With a valve plate/head replacement, the addition of the solenoid coil, discharge temperature sensor and controller, a discus compressor can be converted to a digital discus. The digital scroll compressor modulates output by separating the scrolls on a duty cycle, essentially a mechanical way of turning the compressor on/off as necessary while keeping the motor running. During the loaded state the compressor operates like a standard scroll compressor and delivers full capacity and mass flow. The Copeland new Digital scroll compressor delivers precise operation & significantly higher energy efficiency. The scroll air compressor, which is a displacement type rotating machinery, uses the scroll rotor to mesh with the scroll stator to form a plurality of compression chambers. Comme son nom l'indique c'est un compresseur de type scroll qui est donc composé de deux spirales, une spirale fixe et une spirale qui orbite autour de la première entraînée par un moteur électrique.La vitesse du compresseur étend toujours nominale ce qui permet d'adapter la puissance développée par le compresseur en réponse à la demande est possible grâce à l'utilisation d'une vanne solénoïde raccorder entre l'aspiration et la partie supérieure du compresseur.Celle-ci une fois alimentée permettra la communication de la haute pression avec la chambre de modulation. There are 2 factors that make the oil return easy. View Product .

There are two basic types of rotary screw compressors: oil-injected and oil-free. T Copeland Compressors (now a Division of Emerson) has recently introduced their digital scroll compressor technology. Fewer parts make the scroll compressor energy efficient, highly reliable, and less prone to mechanical failure. A digital scroll compressor is a device designed to compress air or refrigerant. You must be a magazine subscriber to access this feature. The Copeland Scroll Digital TM compressor improves on the basic scroll design by having axial and radial compliance, which allows the fixed scroll to move in both the axial and radial directions Scroll compressors provide a very smooth compression process and have fewer moving parts compared with traditional reciprocating compressors. A wide variety of digital copeland scroll compressor options are available to you, such as refrigeration compressor, condenser. A scroll compressor (also called spiral compressor, scroll pump and scroll vacuum pump) is a device for compressing air or refrigerant. Bien entendu quand la vanne solénoïde n'est plus alimentée la spirale fixe redescend en position normale et la compression peut reprendre, le compresseur fonctionne à pleine charge.Ce type de compresseur offre une grande plage capacité de puissance allant de 10 à 100 %, pour obtenir cette puissance variable la modulation est obtenue par unité de temps par cycle. The scroll compressor is another popular type of compressor. For more than 80 years, we have been introducing innovative technology to the market, from the first semi-hermetic and hermetic compressors in the 1940s and 1950s, the high efficiency DiscusTM semi-hermetic, air conditioning and heating scroll compressors in the 1980s and 1990s, to the new Stream semi-hermetic and the digital scroll compressor technology of today. Reliability is a major concern in most refrigeration applications. Does anyone here have experience with comparing the two technologies? Scroll compressors run quieter and smoother than reciprocating compressors because they only have two moving parts: a fixed and orbital scroll. The pumping output of a digital compressor operates in two stages - "loaded" and "unloaded". They started being made just after WWII, and started being commercially produced in large volumes beginning the in 80’s, as refrigeration compressors. The oil-injected type is most common, because it has a much lower price-tag than the oil-free one (which you should only use if your application requires 100% oil-free air).
