A ground source heat pump system of the engineering application are reviewed

1) ground source heat pump systems: the direct use of underground Wells, its biggest advantage is very economic, cover an area of an area small, but must meet the following conditions: good water quality. Water rich; Up to the standard.

2) of the underground buried pipe: ground source heat pump system for vertical buried pipe system, it has advantages of less land occupied, less pipe and pump power, its disadvantage is that the drilling cost is higher; For horizontal buried pipe system, the advantages are: the installation costs less than vertical buried pipe system, wide application, the user easy to master, its shortcomings are: covers an area of big, affected by the ground temperature is large, the water pump power consumption.

3) surface water heat pump, its advantages are: in 10 meters or deeper in the lake, can provide direct cooling of 10 ℃, smaller than investment system of buried pipes, water pump with low energy consumption, high reliability, low maintenance requirements, low operating cost, in warm areas, the water can be used as heat source, its shortcomings are: in shallow water lake, coil easy to damage, due to temperature change is bigger, will reduce the efficiency of the unit.

4) boiler/cooling tower with a combination of buried pipes of hybrid ground source heat pump systems: apply to the space is little, can't separate the underground buried pipe heat exchange system architecture, combined refrigeration cooling tower and the closed loop system, save the cost; Facts prove that the system is high efficiency and low cost.
