For the screw chiller currently used by users, in order to cope with the load change of the air conditioning system during operation, the outlet water temperature of the unit still needs to maintain certain requirements. The screw chiller realizes the application requirements through effective adjustment. Among them, the screw chiller The control system of the unit first needs to detect the outlet water temperature of the unit, and compare it with the set value, and issue an energy adjustment command, and when the cooling capacity of the unit increases or decreases, it should be observed and understood in time.
When users choose a screw chiller, please give priority to models with a relatively flat efficiency curve. At the same time, the load adjustment range of the chiller should be considered when designing and selecting. Multi-head screw chillers have excellent load performance and can be selected according to the situation. In order to effectively ensure the cleanliness of the surrounding environment of the screw chiller, it is necessary to check the installation device of the equipment on time, check whether the function of the control center is abnormal, the operating status of the compressor, etc., and check the water system and heat exchange of the chiller. effect, the refrigerant filling amount of the unit.
Its screw chiller is the same as the piston chiller compressor. During the operation, the energy adjustment of the equipment is also adjusted by effectively adjusting the exhaust volume to adjust the amount of cold water. When used, it mainly realizes the energy adjustment mechanism of the compressor, so the screw chiller The energy adjustment of multi-units is realized by increasing or decreasing the number of compressors, and the control program can set the loading sequence of each compressor. Therefore, the multi-head screw chiller has been obtained in engineering practice because of its excellent part-load performance. widely used.
