This utility model embodiment provides a kind of building, including the indoor environmental condition control unit described in this utility model any embodiment, described first air inlet 102 connects with outdoor with the second air outlet 109, and described first air outlet 103 connects with indoor with the second air inlet 108.
In the present embodiment, when indoor air needs to be updated and the cooling and heating load of indoor needs can be met by the new wind in outdoor, the 3rd control valve 114 and the 4th control valve 115 can be closed and open the first control valve 105 and the second control valve 111, open the first blower fan 106 and the second blower fan 112 simultaneously, now, outdoor new wind can enter air intake passage 101 by the first air inlet 102, indoor are flowed into by the first air outlet 103 after direct current channel 104, simultaneously, room air is then flowed into air exhaust passage 107 by the second air inlet 108, after described in line passage 110 by the second air outlet 109 discharge chamber outside, room air is thus made to be updated.nullWhen in direct current channel 104, the cooling and heating load of supply exceedes indoor demand，The 3rd control valve 114 and the 4th control valve 115 can be opened，Now the outdoor new wind of a part flows to the first air outlet 103 by direct current channel 104，The outdoor new wind of a part is entered the first passage in heat reclamation device 113 by the 3rd air inlet 116，The most a part of room air flows to the second air outlet 109 by line passage 110，A part of room air is entered the second channel in heat reclamation device 113 by the 4th air inlet 118，Heat transmission can be carried out owing to flowing through the air of first passage and second channel，So that the heat that realizes between the outdoor new wind in first passage and the room air in second channel transmits，And then have adjusted the temperature of outdoor new wind flowing to the first air outlet 103 through first passage，Through the outdoor new wind of direct current channel 104 and flowed into indoor by the first air outlet 103 after the outdoor new wind mixing of first passage，Outside room air through in line passage 110 and the room air through second channel are by the second air outlet 109 discharge chamber，Can be adjusted owing to flowing into the temperature of indoor outdoor new wind，Therefore while updating room air, it is beneficial to meet the cooling and heating load of indoor needs，Can be 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 outdoor thus making inflow indoor disclosure satisfy that the cooling and heating load of indoor needs.When the aperture adjusting first control valve the 105, second control valve the 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 outdoor thus making inflow indoor accesses farthest adjustment, with the cooling and heating load of satisfied indoor needs.Thus the indoor environmental condition control unit in the present embodiment can play the effect adjusting indoor temperature while updating room air, ensureing air quality, decrease the use of the conventional refrigeration such as air-conditioning, heating installation or heating equipment, improve modulability and motility, save the energy.nullWhen 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 be in the first control valve 105 with the second control valve 111 is closed and the 3rd control valve 114 and the 4th control valve 115 are opened，Open heat pump air conditioner 120 simultaneously，The temperature flowing into indoor outdoor new wind is adjusted by internal exchanger 123，Cooling and heating load with satisfied indoor needs，Owing to 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，Therefore the air discharged by the 4th air outlet 119 can carry out heat exchange through heat recovering heat exchanger 124 and heat recovering heat exchanger 124，Owing to the temperature of the air of the 4th air outlet 119 discharge can be between outdoor temperature and indoor temperature，Therefore it is 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.Additionally, owing to heat recovering heat exchanger 124 is in parallel with external heat exchanger 125, therefore, can be prevented effectively from due to the change of 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.
