METHOD FOR CONTROLLING ENERGY CONSERVATION OF COLD HEAT IMPACT TESTER

摘要

PROBLEM TO BE SOLVED: To generate a large difference at a mean temperature and to acquire a sufficient energy conservation effect by starting a heating means immediately before exposing with a high temperature, heating a high temperature room to a predetermined temperature, and then exposing it with a high temperature. ;SOLUTION: Even in a high temperature exposure operation, a heater 2a is operated in a high temperature room 2, an agitating fan 2b is rotatably driven, and dampers 4a, 5a are opened to supply high temperature air of a predetermined temperature to a testing room 1. Meanwhile, in a low temperature room 3, during this high temperature exposure operation, a precooling operation is executed by a time chart similar to that of the high temperature room. That is, the room 3 is naturally temperature raised without operating a refrigerator 3a immediately before the low temperature exposure, and operated so as to cancel a heat quantity supplied by a natural temperature rising of the refrigerator 3a immediately before the low temperature exposure, and the room 3 is precooled. In order to prevent supercooling by the refrigerator 3a after this precooling is started, a heater installed in the room 3 is suitably turned ON, OFF to regulate its temperature.;COPYRIGHT: (C)2001,JPO
