Ch8
Involves reducing the pressure in a refrigeration system to a micron gauge reading of 500 or below
What is deep vacuum
Daily maximum fine for intentionally venting refrigerants to atmosphere can be this high.
What is $27,500 ?
Orientation of a cylinder that is charging liquid refrigerant from a charging tank into a system.
What is upside down ?
All of these are examples, TXV, capillary tube, orifice.
What are Expansion devices ?
Electric circuit in which there is only one path for electrons to flow.
What is a series circuit ?
during a standing pressure test for leak checking, using this could create an explosive mixture.
What is air ?
To process refrigerant to new product specifications.
What is "Reclaim" or reclaiming ?
Side of system refrigerant in vapor form is added to.
What is low-pressure, or low side ?
Powered, natural, and solar are examples.
What is attic ventilation ?
electrical system composed of multiple loads connected in a manner to provide each load with full line voltage with switches connected in series to the loads.
What is a series parallel circuit ?
The best method of leak checking.
What is a standing pressure test ?
The element within refrigerants that damages the ozone layer.
What is chlorine ?
The best program at UTI austin.
What is HVAC ?
Where solar load originates.
What is the sun ?
the following are examples : motor, light bulb, electric heater.
What are loads ?
the pressure range at which the technician should valve off the vacuum pump when evacuating to a deep vacuum.
What is 500 to 300 microns ?
To remove refrigerant from a system without any testing or processing and then put it back into the system.
What is recovery ?
Used to help technicians perform a number of tasks, to include trapping all the refrigerant in the receiver to perform system service.
What is a king valve ?
Type of condensor that has more surface area than a standard condensor.
What is high efficiency ?
control circuit components are usually installed this way with the loads they control
What is in series ?
Represents the lowest vacuum.
What is 1000 microns ?
Process in which ozone is produced.
What is photosynthesis ?
Range of temperatures/pressures in which a blended refrigerant will condense.
What is glide ?
Needed to be installed on ducting traveling through hotter spaces.
What is insulation ?
amount of electrical pressure used or lost through components wired in series.
What is voltage drop ?
