How to calculate recovery time for a house in cooling mode?
(OP)
Hi guyz,
I am totally new to this site and looks like its a great place to post questions regarding engineering.
Anyways I am trying to calculate the approximate time required to recover the house temperature when going from unoccupied to occupied mode in cooling cycle. Thanks.

RE: How to calculate recovery time for a house in cooling mode?
V*Cp*dT/Qx
where
V is the volume of the space
Cp is the volumetric heat capacity of air
dT is the difference between unoccupied and desired temperature
Qx is the quasi-instantaneous excess capacity of your cooling system.

Thanks a lot for your reply, but can you please explain how can I find out the Cp and Qx? Thank you.
RE: How to calculate recovery time for a house in cooling mode?
Qx is rather more difficult. You could get a reasonable feel for the system's cooling capacity from the compressor's performance curves. The excess capacity is the difference between that and the cooling load at the same conditions.

Take the "V" out of HVAC and you are left with a HAC(k) job.
