Book Description
Cooling of buildings using a solar energy absorption system is studied analytically. Simulation is done for a three TR absorption-air conditioning system to supply cooling to a proposed 100 square meter house under Beirut's weather conditions The thermal performance of forced circulation flat plate solar collectors is simulated numerically using DufTie and Beckman model with a fully mixed storage tank [1,2]. The absorption system generator is simulated so as to calculate the required load from the solar system. Thermodynamic properties of the cooling absorption system are calculated in the program at different points of the system cycle, and the absorption system's performance is predicted for different operating conditions including generator load and condenser temperature. For the cooling load; good results are attained. For collector area of 80.4 About six hours of solar energy-dependent cooling per day is reached during the five months: May, June, July, August, and September. In addition, domestic hot water was supplied from the tank for domestic use. The yearly solar fraction for these months these months ranged in the neighborhood of 20%. This analysis is performed by using the design days for the summer months as suggested by Beckman [2] and assuming that system does not have extra storage of thermal energy for night use. Finally the cost analysis showed that the pay back period of the system is between 14-15 years compared to conventional vapor compression system.

Book Description
HEATING, VENTILATING, AND AIR CONDITIONING Completely revised with the latest HVAC design practices! Based on the most recent standards from ASHRAE, this Sixth Edition provides complete and up-to-date coverage of all aspects of heating, ventilation, and air conditioning. You’ll find the latest load calculation procedures, indoor air quality procedures, and issues related to ozone depletion. Throughout the text, numerous worked examples clearly show you how to apply the concepts in realistic scenarios. In addition, several computer programs (several new to this edition) help you understand key concepts and allow you to simulate various scenarios, such as psychometrics and air quality, load calculations, piping system design, duct system design, and cooling coil simulation. Additionally, the load calculation program has been revised and updated. These computer programs are available at the book’s website: www.wiley.com/college/mcquiston Key Features of the Sixth Edition Additional new worked examples in the text and on the accompanying software. Chapters 6-9 have been extensively revised for clarity and ease of use. Chapter 8, The Cooling Load, now includes two approaches: the heat balance method, as recommended by ASHRAE, and the simpler RTS method. Both approaches include computer applications to aid in calculations. Provides complete, authoritative treatment of all aspects of HVAC, based on current ASHRAE standards. Numerous worked examples and homework problems provide realistic scenarios to apply concepts.
