Cool and freeze containers are specialized containers used for the transportation and storage of goods that require temperature-controlled environments. These containers are designed to maintain a consistent temperature range to ensure that the contents are not affected by external temperature changes during transport or storage. Cool and freeze containers can be made of various materials such as plastic, steel, or aluminum, depending on their intended use and the temperature range required for the goods being transported or stored. They may be equipped with insulation, refrigeration systems, and temperature monitoring devices to maintain the desired temperature range. These containers are commonly used to transport and store perishable goods such as food, pharmaceuticals, and biologics, as well as other temperature-sensitive materials like chemicals and electronics. They come in various sizes, ranging from small containers used for transport by individuals to large containers used for commercial purposes. Cool and freeze containers are designed to keep the temperature of the stored goods at a specific level. The working principle of cool and freeze containers is based on the heat transfer principle. The containers are equipped with a refrigeration system that cools down the air inside the container to a specific temperature. The refrigeration system typically consists of a compressor, a condenser, an evaporator, and an expansion valve. The compressor compresses the refrigerant gas, which raises its temperature and pressure. The high-pressure gas then flows through the condenser, where it releases the heat it has absorbed and turns into a high-pressure liquid. The high-pressure liquid then flows through an expansion valve, where it is suddenly released into a low-pressure area, causing it to expand and cool down. The low-pressure gas then flows through the evaporator, where it absorbs the heat from the air inside the container, causing the air to cool down. The cooled air is then circulated inside the container using fans, which help to maintain a consistent temperature throughout the container. The refrigeration system continues to cycle, maintaining the desired temperature inside the container. In the case of freeze containers, the refrigeration system is designed to cool down the air to a much lower temperature, typically below freezing point, to freeze the stored goods. Cool and freeze containers typically include the following major components: 1. Insulated walls: The walls of cool and freeze containers are heavily insulated to prevent heat transfer from the outside environment. The insulation is usually made of materials such as polyurethane foam, polystyrene foam, or vacuum-insulated panels. 2. Refrigeration unit: The refrigeration unit is responsible for cooling or freezing the contents of the container. It typically includes a compressor, condenser, evaporator, and expansion valve. 3. Temperature control system: The temperature control system is used to maintain the desired temperature inside the container. It may include sensors, thermostats, and control panels. 4. Door: The door of the container is designed to minimize heat transfer and maintain the temperature inside the container. It may include a gasket to create an airtight seal. 5. Shelving and racks: Cool and freeze containers may include shelving and racks to organize and store the contents. 6. Power supply: The refrigeration unit and temperature control system require a power supply to operate. Some containers may have built-in generators or be designed to be powered by a vehicle or external power source. 7. Alarms and monitoring systems: Some containers may have alarms and monitoring systems to alert users if the temperature goes out of range or if there is a problem with the refrigeration unit. There are several key manufacturers of cool and freeze containers, including: 1. Carrier Transicold 2. Thermo King 3. Daikin Industries 4. Mitsubishi Heavy Industries 5. CIMC Group 6. Singamas Container Holdings 7. China International Marine Containers (Group) Co., Ltd. 8. Klinge Corporation 9. M&R Engineering 10. Cold Box Express 11. American Container Net 12. Cold Storage Manufacturing It's worth noting that some of these manufacturers specialize in refrigerated shipping containers for the transportation of goods, while others specialize in stationary refrigeration units for commercial or industrial use.
