cooling without DX

[dutchcool]

I went to a cooling exhibition today, and carrier europe showed there new DX free cooling system.
I a moderate climate like North europe this could safe some energy.
When the outsite temp. is less than the setpoint of the water you may not need to operate the compressor[s], the unit bypasses the TEV and a small pump circulates the refrigerant.
The ref. takes on the outside temp. in the condensor, and in liquide form, it flows to the evap.
The condensorfans and the pump[s] are running.
Lots of savings if you ask me.

That would be a good application for computer rooms and process cooling. Hmmmm... makes sense.

Our Canadian boys been doing this for a while now.
I think Toronto does this on a few of there buildings, if I remember right.

I've got one account that for 20 years has had R22 filled heat recovery coils (each tube-in-tube sealed with approx 50% saturated). No circulation, just gravity, ten rows thick and a slight angle down towards the exiting air. They claim 60% transfer and when it's 60,000cfm it adds up to saving.

The system you described sounds like it would work work quite well on cooler days.
