Tall and large space energy consumption optimization method based on atrium skylight material

Abstract

The invention discloses a tall and large space energy consumption optimization method based on atrium skylight materials. The method comprises the following steps: related information of the researchbuilding is collected and determined; an energy consumption analysis model and a CFD model are established according to the research building information; secondly, the temperature of each surface ofthe atrium is obtained through EnergyPlus simulation and serves as a boundary condition to be input into the CFD model; the thermal stratification characteristics of the atrium area are further obtained through CFD simulation, then the thermal stratification characteristics are input into an energy consumption analysis model to obtain high and large space energy consumption data, finally N (N is larger than or equal to 1) atrium skylight materials are set, multiple sets of energy consumption data can be obtained by repeating the process, and the optimal atrium skylight material can be obtainedthrough contrastive analysis. The method can accurately calculate the energy consumption of the tall and large space, reduce errors caused by the temperature stratification phenomenon in the atrium area, optimize the early-stage building design of the tall and large space and reduce the energy consumption of the air conditioner.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a method for optimizing energy consumption in a tall space based on the material of an atrium skylight. Background technique [0002] Large-scale public buildings generally belong to tall and large spaces. The energy consumption of such buildings is very large, especially the energy consumption of HVAC. Air conditioning energy consumption. Thermal stratification is common in tall spaces. At present, there are few studies on the impact of thermal stratification on the energy consumption of air conditioners in tall spaces. The impact of thermal stratification on energy consumption in tall continuous spaces is unknown. The solar radiation through the skylight is the main cause of thermal stratification, and reducing the solar radiation entering the room can also reduce the indoor heat and humidity load and reduce the energy consumption of air conditioning.
