A Study of Heat Pump Fin Staged Evaporators Under Frosting Conditions
(Texas A&M University, 2004-09-30)
This dissertation provides a detailed description of the research work completed on fin staged heat
exchangers. The effects of staging fin on the frosting performance of heat pump evaporators and the
whole heat pump ...
An Investigation of Alternative Methods for Measuring Static Pressure of Unitary Air Conditioners and Heat Pumps
(2013-08-12)
This project was created to address an important issue currently faced by test facilities measuring static pressure for air-conditioning and heat pumps. Specifically, ASHRAE Standard 37, the industry standard for test ...
Range Hood Capture Efficiency Design Modeling
(2016-12-01)
This study assessed and modeled the performance of a range-hood ventilation system and the important aspects such as major and minor pressure losses, volumetric airflow, and capture efficiency. Results can be classified ...
Modeling of Electronically Commutated Motor Controlled Fan-powered Terminal Units
(2011-02-22)
Empirical models of airflow and power consumption were developed for series
and parallel variable air volume fan powered terminal units (FPTUs). An experimental
setup and test procedure were developed to test the terminal ...
Dynamic Monitoring and Displacement Ventilation to Prevent Pathogen Spread During Meat Processing
(2019-11-08)
Shiga toxin producing E. coli (STEC) and Salmonella are two prominent bacteria that are recognized in pathogenic spread in the meat industry. In recent years outbreaks have occurred due to the ingestion of contaminated ...
