Summary

An analytical model is presented for predicting the effectiveness of rotating air-to-air energy wheels using only the characteristics measured on the same non-rotating wheels exposed to a step change in temperature and humidity. A relationship between the step change response and the periodic rotating response of an energy wheel is developed assuming that the energy wheel behaves as a first order linear system for water vapour and sensible energy exchange. This allows the prediction of the effectiveness of an energy wheel when only the characteristics of a stationary wheel exposed to humidity and temperature step responses are known. This paper develops effectiveness correlations and uncertainty bounds for sensible and latent effectiveness of energy wheels using data from transient measurements.
