Abstract
The utility model relates to a three-way assembled pipe of an air conditioner set with double compressors and a single system, which comprises a main pipe, two branch pipes and a three-way connector on which three pipe interfaces are arranged. The main pipe and the branch pipe are respectively connected with three pipe interfaces which are distributed evenly at 360 DEG. The utility model better solves the problems of uneven oil return of two compressors, high failure rate, big exhaust resistance, big noise, etc.
Description
Technical field
The utility model relates to the car air conditioner assembly, and particularly the threeway composite tube of double compressors single system air-conditioning unit belongs to the improvement of prior art.
Background technique
At present, use two less air condition compressor of discharge capacity to substitute the compressor that discharge capacity is bigger in the part coach air conditioner product, to reach the purpose of under the prerequisite that guarantees the air-conditioning system refrigerating capacity, saving cost.Two kinds of technological schemes are arranged when using two compressors: one is that two compressors connect a cover air-conditioning system separately, is referred to as the air-conditioning unit of double compressors double system, and this technological scheme pipeline complexity is leaked easily, the cost height, and therefore the rate of fault height adopts few; Two is to insert same set of air-conditioning system after the two compressor parallel connections, be referred to as double compressors single system air-conditioning unit, this technological scheme is because not increase of air-conditioning system, just original single compressed machine is changed into two compressors that discharge capacity is less in parallel, therefore avoided above-mentioned first kind of existing shortcoming of technological scheme, but all need to install the threeway composite tube at two compressor inlet ends and exhaust end and realize parallel connection, the distribution of three interface tubes of existing threeway composite tube joint is that person in charge's interface is vertical with two interface tubes, enter two amounts the interface tube and be subjected to the influence of automobile inclined degree bigger from being responsible for fluid shunting that interface flows to like this, fluid resistance is also bigger.Be easy to make the pressure of inspiration(Pi) of two compressors can not be in state of equilibrium, easily cause compressor because oil starvation causes and compress locking, stuck, fault such as clutch burns out because to get back to the amount of refrigerator oil of two compressors during operation of air conditioner inequality; When the compressor air-discharging end merged into one the tunnel by two-way in threeway composite tube fittings body, air resistance was big, easily produced vibration and noise.
The model utility content
The purpose of this utility model is the shortcoming that overcomes prior art, when being provided, a kind of operation of air conditioner can make the pressure of inspiration(Pi) of two compressors be in state of equilibrium, return-air, oil return are even, air resistance is little, avoids because of return-air, the uneven threeway composite tube that causes the double compressors single system air-conditioning unit of compressor fault of oil return.
The purpose of this utility model is realized by following technical proposals.
The utility model comprises a person in charge, two arms and tee union, and tee union is provided with three interface tubes, be responsible for and arm is connected on three interface tubes, three interface tubes be 360 ° uniform.
Above-mentioned arm is bend pipe.
When the utility model uses, it is installed in the inlet end and the exhaust end of two compressors of double compressors single system air-conditioning unit respectively.At inlet end, the person in charge of the present utility model is communicated with the vaporizer of air-conditioning unit, and two arms are communicated with the suction tude of two compressors respectively; At exhaust end, the person in charge of the present utility model is communicated with the condenser of air-conditioning unit, and two arms are communicated with the outlet pipe of two compressors respectively.
The beneficial effects of the utility model are: since three interface tubes of joint be 360 ° uniform, therefore enter two amounts the interface tube and be subjected to the influence of automobile inclined degree less from being responsible for fluid shunting that interface flows to, resistance is little, when the vaporizer return-air is divided into two-way in fittings body like this, even automobile tilts, can not occur causing that owing to level height is inconsistent return-air, oil return inequality cause compressor fault yet; Equally, compressor air-discharging merges into one when being responsible for by two arms in fittings body, and air resistance is little, can effectively reduce vibration and noise.Simultaneously, arm is designed to bend pipe, and through the buffer function of bend pipe, the pressure of inspiration(Pi) of two compressors is in state of equilibrium all the time, and compressor air-discharging is through the buffering of bend pipe, and air-flow is even, can further reduce vibration and noise.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises that one is responsible for 3, two arms 2 and tee union 1, tee union 1 is provided with three interface tubes, as shown in Figure 4, comprising person in charge's interface 11 and two interface tubes 12,13, be responsible for 3 and be connected on person in charge's interface 11, two arms 2 are connected on two interface tubes 12,13, three interface tubes 11,12,13 are uniform in 360 ° of scopes, and the angle of two promptly adjacent interface tubes is 120 °, and two arms 2 are bend pipe.
When the utility model uses, as shown in Figure 5, it is installed in the inlet end and the exhaust end of two compressors 41,42 of double compressors single system air-conditioning unit respectively.At inlet end, the person in charge 3 of the present utility model is communicated with the vaporizer 10 of air-conditioning unit, and two arms 2 are communicated with the suction tude of two compressors 41,42 respectively; At exhaust end, the person in charge 3 of the present utility model is communicated with the condenser 5 of air-conditioning unit, and two arms 2 are communicated with the outlet pipe of two compressors 41,42 respectively.During the work of air-conditioning unit, the exhaust of two compressors that are installed in parallel 41,42 enters a blow-off tee composite tube by two exhaust branch pipes 2, be merged into an exhaust person in charge 3 by tee union 1 and enter condenser, enter vaporizer 10 through cistern 6, exsiccator 7, liquid-sighting glass 8, expansion valve 9, refrigeration agent heat absorption evaporation back cooled via return air is responsible for 1 and is entered return-air threeway composite tube, be divided into two-way by tee union 1 and enter two air intake branches 2 and enter compressor 41,42 respectively, finish the circulation of refrigeration agent.
Problems such as the utility model utilization uniform 11,12,13 and two crooked arms 2 of three interface tubes in 360 ° of scopes have solved two compressor oil return inequalities, rate of fault height well, and exhaust resistance is big, and noise is big.
