Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the scope of the invention.
Examples
Referring to fig. 1, the multi-functional valve box for suppressing refrigerant flow noise of the present embodiment includes two check valves and a check solenoid valve, wherein one check valve and the check solenoid valve are connected in series and then connected in parallel with the other check valve.
Referring to fig. 2 and 3, the present embodiment of the present invention adopts the multifunctional valve box for suppressing flowing noise of refrigerant of fig. 1, and includes an outdoor unit, two indoor units and a water module, where the multifunctional valve box for suppressing flowing noise of refrigerant is installed on a main air pipe connected to the outdoor unit and the indoor units, the electronic expansion valves of the indoor units a and B are connected to a pipeline communicated with a liquid pipe of the outdoor unit, the outdoor unit and the water module are also communicated through an air pipe, and the electronic expansion valve of the water module is connected to a pipeline communicated with a liquid pipe of the outdoor unit. The system schematic diagram of the outdoor unit is shown in fig. 4, the system schematic diagram of the indoor unit is shown in fig. 5, and the system schematic diagram of the water module is shown in fig. 6, and since the outdoor unit, the indoor unit, and the water module adopted by the natural fluorine geothermal air-source heat pump of the embodiment are all the prior art, the working principles of the indoor unit, the outdoor unit, and the water module are not repeated.
Referring to fig. 2, when the water module heats, the electronic expansion valve of the water module is opened, the water module works normally, the refrigerant circulates between the water module and the outdoor unit along the arrow direction, the one-way solenoid valve of the valve box is closed at the moment, the air path for installing the one-way solenoid valve is not conducted, the independently arranged one-way valve is not conducted, and meanwhile, the electronic expansion valve of the indoor unit is closed, the refrigerant does not enter the indoor unit, so that the refrigerant flowing sound of the indoor unit of the air conditioner is eliminated.
Referring to fig. 3, when the water module is defrosted, the electronic expansion valve of the water module operates at defrosting opening, the refrigerant circulates between the water module and the outdoor unit along the arrow direction, the one-way solenoid valve of the valve box is closed at the moment, the air path for installing the one-way solenoid valve is not conducted, the independently arranged one-way valve is not conducted, and meanwhile, the electronic expansion valve of the indoor unit of the air conditioner is closed, so that the refrigerant does not enter the indoor unit, and the flowing sound of the refrigerant in the indoor unit of the.
No matter when the air conditioner is heated or defrosted by the natural fluorine ground water air source heat pump water module, the two sides of the air conditioner are closed by the indoor unit electronic expansion valve and the one-way electromagnetic valve, so that the refrigerant does not flow through the indoor unit, the flowing sound of the refrigerant of the air conditioner is eliminated, the design structure is simple, the original air conditioner outdoor unit system does not need to be changed, and the cost is saved.
