At this moment, though do not show among the figure, can be with above-mentioned evaporative freezing circulator at the above-mentioned housing 100 inner compressor of freeze cycle devices, condensing heat exchanger, the expansion valves etc. installed, but had better be contained in addition separately in the off-premises station to good in order to reduce the noise that sends from compressor etc.
In the lower inside of above-mentioned housing 100 the inner loop inlet hole 151 of forcing to suck room air is arranged, and above-mentioned inner loop inlet hole is communicated with supply air line 120 on the back location that is positioned at heat exchanger 110.Like this, when air supply fan 125 started work, room air then flowed into supply air line by above-mentioned inner loop inlet hole 151, and continues to flow through evaporation heat-exchanger 1, be discharged to again by air feed tap 123 indoor, shown in Fig. 2 a-2.
At this moment, on the above-mentioned supply air line 120, first control valve 160 that can selectively open and close inner loop inlet hole 151 is housed.Above-mentioned first control valve 160 should be not only can open and close the inner loop inlet hole, and can selectively block the supply air line that passes heat exchanger 110 for well.This is in order freely to select the outdoor air by above-mentioned heat exchanger 110, room air through evaporating heat exchanger 1 flow into indoor heat exchanger form and flows into by above-mentioned inner loop inlet hole 151 flows into indoor inner loop form through evaporating heat exchanger again.
For this reason, above-mentioned first control valve 160 is to be made of the plate that the hinge 161 on the supply air line 120 between heat exchanger 110 and the inner loop inlet hole 151 can rotate up and down for the center.Like this, when first control valve 160 during at the horizontal cross state, inner loop inlet hole 151 will be closed, and the supply air line of heat exchanger back is then opened simultaneously; When above-mentioned first control valve 160 was in plumbness, the inner loop inlet hole can be opened, and the supply air line of heat exchanger back then is closed simultaneously.
In the indoor of above-mentioned housing 100, its underpart is provided with the inlet hole 141 of forcing to suck room air; Above-mentioned circulation inlet hole is and places the gas exhaust piping 130 of heat exchanger 110 back to be connected along the flow direction of discharging air.Like this, when starting exhaust fan 135, room air flow into gas exhaust piping by above-mentioned single cycle inlet hole 141, and is discharged to outdoor through tap 133.
In this case, for opening and closing the monodromy aspiration hand-hole on the above-mentioned gas exhaust piping 130 selectively, second control valve 170 is housed, above-mentioned second control valve 170 can selectively block the gas exhaust piping that passes heat exchanger.This is that room air for the above-mentioned heat exchanger 110 of can freely selecting to flow through is discharged to the room air that outdoor heat exchange scavenging way and the above-mentioned monodromy aspiration hand-hole 141 of flowing through flow into and is discharged to outdoor monodromy gas mode.
For this reason, above-mentioned second control valve 170 also is the same with first control valve 160, is the center with the hinge 171 on the gas exhaust piping between heat exchanger 110 and the monodromy aspiration hand-hole 141, and the flat board that can rotate up and down constitutes.Like this, when second control valve 170 was in the horizontal direction transverse state, monodromy aspiration hand-hole 141 was closed, and the gas exhaust piping of heat exchanger back is opened simultaneously.When second control valve 170 was in plumbness, the inlet hole of taking a breath merely can be opened, and the gas exhaust piping of heat exchanger back is closed simultaneously.
The air-conditioner course of work of tool ventilatory of the present invention is described as follows:
At first, shown in Fig. 2 a-1,2a-2, first control valve 160 is closed inner loop inlet hole 151, the time second control valve 170 with monodromy aspiration hand-hole 141 closing state, this is the state with heat exchanger form running.
At first, along with exhaust fan 135 starts running, room air flows into gas exhaust piping 130 by exhaust inlet hole 131.Flow into the room air heat exchanger 110 of flowing through like this and be discharged to outdoor going through exhaust taps 133.
Meanwhile, along with air supply fan 125 starts running, outdoor air flows in the supply air line 120 by air feed inlet hole 121, and continues through over-heat-exchanger 110.At this moment, above-mentioned outdoor air, when flowing through heat exchanger 110 and indoor cold air carry out exchange heat, it is cooled to a certain degree.Then, be cooled to outdoor air to a certain degree, passed through evaporating heat exchanger 1 again, be cooled to fully conform to indoor environment and flow into indoor by air feed tap 123.
In above-mentioned heat exchanger mode, contaminated room air is carrying out the outdoor air that above-mentioned heat exchanger of scavenging period while is imported, and carries out an exchange heat earlier and flows into afterwards indoor again.
State shown in Fig. 2 b-1 is, first control valve 160 is when closing inner loop inlet hole 151,170 of second control valves are opened simple inlet hole 141, block the gas exhaust piping of heat exchanger back simultaneously, and this is the operating condition of simple endless form.
At first, exhaust fan 135 starts running, and room air flows into gas exhaust piping 130 through simple ventilation inlet hole 141, and the tap 133 that continues to flow through is discharged into outdoor.At this moment room air, and without heat exchanger 110.
Meanwhile, start air supply fan 125, outdoor air then flows into supply air line 120 through air feed inlet hole 121, and the heat exchanger 110 that continues to flow through, flow through evaporating heat exchanger 1 again, at this moment, outdoor air does not carry out exchange heat in heat exchanger, but in evaporating heat exchanger, under the heat-absorbing action of refrigerant, be cooled, indoor by 123 inflows of air feed tap again, shown in Fig. 2 b-2.
Like this, in above-mentioned simple scavenging way, contaminated room air just merely is discharged into outdoor, and the outdoor air with input does not carry out exchange heat.Above-mentioned outdoor air just carries out exchange heat in evaporating heat exchanger.This simple scavenging way is when indoor temperature is higher than outdoor temperature when initial running, and is very suitable when needs prevent that the outdoor air of importing from being heated by room air.
State shown in Fig. 2 c-1 is, first control valve is opened inner loop inlet hole 151, to close the supply air line of heat exchanger 11 back simultaneously, second control valve 170 is then closed simple circulation inlet hole 141, exhaust fan 135 is in off working state, and this is a kind of operating condition of inner loop heat exchange mode.
Along with the air supply fan entry into service, room air flows in the supply air line 120 by inlet hole 151, and the evaporating heat exchanger 1 that continues to flow through, and is cooled under the heat-absorbing action of refrigerant simultaneously, the room air that is cooled then flows back to indoor again by input gas steam vent 123, shown in Fig. 2 c-2.At this moment, though air supply fan 125 in running because the supply air line of heat exchanger 110 back closes, so outdoor air can not flow in the supply air line, and exhaust fan does not turn round, room air can not discharged outdoor yet.
Like this, in above-mentioned inner loop heat exchange mode, gas exchange action does not take place in room air.And just follow general air-conditioner such, the ringing of simple room air only takes place.
