Refrigerated Container House Design

The design of refrigerated container houses requires comprehensive consideration of multiple factors such as functionality, structure, thermal insulation, and loading/unloading. Here are the specific design points:

Functional Adaptation Design

Refrigerated container houses are mainly used for storing temperature-sensitive goods, such as fresh food and pharmaceuticals. During the design process, the internal space layout should be determined according to the type of goods to ensure that the goods can be reasonably stacked and fixed, preventing damage during transportation or storage. For example, for different types of fresh produce that require partitioned storage, movable partitions can be designed to facilitate space adjustment according to actual needs.

Structural Strength Design

The frame structure of a refrigerated container is crucial for ensuring its load-bearing capacity. The frame mainly consists of front and rear end beams, left and right side beams, and corner posts. The wall and roof panels are generally made of corrugated steel plates, which have high strength and rigidity. The corrugated shape can increase the bending resistance of the steel plates. During the design process, materials should be reasonably selected and dimensions determined according to the expected load to ensure that the container will not suffer structural damage during transportation and storage. Generally, the rated load of dry cargo containers is around 20 - 30 tons, and refrigerated containers should also meet corresponding load-bearing requirements during design.

Thermal Insulation Design

Refrigerated containers need efficient thermal insulation layers to ensure good thermal insulation performance. Polyurethane foam and other thermal insulation materials are commonly used, with a thickness of around 80 - 100 millimeters. The design of the thermal insulation layer should effectively prevent external heat from entering and maintain a stable low-temperature environment inside. At the same time, the airtightness of the container is also crucial. The doors should be well-sealed to prevent rainwater and dust from entering, and rubber sealing strips are generally used for sealing.

Refrigeration System Design

The refrigeration system is the core part of a refrigerated container, including components such as compressors, evaporators, and condensers. During the design process, appropriate refrigeration equipment should be selected according to the volume of the container and the temperature range required by the goods to ensure that the internal temperature can be quickly and effectively reduced and maintained stably. In addition, the energy consumption and maintenance convenience of the refrigeration system should also be considered. Using energy-efficient equipment can reduce operating costs.

Loading/Unloading Function Design

To facilitate the loading and unloading of goods, refrigerated containers can adopt corner fitting designs, allowing cranes to lift them through the corner fittings. For containers with side doors or double doors, the door dimensions should be designed considering the maximum size of the goods to ensure that forklifts or pallet trucks can enter and exit smoothly.
