2.12: Heat Gain from Dehumidifier Pump and Piping:
{"Image DocumentName": "2.12: Heat Gain from Dehumidifier Pump and Piping:", "Image ImageDescription": "The horsepower required to pump water through the dehumidifier adds heat to the system and is to be considered like that of other electric motors. For this purpose pump efficiencies may be assumed as 50 percent for small pumps and 70 percent for large pumps. The heat gain of dehumidifier piping may be calculated as a percentage of the grand total heat as follows: (i) Very little external piping: 1 % of GTH. (ii) Average external piping: 20% of GTH. (iii) Extensive external piping: 4% of GTH. Note: Percent Addition to Grand Total Heat: It is to be noted that all heat gains after the room are not to be added to room heat gains but to the grand total heat load that directly falls on the conditioning equipment. These include the return air duct heat.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
