Ground source energy systems or geothermal heat pumps serve as an HVAC system for residential and commercial applications. It is used to heat them up in winter and cool them down in summer. With a million existing installations worldwide and several thousand installations a year throughout North America, Earth energy systems are efficient HVAC systems because of their operating principles and unique design. However, these systems have certain requirements that must be met for them to be truly efficient.
Ground source Energy systems are efficient HVAC systems based on their operating principles. First of all, earth energy systems or ground source heat pumps have heat exchangers filled with refrigerant that allows them to draw and dissipate heat. The refrigerant exchanges heat with water drawn up from a well in an open loop system or from coils of underground pipes in closed loop systems. Next, the refrigerant mixture goes through the heat pump in the house. When the refrigerant in the heat pump boils to become a vapor, the reversing valve takes the vapor to the condenser. Later on, the condenser compresses the vapor causing it to heat up. During the process, the reversing valve takes the hot gas to the condenser coil or duct system. Finally, the air passes across the coil to heat the entire property. This process can either heat up one room or all the rooms in residential or commercial properties simultaneously without the need for a mechanical room. As a result, Earth Energy systems are efficient HVAC systems based on their operating principles.
Earth energy systems are also efficient systems because of their unique design. In contrast, with regular combustion furnaces, geothermal heat pumps can be used with both hydronic heating system and forced air system. Also, these systems can be designed to install either heating only, heating with active cooling or heating with passive cooling. Although, heating systems don’t cool the...
