For any  refrigeration  system to  function  properly all 
components 
must be  in good  working  order. The  unit 
cooling  cycle  and the  relationship  between  air 
discharge  temperature  and ambient  temperature  and 
pressures  at the  compressor  can  help 
to 
determine proper operation  of the  system. 
The  length  of any  cooling  cycle  is determined  by 
such  factors  as ambient  temperature  and humidity,
