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.

Room pressure can be either positive or unfavorable with respect to outside the space. Positive pressure takes place when there is more air being provided than exhausted, and prevails to lower the infiltration of outdoors contaminants. Natural ventilation is a key consider minimizing the spread of air-borne diseases such as tuberculosis, the acute rhinitis, influenza and meningitis.

Natural ventilation requires little maintenance and is economical. An a/c system, or a standalone air conditioner, provides cooling and humidity control for all or part of a building. Air conditioned structures often have sealed windows, because open windows would work against the system intended to maintain continuous indoor air conditions.

The percentage of return air made up of fresh air can generally be manipulated by adjusting the opening of this vent. Normal fresh air consumption has to do with 10%. [] Cooling and refrigeration are provided through the removal of heat. Heat can be removed through radiation, convection, or conduction. Refrigeration conduction media such as water, air, ice, and chemicals are described as refrigerants.

It is imperative that the a/c horsepower is adequate for the location being cooled. Underpowered a/c system will result in power waste and inefficient usage. Sufficient horsepower is required for any air conditioner set up. The refrigeration cycle utilizes four important components to cool. The system refrigerant begins 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 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 returned to another heat exchanger where it is permitted to vaporize, for this reason the heat exchanger is typically called an evaporating coil or evaporator.

While doing so, heat is taken in from indoors and transferred outdoors, resulting in cooling of the building. In variable climates, the system might include a reversing valve that changes from heating in winter to cooling in summertime. By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa.

Free cooling systems can have extremely high performances, and are often combined with seasonal thermal energy storage so that the cold of winter can be used for summer a/c. 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 functions as a heat sink when the system is in cooling (as opposed to charging) mode, triggering the temperature to slowly increase throughout the cooling season. Some systems include an “economizer mode”, which is in some cases called a “free-cooling mode”. When economizing, the control system will open (totally or partially) the outdoors air damper and close (fully or partially) the return air damper.

When the outside air is cooler than the demanded cool air, this will enable the demand to be met without using the mechanical supply of cooling (generally chilled water or a direct growth “DX” unit), hence saving 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 enter the economizer mode. Central, “all-air” air-conditioning systems (or plan systems) with a combined outdoor condenser/evaporator unit are frequently installed in North American homes, workplaces, and public buildings, but are tough to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required.

An alternative to packaged systems is the use of different indoor and outside coils in split systems. Split systems are preferred and widely used around the world except in The United States and Canada. In The United States and Canada, split systems are usually seen in domestic applications, but they are gaining popularity in small commercial buildings.

The advantages of ductless cooling systems consist of easy installation, no ductwork, higher zonal control, flexibility of control and peaceful operation. [] In area conditioning, the duct losses can represent 30% of energy consumption. The use of minisplit can result in energy savings in area 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 short lengths of duct deal with air from the indoor unit to vents or diffusers around the rooms. Split systems are more efficient and the footprint is typically smaller than the plan systems.
