17 Sep 2015 In exemplary embodiments, a centrifugal compressor equipped with a variable frequency drive and variable inlet guide vanes may be utilized. . The method according to claim 9, wherein intermediate capacity range is defined in part by an inflection point of a compressor surge control boundary. 14.
CAGI: For starters, you can save energy when running at less than full capacity, and you can also save energy on cooler days. Variable inlet guide vanes are an ingenious yet simple option that, when installed on your centrifugal compressor, can deliver energy savings of up to 9 percent. By replacing a standard inlet
W'hen variable speed is used as a part-load control mechanism, centrifugal compressors szifjer a much smaller efficiency capacity while the variable inlet guide vane controlled compressor could be turned down 40% capacity defined as the smallest pressure drop measured for any of the four rake setting angles.
26 Sep 2011 On the one hand, they reasoned that the inlet vanes represented an unnecessary pressure drop. But on the other hand, they felt that they may provide some benefit by means of directing the air flow into the eye of the fan. It was a great question accompanied by some great observations along the lines of
In applications that require flow control the most energy effective technique is often variable speed control; alternatively inlet guide vanes can be used, of the market survey regarding capacity control are reported in the following sections, where the turndown rates are indicated in accordance to the following definition:.
12 Jun 2014 In exemplary embodiments, a centrifugal compressor equipped with a variable frequency drive and variable inlet guide vanes may be utilized. The method according to claim 9, wherein intermediate capacity range is defined in part by an inflection point of a compressor surge control boundary. 14.
no overload capacity variable suction pressure downstream of the valve. - low initial costs, high operating costs for part-load operation. Presented at the international Gas Turbine and Aeroengine 1: Suction throttling and adjustable inlet guide vane control. 7r. Fig. if one stage reaches Its individual surge defined on the.
A capacity control system for a refrigeration system including a compressor, a condenser, and an evaporator all connected in a closed refrigeration circuit, the compressor having a plurality of adjustable inlet guide vanes and driven by an internal combustion engine, signals indicating the condenser pressure; the evaporator
17 Apr 2014 CENTRIFUGAL COMPRESSOR INLET GUIDE VANE CONTROL. BACKGROUND OF THE INVENTION. [0001] The invention relates generally to chiller refrigeration systems and, more particularly, to a method of maximizing the cooling capacity of the chiller refrigeration system at start-up. [0002] In many
Inlet Butterfly Valve (IBV):. The Inlet Butterfly Valve may be driven electronically or pneumatically, and as it closes it creates a pressure drop across the valve, effectively reducing the inlet pressure into the compressor and throttling the compressor's ability to make pressure and subsequently flow. Inlet Guide Vanes or (IGV's):.
