Title: REFRIGERATION CYCLE DEVICE
Abstract:
An expensive storage battery is necessary in order to maintain cooling capacity day and night in a refrigeration cycle device that employs a solar battery as a power source. This refrigeration cycle device (100) comprises: a power source circuit unit (2) that boosts the voltage (Vo) generated by a solar battery (1), and that generates an alternating voltage (Vac) having a predetermined frequency; and a refrigeration stocker (3) in which the internal temperature is controlled by a compressor (31). The power source circuit unit controls the frequency of the alternating voltage to be supplied to a motor (M) of the compressor so as to maintain the voltage (Vo) generated by the solar battery at an input voltage setting value.
