High air volume out a little hole.
We are fitting a 2kw condenser in a cellar but -and it is a big but- we only have 100 dia in and out drain pipes to the outside(both are only 500mm long) for ventilation.
Would it be possible to fit a big fan on each to give sufficient airflow -or can any one think of a way to get enough air in/out to keep the condenser satisfied? Bearing in mind it will be cycling anyway so the heat is not constant but the fans will be...

Re: High air volume out a little hole.
Yes fitting fans designed for the right static pressure and volume required sounds like a good idea.
But why would the fans run permanently?
A thermostat and a relay would control them according to the requirements, surely?

Just fit a relay to switch the fans in line with the compressor contactor.

Re: High air volume out a little hole.
and I was expected to know that how ???
A word of caution with heat pumps indoors.
I came across a site some time back that had fitted a HP inside complete with drain tray underneath to catch the defrost water which then drained into a tanked condensate pump (Little Giant).
When in heating mode the area got so cold that the drained water began freezing. The drain tray turned into a block of ice and the freeze up continued down to the pump unit.
Whenever the unit was turned off and the ice could melt a little they ended up with a flooded room.
edit: I knew I'd written about this before and with a photo...
