Plug-In Hybrid Electric Vehicle Hvac Optimization, Jessica Hartl
Plug-In Hybrid Electric Vehicle Hvac Optimization, Jessica Hartl
Honors Theses
The objective of the proposed project is to convert the current heating ventilating and air conditioning system, or HVAC system, on the plug in hybrid Toyota Prius into a completely electric system. As the vehicle is now, the gas engine is required to provide heat loss for the forced air heating system on extremely cold days. The data, which has been gathered over several years, shows a drop in MPG equivalence from approximately 100-120 MPG on ideal days (70° F) to about 50 MPG equivalence on cooler days. This problem can be solved by increasing the effectiveness of the HVAC …
Investigation Of A Water Desalination Method Via A Humidification-Dehumidification Process Using Hvac Technology, Juan Antonio Cornejo
Investigation Of A Water Desalination Method Via A Humidification-Dehumidification Process Using Hvac Technology, Juan Antonio Cornejo
Open Access Theses & Dissertations
Potable water is becoming a scarce resource in many arid regions of the world. An experimental unit was designed and constructed to examine and characterize the production capabilities of a humidification-dehumidification (HDH) desalination process. An HDH cycle offers a viable, technologically light, alternative for producing fresh water from brackish water because the low relative humidity air is infused with water vapor through evaporation by means of conventional heating, ventilation and air conditioning (HVAC) components. The evaporation process effectively separates salts and suspended solids from the brackish feed-water. Desalinated water is subsequently recovered by extracting the water vapor from the moist …
Simulation And Experimental Validation Of Airborne And Structure-Borne Noise Transmission In Hvac Plenums, Srinivasan Ramalingam
Simulation And Experimental Validation Of Airborne And Structure-Borne Noise Transmission In Hvac Plenums, Srinivasan Ramalingam
Theses and Dissertations--Mechanical Engineering
This research demonstrates the usage of numerical acoustics to model sound and vibrational energy propagation in HVAC ducts and plenums. Noise and vibration in HVAC systems propagates along three primary paths that can be classified as airborne direct, airborne indirect and structure-borne. The airborne direct path was simulated using acoustic FEM with special boundary conditions to handle the diffuse acoustic field loading and the baffled termination. The insertion loss for a number of different plenum geometries was compared to published measurement results. Results were in good agreement both below and above the cutoff frequency. Additionally, the airborne indirect path, often …

A Voltage Flicker Suppression Device For Residential Air Conditioners And Heat Pumps, John Fox
A Voltage Flicker Suppression Device For Residential Air Conditioners And Heat Pumps, John Fox
All Theses
In some circumstances, voltage flicker due to the inrush current of residential heat pump can be a fairly visible to the residents as a slight flashing of the household's lights during the compressor starting event. The voltage flicker problem is caused by a variable contribution from sizable equivalent power system impedances and considerable inrush currents drawn by compressors. While this is not a new problem, and there are technologies on the market that attempt to alleviate the voltage flicker issue, no current solution attempts to correct for the problem at its root cause.
This thesis presents a device designed to …

Pump Sequencing Optimization, John S. Allan, Kyle J. Nekimken, Spencer B. Weills
Mechanical Engineering
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 …
