摘要： An object is to provide a refrigerating apparatus which eliminates a disadvantage that a refrigerant circuit is overloaded and which can safely be operated. The refrigerating apparatus includes a control unit (2) which starts the operation of a refrigerant compressor (11) of the refrigerant circuit (10) in response to an operation signal and which regulates an expansion valve (13) so that the temperature of a refrigerant in a water heat exchanger (12) becomes +80°C or more and so that the temperature of the refrigerant in an evaporator (14) becomes 0°C or less. The control unit (2) detects a state of a case where a cold storage amount in an ice cold storage tank (50) of an ice cold storage unit reaches a predetermined amount or more and a state of a case where the control unit (2) judges that a hot water storage tank (20) is full of hot water, after the elapse of a predetermined time from the start of the operation of the compressor (4), and stops the operation of the compressor (11) when one of the states is satisfied.
