Optimal Control Strategies for Ice Storage System of Water Source Heat Pump

Abstract:

In order to overcome the limitations of single application of ice storage cold and water source heat pump technology, the organic combination of the two can “peak load shifting” and save the cost of system operating. It is important to know how to reasonably distribute the load, which makes the system run with minimum cost. By comparing the operating costs of several control strategies for ice storage system of water source heat pump in a CBD, the advantages of control strategies for dynamic load distribution is outstanding by comparing with the priority control strategies of chiller or ice storage.
