Ventilation humidity control in residences in hot summer and cold winter region. Part 1: Standard summer meteorological parameters and ventilation cooling loads.

This paper founds the procedures of standard summer meteorological parameters in hot summer and cold winter region, determines the hourly meteorological model of dry and wet temperature change for sunny days, cloudy and rainy days, and builds up Chongqing's standard summer meteorological parameter database. Then based on hourly-degree method, this paper also analyses the ventilation cooling loads with new concepts such as ventilation cooling load index (VCLI), ventilation cooling temperature degree hour (CDH), cooling wetness hour (CWH0 and cooling enthalpy hour (CEH_. The quantity and distribution of ventilation sensible latent and total heat cooling loads statistically sum, which suggests the quantity of latent and sensible loads is so different in dimension and the distribution is seldom concurrent.
