Canadian researchers are now trying to exploit much more energy from solar sources, hydropower, wind, and biomass. Given the fact that reducing the carbon pollutant level is a political priority in Canada, this paper studies the feasibility of providing sanitary hot water and space heating demands of a four-member family in 10 provinces in this country. The feasibility analysis was performed by...

abstract: mustard is a natural multi-functional additive with strong hot flavor. in this research, powdered yellow mustard (sinapis alba) was heated by 21 different thermal processes, statistically designed by response surface methodology to evaluate the effects of combinations of heating media (hot air, hot water and steam) and heating time (0-20 min) on residual myrosinase activity, the minim...

Hot air and hot water heating methods have been extensively studied as thermal treatments to control insect pests in fruits to replace chemical fumigation. An inherent difficulty in using these methods is that slow heating rates may result in long treatment times and possible damage to fruit quality. Many factors influence heating time. A systematic analysis of those influences is desirable to ...

A multi-functional heat-pump system is proposed to efficiently utilize the gray water as heat source and sink for heating and cooling of residential buildings, respectively. Heat is reclaimed from the plate heat exchanger installed at the outlet of the compressor to provide sufficient hot water for residential use. To study the performance of this innovative system, laboratory testing is perfor...

This paper reports a plenary thermodynamic model of a novel solar system for water heating in buildings. Energy and exergy analyses are used to characterize the exergy destruction rate in any component and calculate system overall efficiency. The system consists of a solar evaporator, a heat exchanger to produce hot water, and an auxiliary pump. A computer simulation program using EES software ...

With the urbanization process of the hot summer and cold winter (HSCW) zone in China, the energy consumption of space and water heating in urban residential buildings of the HSCW zone has increased rapidly. This study presents the energy efficiency and sustainability evaluation of various ways of space and water heating taking 10 typical cities in the HSCW zone as research cases. Two indicators...

This paper presents investigative results of the energy efficiency of hot water production for sanitary uses by means of gas-fired water heaters with the combustion chamber sealed with respect to the room in single-family houses and multi-story buildings. Additionally, calculations were made of the influence of pre-heating the air for combustion in the chimney and air supply system on the energ...

In this paper solar assisted heating and absorption cooling system and domestic hot water needs for a hotel having fifty rooms in Antalya have been investigated. First of all, solar radiation and meteorological data for Antalya and heating and cooling loads of the hotel building are given. For the heating cycle, active systems using liquid as the working fluid; and for the cooling cycle, solar-...

The prevention and control of legionellosis in water supply systems involves environmental comprehensive sampling. Our aim was to investigate occurrence of Legionella spp. in water supply systems in different administrative districts of Riga, and to find out if there exists a correlation between Legionella spp. positive cases and water source, type of sample, sampling point and temperature of h...
