Evaporator Coil for Reefer Container

Evaporator Coil for Reefer Container is the core component in the refrigeration system of refrigerated containers. The following is a detailed analysis of it:
I. Definition and Function

The evaporator coil for reefer container is a heat exchanger specially designed for use inside refrigerated containers. Its main function is to absorb the heat of the air in the container through the evaporation of the refrigerant, thereby reducing the temperature inside the container and ensuring that the goods maintain a constant low temperature environment during transportation.

II. Structure and Features

1. **Structure**:

* The evaporator coil is usually made of a series of copper or aluminum tubes filled with refrigerant.

* The outer surface of the pipe is covered with fins to increase the heat exchange area and improve the heat exchange efficiency.

* The fin material is mostly hydrophilic aluminum foil, which helps to quickly discharge condensed water.

2. Features:

* Efficient refrigeration: By optimizing the pipeline layout and fin design, the evaporator coil can achieve efficient refrigeration, ensuring that the temperature inside the container is quickly reduced and maintained constant.

* Strong corrosion resistance: Made of high-quality materials, it has good corrosion resistance and can adapt to various harsh transportation environments.
* Easy to maintain: The design structure is compact and easy to disassemble, which is convenient for cleaning and maintenance.

III. Working principle

The working principle of the evaporator coil of the refrigerated container is based on the principle of thermodynamics. When the refrigerant flows through the coil pipe, due to the temperature difference between the outer surface of the pipe and the air in the container, the refrigerant absorbs heat from the air and evaporates. This process consumes heat, so it can reduce the temperature of the air in the container. At the same time, the fan blows air over the surface of the coil, accelerating the heat exchange between the air and the refrigerant, further improving the refrigeration efficiency.

IV. Application scenario

The evaporator coil of the refrigerated container is widely used in various goods that need to be refrigerated for transportation, such as food, medicine, chemicals, etc. Especially in long-distance sea or land transportation, the refrigerated container can ensure that the goods maintain a constant low temperature environment during transportation, thereby preventing the goods from being damaged or deteriorating due to temperature changes.

In summary, the evaporator coil of the refrigerated container is one of the key components in the refrigeration system of the refrigerated container. By understanding its structure, characteristics, working principle and application scenarios, as well as performing regular maintenance and upkeep, we can better use and maintain these equipment, ensuring that refrigerated containers can maintain a constant low temperature environment during transportation and extend their service life.
