Air Conditioning in Residential Building 2Executive summaryBuilding Science Corporation directly works with David weekly homed to redesign three plans of the current floor to locate air conditioned systems in the conditioned place. The importance of this research paper is to develop a cheap design for moving air conditioned system into the spaceconditioned. Also building Science Corporation conducted the analysis of energy to calculate the most approach which is economical for increasing the performance of energy of the productions of houses in future. The constructors’ wishes to improve the package upgraded that will enable the continuous transition as mandated in the new codes.Building Science Corporation and the constructor develop a strategy design that employs system of dropped ceilings and coffers for ductwork moving to the conditioned space from the vented attic. The designed development of the duct coffers in the attic space enables David weekly homes to embrace the approach of the location of ductwork in the space conditioned, in the stockof available houses without using dropped ceilings. The constructor recognizes that dropped ceilings without coffers would be an economic plan for duct location. The builder identifies this design as a negative effects on aesthetics and could not be good-looking to the base customers and it's the most important development in the research as David's weekly home and its customers wish to avoid dropped ceilings[ CITATION Ame163 \l 1033 ]. The main contribution of the research is to give the alternative for working to builders who need to move their heating ventilation air conditioner systems into conditioned spaces without prolonged ceiling drop and a mechanical closet or even transforming it to full cathedralized attic not vented. Transferring the system air conditioning to within conditioned space caused in important energy saving towards the goal of achieving an energy saving of 50%. Moving air conditioning systems inside the space conditioned save 4 to 5% in the energy source use and decrease the system of energy rating at home. The additional upgrades of energy that was implemented are: improvements to ceiling, walls, air conditioner and heater of hot water, and their cost was very accurate[ CITATION Ang13 \l 1033 ]

Air Conditioning in Residential Building 4INTRODUCTIONThis study is based on defining a good design plan for heating ventilation and air conditioning for domestic building. Heating, ventilation and air conditioning systems perform cooling and heating for the residents, commercial and industrial building. They may be responsible for the giving the fresh air from outside to dilute the interior contaminants like volatile organic compounds and odours emitted from the furnishing and chemicals used for the cleanings[ CITATION MAn17 \l 1033 ]. Air is cooled and dehumidified by the conditioner as it passes over the cold coil’s surface. The coil inside the houses in heat exchanger of air to liquid with the tube rows where the liquid passes Fined connected surfaces to the tubes increases the coil surface‘s area hence increasing the characteristics of heat transfer the air passing over the coil and also liquid passing through thecoil and the type of liquid used to depend on the selected system[ CITATION Sha15 \l 1033 ].Through the innovative evaluation of new efficiency of energy for construction packages in Texas, BSC seek to get more evidence about the performance of technologies of energy efficient designed for the production builder in the climate of hot humid. This research addresses many barriers and gaps. The technology package proposed for this project is appropriate for the production of family detached houses. From the perspective of the science building, the Houston package is good for other products in the environments of humid hot. The information gotten through the research about the technology package implementation at the scale of the productive community at low-performance data from the houses of the community will support the deployment of the package in new housing across the climatic zones of hot humid[ CITATION Bma11 \l 1033 ].
Air Conditioning in Residential Building 5The immediate impact of the research will be to inform the work of David Weekley homes. Lessons gotten in economic variation in contractability and design can be applied to businesses mode; in the future production of buildings. The adoption of stringent international codes of energy conservation is reducing the performance gap between code built home and ones constructed to meet the standard of energy efficiency. The component of IECC is the mandatory inclusion of the system of heating ventilation and air conditioning and this mandate is making constructors to establish strategies of cost-effective for the ductwork movement to the thermal enclosure[ CITATION Mic16 \l 1033 ]. The project also can impact BA measures on improving the designs' replicability and cost-effectiveness that meet both the current code of energy and also in future improvement of the proposed building codes. This gives an opportunity for considering the importance of the method of duct location inside the conditioned space for production home builders to remain competitive in their markets. The paper gives the constructions and design data for production builder in the climate of hot humid[ CITATION Lin14 \l 1033 ].Background of studyThe study is based on the identification of the best strategies of design for implementation of air conditioning to suit the needs of cooling of the residential building. The passive strategies of cooling gains control over dissipation of heat are taken as good for the consistent climatic area while in modern houses, temperature changing is the major problem faced by the occupants. The unsuitable design cause heat to be trapped that increases temperature inside the room. The area of the roof that surrounds the building walls is known as a critical part because it is exposed to heat caused by high radiation of solar. The determination of this design strategies will reduce consumption of energy and provides comfort to the tenants of the building. This research has been undertaken to determine the best strategy design for conditioning air in the building so the
Air Conditioning in Residential Building 6requirement of the occupants in terms of comfort is fulfilled with respect to climate change[ CITATION Lin14 \l 1033 ].Statement of the problemThe occupants of houses are facing problems caused by changes in temperature, the unsuitable design cause heat to trapped by an increase in temperatures inside the rooms.to prevent all the problems it suitable to design a heating, ventilation and air conditioning systems in the conditioned rooms[ CITATION MBe14 \l 1033 ].Motivation for the researcherThe developing countries majorly that are located in dry climate regions experience the problem of heat retention by the building if ventilation is not enough for cooling at night. The residential building is designed without considering factors that are responsible for the thermal comfort and efficient use of energy, hence the dependence on the artificial lighting and ventilation is prevalent every residential building. Frequent power disruption and load shedding during summer make the life occupants more troublesome more so in hot summers between mid-marches and May[ CITATION Cor14 \l 1033 ]. Research questionsThe aim of the research is to study the air conditioning design strategy for the residential building to reduce the challenges faced by residents in the changing climatic zones. Some of the research questions that are prepared to perfume this study in details follow:Does the existing heating, ventilation and air conditioning systems or other cooling systems have the ability to match the requirements of cooling of the occupant’s houses?Does the strategy design being adopted by the building is good in terms of energy consumptions?
Air Conditioning in Residential Building 7What are the benefits of determining efficient air conditioning strategy for residential building?What is the best performing, most cost-effective and most method that is easily applicable of locating ducts inside the space conditioned for the home in the hot humid conditions?What is the practical and cost-effective method of achieving the source of energy savinResearch objectivesThe implementation of the proper strategy of design for air conditioning in residential building isthe essential element to fulfil the requirement of the occupants. The building strategy is continuously situated in changing the climate that needs proper strategy for installation of air conditioning[ CITATION Mag15 \l 1033 ]. The objectives prepared for performing the research include:To determine the capabilities of existing heating ventilation and air conditioning systems or other systems of cooling for matching the occupant's requirement of a residential buildingTo identify whether the strategy is suitable for the residential building in terms of consumption of energy’To evaluate the benefits of determining suitable strategies of air conditioning for residential buildingPreliminary or primary designThe strategies that exist for duct location in the conditioned space. The figure below shows the design 1 strategy where the air handling unit is located in the mechanical closet in the living space and the ductwork is located in the series of dropped ceiling placed strategically. The benefit of the design is to remain roof space becomes the traditional insulation and the typical vented can be installed. The barrier of air bec0ke the two-dimensional plane with the penetration of duct which is the simplified geometry of air barrier and it's economical. Negative impacts of the strategy are: conditioned area of the floor lost because of mechanical cost, lower ceiling level
Air Conditioning in Residential Building 8that reduced the architectural aesthetics, and potential noise from the mechanical closet[ CITATIONGer12 \l 1033 ].Risks of air handling unit closet noise can be prevented by implementing measures like: installing the speed variable of air handling unit with motor commutated electronically as the motors are quieter than permanent traditional split motor capacitors; installing at the mechanical closet a weather-stripped door; designing the duct system to perfume low velocities in return andsupply plenums recommended by Building Science Corporation[ CITATION Vau13 \l 1033 ]. Another strategy is where the air handler is in mechanical closet and the ductwork is in the attic close to ceiling plane. Traditional insulation is installed and the ductwork is covered in insulation. Its advantage is that it doesn't require the dropped ceiling through its disadvantages are conditioned area of floor lost because of mechanical close and penetration of duct exist through the barrier of air which needs more air sealing[ CITATION Mik16 \l 1033 ]The third strategy is where the air handling unit is placed in an air sealed coffered insulated closet in the attic and the ductwork is in dropped ceiling placed strategically. Its advantages are: no penetration of duct through the barrier of air and also the removal of air handling unit from the conditioned space is possible. Its disadvantages are: more complexity is added for air barrier and extraction is three dimensional and access to space coffer is the need and may not be easy with complicated attic design[ CITATION Bil13 \l 1033 ]The fourth design is where the air handling unit and all work duct are located in air coffered insulated closet in the attic. Importance of the of the strategy is the removal of the air handling unit from the living space conditioned and elimination of duct penetration through the air barrier and also dropped ceiling elimination[ CITATION Mik161 \l 1033 ]. The last strategy is where the air
