Abstract

PURPOSE:To control a cooler efficiently by continuously operating a compressor and at the same time, controlling a heater in response to the signal from a sensor when the temperature of a space is controlled in a narrow range, and operating no heater when the temperature is controlled in a wide range. CONSTITUTION:A heater 13 is provided with a refrigerator 8, and while a compressor 1 is kept running irrespective of the temperature at the inside of the refrigerator, the heater 13 is controlled by a signal from a sensor 11 and thereby the temperature in the refrigerator is devised to keep precisely at the set temperature. Further, when it is not necessary to control so precisely in the refrigerator 8 according to applied conditions an automatic analytical equipment, it is devised that the temperatue in the refrigerator is controlled through turning on/off of the compressor 1. Thus, it is possible to precisely control the temperature in a narrow range combining the compressor and the heater, and at the same time, use the compressor efficiently and prolong its working life.
