Abstract

The invention relates to a multiple heat pump air-conditioning water heater which comprises a compressor, three-way valves, an outdoor heat exchanger, an indoor heat exchanger, a plurality of electronic expansion valves, a branch pipe and an electromagnetic valve; one end of each three-way valve is communicated with a high-pressure air pipe of the compressor, and the other end of the three-way valve is communicated with the outdoor heat exchanger, the electronic expansion valves, the branch pipe and the indoor heat exchanger in sequence; the high-pressure air pipe and a high-pressure liquid pipe of the compressor are respectively connected with the branch pipe, the electronic expansion valves, the electromagnetic valve and a water-fluoride heat exchanger; the water-fluoride heat exchanger is connected with a water storage tank through a water pump; the three-way valves are two in quantity, and the two three-way valves are connected mutually in parallel and form a connecting loop together with the compressor. In the invention, an electric control device controls on or off switch of the electromagnetic valve and the communication of a low-pressure air pipe, the high-pressure air pipe and the indoor heat exchanger so that the indoor heat exchanger can refrigerate or heat; the electric control device controls the electromagnetic valve to be powered on or off so that the high-pressure air pipe and the water-fluoride heat exchanger are powered on or off and the water-fluoride heat exchanger can heat water, thereby realizing the simultaneous operation of three basic modes: namely, air-conditioning refrigeration, air-conditioning heating and hot water production.

Description

technical field [0001] The invention relates to a multi-connected heat pump air-conditioning water heater, which belongs to the technical field of air-conditioning environmental protection and energy saving. Background technique [0002] The existing multi-connected heat pump water heater is a kind of heat recovery air conditioner, but it has only four basic operation modes, that is, air conditioning cooling, air conditioning heating, hot water heating, air conditioning cooling + hot water heating. There are limitations in practical applications, and it is impossible to realize the functions of air conditioning heating + hot water heating at the same time. In winter, some spaces need heating, and some spaces need hot water heating. At this time, the existing multi-connected heat pump water heater system cannot be achieved. The existing three-pipe heat recovery multi-connection unit can realize the simultaneous cooling and heating functions of air conditioning. It is also a ...
