　（８－１）冷房運転
　冷房運転時には、室外熱交換器１１が冷媒の放熱器となり室内熱交換器５１が冷媒の蒸発器となるように、四路切換弁１０の接続状態が切り換えられる（図１の実線参照）。冷媒回路６において、冷凍サイクルの低圧のガス冷媒は、圧縮機８に吸入され、冷凍サイクルの高圧になるまで圧縮された後に吐出される。圧縮機８から吐出された高圧のガス冷媒は、四路切換弁１０を通じて、室外熱交換器１１に送られる。室外熱交換器１１に送られた高圧のガス冷媒は、冷媒の放熱器として機能する室外熱交換器１１において、室外ファン１５によって冷却源として供給される室外空気と熱交換を行って放熱して、高圧の液冷媒になる。この高圧の液冷媒は、室外膨張弁１２を通過する際に冷凍サイクルにおける低圧になるまで減圧され、気液二相状態の冷媒となって、液側閉鎖弁１３および液冷媒連絡管４を通じて、室内ユニット３に送られる。 (8-1) Cooling Operation During the cooling operation, the connection state of the four-way switching valve 10 is switched so that the outdoor heat exchanger 11 becomes a refrigerant radiator and the indoor heat exchanger 51 becomes a refrigerant evaporator (see FIG. See solid line in 1). In the refrigerant circuit 6, the low-pressure gas refrigerant in the refrigeration cycle is drawn into the compressor 8 and compressed to a high pressure in the refrigeration cycle and then discharged. The high-pressure gas refrigerant discharged from the compressor 8 is sent to the outdoor heat exchanger 11 through the four-way switching valve 10. The high-pressure gas refrigerant sent to the outdoor heat exchanger 11 exchanges heat with the outdoor air supplied as a cooling source by the outdoor fan 15 in the outdoor heat exchanger 11 functioning as a refrigerant radiator, and dissipates heat Become a high pressure liquid refrigerant. When passing through the outdoor expansion valve 12, the high-pressure liquid refrigerant is decompressed to a low pressure in the refrigeration cycle, becomes a gas-liquid two-phase refrigerant, and passes through the liquid side shut-off valve 13 and the liquid refrigerant communication pipe 4 It is sent to the indoor unit 3.
　低圧の気液二相状態の冷媒は、室内熱交換器５１において、冷房運転時は室内ファン５２によって加熱源として供給される室内空気と熱交換を行って蒸発する。これにより、室内熱交換器５１を通過する空気は冷却され、室内の冷房が行われる。室内熱交換器５１において蒸発した低圧のガス冷媒は、ガス冷媒連絡管５を通じて、室外ユニット２に送られる。 The low-pressure gas-liquid two-phase refrigerant exchanges heat with the indoor air supplied as a heating source by the indoor fan 52 in the indoor heat exchanger 51 during the cooling operation to evaporate. Thus, the air passing through the indoor heat exchanger 51 is cooled, and the room is cooled. The low pressure gas refrigerant evaporated in the indoor heat exchanger 51 is sent to the outdoor unit 2 through the gas refrigerant communication pipe 5.
　室外ユニット２に送られた低圧のガス冷媒は、ガス側閉鎖弁１４、四路切換弁１０およびアキュムレータ７を通じて、再び、圧縮機８に吸入される。冷房運転では、以上のようにして、冷媒が冷媒回路６を循環する。 The low-pressure gas refrigerant sent to the outdoor unit 2 is again sucked into the compressor 8 through the gas-side shutoff valve 14, the four-way switching valve 10 and the accumulator 7.

　（８－２）暖房運転
　暖房運転時には、室外熱交換器１１が冷媒の蒸発器となり室内熱交換器５１が冷媒の放熱器となるように、四路切換弁１０の接続状態が切り換えられる（図１の破線参照）。冷媒回路６において、冷凍サイクルの低圧のガス冷媒は、圧縮機８に吸入され、冷凍サイクルの高圧になるまで圧縮された後に吐出される。圧縮機８から吐出された高圧のガス冷媒は、四路切換弁１０、ガス側閉鎖弁１４およびガス冷媒連絡管５を通じて、室内ユニット３に送られる。 (8-2) Heating Operation During the heating operation, the connection state of the four-way switching valve 10 is switched so that the outdoor heat exchanger 11 becomes the refrigerant evaporator and the indoor heat exchanger 51 becomes the refrigerant radiator (see FIG. See the dashed line in 1). In the refrigerant circuit 6, the low-pressure gas refrigerant in the refrigeration cycle is drawn into the compressor 8 and compressed to a high pressure in the refrigeration cycle and then discharged. The high-pressure gas refrigerant discharged from the compressor 8 is sent to the indoor unit 3 through the four-way switching valve 10, the gas side shut-off valve 14 and the gas refrigerant communication pipe 5.
　高圧のガス冷媒は、室内熱交換器５１において、室内ファン５２によって冷却源として供給される室内空気と熱交換を行って放熱して、高圧の液冷媒になる。これにより、室内熱交換器５１を通過する空気は加熱され、室内の暖房が行われる。室内熱交換器５１で放熱した高圧の液冷媒は、液冷媒連絡管４を通じて、室外ユニット２に送られる。 The high-pressure gas refrigerant exchanges heat with the indoor air supplied as a cooling source by the indoor fan 52 in the indoor heat exchanger 51, radiates heat, and becomes a high-pressure liquid refrigerant. Thus, the air passing through the indoor heat exchanger 51 is heated, and the room is heated. The high-pressure liquid refrigerant that has dissipated heat by the indoor heat exchanger 51 is sent to the outdoor unit 2 through the liquid refrigerant communication pipe 4.
　室外ユニット２に送られた高圧の液冷媒は、液側閉鎖弁１３を通じて、室外膨張弁１２において冷凍サイクルの低圧まで減圧され、低圧の気液二相状態の冷媒になる。室外膨張弁１２で減圧された低圧の気液二相状態の冷媒は、冷媒の蒸発器として機能する室外熱交換器１１において、室外ファン１５によって加熱源として供給される室外空気と熱交換を行って蒸発して、低圧のガス冷媒になる。この低圧のガス冷媒は、四路切換弁１０およびアキュムレータ７を通じて、再び、圧縮機８に吸入される。暖房運転では、以上のようにして、冷媒が冷媒回路６を循環する。 The high-pressure liquid refrigerant sent to the outdoor unit 2 is decompressed to the low pressure of the refrigeration cycle in the outdoor expansion valve 12 through the liquid side shut-off valve 13, and becomes a low-pressure gas-liquid two-phase refrigerant. The low-pressure gas-liquid two-phase refrigerant reduced in pressure by the outdoor expansion valve 12 exchanges heat with outdoor air supplied as a heat source by the outdoor fan 15 in the outdoor heat exchanger 11 functioning as an evaporator of the refrigerant. And evaporate to form a low pressure gas refrigerant. The low pressure gas refrigerant is again sucked into the compressor 8 through the four-way switching valve 10 and the accumulator 7. In the heating operation, the refrigerant circulates through the refrigerant circuit 6 as described above.

　ステップＳ１０では、室内制御部７３が所定の時間条件を満たしているか否かを判断する。当該所定の時間条件としては、特に限定されないが、例えば、一日のうちの所定の時間帯であることという条件とすることができ、室内制御部７３が有するメモリ等に予め格納されている。なお、ユーザは、リモコン７４の入力部７４ｂを介して当該所定の時間条件を設定することが可能となっている。ここで、所定の時間条件を満たすと判断した場合にはステップＳ１２に移行し、所定の時間条件を満たさないと判断した場合にはステップＳ１０を繰り返す。 In step S10, the indoor control unit 73 determines whether a predetermined time condition is satisfied. The predetermined time condition is not particularly limited, but can be, for example, a condition that it is a predetermined time zone of one day, and is stored in advance in a memory or the like included in the indoor control unit 73. The user can set the predetermined time condition via the input unit 74b of the remote controller 74. Here, when it is determined that the predetermined time condition is satisfied, the process proceeds to step S12, and when it is determined that the predetermined time condition is not satisfied, step S10 is repeated.
　ステップＳ１１では、室内制御部７３が室内の照度が予め定めた所定照度以下であるか否かを判断する。具体的には、室内制御部７３は、コーナー基板６０を介して照度センサ６２が検知した照度値を把握し、当該照度値を所定照度と比較することで判断する。所定照度以下（暗い）と判断した場合にはステップＳ１２に移行し、所定照度以下ではない（暗くはない）と判断した場合にはステップＳ１０を繰り返す。 In step S11, the indoor control unit 73 determines whether the illuminance in the room is less than or equal to a predetermined illuminance. Specifically, the indoor control unit 73 determines the illuminance value detected by the illuminance sensor 62 through the corner substrate 60 and compares the illuminance value with a predetermined illuminance. If it is determined that the illuminance is lower than the predetermined illuminance (dark), the process proceeds to step S12. If it is determined that the illuminance is not lower than the predetermined illuminance (not dark), step S10 is repeated.
　ステップＳ１２では、室内制御部７３が室内に人が存在しているか否かを判断する。具体的には、室内制御部７３は、人検知センサ５５からの検知信号を受信することで、室内における人の存在の有無を判断する。人が存在すると判断した場合にはステップＳ１３に移行し、人が存在しないと判断した場合にはステップＳ１０に戻る。 In step S12, the indoor control unit 73 determines whether a person is present in the room. Specifically, the indoor control unit 73 receives the detection signal from the human detection sensor 55 to determine the presence or absence of a person in the room. If it is determined that a person is present, the process proceeds to step S13, and if it is determined that a person is not present, the process returns to step S10.
　ステップＳ１３では、室内制御部７３は、ＬＥＤ６１を発光させ、ブザー６３から警告音が発せられるように、制御を行う。具体的には、室内制御部７３は、コーナー基板６０に向けて、ＬＥＤ６１を発光させ、ブザー６３から警告音が発せられるように制御信号を送信する。これにより、当該制御信号を受信したコーナー基板６０が、ＬＥＤ６１を発光させ、ブザー６３から警告音を発せられるように、ＬＥＤ６１およびブザー６３を制御する。 In step S13, the indoor control unit 73 causes the LED 61 to emit light, and performs control such that a warning sound is emitted from the buzzer 63. Specifically, the indoor control unit 73 causes the LED 61 to emit light toward the corner substrate 60, and transmits a control signal so that a warning sound is emitted from the buzzer 63. Thereby, the corner substrate 60 that has received the control signal causes the LED 61 to emit light, and controls the LED 61 and the buzzer 63 so that the buzzer 63 emits a warning sound.
　ステップＳ１４では、室内制御部７３は、ＬＥＤ６１を発光させ、ブザー６３から警告音を発するようにしてから所定時間が経過したか否かを判断する。ここで、所定時間としては特に限定されないが、例えば、１分以上５分未満の所定の時間長さとすることができる。所定時間が経過したと判断した場合にはステップＳ１５に移行し、所定時間が経過していないと判断した場合には所定時間が経過するまでＬＥＤ６１の発光およびブザー６３からの警告音の出力を続ける。 In step S14, the indoor control unit 73 causes the LED 61 to emit light and determines whether a predetermined time has elapsed after the buzzer 63 emits a warning sound. Here, the predetermined time is not particularly limited, but can be, for example, a predetermined time length of 1 minute or more and less than 5 minutes. If it is determined that the predetermined time has elapsed, the process proceeds to step S15. If it is determined that the predetermined time has not elapsed, the light emission of the LED 61 and the output of the warning sound from the buzzer 63 are continued until the predetermined time elapses. .
　ステップＳ１５では、室内制御部７３は、ＬＥＤ６１の発光を停止させ、ブザー６３から警告音も止めて、ステップＳ１０に戻り、上記処理を繰り返す。 In step S15, the indoor control unit 73 stops the light emission of the LED 61, stops the warning sound from the buzzer 63, returns to step S10, and repeats the above process.
