Connection principle and sewage treatment requirements of the R717 ammonia evaporative condenser
Dec 17, 2018

The R717 ammonia evaporative condenser should be effectively installed on the top of the building or on the flat support during the operation. The air outlet of the unit axial fan must be higher than or at least equal to the top of the circumferential wall to avoid dehumidifier gas reflux. The piping layout shall comply with the requirements of the refrigeration cycle piping installation specification. A balance pipe shall be installed between the condenser and the high pressure reservoir to prevent other clogging and return the working fluid to the condenser.

Connection principle of the R717 ammonia evaporative condenser

1. The pressure equalization pipe between the accumulator and the condenser should be connected at the inlet of the condenser. The function of the liquid trap at the outlet pipe is to establish a certain liquid seal to offset the outlet pressure between the condenser tubes. difference.

2. R717 ammonia evaporative condenser will be left in the water tank due to the evaporation of spray water, and the impurities and other impurities contained in the water will be left in the water tank. It should be discharged regularly to prevent the accumulation of the above substances, otherwise the acidity or mineral content of the water Will increase, causing corrosion and scale.

3. R717 ammonia evaporative condenser uses chemical to treat scale. The chemical must not affect the quality of galvanizing on the surface of the unit. The PH value of circulating water should be kept between 6.5 and 8.0. When the pH exceeds 8.3, it should be cleaned. Special attention should be paid when acid-resistant treatment is required, and only mild corrosion is recommended for galvanizing. Solutions for water treatment should be requested by an experienced water treatment company.
