Week 3 (19 to 25/8/2012)

For this whole week I was doing research for my project. I was looking for other similar temperature controlled cooling systems so I can differentiate it to my project and put it in the literature review of my project report. I did my research on the internet. One of the things that I found is thermostat.

A thermostat is a component of a control system which senses the temperature of a system so that the system's temperature is maintained near a desired setpoint. The thermostat does this by switching heating or cooling devices on or off, or regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A well functioning thermostat can be more advantageous than this project provide, as it basically works as air conditioner with automatic function. But since it needs air conditioner or heater to work, it is still considered to be expensive to be applied to standard home usage. Only wealthy people can afford it, for example smart home using separate thermostats in each room, since it also consumes more energy than standard fan.
