Geothermal Energy

Have you ever seen pictures of a volcano or a geyser? If so, then you’ve seen geothermal energy in action!

"Geo" means "from the earth," and "thermal" means "heat," so this type of energy is found under the earth. The hot lava from a volcano and the hot steam from a geyser both come from underground heat – and we can use that same type of heat in our homes.

Here’s how it works: about four feet underground, the temperature of the earth stays the same all year long - about 55 degrees.

Environmentally Engineered Equipment's Geothermal heat pump is a self-contained water-cooled packaged heating and cooling units with a reversible refrigerant cycle. Depending on the model, components are typically enclosed in a common casing, and include plate to plate heat exchangers, a heating/cooling coil, a compressor, a fan, a reversing valve and controls.  gas.

Application Considerations

The Geothermal heat pump is, by definition, a full heating system. It may be applied to buildings that have simultaneous cooling and heating loads. This is the case during winter months during which some units cool interior zones while others heat perimeter zones. The heat rejected by cooling units is used to warm the zones calling for heat.

Often, multiple units serve an occupied space, so, if one were to fail, the other units could back it up until the unit is repaired. The packaged design of most unit types allows quick change-out by service personnel so maintenance can be performed off site.

Advantages

Geothermal Heat Pumps save money and lower energy consumption by utilizing geothermal sources of heat, not dependant on outside or ambient temperature. Therefore, no external heat "make-up" heat is required, not matter of local conditions.

Heat pump units are installed inside the building; they aren't exposed to the weather. This is especially important, for example, in coastal areas were the atmosphere can be very corrosive.

These are very flexible. The system can be subdivided or expanded into new zones to fit building remodeling or additions easily and inexpensively.
