Chiller definitions?
Chiller definitions?
(OP)
I have been selected to be over the chilled water system of my new job, at a plant that is currently being built. I understand about 75% of it all. My question comes into the terms associated with a chiller, lift, surge, condensor and evaporater saturation temp, dew point, enthalpy, humidity, etc. Is there a good source any where that can explain these in simple terms so I can understand what the technicians will be talking about? And any tips would be cool. It will be 5 York 2000 chillers, 5 primary pumps, 3 VFD secondary pumps. Design at 44F out and 68F in @ 32psi I think. Thanks for any help. I'll be here asking lots of dumb questions I'm sure. I do understand what is happening in the chillers, for the most part. Thanks for any help!





RE: Chiller definitions?
Any time lift is increased, power consumtion is increased.
SURGE- Whenever the lift exceeds the compressors ablity to provide the lift a reversal of gas flow from the condenser back to the evaporator takes place; this is called surge it will be repetitive unless the compressor is unloaded to relieve the lift(head).
3.- SATURATION TEMPERATURE: is when a refrigerant has a change of state and you have both liquid and vapor present such as in the evaporator and the condenser, that is to say when a vapor changes to a liquid (condenser) at a constant pressure and a liquid changes to a vapor(evaporator)at a constnt pressure
DEW POINT- The temperature at which air(vapor) changes state
to a liquid.
ENTHALPY- Also called total heat. In air conditioning it represents the heat energy in 1 lb of dry airplus it's associated water vapor. Enthalpy is measured by it's wet bulb temperature(sensor)
RELATIVE HUMIDITY- is is the weight of water vapor in the air as compared to the amount of water vapor at saturation for a given sample Sorry I coulden't find a web page with all that you were asking for so I am giving you the ones you mentened
