Embodiment Construction

[0033] In an embodiment of the present invention, a central air-conditioning equipment selection method and system are provided. The method includes: automatically finding a plurality of eligible air-conditioning unit equipment combinations in the air-conditioning equipment database according to the performance index requirements of the central air-conditioning, Then perform system energy consumption simulation on the multiple air-conditioning unit equipment combinations respectively, and arrange the multiple air-conditioning unit equipment combinations according to energy efficiency. The performance index requirements of the central air conditioner include: cooling load of the air conditioner, inlet and outlet temperature of chilled water, and inlet and outlet temperature of cooling water. The air conditioner equipment combination includes a chiller combination, a chilled water pump combination, a cooling water pump combination and a cooling tower.

[0034] It should be noted...

Abstract

The invention discloses a device selection method and system of a central air conditioner. The device selection method comprises the steps that a plurality of air conditioner unit device combinationsconforming to conditions are automatically found out in an air conditioner device database according to performance index requirements of the central air conditioner, then the multiple air conditionerunit device combinations are subjected to system energy-consumption simulation, and the multiple air conditioner unit device combinations are arrayed according to the energy efficiency. By adopting the technical scheme, accurate selection of various devices of a central air conditioning system can be achieved quickly.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a method and system for selecting a central air conditioner. Background technique [0002] The energy efficiency of conventional central air-conditioning systems on the market today is not as high as expected in the initial design stage. Even if the control and operation strategy of the air-conditioning system is adjusted, there is no improvement. The selection of system equipment plays a vital role in the energy-saving operation and maintenance of the air conditioning system in the future. [0003] At present, the energy efficiency of conventional central air-conditioning systems on the market is not as high as expected at the initial stage of design. In the second case, the power of the central air conditioner is less than the actual demand of the user, resulting in insufficient cooling. Contents of the invention [0004] The object of the present invention is to propose a c...
