An air cooler is any device for cooling the air inside a building, room, or vehicle. [1]. Air coolers are used in thermally insulated casings to form refrigerators A refrigerator is a cooling appliance comprising a thermally insulated compartment and a heat pump—chemical or mechanical means—to transfer heat from it to the external environment, cooling the contents to a temperature below ambient. Cooling is a popular food storage technique in developed countries and works by decreasing the reproduction and are also used in buildings to cool rooms. In buildings they are only required when the building itself is not constructed so that it is able to dissipate enough heat. Methods to construct buildings in such a fashion that additional air coolers are not required are eg Earth sheltering Earth sheltering is the architectural practice of using earth against building walls for external thermal mass, to reduce heat loss, and to easily maintain a steady indoor air temperature. Earth sheltering is popular in modern times among advocates of passive solar and sustainable architecture, but has been around for nearly as long as humans have or specific building designs [2].
Devices
An absorption air cooler.Several devices exist, these include:
- Wet air coolers Evaporative cooling is especially well suited for climates where the air is hot and humidity is low. For example, in the United States, the western/mountain states are good locations, with swamp coolers very prevalent in cities like Denver, Salt Lake City, Albuquerque, El Paso, Tucson, and Fresno where sufficient water is available. Evaporative
- Dry air coolers
- Absorption air coolers
- Deep water source cooling system
- Ground-coupled heat exchanger A ground-coupled heat exchanger is an underground heat exchanger loop that can capture or dissipate heat to or from the ground. They use the Earth's near constant subterranean temperature to warm or cool air or other fluids for residential, agricultural or industrial uses. If building air is blown through the heat exchanger for heat recovery
- Air and water-coupled heat pumps A heat pump is a machine or device that moves heat from one location to another location (the 'sink' or 'heat sink') using mechanical work. Most heat pump technology moves heat from a low temperature heat source to a higher temperature heat sink. Common examples are food refrigerators and freezers, air conditioners, and reversible-cycle heat pumps
Coolers outfitted with extras as heating,and dehumidifying are called Air conditioners An air conditioner is a home appliance, system, or mechanism designed to dehumidify and extract heat from an area. The cooling is done using a simple refrigeration cycle. In construction, a complete system of heating, ventilation, and air conditioning is referred to as "HVAC". Its purpose, in a building or an automobile, is to provide.
