Installation Of Evaporative Condenser In Cold Storage

Evaporative condenser is a commonly used heat exchange equippment for cooling cold storage. Generally installed on the top of the machine room, the roof structure of the machine room needs special treatment, and it is required to bear the weight of the evaporative condenser.

The cold storage evaporative condenser installation must be firm and reliable and well ventilated. The top of the installation should be 300mm higher than the adjacent building, or at least not lower than the height of the adjacent building, so as to avoid the return of hot and humid air along the wall to the air inlet; If the above requirements cannot be met, a tapered air duct should be installed on the air outlet at the top of the evaporative condenser during installation to increase the outlet wind speed and exhaust height and reduce backflow.

Cold storage evaporative condenser installation also has a single table and multiple parallel installation types. When installing, pay attention to the distance from the neighboring buildings, generally pay attention to the following conditions:

1. When the evaporative condenser is walled on all sides, the minimum spacing on the air inlet side during installation should be 1800 mm, and the minimum spacing on the non-air inlet side is 900 mm.
2. When the evaporative condenser is a solid wall on three sides and an empty wall on the side, the minimum spacing on the air inlet side should be 900 mm, and the minimum spacing on the non-air inlet side should be 600 mm.
3. When two evaporative condensers are installed in parallel, if both are on the air inlet side, the minimum distance between them should be 800mm; if-one is on the air inlet side and the other is on the non-air inlet side, The minimum spacing is 900mm; if both are not on the air inlet side, the minimum spacing is 600mm.

When the evaporative condenser uses a coaxially connected centrifugal fan or a water tray with an electric heater, in the above 2 and 3 cases, the minimum spacing should be increased to facilitate maintenance.

After ensuring the distance between the evaporative condenser and the adjacent building, pay attention to the water tray of the evaporative condenser should not be less than 500mm from the ground during installation, in order to facilitate pipeline connection, water tray leak detection and prevent ground dirt from being Fan suction.

During the matching installation of the evaporative condenser in the cold storage, the liquid inlet pipe of the evaporative condenser and the liquid reservoir of the single group cooling pipe can be used for pressure equalization. The slope of the horizontal pipe section is 1/50. To the reservoir. If the installation position of the valve is limited by the construction conditions, it can be installed on the main pipe, but it must be installed below the liquid outlet 200mm.
