Requirements for the use of freezing oil

Requirements for the use of freezing oil Due to the different use occasions and refrigerants, the choice of refrigeration oil for refrigeration equipment is also different. The requirements for freezing oil< are as follows: 1. Freezing point: The temperature at which the freezing oil is cooled to stop flowing under the experimental conditions is called the freezing point. The freezing point of the refrigeration oil used in refrigeration equipment should be as low as possible (such as R22 compressors

The impact of compressed air not up to the standard on the PCB industry

Example: A certain company uses an imported high-speed drilling machine, but the current drilling rate is only one-third of the rated rate. What is the reason? The company’s production department often complains about water in the gas equipment, which affects production. What is the reason?

Classification, principle and use of refrigeration compressors

Classification, principle and use of refrigeration compressors<br></br> The function of refrigeration compressor:<br></br> The refrigeration compressor is the "heart" of the refrigeration system. It absorbs the refrigerant vapor from the evaporator, increases the pressure and discharges it to the condenser, so that the refrigerant circulates in the system. Can be used in refrigeration systems and heat pump systems

How to select the thermal expansion valve？

1. The role and classification of expansion valves<br></br> Expansion valve is an important part of refrigeration system, generally installed between liquid storage cylinder and evaporator. The expansion valve causes the medium temperature and high pressure liquid refrigerant to become low temperature and low pressure wet vapor through its throttling, and then the refrigerant absorbs heat in the evaporator to achieve the cooling effect.

The correct use of the central air-conditioning switch, have you done it right

In daily life, when we use the air conditioner, we may frequently turn on or turn off the air conditioner. As everyone knows, this situation will directly affect the service life of the air conditioner;

How good is the air conditioning dehumidification

Nowadays, the temperature of some air conditioners is set actively by the manufacturer during dehumidification. Under the dehumidification method of this type of air conditioner, the control circuit will first check the room temperature, and then set the operating temperature policy value. The setting value of the factory plan is usually the policy value of the operation arrival It is 2 degrees lower than the room temperature. If the setting is too high, the dehumidification effect is not significant. In order to prevent overheating and lowering the room temperature during dehumidification, this set value is usually judged. At this time, we do not need to set the temperature, just open the air conditioning dehumidification function.<img src="{{media url=&quot;How_good_is_the_air_conditioning_dehumidification.jpg&quot;}}" alt="" />

The structure of the central air conditioner is relatively complicated

The structure of the central air conditioner is relatively complicated. During use, the compressor noise is often accompanied by vibration. The vibration will increase the decibel of the noise, and the two affect each other. However, if the sound of vibra器2䀀
