Abstract

The invention discloses a method for calculating the refrigeration air conditioning degree days of a public building and relates to the technical field of energy conservation. The method achieves the technical effect of reducing the errors of air conditioning energy consumption evaluation. The method comprises the steps that a 24-hour air conditioning operating vector of the public building is set according to the running time periods of the public building; a 24-hour air conditioning refrigeration vector of the public building is calculated in combination with the calculated temperature limit value of the air conditioning degree days, the pre-booting time of an air conditioning load, the advanced stop time of the air conditioning load and the average temperature value of all the time periods; the refrigeration air conditioning degree days of the public building in the calculation day are further calculated according to a calculated result of the 24-hour air conditioning refrigeration vector of the public building. The method is suitable for air conditioning energy consumption evaluation of the public building.

Description

technical field [0001] The invention relates to energy-saving technology, in particular to a technology for calculating the degree-days of refrigeration and air conditioning in public buildings. Background technique [0002] In the energy-saving design standards, the annual power consumption of refrigeration and air-conditioning in the comprehensive index of building energy-saving is determined according to the number of air-conditioning degree days in the location of the building. Multiply the number of degrees higher than the specified temperature by 1 day, and then accumulate the multiplication in a year to obtain the degree-day index reflecting the power consumption of the air conditioner. [0003] In the existing calculation method of refrigeration and air-conditioning degree days of public buildings, the average temperature is the average value of temperature values ​​at several time points in a day, and these time points are evenly distributed at certain time interval...
