An experimental heat pump dehumidifier is described. Actual coefficients of performance (COP) A are plotted against the gross temperature lift ( T CO ‐ T EV ) for various bypass ratios and air velocities. Interpolated values of (COP) A for a specified temperature lift were obtained by fitting each set for various dry bulb temperatures of air leaving the humidifier using a linear equation. These values of (COP) A are plotted against the linear velocity of the air stream approaching the evaporator at different dry bulb temperatures. The curves show a maximum of (COP) A at approach velocities in the region of 1·6 ms −1 .
