Development Of Simulation Modules For Liquid Desiccant Systems In Sorpsim, Zhiyao Yang

Open Access Theses

Liquid Desiccant Systems (LDS) have been an attractive alternative to the conventional vapor-compression air conditioning technology in HVAC applications for their thermally-driven nature and the expertise in dealing with large latent load in a more energy-efficient way. Much effort has been made during the past decades to study the performance of LDS and their components both experimentally and through modelling approach. However, predicting the performance of LDS is still a skill-demanding task because it involves model implementation, retrieval of fluid properties, solving procedure setup, and preparation of a good set of initial guess value to model just one component. It …

Environmental Monitoring In Preparation For The Installation Of A Green Roof, Andrew N. Martin, Ming Qu

The Summer Undergraduate Research Fellowship (SURF) Symposium

Green roofs are becoming an increasingly popular way to improve the environmental, economic, and aesthetic performance of both new and existing buildings. Along with the green roofs themselves, it is also common to install sensors to measure various environmental parameters that are affected by or important to the operation of the roof such as precipitation, temperature, and runoff. However, for most of these systems, the sensors are installed at the same time or even after the green roof. Therefore, no before-and-after comparisons can be made for those roofs. To account for this missing data, monitoring equipment was installed on a …

Assessing The Engineering Performance Of Affordable Net-Zero Energy Housing, Jordan P. Wallpe

Purdue Polytechnic Masters Theses

The purpose of this research was to evaluate affordable technologies that are capable of providing attractive, cost-effective energy savings to the housing industry. The research did so by investigating the 2011 Solar Decathlon competition, with additional insight from the Purdue INhome. Insight from the Purdue INhome verified the importance of using a three step design process to design a net-zero energy building. In addition, energy consumption values of the INhome were used to compare and contrast different systems used in other houses.

Evaluation of unbiased competition contests gave a better understanding of how a house can realistically reach net-zero. Upon …
