Residential Units, Rooftop unit

broken window units for diagnostic practice — There are a number of window units with programmed faults which students diagnose and repair

compressors — Condensers contain compressors and work in concert with the air units and evaporators inside the building

inside furnace — Inside is the blower motor, the furnace assembly and the evaporator

students checking 20 ton rooftop unit

Commercial Refrigerator/Freezer (HART 2442 Commercial Refrigeration)

einstein control w/ freezer door — Commercial walk-in Freezer/Cooler “Einstein” programmable Controller panel

Einstein fridge-freezer control panel — Control panel is next to the door of the walk-in freezer

Evaporator and motor inside commercial fridge — Evaporator unit and fan motor on the refrigerator side

commercial freezer chiller w black heating wrap — The commercial unit’s evaporator is in the freezer.

Refrigerant recovery

Refrigerant is recovered with the “stinger”, then a vacuum pump removes the noncondensibles such as air and moisture.

stinger w tank — Bacharach “stinger” recovery unit with service cylinder

The filter collects dirt and other non condensibles such as air and moisture

digital vacuum w gauge — Vacuum pump evacuates the system down to 29.9 inches vacuum. Digital vacuum gauge used to determine the micron evacuation level.

electronic refrigerant recovery scale — Electronic scale, which is accurate to within 1/4 ounce, is used to weigh and dispense refrigerant charges
