If a larger mass of warm air has to pass through it, more energy is transferred, through the evaporator's fins (so that even the evaporator's design and, in particular, its exchange surface play an important part) from the air to the liquid refrigerant allowed inside it by the TEV or orifice tube so it expands more and, along with the absolute pressure inside the evaporator, the refrigerant's vapor superheat (the delta between the boiling point of the fluid at a certain absolute pressure and the temperature of the vapour) increases, since after expanding into saturated vapour, it has enough time to catch enough heat to warm up further by vaporizing the remaining liquid (an important property of a superheated vapour is that no fluid in the liquid state is carried around by the vapour, unlike with saturated vapour).

As others have noted, the IPCC Team has gone absolutely feral about Salby's research and the most recent paper by Dr Roy Spencer, at the University of Alabama (On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earth's Radiant Energy Balance), for one simple reason: both are based on empirical, undoctored satellite observations, which, depending on the measure required, now extend into the past by up to 32 years, i.e. long enough to begin evaluating real climate trends; whereas much of the Team's science in AR4 (2007) is based on primitive climate models generated from primitive and potentially unreliable land measurements and proxies, which have been «filtered» to achieve certain artificial realities (There are other more scathing descriptions of this process I won't use).
