Title:
AIR CONDITIONER
Document Type and Number:
Japanese Patent JP2010000964
Kind Code:
A
Abstract:

To sufficiently control the temperature of the air having passed through a heat exchanger 9 for cooling.

An electronic control device 70 increases control gains Kp, Ki compared to the case when a cooling load is determined to be small when the cooling load is determined to be large. The larger the control gains Kp, Ki become, the larger the control response of a refrigerant discharge capacity of a compressor 11 having a temperature deviation E(n) to be input becomes. When the cooling load is determined to be large, the control response of the refrigerant discharge capacity of the compressor 11 becomes large compared to the case when the cooling load is determined to be small. When the cooling load is large, the delay caused for reaching the target temperature TEO of the temperature of the air TE becomes short. When the cooling load is small, the control response of the refrigerant discharge capacity becomes small compared to the case when the cooling load is large, and therefore when the cooling load is small, hunting hardly occurs in controlling of the temperature of the air TE.
