There are actually four different types of geothermal heat pumps available today.
Each one has a special technique of connecting to your heating distribution system in your house or constructing. Some types are more effective than others at providing House conditioning for the creating, but that is a house with the distribution.
All of these GSHP types even now get their energy from the ground loop, which transfers the absorbed heat into The inner refrigerant loop. It's what comes about to the heat following that is exactly what tends to make the distinction between varieties.
The four differing kinds of geothermal heat pumps are h2o to air, h2o to water, combo and break up warmth pumps.
H2o to Air
The initial and doubtless most utilized geothermal warmth pump may be the water to air heat pump. This heat pump is used for homes with pressured air techniques, and essentially replaces a conventional furnace. The ground loop brings in absorbed heat to your refrigerant loop (the h2o part of "drinking water to air"). That refrigerant is then compressed and cycled before a supporter coil device being despatched by duct do the job distribution to the house (the air portion of "drinking water to air". This method may also be switched in reverse to offer cooling to your composition.
1 feasible structure challenge is definitely the sizing of your ductwork. Due to the fact geothermal methods are thought of a very low temp heat supply, an increased quantity of air is required to deliver the identical heating or cooling load. This can both need larger ductwork to support for that larger air quantity, or simply a specialized, tiny-duct, substantial-velocity compelled air process like Unico or SpacePak.
Water to Water
The 2nd form can be a drinking water to h2o, or hydronic. This sort features similar to all other warmth pumps on the bottom loop side with the refrigerant, but in place of sending the compressed and heated refrigerant to the fan coil, it is actually transferred directly into A different h2o loop warmtepomp deurne that circulates in the heat pump, and into your water-dependent distribution. This hydronic distribution is mostly radiant heat (Radiant and Geothermal Write-up), nevertheless it can even be made use of together with a domestic warm water or maybe a outside snow melt program.
Combo
The third form is often a combo unit. This combines the prior two heat pumps, supplying the two forced air and hydronic distribution. This is ideal in homes or structures where both equally kinds of distribution are required. Some zones might be quite substantial warmth reduction, for instance rooms with big Home windows, or in the vicinity of an exit doorway that is continually open, and would require extra warmth within the Room than just radiant or just pressured air could offer. This is where a combo device delivering equally could are available in quite useful.
The final kind of pump in the marketplace is known as a split warmth pump. This kind is essentially similar to a regular heat pump over the water aspect, nonetheless it sends the refrigerant in a long loop to a distant air handler. This can make it much easier in much larger Work opportunities to help keep the geothermal device while in the mechanical space with all of the loop area connections, and however have an air handler providing heat to a hard to achieve place, including the second Tale of a large home. This permits for greater versatility in the general style from the heating distribution process.
