Review on the application of several ground source heat pump systems

 

Ground source heat pump system of underground pipe for vertical buried pipe system, the utility model has the advantages of small occupation of land, pipeline and pump less electricity, its disadvantage is high cost for drilling; horizontal buried pipe system, the utility model has the advantages of low installation cost than vertical buried pipe system, widely used, users easy to master, its disadvantages are: large area, ground temperature, water pump power consumption. 

 

The surface water heat pump, its advantages are: in the 10 meters or deeper lake, can provide 10 degrees of direct cooling, than the underground buried pipe system to pump investment small, low energy consumption, high reliability, low operation cost, low maintenance requirements, in warm regions, water as heat source, its disadvantages are: in shallow water the coil can be destroyed, because the water temperature changes greatly, reduces the efficiency of the unit. 

 

Hybrid ground source heat pump system of boiler / cooling tower and underground pipe combination: suitable for small space, not solely by the underground pipe heat exchanger system building, cooling tower and a closed loop system combined cooling, saving the cost; it is proved that this system is of high efficiency and low cost.
