In the description of the present invention, if there are first and second described only for the purpose of distinguishing technical features, it is not understood that relative importance is indicated or implied or that the number of indicated technical features or the precedence of the indicated technical features is implicitly indicated or implied.

In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

The air conditioner is a complete set of system for purifying, cooling (or heating), humidifying (or dehumidifying) and the like air in a centralized or semi-centralized manner so as to provide environments required by life or production process standards, and generally comprises an air conditioning unit (host), air treatment end equipment, an air pipe system, a water system and a control system.

It can be understood that, at present, a household air conditioner is generally a split type wall-mounted air conditioner, and includes an outdoor unit and an indoor unit, the outdoor unit is installed outdoors, the indoor unit is hung on a wall, the outdoor unit is provided with a compressor and a condenser, the indoor unit is provided with an evaporator, the compressor, the condenser and the evaporator are connected through a pipeline, and a refrigerant flows in the pipeline.

In the related art, heat pump water heaters in the air conditioner market are increasingly demanded, air conditioner manufacturers begin to arrange brand new outdoor unit structures, and heat pump water heaters heat water by using high-temperature refrigerants of outdoor units to produce hot water, so that heat exchangers, water pumps and other components need to be added into the outdoor units. The development of a brand new outdoor unit not only relates to the design of the outdoor unit, but also relates to the reconstruction of a flow production line or the new construction of the flow production line, and a large amount of resources are required to be input, so that the economic benefit is low; and the existing outdoor unit structure scheme is abandoned, so that the development cost is not facilitated, and the production cost is higher.

Referring to fig. 1 to 3, an embodiment of the present invention provides a hydro module, which includes a mounting plate 100, a heat exchanger 210 connected to the mounting plate 100, a water pump 220, and an expansion tank 230, wherein the mounting plate 100 is pre-assembled with the heat exchanger 210, the water pump 220, and the expansion tank 230 as an integral structure. The mounting plate 100 is used to connect the outdoor unit 300, and the mounting plate 100 is a flat sheet metal member, and is directly fixed to the outdoor unit 300 in accordance with the shape of the outdoor unit 300, thereby facilitating assembly.

It can be understood that the heat exchanger 210 is a key component of the hydraulic module, hot water is produced through heat exchange, cold water is introduced into the heat exchanger 210 through the cold water pipe 211, high-temperature refrigerant gas is introduced through the refrigerant pipe 213, the high-temperature refrigerant gas and the cold water perform heat exchange in the heat exchanger 210, the produced hot water flows out from the hot water pipe 212, and the outer wall of the heat exchanger 210 is provided with an insulating layer to reduce heat loss; the hot water pipe 212 is connected to the water inlet end of the water pump 220, the hot water is driven by the water pump 220 to flow, the hot water is output from the output pipe 221 of the water pump 220, the exhaust valve 222 is arranged at the highest position of the output pipe 221, the expansion tank 230 is positioned above the output pipe 221, and the connecting pipe 231 of the expansion tank 230 is communicated with the output pipe 221.

It can be understood that the expansion tank is composed of four parts of a tank body, an air bag, a water inlet/outlet and an air supplementing port. The tank body is generally made of carbon steel, an anti-rust baking paint layer is arranged outside the tank body, the air bag is made of EPDM environment-friendly rubber, and pre-charging gas is filled between the air bag and the tank body. The working principle of the expansion tank is as follows: when the hot water pressure in the hydraulic module rises, part of the hot water enters the expansion tank, the nitrogen sealed in the tank is compressed, the volume of the compressed gas is reduced and the pressure of the compressed gas rises according to the Boyle's law of gas, and the water inlet is stopped until the pressure of the gas in the expansion tank is consistent with the pressure of the hot water. When the hot water loses pressure, the gas pressure in the expansion tank is greater than the pressure of the water, and the water in the expansion tank is extruded out and supplemented into the hydraulic module by the gas expansion. The expansion tank is used for buffering pressure change in the hydraulic module, so that impact of pressure on other parts is reduced, and stable operation is guaranteed.

It will be appreciated that when gas is present in the hydro module, the gas will climb up the conduit and eventually collect at the highest point (output conduit) of the hydro module, where the exhaust valve is typically mounted. The gas enters the valve cavity of the exhaust valve and is gathered at the upper part of the exhaust valve, the pressure rises along with the increase of the gas in the valve, when the gas pressure is higher than the system pressure, the gas can lead the water level in the valve cavity to fall, the buoy falls along with the water level, and the exhaust port is opened; after the gas is exhausted, the water level rises, the buoy also rises along with the water level, and the exhaust port is closed. In the same way, when negative pressure is generated in the system, the water level in the valve cavity is lowered, the exhaust port is opened, and the outside atmospheric pressure is higher than the system pressure, so that the atmosphere can enter the system through the exhaust port, and the negative pressure is prevented from being damaged. If the valve cap on the exhaust valve body is screwed down and the exhaust valve stops exhausting, the valve cap is usually in an open state.

It will be appreciated that the function of the heat exchanger 210 is to provide a heat exchange location, optionally a plate heat exchanger, which is a high efficiency heat exchanger formed by stacking a series of corrugated metal sheets. Thin rectangular channels are formed between the various plates through which heat is exchanged. The plate heat exchanger is an ideal device for heat exchange of liquid-liquid and liquid-vapor. The heat exchanger has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small occupied area, wide application, long service life and the like. Under the condition of the same pressure loss, the heat transfer coefficient of the heat exchanger is 3-5 times higher than that of the tubular heat exchanger, the occupied area of the heat exchanger is one third of that of the tubular heat exchanger, and the heat recovery rate can reach more than 90 percent.

The hydraulic module is fixedly connected to the outdoor unit 300 through the mounting plate 100, and during operation of the hydraulic module, the heat exchanger 210 introduces a high-temperature refrigerant output by a compressor of the outdoor unit 300 through the refrigerant pipe 213, and introduces cold water through the cold water pipe 211, and the high-temperature refrigerant and the cold water exchange heat in the heat exchanger 210 to prepare hot water and deliver the hot water through the water pump 220.
