Résumé

The purpose of this paper is to introduce a new type of a drying system, which could improve the demerits of the conventional drying equipment. In the system developed, a vapour-compression heat pump is applied to utilize the exhaust heat from a condenser to heat wet material from the bottom of a closed chamber to generate vapour in the closed chamber. The vapour is dehumidified by an evaporator of the refrigeration cycle - consisting of a so-called heat recovery type drying system. As a refrigerant of the heat pump, R-410A is used, therefore, the new system is free from ozone depletion. Since in the developed system, it is possible to dry by the condensing temperature, there is no possibility of denaturing material. In order to compare the performance of the system developed, the authors compared it with a conventional hot-air system with an electric heater. As a result of the comparison, the system developed has been proven to consume less than about 1/3 of the electrical energy of a conventional system and to contribute thus to the prevention of global warming.
