摘　　要：针对以地下水为冷源的天然能源空调系统在实际应用中,由于进风机盘管或其他换热器的冷冻水温度过高,使风机盘管或其他换热器制冷能力和除湿能力下降,以至于影响了空调的供冷效果.笔者通过对风机盘管或其他换热器的制冷能力和除湿量能力的理论计算,在理论上分析了冷冻水温度变化对风机盘管或其他换热器的制冷能力和除湿能力的影响,并提出相应的对策:增加换热面积和增加风量以及增大水流量等方法来增加风机盘管或其他换热器的制冷量和除湿量,从而达到空调供冷的使用要求.The air conditioning system of natural energy sources takes groundwater as the cold source.The chilled water temperature in the fan coil unit and other heat exchangers is very high,which makes the capacity of refrigerating and moisture removal decline,thus has influenced the operation of the air conditioning.The impact of variation in chilled water temperature on the capacity of refrigerating and moisture removal is analyzed based on the theoretical calculation of the fan coil unit and other heat exchangers.Solutions such as enlarging the area of heat interchangers,increasing the fan delivery and the flow of water are presented to increase the capacity and satisfy the demand of its operation.
