AIR CONDITIONING SYSTEM

To provide an air conditioning system which can improve efficiency of a refrigeration cycle when heating air.SOLUTION: An air conditioning system includes a motor compressor for compressing a refrigerant by operation of an electric motor, a first heat exchanger 31 for heating air flowing through an indoor passage 112 for guiding the air indoors, a second heat exchanger 32 for absorbing heat of air flowing through an outdoor passage 111 for guiding the air outdoors, and a bypass passage 15 where an air flow upstream side is arranged on the indoor passage, and an air flow downstream side is arranged on an air flow upstream side of the second heat exchanger of the outdoor passage. The air conditioning system includes a motor compressor for compressing a refrigerant by operation of an electric motor, a first heat exchanger 31 for heating air flowing through an indoor passage for guiding the air indoors, a second heat exchanger 32 for absorbing heat of air flowing through an outdoor passage for guiding the air outdoors, a bypass passage 15 for guiding the air flowing through the outdoor passage to the indoor passage, and a flow rate control part 50 for controlling the flow rate of the air flowing through the bypass passage, and controlling the temperature of the air flowing through the indoor passage.SELECTED DRAWING: Figure 1 【課題】空気を加熱する際の冷凍サイクルの効率を向上可能な空調システムを提供すること。【解決手段】空調システムは、電動モータの作動によって冷媒を圧縮する電動圧縮機と、室内へ導く室内通路１１２を流れる空気を加熱する第１熱交換器３１と、室外へ導く室外通路１１１を流れる空気から吸熱する第２熱交換器３２と、空気流れ上流側が室内通路に配置され、空気流れ下流側が室外通路の第２熱交換器より空気流れ上流側に配置されるバイパス通路１５と、を備える。また、空調システムは、電動モータの作動によって冷媒を圧縮する電動圧縮機と、室内へ導く室内通路を流れる空気を加熱する第１熱交換器３１と、室外へ導く室外通路を流れる空気から吸熱する第２熱交換器３２と、室外通路を流れる空気を室内通路へ導くバイパス通路１５と、バイパス通路を流れる空気の流量を調整して室内通路を流れる空気の温度を調整する流量調整部５０と、を備える。【選択図】図１
