Abstract
A refrigeration system which can reduce the amount of moisture permeating into the system, inexpensively and by a simple structure, is disclosed. Rubber hoses (7, 8) capable of absorbing vibrations are arranged on the discharge and the intake sides of a compressor (1). It was found that the amount of moisture in the system can be effectively reduced by reducing the amount of moisture permeating the rubber hose on the discharge side. A freezing limit line is set for defining to a predetermined level the amount of moisture in the system determined by the amount of the refrigerant sealed in the system, the amount of the lubricating oil sealed in the system, the amount of moisture permeation of the hoses (7, 8) and the number of the years elapsed after operation start. The hose (7) on the discharge side of the compressor has a smaller amount of moisture permeation than the hose (8) on the intake side. A hose having a moisture permeation not more than the freezing limit line during a predetermined service life is used as the hose (7) on the discharge side.
