1. A closed drying system, comprising:
- a vessel that includes a moisture-containing object and an air circulator; and
a compression refrigeration cycle section that includes;
a compressor;
a heating condenser that supplies heat energy to the object through a bottom of the vessel to generate moisture-laden air, which contains moisture in water vapor removed from the object, by evaporation of the moisture of the object;
a regulating condenser that adjustably exhausts waste heat out of the system;
an evaporator that is located inside the vessel and removes the water vapor from the moisture-laden air by refrigeration;
an expansion valve connected after a circulating passage that delivers coolant from the compressor through the heating condenser to the regulating condenser; and
a sensor that detects a temperature of coolant immediately before the expansion valve, from which temperature information the regulating condenser keeps a coolant temperature before the expansion valve at a constant level,wherein the air circulator circulates air between the object and the evaporator within the vessel whereby moisture-removed air with latent heat removed will contact with the object.

Abstract
In a drying system using a compression refrigeration system, a condenser is divided into a regulating condenser and a heating condenser. The regulating condenser is capable of regulating the amount of exhaust heat discharged to outside the system. The heating condenser produces moist air by feeding heat to an aqueous object to be dried placed in a processing vessel to evaporate the moisture in the object. Heat of condensation of steam is recovered by an evaporator as heat of a refrigerant, and the recovered heat is discharged in the heating condenser to use it for the vaporization of the moisture in the object, and excess heat is discharged by the regulating condenser to outside the system.
