Learn about the different elements and details of various mechanical schedules, such as split system fan coil units and condensing unit schedules, energy recovery unit schedules, and ductless split system schedules. Gain insights into the markings, orientations, supply airflows, cooling capacities, and heating capacities of these units, among other things.
Key Insights
- The article provides a detailed overview of the various components of mechanical schedules, such as the tags, the areas served, the orientation, supply airflow, cooling capacity, heating capacity, and the basis of design which are often based on specific models from manufacturers like Trane and Aeon.
- It also explores the specifics of different schedules like energy recovery unit schedules, fan coil unit condensing schedules, and outside air schedules. Information about individual components, such as the heat wheel, cooling coil, airflow, horsepower, drive types, and design basis, are also discussed in-depth.
- The article further illustrates how to interpret the symbols used in these schedules, enhancing readers' understanding and ability to analyze mechanical schedules effectively.
Note: These materials offer prospective students a preview of how our classes are structured. Students enrolled in this course will receive access to the full set of materials, including video lectures, project-based assignments, and instructor feedback.
Let's look at our mechanical schedules. You can see a chart here for the split system fan coil units and condensing unit schedules. Here are all the marks or tags that we've seen throughout the drawings, the areas or rooms that are served, its orientation (you can see that these are vertically oriented), the supply airflow in cubic feet per minute for a fan, the cooling capacity, heating capacity, and the basis of design, meaning that these calculations are based on specific models manufactured by Trane.
Energy recovery unit (ERU) schedule, which part of the building it serves, the airflow CFM, exhaust fan airflow CFM, information about the heat wheel, the cooling coil, heat wheel input and output, and again, the basis of design, which is based on models manufactured by Aeon. And then here are some notes. Fan schedules: what the mark is, where they serve, whether they are inline, up-blast, makeup air, or roof exhaust, airflow, the ESP, horsepower, what kind of drive it uses, and there are some pertinent notes such as 1467 goes with the EF01, and the note listing is down here.
The ductless split system fan coil unit condensing schedules: their marks, where they are, and what type they are, whether they are wall-mounted or ceiling cassettes, airflow information, EER, basis of design, which is based off of a Mitsubishi, a chart for the packaged terminal air conditioner schedules, and you can see there is no entry for the electric heat schedule. Here's the outside air schedule: the appropriate room number, room name, square footage, number of people per thousand square feet, and calculations of the number of people, actual number of people served, the CFM per person, the CFM, and the effectiveness, and the outside air CFM. Finally, we have the diffuser, register, and grill schedule.
