Air conditioner load predicting method suitable for building planning stage

Abstract

The invention discloses an air conditioner load predicting calculation method suitable for a building planning stage. The air conditioner load predicting method suitable for the building planning stage comprises the following steps of (1) calculation of the total load of wall bodies and a roof, (2) calculation of the total load of windows, (3) calculation of the total lamplight load, (4) calculation of the total personnel load, (5) calculation of the total equipment load, (6) calculation of the fresh air load, (7) calculation of the heat load, and (8) calculation of the cold load. According tothe air conditioner load predicting method suitable for the building planning stage, based on the principle of the radiation time sequence, the building load of the planning stage is predicted, the principle of the radiation time sequence is applied to the calculation method of the air conditioner load, the necessary iterative calculation process of the model-fitting method (TFM) does not need tobe transmitted, the critical point lies in the fact that that the heat of heat transferring of an enclosure structure uses the radiation time coefficient to convert the radiation heat part into roomhourly cold and heat loads, and calculation is easy, convenient and accurate.

Description

technical field [0001] The invention belongs to the field of building heating and air-conditioning load calculation, and in particular relates to an air-conditioning load forecasting method applicable to the building planning stage. Background technique [0002] With the rapid growth of my country's national economy and the great improvement of people's living standards, the energy consumption of heating and air conditioning in buildings is increasing significantly. In addition, my country's vast territory and energy consumption problems are becoming more and more prominent. Therefore, the importance of building air conditioning load forecasting is self-evident. Metaphor. Building air-conditioning load forecasting includes building planning stage load forecasting, design stage load forecasting and operating stage load forecasting. For the prediction of cooling and heating load in the building design stage, the air conditioning system scheme can be reasonably selected, and th...

Problems solved by technology

Internationally, the heat balance method is a relatively accurate and basic load calculation method. When calculating the internal surface load, all heat transfer in the room needs to be considered, detailed input parameters are required, and the iterative calculation is cumbersome.

However, at the stage of architectural planning, only parameters such as building function, floor area ratio, building height, and land area can be provided. Obviously, the above methods are not applicable
