Abstract:
1. A drying apparatus comprising: a heat pump apparatus in which a radiator and an evaporator of the heat pump apparatus are located inside an air circulation path of the drying apparatus; the heat pump apparatus contains a refrigerant which circulates through a compressor which is connected in line with the radiator which is connected in line with a throttle apparatus which is connected in line with the evaporator, in this order; and the air circulation path, being a closed loop without air exchange between and an inside and an outside of the air circulation path, contains air which is heated by said radiator before being introduced into a dry chamber, the air coming out from said dry chamber is cooled by heat exchanging with air outside of the air circulation path by a cooling apparatus downstream from the dry chamber, the air cooled by said cooling apparatus is dehumidified by said evaporator of the heat pump apparatus, the evaporator being located downstream from the cooling apparatus, and the air dehumidified by said evaporator is recirculated via the air circulation path to the radiator and is again heated by said radiator, with the compressor being connected to a compressor input detecting means for detecting input of said compressor, and the cooling apparatus being connected to a cooling quantity control means for controlling a cooling quantity of said cooling apparatus using a value detected by said compressor input detecting means.
