[Unstable Cold Storage Temperature, Meat Almost Melting? Don't Panic, Check These 3 Steps First!] Feeling colder than the meat when the cold storage temperature fluctuates? Don't worry, check these three points, and the problem might be solved quickly!
❄️ Step 1: Quick Check for "Common Causes"
Power Supply and Switches: Confirm a stable power connection and check if the equipment switches have been accidentally touched.
Condenser and Ev***rator: Check if the vents are blocked by frost, dust, or debris. Poor ventilation directly affects cooling.
Door Seal Sealing: After closing the door, use a flashlight to check for light leakage at the door seams. Aging, damaged, or icy seals will cause cold air to leak out.
🌡️ Step 2: Observe Temperature and Equipment Status
Temperature Settings: Confirm that the temperature setting on the control panel is correct and not mistakenly set to a high temperature.
Defrosting Functionality: Prolonged lack of defrosting or a malfunctioning defrost system can lead to excessive ice buildup, affecting cooling efficiency. Check if the defrosting system is operating as set.
Equipment Operating Sounds: Listen for abnormal noises or frequent starts and stops from the compressor and fan. This may indicate excessive equipment load or component failure.
🔧 Step 3: Simple Handling and Timely Assistance
Temporary Response: If the temperature has risen, easily perishable ingredients can be concentrated in the deeper part of the cold storage or temporarily stored in another low-temperature area.
Contact Professionals: If the above steps do not resolve the issue, please contact maintenance service immediately. Take photos or videos to record the abnormal equipment symptoms for quick diagnosis by a technician.
🌟 Prevention Tips: Clean the condenser and ev***rator regularly and ensure adequate ventilation.
Check door seals monthly and replace worn rubber strips promptly.
Avoid placing large quantities of uncooled food into the system at once to reduce equipment load.
Stable temperature is essential for maintaining quality! If you cannot resolve the issue yourself, be sure to contact a professional for repairs immediately to prevent further damage.

📢 Fruit and vegetable farmers must see! Choosing low-cost cold storage panels in this way saves money and is practical!
Worried about the difficulty of preserving fruits and vegetables? Is building a cold storage too expensive? Remember these points, easily handle them!
✅ Select thickness
• Store for 1-3 months (such as peaches, autumn apples): choose 100mm thick
• Store for more than six months (off-season dishes): choose 120-150mm thick
✅ Select materials
• Insulation core material: Polystyrene (EPS) for short-term storage, low price
Panel: Color steel plate is the most cost-effective, with sufficient rust prevention
✅ Money saving tips
Choose a splicing type, which can be disassembled and reused next year
Customize according to actual size needs, don't buy too big
Non planting season orders often offer discounts
💡 Small unit plan (storage capacity of several tons to over ten tons)
100mm thick EPS core material+color steel plate
• Temperature setting: 0-4 ℃ for leafy vegetables, 5-10 ℃ for fruits and vegetables
Approximately 10 square meters, with a cost of around 10000 to 20000 yuan
⚠️ Attention
Small cold storage can be installed by oneself, while large cold storage is recommended to seek professional installation
Carefully inspect the insulation layer of second-hand boards
After construction, install a thermometer and regularly defrost

🔥 The Difference Between Fire Resistance Grades B1/B2/B3 for Cold Storage Panels – A Complete Guide!
📌 Grade B1: Flame Retardant
Self-extinguishing, high safety
Suitable for food storage and high-standard warehouses
📌 Grade B2: Flammable
Ignitable, burns slowly
Suitable for general industrial environments
📌 Class B3: Flammable
Easily ignitable and burns rapidly
It is generally not recommended to use
💡 Selection Suggestion:
Check local fire safety regulations
Assess the risks of stored items
It is recommended to choose the B1 level for greater safety
Ensure fire safety equipment is provided

❄️ Cold storage summary frost? Maybe the library board was not selected correctly!
Defrosting is troublesome and consumes electricity? The problem may lie in the cold storage panel itself. When the insulation of the board is insufficient and the inner wall temperature is too low, it will continuously frost like the "condenser" in a refrigerator.
Three points for quick self inspection:
Is the thickness sufficient?
Freshness preservation warehouse (0~10 ℃) commonly used 100mm
Freezing warehouse (-18 ℃) application 150mm
Quick freezing warehouse (below -25 ℃) must be ≥ 200mm
The board is too thin, the insulation is poor, and the inner wall is prone to condensation and frosting.
2. Is the material correct?
Polyurethane board: good insulation, not easy to frost.
Polystyrene board: Weak insulation, high risk of frost formation at low temperatures and high humidity.
Use polystyrene board with caution in low temperature and humid environments.
Is the seal tight?
Check if the lock buckle is tight and if there are any cracks in the sealant.
A small gap is the entrance for water v***r and cold bridge.
What should I do?
Established database: Check the board and repair the gaps. If it is severe, replace the board.
New library: Select the appropriate thickness and material based on temperature (polyurethane is preferred), and ensure professional installation.
