Abstract

The invention discloses a heat recovery multiple heat pump air-conditioning hot water machine and floor heating system, comprising a compressor, a three-way valve, an outdoor heat exchanger, an indoor heat exchanger, multiple electronic expansion valves, multiple branch pipes and multiple electromagnetic valves, wherein a high-pressure air pipe and a high-pressure liquid pipe of the compressor are respectively connected with a heating water tank and a water fluorine heat exchanger through the branch pipes, the expansion valves and the electromagnetic valves; and the water fluorine heat exchanger is connected with a floor heating pipe network through an expansion water tank and a water pump. According to the invention, the electromagnetic valves are controlled to be switched on or switched off by an electric control device to switch a low-pressure air pipe and the high-pressure air pipe to be communicated with the indoor heat exchanger, so that the indoor heat exchanger cools or heats; the electromagnetic valves are controlled to be switched on or switched off by the electric control device to switch the high-pressure air pipe to be communicated with the heating water tank, so that the heating water tank prepares hot water for life; and the electromagnetic valves are controlled to be switched on or switched off by the electric control device to switch the high-pressure air pipe to be communicated with the water fluorine heat exchanger, so that the water fluorine heat exchanger prepares hot water for floor heating. The invention can realize the aims of air-conditioning refrigeration, air-conditioning heating, preparation of hot water for life and floor heating simultaneously.

Description

technical field [0001] The invention relates to a heat recovery multi-connected heat pump air conditioner hot water machine plus floor heating system, which belongs to the technical field of air conditioner 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 or air conditioning heating + floor heating at the same time. In winter, some spaces need heating, and some spaces need hot water heating. At this time, the existing The multi-connected heat pump water heater system cannot be realized. At the same time, the existing multi-connected heat pump water...
