摘要
为开展果蔬大棚的对比测试,在试验大棚设置了空气源热泵-风机盘管系统,对比大棚保持原样,测试两个大棚内空气温度、土壤温度以及热泵机组性能参数。结果表明:未设置空气源热泵机组时,对比大棚内空气平均温度很低,平均温度只有13.5℃,远低于试验大棚的23.8℃,二者最低气温相差14℃左右;试验大棚的土壤温度也比对比大棚高4℃左右;试验大棚空气源热泵的平均COP在3左右,性能良好。
In order to carry out the contrast test of fruit and vegetable greenhouses, air source heat pump, fan coil system was arranged for an experimental greenhouse, and contrast greenhouse intact. The air temperature, soil temperature and heat pump unit performance parameters were tested. The results showed that when the air source heat pump unit was not set, the average temperature in the greenhouse was very low; the average temperature was only 13.5 ℃, far below the 23.8 ℃ in the experimental greenhouse. The soil temperature of the experimental greenhouse was higher than that of the greenhouse by about 4. The experimental greenhouse heat pump has good performance, the average COP was about 3.
