I have an application that uses a heat pump and an air handling unit to heat/cool several different areas. The problem I have is that with only one air temerature available all except the largest area are too hot or to cold. My solution is to put actuator controlled dampers on all of the outlets except in the main area enabling them to shut off the air to any area should it be come too hot or too cold. I have to say I have fresh air to all areas via another source.
What I need is a controller that will sense the duct temperature behind the damper compare it to the room termerature that is being requested and decide to open the damper if the air in the room is hotter or colder depending on the room requirement. Please see the example below
duct temp 26 room temp 20 stat set 22 = open damper
duct temp 26 room temp 23 sat set 22 = close damper
Duct temp 17 room temp 26 sat set 21 = open damper
Duct temp 17 room temp 21 stat set 21= close damper
Can any one help, I know carrier do something withh VVT that is similar to this are there any other manufactures who can offer this sort of control.:confused: :confused: :) :rolleyes: :cool:
