Title:
AIR CONDITIONING SYSTEM USING OUTSIDE AIR, AND OUTSIDE AIR HEAT EXCHANGE SYSTEM OF THE SAME
Document Type and Number:
Japanese Patent JP2012193903
Kind Code:
A
Abstract:
To maximize the coefficient of performance of an outside air heat exchange system or air conditioning system using outside air.
In a control device 30, the coefficient of performance and an estimated coefficient of performance are determined based on a measured temperature in the charge and discharge of the outside air by thermometers 21, 22, the power consumption of a fan 11b and a pump 13 by power meters 23, 24, and the number of rotations and virtual number of rotations of the fan 11b, and based on the magnitude correlation of the determined coefficients, the number of rotations of the fan 11b is increased or decreased so as to improve the coefficient of performance.
