It might be cool, but it isn't cool enough. Sorry I can't do Fahrenheit, but with your example roughly, say 22C chiller temp and 32C air temp 10 degree temp difference. Compare this to an aircon. -5C evaporator coil in, air temp 32C in and 12 C out. So a 37C temp difference gives a 20 deg output temp drop, but that translates to an air temp drop of half the difference or 10C drop because heat is continually being added, so 22C after a long while and that is with with a big evaporator/compressor. In your system using its ratios of in to out temp would mean a quarter cooling
, so a 5 C temp drop in output then halving the ambient temp difference, so a 2.5 C room temp drop. I think it will be worse as the system is very small and you have to add back the motor
heat. If you get even a 2C drop the chilled beers are on me.
