Product Application

What role does the sensor play in the air compressor?

The compressor (compressor), as the heart of the refrigeration system, is a driven fluid machine that lifts low-pressure gas into high-pressure gas. The low-temperature and low-pressure refrigerant gas sucked from the suction pipe is compressed by the rotation of the motor to discharge the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. Thus, a refrigeration cycle of compression → condensation (exotherm) → expansion → evaporation (heat absorption) is realized. The compressor is divided into piston compressor, screw compressor, centrifugal compressor, linear compressor and so on.

During the work, the actual responsibility of the compressor is to increase the pressure and increase the state of the suction pressure to the state of the exhaust pressure. Compression ratio is a technical expression of pressure difference, which means the absolute pressure on the high pressure side divided by the absolute pressure on the low pressure side. The compression ratio must be calculated using an absolute pressure value. In order to avoid making the calculated value of the compression ratio negative, the absolute pressure must be used instead of the gauge pressure when calculating the pressure ratio. It makes sense to use an absolute pressure value to make the compression ratio calculation a positive value.

Large central air conditioning, refrigeration equipment, in order to achieve automatic control of the machine, the lowest energy consumption ratio, the operation of the equipment needs to be fully monitored, such as temperature, refrigeration medium pressure.
 The pressure sensor mainly measures the pressure of the refrigerating medium online on the refrigerating equipment, and transmits the pressure to the control system of the main machine in the form of electrical signals, so as to reflect the compression operation state of the equipment, to realize the automatic control of the product, and to reflect the consumption of the equipment as soon as possible.
