A nitrogen gas generating means 2 for generating nitrogen, an air compressor 3 for sending air to the nitrogen gas generating means 2, a storage tank 50 for storing the nitrogen gas generated by the nitrogen gas generating means 2, and a control means 8. The control means 8 controls the air compressor 3 to be inactive during a predetermined time period A, and to enable the air compressor 3 during a period other than the time period A. The supply of nitrogen gas to the low oxygen chamber 30 is limited to only from the storage tank 50, and the preset low oxygen concentration of the low oxygen chamber 30 is maintained during the predetermined time period when the air compressor is not operating. A value obtained by dividing a product value obtained by multiplying the pressure of the low oxygen chamber 30 by the volume of the nitrogen gas supplied for maintaining by a predetermined pressure in the storage tank 50 that can be increased in pressure by the air compressor 3. The value exceeding the value is defined as the internal volume of the storage tank 50. The volume of the nitrogen gas to be fed means the total volume of the nitrogen gas to be fed to the low oxygen chamber 30 during the predetermined time zone A when the air compressor is not operating. The pressure of the low oxygen chamber 30 means the pressure when the target low oxygen concentration is set in the low oxygen chamber 30.
前記定めた時間帯以外の時間帯Ｂのときは、前記制御手段８が、前記貯留タンク５０内の窒素ガスを測定する圧力測定手段５１が測定した圧力が前記時間帯Ａに前記低酸素室３０に必要な窒素ガスを送給可能とするための予め定めた圧力以下のときに、前記エアーコンプレッサー３及び前記窒素ガス発生手段２を稼働させて外気から窒素ガスを分離して前記窒素ガスを前記貯留タンク５０内に送給し、前記貯留タンク５０内の窒素ガスの圧力を前記予め定めた圧力に維持する制御をする。また、前記制御手段８は、前記圧力測定手段５１が測定した圧力が予め定めた圧力超になると、前記エアーコンプレッサー３及び前記窒素ガス発生手段２の稼働を止める。 In the time period B other than the determined time period, the control unit 8 causes the pressure measured by the pressure measuring unit 51 that measures the nitrogen gas in the storage tank 50 to be the low oxygen chamber 30 during the time period A. When the pressure is equal to or lower than a predetermined pressure required to supply the nitrogen gas required for the above, the air compressor 3 and the nitrogen gas generating means 2 are operated to separate the nitrogen gas from the outside air to remove the nitrogen gas. The nitrogen gas is fed into the storage tank 50, and the pressure of the nitrogen gas in the storage tank 50 is controlled to be maintained at the predetermined pressure. Further, the control means 8 stops the operation of the air compressor 3 and the nitrogen gas generating means 2 when the pressure measured by the pressure measuring means 51 exceeds a predetermined pressure.
前記エアーコンプレッサー３は、外気を前記窒素ガス発生手段２に送り込み、前記窒素ガス発生手段２で発生させた窒素ガスを、前記貯留タンク５０に送り込み前記貯留タンク５０内に充満しつつある窒素ガスの増圧を行う。前記エアーコンプレッサー３を止めると、前記窒素ガスの前記貯留タンク５０内への送り込みが止まる。 The air compressor 3 sends the outside air to the nitrogen gas generating means 2 and sends the nitrogen gas generated by the nitrogen gas generating means 2 to the storage tank 50 to fill the storage tank 50 with the nitrogen gas. Increase pressure. When the air compressor 3 is stopped, the feeding of the nitrogen gas into the storage tank 50 is stopped.
前記エアーコンプレッサー３は、前記制御手段８により、図５に示すように予め定めた時間帯Ａのときは前記エアーコンプレッサー３を非稼働状態にして、前記時間帯Ａ以外のときの時間帯Ｂには前記エアーコンプレッサーを稼働可能状態にする制御がされる。予め定めた時間帯Ａとして、図５に示すように例えば夜２１時から翌日の朝６時までの時間帯Ａと設定すると、前記エアーコンプレッサー３は、夜２１時から翌日の朝６時までの時間帯Ａの予め定めた時間帯Ａは非稼働にし、朝６時から夜２１時までの時間帯Ｂでは稼働可能状態に制御される。 As shown in FIG. 5, the air compressor 3 sets the air compressor 3 to a non-operating state during a predetermined time zone A as shown in FIG. Is controlled to enable the air compressor. As shown in FIG. 5, for example, when the time zone A from 21:00 pm to 6:00 am the next day is set as the predetermined time zone A, the air compressor 3 operates from 21:00 pm to 6:00 am the next day. The predetermined time zone A of the time zone A is made non-operational, and the time zone B from 6:00 am to 21:00 pm is controlled to be operable.
そして、前記エアーコンプレッサー３は、例えば朝６時から夜２１時までの時間帯Ｂの稼働可能状態のときに、前記制御手段８により、前記貯留タンク５０に取り付けた前記貯留タンク５０内の窒素ガスの圧力を測定する圧力測定手段５１の測定した圧力が、前記低酸素室３０に必要な窒素ガスを送給可能とするための予め定めた圧力以下のときに稼働し、前記貯留タンク５０内の窒素ガスの圧力が前記予め定めた圧力に到達すると停止する。これにより、前記稼働状態のときに前記貯留タンク５０内の窒素ガスの圧力が前記予め定めた圧力に維持される。 Then, when the air compressor 3 is in an operable state in a time zone B from 6 am to 21:00 pm, for example, the nitrogen gas in the storage tank 50 attached to the storage tank 50 is controlled by the control means 8. When the pressure measured by the pressure measuring means 51 for measuring the pressure of the storage tank 50 is equal to or lower than a predetermined pressure for supplying the necessary nitrogen gas to the low oxygen chamber 30, It stops when the pressure of the nitrogen gas reaches the predetermined pressure. Thereby, the pressure of the nitrogen gas in the storage tank 50 is maintained at the predetermined pressure in the operating state.
前記時間帯Ｂのときに前記貯留タンク５０内に予め定めた圧力の窒素ガスが充満して貯留されると、前記時間帯Ａのときに低酸素室３０に送給するために必要な窒素ガス量が確保された状態となる。そして、前記時間帯Ａのときには、制御手段８により、低酸素室３０に設けた酸素濃度測定手段１０により測定した酸素濃度が予め定めた低酸素濃度を超えた場合に前記貯留タンク５０内の窒素ガスが低酸素室３０に送給される。 When nitrogen gas having a predetermined pressure is filled and stored in the storage tank 50 during the time period B, the nitrogen gas necessary for sending to the low oxygen chamber 30 during the time period A. The quantity is secured. Then, during the time period A, when the oxygen concentration measured by the oxygen concentration measuring unit 10 provided in the low oxygen chamber 30 by the control unit 8 exceeds a predetermined low oxygen concentration, the nitrogen in the storage tank 50 is reduced. Gas is delivered to the low oxygen chamber 30.
前記窒素ガス発生手段２は、外気から窒素ガスと酸素を分離する手段であり、例えば、空気を送り込み、膜を通過しなかった窒素を取り出す膜分離方式の装置、又は、空気から吸着材で酸素と窒素ガスを分離するＰＳＡ方式の装置などがあり、いずれの窒素ガス発生装置でもよい。これらの窒素ガス発生装置は一般的に約９９％の窒素ガス濃度の窒素ガスを発生させることができ、前記窒素ガス発生器としては空気から窒素ガスと酸素とを分離させることができるものであればよい。 The nitrogen gas generating means 2 is means for separating nitrogen gas and oxygen from the outside air, for example, a device of a membrane separation system for feeding in air to take out nitrogen that has not passed through the membrane, or oxygen from the air by an adsorbent. There is a PSA type device for separating the nitrogen gas and the nitrogen gas, and any nitrogen gas generator may be used. Generally, these nitrogen gas generators can generate nitrogen gas having a nitrogen gas concentration of about 99%, and the nitrogen gas generator should be capable of separating nitrogen gas and oxygen from air. Good.
前記窒素ガス発生手段２で発生させた窒素ガスは、配管１３ｂを介して前記貯留タンク５０に送給される。 The nitrogen gas generated by the nitrogen gas generating means 2 is sent to the storage tank 50 via the pipe 13b.
前記貯留タンク５０は、前記エアーコンプレッサー３が稼働状態に制御されている時間帯Ｂに、前記窒素ガス発生手段２で発生させ送り込まれた窒素ガスを貯留し、前記時間帯Ａになる直前の前記時間帯Ｂの瞬間においては貯留される窒素ガス量は少なくとも、前記エアーコンプレッサー非稼働状態の前記定めた時間帯Ａに前記低酸素室３０の予め設定した低酸素濃度を維持するために送給されるべき窒素ガス量を超える窒素ガス量である。 The storage tank 50 stores the nitrogen gas generated and sent by the nitrogen gas generating means 2 in a time zone B in which the air compressor 3 is controlled to be in an operating state, and the storage tank 50 is in a state just before the time zone A. At the moment of the time zone B, at least the amount of stored nitrogen gas is sent to maintain the preset low oxygen concentration of the low oxygen chamber 30 during the predetermined time zone A when the air compressor is not operating. The amount of nitrogen gas exceeds the amount of nitrogen gas that should be used.
よって、前記貯留タンク５０の内容積は、前記エアーコンプレッサー非稼働状態の前記定めた時間帯に、前記低酸素室３０の予め設定した低酸素濃度を維持するために送給する窒素ガスの体積に前記低酸素室３０の圧力を乗じた乗算値を、前記エアーコンプレッサー３で増圧可能な前記貯留タンク５０内の予め設定した圧力で除した値を超える値にする。また、前記貯留タンク５０内の予め設定した圧力は、前記制御手段８の中の記憶部に記憶される。 Therefore, the internal volume of the storage tank 50 is equal to the volume of nitrogen gas that is fed to maintain the preset low oxygen concentration in the low oxygen chamber 30 during the predetermined time period when the air compressor is not operating. The multiplication value obtained by multiplying the pressure in the low oxygen chamber 30 is set to a value that exceeds a value obtained by dividing by a preset pressure in the storage tank 50 that can be increased in pressure by the air compressor 3. Further, the preset pressure in the storage tank 50 is stored in the storage unit in the control means 8.
前記貯留タンク５０への窒素ガスの送り込みについては、前記制御手段８は、前記貯留タンク５０内の窒素ガスを測定する圧力測定手段５１が測定した圧力が前記貯留タンク５０内の予め設定した圧力以下のときに、前記エアーコンプレッサー３及び前記窒素ガス発生手段２を稼働させて外気から窒素ガスを分離して前記窒素ガスを前記貯留タンク５０内に送給し、一方前記圧力測定手段５１が測定した圧力が前記貯留タンク５０内の予め設定した圧力に到達すると前記エアーコンプレッサー３及び前記窒素ガス発生手段２を稼働停止させる制御をし、前記貯留タンク５０内の窒素ガスの圧力を前記予め定めた圧力に維持する制御をする。 Regarding the feeding of the nitrogen gas into the storage tank 50, the control means 8 controls the pressure measured by the pressure measuring means 51 for measuring the nitrogen gas in the storage tank 50 to be equal to or lower than the preset pressure in the storage tank 50. At this time, the air compressor 3 and the nitrogen gas generating means 2 are operated to separate the nitrogen gas from the outside air and feed the nitrogen gas into the storage tank 50, while the pressure measuring means 51 measures. When the pressure reaches a preset pressure in the storage tank 50, control is performed to stop the operation of the air compressor 3 and the nitrogen gas generating means 2, and the pressure of the nitrogen gas in the storage tank 50 is set to the predetermined pressure. Control to maintain.

前記空調機７は、低酸素室３０内の気温調整及び室内の空気を循環させる機器である。前記空調機７は、前記低酸素室３０へは、窒素ガス又は酸素が別々に送り込まれてくるので、窒素ガス又は酸素が低酸素室３０内の偏った範囲に存しないように低酸素室３０内の空気を常時循環させる役目がある。よって、低酸素室３０内の空気の酸素濃度、窒素ガス濃度及び炭酸ガス濃度の均一化を図っている。 The air conditioner 7 is a device for adjusting the temperature in the low oxygen chamber 30 and circulating the air in the room. In the air conditioner 7, since nitrogen gas or oxygen is separately sent to the low oxygen chamber 30, the low oxygen chamber 30 is kept so that the nitrogen gas or oxygen does not exist in a biased range in the low oxygen chamber 30. It has the role of constantly circulating the air inside. Therefore, the oxygen concentration, the nitrogen gas concentration, and the carbon dioxide concentration of the air in the low oxygen chamber 30 are made uniform.
前記制御手段８は、制御線９で前記酸素濃度測定手段１０、前記炭酸ガス濃度測定手段１１、前記窒素ガス濃度測定手段１２、前記窒素ガス発生手段２、前記エアーコンプレッサー３、前記流量調整弁４、前記排気手段５、前記送風手段６、前記空調機７、窒素ガスストップ弁１７と接続されており、図１又は図２に示すように前記酸素タンク１５を備えた場合はさらに酸素ストップ弁１６及び三方切換弁１９と接続されている。 The control means 8 controls the oxygen concentration measuring means 10, the carbon dioxide gas concentration measuring means 11, the nitrogen gas concentration measuring means 12, the nitrogen gas generating means 2, the air compressor 3, and the flow rate adjusting valve 4 through a control line 9. , The exhaust means 5, the blower means 6, the air conditioner 7, and the nitrogen gas stop valve 17, and when the oxygen tank 15 is provided as shown in FIG. 1 or 2, further oxygen stop valve 16 is provided. And the three-way switching valve 19.
そして、前記制御手段８は、前記酸素濃度測定手段１０からの酸素濃度情報、前記炭酸ガス濃度測定手段１１からの炭酸ガス濃度情報、前記窒素ガス濃度測定手段１２からの窒素ガス濃度情報を取得して、前記窒素ガス発生手段２、前記エアーコンプレッサー３、前記流量調整弁４、前記窒素ガスストップ弁１７、前記排気手段５、前記送風手段６及び前記空調機７の稼働を制御する。前記酸素タンク１５を備える場合は、さらに前記酸素ストップ弁１６及び前記三方切換弁１９の動作も制御する。 Then, the control means 8 acquires the oxygen concentration information from the oxygen concentration measuring means 10, the carbon dioxide concentration information from the carbon dioxide concentration measuring means 11, and the nitrogen gas concentration information from the nitrogen gas concentration measuring means 12. The operation of the nitrogen gas generating means 2, the air compressor 3, the flow rate adjusting valve 4, the nitrogen gas stop valve 17, the exhausting means 5, the blowing means 6 and the air conditioner 7 is controlled. When the oxygen tank 15 is provided, the operations of the oxygen stop valve 16 and the three-way switching valve 19 are also controlled.
次に、前記低酸素環境制御システム１は、例えば図５に示すように２１時から６時までの予め設定された時間帯Ａではなく、６時から２１時までの他の時間帯Ｂであるときに、前記制御手段８により、前記低酸素室３０の室内の酸素濃度を予め定めた低酸素濃度に低下させるときは、エアーコンプレッサー３を稼働させることが可能であることから、前記酸素濃度測定手段１０からの酸素濃度情報が予め定めた酸素濃度になるまで、前記エアーコンプレッサー３及び前記窒素ガス発生手段２を稼働させて前記窒素ガスを前記貯留タンク５０内に貯留させて、前記貯留タンク５０内に貯留されている窒素ガスを、窒素ガスストップ弁１７を開にし前記流量調整弁４で窒素ガスの流量を調整して前記低酸素室３０の室内に送給し、前記排気手段５及び前記送風手段６をＯＦＦさせ、前記空調機７により室内の空気を循環させる制御をする。これにより、低酸素室３０の室内の酸素濃度を予め定めた低酸素濃度にする。 Next, the low oxygen environment control system 1 is not the preset time zone A from 21:00 to 6:00 as shown in FIG. 5, for example, but is another time zone B from 6:00 to 21:00. At this time, when the control means 8 lowers the oxygen concentration in the low oxygen chamber 30 to a predetermined low oxygen concentration, the air compressor 3 can be operated. The air compressor 3 and the nitrogen gas generating means 2 are operated to store the nitrogen gas in the storage tank 50 until the oxygen concentration information from the means 10 reaches a predetermined oxygen concentration. The nitrogen gas stored inside is supplied to the inside of the low oxygen chamber 30 by opening the nitrogen gas stop valve 17 and adjusting the flow rate of the nitrogen gas with the flow rate adjusting valve 4, and the exhaust means 5 and the above The air blower 6 is turned off, and the air conditioner 7 controls the circulation of the indoor air. As a result, the oxygen concentration in the low oxygen chamber 30 becomes a predetermined low oxygen concentration.
予め設定された時間帯Ａであるときには、エアーコンプレッサー３を稼働させないので、前記低酸素室３０の室内の酸素濃度を予め定めた低酸素濃度に低下させるときは、前記酸素濃度測定手段１０からの酸素濃度情報が予め定めた酸素濃度になるまで、制御手段８により、窒素ガスストップ弁１７を開にし、前記流量調整弁４の窒素ガス量の調整をしながら前記貯留タンク５０内に貯留されている窒素ガスを前記低酸素室３０の室内に送給し、前記排気手段５及び前記送風手段６をＯＦＦさせ、前記空調機７により室内の空気を循環させる制御をする。なお、三方切換弁１９を設けた場合は三方切換弁１９を窒素ガス側に切り換える。これにより、低酸素室３０の室内の酸素濃度を予め定めた低酸素濃度にする。 During the preset time zone A, the air compressor 3 is not operated. Therefore, when lowering the oxygen concentration in the low oxygen chamber 30 to a predetermined low oxygen concentration, the oxygen concentration measuring means 10 is operated. Until the oxygen concentration information reaches a predetermined oxygen concentration, the control means 8 opens the nitrogen gas stop valve 17 to store the nitrogen gas in the storage tank 50 while adjusting the nitrogen gas amount of the flow rate adjusting valve 4. The nitrogen gas is fed into the low oxygen chamber 30, the exhaust means 5 and the blowing means 6 are turned off, and the air conditioner 7 circulates the air in the room. When the three-way switching valve 19 is provided, the three-way switching valve 19 is switched to the nitrogen gas side. As a result, the oxygen concentration in the low oxygen chamber 30 becomes a predetermined low oxygen concentration.
前記窒素ガス発生手段２から発生する窒素ガス濃度は９９％レベルである。前記低酸素室３０の室内の前記酸素濃度測定手段１０による酸素濃度情報の酸素濃度が予め定めた低酸素濃度に到達すると、制御手段８は、前記窒素ガスストップ弁１７を閉にして前記貯留タンク５０からの窒素ガスの送給を停止し、前記空調機７により室内の空気を循環させる制御をする。なお、前記酸素濃度測定手段１０とともに窒素ガス測定手段１２で窒素ガス濃度を併用して使用し測定してもよい。 The nitrogen gas concentration generated from the nitrogen gas generating means 2 is at the 99% level. When the oxygen concentration of the oxygen concentration measuring means 10 in the low oxygen chamber 30 reaches a predetermined low oxygen concentration, the control means 8 closes the nitrogen gas stop valve 17 and stores the storage tank. The supply of the nitrogen gas from 50 is stopped, and the air in the room is circulated by the air conditioner 7. The oxygen concentration measuring means 10 and the nitrogen gas measuring means 12 may be used together to measure the nitrogen gas concentration.
次に、前記酸素濃度情報の酸素濃度が予め定めた酸素濃度から上下に変動したときは、予め定めた酸素濃度になるまで、制御手段８は、前記窒素ガスストップ弁１７を開閉し、前記流量調整弁４により窒素ガスの流量を調整し、室内空気の排気をする前記排気手段５をＯＮ−ＯＦＦ制御し、外気を送給する前記送風手段６をＯＮ−ＯＦＦ制御し、前記空調機７で室内の空気を循環させる制御をする。また、酸素タンク１５を設けた場合は、前記制御手段８は、酸素ストップ弁１６の開閉、及び前記三方切換弁１９の切換の制御を行う。 Next, when the oxygen concentration of the oxygen concentration information fluctuates up and down from the predetermined oxygen concentration, the control means 8 opens and closes the nitrogen gas stop valve 17 until the oxygen concentration reaches the predetermined oxygen concentration, The flow rate of nitrogen gas is adjusted by the adjusting valve 4, the exhaust means 5 for exhausting the indoor air is ON-OFF controlled, the blower means 6 for feeding the outside air is ON-OFF controlled, and the air conditioner 7 is used. Control the circulation of indoor air. When the oxygen tank 15 is provided, the control means 8 controls opening/closing of the oxygen stop valve 16 and switching of the three-way switching valve 19.
低酸素室３０の扉２０からのトレーニング者の出入り、トレーニング者の酸素の使用量、前記送風手段６により外気すなわち酸素の室内への取り入れなどにより、低酸素室３０内の酸素濃度や窒素ガス濃度は変動する。例えば、酸素濃度測定手段１０で測定した酸素濃度が予め定めた酸素濃度より低下したときは、制御手段８により、前記窒素ガスストップ弁１７を閉にして前記流量調整弁４を絞って窒素ガスの送給を停止させ、室内空気の排気をする前記排気手段５をＯＮさせ、外気を取り入れる前記送風手段６をＯＮさせ、前記空調機７をＯＮさせて室内の空気を循環させる制御をする。これにより、人体にとって必要な酸素濃度にすることができる。 The oxygen concentration and the nitrogen gas concentration in the low oxygen chamber 30 are determined by the entrance and exit of the trainee through the door 20 of the low oxygen chamber 30, the amount of oxygen used by the trainee, and the intake of outside air, that is, oxygen by the blower 6 into the room. Fluctuates. For example, when the oxygen concentration measured by the oxygen concentration measuring means 10 is lower than a predetermined oxygen concentration, the control means 8 closes the nitrogen gas stop valve 17 and throttles the flow rate adjusting valve 4 to remove the nitrogen gas. The air supply is stopped, the exhaust means 5 for exhausting indoor air is turned on, the blower means 6 for taking in outside air is turned on, and the air conditioner 7 is turned on to circulate indoor air. Thereby, the oxygen concentration required for the human body can be obtained.
さらに、酸素濃度測定手段１０で測定した酸素濃度が予め定めた酸素濃度を大きく急に下回ったときは、図１又は図２に示すように、前記窒素ガス発生手段２により分離された酸素を貯留する酸素タンク１５と、前記酸素タンク１５から前記流量調整弁４との間の配管１４ｂに設けた酸素ストップ弁１６と、前記低酸素室３０につながる配管１８と前記配管１４ｂとの合流点に設けた三方切替弁１９と、を備えて、前記制御手段８により、前記窒素ガスストップ弁１７を閉にして前記貯留タンク５０からの窒素ガスの送給を停止し、前記酸素ストップ弁１６を開にして前記酸素タンク１５からの酸素の送給を開始し、前記三方切換弁１９を配管１４ｂ側のみ開にして酸素のみを流動可能にし、前記排気手段５、前記送風手段６及び前記空調機７をＯＮさせて稼働させる制御を実施する。これにより、万一大幅な酸素濃度低下時になっても早急に短時間で酸素濃度を増加させることができ、人体にとって安全な環境をつくることができる。 Further, when the oxygen concentration measured by the oxygen concentration measuring means 10 falls sharply below a predetermined oxygen concentration, the oxygen separated by the nitrogen gas generating means 2 is stored as shown in FIG. 1 or 2. The oxygen tank 15 that operates, the oxygen stop valve 16 provided in the pipe 14b between the oxygen tank 15 and the flow rate adjustment valve 4, and the pipe 18 connected to the low oxygen chamber 30 and the pipe 14b And a three-way switching valve 19, and the control means 8 closes the nitrogen gas stop valve 17 to stop the supply of nitrogen gas from the storage tank 50 and opens the oxygen stop valve 16. Then, the supply of oxygen from the oxygen tank 15 is started, the three-way switching valve 19 is opened only on the side of the pipe 14b to allow only oxygen to flow, and the exhaust means 5, the blower means 6 and the air conditioner 7 are connected.

As a result, the oxygen concentration can be increased quickly in a short time even if the oxygen concentration is drastically reduced, and a safe environment for the human body can be created.
また、酸素濃度測定手段１０で測定した酸素濃度が予め定めた酸素濃度より増加したときは、制御手段８により、前記窒素ガスストップ弁１７を開にして、前記三方切換弁１９を設けた場合は前記三方切換弁１９を前記貯留タンク５０からの窒素ガスのみを流動可能に切換えて、前記流量調整弁４により窒素ガスの流量を増加させ、低酸素室３０の室内空気の排気をする前記排気手段５をＯＮさせ、外気を取り入れる前記送風手段６をＯＦＦさせ、前記空調機７で室内の空気を循環させる制御をする。これにより、低酸素室３０の室内の酸素濃度を予め定めた酸素濃度にすることができる。 Further, when the oxygen concentration measured by the oxygen concentration measuring means 10 is higher than a predetermined oxygen concentration, the control means 8 opens the nitrogen gas stop valve 17 to provide the three-way switching valve 19 The exhaust means for switching the three-way switching valve 19 so that only the nitrogen gas from the storage tank 50 can flow and increasing the flow rate of the nitrogen gas by the flow rate adjusting valve 4 to exhaust the indoor air in the low oxygen chamber 30. 5 is turned on, the blower means 6 for taking in outside air is turned off, and the air conditioner 7 controls the circulation of the indoor air. Thereby, the oxygen concentration in the low oxygen chamber 30 can be set to a predetermined oxygen concentration.
次に、低酸素室３０内の炭酸ガス濃度測定手段１１が測定した炭酸ガス濃度が予め定めた炭酸ガス濃度を超えたときには、トレーニング中等の人体に悪影響が生ずるのを未然に防止するため、早期に低酸素室３０内の空気を排出し外気と入れ替えるために、前記制御手段８により、前記貯留タンク５０からの窒素ガスの送給を前記窒素ガスストップ弁１７を閉にして停止させ、前記流量調整弁４を絞って、これ以上酸素濃度が低下するのを防止し、前記排気手段５をＯＮにして室内の濃度が高い炭酸ガスを含む空気を排気し、前記送風手段６をＯＮにして外気を取り入れる。そして、人体に異常となる炭酸ガス濃度の空気を前記低酸素室３０内において偏らせないようにするために前記空調機７をＯＮにして室内の空気を循環させる制御をする。なお、酸素タンク１５を設けた場合には、前記制御手段８により、さらに酸素ストップ弁１６を閉にし、三方切換弁１９はそのままとし、流量調整弁４が絞る制御を行う。これにより、低酸素室３０の室内の炭酸ガス濃度を予め定めた炭酸ガス濃度にすることができる。 Next, when the carbon dioxide gas concentration measured by the carbon dioxide gas concentration measuring means 11 in the low oxygen chamber 30 exceeds a predetermined carbon dioxide gas concentration, it is possible to prevent the human body from being adversely affected during training or the like. In order to discharge the air in the low oxygen chamber 30 and replace it with the outside air, the control means 8 stops the feeding of the nitrogen gas from the storage tank 50 by closing the nitrogen gas stop valve 17 and stopping the flow rate. The regulating valve 4 is throttled to prevent the oxygen concentration from further decreasing, the exhaust means 5 is turned on to exhaust the air containing carbon dioxide gas having a high concentration in the room, and the blower means 6 is turned on to open the outside air. Take in. Then, the air conditioner 7 is turned on to circulate the air in the room in order to prevent the air having a carbon dioxide concentration which is abnormal to the human body from being biased in the low oxygen room 30. When the oxygen tank 15 is provided, the control means 8 further closes the oxygen stop valve 16, leaves the three-way switching valve 19 as it is, and controls the flow rate adjusting valve 4 to throttle. Thereby, the carbon dioxide concentration in the low oxygen chamber 30 can be set to a predetermined carbon dioxide concentration.
また、低酸素室３０内の炭酸ガス濃度が高くなるのを抑制させるために、前記低酸素室３０内に炭酸ガス除去手段２１を備えてもよい。前記炭酸ガス除去手段２１として例えば炭酸ガス吸着剤がある。炭酸ガスが低酸素室３０内に充満するのを抑制するため省エネ効果が期待できる。 Further, in order to suppress an increase in carbon dioxide concentration in the low oxygen chamber 30, a carbon dioxide removing means 21 may be provided in the low oxygen chamber 30.
