This feature can furtherreduce power consumption and removethe inaccuracies and hassles caused byadjustments based on preliminaryexperiments. Tests operation achieves bothenergy savings and reproducibility/reliability.Parallel refrigerator controlsystem for energy-savingcontrol (Patent pending)To optimize further the power consumption,the chamber features a parallel controlsystem that connects two small refrigeratorsin parallel to the secondary side of therefrigeration circuit. The chamber canoperate at the optimal refrigeration capacitybased on the controlled temperature, byswitching operation between tworefrigerators simultaneously or a singlerefrigerator. At stable low-temperatureexposures, power consumption is alsoreduced by limiting refrigeration capacitywith an electronic expansion valve.Cold chamberLow-temp.exposureLow-temp.exposureStop operation Pre-cooling operation Stop operation Pre-cooling operation● Parallel refrigerator control system power during Eco operation(compared to previous chamber)Measuring used power(option: power meter)A wattmeter is provided as an option tomeasure the power consumed. It is alsopossible to halt a test by setting the stoptime. This function is useful for savingenergy.3emperature (°C)180160140120100806040Test area temperaturePower (kW)
