The first of the cooling load factors used in this method is the CLTD, or the Cooling Load Temperature Difference. This factor is used to represent the temperature difference between indoor and outdoor air with the inclusion of the heating effects of solar radiation. [1] [5] The second factor is the CLF, or the cooling load factor.
A chilled beam is a type of radiation/convection HVAC system designed to heat and cool large buildings through the use of water. [1] This method removes most of the zone sensible local heat gains and allows the flow rate of pre-conditioned air from the air handling unit to be reduced, lowering by 60% to 80% the ducted design airflow rate and the equipment capacity requirements.
Cooling towers are structures for cooling water or other heat transfer media to near-ambient wet-bulb temperature. Wet cooling towers operate on the evaporative cooling principle, but are optimized to cool the water rather than the air. Cooling towers can often be found on large buildings or on industrial sites.
The district cooling plant is operated by SP Group's subsidiary, Singapore District Cooling. [17] A second district cooling plant was commissioned in May 2010, [17] which will supply chilled water for the air-conditioning of buildings in the area through pipes housed within the Common Services Tunnel in Marina Bay. The second district cooling ...
Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in "tons" (of refrigeration). Many manufacturers also specify capacity in Btu/h, especially when specifying the performance of smaller equipment.
