water-cooled chillerSelection:Choosing the right chiller unit is not only a guarantee of successful engineering design, but also has a long-term impact on the operation of the system. Therefore, the selection of chiller units is an important task.

Considerations for choosing a chiller unit:

The selection of chiller units should be based on local energy conditions, water sources and quality conditions, chiller unit capacity, operational economy, etc., and a cost-effective chiller selection method should be determined:

For the cold source of large centralized air conditioning systems, it is advisable to choose a chiller unit with a compact structure, small footprint, and compressor, motor, condenser, evaporator, and self-control components all assembled on the same frame. For small all air conditioning systems, it is advisable to use direct evaporative compression condensing units.

2. For places with suitable heat sources, especially those with waste heat or electricity shortages, absorption chillers should be used.

3. Generally, 2-4 refrigeration units are recommended, with 2 units for small and medium-sized scale, 3 units for larger scale, and 4 units for extra large scale. The possibility of mutual backup and switching between units should be considered. A combination scheme of different types and capacities of units can be used in the same computer room to save energy consumption. At least one unit with a high degree of automation, good regulation performance, and the ability to operate efficiently under partial load should be selected for parallel operation. When choosing a piston type chiller, it is advisable to prioritize the use of multi head automatic control chillers.

When choosing an electrically driven chiller unit, centrifugal type should be selected when the cooling capacity of a single air conditioner is greater than 1163kW; When the power is between 582 and 1163kW, centrifugal or screw type should be selected; When the power is less than 582kW, it is advisable to use a piston type.

The coefficient of performance (COP) of electric driven refrigeration machines is higher than that of absorption refrigeration machines, with the former being more than twice as high as the latter. The order of energy consumption from low to high is: centrifugal, screw, piston, and absorption (screw type is ranked before centrifugal type in foreign units). But each type of unit has its own characteristics, and its strengths should be applied.

When choosing a refrigeration unit, consideration should be given to its environmental pollution: firstly, noise and vibration should meet the requirements of the surrounding environment; The second issue is the degree of harm caused by refrigerant CFCs to the atmospheric ozone layer and the magnitude of their greenhouse effect, with particular attention paid to the ban schedule for CFCs. Absorption refrigeration machines have significant advantages in preventing CFCs pollution.

7. If there is no dedicated computer room location or air conditioning renovation and installation project, modular chillers can be considered.
