In addition, the outlet of compressor 15 is connected to the inlet of condenser 17 by a discharging hose 22 (pipeline).The outlet of condenser 17 is connected to the inlet of receiving dryer 18 by a pipeline 23 (pipeline) that forms one with condenser 17.Receiving dryer 18 is connected to the inlet 19a of expansion valve by receiving dryer outlet hose 24.The outlet 20a that is connected in the evaporator 20 of expansion valve 19 is connected to the inlet of compressor 15 by a suction hose 25.Therefore, constituted a refrigerating cycle by making the interconnective pipeline of these members.
As shown in Figure 3, one discharging hose 22 forms in such a way, promptly, at the two ends with flexible molded flexible pipe 26, suitable bend pipe 27,28 with connector portions 27a, 28a is connected to driving engine 15 1 sides and condenser 17 1 sides respectively, and flexible pipe 22 extends to the inlet of the condenser 17 that is installed on the car body from the outlet of the compressor 15 that is installed on driving engine 10.In Fig. 3, label 29 expressions one protector.
As shown in Figure 4, one receiving dryer outlet hose 24 forms in such a way, promptly, at the two ends with flexible molded flexible pipe 30, suitable bend pipe 31,32 with connector portions 31a, 32a is connected to receiving dryer 18 1 sides and expansion valve 19 1 sides respectively, and flexible pipe 24 extends to the inlet 19a of the expansion valve 19 that is installed on the baffle plate 8 from the outlet of the receiving dryer 18 that is installed on radiator 16.The connector portions 32a of 32b of portion and expansion valve 19 1 sides forms one, and this piece portion can be used to a blank area of close evaporator 20 1 sides of a fixing suction hose 25 as described below.In Fig. 4, label 30a represents a protector, 22 expressions, one high-pressure discharge valve, and 34 expression one inspection doors (site glass), 34A represents that a pair of compresses switch.
As shown in Figure 5, suction hose 25 constitutes in such a way, that is, at the two ends with flexible molded flexible pipe 35, the suitable bend pipe 36,37 with connector portions 36a, 37a is connected to evaporator 20 1 sides and compressor 15 1 sides.Pipeline 36 passes through the top of pillar 14 from the outlet slot approximate horizontal ground of the evaporator 20 that the inlet 19a that is parallel to the expansion valve 19 that is installed on the baffle plate 8 is provided with, and is suitable for being connected in pillar 14 by a clip 38.Suction hose 25 is suitable for forming from the inlet of the compressor 15 that is installed on driving engine 10 and extends further.In Fig. 5, label 39 expressions one low pressure blowoff valve, label 40 expressions one protector.
Next the pre-assy step of each device that is positioned at driving engine one side will be described in conjunction with Fig. 6.For clarity sake, engine body is not shown in Fig. 6.As shown in Figure 6, by bolt 42 and sleeve pipe 41 condenser 17 is installed in the front portion that mat top hose (not shown) and bottom hose (not shown) are connected in the radiator 16 of driving engine 10.At the sidepiece of radiator 16, by bolt 43 receiving dryer 18 is installed, the pipeline 23 of condenser 17 is connected in the inlet of receiving dryer 18 by bolt 44.The connector portions 27a of discharging hose 22 is connected in the outlet of the compressor 15 that is installed on the driving engine 10, and connector portions 28a is connected in the inlet of condenser 17.In addition, will be positioned at the outlet that the connector portions 31a that receives outlet hose 24 1 ends is connected in receiving dryer 18 by bolt 47.
Therefore, compressor 15, radiator 16, condenser 17, receiving dryer 18, discharging hose 22 and receiving dryer outlet hose 24 can be assembled in as the driving engine 10 of the engine installation 12 that is connected in transverse axis 11 and obtain a sub-component.Subsequently, the comfort feature when considering conveyance or being installed on car body, suggestion is with suitable anchor clamps etc. and driving engine 10 (engine installation 12) come together supporting radiator 16 and receiving dryer outlet hose 24.
The number of assembling steps of each vehicle body side part is described below in conjunction with Fig. 7.As shown in Figure 7, in the car chamber of baffle plate 87 one sides, the fridge equipment 21 with expansion valve 19 and evaporator 20 has been installed, the inlet 19a of expansion valve 19 and the outlet 20a of evaporator 20 make and stretch into engine room 9.The connector portions 36a of suction hose 25 is plugged in the outlet 20a of evaporator 20, and a clip 38 is installed on the pillar 14 by nut 48 (thru-bolt), so that flexible pipe 25 is fixed to vehicle one side.In Fig. 7, label 49 expressions one master cylinder, 50 expressions, one windshield wiper engine.
To mainly the installation steps that driving engine 10 (engine installation 12) are installed on car body be described below in conjunction with Fig. 7.For clarity sake, engine body is not shown in Fig. 7.(normally from bottom to top) puts into engine room 9 with engine installation 12 with suitable method, its position as illustrated in fig. 1 and 2, engine installation 12 is installed on car body by for example engine installation frame, subframe etc., and the radiator 16 that condenser 17 and receiving dryer 18 are together pre-installed then is installed between a lower side member 5 and the upper member 6.
Be preloaded onto the inlet 19a that connector portions 32a on the other end of receiving dryer outlet hose 24 of driving engine 10 1 sides is connected in expansion valve 19, the connector portions 36a of suction hose 25 that inserts the outlet 20a of evaporator 20 fixes by the 32b of piece portion.In addition, be installed in connector portions 37a on the other end of suction hose 25 of car body side is connected in the compressor 15 that is contained in driving engine 10 1 sides in advance by a bolt 52 inlet.Each flexible pipe, pipeline etc. can suitably be clamped in car body and engine installation 12.
Therefore, driving engine 10 (engine installation 12) is installed on car body, compressor 15, condenser 17, receiving dryer 18, expansion valve 19 and evaporator 20 are connected with suction hose by discharging hose 22, pipeline 23, receiving dryer outlet hose 24, thereby form refrigerating cycle.
In addition, because discharging hose 22, receiving dryer outlet hose 24 and suction hose 25 are respectively to make with having flexible flexible pipe 26,30 and 36, thus can carry out connection work easily, and can absorb vibration and noise when starting.
As mentioned above, according to the air conditioner for vehicles of first aspect present invention, condenser and receiving dryer can be pre-installed with radiator and be assigned in driving engine.When by compressor, condenser, receiving dryer with the formed sub-component of pipeline that is used for being connected these parts when being installed on the car body, expansion valve enters the mouth and evaporator outlet is assembled because receiving dryer outlet that can be by will starting pusher side and suction port of compressor are connected to, thereby needn't in a narrow and small engine room, carry out plumbing connection, thereby improved the operability when assembling.
Air conditioner for vehicles according to second aspect present invention, in the time will being installed to sub-component on the car body, as long as the other end of receiving dryer outlet is connected in the outlet of expansion valve, and the other end of suction hose is connected in the inlet of compressor, just can the bundle component groups installs on the vehicle.
According to the air conditioner for vehicles of third aspect present invention because receiving dryer outlet hose and suction hose have flexibility, so they be easy to connect, thereby the operability when having improved assembling.
