In heating, ventilation, and air conditioning in winter months, large commercial buildings interior spaces may need cooling, even while perimeter spaces may need heating. [2] Free cooling is the production of chilled water without the use of a chiller, and can be used generally in the late fall, winter and early spring, in temperate zones. [3]
Cooling tower and water discharge of a nuclear power plant. Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion.
In a wet cooling tower (or open circuit cooling tower), the warm water can be cooled to a temperature lower than the ambient air dry-bulb temperature, if the air is relatively dry (see dew point and psychrometrics). As ambient air is drawn past a flow of water, a small portion of the water evaporates, and the energy required to evaporate that ...
Evaporative coolers, also known as swamp coolers, are environmentally friendly, cost-effective ways to make your home and outdoor areas more comfortable. A good evaporative cooler, used correctly ...
Air conditioning requires energy, and contributes to global warming – here are five ways of cooling which won't cost the planet. Air conditioning requires energy, and contributes to global ...
No air conditioning? Here are 14 methods for cooling your body and buffering your house from the outside heat.
Air conditioning applications are expected to rise. [30] However, this can be significantly reduced with the mass production of low-cost PDRCs for indoor space cooling. [7] [8] [91] A multilayer PDRC surface covering 10% of a building's roof can replace 35% of air conditioning used during the hottest hours of daytime. [7]
