Overview of refrigeration compressor classification

The compressor is the core equipment in the refrigeration system. Only by converting electrical energy into mechanical work and compressing low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gas can the refrigeration cycle be ensured

The effect of insufficient refrigerant charge on the chiller

1. If the suction pressure and discharge pressure of the compressor are lower than the normal value, then you need to check to see if it is due to insufficient refrigerant charge.

Compressor operation in the heart of the refrigeration system in 2020

Compressor operation in the heart of the refrigeration system in 2020 A compressor is a fluid machine that raises low-pressure gas to high-pressure gas. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, thereby achieving compression-condensation (heat release) )-Expansion-evaporation (heat absorption) refrigeration cycle.

Reasons for poor cooling of air conditioners

The temperature in summer is high, and many of the owners' friends need air conditioning to spend the hot summer in the room. However, some owners often have such problems when using air conditioning in summer, such as poor air conditioning cooling. So, what are the reasons for poor air conditioning and cooling? How to solve the poor air conditioning and cooling? One of the reasons for poor air-conditioning and cooling: Freon is not enough (commonly known as fluoride deficiency) <img src="{{media url=&quot;magefan_blog/Reasons_for_poor_cooling_of_air_conditioners.jpg&quot;}}" alt="" />
