mixing in the outdoor of first passage, room air through in line passage and the room air through second channel are by outside the second air outlet discharge chamber, because the temperature flowing into the indoor new wind in outdoor can be adjusted, therefore while upgrading room air, be beneficial to the cooling and heating load of satisfied indoor needs, by adjusting the first control valve, second control valve, the aperture of the 3rd control valve and the 4th control valve adjusts through direct current channel, in line passage, the air quantity ratio of first passage and second channel, the temperature of the new wind in the outdoor of inflow indoor is enable to meet the cooling and heating load of indoor needs thus.When the aperture of adjustment first control valve, the second control valve, the 3rd control valve and the 4th control valve still can not meet the cooling and heating load of indoor needs, first control valve and the second control valve can be closed, and the 3rd control valve and the 4th control valve are opened, the temperature of the new wind in the outdoor of inflow indoor is made to access maximum adjustment thus, with the cooling and heating load of satisfied indoor needs.Indoor environmental condition control unit provided by the invention can play the effect of adjustment indoor temperature while upgrading room air, ensureing air quality thus, decrease the use of the conventional refrigeration such as air-conditioning, heating installation or heating equipment, improve modulability and flexibility, save the energy.When the first control valve and the second control valve are closed, and when still can not meet the cooling and heating load of indoor needs after the 3rd control valve and the 4th control valve being opened, can to close at the first control valve and the second control valve and under the 3rd control valve and the 4th control valve state of opening, open heat pump air conditioner simultaneously, the temperature flowing into the indoor new wind in outdoor is adjusted by internal exchanger, with the cooling and heating load of satisfied indoor needs, because heat recovering heat exchanger is arranged in described air exhaust passage, and arrange closer to described second air outlet relative to described in line passage and described 4th air outlet, the air of therefore being discharged by the 4th air outlet can carry out heat exchange through heat recovering heat exchanger and heat recovering heat exchanger, because the temperature of the air of the 4th air outlet discharge can between outdoor temperature and indoor temperature, therefore heat recovering heat exchanger heat radiation or heat absorption is more conducive to, and then the refrigeration of heat pump air conditioner can be improved, heating efficiency, reduce indoor environment system energy consumption.In addition, because heat recovering heat exchanger is in parallel with external heat exchanger, therefore, the change due to temperature in air exhaust passage can effectively be avoided, heat recovering heat exchanger can not meet the situation of heat pump air conditioner heat radiation or endothermic heat demand, improves the reliability that heat pump air conditioner uses.

air outlet 109 by line passage 110 simultaneously, part room air is entered the second channel in heat reclamation device 113 by the 4th air inlet 118, because the air flowing through first passage and second channel can carry out heat transmission, thus make to realize heat transmission between the room air in the new wind in the outdoor in first passage and second channel, and then have adjusted the temperature flowing to the new wind in outdoor of the first air outlet 103 through first passage, indoor are flowed into by the first air outlet 103 through the new wind in the outdoor of direct current channel 104 with after the new wind mixing in the outdoor of first passage, room air through in line passage 110 and the room air through second channel are by outside the second air outlet 109 discharge chamber, because the temperature flowing into the indoor new wind in outdoor can be adjusted, therefore while upgrading room air, be beneficial to the cooling and heating load of satisfied indoor needs, by adjusting the first control valve 105, second control valve 111, the aperture of the 3rd control valve 114 and the 4th control valve 115 adjusts through direct current channel 104, in line passage 110, the air quantity ratio of first passage and second channel, the temperature of the new wind in the outdoor of inflow indoor is enable to meet the cooling and heating load of indoor needs thus.When the aperture of adjustment first control valve 105, second control valve 111, the 3rd control valve 114 and the 4th control valve 115 still can not meet the cooling and heating load of indoor needs, first control valve 105 and the second control valve 111 can be closed, and the 3rd control valve 114 and the 4th control valve 115 are opened, the temperature of the new wind in the outdoor of inflow indoor is made to access maximum adjustment thus, with the cooling and heating load of satisfied indoor needs.Indoor environmental condition control unit thus in the present embodiment can play the effect of adjustment indoor temperature while upgrading room air, ensureing air quality, decrease the use of the conventional refrigeration such as air-conditioning, heating installation or heating equipment, improve modulability and flexibility, save the energy.When the first control valve 105 and the second control valve 111 are closed, and when still can not meet the cooling and heating load of indoor needs after the 3rd control valve 114 and the 4th control valve 115 being opened, can to close at the first control valve 105 and the second control valve 111 and under the 3rd control valve 114 and the 4th control valve 115 state of opening, open heat pump air conditioner 120 simultaneously, the temperature flowing into the indoor new wind in outdoor is adjusted by internal exchanger 123, with the cooling and heating load of satisfied indoor needs, because heat recovering heat exchanger 124 is arranged in described air exhaust passage 107, and arrange closer to described second air outlet 109 relative to described in line passage 110 and described 4th air outlet 119, the air of therefore being discharged by the 4th air outlet 119 can carry out heat exchange through heat recovering heat exchanger 124 and heat recovering heat exchanger 124, because the temperature of the air of the 4th air outlet 119 discharge can between outdoor temperature and indoor temperature, therefore be more conducive to heat recovering heat exchanger 124 dispel the heat or absorb heat, and then the refrigeration of heat pump air conditioner 120 can be improved, heating efficiency, reduce indoor environment system energy consumption.In addition, because heat recovering heat exchanger 124 is in parallel with external heat exchanger 125, therefore, effectively can avoid the change due to temperature in air exhaust passage 107, heat recovering heat exchanger 124 can not meet heat pump air conditioner 120 and dispel the heat or the situation of endothermic heat demand, improves the reliability that heat pump air conditioner 120 uses.
Last it is noted that above each embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
