INTRODUCTION
Real-World Energy Performance SUSTAINABILITY Johnson Controls pioneered the term “Real-World Energy” to illustrate the energy-saving potential of focusing on chiller performance during off-design conditions. Offdesign conditions are not only seen at part load, but at full load operation as well, by…

SUSTAINABILITY
Quiet Operating Range with Magnetic Bearing Technology Lower Direct and Indirect Environmental Impact. 98% of the Global Warming Potential (GWP) of a centrifugal chiller is from the indirect effect – the greenhouse gases produced to produce the electricity to run the chiller. 2% of the GWP is from…

for greater efficiency and less chiller cycling. The chiller
cycles off when the leaving chilled water temperature is below setpoint and is adjustable from 0.55°C below to a minimum of 2.2°C. Restart is adjustable from setpoint up to a max of 44.4°C. The panel will check for flow to avoid freeze up of the tubes. If flow is interrupted shutdown will occur…

WATER CIRCUITS
Flow Rate – For normal water chilling duty, evaporator and condenser flow rates are permitted at water velocity levels in the heat exchangers tubes of between 0.91 m/s (1.0 m/s for condensers) and 3.66 m/s. Two pass units are also limited to 134 kPA water pressure drop. Three pass limit is 201 kPA.…

MULTIPLE UNITS
Selection – Many applications require multiple units to meet the total capacity requirements as well as to provide flexibility and some degree of protection against equipment shutdown. There are several common unit arrangements for this type of application. The YORK YMC2 chiller has been designed to…

on request. Control of sound and vibration transmission
must be taken into account in the equipment room construction as well as in the selection and installation of the equipment. THERMAL INSULATION No appreciable operating economy can be achieved by thermally insulating the chiller. However, the chiller’s cold surfaces should be insulated with a vapour…
