The document discusses cooling and heating load calculation. It lists the components of total cooling load for air conditioning such as building structure, internal loads, people load, air change load, and supplementary load. A safety factor of 5-10% is usually added to the total cooling load to account for inaccuracies. The meaning of plant capacity is explained as the capacity required to meet the total calculated cooling load while running the refrigeration or air conditioning system continuously for 24 hours. Procedures for calculating the cooling and heating loads and refrigeration plant capacity are also described.
Compressed Air Energy Storage at the North Campus of Durham College and the ...Matthew Crummey
The document is a capstone report that analyzes pairing a previously designed compressed air energy storage (CAES) system with the north campus of Durham College and the University of Ontario Institute of Technology. Historical electricity usage data from 2013-2014 was used with the CAES Simulink model to analyze the impact. Some design challenges in the original Simulink model were identified and addressed. Pairing the improved model with the historical demand data showed that operating the CAES system during specific times each day could save $157K in electricity costs for the 2013-2014 period.

The document discusses heat gain through building structures via conduction. It describes how heat is transferred through exterior walls, roofs, windows, and doors due to temperature differences. It explains that the solar radiation absorbed by outside surfaces of walls and roofs increases their temperature above the outside air temperature, which is known as the solar air temperature. The heat gain through walls and roofs can be calculated using the CLTD method, which factors in the surface area, overall U-value, and CLTD value from tables based on location and time of day. Infiltration through doors and windows also contributes to heat gain as outside air flows into the building.

This document presents an optimization of an air receiver tank for a reciprocating air compressor using sequential linear programming (SLP) and fuzzy sequential linear programming (FSLP). Stress analysis is conducted using theoretical calculations, experiments, and finite element analysis to compare stress values on different parts of the tank. An objective function is formulated to minimize tank volume, subject to constraints on maximum allowable stresses. A fuzzy logic controller is developed to modify the SLP algorithm by adjusting move limits and constraint boundaries based on constraint feasibility. The fuzzy-based approach is found to be easier to execute than conventional SLP.
Pressure Vessel Optimization a Fuzzy ApproachIJERA Editor
Optimization has become a significant area of development, both in research and for practicing design engineers. In this work here for optimization of air receiver tank, of reciprocating air compressor, the sequential linear programming method is being used. The capacity of tank is considered as optimization constraint. Conventional dimension of the tank are utilized as reference for defining range. Inequality constraints such as different design stresses for different parts of tank are determined and suitable values are selected. Algorithm is prepared and conventional SLP is done in MATLAB Software with C++ interface toget optimized dimension of tank. The conventional SLP is modified by introducing fuzzy heuristics and the relevant algorithm is prepared. Fuzzy based sequential linear programming is prepared and executed in MATLAB Software using fuzzy toolbox and optimization tool box and corresponding dimension are obtained. After comparison FSLP with SLP it is observed that FSLP is easier in execution.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
