Experimental Study and System Optimization on Ground Source Heat Pump System in the Heating Mode

The paper measures a ground source heat pump system which is running in the heating mode in a hotel in Hunan. And analyze how the circulation loop water flow influences the coefficient of performance of the heat pump units and the whole system. According to operating states of the ground source heat pump system, frequency conversion technology is purposed to be applied in the deep well pump so as to save much energy. The feasibility of the project is demonstrated in detail based on equivalent peak hour theory from energy saving property and static recycling period.
