Question: To refresh air in a room, a counter flow heat exchanger, is mounted in the wall, drawing in outside air at 0.5C, 80% relative humidity

To refresh air in a room, a counter flow heat exchanger, is mounted in the wall, drawing in outside air at 0.5C, 80% relative humidity and pushing out room air, 40C, 50% relative humidity. Assume an exchange of 3 kg/min dry air in a SSSF device, and also that the room air exits the heat exchanger to the atmosphere at 23C. Find the net amount of water removed from the room, any liquid flow in the heat exchanger and (T, ) for the fresh air entering the room.
