Process Chiller Buyer S Guide Hot Gas Bypass Youtube Hello friends! in this video, i will provide information about chiller surge.chiller surge refers to a phenomenon or mechanical issue that occurs in the fiel. It’s maximum lift is from 300 kpa to 900 kpa. (3 bar to 9 bar). that means it will take refrigerant in from the evaporator at a pressure of 300 kpa (3 bar) and it will compress it and force it into the condenser to it’s maximum which is 900 kpa (8 bar). the chiller can therefore provide 600 kpa (6 bar) of lift. (900 kpa – 300 kpa). Chiller surge is inevitable if the chillers can’t handle the low load conditions. hence, it is a good idea to consider using small centrifugal chillers to cater to the initial low load conditions to prevent chiller surge. 2. high ambient wet bulb temperature. chiller surge may occur when the ambient wet bulb temperature is higher than expected. Centrifigul compressor surging is a condition where the existing head (lift) exceeds the compressors pumping head (lift). most centrifugal refrigeration compressors have (develop) a lift of about 70*f. for example: sst = 35*f and sct = 105*f so the diff = 70*f. if say the sct goes to 110*f and the sst stays at 35*f then the lift = 75*f and you.

Vane guides sit directly in the flow path of the refrigerant and can be controlled to change their position. the chiller produces chilled water by removing the thermal energy, from the “chilled water loop” within the evaporator, which was picked up from the building. the amount of cooling generated needs to vary to match the load, otherwise. Hot gas bypass is a means of recirculating hot discharge refrigerant back into the evaporator. the refrigerant must pass through a pressure reducing device (hot gas bypass valve). the purpose of hot gas bypass is to maintain a minimum gas volume flow rate through the compressor to avoid surging or stalling during low load conditions.
