空调设计中,常用一个有代表性的气象状态点作为设计参数。温焓法是用温度、焓及其修正值来确定室外状态点,进行空调的冷负荷计算。一、室外状态点的确定根据《暖通规范》,室外状态点按下列方法确定: 1.夏季空调室外计算干球温度,采用历年平均每年不保证50小时干球温度。 2.夏季空调室外计算焓值,按室内温湿度不保证时间平均每年不超过50小时确定,即室外计算焓值I_(Wj)等于统计焓值I_(Wt)减去焓修正值△Iw。
In air conditioning design, a representative meteorological state point is often used as a design parameter. The Wenyu method uses the temperature, enthalpy and its correction values to determine the outdoor status point and calculates the cooling load of the air conditioner. I. Determination of outdoor status points According to the “HVAC Standard”, the outdoor status is determined according to the following methods: 1. Summer air-conditioning calculates the dry-bulb temperature outside the air-conditioner. The annual average annual dry bulb temperature of 50 hours is not guaranteed. 2. Summer air conditioning outdoor calculation of the value of ,, according to indoor temperature and humidity does not guarantee the average time is not more than 50 hours a year, that is, outdoor calculation 焓 I_ (Wj) is equal to statistical 焓 I_ (Wt) minus 焓 correction △ Iw.
