Calculation method of large-space layered air-conditioning load based on surface heat balance

Abstract

The invention relates to a large-space delaminated air-conditioning load calculation method based on surface thermal balance. The calculation method comprises the following steps that: S1: for a large-space building external envelope structure and a ground inner wall surface, carrying out energy analysis, establishing a heat balance equation of each inner surface of any inner wall surface; S2: according to the heat balance equation of any inner wall surface in the S1, establishing the energy equation of n pieces of inner wall surfaces of the large-space building; S3: carrying out analysis calculation on heat transferred to an air-conditioning area from a non-air-conditioning area to obtain an air heat balance expression of the non-air-conditioning area; and S4: carrying out energy analysis calculation on the air-conditioning area to obtain a large-space delaminated air-conditioning load expression. By use of the large-space delaminated air-conditioning load calculation method based on surface thermal balance, the large-space delaminated air-conditioning load calculation method with a clear concept and a specific physical meaning is provided, and the deficiency of large load errors formed by heat of transfer in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of large-space load calculation, and in particular relates to a calculation method for large-space stratified air-conditioning load. Background technique [0002] Large-space buildings refer to buildings with a height greater than 10m and a volume greater than 10,000m 3 building. Among the public buildings, sports buildings, performance buildings, exhibition buildings, transportation buildings and industrial plants are all large-space buildings. There are many types of large-space buildings with different shapes and rich connotations. With the development of society and economy, human demand for large spaces is constantly increasing. Especially in my country, large-space buildings have achieved rapid development, and their building spans have gradually increased. Buildings The structure is becoming more and more complex. Large-space buildings are regarded as a symbol of urban development and an important e...

Problems solved by technology

The value of 1.3 in the first step and the value of C2 in the second step are all empirical values, which make the calculation error

Third: The calculation of the convective transfer heat load is also obtained by manually checking the line diagram, and the line diagram is also obtained from experience, and there are errors, and there will also be errors when manually checking the map
