More About Petersburg, VA
Petersburg is an independent city in the Commonwealth of Virginia in the United States. As of the 2010 census, the population was 32,420.[5] The Bureau of Economic Analysis combines Petersburg (along with the city of Colonial Heights) with Dinwiddie County for statistical purposes. It is located on the Appomattox River (a tributary of the longer larger James River flowing east to meet the southern mouth of the Chesapeake Bay at the Hampton Roads harbor and the Atlantic Ocean). The city is just 21 miles (34 km) south of the historic commonwealth (state) capital city of Richmond. The city’s unique industrial past and its location as a transportation hub combined to create wealth for Virginia and the Middle Atlantic and Upper South regions of the nation.
Early in the colonial era of the 18th century, Petersburg was the final destination on the Upper Appomattox Canal Navigation System because of its location on the Appomattox River with its connection to the James River to the east at the Atlantic Seaboard fall line (the head of navigation of rivers on the U.S. East Coast) and the tying in with the James River shipping traffic was a strategic place for transportation and commercial activities. It connected commerce as far inland as Farmville, Virginia at the foothills of the Blue Ridge and the Appalachian Mountains chain, to shipping further east into the Chesapeake Bay and North Atlantic Ocean.[6] For similar reasons, 17th century era Fort Henry was built at the order of the Virginia House of Burgesses at Petersburg in 1645 to protect the river traffic.
Space pressure can be either favorable or unfavorable with respect to outside the room. Positive pressure happens when there is more air being supplied than exhausted, and prevails to decrease the seepage of outdoors pollutants. Natural ventilation is an essential consider lowering the spread of air-borne health problems such as tuberculosis, the acute rhinitis, influenza and meningitis.
Natural ventilation requires little maintenance and is low-cost. An air conditioning system, or a standalone air conditioning unit, provides cooling and humidity control for all or part of a structure. Air conditioned buildings typically have sealed windows, due to the fact that open windows would work against the system intended to preserve constant indoor air conditions.
The percentage of return air made up of fresh air can generally be manipulated by adjusting the opening of this vent. Common fresh air consumption is about 10%. [] Air conditioning and refrigeration are provided through the removal 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 horsepower is sufficient for the area being cooled. Underpowered cooling system will result in power wastage and inefficient usage. Appropriate horse power is required for any a/c set up. The refrigeration cycle uses 4 essential elements to cool. The system refrigerant begins its cycle in a gaseous state.
From there it goes into 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 phase. An (likewise called metering device) manages the refrigerant liquid to flow at the appropriate rate. The liquid refrigerant is returned to another heat exchanger where it is enabled to evaporate, hence the heat exchanger is typically called an evaporating coil or evaporator.
At the same time, heat is soaked up from inside and moved outdoors, resulting in cooling of the building. In variable environments, the system might include a reversing valve that changes from heating in winter season to cooling in summer season. By reversing the flow of refrigerant, the heatpump refrigeration cycle is changed from cooling to heating or vice versa.
Free cooling systems can have extremely high effectiveness, and are in some cases integrated with seasonal thermal energy storage so that the cold of winter season can be utilized for summertime air conditioning. Common storage mediums are deep aquifers or a natural underground rock mass accessed through a cluster of small-diameter, heat-exchanger-equipped boreholes.
The heatpump is added-in because the storage functions as a heat sink when the system is in cooling (instead of charging) mode, triggering the temperature level to gradually increase during the cooling season. Some systems consist of an “economizer mode”, which is often called a “free-cooling mode”. When economizing, the control system will open (fully or partly) the outdoors air damper and close (totally or partially) the return air damper.
When the outside air is cooler than the demanded cool air, this will allow the need to be fulfilled without utilizing the mechanical supply of cooling (typically chilled water or a direct growth “DX” system), 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 enter the economizer mode. Central, “all-air” air-conditioning systems (or package systems) with a combined outside condenser/evaporator system are typically set up in North American homes, offices, and public buildings, but are difficult to retrofit (set up in a building that was not designed to receive it) because of the bulky air ducts needed.
An alternative to packaged systems is the usage of different indoor and outside coils in split systems. Split systems are preferred and extensively utilized around the world except in North America. In North America, split systems are frequently seen in residential applications, however they are getting popularity in small industrial buildings.
The benefits of ductless air conditioning systems include simple setup, no ductwork, higher zonal control, flexibility of control and peaceful operation. [] In space conditioning, the duct losses can represent 30% of energy consumption. Using minisplit can lead to energy savings in area conditioning as there are no losses connected with ducting.
Indoor units with directional vents mount onto walls, suspended from ceilings, or fit into the ceiling. Other indoor systems install inside the ceiling cavity, so that short lengths of duct handle air from the indoor unit to vents or diffusers around the spaces. Split systems are more effective and the footprint is usually smaller than the package systems.
