You'll find 4 different types of geothermal heat pumps available today.
Each one has a unique method of connecting to the heating distribution procedure in your house or developing. Some sorts are more productive than Many others at providing space conditioning on the building, but That may be a home from the distribution.
These GSHP varieties continue to get their energy from the bottom loop, which transfers the absorbed heat into The interior refrigerant loop. It is really what happens to the heat after that is what tends to make the distinction between varieties.
The four different types of geothermal warmth pumps are drinking water to air, water to drinking water, combo and break up heat pumps.
Water to Air
The initial and possibly most made use of geothermal heat pump may be the water to air warmth pump. This warmth pump is useful for properties with forced air programs, and in essence replaces a traditional furnace. The ground loop provides in absorbed warmth towards the refrigerant loop (the h2o percentage of "h2o to air"). That refrigerant is then compressed and cycled before a fan coil unit to generally be despatched as a result of duct operate distribution to your house (the air part of "drinking water to air". This process may also be switched in reverse to provide cooling to some structure.
1 doable design and style situation could be the sizing from the ductwork. For the reason that geothermal methods are regarded as a very low temp warmth supply, a better volume of air is necessary to deliver the identical heating or cooling load. This will likely possibly demand bigger ductwork to support with the bigger air volume, or even a specialized, compact-duct, large-velocity pressured air program like Unico or SpacePak.
H2o to H2o
The second style is often a h2o to water, or hydronic. This sort functions the same as all other warmth pumps on the bottom loop facet of your refrigerant, but rather than sending the compressed and heated refrigerant to your admirer coil, it is actually transferred immediately into Yet another drinking water loop that circulates from the heat pump, and into the h2o-based distribution. This hydronic distribution is most often radiant warmth (Radiant and Geothermal Post), nonetheless it will also be utilized along side a domestic warm water or maybe a outside the house snow melt technique.
Combo
The third form is often a combo device. This brings together the prior two warmth pumps, supplying both of those forced air and hydronic distribution. This is perfect in homes or properties where by the two forms of distribution are needed. Some zones may be very significant heat loss, warmtepomp deurne for instance rooms with large Home windows, or close to an exit doorway that is consistently open up, and will require far more heat during the space than just radiant or maybe compelled air could supply. This is when a combo unit providing equally could come in quite useful.
The last sort of pump available on the market is named a split warmth pump. This type is essentially similar to a daily heat pump within the h2o side, but it surely sends the refrigerant in a long loop to a distant air handler. This makes it easier in much larger Work to maintain the geothermal device while in the mechanical place with the many loop discipline connections, and even now have an air handler offering heat to a tough to succeed in put, such as the next story of a large residence. This allows for bigger versatility in the overall style and design in the heating distribution process.
