To all, thanks in advance for the advices.
I'm now working on a warehouse in australia and the client/archi wants to hv a natural vent. without any fan inplace for exhaust.
idea is we make an openning on ground level for makeup air and have some chimney like openning with cap for stopping...
Hi, not sure if i've missed something,
when you say compression, it's in cooling mode, how can a heat pump has a better cop by utilising the heat at heating mode?? since heat pump works on cooling and heating, but not simutaneously.
