HVAC 3013 Bonus Assignment worth extra 15 marks if correct. Provide a Word document with the following information. Please note: You must do your own assignment. I will not accept duplicate word documents. Any duplicate or significantly similar documents will not be accepted. When selecting a furnace and cooling equipment, always start with the first furnace and coil that meets the minimum loss and gain. Make sure the equipment you select can handle the maximum air flow rates. House Heat Loss – 64,833 btuh House Heat gain – 29,597 btuh Furnace Model, Output, Temp. Rise range, Actual heating CFM. Condenser model, Output Evaporator model, Coil Pressure drop, Actual cooling CFM. System Design CFM, System Design Pressure, System Available pressure. Selected filter drop Pressure. Cooling Air Flow Factor and Heating air flow Factor. HVAC 3013 Bonus Assignment worth extra 15 marks if correct. (Part marks will be given) Using the following heat loss and heat gain; 1) Determine the furnace model and heating cfm. 2) Specify Furnace output. 3) Determine the Condenser and evaporator models and sizes plus the cooling cfm. 4) Specify condsenser output. 5) Determine the design CFM. 6) Determine the system design External Static Pressure. 7) Determine the Available design static pressure. 8) Complete the attached word document with your answers. You can use the equipment selection section of the residential excel heat loss/duct design spreadsheet. 9) Selection from the HVAC equipment attached. HVAC 3016 Bonus assignment (15 Marks total. Part marks given) Scenario: You are required to design the ventilation system for a 3 level underground parking garage. Each level is 200ft x 165 ft x 7ft high. The client requires that the ventilation system provide 2 air changes per hour (ACH) when the Carbon Monoxide detection systems detect an elevated level of CO and brings on the ventilation system. You will be required to specify a Greenheck Wall Mounted Exhaust fan and a motorized damper (also Greenheck) capable of the 2 ACH. Other specifications for the fan are; Static Pressure - .5 Elevation – 20ft Air Stream Temperature – 60 f Voltage – 208/60/3 You are to choose the fan with the lowest “Sone” rating. If two of more fans have the same sone rating, choose the fan with the lowest BHP. Specifications for the “Control Damper” must be “Aerofoil” blade type, Maximum Velocity 4000 fpm and must be capable of operating between -40⁰f to 250⁰f. Choose a SQUARE Damper size at 750fpm velocity. You will use the website, www.greenheck.com You will select “Greenheck l Building Value in Air” You will select “Resources” Under the “Resources” tab on the left of the screen you will select “Software” Under “Software”, you will click on “eCaps” On the eCaps page, scroll down and click “open eCaps” Locate the “Wall Mounted” fans button and click it. Input your selection criteria from above and select the fan from the search results provided. For the “Control Damper”, return back to the eCaps main page and under toolbox, click “Damper selection guide”. Locate the “Control Dampers” button and click on it. Review the different dampers listed to locate a Control Damper matching the above requirements. Go to “Honeyweel.com” and choose an appropriate “Actuator”. Ensure the actuator is “Normally Open”. Please note that for Carbon Monoxide detection systems, all dampers providing fresh air shall be “Normally Open” during a power failure. Your Word or Excel document report will be in the form of an Equipment Schedule. Include the make, model and all specific specifications for the fan, control damper and Actuator. You should be as detailed as possible. You can include a “Notes” section below the Equipment Schedule if you think there is any important information that should be included such as specific installation requirements or design criteria.
