FORM 160.77-O2 ISSUE DATE: 10/23/2020 2 JOHNSON CONTROLS This equipment is a relatively complicated apparatus. After cooling building load, chilled water temperature increases and then returns back to chiller evaporator. The amount of cooling generated needs to vary to match the load, otherwise too much heat can be removed and this will cause the chiller to freeze. Centrifugal water chillers These machines are efficient, typically producing a cooling effect two-to-three times greater than the required energy input. The YORK® YK has a wide range of application uses, including heat pump capability. Vane guides sit directly in the flow path of the refrigerant and can be controlled to change their position. With a wide range of water-cooled chiller types (scroll, screw, and centrifugal), capacities (16 to 5,500 Tons) and sustainable refrigerant options, Carrier is a leader in the industry. of centrifugal chiller hardware and software that expands the chiller operating range and improves chiller performance. Centrifugal chillers are available in capacity ranging from hundreds to thousands of tons. IM 1044-4 Centrifugal Chillers 7 Assuming that there are no sudden load changes and that the chiller plant has reasonable turndown, a rule of thumb of “gallons of water volume equal to two to three times the chilled water gpm flow rate” is often used. The Carrier 19XR/19XRV with a COP up to 6.5 (AHRI conditions) and an IPLV up to 7.4 or up to 10.5 with VFD centrifugal chillers provide exceptional value by achieving energy efficiency levels as high as 6.8 (COPr) utilizing proven technology designed specifically for chlorine-free refrigerants. The more closed the vane guide, the greater the angle of entry into the impeller. The Model CVGF chiller is ideal for offi ce, hospital, school, hotel, retail store and industrial buildings. In evaporator, refrigerant vaporizes to absorb heat from returned chilled water and cool it to the set point temperature. If the angle of entry is changed, then the refrigerant flows slower through the compressor and volute, this reduces the kinetic energy and pressure. Provides wider operation range at a low-load condition, and prevents stall from discharge gas for stable operation. Why to use a centrifugal chiller. ADVANCED INNOVATIONS FOR UNRIVALED PERFORMANCE, PROVEN EXPERIENCE IN APPLICATIONS, SERVICE AND SUPPORT. As mentioned, the vane guides sit in the flow path of the refrigerant.
