(2) Geothermal heat pump system at Wetland Park, Hong Kong
(Note that geothermal heat pump is generally not considered a renewable energy technology.) The geothermal heat pump air-conditioning system (GHP A/C) has a total cooling capacity of 2500kW. It provides air conditioning for the Visitor Centre of Wetland Park. The GHP A/C system consists of a ground-coupled heat-pump air-conditioning unit, vertical geothermal closed-loop heat exchanger, and aqua-thermal closed-loop heat exchanger. The geothermal heat exchanger is formed by 468 pairs of 32mm diameter vertical high-density polyethylene pipes, each pipe being 50m in length. These pipes are inserted into boreholes and embedded in bentonite clay cement grouting for better conductivity. The aqua-thermal heat exchanger serves as a back up to the geothermal heat exchanger. It rejects heat to the water in the storage pond and the water feature of the Park.
