More About Oxon Hill, MD
Oxon Hill is an unincorporated area and census-designated place (CDP) in southern Prince George’s County, Maryland, United States.[1] Oxon Hill is a suburb of Washington, located southeast of the downtown district and east of Alexandria, Virginia. It contains the new 300-acre (120 ha) National Harbor development on the shore of the Potomac River.
For the 1990 and 2000 censuses, the United States Census Bureau defined a census-designated place consisting of Oxon Hill and the adjacent community of Glassmanor, designated Oxon Hill-Glassmanor, for statistical purposes. As of the 2010 census, Oxon Hill was delineated separately and had a population of 17,722.[2]
Space pressure can be either favorable or negative with respect to outside the room. Positive pressure takes place when there is more air being supplied than exhausted, and is typical to lower the infiltration of outside impurities. Natural ventilation is a key aspect in decreasing the spread of air-borne health problems such as tuberculosis, the cold, influenza and meningitis.
Natural ventilation requires little upkeep and is inexpensive. An a/c system, or a standalone air conditioning unit, offers cooling and humidity control for all or part of a structure. Air conditioned structures typically have sealed windows, due to the fact that open windows would work versus the system planned to keep constant indoor air conditions.
The percentage of return air made up of fresh air can normally be manipulated by adjusting the opening of this vent. Normal fresh air intake has to do with 10%. [] Air conditioning and refrigeration are provided 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 essential that the a/c horse power suffices for the location being cooled. Underpowered a/c system will cause power waste and ineffective usage. Sufficient horsepower is needed for any ac system installed. The refrigeration cycle uses four essential elements to cool. The system refrigerant starts its cycle in a gaseous state.
From there it goes into a heat exchanger (often called a condensing coil or condenser) where it loses energy (heat) to the outside, cools, and condenses into its liquid stage. An (likewise called metering gadget) controls the refrigerant liquid to flow at the correct rate. The liquid refrigerant is gone back to another heat exchanger where it is allowed to evaporate, hence the heat exchanger is frequently called an evaporating coil or evaporator.
While doing so, heat is soaked up from inside your home and moved outdoors, leading to cooling of the building. In variable environments, the system may consist of a reversing valve that changes from heating in winter to cooling in summertime. By reversing the flow of refrigerant, the heatpump refrigeration cycle is altered from cooling to heating or vice versa.
Free cooling systems can have very high effectiveness, and are often combined with seasonal thermal energy storage so that the cold of winter season can be used for summer season cooling. Common storage mediums are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat-exchanger-equipped boreholes.
The heat pump is added-in since the storage serves as a heat sink when the system remains in cooling (instead of charging) mode, triggering the temperature level to gradually increase throughout the cooling season. Some systems include an “economizer mode”, which is in some cases called a “free-cooling mode”. When saving money, the control system will open (fully or partly) the outside air damper and close (fully or partially) the return air damper.
When the outdoors air is cooler than the required cool air, this will enable the demand to be met without utilizing the mechanical supply of cooling (normally cooled water or a direct growth “DX” unit), thus conserving energy. The control system can compare the temperature of the outdoors air vs.
In both cases, the outdoors air should be less energetic than the return air for the system to get in the economizer mode. Central, “all-air” air-conditioning systems (or package systems) with a combined outside condenser/evaporator system are often set up in North American homes, offices, and public buildings, however are hard to retrofit (install in a building that was not created to get it) due to the fact that of the large duct required.

An option to packaged systems is the use of separate indoor and outdoor coils in split systems. Split systems are chosen and widely utilized around the world other than in North America. In North America, split systems are frequently seen in residential applications, however they are gaining popularity in little commercial structures.
The advantages of ductless a/c systems include simple setup, no ductwork, greater zonal control, versatility of control and quiet operation. [] In area conditioning, the duct losses can account for 30% of energy consumption. Making use of minisplit can result in energy savings in space conditioning as there are no losses related to ducting.
Indoor systems with directional vents mount 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 effective and the footprint is usually smaller than the package systems.
