由ASHRAE（RP-1509[1]）赞助的最新研究开发了一种使用光反应器的UVC评估试验，并研究了UVC光降解对典型HVAC材料、组件和过滤器的影响，辐照度范围为每平方厘米1000至14000微瓦。研究表明，对于研究范围内的大多数材料，质量损失与UVC辐照度之间呈线性关系。然而，研究还表明，质量损失与辐照度的关系在每平方厘米1000微瓦以下是非线性的，这限制了暖通空调设计师和维修人员预测部件寿命的能力。

Recent research sponsored by ASHRAE (RP-1509 [1]) developed a UVC evaluation test employing photoreactors and investigated the effects of UVC photodegradation on typical HVAC materials, components and filters in the irradiance range of 1,000 to 14,000 microwatts per square centimeter. The research showed that the relationship between mass loss and UVC irradiance was linear for most materials in the studied range. However, the research also indicated that the mass loss versus irradiance relationship was nonlinear below 1,000 microwatts per square centimeter limiting the capabilities of HVAC designers and maintainers to predict component lifetimes.
