Energy-saving analysis meteorological year calculation method, system and device and storage medium

Abstract

The invention discloses an energy-saving analysis meteorological annual calculation method, system and device and a storage medium. The method is used for hourly dynamic building energy consumption simulation. According to the energy-saving analysis meteorological year AEEMY, the dry-bulb temperature, the horizontal plane solar total radiation, the atmospheric pressure and the relative humidity are used as main meteorological parameters for judging and representing the climate year, a principal component analysis method is used for determining the combination weight of the four main meteorological parameters, the energy-saving meteorological month is selected according to the combination value of the four parameters, and therefore the typical meteorological year is formed through combination. According to the method, fewer meteorological parameters than TMY2 are used, so that the selection of the AEEMY is simpler, and the AEEMY fully considers the difference of climate factors of different regions and different seasons on the building energy consumption effect, so that more locally represented energy-saving analysis meteorological data can be selected, and the influence of the climate on the building energy consumption can be reflected more accurately.

Description

technical field [0001] The invention belongs to the field of building energy consumption, in particular to an energy-saving analysis meteorological year calculation method, system, device and storage medium. Background technique [0002] Energy consumption in buildings for heating, ventilation and air conditioning accounts for a large share of the overall global energy balance. In 2017, the International Energy Agency (IEA) proposed that the energy consumed by buildings during construction and operation accounted for 36% of global energy use, and energy-related carbon dioxide emissions accounted for 39% of global carbon dioxide emissions. More important and urgent. Climate is a key factor in determining building energy consumption. The modern dynamic simulation method of building energy consumption is based on this to accurately calculate the hourly energy consumption of a specific building under local climate conditions throughout the year. The dynamic simulation method o...

Problems solved by technology

In the existing technology, the actual meteorological year is usually selected from the historical observation data center as the simulated meteorological data, and the data is not perfect and accurate, which affects the calculation of the simulation software.
