Details on the structure and operating principles of mobile cold storage.

For a system cold storage For mobile cooling systems to operate stably in a constantly circulating environment, engineers at Tan Long have optimized each component to ensure rapid cooling performance and absolute insulation capabilities.

Main components of a mobile cold storage system

Unlike traditional warehouses, mobile cold storage requires a durable and compact structure. The system's construction includes the following core components:

• Insulated warehouse shell (Panel): Constructed from high-density PU (Polyurethane) panels (40-42 kg/m³). The outer shell is usually covered with stainless steel or colored galvanized steel to increase mechanical strength and corrosion resistance when used outdoors.
• Refrigeration compressor unit: Acting as the "heart" of the system, the compressor (usually Bitzer, Mycom, or Refcomp models) performs the task of compressing the refrigerant from low pressure to high pressure.
• Heat exchanger system:
  • Industrial refrigeration system: Installed inside the warehouse to absorb heat from the goods, helping to lower the ambient temperature to the required level (from -25°C to +10°C).
  • Outdoor unit (Condenser): It is installed outdoors to dissipate heat into the environment, ensuring a closed and continuous cooling cycle.
• Cold storage door: Use sliding or hinged doors with multi-layered, cold-resistant rubber seals to completely prevent heat loss at the joints.
• Intelligent control system: Use PLC control cabinet Integrating remote monitoring technology via IoT allows business owners to precisely control temperature anytime, anywhere.

Operating principle of the mobile refrigeration cycle

The working principle of a mobile cold storage facility is based on the thermodynamic cycle of the refrigerant, which takes place in a closed system of four stages to maintain the ideal storage temperature.

Essentially, the compressor pushes the refrigerant, in high-pressure gaseous form, through the condenser coil to condense it into a liquid. This liquid then passes through the expansion valve to reduce pressure and temperature before entering the evaporator coil. Here, the refrigerant absorbs heat from the food/goods, evaporates back into a gaseous form, and returns to the compressor.

The detailed operating procedure includes:

1. Compression phase: The compressor sucks in refrigerant gas in vapor form and compresses it into high-pressure, high-temperature vapor.
2. Condensation phase: The hot air passes through the condenser, dissipating heat into the environment and turning into liquid.
3. Thrombotic phase: The liquid refrigerant passes through the expansion valve, causing a sudden drop in temperature and pressure (resulting in deep cooling).
4. Evaporation phase: The refrigerant enters the cooling coil, absorbs heat from the goods in the warehouse, cools the surrounding environment, and the gas turns back into vapor to start the cycle again.

Implementing this principle precisely not only helps preserve the freshness of goods but also saves businesses up to 30% of electricity consumption.
