Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments.
It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, in order to illustrate an embodiment of the noise reduction air conditioner of the present invention, as shown in fig. 1, the air conditioner includes an evaporator 100 of an indoor unit of an air conditioner, a condenser 200 of an outdoor unit of an air conditioner, an electronic expansion valve 300, a capillary tube 400, and a solenoid valve 500. The electronic expansion valve 300 has an inlet end 310 and an outlet end 320. The capillary tube 400 is disposed in series between the electronic expansion valve 300 and the evaporator 100. A first end of the capillary tube 400 is connected to the evaporator 100, and a second end is connected to the outlet end 320 of the electronic expansion valve 300; the inlet end 310 of the electronic expansion valve 300 is connected to the condenser 200. The solenoid valve 500 is connected in parallel to the capillary 400 through the parallel branch 600, and the solenoid valve 500 can control the connection and the closing of the parallel branch 600.
When the air conditioner is in a heating mode and is in a standby state, the electromagnetic valve 500 is closed, and the refrigerant flows between the indoor unit and the outdoor unit in sequence of passing through the evaporator 100 of the indoor unit, then passing through the capillary tube 400 and the electronic expansion valve 300, and then entering the condenser 200 of the outdoor unit. The capillary tube 400 shares part of pressure drop, plays the role of throttling and pressure reduction, reduces the front and back pressure difference of the electronic expansion valve 300, and weakens the noise generated by throttling.
When the air conditioner operates in a heating mode and heats, the electromagnetic valve 500 is opened, the parallel branch 600 is communicated, at the moment, the capillary 400 does not work, the capillary resistance of the capillary 400 is avoided by opening the electromagnetic valve 500, and the heating capacity is effectively improved.
When the air conditioner operates in a cooling mode, the solenoid valve 500 is closed, the flow direction of the refrigerant between the evaporator 100 and the condenser 200 is opposite to that in a heating mode, and the capillary tube 400 shares part of pressure drop, so that the front-back pressure difference of the electronic expansion valve 300 is reduced, and the noise generated by throttling is reduced.
According to the noise reduction air conditioner, the capillary tube 400 is additionally arranged behind the electronic expansion valve 300 to share partial pressure drop, so that the pressure difference between the front and the rear of the expansion valve is reduced, and the throttling noise is weakened; meanwhile, by arranging the parallel branch 600 and the electromagnetic valve 500 which are connected with the capillary 400 in parallel, when heating is performed, capillary resistance can be avoided by opening the electromagnetic valve 500, and the heating capacity of the air conditioner is effectively improved.
Further, the air conditioner further includes a muffler device (not shown) connected in series between the capillary tube 400 and the evaporator 100. The muffling device is preferably an intumescent muffler. The refrigerant noise is effectively weakened through the capillary tube 400, the rest refrigerant noise can still be transmitted to the expansion type silencer forwards through the connecting pipeline, the sound wave can be reflected at the sudden change position of the acoustic characteristic, at the moment, a part of the sound wave is reflected back to the sound source direction, only the minimum part of the sound wave is continuously transmitted forwards, and the noise is further weakened.
