Therefore, the user also needs to set the design redundancy of the air conditioner, and the cold load of the air conditioner exceeds the cold load of the building by a certain proportion, so that the central air conditioner can meet the cold load requirement of the building and the capacity of the central air conditioner is not wasted too much. For example, the range of air conditioner design redundancy can be set to 1.1-1.2, which means that the range of cooling load can be designed to be 1.1-1.2 times of the building's cooling load.

The design parameters (design flow, design lift, design power and design efficiency) of the matched chilled water pump can be calculated according to the performance parameters of the water chilling unit combination. The principle of automatically matching the chilled water pump in the proper range is as follows:
1) the water flow of each chilled water pump is slightly larger than the calculated design flow, and the lift of each chilled water pump corresponding to the flow is slightly larger than the calculated design lift;
2) the water flow of each chilled water pump at least meets the water flow of the water chilling unit evaporator.
