| 1 | A. choose freezing dryer can make temperature-23 ℃ dew point. | |
| 2 | Dew point and humidity measurement experience would be a plus. | |
| 3 | Double - condenser adopted , low temperature of recycling air and low dew-point assured. | |
| 4 | Air conditioning systems help control humidity by cooling the return space air below the dew point. | |
| 5 | While the air mass is moving up the slope, it is cooled beyond its dew point and produces fog. |
