Chapter 16, Problem 1RQ
What is the purpose of an air-conditioning control system?
Expert Solution & Answer
To determine
The purpose of air-conditioning control system.
Explanation of Solution
An air-conditioning system uses many electrical loads to maintain the desired temperature required by the occupants in a structure. The typical electrical loads involved in air-conditioning system are listed below:
- Blower
- Fan motor
- Compressor
- Furnace
In order to organize the operations of the above mentioned electrical loads, a control system is required. The control system must operate the respective component (electrical load) on a call for cooling and heating. The process of cooling involves compressor and fan motor. The process of heating involves furnace and blower.
Thus, the air-conditioning control system is intended to monitor the operation of an air-conditioning system.

Q1: Determine the length, angle of contact, and width of a 9.75 mm thick
leather belt required to transmit 15 kW from a motor running at 900 r.p.m. The
diameter of the driving pulley of the motor is 300 mm. The driven pulley runs at
300 r.p.m. and the distance between the centers of two pulleys is 3 meters. The
density of the leather is 1000 kg/m³. The maximum allowable stress in the
leather is 2.5 MPa. The coefficient of friction between the leather and pulley is
0.3. Assume open belt drive.
5. A 15 kW and 1200 r.p.m. motor drives a compressor at 300 r.p.m. through a pair of spur gears having
20° stub teeth. The centre to centre distance between the shafts is 400 mm. The motor pinion is made
of forged steel having an allowable static stress as 210 MPa, while the gear is made of cast steel
having allowable static stress as 140 MPa. Assuming that the drive operates 8 to 10 hours per day
under light shock conditions, find from the standpoint of strength,
1. Module; 2. Face width and 3. Number of teeth and pitch circle diameter of each gear.
Check the gears thus designed from the consideration of wear. The surface endurance limit may be
taken as 700 MPa. [Ans. m = 6 mm; b= 60 mm; Tp=24; T=96; Dp = 144mm; DG = 576 mm]
