This document serves as the comprehensive report for the testing and building for the Portable Water-Cooling System by team AquaCool. Team AquaCool is comprised of four mechanical engineers with a passion to help the agricultural industry in their efforts to keep the health of the workers at their peak. The four engineers who partook in helping the farm workers are as follows: Caleb F. Parham, Erik Torres, Gustavo Hernandez-Lerena, and Terry Leung. To reduce the risk of heatstroke and other unwanted effects from the harsh working conditions during summer, a small and portable system was built to help in the …

As housing prices and environmental concerns continue to increase, many people are looking for cheaper and more sustainable ways to live. A solution to both problems is building homes with smaller footprints which incorporate renewable energy and water-reclamation systems. In addition, adding a roof pond system to the dwelling also reduces the need for heating and cooling. The roof pond system uses a water bladder on the roof which acts as a heat-sink and moveable insulation panels. This document contains the process for our final design along with results from testing the verification prototype.

Mechanical Engineering
For this project, the goal was to conceptualize, design, test, and implement an active HVAC system to be used in the Solar Cal Poly house competing in the Department of Energy’s 2015 Solar Decathlon. With many house iterations, it was decided to use a split system with an outdoor heat pump and indoor air handler, paired with a HRV for ventilation. Through system modeling using Design Builder and Energy Pro 6.5, the cooling load of the house was determined along with the cooling schedule. The foreseen safety precautions and limited construction time guided the entire project, along with the active …

Net Zero Residential Design For Solar Calpoly, Bryce Reiko Willis
Master's Theses
The Department of Energy (DOE) confirmed Team Solar Cal Poly from California Polytechnic State University, San Luis Obispo, as a competitor in the 2015 Solar Decathlon in February 2014. The Solar Decathlon is a biennial collegiate competition to construct a net-zero home and operate it for a week of “normal use”. Solar Cal Poly needed assistance with passive and active HVAC systems for the design, and thermal load models. The competition will take place in Irvine, CA [33.67⁰, 117.82⁰ W] from September 27 – October 3, 2015. After the completion, a potential final location for the house will be Santa …

The Cal Poly Heating Ventilation and Air Conditioning (HVAC) Department was donated a fume hood so that it could be used for educational purposes in the lab. The fume hood was not fully set up and only ran in a constant volume mode; the fan ran at full speed with no feedback to reduce air flow. A fume hood can be opened or closed using the sash; air flowing through the sash opening must always be above a certain speed. As the sash is closed the opening grows smaller and the speed of the air increases. Two additional modes of …

The purpose of this document is to demonstrate the design, production, and testing of optimum pump sequencing logic for variable frequency drive (VFD) pumps in commercial heating ventilating and air conditioning (HVAC) systems. The product will be developed by Pump Efficiency Solutions (PES), which is a group of Cal Poly students working on their senior project. The product is being developed for Trane, an industry leader in large scale HVAC systems. MATLAB™, Microsoft Excel, Pump System Improvement Modeling Tool™ (PSIM), and fluid mechanics hand calculations were used during software development. Next, we converted the program into Trane’s graphical programming language …
