PROBLEM TO BE SOLVED: To provide a refrigeration cycle for airconditioning a vehicle comprising an inner heat exchanger and a vehicle mounted with the same, which can suppress decline in a performance coefficient without addition of components.SOLUTION: A refrigeration cycle 1 of a vehicular air conditioner comprises: a refrigerant circuit 100 including a compressor 2, a capacitor 3, an electronic control-type inflation valve 4 and an evaporator 5; an inner heat exchanger 10; a pressure sensor 31 that senses pressure of a refrigerant between the capacitor and the inner heat exchanger; a first temperature sensor 32 that detects a temperature of the evaporator or a second temperature sensor 33 that has a measurement point between the evaporator and the inner heat exchanger; and a valve aperture control device 40. The valve aperture control device adopts as a degree of superheat a value of a calculated degree of superheat calculated using the detected value by the first temperature sensor or the detected value by the second temperature sensor.SELECTED DRAWING: Figure 1

    【課題】本発明の目的は、内部熱交換器を備えた車両空調用の冷凍サイクル及びこれを搭載した車両に関し、部品を追加することなく、成績係数の低下を抑制することができる内部熱交換器を備えた車両空調用の冷凍サイクル及びこれを搭載した車両を提供することである。【解決手段】本発明に係る車両用空調装置の冷凍サイクル1は、圧縮機2と凝縮器3と電子制御式膨張弁4と蒸発器5とを含む冷媒回路100と、内部熱交換器10と、凝縮器と内部熱交換器との間の冷媒の圧力を検知する圧力センサ31と、蒸発器の温度を検知する第1の温度センサ32又は蒸発器と内部熱交換器との間に測定点を有する第2の温度センサ33と、弁開度制御装置40と、を備え、弁開度制御装置は、パラメータとして圧力センサの検出値と、第1の温度センサの検出値又は第2の温度センサの検出値とを用いて算出された算出過熱度の値を過熱度として採用する。【選択図】図1
