What is the cooling chiller cleaning method?

Stop the machine and confirm that the pressure has been released, and pull down the main power switch. Open the air guide cover to clean the cover plate or remove the cooling fan.

Blow the dirt down with compressed air, and then take the dirt out of the air guide cover. If it is dirty, spray some oil remover before blowing; When the above methods cannot be used for cleaning, it is necessary to remove the FL-800N -18°C ~ +30°C Small Water Chiller, soak or spray it with cleaning solution and use a brush. It is strictly prohibited to use a wire brush) for cleaning. Install the cover plate or cooling fan.

1. What are the cleaning techniques of the cooler?

The hot fluid of the air cooler flows in the tube, and the air blows through the tube bundle. As the ventilation volume required for heat exchange is large and the air pressure is not high, axial flow fans are often used (see fluid conveying machinery).

The type and material of tube bundle have a great influence on the performance of air cooler. Since the heat transfer coefficient at the cooler side is very small, fins are often added to the tubes to increase the heat transfer area and fluid turbulence and reduce the thermal resistance.

Most cooling water contains calcium, magnesium ions and acid carbonate. Carbonate is formed when the cooling water flows over the metal surface. In addition, the oxygen dissolved in the cooling water will cause metal corrosion and rust.

The heat transfer performance of the condenser decreases due to the generation of rust. In case of serious scaling, cooling water can only be sprayed outside the shell. In case of serious scaling, the pipe will be blocked, making the heat exchange ineffective.

The research data shows that the scale deposit has a great impact on the heat transfer loss, and the energy cost will increase with the increase of the deposit. Even a thin layer of scale will increase the operating cost of the scaling part of the equipment by more than 40%. Keeping the cooling channel free of mineral deposits can save energy, increase the service life of equipment, and save production time and cost.

2. What are the precautions for the use of industrial chillers?

First, place the chiller in a cool and ventilated place for use. The operating ambient temperature of the chiller should not be too high, and the operating ambient temperature of the chiller should not exceed 40 ℃.

Secondly, the fan of the chiller has the heat dissipation function. Regularly check the operation of the fan, dismantle and wash the dust screen of the chiller, and clean the dust and sundries on the dust screen with an air gun.
