WebFixed Head Pressure Control-- The WCFC can stage the condenser fan banks based upon a fixed head pressure setpoint. For fixed head operation, the controlling … Webcondensing temperature of 85 F on the design day), there is an optimum head pressure (i.e. a head pressure greater than the minimum achievable that will minimize the …
Webdesign head. If the operating condition requires more than 64% of design head, the centrifugal compressor will surge. Centrifugal compressors move gas through an open path between the low-pressure evaporator to the higher-pressure condenser. If the pressure diff erence (head) is too large, flow reversal will occur (surge).
WebThe change in molecular weight will have an impact on the number of stages (FIG. 2) of the compressor since a lower molecular weight calls for more required head to achieve the desired pressure, leading to greater pressure coefficient on the impeller. 3,4,5,6 It is always better to review the number of impellers/stages required with respect to all … bubble shooter deluxe onlineWebStaging Use of multiple compression stages raises the refrigerant pressure in the hot gas discharge of the compressor. This allows a higher condensing temperature which, while lowering the refrigeration efficiency, offers two benefits. First, elevated condensing temperatures may be required with air-cooled condensing in very hot locations. export contacts from iphone to excel fileWebAug 20, 2024 · I was assigned the task of creating a head pressure control for a cooler condenser and one for a freezer.
