Abstract
The utility model relates to an air conditioner, which is provided with a heat exchanger of an outdoor machine, wherein the heat exchanger can realize a reverse flow pipeline structure of refrigerating fluid, and consequently, the utility model can realize the purposes that the multiplex diffluence of a cooling medium is even and condensing pressure can be reduced. A pipeline of the heat exchanger of the air conditioner has a simplex supercooling structure which is provided with two air inlet pipe holes which are arranged side by side and an air outlet pipe hole. When the cooling medium flows into the heat exchanger, the cooling medium firstly and respectively flows across two branch air inlet pipelines and then is collected to an air outlet pipeline, and finally, the cooling medium is discharged from the heat exchanger through the air outlet pipe hole. The two air inlet pipe holes of the heat exchanger are arranged on a wing pipe which is arranged on the upper section of the inner side of the heat exchanger side by side, and the air outlet pipe hole is arranged on the lowest end of a windward side formed by air which is exhausted by a blower. The lengths of the two branch air inlet pipelines are the same, and the proportion value of the length of any one branch air inlet pipeline and the length of the air outlet pipeline is (1-1.1): 1.
Description
Technical field
The utility model relates to the improvement design at the heat converter structure of air-conditioner outdoor unit.
Background technology
Air-conditioner outdoor unit generally adopts the heat-pump-type circulatory system at present, carries out the switching of refrigerating operaton and warming operation by refrigerant line.
The off-premises station of existing air-conditioner, its blower fan normally is arranged on heat exchanger the place ahead, heat exchange air from the side or front face side flow through finned tube type heat exchanger body.In the refrigerating operaton process, the cold-producing medium inflow heat exchanger initial stage is that gaseous state, temperature height and flow velocity are very fast; Carry out the heat exchange of a period of time in the heat exchanger pipeline after, cold-producing medium changes gas-liquid mixed or liquid state into by gaseous state, and flow velocity is slack-off.
With above-mentioned cold-producing medium form with change in flow is corresponding is, the off-premises station heat exchanger air inlet pipe group of existing air-conditioner generally adopts 4-6 road air inlet, 1 road to give vent to anger, and has promptly adopted single channel and has crossed the design of cold junction structure.Because the flow velocity of cold-producing medium in the heat exchanger pipeline first quick and back slow, and the pipe group structure of existing outdoor heat converter is complicated, the shunting of refrigerant multichannel is difficult for dividing equally during refrigeration, and refrigerant flow rate is slower, cause the outdoor heat converter heat exchange inhomogeneous, condensing pressure is higher, and outdoor heat exchange effect is not good.
The utility model content
Air-conditioner described in the utility model, its purpose are to address the above problem with deficiency and design the off-premises station heat exchanger that realization cold-producing medium reverse flow pipeline structure is arranged, thereby realization refrigerant multichannel is shunted the purpose of all even reduction condensing pressure.
Described air-conditioner, its off-premises station hold and are provided with compressor, four-way switching valve, outdoor heat converter and as the electric expansion valve of expansion mechanism, and form heat exchange circulation system by refrigeration pipe.
Be provided with blower fan in outdoor heat converter the place ahead, run through finned tube by heat exchanger by the air of sending from front to back, alternately with pipeline in the cold-producing medium heat-shift that flows.
Heat exchanger described in the utility model, its circuit design is for having 2 tunnel air inlet mouths of pipe side by side, and 1 road single channel of giving vent to anger the mouth of pipe is crossed the cold junction structure.
After refrigerant flowed into described heat exchanger, two the branch's air inlet pipelines of flowing through respectively earlier gathered then simultaneously to one road outlet pipe, and finally discharged heat exchanger through 1 road mouth of pipe of giving vent to anger.
Described heat exchanger, its 2 tunnel air inlet mouth of pipe set within it on the epimere finned tube of side abreast, and 1 road mouth of pipe of giving vent to anger is arranged on blower fan and sends the formed windward side of air bottom.
Therefore, the bulk flow of refrigerant in described heat exchanger pipeline just forms the reverse flow pipeline structure of refrigerant to send the flow direction of air reciprocal with the off-premises station blower fan.
Refrigerant is after 2 tunnel air inlet mouths of pipe enter, and one road refrigerant is circulated to the road outlet pipe that gathers downwards after travelling up to the finned tube upper end again; And another road refrigerant travels up to finned tube and upwards is circulated to the road outlet pipe that gathers again after second, and the refrigerant stream after gathering is by finally being discharged by the mouth of pipe of giving vent to anger bottom behind one road outlet pipe.
Therefore, to enter into the flow direction of two-way branch air inlet pipeline also be reciprocal to refrigerant.
Described heat exchanger, the length of two branch's air inlet pipeline is identical.
The length ratio value of described arbitrary branch air inlet pipeline and outlet pipe is (1～1.1): 1.
As the air-conditioner of above-mentioned structure when the refrigeration, refrigerant be divided into 2 the tunnel enter the off-premises station heat exchanger after, coolant distribution is comparatively even, this moment, refrigerant was that gaseous state and flow velocity are very fast; After refrigerant flowed into one road outlet pipe, refrigerant was slower based on liquid state and flow velocity.
As mentioned above, have the air-conditioner of above-mentioned off-premises station heat exchanger, the refrigerant distributed uniform, the condensing pressure in the pipeline is lower, thereby the complete machine energy consumption is less, and EER is higher.
Description of drawings
Fig. 1 is the structural representation of described air-conditioner outdoor unit heat exchanger.
As shown in Figure 1, the air inlet mouth of pipe 1,2, the mouth of pipe 3 of giving vent to anger, refrigerant converge place 4.
The specific embodiment
Embodiment 1, and as shown in Figure 1, described air-conditioner outdoor unit heat exchanger the place ahead is provided with blower fan, and described heat exchanger is provided with 1,2,1 mouths of pipe 3 of giving vent to anger of the air inlet mouth of pipe side by side.
Described 2 tunnel air inlet mouths of pipe 1,2 all are provided with on the epimere finned tube of inboard of heat exchanger, and 1 road mouth of pipe 3 of giving vent to anger is arranged on heat exchanger front finned tube bottom.
Refrigerant is after 2 tunnel air inlet mouths of pipe 1,2 enter, and the flow direction of refrigerant in two-way branch air inlet pipeline is reciprocal.
The length ratio of two branch's air inlet pipelines of described heat exchanger is 1: 1.
The length ratio of described arbitrary branch air inlet pipeline and outlet pipe is 1.1: 1.
