Abstract With the fourth generation of district heating networks in sight, opportunities are rising for better services and optimized planning energy production. Indeed, more intensive data collection is expected to allow load prediction, customer profiling, etc. In this context, our work aims at a understanding profiles from captured data. Given variety households, such difficult capture. This...

The ORC technology in cogenerative systems has by now reached a level of full maturity in biomass applications. In Europe, there are over 120 plants in operation with sizes between 0.2 and 2.5 MW electric. ORC systems are very flexible and can be used in different applications like district heating systems, pellet production factories, sawmills and tri-generation systems with absorption chiller...

in this paper the changes in the heat capacity of cooling towers has been investigated as a result of injecting combustion products of boilers. in the tower, the air is re-heated through mixing with hot flue gas after passing through the heat exchangers. as a result of this process, the draft of the cooling tower is increased. the additional produced draft depends on the ambient temperature and...

In our daily life, central heating systems are generally used in home and office heating. The majority of fuel used in these systems are either natural gas or coal. However, in some cases air-conditioners and electrical oil-radiators are preferred in the heating of small mediums. But, the cost of electrical based heating is much higher than the cost of natural gas or coal based heating. Conside...

In this study, a complete evaluation procedure of energy-saving and efficiency improvement for a large-scale hospital retrofit project has been established and successfully validated in Taiwan. The retrofit scheme, in integrating the alternative hot water system, namely, a water source heat pump (WSHP), with the existing HVAC (Heating, Ventilating, and Air-Conditioning) system, enables the capa...

The hydrothermal synthesis of zeolites carried out in batch reactors takes a time so long (typically, on the order of days) that the crystallization of zeolites has long been believed to be very slow in nature. We herein present a synthetic process for ZSM-5, an industrially important zeolite, on the order of seconds in a continuous flow reactor using pressurized hot water as a heating medium. ...
