Glen refrigeration offers different types of walk in cooler refrigeration unit for commercial cold rooms, including wall mount refrigeration unit, top mount refrigeration unit, split system refrigeration unit.
The walk in cooler refrigeration unit working principle includes compression, condensation, expansion and evaporation, they are four major steps of the refrigeration system cycle.
The refrigeration compressor in walk in cooler unit sucks the low-temperature and low-pressure refrigerant from the evaporator, compresses it into high-temperature and high-pressure hot gas. The compressor is the heart of the refrigeration system cycle.
The high-temperature and high-pressure hot gas from the compressor flows into the condenser. The condenser fans blow air over the condenser coil to take away the heat. (If it is water-cooled condenser, the water takes away the heat outside). The high-temperature and high-pressure hot gas cools down and turns into high-pressure liquid refrigerant.
The expansion valve or capillary acts as a throttling device in the walk in cooler refrigeration system. When the liquid refrigerant passes through the expansion valve or capillary. The valve narrows the flow to drop the refrigerant pressure and temperature, the liquid refrigerant turns into liquid-gas mixture refrigerant.
Evaporation is the last step of refrigeration system cycle. The liquid-gas mixture refrigerant from the expansion valve enters the evaporator coil inside the walk-in cooler. It absorbs heat from the storage room and evaporates into gas. The evaporator fan blow the cold air to lower the storage temperature.
Glen Refrigeration offers different types of walk in cooler refrigeration units, including the wall mounted monoblock refrigeration unit, ceiling mounted monoblock refrigeration unit, split walk in cooler refrigeration units. The split walk in cooler refrigeration units includes the split condensing unit and evaporator unit. The split condensing units includes Sanyo outdoor condensing unit, Panasonic outdoor condensing unit, Copeland outdoor condensing unit, Inverter condensing unit and so on. Glen refrigeration aim to provide different walk in cooler refrigeration solutions to meet customer’s different requirements.
The wall mount refrigeration unit is a all in one refrigeration unit, integrated the walk in cooler compressor, condenser, expansion valve, evaporator and other refrigeration components into a packaged refrigeration unit. They are installed on the wall panel of the walk-in cooler, like a walk in cooler with window unit. Glen refrigeration offers wall mount refrigeration unit for small walk in cooler below:
They have the advantages:
They are best for self contained walk in cooler for hotel, restaurants, small grocery stores, convenience stores. If you need more details of the wall mount walk in cooler refrigeration unit, please visit: Wall Mount Refrigeration Unit
The ceiling mount refrigeration unit is a drop in refrigeration unit, the difference from the wall mount refrigeration unit is the installation place. The wall mounted refrigeration unit is installed on the wall panel of walk in cooler, but the ceiling mount refrigeration unit is installed on the roof panel of the walk-in cooler. The ceiling-mounted refrigeration unit installed at the top of a walk-in cooler saves more space for walk in cooler storage. Glen refrigeration offers 1HP, 2HP, 3HP ceiling mount refrigeration unit for small walk-in coolers.
They have the advantages:
If there is not enough space for wall mounted refrigeration unit, ceiling mounted refrigeration unit is a better solution for self contained walk in cooler for hotel, restaurants, small grocery stores, convenience stores. If you need more details of the wall mount walk in cooler refrigeration unit, please visit: Ceiling Mount Monoblock Refrigeration Unit
The split walk in cooler cooling system includes walk in cooler condenser unit and walk in cooler evaporator unit. Different from the monoblock refrigeration unit, the split refrigeration units for walk ins need to be connected on site. The walk in cooler refrigeration unit includes condensing unit and evaporator unit. The condenser unit is also called outdoor condensing unit, installed outside of the walk-in cooler. The walk in cooler evaporator unit is called indoor unit, installed inside of the walk-in cooler. They are connected by copper tube welding into a split refrigeration system for walk in cooler.
Glen Refrigeration offers Sanyo walk in cooler condensing unit from 1HP to 3 HP, Panasonic walk in cooler condensing unit from 4HP to 12.5 HP, Copeland walk in cooler condensing unit from 2HP to 30 HP and Walk in cooler evaporator unit.

Different flowers, the cold room storage temperature will have difference. The normal flower cold room storage temperature is +1° C to +5° C, RH90%~95%. For tropical flowers, the flower cold room storage temperature is 8° C to +12° C, RH80%~90%.
The key design of the flower cold room is the evaporator. The evaporator unit for the flower walk in cooler is different from normal cold storage evaporators. The flower cold room evaporator should be designed in low soft air circulation to prevent cold wind from blowing directly on flowers. Generally, the slim type evaporator or dual discharge evaporator are the best for flower cold rooms.
The split condensing unit and the slim type evaporator or dual discharge evaporator with low soft air circulation are recommended to flower cold rooms.
