What Is Evaporator And It's Types?
What is Evaporator?The cooling process takes place when the liquid fluid evaporates in the evaporator and draws the latent heat of evaporation from the environment. This situation is similar to the evaporation of the cologne we poured. Evaporator It is the device that provides heat extraction from the medium by means of which the refrigerant evaporates.The structure of the evaporator should be designed in such a way that it will take the heat of the refrigerated material to ensure good and rapid evaporation of the refrigerant by providing a good heat transfer and keep the pressure difference between the inlet and outlet of the refrigerant to a minimum housing.Although energy-efficient products are high initial investment costs compared to standard products, they pay themselves back in a very short time and are profitable in the ongoing process. It is appropriate to select high-efficiency products due to environmental problems.
Refrigerants can be produced in many different designs and dimensions in practice according to the circulating method of the liquid or air, refrigerant control type and application under the working conditions.
The structure of the evaporator should be designed to ensure good and rapid evaporation of the refrigerant, to provide a good heat transfer of the heat of the refrigerated material (air, water, brine, etc.), to receive a high efficiency and to keep the pressure difference (losses) at the inlet and outlet of the refrigerant to a minimum. the latter often contradicts the first two.That is to say, the conditions for a good heat transfer and good evaporation require that the internal and external surfaces become more indented and more easily wetted (more hairy), thus increasing the pressure losses. requires a frequently referred work pattern.
Evaporator Types can be divided into 3 main groups according to the characteristics of the application: (A) Evaporators used to cool gaseous substances (usually air), (B) Evaporators cooling liquid substances (Water, brine, antifreeze, methylene glycol, chemical fluid, etc.), (C) Evaporators refrigerating solids (ice, ice skating rink, metals, etc.)
