چکیده
In the design and operation of cold storage systems, the problems of saving operation cost and improving global economics of whole systems are equally important. Based on optimal control, yearly dynamic cooling loads and payback period, a method to design an optimal scheme is proposed. An approach to calculate and choose the chiller and cold storage tank for the optimal scheme is provided in the method. The optimal scheme not only minimizes operating cost, but also is the most economical among all the cold storage systems with common control strategies. The method is demonstrated by a case study, in which the optimal scheme is compared on economics with other schemes with chiller priority control or storage priority control. It can be seen that the payback period of the optimal scheme is the shortest. 2002 Elsevier Science Ltd. All rights reserved.

Direct injection of liquid CO2 into the ocean has been proposed as one method to reduce the emission levels of CO2 into the atmosphere. When liquid CO2 is injected (normally as droplets) at ocean depths >500 m, a solid interfacial region between the CO2 and the water is observed to form. This region consists of hydrate clathrates and hinders the rate of dissolution of CO2. It is, therefore, exp...

In face of the likely doubling of the world population and perhaps tripling of the power demand over the next 50 years, this paper (1) presents some thoughts on the possible ways to meet the power demands under the constraints of increased population and land use while holding the environmental impact to a tolerable one, and (2) outlines the ways exergy analysis may be effectively used in the c...

Two wet biomass gasification processes, supercritical water gasification and biomethanation, were evaluated from energy, environmental, and economic aspects. Gasification of 1 dry-t/d of water hyacinth was taken as a model case. Assumptions were made that system should be energetically independent, that no environmentally harmful material should be released, and that carbon dioxide should be re...

Support Vector Machines (SVMs) which is one kind of learning machines, was applied to predict the specificity of GalNAc-transferase. The examination for the self-consistency and the jackknife test of the SVMs method were tested for the training dataset (305 oligopeptides), the correct rate of self-consistency and jackknife test reaches 100% and 84.9%, respectively. Furthermore, the prediction o...

Adsorption cold storage has lately attracted attention for its large storage capacity and zero cold energy loss during the storing process. Thermodynamic and experimental studies on the cold storage capacity and the cold discharging process, in which the adsorber is either air cooled or adiabatic, have been presented. An adsorption cold storage system with zeolite–water working pair has been de...
