[BLDG-SIM] Nighttime setback control

[Younju Yoon]

Dear Building Simulation List,

I am trying to implement nighttime set-back and set-up control in my
simulation space using PSZ system. 

The following are cooling and heating temperature schedules and fan
operation schedule.

 

HEAT-1         = DAY-SCHEDULE  (1,6)(90)  (7,22)(76) (23,24)(90) .. 

HEAT-2         = DAY-SCHEDULE  (1,6)(90)  (7,18)(76) (19,24)(90) .. 

HEAT-3         = DAY-SCHEDULE  (1,24) (90) ..

HEAT-SCH    = WEEK-SCHEDULE  (WD) HEAT-1 (SAT) HEAT-2 (SUN,HOL) HEAT-3  ..

 

COOL-1         = DAY-SCHEDULE  (1,6)(55) (7,22)(70) (23,24)(55) ..

COOL-2         = DAY-SCHEDULE  (1,6)(55) (7,18)(70) (19,24)(55) ..

COOL-3         = DAY-SCHEDULE  (1,24)(55)   ..

COOL-SCH    = WEEK-SCHEDULE (WD) COOL-1 (SAT) COOL-2 (SUN,HOL) COOL-3 ..

 

FAN-1         = DAY-SCHEDULE  (1,4)(0) (5,6) (-999)  (7,22)(1)  (23,24)(0)
.. 

FAN-2         = DAY-SCHEDULE  (1,4)(0) (5,6)(-999) (7,18)(1) (19,24)(0) .. 

FAN-3         = DAY-SCHEDULE  (1,24) (0) .

FAN-SCH    = WEEK-SCHEDULE   (WD) FAN-1 (SAT) FAN-2 (SUN,HOL) FAN-3  ..

 

If I use NIGHT-CYCLE-CTRL = CYCLE-ON-ANY, the fan operates all day and
maintains the thermostat temperature for the conditioned zone even during
the times of the fan being set off. If I don't use NIGHT-CYCLE-CTRL =
CYCLE-ON-ANY, the conditioned zone temperature increases beyond 90F, which I
want to keep as the maximum allowable zone temperature.

 

Am I missing something? Is there any way I can successfully implement the
nighttime setback temperature control?

 

I really appreciate any advice in advance.

 

Thanks,

Younju
