Differences in capacitor size of air conditioner compressors

There are three capacitors on the air conditioner, which vary depending on the size and purpose of the air conditioner. These three are: axial flow fan starting capacitor, compressor starting capacitor, and indoor unit fan starting capacitor. The starting capacitance of the indoor unit fan has two micro-amplitudes or three micro-amplitudes. So how much capacitor should the air conditioner be equipped with? 1. The capacitor for 5 HP is usually 30-35UF, the capacitor for 2 HP is usually 50-60UF, and the capacitor for 3 HP is usually 60-65UF.   2. Different air conditioner brands use different capacitors. Generally, Changhong and Gree air conditioners use 35uF. Galanz air conditioners use 30uF. The difference in capacitance size of air conditioning compressors and compressor starting capacitors are all selected according to the compressor specifications and are not determined randomly. The capacitance of the air conditioner compressor plays a very important role in the operation of the entire body. Different types of capacitors can play different roles. If the capacitance of the machine is low, it will affect the normal use of the machine, so it plays a big role. If the capacity of the capacitor of the capacitor motor is too large or too small, the main and secondary windings will deviate from the 90-degree electrical angle. Although the motor can operate, the speed will decrease. If the capacitance is increased, the current flowing through the secondary winding will increase, and the heat generation will increase or even burn out. The difference in capacitance size of air-conditioning compressor The difference in capacitance size of air-conditioning compressor is: 1. The reason why the air-conditioning capacitance is too large: ①. The ambient temperature is higher, which increases the condensing pressure and the current will also increase ②. There is too much dust in the condenser , poor heat dissipation will also increase the condensation pressure and increase the current. ③. When the power supply voltage is low, the current will increase when the cooling power remains unchanged. ④. Air conditioning capacitor split-phase compressor, the capacitance changes. , will also increase the air conditioner current.   2. Reasons for the small capacitance of the air conditioner: ①. When the refrigerant leaks, the pressure in the system will be greatly reduced, the load of the compressor will be greatly reduced, and the current will be small. ② When the high and low pressure gases in the compressor will blow by. , the load of the compressor drops significantly, the current will be too small ③, the reciprocating compressor cylinder connecting rod is broken, and the rotary compressor shaft is disconnected, the current will also be too small.
