Abstract

The invention discloses a cooling and heating load calculation method for a large-scale regional cooling and heating energy station. The method comprises the following steps: (1) collecting data and obtaining meteorological parameter data of an area where a project is located: collecting energy consumption building area and building type information of each block of a cooling and heating area; determining air conditioner calculation outdoor temperature parameters of the area according to the meteorological parameter data; (2) determining the typical building types of the cooling and heating areas, namely classifying the building types according to the conditions of the energy-consuming buildings, such as residential buildings, commercial buildings, commercial buildings, school buildings and hospital buildings, as the typical building types for load calculation. The method overcomes the defects of large installation scale and high investment caused by large design load of an energy station in the prior art, and has the advantages that the cold and heat load indexes of different types of buildings can be obtained through calculation, and meanwhile, the occurrence time of the daily cold and heat load peak value can be obtained.

Description

technical field [0001] The invention relates to the technical field of regional cooling and heating planning, and more specifically relates to a cooling and heating load calculation method for large-scale regional cooling and heating energy stations. Background technique [0002] With the improvement of people's living standards, the call for central heating in the Yangtze River Basin in my country has been increasing in recent years. In order to meet the needs of buildings for cooling in summer and heating in winter, district cooling and heating projects suitable for southern regions have gradually increased. Among them, large-scale The energy supply area of ​​the cooling and heating project exceeds one million square meters, and there are various types of energy-consuming buildings, including residential, commercial, business, schools, hospitals, etc. [0003] Due to the long development and construction cycle of large-scale district cooling and heating areas, the construct...
