Embodiment

[0041] The energy flow chain diagram of the centralized air conditioning system using the water-cooled chiller as the cold source in the present invention is as follows figure 1 As shown, in the embodiment of the present invention, the centralized air-conditioning system with the water-cooled chiller as the cold source is taken as the research object for analysis. In the cooling mode, the operation of the air conditioning system can be regarded as an energy flow chain diagram composed of 5 continuous loops from heat removal in the air-conditioned room to heat discharge to the environment. The 5 continuous loops are the indoor air loop, refrigeration water loop, refrigerant loop, cooling water loop and outdoor heat removal loop, wherein,

[0042] Indoor air loop: the cold air processed by the cooling coil is driven by the fan into the air-conditioning area to eliminate the residual heat and humidity in the area. This loop transfers the heat in the air-conditioning area to the c...

Abstract

The invention relates to an analysis method for operation energy consumption of a central air-conditioning system taking a water-cooled chiller as a cold source. The analysis method completely includes all loops and all links of the operation energy consumption of the whole air-conditioning system, and various influence factors are classified into two classes, namely consumption power ei of unit fluid flow flowing through each main energy consumption and power device and fluid volume delivered by the equipment. The analysis of the operation energy consumption of the whole air-conditioning system is comprehensive, and essence of problems is grasped.

Description

technical field [0001] The invention is an analysis method of energy consumption for the operation of a centralized air-conditioning system with a water-cooled chiller as a cold source, and belongs to the innovative technology of the analysis method for the energy consumption of a centralized air-conditioning system with a water-cooled chiller as a cold source. Background technique [0002] In my country's energy consumption structure, building energy consumption accounts for about 30% of the total energy consumption of the whole society. Among building energy consumption, air conditioning system energy consumption is the largest component. According to statistics, the energy consumption of centralized air-conditioning systems in public buildings accounts for 40% to 60% of the total energy consumption of buildings. [1] . It can be seen that reducing the energy consumption of the central air-conditioning system (HVAC) is an important way to achieve building energy conservati...
