With ac, keep in mind that comfort is exactly what you're after, not really a specific air temperature. To lessen ac needs, one technique is to boost your comfort threshold. Dressing in light clothing can help to some degree during the sunshine.
More importantly, ceiling-mounted paddle fans or portable room fans can offer airflow that evaporates moisture from your skin so that you'll be comfortable in a higher air temperature. Using the airflow generated with a paddle fan, enhanced comfort threshold for most people could be increased from about 75°F to as much as 82°F.
Note that fans don't actually lower the environment temperature; in fact, they enhance the temperature slightly in the motor's waste heat. So switch off fans whenever you leave an area.
Whenever you can't maintain adequate comfort by blocking sunlight, ventilating during the night, and taking advantage of fans to boost your comfort threshold, the final resort is mechanical ac.
Most mechanical air conditioning units function a lot like your refrigerator, except that part of the unit is situated outside your house. These units make use of a refrigerant cycle in which a unique refrigerant fluid is alternately compressed and evaporated to extract heat from the inside your home and dump it to the air outside.
Having a whole-house (central) ac or electric, it comes with an outside compressor in which the refrigerant is compressed from gas to liquid in a procedure that raises its temperature and allows that heat to become used in the exterior air. Indoors is definitely an evaporator in which the refrigerant changes phase from liquid to gas, cool down in the process.
A blower attached to the evaporator circulates cooled air at home. Having a window-mounted or through-the-wall room ac, both of these components are more closely connected, however the basic operation is identical.
Unfortunately, refrigerant-cycle air conditioning units require quite a lot of one's to maintain your house cool. Many of them also have a refrigerant that damages our planet's protective stratospheric ozone layer. These HCFCs are slated to become eliminated within the next several decades. Some air conditioning units with ozone-safe refrigerants happen to be on the market.
When choosing a refrigerant-cycle ac, search for an energyefficient model. The power efficiency of whole-house air conditioning units shows up because the seasonal energy efficiency rating (SEER); locate a model having a SEER with a minimum of 14. The power efficiency of room air conditioning units is offered in a power efficiency rating (EER). Locate a model by having an EER with a minimum of 10.5. In humid climates, when selecting an aura conditioner, also consider how effectively the model removes moisture.
Ask a salesman or your ac contractor concerning the moisture removal capacity of various models and that which you need for your climate.
In dry climates, an evaporative cooler (swamp cooler) could be a great option to a regular, refrigerant-cycle ac. By evaporating tiny droplets of water in an airstream, an evaporative cooler uses much less energy for cooling the environment than standard air conditioning units, although most models use a substantial quantity of water. This method isn't effective in humid climates.
