In the case of a ventilation unit 4 , ,, in the case of outdoor air, when the room is heated to heat the room, during the ventilation, the person feels unpleasant. The invention proposes to cool or lose the room heated in the room through the outer air and the outdoor air in the room, and the air in the room can be ventilated by opening the window or the door. When the room is ventilated, because the cooling heat will be added to the room air, or the heat of the gas will be lost to the outdoors, after the ventilation, there will be more energy suddenly introducing the outdoor air, it is difficult to eliminate, thus solving these problems The pre-heat exchanger 440 is installed in the technology 410, and the error of the pre-class road 4 11 a and the second flow channel 4 11 b is indirect heat exchange. In the case of heating the room, heat is transferred from the room air to the supply during ventilation. In the outdoor air to the room, Fig. 6 illustrates an embodiment of the preheat exchanger, and the preheat exchanger 44 will be described in conjunction with Figs. Referring to FIGS. 5A to 6 , the preheat exchanger 44 〇 includes a plurality of third flow passages 441 for room air flow and a plurality of fourth flow passages for outdoor air flow 4 4 2 'multiple The three flow passages 4 4 1 are spaced apart from each other by a regular interval, and each of the fourth flow passages 442 is disposed between and in contact with the adjacent third flow passage 441, so that the preheat exchanger 440 is The three flow paths 441 and the fourth flow path 442 - one layer overlap each other. Each of the layers of the preheat exchanger 440 is a flat plate 443, and a plurality of flat plates 443 are spaced apart by a predetermined interval in the up and down direction to form a third flow path 441 and a fourth flow path 442 in which the layers overlap each other. The preheat exchanger 44 is inserted into the outer casing 41 0 or, more particularly, the base 411. For this purpose, the inner surface of the base 4 11 has vertical ridges 411 e for use.

1284187 Case No. 93102289 V. Description of Invention (13) To support the corners of the preheat exchanger 440, when the preheat exchanger 440 is inserted into the base 411, the plurality of ridges 411 e slidably guide the preheat exchanger 440 And after the preheat exchanger 404 is completely inserted into the base 4 11 , the corner of the preheat exchanger 440 can be supported to prevent the preheat exchanger 44 移动 from moving in the lateral direction because the outer cover 41 3 is disposed on the base Above the open upper half of the 4-11, the preheat exchanger 404 is not movable even in the vertical direction, so the preheat exchanger 44 accommodated between the ridges 4丨丨e is completely fixed. 442. In this case, in the case of heating the room, after flowing through the third flow-through preheating parent exchanger 4404, the room air flowing along the first flow path 4 11 a flows to the pre-heat exchanger. The third flow path 441 of 44 ,, the outdoor air flowing along the second flow path 41 lb flows to the heat exchanger of the pre-heat exchanger "the fourth air flow path 441 is transmitted through the flat plate 443 to the fourth In the case of cooling the room, the outdoor &amp; gas of the flow path 4 4 2 flows through the fourth flow path 4 &amp; 2, and the heat of the air passes through the flat plate 443 to the room flowing through the third flow path 441. ' ^This, once the preheater 440 is set, in the heating room situation: enough to recover heat from the room air, in the case of cooling the room i can recover heat from the outdoor air, avoid energy waste when ventilation, Shorten the cooling or heating time of the room. There is a flow guide 444 between the adjacent plates 443 to guide the room to the direction of the flow of the crying milk and the outdoor air, thus improving the preheating exchange 440 i heat exchange capacity, the flow guide 444 is wavy, making the wave 7 good board Top plate 444 and lower plate 443 # H contacts the top and bottom alternately to the flow guide plate, each floor is provided with a flat plate. Once the pre-heat exchanger 440 is provided wavy flow guide plate 444, will increase

1284187 _ Case No. 93102289 Revised on the fifth day of the month, invention description (14) &quot;^ The contact area between the room air and the outdoor air, and the heat-replacement ability of the preheat exchanger 44 () can be recovered from the room air or outdoor air Thermal energy. The flow guides of the third flow path 4 41 and the flow guide openings of the fourth flow path 4 4 2 are disposed substantially perpendicular to each other, and then the room air flows perpendicularly to the outdoor air y, indirectly in the preheat exchanger 440 Perform heat exchange. Only the preheat exchanger 440 can be used to make the room air or the outdoor air flow through the preheat exchanger 440 from the multi-layer corrUgated paper with the addition of the loess component. The smell of air and outdoor air, and the flow noise of the room air and households. On the other hand, referring to Figures 5B and 6, the preheat exchanger 44 is provided with a sealing member 445 which may be formed of rubber or sponge surrounding the corner of the preheat exchanger 44, as the preheat exchanger 44 〇 Installed in the outer casing 4丄〇, and the sealing member 445 is provided, the air leakage between the room air and the outdoor air between the inner wall of the outer casing 41 and the corner of the exchanger 44 0 can be avoided.

In addition, the sealing member 445 can avoid the vibration of the preheater 440 caused by the rapid flow of air. The blade H 珲 fan unit 400 can further be provided with a filter 45 0. As shown in FIG. 5B and FIG. 7 , the filter 45 0 is disposed in the second flow path 4Ub of the ventilating unit 40 0 for removing the supply to the room. The inclusions in the outdoor air, for example, the filter cry 450 can be placed in close proximity to one side of the preheat exchanger 44. With the structure of the screen mesh ^, it is possible to completely remove the inclusions in the outdoor air and prevent the entry of the pipe, the pipe 430, the filter 45 0 and the preheating exchange of the corrugated paper containing the loess component, and finally, the ventilation unit 4 〇〇 able to supply clean outdoor air

Into the room. In the circulation between the chambers, if there is heat in the room under the front panel, when the room inside the inclusions is hot, and then the fan is required to be ventilated, the wind is outside and the ventilation is in the picture, sinking, and the outside air is clean. The operation instructions of the air conditioner with the ventilator installed separately are as follows. When the compressor in the internal machine is operated, the refrigerant is passed through the refrigerant pipe 1 5 〇 in the indoor hot parent converter 300 and the heat exchanger (not shown) in the outdoor unit. In the case of heating the room, the heat exchanger 3 〇〇 From the room air, in the case of cooling the room, the heat exchanger 3 〇〇 releases the heat to the room. The fan 20 0 cooperates with the above process, and the room air is located in the lower half of the box i 〇〇 The air inlet enters the casing 1,, in which case the room air passes through the first filter 127 and the second filter 131, and the odor particles are completely removed from the room air. The exchanger 30 is subjected to heat exchange to be cooled or supplied to the room by the air outlet 1 2 1 . Two parties, if the above process is carried out for a long time, the air is polluted by the wind, in this case, the compressor stops running, the wind _, the group 40 0 motor 421 starts to hold you a V soil belongs to 2〇0 and ^ Qu is enough to start the operation. When the motor 421 is operated, the second==the second fan 425 is operated to discharge the room air to the air to the room, and the room is empty and the room is empty; =:==: Monthly ventilation process' So no further need: two?匕; 1, shown in the 7th ventilation period, the preheater 440 from the room 'heating the room, the combination, the household, s + + ^ between the work heat transfer energy to the Toda", when ventilating, The room air supplied to the phase needs to be transferred to the room, and the wind is supplied to the room by the ventilation unit 40 0
