Description

This paper searches for the reason for the difference between the air-conditioning load calculation by HASP/ACLD/8001 and air-conditioning energy consumption. The causes of the difference between AHET and cooling energy consumption are cooling period, whether there is package unit or fancoil unit, density of the inside illumination and draft load. The difference can be explained by these factors. And AHET is greater than the actual energy consumption. The difference between AHST and heating energy consumption is caused by the heating period, whether or not air-conditioning uses an air source or water source area of windows, total floor space and the existence of peaple. But it cannot be explained by these factors as in the case of cooling.
