Problems solved by technology

[0003] In order to overcome the deficiencies of the existing multifunctional hot water air conditioner and improve the reliability of the system, the present invention proposes a practical multifunctional hot water air conditioner, which can realize cooling air, cooling and hot water production in summer, and heating air and hot water supply in winter. There are two ways of water heating, absorbing outdoor air in spring and autumn to make hot water, solving the problem of multi-circuit refrigerant flow, and enabling the system to automatically adjust the amount of refrigerant throttling according to seasonal temperature changes, and the cost is relatively cheap. Reverse defrosting of hot water heat can solve the problem of incomplete defrosting and normal operation of general heating and cooling air conditioners in winter

Abstract

The invention discloses a practical multifunctional water-heating air-conditioner, characterized by comprising a three-way valve, a four-way valve, and a multi-loop throttle mechanism. The multifunctional water-heating air-conditioner realizes circulation of four functions of refrigeration, refrigeration and water heating, water heating, and hot gas production by using a compressor, an indoor air heat exchanger, an outdoor air heat exchanger, and a water-heating heat exchanger. The multi-loop throttle mechanism comprises a rectification circuit formed by four one-way valves, a main throttling element, and an auxiliary throttling element. When the throttling elements are thermostatic expansion valves, a thermal bulb is installed on a pipeline toward a compressor direction near the outlet of the outdoor air heat exchanger. By using quantity of heat of hot water and the bypass of a bypass defrosting solenoid valve, a refrigerating fluid defrosts. An exhaust capillary tube of a solenoid pilot valve of a three-way valve is communicated with a system low-pressure pipeline. A micro solenoid valve may be installed on the high-pressure capillary of the solenoid pilot valve of the four-way valve, the high-pressure capillary being connected with the exhaust pipe of the compressor, and the micro solenoid valve is shut down after switchover of the four-way valve. The refrigerating fluid of a circulation loop can be maintained to be stable in multifunctional circulation, and the water-heating air-conditioner has no inner leakage, and is high in efficiency.

Description

technical field [0001] The invention relates to the technical field of air conditioners / heat pump water heaters. Background technique [0002] The Yangtze River Basin is a humid zone with hot summer, cold winter and spring, and basically needs air conditioning, heating, and domestic hot water. But current heating and cooling air conditioners cannot provide hot water; air energy water heaters have a single function and can only provide domestic hot water; although the applicant has applied for multiple related patents. For example, simple, efficient and reliable heating and cooling air-conditioning water heaters (201010215579.5, 201020245130.9), a dual heat source heat pump water heater with a very simple refrigeration circuit (200910181300.3), a mutual defrosting method for air source heat pump water heaters and a five-cycle dual heat source heat pump water heater ( 201010211846.1), mutual defrosting air source heat pump water heater and five-cycle dual heat source heat pum...
