Thread: cooling without DX
02-01-2006, 04:41 PM #1
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.

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.Is this a Fabreze moment? C.Y.D. I'm voting white elephant. 2¢.
