Title: Refrigeration unit
Inventor: TAIRA SHIGEJI
IPC: F24F11/02
Filed: 2002-05-20
Abstract: PROBLEM TO BE SOLVED: To provide a refrigeration unit where a temperature rise that might bring on a hamper on the function of constituent parts is avoided, and long service life is ensured. SOLUTION: A refrigeration unit is adapted, such that temperature sensors 11, 12, 13, and 14 respectively measured the temperatures of an outdoor heat exchanger 1, an indoor heat exchanger 5, a discharge piping 7A, and a compressor heat. A life calculation section 22 calculates the service lives of parts (a pressure reducer 3, and a compressor 7) constituting a refrigerant circuit, based on oil temperature derived by an oil temperature derivation section 21. A service life determining section 23 determines whether or not the service life calculated by the life calculation section 22 is above a predetermined value. When it is determined that the foregoing service life is not higher than the foregoing predetermined value, it derives an outdoor fan 2, an indoor fan 6, a pressure reducer 3, and the compressor 7 to reduce the oil temperature.
