Compressor
What is the Compressor
is a coil of metal tubing, responsible for absorbing heat from the refrigerant cycle
What is the Evaporator
state of the gas when it leaves the condenser
what is high pressure liquid refrigerant
opens the needle and seat on a TEV
what is sensing bulb pressure
the vapor side of a recovery bottle is determined by
what is read the valve handle
a compressor in which all the components are sealed inside of its casing.
What is Hermetic
the type of heat that is absorbed in the evaporator
what is latent heat
enters the condenser
what is high pressure vapor refrigerant
the purpose of the TEV/ metering device
what is to maintain superheat
recommended vacuum amount, ensures there is no moisture left in the system
what is 500 microns
primary function is to trip compressor offline when compressor windings overheat.
What is Motor Protection Module?
This is used to move air across the evaporator to apply heat load to the refrigerant system
what is the evaporator fan
De-superheat, condense , Subcool
what are the three phases of the condenser
this has to be overcome by the sensing bulb to open the needle and seat on a txv
what is the spring pressure and equalization pressure
a recovery unit that does not use the system to evacuate the refrigerant
what is a stand alone recovery unit
this is used to cool the compressor
what is the evap "rule of thumb" for superheat
what is the average of 10 degrees, range 5-20 degrees
this is done by taking saturated temperature and subtracting it from liquid line temperature
what is subcooling
when ___ ___ ___ overcomes the bulb pressure and closes the valve, effectively increasing your superheat
what is increasing spring pressure of the txv
should be done before you charge a system with your gauges
what is purge your gauges of air
this is used to prevent flooding and slugging starts
what is the crank case heater, and liquid line solenoid
a superheat of over 20 degrees is ___ the evaporator
what is starving
a system that has a subcool of over 20 degrees in an ambient temperature of 95 degrees, and a superheat of 5 degrees
what is overcharged, and miss adjusted txv
__ + __= Diaphragm pressure
these are the three R's of refrigerant
what is reclaim, recycle , recover
