Title:
ARITHMETIC VENTILATION SYSTEM FOR PREDICTIVE HEATING VALUE IN INTERNAL COMBUSTION POWER STATION
Document Type and Number:
Japanese Patent JPH02115908
Kind Code:
A
Abstract:
PURPOSE:To control an air temperature in a power station at an appropriate range, to evade the overcooling of equipment, and to save driving power for a charging fan for ventilation and a ventilation fan by controlling the amount of rotation of a blower from the arithmetic value of a ventilation air quantity. CONSTITUTION:Firstly, a heating value H is obtained from an outside air temperature T1 and the operation number (n) of generators. The value H is found from the sum of the common heating value Ho of the power station and the heating value He from one engine. The optimum ventilation air quantity Q is found from the value H and the cooling capacity DELTAT of an outside air taking in air temperature that changes seasonally or based on meteorological status, and a control quantity to control the rotation of the blower BLW based on the quantity Q is supplied to an inverter. The inverter controls the rotation of the blower BLW so as to reduce a deviation quantity. In such a way, appropriate ventilation can be performed for the heating value H that changes from time to time.
