No they don't have it at the moment, but while researching for greenhouse cooling, I've come across them.
the analogy is like this:
Traditional AC: we compress the gas, then flow it through an orifice, then have it expand rapidly so it absorbs the heat around it. We simply use heat exchangers to isolate refrigerant and ambient air.
Traditional evaporative cooling: we blow air over evaporators, the air gets cooled by water evaporation.
M-cycle: the working "refrigerant" is air. Some air is cooled evaporatively while at the same time cooling the liquid used for evaporative cooling, and thus the temperature can go below wet bulb temperature without using compressor. The key is successive introduction of the working air successively through the pores of the wet evaporative surface. Very ingenious idea that I am amazed. Very creative indeed, truly unique and very efficient.
