Traditional fossil fuels lead to environmental problems and are also depleting. A significant portion of global energy consumption is due to building’s air conditioning. Nowadays there is a great attention toward renewable and sustainable energy sources to support the buildings energy requirements. In this study, a solar cooling machine was designed for a three-floor residential building under ...
abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
AirConditioning Engineers (ASHRAE RP-1462). It is a three years' research, including the literature review, labs construction, experiments and data analysis. In this thesis, first of all, we conducted literature review of mechanism motion influence on heat and mass transfer and additive effect in absorption chiller. This part helps us understand the basic idea of how mechanism motion affects th...
In this research, the thermodynamic investigation of the tri-generation system is performed by the first and second law of Thermodynamics. The trigeneration system under study consists of three subsystems including the solar subsystem, Kalina subsystem and lithium bromide-water absorption chiller subsystem. The proposed system generates power, cooling and hot water using solar energy. The syste...
One of the important energy consuming sectors of the country is buildings. In this research, we use the energy audit of the Atisaz complex in Tehran to evaluate the economic benefits of energy saving measures. We evaluate measures such as: using the automatic damper, replacing the active existing chiller with the solar absorption one, using intelligent boiler-room and replacing the existing li...
Absorption chillers present opportunities to utilize sustainable fuels in the production of chilled water. An assessment of the steam driven absorption chiller at the University of Idaho, was performed to quantify the current exergy destruction rates. Measurements of external processes and flows were used to create a mathematical model. Using engineering equation solver to analyze and identify ...
In this article a CCHP system has been proposed for recovering waste heat of PEM fuel cell and this system can be used for residential applications. Main components of the system are PEM fuel cell, absorption chiller, fuel processor and heat storage tank. Electrochemical equations of PEM have been modeled by MATLAB and the chiller, fuel processor and boiler have been modeled by EES. In addition...
Energy needs of air conditioning systems are constantly growing worldwide, due to climate change and standards buildings. Among the possible systems, solar heating cooling based on reversible heat pumps thermally driven chillers a viable option for ensuring space different users. The high installation costs limit their diffusion, however, under specific circumstances (climate, type building, us...
This paper proposes the first application of a split-range control technique on concentrating solar collector to improve an absorption plant production. Solar plants have power availability in phase with cooling demand under design conditions. Thus, it is powerful technology context renewable energy and efficiency. These need systems cope irradiance intermittency, reject irradiation disturbance...
