RN&M is a leader in the design and implementation of geothermal heat pump technology. This technology has been very popular residentially for many years, however, we apply it on a large scale. Central plant equipment can be eliminated by utilizing the earth, as a heat sink. The system of vertical bores or “well field” can be located under sports fields or parking lots. The well field is a closed loop; so it is environmentally friendly (no groundwater contamination). Water is pumped from the building, out to the well field thru closed piping (where heat is either dissipated or absorbed); and the water then flows thru the water-cooled heat pump units in the building and back out to the well field. The heat pump units in the building provide heating and cooling – much like the heat pump in a typical home.
The advantages of ground source heat pump systems are:
Very efficient (35% or more less energy consumption than typical systems)
Quick payback (as low as 4 years in some cases)
Less equipment to maintain
Low sophistication level of equipment and controls (user friendly)
Long equipment life (water-cooled compressors are durable)
No outdoor equipment (no noise, no “ugly” equipment, no outdoor maintenance)
Very low net carbon footprint and emissions.
