This guide covers small cold rooms (under 100m³, typically 5–50㎡): how to choose, costs, equipment configuration, shelving options, and reliable installers nationwide. Use it as a practical reference.
1. What is a small cold room? (Applicable scenarios)
In the industry, it generally refers to: volume < 100m³, area 5–50㎡, ceiling height 2.5–3.5m.
- Cold storage (fresh): 0–5°C (fruits, vegetables, flowers, dairy products)
- Freezer storage: -18 to -25°C (frozen meat, seafood, quick-frozen foods)
- Dual-temperature room: one section for fresh storage, one for freezing (commonly used in restaurants/fresh food stores)
- Pharmaceutical room: 2–8°C (GSP, for pharmacies/clinics)

3. Core Configuration (Must-read to avoid pitfalls)
1) Insulated panels (most critical)
- Cold storage (fresh): 100mm polyurethane (PU) panels
- Freezer storage: 150mm PU panels (no condensation at -25°C)

- Type: fully hermetic scroll (first choice for small cold rooms, quiet, energy-saving)
- Cooling: air-cooled (simple installation, no cooling water required)
3) Evaporator (cooling fan)
- Cold storage (fresh): DD series
- Freezer storage: DJ series (with defrost heating elements)
- Controls: fully automatic temperature control + timed defrost + temperature display
4) Floor treatment (often overlooked)
- Cold storage (fresh): polyurethane insulation layer + waterproof membrane + cement mortar
