What Makes Up a Cold Storage Room?
As illustrated, a standard cold storage room generally consists of the following six core systems:
1. PU Panels
Cold‑storage panels consist of floor, wall and ceiling panels. For floor panels, either XPS boards or embossed aluminum steel sheets are available as options.
We select appropriate panel thickness according to the operating temperature of the cold room:
0°C storage: 100 mm thickness recommended
-18°C freezer: 150 mm thickness recommended
-30°C blast freezer: 200 mm thickness recommended
2. Cold storage Door
We offer a full range of insulated cold storage doors, including manual and electric sliding doors, fully recessed and semi-recessed doors, overhead doors, and PVC impact-resistant doors.
These doors are designed to accommodate various cold storage sizes, traffic frequencies, and operating conditions, and are also suitable for buffer zones between production areas and cold storage facilities. All electric cold storage doors are built with high-quality core components, ensuring stable long-term operation and excellent overall cost performance.
3. Temperature Controller
Our intelligent cold‑storage electric control cabinet comes with an automatic defrost function to eliminate manual defrost work and keep your cold room running stably. With WiFi connectivity, it supports remote mobile phone operation. You can check real‑time temperature, start‑stop equipment and receive fault alerts remotely, enabling convenient off‑site monitoring and reducing on‑site maintenance costs.
4. Condensing Unit
This air‑cooled condensing unit consists of compressor, condenser coil, fan, receiver, oil separator, high‑low pressure switch, accumulator, vibration absorber and outer shell.
Compressor: Semi‑hermetic reciprocating compressor, energy‑saving and eco‑friendly, delivering required cooling capacity with low energy consumption.
Condenser Coil: Copper tubes with sine‑wave fins enhance heat transfer, create strong air turbulence for optimal heat exchange performance.
Fan: High‑efficiency & low‑noise detachable fans for easy maintenance. IP54‑rated motors are fully tested and balanced before delivery.
Receiver: Horizontal or vertical types available. Safety components comply with ASME standards, rated for 45 bar pressure. Capacity is customized for project requirements.
Oil Separator: Advanced separation‑filtration technology prevents oil from entering downstream pipelines, ensures reliable compressor lubrication and improves overall system performance.
Accumulator: Subcools liquid refrigerant by low‑temperature return gas to avoid compressor liquid slugging. It also filters impurities from evaporator return gas.
High and Low Pressure Switch: Offers protection against abnormal suction / discharge pressure, controlling start‑stop of compressors and fans.
Vibration Absorber: Corrugated flexible hose absorbs vibration and prevents compressor vibration from spreading through piping.
Outer Shell: Made of aluminum‑magnesium alloy, featuring good corrosion resistance, attractive appearance and durable construction.
All components work together to ensure safe, stable and efficient operation of cold‑storage refrigeration systems.
5. Evaporator
Electric heating tube heat transfer device shortens defrosting time. Adopting advanced liquid distribution technology and aerodynamic design. Side panels and water drain pan are of detachable structure. Combined threaded tubes and corrugated fins deliver excellent heat‑exchange performance.
6. Air Curtain
The air curtain forms an air barrier at the doorway. It blocks external hot and humid air intrusion, reduces cold loss and frost, ideal for frequent loading and unloading scenarios.
