More About Harvey, LA
Harvey is a census-designated place (CDP) in Jefferson Parish, Louisiana, United States. Harvey is on the south side (referred to as the “West Bank”) of the Mississippi River, within the New Orleans–Metairie–Kenner Metropolitan Statistical Area. The majority-minority population was 20,348 at the 2010 census,[1] down from 22,226 at the 2000 census.
Harvey is located east of the Intracoastal Canal on the Mississippi River, at coordinates 29°53′28″N 90°04′09″W / 29.89111°N 90.06917°W / 29.89111; -90.06917. It is bordered to the east by Gretna, to the west by Marrero, to the southwest by Woodmere, and to the north, across the Mississippi, by New Orleans. The closest highway crossing of the river is the Crescent City Connection 4 miles (6 km) northeast of Harvey.
Space pressure can be either positive or unfavorable with respect to outside the room. Positive pressure occurs when there is more air being supplied than exhausted, and is common to minimize the seepage of outdoors pollutants. Natural ventilation is an essential consider minimizing the spread of airborne health problems such as tuberculosis, the cold, influenza and meningitis.
Natural ventilation needs little maintenance and is inexpensive. An air conditioning system, or a standalone air conditioner, supplies cooling and humidity control for all or part of a structure. Air conditioned structures often have actually sealed windows, due to the fact that open windows would work against the system planned to keep constant indoor air conditions.
The percentage of return air comprised of fresh air can normally be manipulated by adjusting the opening of this vent. Typical fresh air consumption is about 10%. [] Cooling 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 cooling horse power suffices for the location being cooled. Underpowered a/c system will cause power wastage and inefficient usage. Sufficient horsepower is needed for any air conditioning system installed. The refrigeration cycle utilizes 4 essential components to cool. The system refrigerant starts its cycle in a gaseous state.
From there it enters a heat exchanger (in some cases called a condensing coil or condenser) where it loses energy (heat) to the outdoors, cools, and condenses into its liquid stage. An (likewise called metering device) controls the refrigerant liquid to stream at the correct rate. The liquid refrigerant is gone back to another heat exchanger where it is allowed to evaporate, for this reason the heat exchanger is typically called an evaporating coil or evaporator.
While doing so, heat is soaked up from indoors and moved outdoors, leading to cooling of the structure. In variable environments, the system may include a reversing valve that changes from heating in winter to cooling in summer. By reversing the circulation of refrigerant, the heatpump refrigeration cycle is altered from cooling to heating or vice versa.
Free cooling systems can have very high efficiencies, and are often combined with seasonal thermal energy storage so that the cold of winter season can be utilized for summer season air conditioning. Typical storage mediums are deep aquifers or a natural underground rock mass accessed by means of a cluster of small-diameter, heat-exchanger-equipped boreholes.
The heatpump is added-in due to the fact that the storage functions as a heat sink when the system remains in cooling (instead of charging) mode, triggering the temperature to slowly increase during 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 (completely or partially) the outside air damper and close (fully or partly) the return air damper.
When the outdoors air is cooler than the demanded cool air, this will allow the demand to be fulfilled without using the mechanical supply of cooling (usually cooled water or a direct expansion “DX” unit), therefore 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 bundle systems) with a combined outside condenser/evaporator unit are frequently set up in North American houses, workplaces, and public buildings, however are difficult to retrofit (install in a structure that was not developed to receive it) since of the bulky duct needed.
An option to packaged systems is the usage 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, split systems are usually seen in property applications, but they are getting popularity in little commercial buildings.
The advantages of ductless cooling systems include simple installation, no ductwork, higher zonal control, versatility of control and quiet operation. [] In space conditioning, the duct losses can represent 30% of energy consumption. Using minisplit can lead to energy cost savings in space conditioning as there are no losses connected with ducting.
Indoor systems with directional vents mount onto walls, suspended from ceilings, or fit into the ceiling. Other indoor systems mount inside the ceiling cavity, so that short lengths of duct deal with 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.
