dear all
i am simulating a Five zone office building operated Monday - Friday 9AM to 6 PM
the cooling load was already calculated .
at present i am air conditioning East zone through ventilation by a packaged terminal air conditioning ,the air conditioner is power by photovoltaic panel via inverter regulator and battery bank .
various equation are made for signals of schedule alog with thermostat
temperature was maintained at pre defined value , but my problem is that air conditioners was operated even very low panel wattage and low battery AH, while no any grid power was taken by a large AC even 100W panel is attached
while i was already simulated a refrigerator in that case when power from solar / battery / panel is low then it will take grid powers
