Description

Low-noise commercial air conditioner outdoor unit motor

Technical Field

The utility model relates to the technical field of air conditioner outdoor units, in particular to a low-noise commercial air conditioner outdoor unit motor.

Background

As is well known, an air conditioner, i.e. an air conditioner, which adjusts temperature, humidity, and a wall-mounted air conditioner, is a unit for providing a space area (generally, a closed space) with a process air temperature variation. The function of the device is to adjust the parameters of temperature, humidity, cleanliness, air flow rate and the like of the air in the room (or the closed space or the area) so as to meet the requirements of human comfort or the technological process.

The compressor compresses the gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, and then sends the gaseous refrigerant to the condenser (outdoor unit) to dissipate heat and then become normal-temperature and high-pressure liquid refrigerant, so that the outdoor unit blows out hot air, then the hot air enters the capillary tube and enters the evaporator (indoor unit), and as the space of the refrigerant suddenly increases after the refrigerant reaches the evaporator from the capillary tube, the pressure is reduced, the liquid refrigerant is vaporized and becomes gaseous low-temperature refrigerant, so that a large amount of heat is absorbed, the evaporator is cooled, and the indoor air is blown out from the evaporator by the fan of the indoor unit, so that the indoor unit blows out cold air; the water vapor in the air is condensed into water drops after encountering a cold evaporator and flows out along a water pipe, which is why the air conditioner can produce water, and a component called a four-way valve is arranged during heating, so that the flowing direction of the refrigerant is opposite to that of the refrigerant during cooling, and cold air is blown out of the air conditioner during heating, hot air is blown out of the air conditioner, and the principle of heat removal and heat absorption during vaporization (from liquid to gas) is adopted during liquefaction (from gas to liquid) learned in the physics of the junior middle school.

The existing outdoor unit has high noise, the noise generated by the outdoor unit is caused by vibration of the fan and sound of air flow, and the most main reason is the noise generated by friction between the air flow generated by the fan and the outdoor unit casing.
