A refrigerating apparatus includes first and second refrigerant circuits including respective first and second compressors, condensers, pressure reducers, and evaporators, connected circularly with first and second refrigerant pipes, respectively, refrigerants discharged from the first and second compressors being respectively condensed at the first and second condensers and thereafter respectively evaporated at the first and second evaporators to acquire a cooling effect; a temperature sensor that detects a temperature of an internal portion of a cold storage cabinet, the first and second evaporators being disposed to cool the internal portion simultaneously; and a first control device that controls the first and second compressors such that the first compressor and the second compressor start being alternately operated each time a temperature detected by the temperature sensor reaches a first temperature, and are continuously operated until the detected temperature reaches a second temperature lower than the first temperature.

Refrigerating apparatus

A refrigerating apparatus for keeping an inside of a storage at a predetermined low-temperature state includes first and second refrigerant circuits including compressors, condensers, decompressors, and evaporators, connected circularly with pipings to form refrigerating cycles, the circuit having a first or second refrigerant sealed therein as a working refrigerant, a first sensor which detects a temperature of a cascade condenser constituted by integrating the evaporator of the first refrigerant circuit and the condenser of the second refrigerant circuit in a heat exchangeable manner, first and second controllers which control operation performances of the first and second compressors in a variable manner based on first and second sensor detected temperatures in order that the first and second sensor detected temperatures are first and second temperatures, respectively, and a second sensor which detects a temperature inside the storage.

There is provided a culture observation system by which even a culture other than an observation target culture can be cultured and observation can be properly performed by a microscope during culturing of the culture. A culture observation system S includes a culturing cabinetfor forming an environment suitable for culturing cells in a culturing roomand an image pick-up devicefor photographing a microscopic image of the cells. The image pick-up deviceincludes a light sourcewhich is provided in the culturing roomand a tablewhich is provided in the culturing roomto hold the culture as an image pick-up target, and a shelffor accommodating the cells is provided in the culturing roomother than the light sourceand the table
