And find your variable name in the .RDD output file.

Hey all.. thanks for the suggestions.. Im working on them.
Could anyone tell me wot to write to get the latent cooling rate. report?

Amit,
I too looked at your file and added an ABUPS report--you are indeed
getting some small amount of heating as purchased heating:
1.51 MJ (compared to 49.81 MJ electricity for internal loads). Like
Brent suggests, I would change your setpoint control to dual and
look at your internal loads as they seem high. Overall energy
intensity is 1411.36 MJ/m2 which is about double what I would expect
for a house.

Amit,
I took a very quick look at your file (but didn't run it). I don't know of
a refrigerator that will use 1,040 watts all day long; this could be
heating the space. I would also change to dual heating and cooling
setpoint control.

Thanks for responding. I have checked the internal loads schedules and also
the weather data belongs Sterling Va or Washington Dc, which has really
cold winters. My model does not involve natural ventilation but a
betweenglass shade with airflow.(outside to outside).
I have posted my file house.idf on the support group files area for further
investigation. I am goingout of ideas.
thanks

If the zone temperature is greater than the thermostat set point
temperature, the heating rate should be 0. Does your simulation use
outdoor ventilation air or infiltration? Does the occupants/equipment
schedules produce enough heat to raise the zone air temperature? Is you
climate cold enough to require heating? Something in your input deck is
heating the zone which in turn disables the heating coil.
Search the example files to find a system similar to yours and
familiarize yourself with that input deck.
If you can't find a solution, upload your input deck to the support
group files area.
