Automatic Cool Room Condenser and Evaporator Heat Exchanger

Direct heat source heating refers to the evaporation process of mixing fuel with air, causing the high-temperature flame and smoke generated by its combustion to be directly sprayed into the evaporated solution through a nozzle to heat the solution and vaporize the solvent.

Evaporators are divided into three types according to operating pressure: normal pressure, pressurized, and depressurized. According to the movement of the solution in the evaporator, it can be divided into: ① circulating type. Boiling solution passes through the heating surface multiple times in the heating chamber, such as central circulation tube type, hanging basket type, external heating type, Levin type, and forced circulation type One way type. The boiling solution passes through the heated surface in the heating chamber at once without circulating flow, and the concentrated solution is discharged, such as rising film, falling film, stirring film, and centrifugal film Direct contact type. The heating medium directly contacts the solution for heat transfer, such as an immersed combustion evaporator. During the operation of the evaporation device, a large amount of heating steam needs to be consumed. To save heating steam, a multi effect evaporation device and a steam recompression evaporator can be used. Evaporators are widely used in departments such as chemical and light industries.

Evaporation is the physical process of converting a liquid state into a gas state. Generally speaking, an evaporator is an object that converts a liquid substance into a gaseous state. There are a large number of evaporators in industry, among which the evaporator used in refrigeration systems is one of them. The evaporator is an important component among the four major refrigeration components. The low-temperature condensed liquid exchanges heat with the external air through the evaporator, vaporizes and absorbs heat, achieving the refrigeration effect. The evaporator mainly consists of two parts: a heating chamber and an evaporation chamber. The heating chamber provides the heat required for evaporation of the liquid, promoting its boiling and vaporization; The evaporation chamber completely separates the gas-liquid phases.
