Refrigeration moisture eliminating device and method

Patent ·
OSTI ID:6398773
Apparatus is described for removing moisture from a refrigeration unit. The refrigeration unit includes a compressor, a condenser and an evaporator coupled in a loop. The refrigeration unit further includes a low pressure side valve between the compressor and the evaporator and a high pressure side valve between the condenser and evaporator. The apparatus comprises: output coupling adapted for being coupled to the low pressure side valve when opened; input coupling means adapted for being coupled to a source of a dry gas; gas transfer and heating means, positioned between the output coupling means and input coupling means, for transferring and heating dry gas applied through the input coupling means to the output coupling means; sensing means for sensing the temperature and pressure of the dry gas transferred to the output coupling means; and means for manifesting the sensed temperature and pressure to indicate when to close the low pressure side valve.
