More About Opelika, AL
Opelika (pronounced /ˌoʊpəˈlaɪkə/ OH-pə-LY-kə) is a city in and the county seat of Lee County in the east central part of the U.S. state of Alabama.[5] It is a principal city of the Auburn-Opelika Metropolitan Area. As of the 2010 census, the population of Opelika was 26,401,[3] and in 2018 the estimated population was 30,555.[4] The Auburn-Opelika, AL MSA with a population of 150,933, along with the Columbus, Georgia metropolitan area, comprises the Greater Columbus combined statistical area, a region home to 501,649 residents.
The first white settlers in the area now known as Opelika arrived in the late 1830s and established a community called Lebanon. After the removal of the native Creek (Muscogee) peoples by federal troops in 1836-37, the area became known as “Opelika.” This word taken from the Muskogee language means “large swamp”.
Room pressure can be either positive or unfavorable with regard to outside the space. Positive pressure happens when there is more air being supplied than tired, and is typical to reduce the seepage of outside impurities. Natural ventilation is a key factor in lowering the spread of airborne illnesses such as tuberculosis, the acute rhinitis, influenza and meningitis.
Natural ventilation needs little maintenance and is affordable. An air conditioning system, or a standalone air conditioner, provides cooling and humidity control for all or part of a structure. Air conditioned structures typically have actually sealed windows, due to the fact that open windows would work versus the system planned to keep consistent indoor air conditions.
The percentage of return air comprised of fresh air can typically be controlled by changing the opening of this vent. Normal fresh air consumption has to do with 10%. [] Air conditioning and refrigeration are supplied through the elimination of heat. Heat can be eliminated through radiation, convection, or conduction. Refrigeration conduction media such as water, air, ice, and chemicals are described as refrigerants.

It is necessary that the air conditioning horse power is adequate for the location being cooled. Underpowered a/c system will result in power waste and inefficient usage. Appropriate horse power is needed for any air conditioner set up. The refrigeration cycle uses four essential elements to cool. The system refrigerant starts its cycle in a gaseous state.
From there it gets in a heat exchanger (sometimes called a condensing coil or condenser) where it loses energy (heat) to the outdoors, cools, and condenses into its liquid stage. An (also called metering gadget) regulates the refrigerant liquid to stream at the appropriate rate. The liquid refrigerant is gone back to another heat exchanger where it is enabled to evaporate, thus the heat exchanger is often called an evaporating coil or evaporator.
In the process, heat is soaked up from inside and transferred outdoors, leading to cooling of the structure. In variable climates, the system might include a reversing valve that changes from heating in winter to cooling in summer. By reversing the circulation of refrigerant, the heat pump refrigeration cycle is altered from cooling to heating or vice versa.
Free cooling systems can have really high performances, and are in some cases integrated with seasonal thermal energy storage so that the cold of winter season can be used for summer a/c. Typical storage mediums are deep aquifers or a natural underground rock mass accessed through a cluster of small-diameter, heat-exchanger-equipped boreholes.
The heat pump is added-in because the storage acts as a heat sink when the system remains in cooling (rather than charging) mode, triggering the temperature to gradually increase during the cooling season. Some systems consist of an “economizer mode”, which is in some cases called a “free-cooling mode”. When economizing, the control system will open (totally or partially) the outside air damper and close (totally or partially) the return air damper.
When the outside air is cooler than the required cool air, this will allow the demand to be fulfilled without using the mechanical supply of cooling (normally chilled water or a direct expansion “DX” system), therefore saving energy. The control system can compare the temperature of the outdoors air vs.
In both cases, the outside air needs to be less energetic than the return air for the system to enter the economizer mode. Central, “all-air” air-conditioning systems (or plan systems) with a combined outdoor condenser/evaporator unit are typically installed in North American homes, workplaces, and public structures, but are challenging to retrofit (set up in a structure that was not created to receive it) because of the bulky duct needed.

An option to packaged systems is making use of different indoor and outside coils in split systems. Split systems are preferred and commonly utilized around the world other than in North America. In The United States and Canada, divided systems are frequently seen in residential applications, but they are gaining appeal in small business buildings.
The advantages of ductless air conditioning systems consist of simple setup, no ductwork, higher zonal control, versatility of control and peaceful operation. [] In space conditioning, the duct losses can represent 30% of energy intake. The use of minisplit can result in energy cost savings in space conditioning as there are no losses related to ducting.
Indoor systems with directional vents install onto walls, suspended from ceilings, or fit into the ceiling. Other indoor units mount inside the ceiling cavity, so that brief lengths of duct manage air from the indoor system to vents or diffusers around the spaces. Split systems are more efficient and the footprint is normally smaller sized than the plan systems.
