Today I want to talk to you about last type of Geothermal Heat Pump System
that I didn't talk about in my last post (click to see). I'm talking about Pen-loop
system that uses well or surface body water as the heat exchange liquid that
courses goes through the GHP System. When it has flowed through the System, the
water comes back to the ground through the well, a recharge well, or surface release.
This alternative is clearly useful just where there is a sufficient supply of
generally clean water, and all local regulation is met with respect to
groundwater release.
I should also mention the Hybrid systems that uses different geothermal
solution, or a combination of a geothermal resource with outdoor air (i.e., a
cooling tower), are another technology option. This options is very effective
in areas where need more coolling rather than heating. Where geology permits us,
the "standing column well" is another solution. In this variation of
an open-loop system, one or more deep vertical wells is drilled. Water is drawn
from the bottom of a standing column and returned to the top.
At the times of times of peak
heating and cooling, the system can drain a segment of the return water as
opposed to reinjecting it all, bringing on water inflow to the section from the
surrounding aquifer. The drain cycle cools the section during heat rejection, heats
it amid heat extraction, and reduces the required bore depth.
