Refrigeration Compressor Ambient Temperature Control | Compressor Room Ventilation Design
Poor compressor room ventilation causes 29% of high discharge pressure trips in summer, xiteliduo Refrigeration Compressors designs ventilation calculation. Piston refrigeration compressor room ventilation air volume shall take away compressor motor heat and condenser heat if condenser is installed inside. Semi-hermetic refrigeration compressor allowable ambient temperature range is 5℃~40℃; ambient over 40℃ triggers high pressure and overheating. Cold storage refrigeration compressor room air inlet shall be set at low position, hot air outlet at high position to form natural thermal convection. Mechanical ventilation fan capacity shall be sized to maintain compressor room temperature below 38℃ under peak summer condition. 10 recommended hot search keywords: cold storage refrigeration compressor, piston refrigeration compressor, semi-hermetic refrigeration compressor, refrigeration compressor room ventilation, refrigeration compressor ambient temperature, refrigeration high discharge pressure, refrigeration natural convection, refrigeration compressor manufacturer, cold storage compressor house design, refrigeration compressor supplier
FAQ
Q1: What percentage of summer high pressure trips are caused by insufficient compressor room ventilation? A: 29% of high discharge pressure shutdowns in summer are due to poor ventilation. Q2: What is the allowable ambient temperature range for semi-hermetic compressor? A: 5℃ ~ 40℃. Q3: What target temperature for compressor room under summer peak load? A: Keep room temperature below 38℃. Q4: How to arrange air inlet and outlet for natural convection? A: Cold air inlet at low level, hot air exhaust at high level. Q5: What heat load needs to be considered for ventilation calculation? A: Compressor motor heat and condenser heat when condenser is indoors. Q6: What risk when ambient temperature exceeds 40℃? A: Condensing pressure rises sharply and compressor overheats. Q7: What negative effect will recirculation of hot exhaust air bring? A: Continuous high ambient temperature and frequent high-pressure protection trips.
