What Is the Appropriate Amount of Refrigerant for Scroll Chillers?

Jul. 14, 2021

Industrial scroll chillers according to the form of refrigeration can be divided into water-cooled scroll chillers and air-cooled scroll chillers two. Do you know the two types of refrigeration?

If the industrial scroll chiller is used for more than six months, or if the high and low pressure engines frequently fail, or if the cooling capacity decreases, please arrange staff to clean the radiator. Refrigerant, as we all know, is an indispensable material for industrial chillers, so do you know how much refrigerant refill is appropriate for scroll chillers in the process of use? Next, the chiller supplier will share the following content with you.

 

Industrial scroll chillers in the use of timed refill machine to refill refrigerant, only at the end of time, take time to close the valve of the timed refill machine, open the liquid filling valve and refill the refrigerant to the refrigeration system.

The refrigerant charge of rolling chiller is general, not charge nor more charge less, small industrial rolling chiller device uses quantitative filling machine to charge refrigerant, only after the three-way valve in the refrigerating plant closes a good vacuum, stop the vacuum pump, remove the vacuum pump and pressure hose joint, between the quantitative filling machine of liquid production, open the liquid valve to discharge the air in the hose, then tighten the hose connection and check whether there is leakage.

 

Industrial scroll chiller is filled with refrigerant, first observe the filling pressure gauge reading on the scale rotating sleeve, find the quantitative liquid line on the sleeve corresponding to the pressure gauge, and write down the initial liquid level calibration value of refrigerant in the glass tube. Then open the three-way valve, the refrigerant enters the refrigeration system through the pipeline, and the liquid level of refrigerant in the glass tube starts to fall. When the charge amount is reached, the solution between the liquid and the charge triple closes.

 

Do you want to know how to save energy in industrial scroll chillers?

Industrial rolling chillers can increase the evaporation temperature and lower the condensation temperature by lowering the condensing temperature to meet the safety and production requirements of the equipment. Under the condition of ensuring the safe operation of the equipment, adjust the temperature rolling chiller reasonable operating load, the refrigeration mainframe operating at 70% 80% load than at 100% load, the cold unit electricity consumption is smaller. The operation of water pumps and cooling towers should be considered in this way.

Why choose air cooled scroll chiller

The series modular air cooled scroll chiller cooling capacity from 7KW to 120KW. This series units integrates the characteristics of many other products, using imported full-closed scroll compressors, supplemented by high-efficiency heat exchangers and adopts microcomputer controllers, which makes the unit compact, reasonable layout, convenient to use and maintain. The user just need simply connect the pipeline of the water system and the required power supply,then can put into operation.

 

This series of chillers is widely used: it can provide process chilled water for industrial and mining enterprises such as textile, chemical and petroleum. The manufacturing technology of this product is mature and stable and reliable. Welcome to contact us today or request a quote.
