13. heat The capillary one ends in the entrance of the evaporator EVAPORATOR The evaporator is the component in which the coolant liquid is transformed to the gassy state when absorbing the heat of the interior of the cabinet taking place with this the coolant effect Inside the evaporator a low pressure exists since the coolant liquid has gone by the capillary one this pressure drop causes that the liquid evaporates to a low temperature All the heat that is absorbed in this phase gets lost in the condensation phase El especialista en servicio de linea blanca The Evaporator is united in its initial end to the capillary tube and in its final end to an accumulator necessary in the system to store the coolant liquid that didn t reach to evaporate in this phase since for the efficient operation of the system should not pass liquid toward the suction tube nor the compressor UNSOLDER THESE TUBES PPER APPENDIX Zi COPPER APPENDIX EPOXY WELDING JJ alle ACCUMULATOR EPOXY WELDING ALUMINUM TUBE The evaporator is manufactured of aluminum tube with thorns or fins that in the exterior to increase its efficiency of absorption of heat When it is required to replace the evaporator it is necessary to do it together with the accumulator since the evaporator is together to the accumulator with epoxy welding not available for the technicians of service unsolder of the copper appendixes indicated in the figure SUCTION

16. into the tube considerably long of the evaporator The evaporator is at a low pressure because of the suction inside the compressor this way the spontaneous pressure decrease causes that the liquid gets vaporized and absorbs heat The heat in the interior of the cabinet is transferred through convection to the evaporator because the evaporator temperature is lower than the airs At the moment of flowing out from the evaporator all the refrigerating liquid has been evaporated so only saturated or slightly overheated vapor returns to the compressor through suction REPAIRS This manual is intended to explain how the main components work and how to replace them in case they are replaceable parts and also some general recommendations to detect certain failures considering that each service requires a particular diagnosis depending on the failure description besides the assumption that the technician has the proper knowledge for diagnosing and repairing the failure This manual must only be used as a guide For the replacement of components of the refrigerating unit or the electric system it is assumed that the technician has disconnected the unit form the power before to initiate any repairs besides he has unsoldered the necessary joints as well as welded them again to finish the service and also that the refrigerating of the unit has been emptied from or loaded to the unit whenever required El especialista en servicio de linea blanca md
