I am doing a project for the university.
The project consists of a temperature controller in a glass chamber. The objective is a controllable temperature in a range of 0 - 100 degrees Celsius. The chamber volume is about 5 liters.
For the heating operation, I am going to use a typical heat resistor.
For the cooling operation, I am going to use a Peltier device. I have my reasons for not use this in the heating operation (I will be using a buck converter with fixed polarity.)
My question is about the following case:
- I heat the chamber to 100 degrees, once in the permanent regiment, it is possible to turn on the Peltier device to cool the chamber to 0 degrees (for example).
- What happens with the typical charts in the datasheets of the Peltier device, the dT is negative?
- Is an operation like this possible?
- Can somebody give me an abstract of the behavior of the Peltier cell in this situation?
