![]() In this article, we answered some of the most frequently asked questions about scroll compressors and learned about a scroll compressor's components and operation principles. In the case of an LG Gen 3 Scroll compressor, various protection components such as a thermal protector, and internal pressure relief valve prevent the compressor from overheating and malfunctioning. Scroll compressors have excellent motor performance, reduced friction, and high cooling and heating performance. What are the advantages of a scroll compressor?Īs we learned above, a scroll compressor has fewer moving parts meaning lesser wear and tear on the system making them more durable and reliable. The SPR scroll compressors are exceptionally quiet thanks to the slow speed of the scroll. LG Gen 3 Scroll Compressor is also equipped with various protection components for stable, reliable operation such as a thermal protector, internal pressure relief valve, discharge check valve, and overload protector. Scroll compressors are known to be more efficient which translates to higher cooling efficiency than a standard reciprocating compressor. The oil-free scroll compressors are easy to operate and maintain. In short, a scroll compressor has fewer parts than a piston compressor also commonly known as the reciprocating compressor.ĭue to fewer moving parts, a scroll compressor has a smoother and quieter operation compared to a piston compressor. What is the difference between a scroll and a piston compressor?Ī scroll compressor only requires two scrolls to compress the refrigerant, whereas, a piston compressor uses two or more cylinders and multiple valves for compression. Are R407C compressor possible to use with others refrigerant The compressors. The refrigerant compressed in this way is discharged through the top and flows back into the system. That is way PANASONIC cant give the approval to R290 for scroll compressor. The refrigerant moves along the spiral shape inside the wrap in a circular motion, increasing its temperature and pressure. The fixed scroll (on the upper side) and the orbiting scroll (on the lower side) are interlocked and as the motor runs the scroll wrap moves in the form of a rotating curve to compress the refrigerant flowing into the space inside the wrap. The lower orbiting scroll combined with the motor’s shaft receives power from the motor. Scroll compressors also have safety components such as a thermal protector, internal pressure relief valve, discharge check valve, and overload protector to protect the compressor from damage. Scroll compressors are usually rated in HP (horsepower) where 1 HP is equivalent to about 0.75 RT (refrigeration tonnage) or 9000 BTU. The maximum capacity of a scroll compressor is often capped at 30 HP. These two can further be divided into smaller subcomponents such as – scroll wrap, fixed scroll, orbiting scroll, motor, bypass valves, etc. Generally, a scroll compressor can be identified by its black color or blue color and cylindrical-shaped body. The mechanical section is where the compression takes place and the electrical section, which consists of a motor, is responsible for providing electrical energy to the compression chamber. It consists of two scrolls: a fixed scroll and an orbiting scroll, which are responsible for compressing the refrigerant.Ī scroll compressor consists of two main sections: mechanical and electrical section. And one of the most widely used compressors in these systems is a scroll compressor.Ī scroll compressor is a positive-displacement compressor that uses scrolls for compressing the refrigerant. The most common examples would be an air conditioner and a refrigerator. Compressors are some of the most important mechanical devices used for both: heating and cooling systems. ![]() Sources , , hitachi-ap.We are surrounded by compressors in our everyday lives, even if we do not realize it. – The compressed air gets very hot! Much hotter than compared to other types of compressors – When the compressor-element fails, there’s a very big chance you just have to buy a whole new element. – Low capacity (flow, liters/minute or cfpm). As the gas moves into the increasingly smaller inner pockets, the temperature and pressure increase to the desired discharge pressure. On the outer portion of the scrolls, the pockets draw in gas, and then move into the center of the scroll, where the gas is discharged. The orbiting motion creates a series of gas pockets traveling between the two scrolls. ![]() ![]() The orbiting scroll is coupled to the crankshaft and orbits, rather than rotates. In rolling stocks, scroll compressor is used for HVAC and brake systems. A scroll compressor (also called spiral compressor, scroll pump and scroll vacuum pump) is a device for compressing air or refrigerant. ![]()
