C. Chillers: Insulate cold surfaces on chillers, including, but not limited to, evaporator bundles, condenser bundles, heat-recovery bundles, suction piping, compressor inlets, tube sheets, water boxes, and nozzles with one of the following:
D. Refrigeration System Testing: Provide technicians, instrumentation, tools, and equipment to test performance of chillers, cooling towers, refrigerant compressors and condensers, heat pumps, and other refrigeration systems. The CxA shall determine the sequence of testing and testing procedures for each equipment item and pipe section to be tested.
4. A coalescing type filter, rated for the full compressor output during system startup (low pressure), shall be installed immediately downstream of the accumulator. The filter shall be equipped with an automatic blow-down.
6. Use duplex air compressors sized for less than one third duty cycle. Size the storage tank to prohibit more than six starts an hour on any compressor. The storage tank shall be equipped with a timed blow-down.
8. Desiccant dryers shall be the heatless type, utilizing a twin tower design and skid mounted. The compressor shall be sized to include the blow down load from heatless desiccant dryers, if used. Regeneration shall be automatic. Dryers over 200 SCFM shall have an energy saving design that controls the regeneration blow-down on the total airflow through the unit. The regeneration blow-down shall be muffled. The dryer shall include mechanical pre-filters and after-filters. The dryer shall be sized for 25% over the instantaneous peak building load. The desiccant dryer shall be equipped with the following accessories:
2. Remove coarse particles of dirt and dust by drawing a clean, lintless cloth through tubing by means of a wire or electrician's tape.
3. Draw a clean, lintless cloth saturated with trichloroethylene through the tube or pipe. Continue this procedure until cloth is not discolored by dirt.
4. Draw a clean, lintless cloth, saturated with compressor oil, squeezed dry, through the tube or pipe to remove remaining lint. Inspect tube or pipe visually for remaining dirt and lint.
5. Finally, draw a clean, dry, lintless cloth through the tube or pipe.
6. Safety-relief-valve discharge piping is not required to be cleaned but is required to be open to allow unrestricted flow.
1. Comply with ASME B31.5, Chapter VI.
2. Test refrigerant piping, specialties, and receivers. Isolate compressor, condenser, evaporator, and safety devices from test pressure if they are not rated above the test pressure.
3. Test high- and low-pressure side piping of each system separately at not less than the pressures indicated in Part 1 "Performance Requirements" Article.
