Description

一种基于红外传感技术的室内舒适健康环境控制辐射空调系统 技术领域
本发明属于暖通空调技术领域，具体涉及一种基于红外传感技术的室内舒适健康环境控制辐射空调系统。
 背景技术
随着社会的不断发展及人们生活水平的不断提高，室内舒适健康环境已成为空调系统控制的目标。然而，目前的空调系统室内控制参数一般为空气温湿度和二氧化碳浓度。根据热舒适及健康理论，影响人体热舒适及健康的直接参数是人体表面温度及新风量。而室内空气温湿度和二氧化碳浓度作为影响人体热舒适及健康的间接参数，虽然一定程度上能反应室内环境的舒适健康水平，但大部分情况下很难完全满足室内舒适健康环境要求。因此，为了完全满足室内舒适健康环境要求，人体表面温度及新风量应该是空调系统室内控制参数。
辐射空调系统作为一种新型温湿独立控制系统，包括辐射供冷系统、独立新风系统及冷源等组成。由于辐射供冷末端通过辐射热交换作用可以直接作用于人体表面，相对于传统对流末端可以有效地控制人体表面温度及舒适水平。而独立新风系统通过通风换气作用供应清新空气能保证室内健康水平。因此，辐射空调系统如果设计及控制合理应该能完全满足室内舒适健康环境要求。
 技术问题
然而，目前的辐射空调系统室内控制参数仍是空气温湿度和二氧化碳浓度，无法充分发挥出辐射空调系统优势。这主要是由于缺少室内除湿末端，完全依靠独立新风系统进行除湿，如此导致新风系统不仅要控制二氧化碳浓度还得控制空气湿度。由于二氧化碳浓度和空气湿度控制均通过改变新风量实现，两者相互影响导致新风量无法精确控制，从而无法保证室内健康水平。此外，辐射供冷末端表面温度较高及铺设面积较少，导致与人体表面之间的辐射热交换作用效果不够显著，无法精确地控制人体表面温度及舒适水平。
 技术解决方案
本发明的目的是提供一种基于红外传感技术的室内舒适健康环境控制辐射空调系统，一方面通过显著提高辐射末端与人体表面之间的辐射热交换作用，实现人体表面温度及舒适水平的精确控制；另一方面通过解耦室内湿度及空气清新度控制，实现室内新风量及健康水平的精确控制。
