Title:
VEHICLE AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/112633
Kind Code:
A1
Abstract:
[Problem] To secure a desired airflow rate without increasing the air blowing capacity when performing maximum cooling or maximum heating by causing air to flow continuously to multiple heat exchangers in an air-conditioning case. [Solution] Provided is a vehicle air-conditioning device comprising: an air-conditioning case equipped with multiple heat exchangers; and a heat medium circuit in which a heated or cooled heat medium flows through the heat exchangers and is circulated, the vehicle air-conditioning device heating or cooling air which is blown into the air-conditioning case and which passes through the heat exchangers, wherein the heat medium circuit causes the heat medium to flow in series or in parallel to a first heat exchanger provided on the upwind side and a second heat exchanger provided on the downwind side inside the air-conditioning case, the air-conditioning case comprises a main airflow channel along which air flows continuously to the first and second heat exchangers and a bypass airflow channel along which air that has passed through the first heat exchanger flows while bypassing the second heat exchanger, and the bypass airflow channel is provided with an airflow-regulating damper that regulates the airflow rate in the bypass airflow channel.
