Title:
DUCT DEVICE AND COOLING METHOD OF REFRIGERANT PIPE
Document Type and Number:
Japanese Patent JP2007225153
Kind Code:
A
Abstract:

To substantially improve cooling efficiency by surely lowering an ambient temperature of a refrigerant pipe.

This duct device covering the refrigerant pipe 3 for air conditioning, comprises a duct body 5 covering the refrigerant pipe 3 positioned outdoors, of the refrigerant pipe 3 connecting an air conditioning outdoor unit 1 and an air conditioning indoor unit 10, and a water supply pipe fixture 7 for fixing a water supply pipe 6 allowing the water to flow along a surface of the duct body 5, and the drainage water generated in heat exchange by the air conditioning indoor unit 10 is allowed to flow on the surface of the duct body 5 through the water supply pipe 6. Thus rise of surface temperature of the duct body 5 is prevented by the water, and temperature rise around a refrigerant pipe 3 is prevented, even when the surface temperature of the duct body 5 is raised by sunlight irradiation to the surface of the duct body 5.
