摘要： PROBLEM TO BE SOLVED: To provide a ceiling embedded type air conditioning system reducing the installation time and cost by facilitating the structure and reducing the disposal cost by reducing discarded materials produced from ceiling materials and ceiling aggregate. SOLUTION: This ceiling embedded type air conditioning system comprises by assembling a simple construction ceiling formed by combining the T-shaped ceiling aggregate 1 framed into a grid shape with the ceiling materials 2, and is formed by attaching a heat exchanger 3, a connecting duct 12 to be connected to an air conditioner body 6 having an air blower 4, and an air outlet 8 to be connected to the connecting duct 12 to the simple construction ceiling. The external dimension of the air outlet 8 is set to the same dimension with the ceiling material and the air outlet 8 is mounted on the T-shaped ceiling aggregate 1. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an ultra-low temperature freezer having excellent cooling efficiency, and allowing easy assembling of a cooling pipe. SOLUTION: This ultra-low temperature freezer has a storage box 10 comprising a heat insulation door 2 and a heat insulation casing 1 having a storage chamber 3 for storing a cooled article. The heat insulation casing 1 comprises: an internal tank 1b forming the storage chamber 3; the cooling pipe 4 installed along the outer face of the internal tank 1b, for making a refrigerant of an ultra-low temperature flow as an evaporator of a refrigerator; a cover member 5 sandwiching and storing the cooling pipe 4 together with the internal tank 1b; a heating liquid medium 6 sealed in an airtight space between the internal tank 1b and the cover member 5; an external tank 1c forming a double wall together with the internal tank; and a heat insulation material 1a filled between the external tank 1c and the cover member 5/internal tank 1b. By using the heating liquid medium 6, a heat transfer face from the cooling pipe 4 to the internal tank 1b is enlarged, and the assembling is facilitated. COPYRIGHT: (C)2005,JPO&NCIPI
