HEAT TRANSFER FACTORS FOR HEAT STORAGE TYPE HEAT EXCHANGE AND METHOD OF USE THEREOF

摘要

The elements are in the form of rigid hollow balls (1), the interior of which are wholly or partially filled with a latent heat storage material. Heat transmission from a hot to a cold region is effected by cyclic transport of the balls between the hot and cold regions by means of a Ljungström heat exchanger or in a column heat exchanger. The balls are cleaned by frictional contact with one another as a result of their movement in a fluidized bed in the exchanger, or by rotation of a static bed in a rotary heat exchanger. The heat storage material may be a metal or a chemical compound, e.g. LiH, LiF or MgF2. IMAGE
