Evaluating the potential of modular passive cooling systems

An Improved Modular Modeling for Analysis of Closed-Cycle Absorption Cooling Systems

A detailed modular modeling of an absorbent cooling system is presented in this paper. The model including the key components is described in terms of design parameters, inputs, control variables, and outputs. The model is used to simulate the operating conditions for estimating the behavior of individual components and system performance, and to conduct a sensitivity analysis based on the give...

Passive Energy Air-to-Water Heat Pipe Based Heat Exchanger and its Potential of Air Pre-cooling in Air Conditioning Systems for Iran Climate

Air pre-cooling equipment is normally being employed in air-conditioning systems for pre-cooling the ambient outdoor air to enhance the air-conditioning systems performance. In this study, the potential of a passive water-to-air heat pipe based heat exchanger (HPHEX) for air pre-cooling purpose in air-conditioning systems for the high cooling load demanding regions of Iran was investigated. To ...

Modelling Buoyancy Induced Flows of Passive Cooling Systems

The main objective of this study is to develop and validate a systematic methodology to model a system of buried pipes, assisted by a solar chimney to promote the natural ventilation, in the whole building simulation software ESP-r (Clarke 2001), from a software user perspective. This development was supported by monitored data collected at an experimental site in Évora, Portugal. A multi-zone ...

A Proposed Model for Evaluating Modular Education

Introduction: Educational evaluation is one of the main elements of educational systems. It also has a particular role in different educational standards such as ISO 10015. It seems that oral and written examinations are not enough for an effective evaluation of instructions. In order to accomplish an efficient educational evaluation, an evaluation model was designed for educational assessment ...
