Walk in Cooler and Reach-in-Cabinet
WALK-IN COOLER
- Large refrigerated storage unit used in restaurants, supermarkets, and food industries.
- Maintains temperatures between 0°C to 5°C for perishable goods.
- Main Components & Their Functioning
| Component | Function |
|---|---|
| Compressor | Pressurizes refrigerant and circulates it. |
| Condenser Coil & Fan | Removes heat from refrigerant. |
| Expansion Valve | Controls refrigerant flow into evaporator. |
| Evaporator Coil & Fan | Absorbs heat, cooling the interior space. |
| Thermostat | Maintains set temperature. |
| Insulated Panels | Reduces heat loss. |
| Defrost System | Prevents ice buildup on evaporator. |
- Working Principle
-
- Compressor compresses low-pressure refrigerant into a high-pressure gas.
- The condenser coil dissipates heat, turning refrigerant into liquid.
- Expansion valve reduces pressure, cooling the refrigerant.
- Evaporator coil absorbs heat, cooling the interior.
- Thermostat cycles the system on/off as needed.
- Capacity & Types
- Small Walk-in Cooler – ~1 to 5 HP (Horsepower)
- Medium Walk-in Cooler – ~5 to 15 HP
- Large Walk-in Freezer – Above 15 HP
- Care & Maintenance
- ✅ Clean condenser coils for efficient cooling.
✅ Check door seals to prevent warm air leakage.
✅ Monitor refrigerant levels for proper cooling.
✅ Defrost regularly to avoid ice buildup.
- ✅ Clean condenser coils for efficient cooling.
