본 발명은 차량의 실내로 제공하는 공기를 히팅하거나, 또는 냉각하여 차량의 실내 온도를 지정온도로 유지하도록 하는 차량용 냉난방시스템에 관한 것으로, 더욱 상세하게는 냉각수와 냉매가 서로 열교환하는 칠러를 구비하여, 난방시에는 자동차 내의 폐열을 사용하므로 적상이 발생하지 않고, 냉매의 흐름 전환을 위한 방향전환 밸브는 2개를 두어, 냉방 성능과 효율의 저하를 방지하고, 차량공조유닛에 에바포레이터와 별도로 난방을 위한 열교환기인 실내열교환기 및 보조열원인 보조히터를 구비하여, 자동차에서 전방시계 확보를 위해 제습기능을 원활하게 수행할 수 있는 차량용 냉난방시스템을 제공한다.

    The present invention relates to an air conditioning and heating system for a vehicle for maintaining an indoor temperature of a vehicle at a preset temperature by cooling or heating air provided for the inside of the vehicle and, more specifically, to an air conditioning and heating system for a vehicle, comprising: a chiller which allows a coolant and a refrigerant to exchange heat with each other to prevent frost using waste heat inside the vehicle during heating; two direction changing valves for changing a flow of the refrigerant so as to prevent degradation of cooling performance and efficiency; and an indoor heat exchanger which is a heat exchanger additionally required for heating together with an evaporator in a vehicle air conditioning unit and an auxiliary heater which is an auxiliary heat source to allow a smooth dehumidification operation to secure a clear front view of the vehicle.
