HowanIceMachineWorks
Anicemachineworksbytransferringheatfromthewaterinsidetheicemachine,to
thecondenserthroughtherefrigerationsystem.Thecondenserfanexhauststhis
heatoutandawayfromtheicemachine.Thetransferofheatissoefficientthatit
freezesthewaterintotheevaporatormoldmakingicecubes.
NOTE:Iftheairflowisrestrictedorblockedoneithertheairinletorairoutletvents
theheattransferprocesswillnottakeplace.Thismeanstheicemachinewillmake
littleornoice.Itrequiresgoodcoolairflowthroughthemachinetooperate
effectivelyandefficiently.
EnsurethereisNOheatgeneratingequipmentnexttoorclosebytheicemachine.
