Q:How to deal with the liquid hammer phenomenon of compressor
Liquid hammer occurs mainly in piston compressors. As refrigerant liquid (or lubricating oil) is sucked in by compressor, it causes abnormal shock accident of compressor
Q:What is the function of the refrigeration compressor in the refrigeration system?
The compressor is the heart of the refrigeration system. It absorbs refrigerant gas from the suction pipe at low temperature and low pressure. It drives the piston to compress it through the motor, and then exhaust the refrigerant gas at high temperature and high pressure to the exhaust pipe
Q:What are the technical parameters of the compressor?
The power of the input motor is the electrical power consumed by the compressor Pel, the unit is kW. Electrical efficiency * is the ratio of the power to the electrical power of the isentropic compression theory, which is used to assess the degree of perfection of the input power of the motor
Q:What are the types of condensers?
The condenser is often used for the condensation of the two steam at the end of the multi effect evaporator to ensure the vacuum of the final effect evaporator
Q:What is the working principle of the BOG compressor?
The working principle of BOG compressor is to use the connecting rod to push the piston to move again and again, so that the gas can be pressurized and transported out
Q:What is the function and control of the evaporator and condenser of the air conditioner?
The condenser is like the boiling water on the stove
Q:What is the function of the hydraulic differential controller in the compressor?
When the oil pressure drops to insufficient to make the compressor work safely, it has not been restored to the set oil pressure value during the delay setting
Q:What about compressor overload protection?
Poor lubrication of compressor. Due to moisture and impurities in the refrigerating system too much, make the oil deterioration, or the refrigeration system return oil, compressor oil, will cause the compressor lubricating effect becomes poor, resulting in high temperature protection and compressor.
Q:What is the function of the air conditioning condenser?
The high pressure and high temperature refrigerant gas discharged from the compressor enters the condenser coil outside the chamber and is cooled by the airflow outside the fan (about 35 degree C) driven by the fan
Q:What is the working principle of the condenser?
Gases pass through a long tube (usually a solenoid) to dissipate heat into the air around them. Copper and other metals have a strong thermal conductivity and are often used to transport steam. In order to improve the efficiency of the condenser, heat transfer fins with excellent heat transfer performance are often used on the pipeline to increase the heat dissipation area to accelerate heat dissipation and to speed up air convection through the fan and take away the heat.
