Occupations | Fabricates and assembles components of refrigeration systems for environmental test equipment according to blueprints or schematic drawings and knowledge of refrigeration systems, using handtools, powered tools and welding equipment: Reads blueprints or schematic drawings to determine location, size, capacity, and type of components, such as compressor, condenser, expansion tank, valves, and tubing or piping needed to build refrigeration system. Mounts compressor, condenser, and other components in specified locations on frame, using handtools and arc or acetylene welding equipment. Cuts, bends, and brazes specified tubing to inlets and outlets of components to form liquid and suction lines of refrigeration system, using knowledge of metal properties. Installs expansion and control valves, using acetylene torch and wrenches. Adjusts valves according to specifications. Removes air from system and charges system with specified amount and type of refrigerant [GAS CHARGER (svc. ind. mach.)]. Tests lines, components, and connections for leaks with leak detector which indicates presence of refrigerant [GAS-LEAK TESTER (svc. ind. mach.)]. Attaches thermocouples to various points of refrigeration system and test-operates equipment to evaluate functioning and cooling capacity of system. Records pressure and temperature readings from gauges and $T3temperature potentiometer$T1 during test run. Compares reading with specifications to evaluate performance of system, and adjusts or replaces parts as indicated. May fabricate and assemble structural portions of test equipment. May assemble and mount electrical wiring circuits, controls, and recording devices. May fabricate and assemble cascade and multiple stage refrigeration systems. (references) |
| Installs and repairs industrial and commercial refrigerating systems according to blueprints and engineering specifications, using knowledge of refrigeration, structural layout, and function and design of components: Lays out reference points for installation of structural and functional components, using measuring instruments, such as tape, transit, plumb bob, levels, and square. Drills holes and installs mounting brackets and hangers into floor and walls of building. Lifts and aligns components into position, using hoist or block and tackle. Screws, bolts, rivets, welds, and brazes parts to assemble structural and functional components, such as motors, controls, switches, gauges, wiring harnesses, valves, pumps, compressors, condensers, cores, and pipes. Cuts, threads, and connects pipe to functional components and water or power system of premises [PIPE FITTER (construction) 862.281-018]. Pumps specified gas or fluid into system. Starts system, observes operation, reads gauges and instruments, and adjusts mechanisms, such as valves, controls, and pumps to control level of fluid, pressure, and temperature in system. Dismantles malfunctioning systems and tests components, using electrical, mechanical, and pneumatic testing equipment. Replaces or adjusts defective or worn parts to repair systems. May insulate shells and cabinets of systems. May install wiring to connect components to electric power source. May specialize in installing systems and be designated Refrigeration-System Installer (any industry). (references) | |
