Welke oorzaken A / C Compressor Slugging?
Airconditioning (A / C) -compressoren comprimeren het koelmiddel door het volume te verminderen. De werking van de compressor kan leiden tot slugging, wat een compressor kan beschadigen of kan doen mislukken.
Definitie
De slugging van de airconditioning van een airconditioner verwijst naar koelvloeistof in de compressor. Deze overstroming vloeit vaak voort uit een oververhitte motor of overmatige spanning die door de compressor stroomt.
Oorzaken
Compressoren bevatten doorgaans een bedrijfscondensator of een apparaat dat de stroom wijzigt naar een of meerdere motorspoelen. Als de bedrijfscondensator uitvalt, trekt de motor overtollige stroom tijdens het starten, waardoor het overbelastingsrelais wordt geactiveerd of overbelast, het apparaat dat de motor beschermt tegen hoogspanning. Dit hoge voltage zorgt ervoor dat de motor niet kan werken terwijl het koelmiddel door de aircocompressor blijft stromen en het volloopt. Als het systeem is opgeladen met een onjuist koelmiddelniveau, veroorzaakt doordat de technicus de juiste elektrische lading verkeerd meet, kan er te veel koudemiddel door de compressor stromen, wat leidt tot wateroverlast.
het voorkomen
De slugging van een aircocompressor kan worden voorkomen door te zorgen voor de juiste berekening van de koelmiddelvulling. Het openen van de compressor en het inspecteren op defecte componenten, zoals een defecte bedrijfscondensator, en deze zo nodig vervangen kan helpen verstopping te voorkomen.
FAQ - 💬
❓ What causes AC compressor slugging?
👉 Slugging can result in broken valves, broken head gaskets, broken connecting rods, and other major compressor damage. Refrigerant-cooled semi-hermetic compressors will often draw liquid from the suction line through hot motor windings in the motor barrel, which will assist in vaporizing any liquid.
❓ How do I stop my compressor slugging when I start it?
👉 The single best device to protect the compressor from slugging and floodback is the suction line accumulator. Accumulators are most often found on low temperature systems, but all refrigeration systems can benefit from this relatively low-cost protective device.
❓ What causes flooding and slugging on a compressor?
👉 Flooding or slugging is usually the result of the compressor providing too much cooling capacity for the load in the space or not having enough heat content in the air to evaporate the liquid refrigerant. Compressors are a vapor pump that can't handle liquid refrigerant.
❓ What is liquid slugging in a compressor?
👉 Liquid slugging is the phenomenon of liquid entering the cylinder of a reciprocating compressor, a common cause of failure. Under normal conditions, the intake and output of a compressor cylinder is entirely vapor or gas, when a liquid accumulates at the suction port liquid slugging can occur.
❓ How do you prevent flooding and slugging?
👉 How do you prevent flooding and slugging? Keep superheat at proper levels.
❓ What are the signs of a failing compressor?
👉 Below are seven telltale signs of a failing AC compressor.
- You Hear a Ticking or Chattering Noise. ...
- You Hear a Rattling or Rumbling Noise. ...
- There Is Less Air Flow. ...
- Warmer Air Is Flowing Out. ...
- The Refrigerant Is Leaking. ...
- The Circuit Breaker Keeps Tripping. ...
- The Unit Vibrates When It Starts Up.
❓ How do I stop my compressor from flooding?
👉 By moving all of the system's refrigerant to the “high side,” and the oil being most commonly found in the compressor shell or body is then separated from the refrigerant and contained in the “low-side.” By keeping both the oil and refrigerant from being in contact with each other, the possibility of a flooded start is ...
❓ What is the difference between slugging and flooding?
👉 What is the difference between flooding and slugging? Flooding is a little liquid refrigerant reaching the compressor; slugging is a lot of liquid refrigerant reaching the compressor all at once.
❓ What is slugging in air conditioner?
👉 Essentially, slugging is the result of trying to compress liquid refrigerant and/or oil, in the cylinders. Slugging indicates extreme floodback in air-cooled compressors and severe flooded start on refrigerant-cooled compressors.
❓ What is the most common cause of compressor failure?
👉 AUTOPSY OF A COMPRESSOR: The two most common causes of compressor failure are loss of lubrication and slugging, according to Brainerd Compressor Inc.
❓ How long should an AC compressor last?
👉 about 12-15 yearsThe short answer is that your AC compressor and refrigerant should last about 12-15 years. Learning what crucial components, and how to maintain the compressor, can keep your AC running efficiently for its entire lifespan.
❓ What happens if you slug a compressor?
👉 Slugging. These oil and refrigerant droplets can now get past piston rings and other small openings and enter the compressor’s cylinder. The end result is slugging of refrigerant and oil. Slugging can damage valves, piston rods, bearings, and many more mechanical parts.
❓ What is liquid slugging and what causes it?
👉 Some of this liquid will then find its way into the compressor and hence causing liquid slugging problems. Liquid slugging is a serious condition that not only reduces the efficiency of an air conditioning system, but also leads to extensive compressor damage.
❓ What are the symptoms of a bad centerball on a compressor?
👉 • Defective centerball or gear mating surface. • Liquid slugging due to improper system charging. •Charging liquid refrigerant into compressor (washes off oil film from around the centerball when the compressor is connected). A/C malfunctions explained 1 ABOUT SANDEN A/C SYSTEM OVERVIEW2
❓ Can a compressor damage my a/C system?
👉 Compressors are susceptible to damage whenever failures occur within the A/C system. System fail- safes such as Pressure Relief Valves (PRV), Thermal Protection Switches (TPS) and High / Low pressure cut offs are often used to reduce the possibility of compressor damage under abnormal system conditions.
