摘要
对原系统中存在的夏季排气压力超标、噪声高，冬季吸气压力偏低等问题进行分析，采取相应改造措施。工程改造结果表明：在石家庄地区的中小规模建筑中，夏季选用风冷式冷水机组配以蒸发冷却方式与单独风冷式冷水机组供冷相比，制冷量提高９ ％ ；冬季利用蒸汽配以即热式汽水换热器供热与热泵供热方式相比，运行费用降低２０ ％ 。这种空调系统特别适合夏季相对湿度较低。
Analyses the troubles such as too high discharge pressure and noise level in summer, and too low suction pressure in winter in the original air conditioning system, adopts corresponding reconstruction measures. Considers that for small and middle scale buildings in Shijiazhuang area, when using air cooled units plus an evaporative cooling system instead of the air cooled unit alone in summer, the refrigerating capacity can be increased by 9%; and when using the instant steam water heaters for heating in winter rather than only using the heat pump unit, the operating cost can be reduced by 20%. This kind of air conditioning system is suitable for districts with lower relative humidity in summer and central heating in winter.
