Abstract
In this paper, the design procedure of hybrid heat source heat pump system coupling of ground-source and air-source is discussed at the early design phase of air-conditioning system for a commercial building. A design procedure for determining capacity balance of ground-source and air-source is presented, then the design parameters should be considered in the design procedure are described. Based on the proposed design procedure, the case study is conducted. The results of case study show that the capacity balance of heat pump coupling ground-source and air-source is influenced by the amount of peak load of a building and a building coverage ratio. Also, the maximum capacity balance would be considered in the case of conceivable condition is provided, it could be a criterion while a system designer define a capacity balance of hybrid heat source heat pump system.
