More About Laveen, AZ
Laveen /ləˈviːn/ is an “urban village” within the city of Phoenix in Maricopa County, Arizona, United States, situated eight miles (13 km) southwest of Downtown Phoenix between South Mountain and the confluence of the Gila and Salt rivers.[1] Parts of Laveen constitute an unincorporated community in Maricopa County, while the remainder falls within the city limits of Phoenix, constituting the city’s “Laveen Village”. Laveen Village is split between District 7 and District 8, both notable as minority-majority districts for the city. Although Laveen has been home to “pastoral alfalfa, cotton, and dairy farms”[2] since the 1880s, housing and commercial developments have been increasingly urbanizing the area.
The Laveen area was first settled by farmers and dairymen in 1884. Despite its proximity to Phoenix, the community was isolated from its larger neighbor by the Salt River, which until the Roosevelt Dam was completed in 1911 carried water year-round. The only bridged crossing was at Central Avenue, more than six miles (10 km) away.[3][4] Because of its isolation, like the rest of south Phoenix early Laveen was autonomous of Phoenix and became relatively self-sufficient, supporting two general stores, a barbershop, repair garage, two pool halls, and a building for the Laveen Women’s Club. These businesses served as important gathering places for the greater Laveen community, which includes modern south Phoenix and the neighboring Gila River Indian Community (GRIC).[3]
Space pressure can be either favorable or negative with regard to outside the space. Positive pressure occurs when there is more air being provided than exhausted, and is common to minimize the seepage of outside pollutants. Natural ventilation is an essential factor in lowering the spread of air-borne illnesses such as tuberculosis, the cold, influenza and meningitis.
Natural ventilation requires little maintenance and is low-cost. A cooling system, or a standalone air conditioning unit, supplies cooling and humidity control for all or part of a structure. Air conditioned buildings typically have actually sealed windows, since open windows would work versus the system intended to maintain consistent indoor air conditions.
The percentage of return air made up of fresh air can usually be controlled by changing the opening of this vent. Common fresh air consumption is about 10%. [] Air conditioning and refrigeration are provided through the elimination of heat. Heat can be gotten rid of through radiation, convection, or conduction. Refrigeration conduction media such as water, air, ice, and chemicals are described as refrigerants.

It is necessary that the air conditioning horse power is sufficient for the location being cooled. Underpowered air conditioning system will result in power waste and inefficient usage. Appropriate horse power is required for any air conditioning unit installed. The refrigeration cycle uses 4 necessary aspects to cool. The system refrigerant starts 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 phase. An (likewise called metering device) controls the refrigerant liquid to flow at the appropriate rate. The liquid refrigerant is gone back to another heat exchanger where it is enabled to vaporize, hence the heat exchanger is typically called an evaporating coil or evaporator.
In the process, heat is taken in from inside and moved outdoors, resulting in cooling of the structure. In variable climates, the system might 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 efficiencies, and are sometimes combined with seasonal thermal energy storage so that the cold of winter can be used for summer cooling. Common storage mediums are deep aquifers or a natural underground rock mass accessed through a cluster of small-diameter, heat-exchanger-equipped boreholes.
The heatpump is added-in since the storage serves as a heat sink when the system remains in cooling (rather than charging) mode, causing the temperature level to gradually increase during 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 (fully or partly) the outside air damper and close (fully or partly) the return air damper.
When the outside air is cooler than the required cool air, this will permit the demand to be met without using the mechanical supply of cooling (generally chilled water or a direct growth “DX” system), 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 outside condenser/evaporator system are typically installed in North American houses, offices, and public buildings, but are difficult to retrofit (set up in a building that was not designed to get it) since of the large duct required.

An alternative to packaged systems is making use of separate indoor and outside coils in split systems. Split systems are preferred and commonly utilized around the world except in The United States and Canada. In North America, divided systems are frequently seen in property applications, but they are acquiring popularity in small commercial buildings.
The advantages of ductless a/c systems include easy installation, no ductwork, higher zonal control, flexibility of control and quiet operation. [] In area conditioning, the duct losses can account for 30% of energy usage. The usage of minisplit can result in energy cost savings in area conditioning as there are no losses associated with 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 brief lengths of duct manage air from the indoor system to vents or diffusers around the spaces. Split systems are more effective and the footprint is usually smaller than the plan systems.
