^aAssuming 5 K heat transfer temperature difference on each side.

^bAssuming a linear characteristic curve between temperature span and cooling. (heating) power, which implies that the maximum cooling (heating) power is twice the value listed in the table.

^cDew point temperature corresponding to the standard dry bulb of 27 °C and wet bulb of 19 °C.

^dDew point temperature corresponding to the standard dry bulb of 27 °C and wet bulb of 24 °C.
