The construction of a plant in water-water heat pumps Requires a geological analysis by a specialist in order to know the stratigraphy of the ground that houses the ground, to estimate the masses of water available and determine the direction of water flow.
Systems in water-water heat pump can be open circuit, Exploiting in a direct way the ground water, or closed circuit, With an intermediate fluidized fluid as in the classic geothermal applications.
Open circuit applications require the presence of one or more wells for water capture and its return to the ground.
The design of such wells depends not only on the geological properties of the site, but also on the water flow required to the heat pump, considering that the required flow rate for 1 KW fluctuates between 150l / h e 200l / h.
The removal of these flow rates must be compatible with the times of groundwater recharge and must be authorized by the local authorities.
In the presence of a surface water body in communication with the flap, the return into the groundwater can take place through it instead of through a dedicated pit.
Increased reliability plants is guaranteed by indirect exchange with a heat exchanger interposed between the source and the circuit side heat pump: it thus avoids the problems related to the quality of water, obtaining the same performance as a closed circuit but with a lower investment initial.
