Commercial Geothermal Systems

Overhead Reductions for The Future


reduce operational cost of heating and cooling

Traditional HVAC systems perform air-to-air heat exchange, essentially changing the ambient temperature in the air to the desired temperature in your structure.  A commercial geothermal heat pump or ground source  heat pump (GSHP) performs a ground-to-air heat exchange.  It uses the temperature of the earth as the ambient temperature and then either heats or cools it (using traditional methods) to the desired temperature.  GSHP technology is also efficient with bodies of water.

A commercial geothermal heat pump system has high efficiencies (300%-600%) on the coldest of winter nights, compared to 175%-250% for air-source heat pumps on cool days. Ground source heat pumps (GSHPs) are among the most energy efficient technologies for providing HVAC and water heating.

This design reduces the operational cost of heating and cooling systems because moderate ground temperatures stay at a median temperature year round.  You can gain even greater efficiencies by adding solar technology to the installation.  

LOOP ENGINEERING AND DESIGN

With a traditional HVAC system your main costs are invested in the equipment used to handle the air exchange. With a GSHP systems you will invest in engineering design to clearly identify your heat loads and to quantify your soils thermal coefficient.  A clear picture of these elements will assure that you have the proper amount of heat transfer in the ground to properly condition your structure with the minimal amount of additional electricity required.  A proper engineering design will help you gain economies of scale, that facilitate the reduced cost of operation.  

LOOP FABRICATION

At ELS we custom fabricate the header for our GSHP systems.  Headers aggregate the water in the loop, which feeds the heat pump to facilitate heat exchange.  These are designed and fabricated in our shop located in Tulsa, Oklahoma.  We use specialized equipment designed to create bonded loops that will serve your installation for the life of the loop system.   

LOOP DRILLING

Today we primarily manage vertical drilling.  The drilling operation is defined clearly in the initial design to assure proper spacing and depth for optimal operation.  After drilling the loops are inserted into each well and back filled.  Back filling uses an earth based compound that is environmentally clean and actually increases your thermal coefficient.
 

 



Water stores tremendous quantities of heat. In nature, few substances have a higher specific heat (one BTU per pound) than does water, making it an ideal heat storage medium for both natural and man-made phenomena.
