DUCT TYPE REFRIGERATING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a refrigerating system capable of refrigerating an item by a method showing a less amount of consumption energy. SOLUTION: This duct type refrigerating system is constituted so that a heat exchanger 7 of a CO2 pipe 10 forming a freezing cycle is a heating means for heating water kept in a body 1 of a hot water feeder, another heat exchanger 17 is a cooling means for use in storage medium 26; storage medium 26 cooled under an operation of the freezing cycle, air heat exchanged and cooled and non-cooled air are mixed through a damper 29; and air adjusted to a predetermined temperature is supplied to a refrigerating box 30 through a duct 28.
