GEOTHERMAL HEATING AND COOLING

heat pumps (and central air conditioners) need a large outside unit to exchange heat with the outdoor air. Geothermal Heating and Cooling Systems In a geothermal heating and cooling system, the heat pump is connected to the building by a distribution system -- most commonly air ducts. And the heat pump is connected to the earth through a series of

Room Air Distribution When variable-flow cooling and constant-flow heating are combined in a zone, the zone air diffusers are usually selected at partial cooling load to ensure proper operation. Ceiling-mounted linear slot diffusers are recommended since they perform well over a wide range of velocities. Cool air delivery takes advantage of the

Standard Direct Expansion (DX) Cooling Air Conditioning …

Benefit: Hot gas reheat controls the supply air temperature and relative humidity without the need for auxiliary post heat (i.e. an electric heater). Hot gas reheat is often referred as “free reheat” as the refrigeration system needs to reject the heat absorbed by the refrigerant to the ambient air or supply air for proper operation.

Thermal Comfort (Relative Humidity (RH) and Air …

humidity, the air moisture condenses – this is called the dew point. Air temperature is a measure of the heat. Most thermometers are measuring ambient air heat. However, radiant heat loss or gain is also important. Radiant heat may not be reflected in the air temperature, but is the impact of cold or hot objects in the area.
