You will find four different types of geothermal heat pumps available today.
Each has a distinct method of connecting on the heating distribution system in your house or building. Some styles tend to be more economical than Many others at offering space conditioning to the creating, but That could be a home on the distribution.
These GSHP varieties even now get their Electricity from the bottom loop, which transfers the absorbed heat into the internal refrigerant loop. It can be what occurs to the warmth following that is exactly what helps make the distinction between kinds.
The four different types of geothermal warmth pumps are water to air, h2o to drinking water, combo and break up heat pumps.
Water to Air
The 1st and doubtless most employed geothermal heat pump is the h2o to air warmth pump. This warmth pump is used for houses with pressured air devices, and mainly replaces a traditional furnace. The bottom loop brings in absorbed heat into the refrigerant loop (the drinking water percentage of "water to air"). That refrigerant is then compressed and cycled in front of a enthusiast coil device to be despatched as a result of duct function distribution to your house (the air percentage of "drinking water to air". This method will also be switched in reverse to offer cooling to your framework.
One particular attainable style and design difficulty may be the sizing on the ductwork. For the reason that geothermal units are thought of a small temp warmth supply, a higher quantity of air is required to deliver precisely the same heating or cooling load. This could either have to have much larger ductwork warmtepomp deurne to accommodate for that higher air quantity, or possibly a specialized, smaller-duct, higher-velocity forced air program like Unico or SpacePak.
H2o to Water
The next style is really a water to h2o, or hydronic. This sort features similar to all other warmth pumps on the bottom loop facet of your refrigerant, but instead of sending the compressed and heated refrigerant to a admirer coil, it's transferred straight into A further h2o loop that circulates through the heat pump, and to the water-centered distribution. This hydronic distribution is mostly radiant heat (Radiant and Geothermal Posting), but it will also be employed along side a domestic incredibly hot drinking water or simply a outdoors snow soften system.
Combo
The third kind is a combo unit. This brings together the earlier two heat pumps, furnishing both forced air and hydronic distribution. This is perfect in homes or structures exactly where both equally different types of distribution are needed. Some zones could possibly be extremely substantial warmth reduction, such as rooms with significant windows, or in close proximity to an exit door that is continually open, and would require additional heat during the Place than just radiant or simply pressured air could supply. This is where a combo device delivering the two could come in pretty useful.
The final form of pump out there is recognized as a break up heat pump. This sort is essentially the same as a regular heat pump over the drinking water aspect, but it surely sends the refrigerant in a protracted loop into a remote air handler. This can make it simpler in greater Employment to maintain the geothermal unit while in the mechanical area with every one of the loop area connections, and however have an air handler delivering warmth to a hard to achieve put, like the next Tale of a giant house. This enables for higher versatility in the general design and style from the heating distribution program.
