1. A process for accommodating an increase in the refrigerant pumping capacity of a compressor in an electrical transport refrigeration unit, said refrigeration unit being controlled by a microprocessor, said process comprising the steps of:

  • i. increasing the restriction of an electronic expansion valve, thereby reducing the mass flow rate and the current draw of the transport refrigeration unit;

    ii. subsequently de-energizing an unloader, thereby increasing the mass flow and current draw of said transport refrigeration unit;

    iii. gradually removing the increased restriction of said electronic expansion valve after said unloader has been de-energized, thereby maintaining the current draw of said transport refrigeration unit below a preselected limit.
