The Basic Cycle
the Heart
compressor
The point at which refrigerant gas condenses
condensing point
Installed in nearly every system, designed to protect from moisture and particulate.
filter drier
Hottest point in the system
hot gas discharge line
the movement of heat from where it is not wanted and relocating it to where it make little or no difference
Refrigeration
Heat exchanging coil that reject heat
condenser
At a specific temperature, a substance has a specific.....
pressure
Allows you to SEE into the system.
A transparent Lens that shows us if the system is proper charged
Site Glass
Has 100% liquid
liquid line
Heat energy moves in 2 directions.....
hot to cold, up
heat exchanging coil that absorbs heat
evaporator
The point at which refrigerant liquid evaporates
boiling point
an electromagnetic valve
solenoid
Should have low pressure Vapor
suction line
Absolute Zero= _______ degrees F
-459/-460
A long, small copper tube that connects high to low side. a type of metering device
cap tube
Sensible Heat raise to a substance beyond its change of state
Superheat
opens or closes off of a temperature shift
thermostat
the line that could exist at 2 points in the system
suction line
The sensible heat loss to a substance after change of state
subcooling
The coldest part in the system
evaporator inlet
occurs during change of state
Latent heat transfer
opens or closes off of a pressure shift
pressure switch
The line we take a sub cooling reading from
liquid line
First Rule of Thermal dynamics
energy cannot be created or destroyed
