Normal load is about 20-35F above ambient, 20F being a light load, and 35F being a heavy load.
I don't understand what you mean by "load", light or heavy ... 20-35F above ambient ? what does ambient have to do with load? are you assuming that the ambient is the "infiltration" load? No, by ambient, I am referring to condensing ambient. the case is indoors. typically I assume a constant 80'F for the air conditioner not working properly.
At 28F over ambient, this condenser is getting rid of a fairly heavy load of heat. Where does that heat load come from? The evaporator.
If the TXV's weren't somewhere in the ballpark, it would not be able to pick up this much load.
The evaporator coil does two things. It cools the air (sensible load) and it de-humidifies the air (latent load). It isn't picking up much sensible load (low dT), so it must be picking up a heavy latent load (lots of humidity).
Make sense? [/B]
