More About Bethesda, MD
Bethesda is an unincorporated, census-designated place in southern Montgomery County, Maryland, United States, located just northwest of the U.S. capital of Washington, D.C. It takes its name from a local church, the Bethesda Meeting House (1820, rebuilt 1849), which in turn took its name from Jerusalem’s Pool of Bethesda.[2] The National Institutes of Health main campus and the Walter Reed National Military Medical Center are in Bethesda, as are a number of corporate and government headquarters.
As an unincorporated community, Bethesda has no official boundaries. The United States Census Bureau defines a census-designated place named Bethesda whose center is located at 38°59′N 77°7′W / 38.983°N 77.117°W / 38.983; -77.117. The United States Geological Survey has defined Bethesda as an area whose center is at 38°58′50″N 77°6′2″W / 38.98056°N 77.10056°W / 38.98056; -77.10056, slightly different from the Census Bureau’s definition. Other definitions are used by the Bethesda Urban Planning District, the United States Postal Service (which defines Bethesda to comprise the ZIP Codes 20810, 20811, 20813, 20814, 20815, 20816, and 20817), and other organizations. According to estimates released by the U.S. Census Bureau in 2013, the community had a total population of 63,374. Most of Bethesda’s residents are in Maryland Legislative District 15.
Space pressure can be either favorable or negative with regard to outside the room. Favorable pressure occurs when there is more air being supplied than tired, and prevails to lower the infiltration of outdoors pollutants. Natural ventilation is a key factor in decreasing the spread of airborne illnesses such as tuberculosis, the cold, influenza and meningitis.
Natural ventilation needs little upkeep and is inexpensive. An a/c system, or a standalone a/c, offers cooling and humidity control for all or part of a building. Air conditioned buildings frequently have actually sealed windows, because open windows would work versus the system meant to maintain continuous indoor air conditions.
The portion of return air made up of fresh air can typically be controlled by changing the opening of this vent. Common fresh air intake is about 10%. [] Air conditioning and refrigeration are offered 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 referred to as refrigerants.

It is crucial that the cooling horse power suffices for the area being cooled. Underpowered air conditioning system will lead to power wastage and inefficient use. Adequate horsepower is needed for any a/c installed. The refrigeration cycle uses 4 necessary elements to cool. The system refrigerant begins its cycle in a gaseous state.
From there it gets in a heat exchanger (in some cases called a condensing coil or condenser) where it loses energy (heat) to the outside, cools, and condenses into its liquid phase. An (also called metering device) manages the refrigerant liquid to flow at the proper rate. The liquid refrigerant is returned to another heat exchanger where it is allowed to vaporize, hence the heat exchanger is typically called an evaporating coil or evaporator.
In the process, heat is taken in from inside and transferred outdoors, leading to cooling of the structure. In variable environments, the system may include a reversing valve that switches from heating in winter to cooling in summertime. 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 efficiencies, and are in some cases integrated with seasonal thermal energy storage so that the cold of winter season can be utilized for summertime a/c. Typical 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 due to the fact that the storage acts as a heat sink when the system is in cooling (rather than charging) mode, triggering the temperature to gradually increase during the cooling season. Some systems include an “economizer mode”, which is sometimes called a “free-cooling mode”. When saving money, the control system will open (completely or partially) the outdoors air damper and close (totally or partially) the return air damper.
When the outdoors air is cooler than the required cool air, this will allow the demand to be fulfilled without utilizing the mechanical supply of cooling (normally cooled water or a direct expansion “DX” system), therefore conserving energy. The control system can compare the temperature of the outside air vs.
In both cases, the outside air should be less energetic than the return air for the system to go into the economizer mode. Central, “all-air” air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator system are often installed in North American homes, offices, and public structures, but are difficult to retrofit (set up in a structure that was not designed to receive it) due to the fact that of the large duct needed.

An alternative to packaged systems is the use of separate indoor and outside coils in split systems. Split systems are chosen and widely used worldwide other than in North America. In North America, divided systems are usually seen in property applications, but they are getting popularity in little industrial structures.
The benefits of ductless air conditioning systems consist of easy setup, no ductwork, higher zonal control, flexibility of control and peaceful operation. [] In area conditioning, the duct losses can account for 30% of energy consumption. Using minisplit can result in energy savings in space 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 units mount inside the ceiling cavity, so that short lengths of duct handle air from the indoor system to vents or diffusers around the rooms. Split systems are more effective and the footprint is typically smaller than the bundle systems.
