioner is characterized in that a refrigerant circuit particularly comprises a three-way valve, a four-way valve, three check valves and two throttlers; according to a circuit connection mode, a compressor outlet is connected with the three-way valve, a first outlet and a second outlet of the three-way valve are connected with a hot water condensation heat exchanger and an inlet of the four-way valve correspondingly; a second connector, a third connector and a fourth connector of the four-way valve are connected with an outdoor air heat exchanger, an indoor air heat exchanger and a gas-liquid separator correspondingly; a lower connector of the outdoor air heat exchanger are in parallel connection with an outlet of the first check valve and an inlet of the second check valve; the second check valve and an outlet of the hot water condensation heat exchanger enter a liquid storage tank together and are connected with the first throttler sequentially; an outlet of the second check valve, an outlet of the second throttler, an inlet of the first check valve and an inlet of the third check valve are connected mutually; the outlet of the second throttler as well as the inlet of the third check valve and a lower connector of the indoor air heat exchanger are connected mutually; the four circulations of cooling air, cold air, hot water and hot air are conducted; and the hot water condensation heat exchanger and a heat storage water tank are connected through a circulation waterway, and a circulation water pump and an auxiliary heater are arranged. The four-circulation separation heat storage type hot water air conditioner is simple and reliable in structure, low in cost, good in energy saving effect and good in market prospect.

Description

technical field [0001] The invention relates to the technical fields of refrigeration air conditioners, heat pump water heaters and energy saving. Background technique [0002] Existing heating and cooling air conditioners are only useful in summer and winter, and are generally idle in spring and autumn, resulting in seasonal waste of equipment and funds. The heat pump water heater, which utilizes the condensed heat of the compressed refrigeration cycle of the air conditioner to make hot water, can replace the household electric water heater, which can save 70% of electricity. The energy saving effect is obvious, and the market potential is huge. However, currently commercially available air source heat pump water heaters only have a single function of making hot water, and cannot realize the comprehensive utilization of cold and heat. However, there are many existing patented technologies involving multifunctional heat pumps. The structure of the refrigerant circulation lo...

Problems solved by technology

However, currently commercially available air source heat pump water heaters only have a single function of heating water, and cannot realize the comprehensive utilization of cold and heat.

However, there are many existing patented technologies involving multifunctional heat pumps. The structure of the refrigerant circulation loop is complex, the valves inevitably leak, the failure rate is high, and the reliability is poor. So far, they have not been marketed; Research on machine use, declared and authorized a number of related patent technologies, such as: a double-effect four-season energy-saving heating and cooling air-conditioning hot water three-purpose machine (patent number: CN 00264455.x), a four-season energy-saving heating and cooling air-conditioning hot water three-purpose Machine (patent number: CN 02116049.X), air source heat pump water heater with diversion sleeve heat exchanger storage tank (patent number: CN 200510053315.3), heat pump hot water unit with water circulation heat exchange circuit (patent number : CN 200610085913.3), a dual heat source heat pump water heater with a very simple refrigeration circuit (CN 200910181300.3), a mutual defrosting method for an air source heat pump water heater and a five-cycle dual heat source heat pump water heater (CN 201010211846.1), an air source for mutual defrosting Heat pump water heaters and five-cycle dual heat source heat pump water heaters (CN 201020240385.6), parallel-connected mutual-aid defrosting air source heat pump water heaters (CN 201010272024.4), self-built natural circulation flow heat exchange compact heating and cooling air-conditioning and hot water three-purpose machine (CN 201010568937.0,) , a four-season energy-saving heating and cooling air-conditioning and hot water three-purpose machine (CN 02116049.X, CN 02220342.7), two-source multifunctional heat pump (CN 201110202512.2), etc., still think that there are too many valves in the refrigerant circuit, and the refrigerant is in different heat exchangers Uneven storage will affect the efficiency of the unit; develop a multi-functional hot water air conditioner with simple structure, reliable operation, and superior performance, which has the functions of refrigerating air to make hot water, heat pump circulating hot water, refrigerating air and heating, and hopes to promote it to the market as soon as possible. The market is still worthy of continuous research
