The closed water loop heat pump (CWLHP) system has been shown to be an energy conserving building heating and cooling system. Such systems are most applicable where simultaneous heating and cooling needs occur. In these systems, internally generated space heat is used to meet heating needs before external heat is provided from a heating plant. The water loop is the transport system moving heat from where it is not wanted to where it is required. Addition of water storage gives an option to store thermal energy for later use. In the common arrangement for the closed water loop heat pump system, each perimeter zone is served by individual heat pumps while the cores zones are served by a central air handler. This paper reports the results of a study on the effect of component arrangement and system control strategy on the energy saving potential of the water loop heat pump used for heating and cooling of a commercial office building.
