Most buildings still rely on fossil energy --- such as oil, coal and natural gas for heating. This is because they are readily available have higher heat value than their cleaner counterparts. However, these primary sources of also high pollutants. As the grid moves towards eliminating CO 2 emission, replacing with alternatives imperative. Electric pumps an alternative heating technology been p...

The author has developed an engineering calculator for calculating the heat flow heating buildings according to enlarged parameters of object. algorithm is based on method determining amount energy and carrier in water systems municipal supply. carried out a systematic analysis thermal loads Russia data implemented building projects. With this mind, new coefficients a, n were calculated determi...

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...

Current developments of the European energy markets are influencing the operation strategy of heat suppliers. Especially providers of district heating systems fed by conventional heat production (i.e. CHP) have to react with appropriate measures to these changes. The integration of thermal storages, decentralization of the heat production, changing heating technologies or adjusting the temperat...

This work demonstrates the use of thin film heaters to enhance electrothermal pumping in microfluidic systems. Thin film heating electrothermal pumping is more efficient than Joule heating alone. Numerical simulations of an asymmetric electrode array are performed to demonstrate the advantages of incorporating thin film heaters. This specific simulation shows that thin film heater electrotherma...
