Compute the cooling load of a south-facing Pittsburgh wall using u value, cltd, and lm, with brick, insulation, and concrete, for interior 77 f and outside conditions.
Explore psychometrics as the science of the thermodynamic properties of moist air. Learn how the psychometric chart visualizes dew point, humidity ratio, and temperatures to analyze air quality and properties.
Learn psychometric properties in HVAC: dry bulb and wet bulb temperatures, enthalpy in BTU per pound of dry air, and relative humidity on the psychometric chart.
Explore how to read a psychometric chart to determine relative humidity, dry bulb temperature, specific volume, enthalpy, wet bulb temperature, and humidity ratio for HVAC design.
Apply psychometric analysis to select a cooling coil using fresh air CFM, defining dry-bulb temperature and relative humidity, and balancing latent and sensible energy to meet on-coil conditions.
Analyze evaporative cooling with psychrometric analysis, showing how adding water vapor lowers air temperature and yields fresh air through a spray-pump system, with cooling effectiveness around 91.5%.
Explain how room air distribution devices, or GRD (grills, registers, and diffusers), control temperature within ±2°F of the design temperature and maintain occupied-space air velocity between 25 and 70 fpm.
Explore the ducting system that transports air and gases through buildings, a key component of hvac and air distribution systems, ensuring efficient, controlled movement of air throughout spaces.
