Basic Operation Condition For Chiller

Jul 10, 2017

Industrial chiller in the course of operation will have a certain parameter for the user to refer to, can be displayed through the instrument. Can control and observe the industrial chiller in the operation of the various parameters, allowing users to determine whether the industrial chiller operating conditions are good, these parameters on the work of the equipment economy and security of a great impact on the equipment in the normal range The lower limit, the economic and reasonable operation, so as to achieve large cooling capacity, less energy consumption effect, greatly improve the chiller life.


1, evaporation temperature and evaporation pressure


The evaporative temperature of the industrial chiller can be reflected by the evaporation pressure indicated by the pressure gauge mounted on the end of the compressor suction valve. Evaporation temperature and evaporation pressure is determined according to the requirements of the refrigeration system, high can not meet the chiller cooling needs, too low will reduce the cooling capacity of the compressor, the operation of the economy is poor.


2, condensation temperature and condensation pressure


The condensing temperature of the refrigerant in the industrial chiller can be based on the gauge of the pressure gauge on the condenser. The determination of the condensation temperature is related to the temperature of the coolant, the flow rate and the form of the condenser. Under normal circumstances, the industrial chiller cooling temperature than the cooling water temperature 3-5 ℃ higher than the forced through the cooling air inlet temperature 10-15 ℃.


3, the compressor suction temperature


The inspiratory temperature of the compressor is the temperature of the refrigerant read from the thermometer in front of the compressor suction shutoff valve. In order to ensure that the industrial chiller heart - the safe operation of the compressor to prevent the phenomenon of liquid blow, the suction temperature is higher than the evaporation temperature. In the installation of the regenerator freon refrigeration industrial chiller, keep the suction temperature of 15 ℃ is appropriate, the ammonia cooling of the industrial chiller, inspiratory superheat generally take about 10 ℃.


4, the compressor exhaust temperature


The compressor exhaust temperature of the industrial chiller can be read from the thermometer on the exhaust line. It is related to the adiabatic index of the refrigerant, the compression ratio and the suction temperature. The higher the inspiratory temperature, the greater the compression ratio, the higher the exhaust temperature, and vice versa.


5, before the throttle supercooling temperature


Throttle liquid before cooling can be high cooling effect. The subcooling temperature can be measured from a thermometer on the liquid line on the throttle valve. Under normal circumstances it is cooler than the cooling water temperature of 1.5-3 ℃.


The above is the main operating parameters of the industrial chiller, the user through the observation and adjustment of the operating parameters of the industrial chiller operating conditions to make a judgment, but also allows the industrial chiller at the user's request under the most economical Reasonable operation, to help users reduce energy consumption, saving production costs.
