The Three Types of Refrigerator Evaporators and Their Performance (Fridge Evaporator)

 

 The three different types of fridge evaporators

 

 What are the three types of refrigerator evaporators? Let's examine the distinctions among roll bond evaporators, bare tube evaporators, and fin evaporators. A comparison chart will illustrate their performance and parameters.

 There are three primary construction types of refrigerator evaporators, each serving the purpose of removing heat from the air, water, and other items inside the refrigerator. The evaporator acts as a heat exchanger, facilitating the transfer of heat and ensuring a cooling effect. Let's explore each construction type in detail. 

When you think about the different construction types of refrigerator evaporators, you’ll find three construction types. Let’s take a closer look at each type.

 

 

 

 

  

Surface Plate Evaporators 

plate surface evaporators are created by rolling aluminum plates into a rectangular shape. These evaporators are a cost-effective option suitable for both household and commercial refrigerators. They have a longer lifespan and are easy to maintain. However, it is important to consider that their cooling effect may not be as evenly distributed compared to other types of evaporators.

 

 

 

 

 

  

Finned Tube Evaporators 

 Finned tube evaporators consist of a series of small metal plates arranged in an elongated strip form. They are commonly used in large commercial refrigeration systems and supermarket display cabinets. The main advantage of finned tube evaporators is their ability to provide a uniform and consistent cooling effect. However, it's important to mention that they generally come with a higher price tag compared to other types of evaporators.

 

 

 

 

 

 

 

Tubular Evaporators 

Tubular evaporators, also known as bare tube evaporators, are made of tubular metal and are designed to be installed on the back or side of a refrigerator unit. These evaporators are commonly used in household and small beverage coolers, providing a reliable cooling effect. However, they are less suitable for larger commercial refrigeration systems, like two or three-door commercial fridges.
