I have a 2 ton split geosystem with a desuperheater used to keep a large cotage from freezing in the winter but do not use the desuperheater since I'm not there enough to justify plumbing it into the hot water system, but I was wondering if I set the desuperheater output loop into a liquid to air exchanger would my overall efficiency be increased? The system is normally used to just keep the cottage above freezing temperatures in the winter. I think the desuperheater circuit provides an extra 6K btu's. Would it be worthwile to plumb it into another exchanger or into a thermal mass water tank in this case? Any opinions would be appreciated.
Thanks,
Tim Dawson

No. The desuperheater only reroutes some of the capacity, it does not give you more. |

I agree. Keep the DSH turned off if you are not using it. |

If the DSH is unused (no water pumped through it) refrigerant discharged from the compressor carries all its heat to the air coil |

Thanks for the info.
Was'nt sure if I could get another 6Kbtus out of it, but that makes sense.
Thanks again,

Actually, I think there would be a slight efficiency gain on paper - you would effectively be increasing the size of the of the condenser, which would drop your condensing temp closer to your water or air temp, reducing compressor load. In practice, though, this gain would probably be too small to measure, unless the condenser was really undersized to start with. |
