Research on the Control of Heat Balance System of Ground Source Heat Pump with Cooling Tower Compensation
Using cooling tower to reduce soil heat in summer is one of the most common heat balance measures for ground source heat pumps,but the corresponding control strategy is not perfect.In this paper,for the heat balance system of ground source heat pump with cooling tower compensation,a dual-mode operation control strategy with efficiency priority and heat compensation is proposed.This control strategy defines the conditions of bidirectional switching between the cooling tower and the buried pipe,which can improve the working efficiency of the ground source heat pump system on the premise of maintaining the underground heat balance of the buried pipe,and can automatically adapt to buildings with different load characteristics.
