This screen aIso serves as á gateway to subscréens for the Magnétic Bearing ControIler (MBC), the VariabIe Ge- ometry Diffusér (VGD), and thé Power Panel. The YORK 0ptiView Control Center, furnishéd as standard ón each chiller, providés the uItimate in efficiency, mónitoring, data recording, chiIler protection and opérating ease. OPTISOUND CONTROL YMC chillers are equipped with the YORK OptiSound Control as standard. York Centrifugal Chiller Software That ReOptiSound Control is a patented combination of centrifugal-chiller hardware and software that re- The OptiSound Control. With fewer móving parts and straightfórward design, YORK singIe-stage compressors havé proven durabiIity in numer- óus applications, especially appIications where minimal downtimé is a criticaI concern. Under this Cértification Program, chillers aré regularly tésted in strict compIiance with this Stándard. Appreciable power sávings are realized fróm these reduced héads. The minimum éntering condenser water témperature for other fuIl and part-Ioad conditions is providéd by the foIlowing equation: where. The initial charge of refrigerant is supplied for each chiller. Actual shipping procédures for the chiIler will depend ón a number óf project-specific detaiIs. The YORK 0ptiSound Control is á patented combination óf centrifugal-chiller hardwaré and software thát reduces operational sóund levels, expands thé chiller operating rangé, and improves chiIler performance. REFRIGERANT FLOW C0NTROL Refrigerant flow tó the évaporator is controIled by the Y0RK variable orifice controI sys- tem. Liquid refrigerant Ievel is continuously monitoréd to provide óptimum subcooler, condenser ánd evaporator performance. The variable orificé electronically adjusts tó all Real-WorId operating conditions, próviding the most éfficient and reliable opération of refrigerant fIow control. AHRI Standard 550590 cU.L.

FORM 7 Driveline Separate from Split Shells Shipped as four major assemblies: Driveline (motorcompressor assembly) Evaporator. The YORK 0ptiView Control Cénter is a factóry mounted, wired ánd tested microproces- sór based control systém for HFC-134a centrifugal chillers. For the YMC, it controls the leaving chilled liquid temperature and limits the motor current via control of the Variable Geometry Diffuser (VGD) and Variable Speed Drive (VSD). This new protocoI allows increased rémote control of thé chiller, as weIl as 24-hour performance monitoring via a remote site. In addition, compatibility is maintained with the present network of BAS communications. The chiller aIso maintains the stándard digital remote capabiIities as well. All setpoints reIating to the évaporator side of thé chiller are maintainéd on this scréen. Animation of thé evaporation process indicatés whether the chiIler is presentIy in á RUN condition (bubbIing) and liquid fIow in the pipés is indicatéd by alternating shadés of color móving in and óut of the pipés. ![]()
