Performed maintenance and diagnostics on a wine-cellar condensing unit; unit was dirty, cleaned, and then connected to digital gauges to collect detailed operational readings. Wine cellar return dry-bulb temperature: 52.2°F; wine cellar return wet-bulb temperature: 47.7°F; calculated relative humidity: approximately 72.5% RH; calculated dew point: approximately 43.6°F; suction pressure: 84.3 PSIG; R-404A evaporating saturation temperature: 38.9°F; suction-line temperature: 42.7°F; superheat: 3.4°F; discharge/head pressure: 269.1 PSIG; R-404A condensing saturation temperature: 109.3°F; liquid-line temperature: 103.1°F; subcooling: 5.9°F; outdoor ambient temperature: 94.4°F; condenser approach: 8.6°F; compression ratio: 2.87; recorded discharge-line temperature: 110.3°F; evaporator temperature difference (TD): 13.3°F; condenser temperature difference (TD): 15.0°F. Interpreting the readings indicated the unit is running very well.
