摘要：

An electrical storage heater utilizing off-peak electricity, usually available at night, was developed, and its performance has been tested experimentally and theoretically. Heat was stored as latent heat of fusion of a commercial paraffin wax, in an effort to reduce the heavy weight of the existing storage heaters that use the sensible heat method of storage. The PCM was contained in multi-units arranged to supply the necessary heat to the air flowing between them during the heat discharge cycle. Heat was supplied to the units at a low heat flux using an electrical heater fixed at the center axis of each unit. It was possible to describe the performance of the storage heater during both charge and discharge cycles using a one-dimensional model that included the effect of natural convection in the melted wax. The computer model predicted the performance of the storage heater sufficiently well to be used for the design of larger units. © 1990.
