An air-conditioning system utilizing solar energy would generally be more efficient, cost wise, if it was used to provide both heating and cooling requirements in the building it serves. Various solar powered heating systems have been tested extensively, but solar powered air conditioning systems have received very little attention. Solar powered absorption cooling systems can serve both heating and cooling requirements in the building it serves. Many researchers have studied the solar absorption air conditioning system in order to make it economically and technically viable. But still, much more research in this area is needed. This paper will help many researchers working in this area and provide them with fundamental knowledge on absorption systems, and a detailed review on the past efforts in the field of solar absorption cooling systems with the absorption pair of lithium-bromide and water. This knowledge will help them to start the parametric study in order to investigate the influence of key parameters on the overall system performance.

This paper reports the performance of a lithium bromide absorption chiller in a solar powered air conditioning system, when being operated conventionally. The chiller performance based on a modified solar powered absorption air conditioning system which is integrated with a partitioned storage tank has been presented and discussed. It is shown that, by partitioning the storage tank, the chiller performance is not significantly affected, and the solar powered cooling effect can be realized much earlier, achieving a higher total solar cooling COPsystem, compared to the conventional system designs.

Among the broad varieties of power supply in Afghanistan such as city power produced from water dams, fuel generators, and imported electricity from neighboring countries, solar energy production is growing at a noticeable pace. Its preference is because of cost and sustainability perimeters. Given the climate of the country air conditioning inside buildings is required throughout the year, which is an important requirement for the comfort of its residents. Because it requires a great amount of energy, therefore, most companies are working on different principles to provide new products of solar air conditioning systems. The solar air conditioning system provides heating and cooling by utilizing solar energy. Recently, climate change and air pollution proved to be a major challenge for humans, and the current rate of resource consumption will result in a total depletion of natural energy resources in the earth. In this paper, we are assessing the feasibility study of solar-powered air conditioner technology in Afghanistan. Considering the weather of the country, there exists enormous potential for solar energy production. Afghanistan receives 4 – 6.5 kWh/m2 /day solar insolation on average with 300 sunny days a year. In conclusion, the air conditioning complication which can be addressed by solar energy production is sustainable, cost-effective, and environment-friendly manner in Afghanistan.

Effective Life

Phase-change through condensation and evaporation processes takes place in many daily-use heating and cooling systems. However, if these processes experience uncontrolled pressure and temperature conditions, shock waves may be generated. Depending on the strength and conditions of the generated waves, they can decrease the effective life of equipment or even cause devastating destruction. Cavitation and water hammer phenomena are examples of flow issues that are well understood and reported in thermal/fluid systems, although not many studies have been published in open literature on condensation-induced shock (CIS) with the applications in refrigeration and air conditioning systems. This study reviews the limited literature on this topic, analyze the complex CIS phenomenon, derives and solves the governing equations, presents the results of typical conditions that may happen in different residential and industrial applications, and provides ways to avoid devastating incidents that may occur as a result of this phenomena.

Solar Absorption Cooling

As one of the most promising solutions to the reduction of fossil fuel consumption and greenhouse gas emissions, the use of solar energy for building space heating and cooling recently has again aroused researcher’s interest with the growing awareness of the global warming and other environmental problems. Compared to the relatively mature solar heating, solar cooling technology remains at the demonstration and testing stage due to its complicated system characteristics, both in concept and construction. Among many solar cooling technologies, solar absorption technology is the most suitable technology for the solar cooling. The major barriers to widespread deployment of the solar absorption cooling are its high first cost, the lack of guidelines of its design and operation, and the relative low system performance due to the lack of the system integration. The paper provides detailed information of an on-going solar heating and cooling research project conducted at Purdue University in West Lafayette, Indiana. The aim of the research is to develop a cost-effective and integrated solar heating and cooling system. The solar thermal system primarily includes a 45kW single effect absorption chiller, evacuated tube solar collectors (ET), and heat storage tanks. The system has been designed based upon scientific principles and engineering fundamentals. It has been analyzed and optimized to achieve the high cost-effectiveness and the high system efficiency through the system performance simulation in Transient Energy System Simulation (TRNSYS) program.

<p>Air conditioning (AC) is one of the most building’s energy consumer, included in building of Engineering Physisc’s Departement, Universitas Gadjah Mada (UGM). The declining of fossil fuel reserves and the increasing effects of global warming, forcing the world to switch to renewable energy sources. This paper discusses the design of solar absorption cooling system to replace conventional AC in seven lecture halls of Engineering Physic’s Departement, UGM. There are some steps that have been done to design the solar absorption cooling, i.e. do a study of the potential availability of solar energy, calculate the cooling loads, analyze the thermodynamic process of the system, determine the type of collector to be used and calculate area of solar collector needed. The thermal coefficient of performance (COP) of the system designed was about 0.84 which could use some types of flat plate solar collector with each area corresponding to each efficiency values. </p><p><strong>Keyword</strong> : Air conditioning; global warming; solar absorption cooling; solar collector</p>

Air Conditioning Systems

Centralized air conditioning systems are widely used in buildings at present. In these conditioners, the outside air gets required temperature, humidity, purity, and other features, necessary for creating comfort microclimate in inside areas of houses, and by the help of fans and air ducts the processed air moves to all rooms of a building. As a result, the creation and maintenance of comfort conditions in buildings become complicated and expensive activity. From this point of view, it is becoming more expedient to install local air conditioners in each room instead of single central one for the whole building. For this reason new local air conditioner is developed.
