There are four differing kinds of geothermal heat pumps available today.
Each has a distinct way of connecting to the heating distribution technique in your house or creating. Some types tend to be more efficient than others at offering space conditioning on the setting up, but that is a assets in the distribution.
Every one of these GSHP forms nevertheless get their Strength from the ground loop, which transfers the absorbed warmth into The interior refrigerant loop. It really is what comes about to the warmth following that is exactly what can make the distinction between kinds.
The four different types of geothermal warmth pumps are water to air, water to h2o, combo and break up warmth pumps.
Water to Air
The 1st and doubtless most made use of geothermal heat pump may be the drinking water to air warmth pump. This heat pump is employed for houses with pressured air techniques, and essentially replaces a traditional furnace. The bottom loop provides in absorbed heat for the refrigerant loop (the water percentage of "drinking water to air"). That refrigerant is then compressed and cycled before a lover coil unit to generally be despatched via duct work distribution to your home (the air part of "drinking water to air". This process can even be switched in reverse to deliver cooling to your composition.
A single doable style difficulty may be the sizing on the ductwork. Due to the fact geothermal programs are viewed as a low temp warmth resource, a greater quantity of air is needed to deliver exactly the same heating or cooling load. This tends to both call for larger sized ductwork to accommodate for that bigger air quantity, or possibly a specialized, smaller-duct, large-velocity forced air program like Unico or SpacePak.
Water to Drinking water
The next kind is usually a drinking water to h2o, or hydronic. This type capabilities the same as all other heat pumps on the ground loop aspect from the refrigerant, but as an alternative to sending the compressed and heated refrigerant to the lover coil, it really is transferred straight into One more water loop that circulates from the heat pump, and in to the water-based distribution. This hydronic distribution is mostly radiant warmth (Radiant and Geothermal Short article), but it surely can also be utilized at the side of a domestic scorching h2o or perhaps a exterior snow melt technique.
Combo
The third form is really a combo unit. This combines the prior two heat pumps, supplying each forced air and hydronic distribution. This is ideal in homes or buildings in which the two forms of distribution are required. Some zones may very well be quite significant heat loss, which include rooms with major windows, or close to an exit door that is constantly open up, and would require a lot more heat during the Room than just radiant or maybe forced air could deliver. This is when a combo device offering both could come in quite useful.
The last type of pump available on the market is known as a split warmth pump. This kind is largely the same as an everyday warmth pump to the h2o facet, nevertheless it sends the refrigerant in a protracted loop to your remote air handler. This causes it to be simpler in much larger Positions to maintain the geothermal device while in the mechanical room with all of the loop discipline connections, and continue to have an air handler offering warmth to warmtepomp deurne a hard to succeed in spot, such as the 2nd Tale of a giant house. This allows for better adaptability in the overall design from the heating distribution process.
