Cement production is an energy-intensive process, so that the cement industry occupies a top position among other energy-consuming industries. Among the equipment used in cement industries, boilers are one of the energy-consuming equipment. Boilers are among the common heating equipment in industrial, commercial, and institutional facilities. In this paper, the performance of thermal oil bo...

c Traditionally, single-zone VAV has been used for larger, densely occupied zones that have variable cooling loads. Common examples include gymnasiums, cafeterias, lecture halls, auditoriums, large meeting rooms, churches, and arenas. Therefore, it has been available primarily in larger airhandling units and large, packaged rooftop equipment. This type of equipment has long been available with ...

The type of heating, ventilation and air conditioning (HVAC) system has a large impact on the heating and cooling energy consumption in multifamily residential buildings. This paper compares the energy performance of three HVAC systems: a direct expansion (DX) split system, a split air source heat pump (ASHP) system, and a closedloop water source heat pump (WSHP) system with a boiler and an eva...

Many minerals are effective absorbers of microwave energy, whereas in general gangue materials are not. This suggests applying microwave heating to mineral processing to effect selective heating of minerai phases. Many mineral processing applications have been tested only on a laboratory scale; the engineering realities of large-scale operations have largely been overlooked. Of particular conce...

Polymer melts are highly-viscous non-Newtonian fluids. The manufacture of an article from polymer involves heating, shaping and cooling processes. The rheology of the polymer melt is considered to be one of the most important factors in determining the properties of a polymer product, the properties being related to the flow and deformation of the fluid particles in the processing equipment. Th...

As a kind of link terminal in power grid system, clamp has become one the key components and widely used for connecting transmission lines electrical equipment. However, joint between tubular structure plate or drainage is always weak part, which easy to produce defects then accelerate failure during service. This also limited use space certain extent. In this paper, research status on heating ...

This paper presents generic equipment models that capture the performance of families of similar heat pumps equipment and that can be used in building simulation programs. Mapping has been carried out for families of single and dual compressor speed ducted split systems and the correlations are being implemented as components for building simulation. The units mapped ranged in nominal capacity ...
