基于上述，本发明提供的室内环境控制机组，在使用过程中，可将第一进风口和第二出风口与室外连通，将第一出风口和第二进风口与室内连通。当室内的空气需要进行更新且室内需要的冷热负荷可以通过室外新风来满足时，可关闭第三控制阀和第四控制阀并打开第一控制阀和第二控制阀，同时开启第一风机和第二风机，此时，室外新风可以通过第一进风口进入进风通道，经过直流通道后由第一出风口流入室内，同时，室内空气则由第二进风口流入排风通道，经所述直排通道后由第二出风口排出室外，由此使室内空气得到更新。当直流通道中供给的冷热负荷超过室内需求时，可开启第三控制阀和第四控制阀，此时一部分室外新风通过直流通道流向第一出风口，一部分室外新风由第三进风口进入热回收装置中的第一通道，同时一部分室内空气通过直排通道流向第二出风口，一部分室内空气由第四进风口进入热回收装置中的第二通道，由于流经第一通道和第二通道的空气会进行热量传递，从而使第一通道中的室外新风和第二通道中的室内空气之间的实现热量传递，进而调整了经过第一通道流向第一出风口的室外新风的温度，经过直流通道的室外新风和经过第一通道的室外新风混合后由第一出风口流入室内，经过直排通道的室内空气和经过第二通道的室内空气由第二出风口排出室外，由于流入室内的室外新风的温度能够得到调整，因此在更新室内空气的同时利于满足室内需要的冷热负荷，可通过调整第一控制阀、第二控制阀、第三控制阀和第四控制阀的开度来调整经过直流通道、直排通道、第一通道和第二通道的风量比例，由此使流入室内的室外新风的温度能够满足室内需要的冷热负荷。当调整第一控制阀、第二控制阀、第三控制阀和第四控制阀的开度仍不能够满足室内需要的冷热负荷时，可将第一控制阀和第二控制阀关闭，并将第三控制阀和第四控制阀开启，由此使流入室内的室外新风的温度够得到最大程度的调整，以满足室内需要的冷热负荷。由此本发明提供的室内环境控制机组能够在更新室内空气、保证空气品质的同时起到调整室内温度的作用，减少了空调、暖气等传统制冷或采暖设备的使用，提高了调节性及灵活性，节约了能源。当将第一控制阀和第二控制阀关闭，并将第三控制阀和第四控制阀开启后仍不能满足室内需要的冷热负荷时，可在第一控制阀和第二控制阀关闭且第三控制阀和第四控制阀开启的状态下，同时开启热泵空调装置，通过内部换热器来调整流入室内的室外新风的温度，以满足室内需要的冷热负荷，由于热回收换热器设置在所述排风通道中，且相对于所述直排通道和所述第四出风口更靠近所述第二出风口设置，因此由第四出风口排出的空气会经过热回收换热器与热回收换热器进行热交换，由于第四出风口排出的空气的温度会介于室外温度和室内温度之间，因此更利于热回收换热器散热或吸热，进而能够提高热泵空调装置的制冷、制热效率，降低室内环境系统能耗。另外，由于热回收换热器与外部换热器并联，因此，可以有效避免由于排风通道中温度的改变，热回收换热器不能满足热泵空调装置散热或吸热要求的情况，提高了热泵空调装置使用的可靠性。Based on the above, the indoor environment control unit provided by the present invention can communicate the first air inlet and the second air outlet with the outdoor, and connect the first air outlet and the second air inlet with the indoor during use. When the indoor air needs to be renewed and the indoor cooling and heating load can be met by outdoor fresh air, the third control valve and the fourth control valve can be closed, the first control valve and the second control valve can be opened, and the first fan can be turned on at the same time and the second fan. At this time, the outdoor fresh air can enter the air inlet channel through the first air inlet, and flow into the room from the first air outlet after passing through the direct current channel. At the same time, the indoor air flows into the exhaust channel from the second air inlet. The air in the room is refreshed through the second air outlet after being exhausted from the above-mentioned in-line channel. When the cooling and heating load supplied in the direct current passage exceeds the indoor demand, the third control valve and the fourth control valve can be opened. At this time, part of the outdoor fresh air flows to the first air outlet through the direct current passage, and part of the outdoor fresh air enters the heat recovery through the third air inlet. At the same time, part of the indoor air flows to the second air outlet through the straight discharge channel, and part of the indoor air enters the second channel in the heat recovery device from the fourth air inlet. The air will conduct heat transfer, so that the heat transfer between the outdoor fresh air in the first channel and the indoor air in the second channel is realized, and then the temperature of the outdoor fresh air flowing through the first channel to the first air outlet is adjusted. The outdoor fresh air in the channel and the outdoor fresh air passing through the first channel are mixed and then flow into the room through the first air outlet. The temperature of the fresh air can be adjusted, so while updating the indoor air, it is beneficial to meet the cooling and heating loads required in the room, which can be adjusted by adjusting the opening degrees of the first control valve, the second control valve, the third control valve and the fourth control valve The ratio of the air volume passing through the direct flow channel, the straight discharge channel, the first channel and the second channel, so that the temperature of the outdoor fresh air flowing into the room can meet the cooling and heating load required by the room. When adjusting the opening degrees of the first control valve, the second control valve, the third control valve and the fourth control valve still cannot meet the cooling and heating load required in the room, the first control valve and the second control valve can be closed, and The third control valve and the fourth control valve are opened, so that the temperature of the outdoor fresh air flowing into the room can be adjusted to the greatest extent, so as to meet the cooling and heating load required by the room. Therefore, the indoor environment control unit provided by the present invention can adjust the indoor temperature while updating the indoor air and ensuring the air quality, reducing the use of traditional cooling or heating equipment such as air conditioners and heaters, and improving the adjustability and flexibility , saving energy. When the first control valve and the second control valve are closed, and the third control valve and the fourth control valve are opened, and the cooling and heating load required in the room cannot be met, the first control valve and the second control valve can be closed and When the third control valve and the fourth control valve are opened, the heat pump air conditioner is turned on at the same time, and the temperature of the outdoor fresh air flowing into the room is adjusted through the internal heat exchanger to meet the cooling and heating load required in the room. Due to the heat recovery heat exchanger It is arranged in the air exhaust channel and is arranged closer to the second air outlet than the straight exhaust channel and the fourth air outlet, so the air discharged from the fourth air outlet will pass through the heat recovery heat exchanger Exchange heat with the heat recovery heat exchanger. Since the temperature of the air discharged from the fourth air outlet will be between the outdoor temperature and the indoor temperature, it is more conducive to heat dissipation or heat absorption by the heat recovery heat exchanger, thereby improving the performance of the heat pump air conditioner. Excellent cooling and heating efficiency, reducing the energy consumption of the indoor environment system. In addition, since the heat recovery heat exchanger is connected in parallel with the external heat exchanger, it can effectively avoid the situation that the heat recovery heat exchanger cannot meet the heat dissipation or heat absorption requirements of the heat pump air conditioner due to the temperature change in the exhaust air passage, which improves the performance of the heat pump. The reliability of the air-conditioning unit.

本实施例中，在使用时，可将第一进风口102和第二出风口109与室外连通，将第一出风口103和第二进风口108与室内连通。当室内的空气需要进行更新且室内需要的冷热负荷可以通过室外新风来满足时，可关闭第三控制阀114和第四控制阀115并打开第一控制阀105和第二控制阀111，同时开启第一风机106和第二风机112，以使室外新风可以通过第一进风口102进入进风通道101，经过直流通道104后由第一出风口103流入室内，同时，室内空气则由第二进风口108流入排风通道107，经所述直排通道110后由第二出风口109排出室外，由此使室内空气得到更新。In this embodiment, when in use, the first air inlet 102 and the second air outlet 109 can be communicated with the outdoor, and the first air outlet 103 and the second air inlet 108 can be communicated with the indoor. When the indoor air needs to be renewed and the indoor cooling and heating load can be met by outdoor fresh air, the third control valve 114 and the fourth control valve 115 can be closed and the first control valve 105 and the second control valve 111 can be opened, and at the same time Turn on the first fan 106 and the second fan 112, so that the outdoor fresh air can enter the air inlet channel 101 through the first air inlet 102, and flow into the room through the first air outlet 103 after passing through the direct current channel 104; The air inlet 108 flows into the air exhaust channel 107, and is discharged outside through the second air outlet 109 after passing through the straight exhaust channel 110, thereby renewing the indoor air.
当直流通道104中供给的冷热负荷超过室内需求时，可开启第三控制阀114和第四控制阀115，以使一部分室外新风通过直流通道104流向第一出风口103，一部分室外新风由第三进风口116进入热回收装置113中的第一通道，同时一部分室内空气通过直排通道110流向第二出风口109，一部分室内空气由第四进风口118进入热回收装置113中的第二通道，由于流经热回收装置113的第一通道和第二通道的空气会进行热量传递，从而使第一通道中的室外新风和第二通道中的室内空气之间的实现热量传递，进而调整了经过第一通道流向第一出风口103的室外新风的温度，经过直流通道104的室外新风和经过第一通道的室外新风混合后由第一出风口103流入室内，经过直排通道110的室内空气和经过第二通道的室内空气由第二出风口109排出室外，由于流入室内的室外新风的温度能够得到调整，因此在更新室内空气的同时利于满足室内需要的冷热负荷，可通过调整第一控制阀105、第二控制阀111、第三控制阀114和第四控制阀115的开度来调整经过直流通道104、直排通道110、第一通道和第二通道的风量比例，由此使流入室内的室外新风的温度能够满足室内需要的冷热负荷。When the cooling and heating load supplied in the direct current channel 104 exceeds the indoor demand, the third control valve 114 and the fourth control valve 115 can be opened, so that part of the outdoor fresh air flows to the first air outlet 103 through the direct current channel 104, and part of the outdoor fresh air is passed through the first air outlet. The three air inlets 116 enter the first passage in the heat recovery device 113, while part of the indoor air flows to the second air outlet 109 through the straight discharge passage 110, and part of the indoor air enters the second passage in the heat recovery device 113 through the fourth air inlet 118 , because the air flowing through the first channel and the second channel of the heat recovery device 113 will conduct heat transfer, so that the heat transfer between the outdoor fresh air in the first channel and the indoor air in the second channel is realized, and then the The temperature of the outdoor fresh air flowing through the first channel to the first air outlet 103, the outdoor fresh air passing through the direct current channel 104 and the outdoor fresh air passing through the first channel are mixed and then flowed into the room from the first air outlet 103, and the indoor air passing through the direct discharge channel 110 And the indoor air passing through the second channel is discharged outside through the second air outlet 109. Since the temperature of the outdoor fresh air flowing into the room can be adjusted, it is beneficial to meet the indoor cooling and heating load while updating the indoor air.

Heat load, since the heat recovery heat exchanger 124 is arranged in the exhaust passage 107, and is arranged closer to the second air outlet 109 relative to the straight discharge passage 110 and the fourth air outlet 119, so by The air discharged from the fourth air outlet 119 will pass through the heat recovery heat exchanger 124 to exchange heat with the heat recovery heat exchanger 124. Since the temperature of the air discharged from the fourth air outlet 119 will be between the outdoor temperature and the indoor temperature, therefore It is more conducive to the heat dissipation or heat absorption of the heat recovery heat exchanger 124, thereby improving the cooling and heating efficiency of the heat pump air conditioner, and reducing the energy consumption of the indoor environment system. In addition, since the heat recovery heat exchanger 124 is connected in parallel with the external heat exchanger 125, it can effectively avoid the situation that the heat recovery heat exchanger 124 cannot meet the heat dissipation or heat absorption requirements of the heat pump air conditioner due to the temperature change in the exhaust air passage 107 , Improve the reliability of the use of the heat pump air conditioner.

本实施例中，当室内的空气需要进行更新且室内需要的冷热负荷可以通过室外新风来满足时，可关闭第三控制阀114和第四控制阀115并打开第一控制阀105和第二控制阀111，同时开启第一风机106和第二风机112，此时，室外新风可以通过第一进风口102进入进风通道101，经过直流通道104后由第一出风口103流入室内，同时，室内空气则由第二进风口108流入排风通道107，经所述直排通道110后由第二出风口109排出室外，由此使室内空气得到更新。当直流通道104中供给的冷热负荷超过室内需求时，可开启第三控制阀114和第四控制阀115，此时一部分室外新风通过直流通道104流向第一出风口103，一部分室外新风由第三进风口116进入热回收装置113中的第一通道，同时一部分室内空气通过直排通道110流向第二出风口109，一部分室内空气由第四进风口118进入热回收装置113中的第二通道，由于流经第一通道和第二通道的空气会进行热量传递，从而使第一通道中的室外新风和第二通道中的室内空气之间的实现热量传递，进而调整了经过第一通道流向第一出风口103的室外新风的温度，经过直流通道104的室外新风和经过第一通道的室外新风混合后由第一出风口103流入室内，经过直排通道110的室内空气和经过第二通道的室内空气由第二出风口109排出室外，由于流入室内的室外新风的温度能够得到调整，因此在更新室内空气的同时利于满足室内需要的冷热负荷，可通过调整第一控制阀105、第二控制阀111、第三控制阀114和第四控制阀115的开度来调整经过直流通道104、直排通道110、第一通道和第二通道的风量比例，由此使流入室内的室外新风的温度能够满足室内需要的冷热负荷。当调整第一控制阀105、第二控制阀111、第三控制阀114和第四控制阀115的开度仍不能够满足室内需要的冷热负荷时，可将第一控制阀105和第二控制阀111关闭，并将第三控制阀114和第四控制阀115开启，由此使流入室内的室外新风的温度够得到最大程度的调整，以满足室内需要的冷热负荷。由此本实施例中的室内环境控制机组能够在更新室内空气、保证空气品质的同时起到调整室内温度的作用，减少了空调、暖气等传统制冷或采暖设备的使用，提高了调节性及灵活性，节约了能源。当将第一控制阀105和第二控制阀111关闭，并将第三控制阀114和第四控制阀115开启后仍不能满足室内需要的冷热负荷时，可在第一控制阀105和第二控制阀111关闭且第三控制阀114和第四控制阀115开启的状态下，同时开启热泵空调装置120，通过内部换热器123来调整流入室内的室外新风的温度，以满足室内需要的冷热负荷，由于热回收换热器124设置在所述排风通道107中，且相对于所述直排通道110和所述第四出风口119更靠近所述第二出风口109设置，因此由第四出风口119排出的空气会经过热回收换热器124与热回收换热器124进行热交换，由于第四出风口119排出的空气的温度会介于室外温度和室内温度之间，因此更利于热回收换热器124散热或吸热，进而能够提高热泵空调装置120的制冷、制热效率，降低室内环境系统能耗。另外，由于热回收换热器124与外部换热器125并联，因此，可以有效避免由于排风通道107中温度的改变，热回收换热器124不能满足热泵空调装置120散热或吸热要求的情况，提高了热泵空调装置120使用的可靠性。In this embodiment, when the indoor air needs to be renewed and the indoor cooling and heating load can be met by outdoor fresh air, the third control valve 114 and the fourth control valve 115 can be closed and the first control valve 105 and the second control valve 105 can be opened. Control the valve 111, open the first fan 106 and the second fan 112 at the same time, at this time, the outdoor fresh air can enter the air inlet passage 101 through the first air inlet 102, flow into the room by the first air outlet 103 after passing through the direct current passage 104, and at the same time, The indoor air flows into the exhaust channel 107 through the second air inlet 108, and is discharged outside through the second air outlet 109 after passing through the straight exhaust channel 110, thereby renewing the indoor air. When the cooling and heating load supplied in the direct current channel 104 exceeds the indoor demand, the third control valve 114 and the fourth control valve 115 can be opened. At this time, a part of the outdoor fresh air flows to the first air outlet 103 through the direct current channel 104, and a part of the outdoor fresh air flows through the first air outlet 103. The three air inlets 116 enter the first passage in the heat recovery device 113, while part of the indoor air flows to the second air outlet 109 through the straight discharge passage 110, and part of the indoor air enters the second passage in the heat recovery device 113 through the fourth air inlet 118 , due to the heat transfer between the air flowing through the first channel and the second channel, the heat transfer between the outdoor fresh air in the first channel and the indoor air in the second channel is realized, and the flow direction through the first channel is adjusted The temperature of the outdoor fresh air at the first air outlet 103, the outdoor fresh air passing through the direct flow passage 104 and the outdoor fresh air passing through the first passage are mixed and then flow into the room from the first air outlet 103, and the indoor air passing through the straight discharge passage 110 and the second passage The indoor air is exhausted outside through the second air outlet 109. Since the temperature of the outdoor fresh air flowing into the room can be adjusted, it is beneficial to meet the indoor cooling and heating load while updating the indoor air. By adjusting the first control valve 105, the second The openings of the second control valve 111, the third control valve 114, and the fourth control valve 115 are used to adjust the ratio of the air volume passing through the direct flow passage 104, the straight discharge passage 110, the first passage and the second passage, thereby making the outdoor fresh air flowing into the room The temperature can meet the cooling and heating load required in the room. When adjusting the opening degrees of the first control valve 105, the second control valve 111, the third control valve 114 and the fourth control valve 115 still cannot meet the cooling and heating load required in the room, the first control valve 105 and the second control valve can be The control valve 111 is closed, and the third control valve 114 and the fourth control valve 115 are opened, so that the temperature of the outdoor fresh air flowing into the room can be adjusted to the greatest extent to meet the cooling and heating load required in the room. Therefore, the indoor environment control unit in this embodiment can adjust the indoor temperature while updating the indoor air and ensuring the air quality, reducing the use of traditional cooling or heating equipment such as air conditioners and heaters, and improving the adjustability and flexibility. performance, saving energy. When the first control valve 105 and the second control valve 111 are closed, and the third control valve 114 and the fourth control valve 115 are opened, the cooling and heating loads required in the room can not be met, the first control valve 105 and the When the second control valve 111 is closed and the third control valve 114 and the fourth control valve 115 are opened, the heat pump air conditioner 120 is turned on at the same time, and the temperature of the outdoor fresh air flowing into the room is adjusted through the internal heat exchanger 123 to meet the needs of the room. Cooling and heating loads, since the heat recovery heat exchanger 124 is arranged in the exhaust passage 107 and is arranged closer to the second air outlet 109 than the straight exhaust passage 110 and the fourth air outlet 119 , therefore The air discharged from the fourth air outlet 119 will pass through the heat recovery heat exchanger 124 to exchange heat with the heat recovery heat exchanger 124. Since the temperature of the air discharged from the fourth air outlet 119 will be between the outdoor temperature and the indoor temperature, Therefore, it is more beneficial for the heat recovery heat exchanger 124 to dissipate or absorb heat, thereby improving the cooling and heating efficiency of the heat pump air conditioner 120 and reducing the energy consumption of the indoor environment system. In addition, since the heat recovery heat exchanger 124 is connected in parallel with the external heat exchanger 125, it can effectively prevent the heat recovery heat exchanger 124 from being unable to meet the heat dissipation or heat absorption requirements of the heat pump air conditioner 120 due to the temperature change in the exhaust air passage 107. situation, the reliability of the use of the heat pump air conditioner 120 is improved.
