[embodiment]
Below, one embodiment of the invention are illustrated among Fig. 1, by this embodiment the situation of air-cooling system are elaborated.At this, Fig. 1 is the skeleton diagram of the indoor set of interior environment system.In Fig. 1, the 1st, car body, the 2nd, the indoor set of interior environment system.In addition, do not have the off-premises station of expression among the figure, be configured in the inboard of indoor set 2.
This indoor set, in order to change wind in the car, the integrated ventilation of the supply and exhaust supply ventilating fan 10 that fan blade is installed at the two ends of diaxon motor is equipped with in inside, and in this figure, the fan blade on right side is the exhaust supply ventilating fan, and the fan blade in left side is to the gas supply ventilating fan.Fresh air sucks from the gas port 30 of giving that is located at the car end, by giving gas passage 20, from the ventilation supply ventilating fan 10 of giving the gas side, to the 1st i.e. the 1st indoor heat converter air-supply of evaporator 11.
On the other hand, by chamber wind supply ventilating fan 13, from the circulating air QR of vehicle floor face suction, promptly return (return) air, returning air flue 22 midway, from aspiration ventilation road 21 only after the air quantity of exhaust gas extraction air QE, in evaporator 11 and the fresh air QF that is cooled mix.At this, the air quantity of fresh air QF and air-out QE is identical.By being that the 2nd indoor heat converter is cooled at the 2nd evaporator 12, utilize indoor blower 13 in the guest room, to blow again from air-supply passage 23, adjusting air QS that sends into and the air quantity of circulating air QR equate.In addition,, outside car, discharge with supply ventilating fan 10 air in the car that exhaust passage 21 sucks by ventilation from exhausr port 31.
In the past, the evaporator that has the 1st evaporator that is equivalent to present embodiment and the 2nd evaporator to add ability together, be configured in the position identical (being the situation of a big evaporator) side by side with above-mentioned the 2nd evaporator, the mixing air of the fresh air that is used to cool off the car inner circulating air and outside car, sucks, and because the air quantity of circulating air is doubly most than the air quantity of fresh air, so the temperature of mixing air rises hardly, must increase air circulation for obtaining specified heat exchange amount.
In contrast, with regard to the structure of present embodiment, in the 1st evaporator 11, the heat insulation compression by supply ventilating fan 10 heats up.And fresh air and evaporator than outer temperature Du Genggao carry out interchange of heat, so the heal differential of refrigerant and air strengthens.Like this, the air air quantity reduces, yet heat exchange amount but can reach and dispose evaporator degree much at one in the past.In addition, the ventilation volume of the 2nd evaporator 12, for configuration in the past, because the 1st and the 2nd evaporator 11,12, parallel arranged is so become half of air circulation QR, and concerning the machine construction of present embodiment, become the air quantity identical with air circulation QR, owing to accelerate and the heat transfer efficiency raising by the wind speed of evaporator, heat exchange amount increases.Therefore, in order to obtain specified heat exchange amount, air circulation can reduce.
At fresh air QF that above-mentioned the 1st evaporator 11 is cooled with after circulating air QR mixes, owing to be cooled once more, so the temperature of regulating air QS also can be lower than interior environment system in the past at above-mentioned the 2nd evaporator.That is to say that according to the foregoing description, owing to by above-mentioned the 1st evaporator 11 cool fresh air QF, compare with the interior environment system of the past with same refrigerating capacity, the temperature of regulating air QS can descend.This shows that compare with the interior environment system that has same ability in the past, the adjusting amount of air of supplying with can reduce in car.Regulate amount of air by reducing like this, the air flow circuit sectional area of air-supply passage 23 also can reduce.Like this owing to the air flow circuit sectional area of air-supply passage 23 reduces with compare to some extent in the past, the interior environment system main body can be set at the bottom portion of car body 1, ceiling part from this interior environment system main body to the guest room, extend above-mentioned air-supply passage 23 is set, such structure can guarantee to enlarge the living space as far as possible.That is to say, from the bottom along sidewall, spaced walls or the end walls of car body above-mentioned air-supply passage 23 is set, to the upright structure of ceiling, owing to can reduce and the long-pending sectional area that promptly becomes vertical direction of the passage sections of this air-supply passage 23 with air-flow direction, so can control this air-supply passage 23 as far as possible, the living space in car is outstanding.Therefore, can prevent to reduce the interior living space of car, to guarantee big as far as possible living space owing to the setting of above-mentioned air-supply passage 23.
In addition, because the 1st evaporator 11 is arranged on the discharge side of giving air-flow road of ventilation with supply ventilating fan 10, so, return air flue to gas with the noise process of supply ventilating fan, the phenomenon of propagating in car significantly reduces.
Fig. 2 is the air system figure of presentation graphs 1 embodiment.The 1st refrigerating circulation system 50 is to give the pneumatic transmission blower fan with ventilation with supply ventilating fan 10, the auxiliary refrigerating circulation system that the fresh air QF that will suck outside car cools off, it is made of following several parts, that is: compressor 51, as the 1st distiller 16a of the 1st outdoor heat converter, outdoor blowers 17, dilation 52 and the 1st evaporator 11.
The 2nd refrigerating circulation system 60 is with 1 circulating air that sucks from the guest room, with at the further refrigerating circulation system of cooling of the mixing air of the 1st evaporator 11 cooled airs, it is made of following several parts, that is: compressor the 61, the 2nd distiller 16b, outdoor blowers 17, the mechanism of decompressor the 62, the 2nd evaporator 12, indoor blower 13.Above-mentioned the 2nd distiller is supplied with the outer air of car by outdoor blowers 17 and is dispelled the heat.
At this, the part of circulating air QR is by discharging outside car with the exhaust supply ventilating fan of the exhaust gear of supply ventilating fan 10 as ventilation; Roughly, outside car, suck with the pneumatic transmission blower fan of giving of giving device of air of same ventilation with supply ventilating fan 10 with the air of amount.
