River and lake water source heat pump central air-conditioner

In the area, where the  river and lake water temperature is  over 7centi degree throughout the year, normal flooded or dry type unit can be applied. And in the area where the water temperature is between 7centi degreeand 3 centi degree all the year, the unit can be specially designed according to the water flow rate. and the heat exchanging method can be designed flexibly basing on the geology and environment to achieve the highest COP and EER.

In 2004, Fuerda ground source heat pump unit was successfully applied in a five-star hotel of Guizhou Province and achieved a complete success, creating a precedent for promoting and utilizing surface water and ground heat pump in the south of China. In the south of the Changjiang River, the water temperature of the rivers and lakes is higher than 7 in average, so these areas are suitable for extensive promotion and application of this series of water source heat pump.
