Abstract

The invention provides a selection method for host equipment applied to an air-conditioning system. The method comprises the steps that an annual air-conditioning load is calculated, a calculation model is determined according to the characteristics and geographic position of a building, relevant parameters of the calculation model are acquired according to boundary conditions, and an annual air-conditioning cooling load is calculated in the calculation model; the running duration of the refrigeration host equipment under a partial load is determined, wherein the running duration of the refrigeration host equipment under the partial load is analyzed and determined according to the annual air-conditioning cooling load obtained through the calculation model; the refrigeration host equipment is selected, and a refrigeration host equipment running scheme with the highest energy-saving rate is selected and determined; and the energy-saving rate of the selected and determined refrigeration host equipment running scheme is verified. The method is a new method for refrigeration host equipment model selection in air-conditioning system design, it is convenient to select different kinds of air-conditioning refrigeration host equipment for different building types of different cities and improve the air-conditioning system and the running mode, therefore, energy is saved, consumption is reduced, and the air-conditioning system is more reasonable in design.

Description

technical field [0001] The invention relates to the technical field of computer-aided calculations, in particular to a method for selecting refrigeration host equipment used in an air-conditioning system. Background technique [0002] The selection of refrigeration host equipment is the most important part of air conditioning system design. At present, the commonly used method for selecting the type of refrigeration host equipment is to first determine the minimum capacity of one refrigeration host according to the functional characteristics of the building, usage conditions, and the hourly cooling load variation law of the air conditioner on the design day, and then determine the maximum hourly cooling load of the air conditioning system Subtract the determined cooling host capacity, and determine the type, number and capacity of the remaining cooling hosts according to the principle of economical best. For the convenience of procurement and operation, the capacity of the r...
