The main control parameters of Headpower Marine Seawater Cooling Screw Water Chillers are refrigeration performance coefficient, rated cooling capacity, input power and refrigerant type, etc. The selection of chillers should be considered according to the cooling load and use. For the refrigeration system with low load and long working time, multi-head piston compressor unit or screw compressor unit should be selected to facilitate adjustment and energy saving.
When selecting Headpower Marine Seawater Cooling Screw Water Chillers, give priority to units with higher performance coefficient value. According to statistics, the operating time of the general chiller is less than 1/4 of the total operating time under 100% load.
When selecting Headpower Marine Seawater Cooling Screw Water Chillers, attention should be paid to the conditions of nominal working conditions. The actual cooling capacity of the chiller is related to the following factors:
A) cold water outlet temperature and flow rate;
B) Inlet temperature, flow rate and fouling coefficient of cooling water.
When selecting the chiller, attention should be paid to the normal working range of this type of unit, mainly because the current limit of the main motor is the current value of shaft power under nominal working conditions.
