Description
Technical field
the utility model relates to a kind of condenser, particularly relates to the built-in enhanced heat exchange subcooler of a kind of shell and tube condenser structure.
Background technology
the method that refrigeration industry improves unit efficiency is a lot, and wherein forming suitable degree of supercooling is a kind of good method of effect.Degree of supercooling is saturated liquid temperature that condenser condenses pressure is corresponding and the difference of condensator outlet liquid actual temperature.When refrigeration system normal circulation, the outlet of condenser generally all can have certain degree of supercooling, if there is no degree of supercooling, liquid in two-phase refrigerant pressure in liquid pipe slightly loses, liquid will shwoot, saturated liquid is because the reduction of pressure will inevitably be evaporated, liquid evaporation can absorb heat around, remaining liquid is lowered the temperature thereupon, reach again the saturation temperature of relevant pressure, advance in two-phase refrigerant limit like this, limit shwoot, limit is saturated, until arrival evaporator inlet, the mass dryness fraction of the final two-phase refrigerant that arrives evaporimeter will be more much larger than the mass dryness fraction of design, liquid phase ingredient reduces, just cannot meet the evaporation capacity of evaporimeter, refrigeration does not reach requirement.
but existing condenser installation difficulty is large, expends man-hour, and the use amount of subcooler material is more, if subcooler adopts welding manner, because cylindrical shell is long and barrel dliameter reason, workman cannot enter cylindrical shell and weld.
