ENERGY SAVING COOLING METHOD FOR INDOOR LOWER STAGE TEMPERATURE AIR AREA DUE TO SPECIFIC GRAVITY DIFFERENT IN TEMPERATURE

摘要

PROBLEM TO BE SOLVED: To provide a comfortable temperature in a living space with low cooling energy, by a method wherein only air in a low temperature low stage living section having a low temperature through cooling in a temperature air area separated into upper and lower stage is caused to effect reflux due to an air specific gravity difference due to a temperature difference during cooling in a large scale building. ;SOLUTION: When, during cooling of the interior of a large scale, a temperature difference is high between hot air in the vicinity of the back of a roof and a living section such as a room work for, a small power-operated blower 4 is disposed in a downward state in a home position on a base 3 in a building intermediate position in an area retaining air in upper and lower stages separated into upper and lower stages according to a specific gravity difference in air due to the temperature difference, and blowers 5 are arranged sideways in juxtaposition in series at interval of a specified distance. An air flow ceiling (a) is formed by a plane air curtain by supply sideways air from a blower 5 group. A blower 4 group is operated as a cooled low temperature lower stage temperature air area is maintained in a state to be separated from high temperature hot air in the vicinity of the back of a roof. A reflux area of cold air only in a working area at a lower stage is produced, and energy is saved by comfortably cooling by a low calory cooler.;COPYRIGHT: (C)1999,JPO
