In the course of operation, there are some parameters for the reference of the users, and can be displayed by the relevant instruments. Can control and observe industrial chiller parameters at run time, users can judge the operating condition of industrial chiller is good, great economic effect of these parameters on equipment work and the safety of the equipment in the normal range within the upper and lower limits, economic and reasonable operation, so as to achieve the refrigeration capacity, low energy consumption effect, greatly improve the life of water cooling machine. Here are some of the operating parameters of industrial chillers for everyone to understand.
1, evaporation temperature and evaporation pressure
The evaporation temperature of the industrial chiller can be reflected by the evaporation pressure indicated by the pressure gauge installed on the suction end of the compressor. The evaporation temperature and evaporation pressure are determined according to the requirements of the refrigeration system, the high side can not meet the needs of the cooling water cooler, too low will reduce the cooling capacity of the compressor, the economy is poor.
2, condensation temperature and condensation pressure
The condensing temperature of the refrigerant in the industrial chiller can be measured according to the pressure gauge on the condenser. The determination of condensation temperature is related to the coolant temperature, flow rate and the form of condenser. Under normal circumstances, the condensation temperature of the industrial chiller is higher than that of the cooling water, which is 3-5 DEG C, which is higher than the inlet temperature of the forced cooling air 10-15.
3, the compressor suction temperature
The suction temperature of the compressor is the refrigerant temperature from the thermometer in front of the suction valve of the compressor. In order to ensure the safe operation of the industrial chiller heart - compressor, to prevent the phenomenon of liquid hammer, the suction temperature is higher than the evaporation temperature. In the establishment of the regenerator of freon refrigeration industrial chillers, to maintain the suction temperature of 15 degrees Celsius is suitable for ammonia refrigeration industrial chillers, suction superheat generally take about 10 degrees celsius.
4, compressor exhaust temperature
The compressor exhaust temperature of an industrial chiller can be read from the thermometer on the exhaust line. It is related to the adiabatic index, compression ratio and temperature of the refrigerant. The higher the suction temperature, the greater the compression ratio, the higher the exhaust temperature, and vice versa.
5, throttle before the supercooling temperature
Liquid cooling before throttling can be used for high refrigeration. The supercooling temperature can be measured from the thermometer on the liquid pipe before the throttle valve. Under normal circumstances it is cooler than the cooling water of the water temperature of 1.5-3.
The above is the main operating parameters of industrial chiller, the user operating condition of industrial cooling water machine a judgment through observation and adjustment of the operating parameters, can also make industrial chillers are the most economical and reasonable operation according to user requirement, help users to reduce energy consumption, save the cost of production.
