The research assesses the performance of the water-to-water heat pump system installed in an water treatment plant for cooling and heating ventilation. The system uses the unused energy which is a natural heat source of 5～25℃ low temperature like river water to supply stably the demand for the cold and warm heat. For 1 year, the performance of the system had been investigated for the temperature of the raw water, used as heat source, which is varied with heat flux from the geological stratum. In summer season monthly averaged COP is ranged from 3.85 to 4.56, and the performance is dropped as the raw water temperature is increased. While, heating performance is dropped at the low raw water temperature, and the monthly averaged COP is changed from 2.92 to 3.82. There was that the temperature change of an evaporator in and out grows bigger and the cycle become unstable because of decreasing the temperature of the intake raw water. |
