    Problem with cold room

    We prepared a cold room by our-self. Body material sandwich-panel, size: 6'X7'X8' (LXWXH), required temperature: 5-15 Deg C. For the cooling purpose we use a 2 ton spare split type AC outdoor unit, cold room cooling coil, danfross expansion valve & filter dryer. Controlling system with temperature sensor and controller as required.

    Our problem is, at first the system is running without problem after reaching required set temperature compressor stopped as required but not starting when required (As set temperature value). Our controlling system is ok.

    We are using R22 refrigerant. Compressor is taking 7-8 amp at running condition and it is normal.

    Compressor specification as follows: Mitsubishi, Model Number TH338, hermetic
