Windcatchers that cool by drawing air over water use the water as a heat reservoir, but if the air is dry, they are also cooling the air with evaporative cooling. [2] The heat in the air goes into evaporating some of the water, and will not be released until the water re-condenses. This is a very effective way of cooling dry air. [2] Simply ...
The closed loop system can be more effective cooling the air (during air temperature extremes) than an open system, since it cools and recools the same air. Open system: Outside air is drawn from a filtered air intake (Minimum Efficiency Reporting Value MERV 8+ air filter is recommended) to cool or preheat the air. The tubes are typically 30 m ...
AMCA Publication 511 - Certified Ratings Program - Product Rating Manual for Air Control Devices describes the certification procedures under which the AMCA International Certified Ratings Seal is granted for sound, air performance, air leakage, water penetration and wind driven rain for air control products.
New cars produced in the early 1990s contained the new refrigerant in their air conditioning systems. Owners of older cars with R-12 systems would either have to invest in an R-12 to R-134a conversion system, buy a new car, or find a qualified technician to recharge their older R-12 system. R-134a has been used in cars for almost 30 years.
Combining heating, cooling, and ventilating, the new air conditioning system for the Nash cars was called the "All-Weather Eye". [ 13 ] The 1954 Nash models were the first American automobiles to have a front-end, fully integrated heating, ventilating, and air-conditioning system.
Ventilative cooling is the use of natural or mechanical ventilation to cool indoor spaces. [1] The use of outside air reduces the cooling load and the energy consumption of these systems, while maintaining high quality indoor conditions; passive ventilative cooling may eliminate energy consumption.

Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. Air-cooled designs are far simpler than their liquid-cooled counterparts, which require a separate radiator , coolant reservoir, piping and pumps.
