Textbook Question
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.

The regenerator has an effectiveness of 79 percent, and the air enters the turbine at 1400 K. Assume constant specific heats for air at room temperature. The properties of air at room temperature are cp = 1.005 kJ/kg·K and k = 1.4. For a turbine efficiency of 90 percent, determine the amount of heat transfer in the regenerator.
