Analysis method for comprehensive energy consumption of air conditioning system in non-heating season

Abstract

The invention provides an analysis method for comprehensive energy consumption of an air conditioning system in a non-heating season. The method comprises the following steps of a meteorological parameter setting step used for setting an indoor meteorological parameter according to a position where the air conditioning system is located; a computation model building and a boundary condition setting step used for determining a computation model and a boundary condition according to a place where the air conditioning system runs; and a comprehensive energy consumption computation step used for computing the comprehensive energy consumption of the air conditioning system by using a formula: FORMULA, according to an annual air-conditioner overall cooling load of the computation model. According to the energy consumption computation method for the air conditioning system in the non-heating season provided by the invention, computation of the energy consumption of the air conditioning system is more accurate, specific computation modes for refrigeration energy consumption, air system transmission energy consumption and water system transmission energy consumption are particularly provided, so that the different air conditioning systems can be provided for different building types of different cities and the air conditioning systems and operation modes can be improved, and thus energy consumption of the air conditioning system can be reduced.

Description

Technical field [0001] The invention relates to the technical field of computer-aided calculation, in particular to a method for analyzing comprehensive energy consumption of an air conditioning system in a non-heating season. Background technique [0002] The comprehensive energy consumption of the air-conditioning system in the non-heating season is defined as the total energy consumed in the non-heating season to eliminate indoor waste heat and humidity, including cooling energy consumption and transportation energy consumption. The refrigeration energy consumption is mainly the energy consumption of the refrigerator. Media transportation energy consumption mainly includes water system transportation energy consumption and wind system transportation energy consumption. The energy consumption of water system transportation mainly includes the energy consumption of cold water pumps (primary pumps, secondary pumps, etc.), cooling water pumps and cooling towers. The energy consum...
