More About Chevy Chase, MD
Chevy Chase is the name of both a town and an unincorporated census-designated place (Chevy Chase (CDP), Maryland) that straddle the northwest border of Washington, D.C. and Montgomery County, Maryland, United States. Several settlements in the same area of Montgomery County and one neighborhood of Washington include “Chevy Chase” in their names. These villages, the town, and the CDP share a common history and together form a larger community colloquially referred to as “Chevy Chase”.
Primarily a residential suburb, Chevy Chase adjoins Friendship Heights, a popular shopping district. It includes the National 4-H Youth Conference Center, which hosts the National 4-H Conference, an event for 4-Hers throughout the nation to attend, and the National Science Bowl annually in either late April or early May.[1] Chevy Chase is also the home of the Chevy Chase Club and Columbia Country Club, whose members include many prominent politicians and Washingtonians.[2]
Space pressure can be either favorable or unfavorable with regard to outside the space. Positive pressure takes place when there is more air being supplied than tired, and is typical to reduce the infiltration of outdoors contaminants. Natural ventilation is an essential factor in lowering the spread of air-borne illnesses such as tuberculosis, the typical cold, influenza and meningitis.
Natural ventilation requires little upkeep and is economical. An air conditioning system, or a standalone a/c unit, provides cooling and humidity control for all or part of a structure. Air conditioned structures typically have sealed windows, since open windows would work versus the system planned to preserve continuous indoor air conditions.
The portion of return air comprised of fresh air can typically be controlled by changing the opening of this vent. Common fresh air consumption has to do with 10%. [] A/c and refrigeration are offered 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 referred to as refrigerants.

It is necessary that the a/c horse power is sufficient for the area being cooled. Underpowered a/c system will lead to power waste and ineffective usage. Appropriate horsepower is required for any a/c unit set up. The refrigeration cycle utilizes 4 important elements to cool. The system refrigerant begins its cycle in a gaseous state.
From there it goes into a heat exchanger (often 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) manages the refrigerant liquid to flow at the correct rate. The liquid refrigerant is gone back to another heat exchanger where it is enabled to vaporize, for this reason the heat exchanger is often called an evaporating coil or evaporator.
While doing so, heat is taken in from inside and moved outdoors, leading to cooling of the structure. In variable climates, the system may consist of a reversing valve that switches from heating in winter to cooling in summertime. By reversing the flow of refrigerant, the heat pump refrigeration cycle is altered from cooling to heating or vice versa.
Free cooling systems can have very high performances, and are sometimes combined with seasonal thermal energy storage so that the cold of winter season can be utilized for summer season cooling. 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 heat pump 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 slowly 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 partly) the outside air damper and close (fully or partly) the return air damper.
When the outside air is cooler than the demanded cool air, this will permit the need to be met without using the mechanical supply of cooling (generally chilled water or a direct expansion “DX” unit), hence saving energy. The control system can compare the temperature 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 bundle systems) with a combined outdoor condenser/evaporator system are typically set up in North American homes, workplaces, and public structures, however are difficult to retrofit (set up in a building that was not developed to receive it) because of the bulky air ducts required.

An alternative to packaged systems is the use of separate indoor and outdoor coils in split systems. Split systems are chosen and extensively used around the world except in North America. In North America, split systems are usually seen in domestic applications, but they are gaining popularity in little commercial buildings.
The advantages of ductless cooling systems consist of easy installation, no ductwork, higher zonal control, versatility of control and quiet operation. [] In space conditioning, the duct losses can represent 30% of energy usage. Making use of minisplit can lead to energy savings in space conditioning as there are no losses related to ducting.
Indoor units with directional vents install onto walls, suspended from ceilings, or fit into the ceiling. Other indoor systems mount inside the ceiling cavity, so that brief lengths of duct manage air from the indoor system to vents or diffusers around the rooms. Split systems are more effective and the footprint is usually smaller sized than the bundle systems.
