車両用空気調和装置
Document Type and Number:
Japanese Patent JP7233915
Kind Code:
B2
Abstract:
[Problem] To provide a vehicle air-conditioning device that has improved responsiveness by avoiding a shortage of compressor capacity (target rotational speed) when shifting to an operation state in which the number of evaporators for evaporating a refrigerant increases. [Solution] The present invention has a first operation state in which the refrigerant is evaporated by a heat absorber 9 or a refrigerant-heat medium heat exchanger 64 and a second operation state in which the refrigerant is evaporated by both. The target rotational speed of the compressor 2 is calculated by F/F calculation based on the target heat absorber temperature TEO for the heat absorber temperature Te and the target heat medium temperature TWO for the heat medium temperature Tw, and in the second operation state, correction is performed in a direction in which the F/F operation amount calculated by the F/F calculation becomes larger than in the first operation state.
