Works ZB series of scroll compressor: a scroll compressor the pressure is due to the interaction of solar motion between the scroll generated. When one of the scrolls for planets outside the opening movement of gas from entering. Gas into the vortex after-hours, opening closed with scrolls continue for planetary motion, the gas is pressed into smaller and smaller spaces. When the gas reaches the center, reaches the discharge pressure, in fact, in operation, all six gas passages are in various stages of compression, suction and discharge process to ensure substantially continuous and uninterrupted. Simple concept vortex first invented in 1905. Scroll is an involute spiral, as shown above, and scroll to match the engagement, forming a series of gradually expanding the presence of the space in between the two parts. When the compressor, a scroll remains stationary (fixed scroll) and the other scroll (rotating scroll) is allowed a first disc planetary motion (but not rotating) the orbital. When this movement occurs when the space between the two discs are pushed slowly moved to the center of the two scrolls, while the volume is also reduced. When the space reaches the central scroll, at high pressure gas is discharged through a centrally located passage. In the compression process, several chambers are simultaneously compressed, forming a very smooth process. During inspiration (scroll outer portion) and the exhaust process (inner portion) are continuous. Copeland Scroll technology has revolutionized the pattern of HVAC and refrigeration markets, first in North America, home air conditioning market performance excellence, and then enter the global market, other applications, such as commercial air conditioning and refrigeration. Following Emerson Climate Technologies to bring Copeland Scroll technology into the Chinese market, and now China has become the largest of Emerson Climate Technologies business markets outside the United States. Emerson Climate Technologies in Suzhou, Xi'an, Shenyang and Shanghai have set up R & D centers and production lines, and will continue to increase its investment in China. Now, Copeland scroll compressor application is more diversified, is widely used in home air conditioning systems, residential and commercial heat pumps, geothermal heat pumps, commercial air-conditioning units and chillers machines, supermarkets and food service refrigeration systems, cold chain logistics, road / Railway air-conditioning, data center cooling units and numerous cooling applications.
