You will discover four different types of geothermal heat pumps currently available.
Each one has another way of connecting into the heating distribution program in your house or making. Some kinds are more economical than Other people at delivering Area conditioning into the building, but that is a house on the distribution.
All of these GSHP kinds nonetheless get their Strength from the ground loop, which transfers the absorbed warmth into The inner refrigerant loop. It can be what occurs to the heat after that is what can make the difference between styles.
The four different types of geothermal heat pumps are h2o to air, drinking water to water, combo and split heat pumps.
H2o to Air
The first and possibly most employed geothermal heat pump may be the h2o to air heat pump. This warmth pump is employed for houses with forced air methods, and mainly replaces a traditional furnace. The ground loop brings in absorbed warmth towards the refrigerant loop (the water part of "h2o to air"). That refrigerant is then compressed and cycled before a enthusiast coil unit to get sent by duct function distribution to the home (the air part of "water to air". This method can even be switched in reverse to provide cooling to the structure.
One particular feasible design and style issue is definitely the sizing from the ductwork. For the reason that geothermal programs are thought of a small temp heat source, a higher quantity of air is required to deliver exactly the same heating or cooling load. This will likely possibly have to have greater ductwork to support for your higher air volume, or maybe a specialised, modest-duct, significant-velocity pressured air procedure like Unico or SpacePak.
Drinking water to H2o
The second sort is really a water to drinking water, or hydronic. This type capabilities the same as all other warmth pumps on the bottom loop side on the refrigerant, but as opposed to sending the compressed and heated refrigerant into a admirer coil, it is actually transferred directly into A different h2o loop that circulates in the heat pump, and in to the water-centered distribution. This hydronic distribution is most often radiant heat (Radiant and Geothermal Article), nonetheless it will also be employed along with a domestic scorching h2o or a outside the house snow melt procedure.
Combo
The third type is a combo unit. This brings together the preceding two heat pumps, delivering both of those compelled air and hydronic distribution. This is ideal in houses or properties in which both equally sorts of distribution are required. Some zones may very well be incredibly significant heat reduction, for instance rooms with big Home windows, or in close proximity to an exit door that is consistently open up, and would require a lot more heat while in the Room than simply radiant or just compelled air could deliver. This is where a combo unit providing both of those could can be found in incredibly useful.
The final form of pump available on the market is referred to as a break up warmth pump. This sort is basically the same as a regular heat pump over the h2o facet, but it sends the refrigerant in a lengthy loop to some remote air handler. This can make it much easier in much larger Work to maintain the geothermal unit while in the mechanical place with every one of the loop area connections, and continue to have an air handler offering warmth to a hard to reach spot, such as the 2nd story of a large house. This permits warmtepomp deurne for bigger versatility in the general style and design on the heating distribution system.
