Evaporator is a component critically important in four big parts of refrigeration, and the condensed fluid of low temperature is by evaporator, with the external world Air carry out heat exchange, gasification heat absorption, achieve the effect that refrigeration.

Evaporator is mainly made of heating room and vaporization chamber two parts.It heats room and provides heat required for evaporation to liquid Amount, promotes liquid boiling to vaporize；Vaporization chamber is kept completely separate gas-liquid two-phase.

Column as: evaporator is also referred to as standard evaporator such as evaporator with central downcomer.Its heating room is by vertical Tube bank composition, the central circulating tube that centre has a diameter very big, the lesser heating tube of remaining caliber are known as boiling tube.Due in Entreat circulation pipe larger, the heat-transfer area that unit volume solution occupies, occupied than unit solution in boiling tube it is small, i.e., it is central Circulation pipe is different with solution heating degree in other heating tubes, so that the density of the liquid-vapor mixture in boiling tube is followed than center The density of solution is small in endless tube, in addition the upward swabbing action of upflowing vapor, and the solution in evaporator can be made to be formed by center Circulation pipe decline is circulated by what boiling tube rose.This circulation is mainly caused by the density contrast of solution, therefore is known as certainly So circulation.This effect is conducive to the raising of the heat-transfer effect in evaporator.

In order to make solution have good circulation, the sectional area of central circulating tube is generally the 40 of other heating tube total sectional areas ~100%；Heating tube height is generally 1~2m；Pipe diameter is heated between 25~75mm.This evaporator due to it is compact-sized, The advantages that easily manufactured, heat transfer is preferably and operation is reliable, application is very extensive.But due to the limitation in structure, circulation rate Less.In addition solution constantly recycles in heating room, its concentration is made to be nearly completed the concentration of liquid, thus the boiling point of solution always Height, effective temperature difference are reduced by.This is the common drawback of recirculation type evaporator.In addition, the cleaning and maintenance of equipment are also not square enough Just, so this evaporator is difficult to fully meet the requirement of production.

Condenser 12 (Condenser) is the parts of refrigeration system, belongs to one kind of heat exchanger, can be gas or steam It is transformed into liquid, the heat in pipe in a manner of cracking, passes in the air near pipe.Condenser working process is A exothermic process, so condenser temperature is all higher.

The inlet temperature of air intake 1 is less than or equal to 40 °, air after freezing from the temperature that air outlet slit 6 comes out be 5- 10°；For the environment temperature of entire refrigerator at 5-30 ° or so, operating pressure is 2- in 0.3-0.4Mpa, the dew point of air outlet slit 10 °, processing air quantity is 7.5M3/min.

Advantage: refrigerating efficiency promotes 25%, at the same avoid increasing expense caused by the extras such as chilled water pump and after The cost of phase operation, maintenance, the installation of unit is very simple, and primary Calculation can save the initial investment cost of 6-8% or so, section About 15% operation cost.

Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to In this, any those skilled in the art is in technical scope disclosed by the utility model, the change that can readily occur in Change or replace, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with described Subject to scope of protection of the claims.Unless otherwise defined, technical and scientific term used herein and to belong to this practical new The normally understood meaning of those skilled in the art of type is identical.It is used in the description of the utility model herein Term is intended merely to the purpose of description specific embodiment, it is not intended that limitation the utility model.
