Full Description This text provides an understanding of fundamental HVAC concepts and how to extend these principles to the explanation of simple design tools used to create building systems that are efficient and provide comfortable and healthy environments. The text contains twelve chapters that review the fundamentals of refrigeration, heat transfer, and psychrometrics. Other topics include equipment selection and specification, comfort and IAQ, building assemblies, heating and cooling loads, air distribution system design, water distribution system design, electrical and control systems, design for energy efficiency, and design for economic value. A suite of complementary spreadsheet programs that incorporate design and computation procedures from the text are provided on the CD that accompanies this book. These programs include psychrometric analysis, equipment selection, heating and cooling load calculation, an electronic "ductulator," piping system design, a ductwork cost calculator, and programs to evaluate building system demand and energy efficiency. Future updates to these programs can be found at ashrae.
Option 3 with very little cushion for extremely cold days. Assume a pump power requirement of W this replaces the outdoor fan of an air unit and indoor fan is included in the total kW. The fan must deliver 1. Select a rooftop unit to cool this zone. You must convert them to total net capacities by deducting the fan heat.
The required outdoor air ventilation rate is cfm. Specify the required cfm. Select a rooftop cooling unit from Table 5. Recall the capacities given are gross.
Loads Room: Use Model Input values Qair1 and Qair2 are in cubic feet per minute. A Model Table 5. Determine the head loss in feet of water across the evaporator and condenser.
Select a chiller to meet this load. Using PsychProcess. Since the SHRLoad is also a mid-range value. For additional information purposes.. Calculate the required condenser water flow based on 3.
Reduce flow to 15 gpm and by interpolation: Total 66 A four-zone building has the loads shown below.. Peak load occurs at 3 p. The peak block load occurs at 3 p. So Model HW-4 coil at cfm and 15 gpm will work. Zone 3: Use same coil as zones 1 and 2. EWT Compressor demand will be Specify unit model number.
Zone 4: Use same coil and water flow as zone 3 to meet 3 p. Use same coil and water flow as zone 1 to meet 10 a. Problem 6. Occupants are comfortable with a lower setting in the winter because they are typically dressed with heavier clothing because of the lower outdoor temperature.. In the winter? Why is there a difference? The temperatures are lower in the winter because occupants are typically dressed with heavier clothing in the winter because of the lower outdoor temperature.
Solutions to Chapter 6— Comfort. Specify the required ventilation airflow rate. The zone air distribution effectiveness EZ is 1. The ventilation air is delivered through ceiling vents and returned though a grille near the floor. In the case of the library.
It will mix with the room air and fulfill its intended effect before it is exhausted.. The zone air distribution effectiveness EZ is 0. Compute the required ventilation air rate in the summer and winter given the following table. Supply air: Chapter 6—Comfort. Ventilation air is supplied at the rooftop unit return. Determine the required ventilation air rate for a multi-zone ventilation air system.
The return is also in the ceiling. For Tuscaloosa from Table 6. Solution Problem This notation means that the value of the temperature in the table is exceeded during Elevation Dry-bulb temperature at 0. Surface Out.. Surface Out. Surface 0. Finish In. Assuming the 1 in.

Problem 8. Provide results for all three design conditions and compare with estimates given in Table 8. For Printout of 8 zones. Program will correct for temperatures. For Printout of 8 zones.. The shape of the room lends itself to two diffusers. Figure C. A four-way diffuser is appropriate.
Table 9. Figure C.. The solution should include a sketch. For a MERV 6. Use 24 in. Problem 9. One dimension should be a multiple of 24 in. The solution is demonstrated in the figure below. Provide a MERV 6 filter and limit total losses to less than 1. The solution is demonstrated in the figure below and in the spreadsheet sample on the following page.. L Plen Ret. Path 1. From Table See Eqv.
Equivalent Length Method.. Option 1 using Table 9. Equal Friction. Path 2 Roughness fpm Inches Feet Specify the required speed tap setting.
Select a motor and specify the resulting bhp and fan speed to provide 1. Select a belt-drive fan and motor to provide cfm at a TSP of 3. Specify the required fan pulley diameter for a rpm motor with an 8 in. Interpolation at cfm for 1. Interpolating between Use a 7. A fan speed of rpm Required 1. Provide the fan pulley diameter for a rpm motor with a 4 in.
Specify the required fan pulley diameter for a rpm motor with a 6 in. Q at rpm. Develop a system curve for both situations dampers full open and minimum and find the resulting flow when the fan is turning Prob 9. Estimate the required power at all six points. Fan curve lines represent results of Problem System curve for minimum damper found using: The distance between each FCU is 50 ft. Piping Loop Head Loss Calculator.. Fitting Selector Leqv Qty. The distance between the first FCU and the chiller is ft.
The fan-coils units are Model HW-4 Table 5. The chiller head loss is found using the specifications of a Model scroll compressor design Table 5. Liquid 2 T-Straight 6.

In this case. A more extensive set of pump curves should be consulted to select a pump that will operate at a more favorable efficiency. Graph Figure Use the Model chiller from Problem If the water treatment program is uncertain. It will require approximately 2.
A more extensive set of pump curves should be consulted to select a pump that will operate at a more favorable efficiency.. The system requires a pump that will deliver a gpm flow rate and 45 ft of head. The distance between the basin and upper tray in the cooling tower is 12 ft. Liquid 3 T-Straight 5.
