More About Gretna, NE
Gretna is a city in Sarpy County, Nebraska, United States. The population was 4,441 at the 2010 census.
Gretna started shortly after the Burlington Railroad built a short line between Omaha and Ashland in the summer of 1886.[5] Advent of the village of Gretna on this new laid rail line was the cue for the exit of the nearby trading post of Forest City, which had existed since 1856. In its day, Forest City, located 2.5 miles southwest of where Gretna now stands, was a flourishing and busy place, but it was doomed by the rail road which passed it by. The only marker that exists today to show the site of old Forest City is the cemetery (Holy Sepulcher) which is located a little to the east of what was the center of activity in the settlement. Names that were prominent in the beginnings of Forest City were the families of William Langdon, John Thomas and John Conner.
Space pressure can be either positive or unfavorable with regard to outside the space. Positive pressure happens when there is more air being supplied than tired, and prevails to decrease the infiltration of outside contaminants. Natural ventilation is a key aspect in decreasing the spread of airborne diseases such as tuberculosis, the acute rhinitis, influenza and meningitis.
Natural ventilation needs little maintenance and is inexpensive. An a/c system, or a standalone a/c unit, supplies cooling and humidity control for all or part of a structure. Air conditioned buildings frequently have actually sealed windows, because open windows would work against the system meant to maintain constant indoor air conditions.
The portion of return air comprised of fresh air can usually be controlled by adjusting the opening of this vent. Normal fresh air consumption has to do with 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 referred to as refrigerants.

It is crucial that the air conditioning horse power suffices for the area being cooled. Underpowered a/c system will result in power waste and ineffective use. Sufficient horse power is required for any ac system set up. The refrigeration cycle uses four necessary components to cool. The system refrigerant begins its cycle in a gaseous state.
From there it goes into a heat exchanger (sometimes called a condensing coil or condenser) where it loses energy (heat) to the outdoors, cools, and condenses into its liquid stage. An (also called metering gadget) manages the refrigerant liquid to flow at the proper rate. The liquid refrigerant is gone back to another heat exchanger where it is permitted to vaporize, for this reason the heat exchanger is frequently called an evaporating coil or evaporator.
While doing so, heat is taken in from inside and transferred outdoors, resulting in cooling of the building. In variable environments, the system may consist of a reversing valve that changes from heating in winter season to cooling in summertime. 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 effectiveness, and are in some cases combined with seasonal thermal energy storage so that the cold of winter can be used for summer a/c. Typical 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 due to the fact that the storage functions as a heat sink when the system is in cooling (rather than charging) mode, causing the temperature to slowly increase throughout 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 (totally or partly) the outdoors air damper and close (fully or partly) the return air damper.
When the outdoors air is cooler than the required cool air, this will allow the need to be satisfied without utilizing the mechanical supply of cooling (usually chilled water or a direct growth “DX” unit), hence conserving energy. The control system can compare the temperature level of the outside air vs.
In both cases, the outdoors air should be less energetic than the return air for the system to get in the economizer mode. Central, “all-air” air-conditioning systems (or bundle systems) with a combined outdoor condenser/evaporator unit are often installed in North American homes, workplaces, and public structures, but are tough to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required.

An option to packaged systems is the usage of separate indoor and outdoor coils in split systems. Split systems are chosen and commonly used worldwide except in The United States and Canada. In The United States and Canada, split systems are most typically seen in domestic applications, but they are gaining popularity in little commercial structures.
The benefits of ductless cooling systems consist of easy setup, no ductwork, greater zonal control, versatility of control and peaceful operation. [] In area conditioning, the duct losses can account for 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 systems with directional vents mount onto walls, suspended from ceilings, or fit into the ceiling. Other indoor systems mount inside the ceiling cavity, so that short lengths of duct manage air from the indoor system to vents or diffusers around the rooms. Split systems are more efficient and the footprint is typically smaller than the package systems.
