Chiller definitions? 1

[Flip3]

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!

1 LIFT- Is defined as the ability of the compressor to lift efrigerant gas from the cooler pressure levelto the condenser pressure level.The lift(or head which has to be overcome) can be measured in degrees F. there are a lot of varibles which affect lift A typical lift may be about 70*F.
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
