Hello folks and HVAC guys/gals,
Have a question..Having a new house built, and they are installing the
Carrier VS8000 furnace and the 38TDB Condensor unit with the Infinity
control..I understand the system will run the AC on low speed to dehumidify,
what does the system do in the winter when humidity is higher than the
setting?? Will it run the furnace for heat and the AC for dehumidify or does
it not dehumidify in the winter time?
Thanks for your time and responses...
Where do you live? In most parts of the world it is cold in the winter
and the heat is on. The heating usually reduces the humidity enough or even
too much. You will not see any moisture removed, but the same amount of
moisture in warm air is much lower humidity (a relative number) than it was
when the same air was cold.
Because you're so close to the problem I bet you forgot that in the winter
time we just about always have to humidify. High, outside, humidity in the
winter does not always mean a lot of actual moisture in the air (lbs
water/cubic ft. of air). So when the air goes through the heating cycle the
amount of moisture in the air doesn't change but the Relative Humidity does
where, RH=amount of moisture in the air/amount of moisture that the air can
hold at the temperature of the air. Then end result is that after being
heated the air ends up being a little too dry.
Thanks for the responses..We live in Bastrop Tx (Austin area) and sometimes
we have a lot of rain in the winter and might have mild weather in which we
might open the doors. This might raise the humidity in the home to an
uncomfortable level and being the Infinity system is so advanced I thought
maybe it would run the AC during furnace operation, but I guess that would
really cut down the output of the furnace and probably overload the
compressor...I didn't think about that aspect....
