More About Tappahannock, VA
Tappahannock is the oldest town in Essex County, Virginia, United States. The population was 2,375 at the 2010 census,[5] up from 2,068 at the 2000 census. Located on the Rappahannock River, Tappahannock is the county seat of Essex County.[6] Its name comes from an Algonquian language word lappihanne (also noted as toppehannock), meaning “Town on the rise and fall of water” or “where the tide ebbs and flows.” In 1608 John Smith landed in Tappahannock and fought with the local Rappahannock tribe. After defeating them, he later made peace.[7][8][9][10]
In 1682 a local man, Jacob Hobbs, established a trading post in the now extinct Rappahannock County[11] (in the vicinity of present-day Tappahannock). This area became known as “Hobbs Hole”. The town comprised 50 acres (20 ha) divided into half-acre squares.[12] The port was established at Hobbs Hole and called “New Plymouth”,[12] later changed back to the Native American name “Tappahannock”. As part of the Tobacco Inspection Act of 1730 public warehouses for inspection and exportation of tobacco were established at Hobbs Hole.
Space pressure can be either positive or negative with respect to outside the space. Favorable pressure happens when there is more air being supplied than exhausted, and prevails to lower the infiltration of outside pollutants. Natural ventilation is an essential consider reducing the spread of airborne diseases such as tuberculosis, the acute rhinitis, influenza and meningitis.
Natural ventilation requires little maintenance and is inexpensive. An a/c system, or a standalone a/c unit, offers cooling and humidity control for all or part of a building. Air conditioned structures frequently have sealed windows, since open windows would work against the system intended to keep constant indoor air conditions.
The percentage of return air made up of fresh air can generally be controlled by adjusting the opening of this vent. Typical fresh air consumption has to do with 10%. [] A/c and refrigeration are provided through the elimination of heat. Heat can be removed through radiation, convection, or conduction. Refrigeration conduction media such as water, air, ice, and chemicals are referred to as refrigerants.
It is crucial that the cooling horse power is adequate for the area being cooled. Underpowered a/c system will cause power wastage and ineffective use. Sufficient horse power is needed for any air conditioning system set up. The refrigeration cycle uses 4 vital components 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 phase. An (also 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 allowed to vaporize, thus the heat exchanger is often called an evaporating coil or evaporator.
At the same time, heat is absorbed from inside and moved outdoors, resulting in cooling of the building. In variable environments, the system might include a reversing valve that switches from heating in winter season to cooling in summer season. By reversing the circulation of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa.
Free cooling systems can have very high efficiencies, and are in some cases integrated with seasonal thermal energy storage so that the cold of winter can be utilized for summertime air conditioning. Common 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 since the storage acts as a heat sink when the system remains in cooling (as opposed to charging) mode, causing the temperature to gradually increase throughout the cooling season. Some systems consist of an “economizer mode”, which is in some cases called a “free-cooling mode”. When saving money, the control system will open (completely or partly) the outside air damper and close (fully or partially) the return air damper.
When the outside air is cooler than the demanded cool air, this will allow the demand to be met without using the mechanical supply of cooling (normally chilled water or a direct expansion “DX” unit), hence conserving energy. The control system can compare the temperature level of the outside air vs.
In both cases, the outside air must be less energetic than the return air for the system to go into the economizer mode. Central, “all-air” air-conditioning systems (or plan systems) with a combined outdoor condenser/evaporator system are typically installed in North American homes, workplaces, and public buildings, however are tough to retrofit (install in a structure that was not designed to receive it) due to the fact that of the large air ducts required.
An option to packaged systems is making use of separate indoor and outside coils in split systems. Split systems are chosen and extensively used worldwide except in North America. In North America, split systems are most often seen in property applications, but they are acquiring appeal in small business structures.
The advantages of ductless cooling systems consist of easy setup, no ductwork, higher zonal control, flexibility of control and quiet operation. [] In area conditioning, the duct losses can represent 30% of energy usage. Using minisplit can lead to energy cost savings in area conditioning as there are no losses related to ducting.
Indoor units with directional vents install onto walls, suspended from ceilings, or suit the ceiling. Other indoor units mount inside the ceiling cavity, so that short lengths of duct manage air from the indoor unit to vents or diffusers around the rooms. Split systems are more effective and the footprint is normally smaller than the plan systems.
