### GHR-AH REFRIGERATED AIR DRYER

Structure and FeatureDew points of the atmospheric pressure when the dew points under the pressure are changed 1, What is the atmospheric dew point when the pressure is 7kg/cm² and the dew point is 10°C under the pressure?           Find the dew point of 10°C on the right side of the table and you can find the intersecting point of the horizontal line A from the dew point of 10°C and the pressure line 7kand then you can obtain the atmospheric point of-17°C if you descend from the interesting point of the vertical line A 2, What is the atmospheric point when the pressure is 7kg/cm² and the dew point under the pressure is 4°C?           If you follow the B-B line  according to the above method, you can find the dew point of -22°C on the table 3, What is the atmospheric point when the pressure is 7kg/cm² and the dew point under the pressure is 4°C?           If you follow the C-C line according to the above method, you can find the dew point of -57°C on the table. Change of the dew point under the pressure in case of decompressinWhen the dried air in the pressure of 7kg/cm² and dew point of 4°C If decompressed down to the pressure of 3kg/cm², what is the change of the dewpoint under the pressure?           Find 4°C on the right side and the intersecting point of the Hori-zonal line B from and the pressure line of 7k and then descend from the intersecting point following the horizontal line of B and you calabtain above intersecting point with the pressure line 3k and then move to the right side to get the dew point of -5°C.
