This means that while the air moves from left to right, the substance is traveling from right to left. All coils are examined in table-flow measures also it provides maximum efficiency. You can lose 15% of the capacity whenever a HVAC coil is piped backwards. This is the key reason why deeper HVAC coils are designated as suitable or left hand. Table-movement has negligible effect on 1-2 row coils.
Cooling coils which can be larger than 2 rows require a hand name. All coils except steam coils should be installed in a counter-flow design. That is especially true for HVAC coils with three lines or even more. Counter-stream refers to the course of the air over the fins in accordance with the liquid inside the tubes.

Whether residential or commercial application, you will want dehumidifier that is constructed for the application, your evaporation rate, your air flow as well as your design needs.
