The controller will maintain the best comfortable air conditioning space and automatically adjusts the indoor temperature and humidity using least enthalpy estimator (LEE) to replace to traditional controller using constant temperature setting. Through the liquid crystal display, the user will understand the environment state and feel comfortable at any time. The controller creates a comfortable living space to achieve the purpose of air-conditioning. This paper uses the processor of ARM7-TDMI structure as the system kernel. It integrated several kinds of sensors and circuits into the hardware system. The embedded system structure will be developed as the HVAC Comfort controller. The characteristics of embedded system are small volume, low cost, high stability and also can combine the network for the future network monitoring. To judge the comfort of the air-conditioning, it used the least enthalpy estimator (LEE) to automatically determine the comfortable degree of best operating points in psychrometric chart. When it obtains the indoor temperature and humidity setting, it will forecast air-conditioning load according to Neural Network control theory and determine the output of fan-coil unit. Finally, the system achieves the purpose of saving energy and keeping comfortable. Yu-Wei Huang 黃裕煒 2006 學位論文 ; thesis 72 zh-TW |
