Desiccant Dehumidification Energy Recovery
Condensation Recovery Evaporative Cooling
Geothermal & Water Source Heat Pumps
Cooling is the transfer of energy by virtue of a difference in temperature between the cooling source and the space or air. In the usual cooling process, air is circulated over a surface maintained at a low temperature. The surface may be in the space to be cooled or at some remote location from it, the air being ducted to and from the space. Usually water or a volatile refrigerant is the cooling medium.
Cooling systems are often oversized; equipment like lights and computers put off less heat now that in the past. Simulating the whole building's energy use during design can help properly size the cooling equipment.
Growing use of cooling is contributing to high demand for power in the summertime months. To meet this demand, more power plants are being built. Minimizing cooling loads not only reduces your bills, it also reduces the need for more power plants.
Overall HVAC system efficiency should be considered when altering chiller settings. The complex interrelationships of chiller system components can make it difficult for operators to understand the effects of their actions on all components of the systems. For example, one way to improve chiller efficiency is to decrease the condensing water temperature. However, this requires additional cooling tower operation that may actually increase total operating costs if taken to an extreme. In humid climates, increasing the chilled water temperature to save energy may unacceptably reduce the effective removal of humidity if the coil size is not also adjusted.
