Thermal Comfort Conditions and Energy Efficiency of Buildings ab 59 EURO Thermal Adaptation Building Code Variable Thermostat of air conditioner
This book presents a proposed idea to make use of the thermal energy rejected by the condenser in a window-type or split air conditioning systems to decrease the air relative humidity of the cold air supplied by the air conditioner to a space for certain purposes. An amount of heat is rejected from the air conditioner through the condenser into its surrounding as a part of the refrigeration cycle. In this book, this lost energy is reused to heat water. Then the hot water is used to relatively decrease the relative humidity of the supplied-cooled air. Four variables were studied to find out the effective controlling parameters. These are the coil type (single or double), the amount of flowing water, water temperature, and the cold air velocity. The experimental results leads to the effective parameters that may improve the design of the introduced heat exchanger that make use of the heat rejected from the condenser. Finally, the proposed heat recovery concept in air conditioning systems can be worthy adopted and could achieve economic results in large scale systems.
This paper provides an overview of the Mexican electricity sector to frame the context in which energy efficiency national policies and strategies are developed. The paper then focuses on a specific energy efficiency strategy: residential air conditioner (AC) replacement programs. A spreadsheet model is presented as the core tool for analyzing three relevant air conditioner substitution programs in Mexico (FIPATERM ASI, FIDE PFAEE 2002-2006, and PNSEE). It then, provides a sensitivity analysis and scenario analysis for the PNSEE replacement program to provide insight on the main variables affecting the results of the program. The model estimates energy savings, CO2 emissions avoided and the economic impact to the user and to the utility. The FIPATERM and FIDE PFAEE 2002-2006 programs are estimated to result in 2,371 GWh saved and 1.4 million tons of CO2 avoided. Projected results from the PNSEE program are 4,710 GWh saved and 2.8 million tons of CO2 reduced by 2021. Improvements to the program rules, better information of AC stock, and improved reporting transparency, are some of the final recommendations for enhancing the benefits of air conditioner replacement programs.
Heat is always been a problem in every country such as India and Asian country. Now a day's energy is major requirement to reduce energy crisis. So ours Project is an effort towards this direction. When doing work or event, the place could become stuffy and uncomfortable for technician or engineer. However, air conditioners are mostly marketed as fix and hard to change places portable air conditioners are dime a dozen but somehow are very expensive to have. In this project, we aim to make a portable air conditioner that is affordable and reliably cool small confined for a limited amount of time and space. It has microwave sensor which detect the human body temperature. If temperature is greater than atmospheric temperature then it will start otherwise it will stop.
The designing of the solar panels at the top of the bus is calculated by three major steps, 1) The calculation is done for electrical energy demand of air conditioner in bus by using thermodynamic temperature flow inside the bus, with respect to the minimum and maximum temperature data for Chennai city during year 2008. 2) The calculation is done for monthly energy produced by single chosen solar panel using the solar radiation data for Chennai. 3) Internal Electrical circuit is designed for the bus by choosing the specific MPPT solar charge controller and battery for storage. All the calculation are done using MAT LAB.
