Rational Planning
Making Cold Storage More Energy-Efficient, Safer, and Higher in Efficiency
Energy Conservation
In cold storage operations, potential energy loss can occur at every corner. At the loading bay, typical dock levelers under sectional doors can result in gaps between the leveler and the pit, exposure to outdoor temperatures, and poor sealing between the truck and the cold storage—all contributing to energy loss and higher operational costs. Conventional cold storage doors, with their poor sealing and low speed, are a primary source of inefficiency.
- Cold loss prevention and energy efficiency should be top priorities during planning, construction, and renovation.
Environmental Control
Due to the sensitivity of goods stored in cold storage, improper sealing during loading/unloading is highly detrimental. Energy loss, air exchange, and temperature fluctuations can cause spoilage, contamination, food safety issues, and decreased employee comfort.
- Addressing the sealing challenge for various truck sizes is a key planning concern.
Safety
During cargo handling and loading/unloading, safety for personnel, cargo, equipment, and vehicles is critical. Cold storage loading areas are busy zones with mixed traffic, and poor insulation and sealing lead to heavy condensation, slippery surfaces, and increased accident risk. Inside the cold room, floor icing becomes hazardous for vehicles and workers.
- Proper design, product selection, and regulated operation ensure safe cold storage operations.
Efficient Operation
Automatic door operation is essential for energy conservation, yet traditional doors open and close slowly, delaying drivers and impacting productivity. They’re also prone to damage and hard to repair, causing downtime.
- Choosing high-speed, impact-resistant, low-maintenance, and durable cold storage doors is imperative.

- Defrosting and de-icing processes consume time and labor.
- Increased electricity bills due to longer cooling times and inefficiency.
- Food safety risks from temperature fluctuations and air contamination.
- Frequent damage from forklifts; steel doors are hard to repair.
- Condensation and ice formation on floors raise accident risks.
- Refrigeration system damage due to moisture and ice on evaporators and coils.
- High costs and labor required for ice removal from ceilings and equipment.

Energy Saving Calculation Example
For a cold storage using ammonia refrigeration:
- Internal temp: -18°C
- External temp: 10°C
- Internal RH: 26%
- External RH: 60%
- Door usage: 15 open/close cycles per hour, 24/7, 365 days
- Original door: steel sliding, damaged and poorly sealed
- Replacement: TSS1020 high-speed sliding door
Result:
Annual electricity savings of 67,733.14 kWh (80% reduction).
Air exchange accounts for 82.5% of total energy loss—minimizing open time is the most effective solution.
