This is in order to start at evaporation heat-exchanger (1) before the running, when indoor temperature is higher than outdoor temperature, and the temperature that allows the room air of discharging remove to raise the input room air.
Have above-mentioned pipeline structure the air-conditioner of tool ventilatory, its structure and effect are described in detail as follows:
Shown in Fig. 2 a-1, the air-conditioner of first embodiment of the invention tool ventilatory has box-type shell (100), and portion is provided with supply air line (120) that constitutes the air feed path and the gas exhaust piping (130) that forms exhaust channel within it, and both intersect to be installed with mutually.At above-mentioned supply air line and gas exhaust piping infall heat exchanger (110) is housed.
The air feed inlet hole (121) that communicates with supply air line is equipped with in the upper end, outside of above-mentioned housing (100), housing (100) inside lower end then is equipped with the air feed tap (123) that communicates with supply air line, is equipped with in air feed tap one example of above-mentioned supply air line (120) outdoor air is forced air supply fan in the suction chamber.
In addition, the discharge aspiration hand-hole (131) that communicates with gas exhaust piping is equipped with in the upper end, indoor of above-mentioned housing (100), and in the lower end, the outside of housing (100), the exhaust tap (133) that communicates with gas exhaust piping then is housed, then is equipped with in exhaust tap one side of gas exhaust piping (130) and forces to suck room air and be discharged to the outdoor exhaust fan that goes (135).
Above-mentioned supply air line (120) and gas exhaust piping (130) are become the enclosure interior space segmentation up and down two-part dividing plate separately by one, so that it does not disturb mutually.
Above-mentioned heat exchanger (110) is a hexahedron, and its two side corner angle are vis-a-vis supporting with the upper and lower of housing (100) respectively, and air feed path and exhaust channel then cross one another, and connects two sides vis-a-vis separately.
Be equiped with the evaporation heat-exchanger (1) that constitutes the freeze cycle device near the inner air supply fan of above-mentioned supply air line (120), and above-mentioned evaporation heat-exchanger (1) should be contained in the rear along the air supply fan (125) of air feed air flow.
At this moment, though do not show among the figure, can be with above-mentioned evaporative freezing circulator at the inner compressor of freeze cycle device, condensing heat exchanger, the expansion valve etc. installed of above-mentioned housing (100), 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.
The inner loop inlet hole (151) of forcing to suck room air is arranged in the interior routine bottom of above-mentioned housing (100), 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) when being in plumbness, the inner loop inlet hole can be opened, and the supply air line of heat exchanger back then is closed simultaneously.
Indoor in above-mentioned housing (100), its underpart are 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) that is positioned 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) when being 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 tap (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, during the heat exchanger of flowing through (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), second control valve (170) is then opened simple inlet hole (141), blocks 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 air feed tap (123) inflow 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 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, under the heat-absorbing action of refrigerant, be cooled 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 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.
Shown in Fig. 3 a the structure and the heat exchanger mode schematic diagram of the air-conditioner of the present invention's second example tool ventilatory; Fig. 3 b is the air-conditioner inner loop mode schematic diagram of expression the present invention second example tool ventilatory.
