The main material used to construct the walls of a polyurethane injection refrigerator is polyurethane foam. By utilizing a process known as 'high-pressure injection,' an internal foaming substance is injected into the component cavities, subsequently expanding to fill them completely. This technique not only provides excellent insulation but also lightens the weight of the refrigerator for transportation purposes.
PU Foam Refrigerators
PU foam-fridge panels are constructed using injection technology, which creates a seamless look. The panels are filled with PU foam that offers insulation. These refrigerator boxes are lightweight and are used in the transport of things like food and medicine. This is because they use PU foam technology that provides good insulation, which provides the fridge sustenance a long-lasting cold or heat to preserve what is inside.
Vacuum Refrigerators
Vacuum refrigerators function using the principle of thermal insulation. To avoid heat transfer from the outside environment, these fridges create a vacuum between the walls. Because there is no air in the space to transfer heat, this method effectively keeps the desired internal temperature. Because of this, vacuum refrigerators are excellent at keeping things cool, even in extreme temperatures.
EPS Refrigerators
EPS stands for expanded polystyrene, which is often referred to as styrofoam. The panels of a fridge with EPS are made of styrofoam. To keep things cool, the EPS refrigerator uses thermal insulation and dense ice at the bottom. Ice can be used to maintain the dolly bottom fridge's temperature when there is no electricity.
XPS Refrigerators
In contrast to EPS, which has two-dimensional spheres, XPS stands for extruded polystyrene. This is a type of thermal insulation that is frequently used to produce foam that has a rigid structure. Because of its resistance to heat transfer, XPS offers good insulation. The composition of a refrigerator's outer wall makes it quite energy-efficient.
These types of refrigerators cater to diverse requirements and operating environments in the food industry, pharmaceutical sector, logistics, and transportation businesses, among others.
The performance and durability of the refrigerator depend on proper maintenance and knowing the essential specifications of refrigerators with polyurethane injection.
Refrigerator Dimensions:
Knowing a refrigerator's dimensions is vital for selecting the right freezer for food storage. Buyers have to consider the height, width, depth, and interior layout for organizing items efficiently. It's all about making sure the freezer fits well and can effectively store perishable food. Typically, a commercial refrigerator mesure: between 74.8 - 78.7cm in height, 51.2 - 61cm in width, and 66 - 72.5cm in depth.
Refrigerant:
Refrigerants play a critical role in refrigerators' operation. Therefore, selecting a suitable cooling agent ensures efficient performance. The refrigerator's design determines which refrigerant it uses. For example, some refrigerators use R134a, commonly found in car air conditioners, while others may use R600A or R290. These options are both effective and eco-friendly, reducing harm to the ozone layer.
Storage Capacities:
Storage capacity signifies the amount of food items an area can hold. It's also an important metric for commercial refrigerators. Typical storage capacity for commercial refrigerators is as follows: mini refrigerators can store up to 60 liters, bar refrigerators give a storage of about 98 liters, display refrigerators have a storage capacity of 324 liters, and under-counter refrigerators can store up to 165 liters.
Energy Efficiency:
Energy efficiency in a refrigerator refers to how well it uses electricity to keep items cold. A good energy-efficient refrigerator minimizes power use while maintaining excellent cooling. Choosing a highly efficient model saves significant energy costs over time. Additionally, it reduces environmental impact by lowering carbon emissions. With energy labels showing their efficiency levels, buyers can select refrigerators that will save them money in the long run.
Proper maintenance is an essential requirement to keep the refrigerators with polyurethane injection in good condition. It ensures that the refrigerators continue to work optimally, and it also prolongs their shelf life. Below are some refrigerator maintenance tips:
Clean Condenser Coils:
Regularly cleaning the fridge's condenser coils is important for maintenance. The coils, usually found at the back or underneath, allow heat to escape. Dust buildup makes heat transfer harder, forcing the motor to work harder. This wears it out faster. So, cleaning those coils keeps cooling efficient and easy.
Check Door Seals:
Door seals on a refrigerator are actually the flexible rubber gaskets located around the door's edge. These gaskets create a barrier when the door closes and allow the refrigerator to keep cool without using much energy. It's crucial to routinely inspect the door seals since a damaged or dirty seal can't lock in the cold air. As a result, the appliance will expend more energy to maintain coolness.
Keep Fridge Organized:
Refrigerator organizing refers to arranging food items neatly for storage and easy access. It's important to maintain freshness and prevent waste. Expired food and spoiled odors can be avoided by routinely checking for expired items and discarding them promptly. An organized fridge promotes proper air circulation, ensuring even cooling throughout. This helps perishable foods stay fresh longer. Also, organizing makes meal prep easier and saves time spent searching for ingredients.
Refrigerator injection we can say is the backbone of cold preserving food items, goods, supplies, and pharmaceuticals for millions of people all around the world. These refrigerators are a living legend in the medicine, food and beverage, vaccine and e-commerce industries.
In the food and beverage industry, the refrigerator is used to provide cold drinks to people, and food items that require a cold temperature to stay fresh are kept in the fridge. This includes dairy products like milk and cheese, meats, fruits and vegetables, displays of products like cosmetics and pharmaceuticals, etc.
In the medical industry, vaccines must be kept in a refrigerator so they don't lose their effectiveness. This is especially true for temperatures ranging from 2 to 8 degrees Celsius. Besides vaccines, certain medications, biological samples and medical equipment and instruments are also stored in a refrigerator.
In the e-commerce world, when shipments are made for food, beverage, and medical products that require a certain temperature to be maintained, refrigeration injections are used to keep those items fresh until they reach their destination.
