“…The auxiliary monitoring station in the background can be a mobile phone or a computer, and the blind user's guardian can enable the monitoring function at any time by turning on the visible camera for real-time video signal monitoring. And to gain real-time monitoring of environmental condition parameters, the cane is equipped with several temperature and humidity sensors [4], which continuously collect information about the user surroundings and synchronously pass them to the analysis software of the Arduino controller for analysis, and alerting in case of abnormalities in the monitored parameters of the surrounding environment.…”

“…Thus, the transient response of a CRHS must be carefully analyzed for measurements in the environment, such as the outlet of FBRs where there are simultaneous changes in humidity and temperature. Experimental measurements in the literature show that CRHS might show anomalous measurements when there are humidity and temperature changes concurrently (Kaplya, Kaplya, and Silaev 2020). Kaplya et al (2020) presented a mathematical model for the CRHS humidity measurement process to explain this anomaly.…”

Kaplya et al (2020) presented a mathematical model for the CRHS humidity measurement process to explain this anomaly. Their model assumes that CRHS is an integrated microprocessor system that performs joint processing of humidity ratio and temperature (using an internal temperature sensor).…”

Desiccant-coated fixed-bed regenerators (FBRs) can achieve high effectiveness due to high ratio of energy transfer area to volume, and therefore, they are favourable air-to-air energy recovery exchangers for HVAC systems. However, unlike other types of energy recovery exchangers, the air properties (i.e., temperature and humidity) at the outlet of FBRs vary with time. The variations in outlet airflow properties can cause errors in measurements because the measurements include the FBR and sensors transient responses. In this paper, a numerical model is developed to evaluate the performance of desiccant-coated FBRs and their transient operation. The model consists of an exchanger model (FBR model) and sensor (temperature and humidity) models to distinguish the actual performance of the FBR alone from the measured performance, which includes both the FBR and the sensor's response. The model is validated with experimental measurements and available results in the literature. The model can decouple the measured response of the FBR and sensors to predict the FBR performance. This paper's main contribution is an insight into the complex heat and mass transfer processes in desiccant-coated FBRs and measurement sensors. The results of this paper could be used to provide practical recommendations for humidity measurements of different types of desiccant-coated FBRs developed for HVAC applications. Furthermore, the measurement requirements in the current testing standards (ASHRAE 84 and CSA C439-18 standards) for FBRs are examined. Recommendations from this paper could be implemented in future versions of these standards.
