- Summary of chillers
   Chiller is the heart of the central air conditioning system, the correct choice of chillers, not only the success of engineering design guarantee, while the system also has a long-term impact. Therefore, the selection of chillers is an important task.
   1. Consider the considerations for chillers:
   The use of the building.
   Performance and characteristics of various chillers.
   Local water sources (including water and water quality), power and heat sources (including the type of heat, nature and grade).
   Distribution of Cold Load (Heat Load) of Air Conditioning in Buildings.
   Initial investment and operating costs.
   Limits for freon refrigerant and the possibility of using alternative refrigerants.
   2. Selection of chillers Note:
   After taking full account of the above factors, the choice of chillers, should also note the following:
   For large-scale centralized air-conditioning system of cold source, should choose a compact, small footprint and the compressor, motor, condenser, evaporator and automatic control components are assembled in the same frame on the chiller. For small all-air conditioning systems, direct evaporative compression condensers should be used.
   Where there is a suitable heat source, such as waste heat or waste heat or other places or lack of electricity, should adopt the absorption chillers.
