Technical Field

The utility model relates to a heating leads to air conditioning system, specifically relates to a three pipeline air conditioner auxiliary module that is used for three pipeline air conditioner auxiliary module to fall the device of making an uproar and has this device of making an uproar.

Background

Currently, one type of air conditioning system may include one outdoor unit (referred to as an outdoor unit) and a plurality of indoor units (referred to as indoor units) connected together by three types of pipes, which are composed of a high pressure gas pipe, a low pressure gas pipe, and a liquid pipe. This type of air conditioning system is therefore also called a "three-circuit" air conditioning system, which is capable of operating in both cooling mode and heating mode, i.e. when a part of the indoor units are operating in cooling mode, another part of the indoor units are capable of operating in heating mode, such as the air conditioner disclosed in japanese patent JP2804527B 2.

In order to realize a mixed mode in which different indoor units of a three-pipe air conditioning system perform cooling and heating simultaneously, a three-pipe air conditioning auxiliary module (also referred to as a "valve box") is arranged between the outdoor unit and each indoor unit and used for controlling the flow rate, the flow direction and the performance feedback of a refrigerant in real time. Such valve boxes usually comprise a piping system and an electronic control system, both of which are separate components, assembled together in some way, for example by means of screws or hooks. The chinese utility model patent CN206131227U discloses a three-pipe valve box for air conditioner with cooling and heating simultaneously, which comprises a valve body and an electric cabinet fixed with the valve body. A high-pressure gas passage, a low-pressure gas passage and a liquid passage are provided in the valve body, and different-function electronic devices such as a solenoid valve and an electronic expansion valve are disposed on these passages. The valve body is also provided with an outdoor unit side high-pressure air pipe connector, an outdoor unit side low-pressure air pipe connector, an outdoor unit side liquid pipe connector, an indoor unit side gas pipe connector and an indoor unit side liquid pipe connector. The outdoor unit side high-pressure air pipe interface is communicated with a high-pressure air channel; the outdoor unit side low-pressure air pipe interface is communicated with the low-pressure air pipe channel; the indoor machine side air pipe connector is selectively communicated with a high-pressure air channel or a low-pressure air channel through a four-way valve; the liquid pipe interfaces of the indoor machine side and the outdoor machine side are respectively communicated with the liquid channel. The valve body typically includes a housing that houses all of the plumbing and electronics. All the ducts are arranged in the lower part of the housing. A partition is also provided within the housing above all of the tubes to enclose all of the tubes in a lower portion of the housing, while the electronics pass through the partition from below and are exposed above the partition. The top of the housing is provided with a cover plate to form a semi-enclosed space around the electronic device.

The environment of use of the three-duct air conditioning auxiliary module is usually located near the indoor unit of the air conditioner. Under the working state, the pipelines in the three-pipeline air conditioner auxiliary module can generate disordered vibration or cavity abnormal sound in the circulation process of a refrigerant, so that noise is generated. When the three-pipeline air conditioner auxiliary module vibrates due to external force, the noise in the three-pipeline air conditioner auxiliary module is strengthened. In addition, in a normal working state, the solenoid valve is frequently activated or switched in function according to user requirements or special working conditions, so that a very short noise or vibration is generated. Because the electronic devices such as the electromagnetic valve are in the semi-closed space, the noise generated in the three-pipeline air-conditioning auxiliary module can be obviously transmitted out and spread outwards through the semi-closed space, and the noise can seriously affect the use experience of the user on the air-conditioning system.

In addition, the three-pipeline air-conditioning auxiliary module needs to be installed in different spaces, that is, the installation space of the three-pipeline air-conditioning auxiliary module may be narrow, or after the three-pipeline air-conditioning auxiliary module is placed in the connection direction of the refrigerant inlet and outlet pipes, the electric cabinet needs to be installed and fixed on the outer side of the three-pipeline air-conditioning auxiliary module, so that the fixed state of the electric cabinet needs to be normally switched between the front side and the rear side of the three-pipeline air-conditioning auxiliary module. Meanwhile, for the convenience of maintenance of electronic devices (e.g., solenoid valves) or other lines, it is required that devices located in a space above the electronic devices can be opened without disassembling the machine, and in view of a small installation space, the operation generally needs to be performed in a horizontal direction.
