Optimal control of cooling tower in hybrid ground-source heat pump system for hotel buildings

strategy, energy consumption Abstract. The control strategy of the cooling tower is an important factor in the optimal operation of hybrid ground-source heat pump systems (HGSHPS). This paper selected a hotel building of cooling-dominated area as the research object. We selected multiple control operating points of two commonly used control strategies (i.e., the highest temperature control strategy and the temperature difference control strategy) for simulation. The optimal control operating points under different control strategies were then obtained on the basis of the minimum energy consumption of the HGSHPS in 20 years.
