Many dry climate warehouses and industrial plants, such as the Southwestern United States, use portableevaporative cooler instead of mechanical air conditioning because evaporative refrigerators are cheaper to operate. Engineers for commercial or industrial facilities that rely on evaporative refrigerators know that the units are simple and reliable, but like any mechanical device, they occasionally need maintenance and service.
Begin solving your problem by verifying the correct installation of the unit. For channels with ducts that have variable pulleys (motor pulleys), make sure that the pulley settings are set to the motor control panel amplifiers. Make sure the exhaust channel is available when setting the engine amplifiers; There should be about 2 square meters of exhaust for every 1,000 km / h of airflow produced by the cooling.
The coolant float water supply line should be ¼ inch copper pipe, and this line should be secured. Insecure water lines can configure the water hammer from the refrigerator to the shut-off valve. Portable evaporative cooler should be connected to a dedicated power supply line with appropriate fuses.
To block ditches during a winter shutdown, a canal bridge with a removable damper between the bucket and roof must be installed.
If aportable evaporative coolerblower appears to be operating outside the round (usually characterized by noise and vibration), check the eccentric collar attached to the inner stem collar. If the eccentric collar is not attached or loose, reconnect it to the inner stem collar by turning the eccentric collar toward the airflow and then tightening the setting screw.
Steps to Troubleshoot Portable Evaporative Cooler:
- Slide the unusual neckline over the pole. The neckline cut ought to be towards the finish of the bar (Fig. A).
- Slide the bearing assembly to the rod (Fig. B).
- Determine the final position of the bearing assembly. This is determined by how much shaft is required to mount the fan pulley.
- Screw the bearing assembly to the bearing support shaft. At this point, simply fasten your finger as it will need to be loose to allow shaft adjustment (Figure C).
- Rehash the initial three stages for the opposite side of the blower get together.
- Slide the unusual neckline to the inward race of the bearing get together. Pivot the neckline toward the blower revolution and ensure that there is no hole between the neckline and the bearing get together (Photos D and E).
- Determine the correct direction of the fan wheel for downward or sideways pull to the left or right of the fan housing.
- Use the collar screw, and tighten the eccentric collar screws using a 126 to 164-inch torque wrench.
- Finish tightening the bearing assembly to the bearing support rod.
- Tighten the collar and bearings on the other side of the fan housing.
- Center the fan wheel and tighten the wrench.
When adjusting the drive motor to the remote-control board amplifiers, make sure there is a proper relief (2 square feet per 1,000 cm). If the motor starts and stops, check the pulley adjustment.
If the drive motor cannot match the remote-control board amplifiers, determine if the correct pulley has been purchased for application. Note that some applications require minute turns defined by specific static pressures. Higher revolutions per minute in some static pressures when the motor is set to the clock amplifiers will cause water to penetrate.
When the size of the cooler application is unknown and the external static pressure (for example, it was not provided by the design engineer), the application must be increased for zero static pressure. Use revolutions per minute to static zero based on the technical information provided by the manufacturer and determine which pulley will operate at the same rpm.
The buoyancy supply line must be secured or it will cause a water hammer. If the water drains overhead, adjust the buoyancy. Leave space just below the height of the standpipe so that when the pump is shut off, there is enough room for water to come out of the medium.
Check if the lower tin tray needs repainting. Clear any residue or loose coating from the mold. A little polishing may be necessary. Expect the mold with elastic polyurethane sealant.
Check poplar or rigid media frequently. If the media areas are saturated with calcium deposits and there are areas in the same cushion frame or non-saturated wet array, unsaturated areas will cause water infiltration because the air velocity is higher in that area.
To limit calcium development in the media, utilize a channel hose that permits a portion of the reused water to deplete from the cooler. If the water utilization is an issue, buy a channel siphon outfitted with an inherent clock that permits the siphon to empty water out of the store like clockwork of siphon activity, or more you can visit top10bestoday.com for further information.
