Aim of this project is the development of a new heat pump system with economizing that is able to improve the heating performance using two or more heat sources at different temperature levels. These heat sources are incorporated into the system with minimal loss of exergy by adding the heat at different pressure levels. Practical applications for such systems are for example buildings with a h...

Many companies in India manufacture solar water heaters but these are not becoming popular in the domestic sector because of their high cost. The Ministry of Non-Conventional Energy Sources (MNES), New Delhi is recommending flat-plate collectors with copper (Cu) risers, headers and plate. Therefore, their cost is high. Long term studies have been carried out at the Central Arid Zone Research In...

The objectives of this work are: (a) to present a new system for building heating which is based on underground energy storage, (b) develop mathematical model the system, and (c) optimise performance system. includes Photovoltaic Thermal Hybrid Solar Panels (PVT) panels with cooling, an evacuated solar collector water-to-water heat pump. Additionally, storage tanks, placed underground, are used...

In this paper, the experimental design and computer simulation model of a multi-effect humidification/dehumidification (MEH) solar desalination system has been presented. The pilot plant on MEH was designed, fabricated and tested at the Center for Energy Studies, Indian Institute of Technology Delhi, India. The heat collection part has been designed to provide continuously the hot water to the ...

Temperature is one of the most principle factors affects aquaculture system. It can cause stress and mortality or superior environment for growth and reproduction. This paper presents the control of pond water temperature using artificial intelligence technique. The water temperature is very important parameter for shrimp growth. The required temperature for optimal growth is 34C, if temperatur...

Domestic Hot Water (DHW) storage tanks are identified as a main source of flexible energy use in buildings. As basis for management apartment buildings, this paper describes the aggregated DHW case building, and analyses potential flexibility by simulating different control options. The study work is an building Oslo with 56 apartments shared system. Energy measurements available consumed hot w...
