Title:
CONSTANT TEMPERATURE HIGH HUMIDITY CHAMBER
Document Type and Number:
Japanese Patent JP3199434
Kind Code:
B2
Abstract:
PURPOSE: To causes the flow of cold air, flowing out from a vaporizer, through a gap between an interior box body and an inner body at a low speed, to cause the rapid flow thereof through a suction duct, and to improve the efficiency of heat- exchange of the surface part of the interior box body by a method wherein a plurality of suction ducts running to a blower is arranged on the interior box body side of the interior box body and the inner box.
CONSTITUTION: When a compressor 13 in a machine room 8 at the upper part of a body 1 is run, cold air fed from a blower 14 through a vaporizer 15 flows through a rear plate 19, partitioning plates 23A-23F, side plates 20A and 20B, and air duct communicated to a space part 22B from a space part 22A between an interior box body 17, partitioned by a lower plate 21, and an inner box 3 as heat-exchange is effected. The cold air circulates a cycle wherein the air velocity of the cold air is increased from an opening part 30A of suction ducts 29A and 29B and returned through an opening part 30B to the blower 14. In this case, since the sectional areas of the openings of the suction ducts 29A and 29B are decreased to a value lower than that of the space part 22B, the air velocity of return cold air is increased compared with a case of the whole of the space part 22B forming an air duct for return cold air, and the occurrence of a fluctuation in the surface temperature of the interior box body 17 is reduced.
