A Circuit Design for Portable Cooling and Heating System Based on STC89C52RC MCU

Abstract:

Thermoelectric Cooler (TEC), with typical advantages such as low acoustic noise, small volume, lightness, high performance and high reliability, is a compact device widely used in fields like military applications and cooling or heating small spaces. Circuit design of a real-time controlled, LED displayed and monitored cooling and heating system is presented in this paper. The system is consisted of STC89C52RC MCU, TEC1-12706, temperature monitoring chip DS18B20, LED temperature display unit etc. Five kinds of functions like heating or cooling automatically adjustable, temperature controlling, temperature real-time displaying and monitoring and limitation value settings are achieved. A high cooling/heating efficiency has been obtained. The test result shows that the temperature rise/decrease can be 6,83°C/2.18°C per minute in the early 5 operation process of this system.
