In order to spread its practical use to such scopes as sweltering hot con-trol cabins in the metallurgical shops and that on the traveling machines forfield work at subtropical zones, an analogous test with hot air for the semi-conductive thermoelectical air-cooling conditioners and investigations have beentaken based on former research.This paper is written with an attempt to de-duce the relation between the input air temperatures both on heat and coldsides and the cold quantities and the relation between the input air temperatureand difference in temperature, thus expressing a considerable fact that thecold quantities increase slowly instead of decrease with a rise in temperatu-re of input air. It has been also verified by test. Such an air-cooling condi-tioner is available to the sites environed by the air haviag a temperaturebelow 50°c. The difference in temperature of cooling effect isn't less than 14℃as 30A working current and 386 pairs of semiconductor blocks.

为将风冷式半导体空调扩大应用于冶金高温车间的操纵室和亚热带各露天作业的大型移动机械的司机室上,在过去“风冷式”诸参数研究的基础上,又用低于50℃的热空气进行了模拟实验与研究。本文从理论上推导出热端与冷端进口空气温度与致冷量、温差之间的关系式,说明随进口气温的升高,致冷效果不但并未降低,反而略有提高。这已由实验证实。在工作电流30A、元件386对、风量适当时,则致冷温差不低于14℃,可用于环境温度低50℃于的场所。

In order to extend the industrial application of the semiconductor air condi- tioner to thooe fields where ventilation problems were to be alleviated, such as sweltering control cabins in metallurgical plants and on traveling machines for outdoor activities in subtropical areas, an analogous test of a thermoelectric air cooling equipment with hot air input controlled below 50 degrees centigrade, was conducted on the basis of the previous studies of "air cooling" parameters. A quan- titative relationship between the temperature of the input air on both heat and cold sides and the refrigeration amount is deduced in this paper. Mathematical eva- luation shows that as the temperature of the intake draft rises, the cooling effect is not diminished and quite the contrary, it gets a little higher. This theoretical statement has been proved by experiments. The temperature difference generated by the cooling effect was not less than 14 degrees centigrade while the working current being maintained at 30 amperes.
