Abstract

The invention relates to the technical field of centrifugal chillers, in particular to a double-machine head centrifugal chiller system. The double-machine head centrifugal chiller system comprises a first centrifugal compressor intake valve (1), a second centrifugal compressor intake valve (2), a first centrifugal compressor exhaust valve (3), a second centrifugal compressor exhaust valve (4), a first centrifugal compressor gulp valve (5), a second centrifugal compressor gulp valve (6), a first bypass valve (7), a second bypass valve (8), a first throttle valve (9), a second throttle valve (10), a first centrifugal compressor (11), a second centrifugal compressor (12), a first evaporator (13), a second evaporator (14), a first condenser (15), a second condenser (16), a first power saver (17), a second power saver (18), a first centrifugal compressor intake pipe (19) and a second centrifugal compressor intake pipe (20). The system is simple in design, easy to operate, stable, reliable and easy to be installed, cleaned and maintained.

Description

technical field [0001] The invention relates to the technical field of a centrifugal chiller, in particular to a double-head centrifugal chiller system. Background technique [0002] At present, nuclear power plants, petrochemicals, pharmaceuticals, food refrigeration and other industries at home and abroad generally use centrifugal chillers to achieve process and environmental control. As the most important equipment in chillers, centrifugal refrigeration compressors play an important role in the efficient and reliable operation of the chillers. Crucial role. In related fields with large cooling capacity consumption, the cooling demand is usually realized in the form of a double-head centrifugal chiller. In the current conventional dual-head centrifugal chiller system, only a single centrifugal compressor needs to be turned on in winter or when the end load of the user is relatively small. In the working condition of a single centrifugal compressor in the double-head cent...
