It is composed of multiple modular chiller units in parallel. Using microcomputer to coordinate and control multi-loop work, each compressor can independently adjust energy. Modular unit can be composed of up to 13 units. Modular chiller is equipped with a computer monitoring system to control the entire unit according to air conditioning. The size of the load, regularly start and stop each compressor or change high-speed operation to low-speed operation, including each independent refrigeration system and the entire machine operation.
Advantages:
1. According to the change of cooling load, adjust the number of running modules at any time, so that the output cooling capacity can be optimally matched with the air conditioning load and energy consumption can be saved.
2. Multiple compressors working in parallel are guaranteed.
3, light weight, small size, saving construction area;
4. The modular combination provides the maximum backup capacity for the refrigeration system, and it is very simple and easy to expand the unit capacity.
Disadvantages:
1. High water quality requirements, once fouling and blocking, it will affect the heat transfer of the condenser and evaporator.
2. High cost, many parts, many wearing parts, high maintenance cost.
3, the compression ratio is low, the single cooling capacity is small
4. Poor adjustment performance under partial load of single head, no stepless adjustment
5. The weight index per unit cooling capacity is relatively large.
