Heat pump with ice production from river water -Project Seilduksfabrikken A/S.

Author(s) : ROSVIK S., ALBRIGTSEN R., FLAGSTAD O. A.

Summary

The heat pump has several features that make it interesting as a prototype: the working medium is ammonia; the system produces ice when the river water is too cold (2 deg C) to give enough heat by simply cooling the water. The latent heat is then utilized by freezing some of the water. When the buildings have both a cooling and a heating demand, the heat pump supplies both cooling and heating. In the project the convector fluid is water, and the water temperature is regulated as a function of the ambient temperature. The highest water temperature is 45 deg C, which occurs on the coldest winter day (-20 deg C). The article is based on results of the first year in operation.
