Abstract
The utility model provides an outdoor heat exchanger of an air conditioner, particularly improved technology for reducing energy consumption of the outdoor heat exchanger of an air conditioner, which has a novel heat exchange method. The novel outdoor heat exchanger of an air conditioner comprises a heat exchange passage which is composed of U-shaped pipes. Refrigerant of the air conditioner is collected and condensed after passing through the heat exchange passage. The heat exchange passage is a multi-stage passage. Each stage of the passage is connected by a multi-way joint. Through changing the arrangement and the connection methods of the U-shaped pipes, the method causes the refrigerant to fully utilizes the heat exchange ability of the U-shaped pipes of the heat exchanger when passing through the heat exchanger pipeline, the pressure loss of the refrigerant in the pipes is reduced, the optimum flow division method of the outdoor heat exchanger is obtained, the refrigerating capacity and the heat-production capacity of the refrigeration system are ensured, the energy consumption of the air conditioner is reduced and the energy efficiency ratio is enhanced.
Description
Technical field
The utility model belongs to air-conditioner and makes the field, is specifically related to a kind of improvement technology that reduces the outdoor heat exchanger of air conditioner energy consumption.
Technical background
The outdoor heat exchanger of existing air conditioner cold-warm type adopts the two-stage shunting mode usually when shunting, promptly two advance one and go out or advance more a direct shunting mode that goes out, as shown in Figure 1, this is that two of common 1.5 air-conditioners advance one and go out (2-1 type) hot switching path, this shunting no doubt can be simplified pipeline, make condenser be easy to assembling, but during owing to the air conditioner refrigerating operation, the flow of refrigerant direction is shown in arrow among Fig. 1, the refrigerant gas of HTHP enters outdoor heat exchanger of air conditioner, this moment, the gaseous refrigerant flow velocity was fast, because adopt two inlets, gaseous refrigerant flow area in the coiled pipe of outdoor heat exchanger is not enough, cause refrigerant pressure loss to increase, thereby reduced air conditioner refrigerating efficient, increased energy consumption.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of outdoor heat exchanger of air conditioner that has novel hot switching path arrangement mode is provided, and improves the mode of outdoor heat exchanger of air conditioner heat exchange shunting, cuts down the consumption of energy, and improves air-conditioner efficiency.
The technical scheme of the utility model outdoor heat exchanger of air conditioner is: a kind of outdoor heat exchanger of air conditioner, comprise the hot switching path of forming by U type pipe, and it is characterized in that: described hot switching path is multistage passage, connects by multidirectional connector between every grade of passage.
Described hot switching path is three grades of passages.These three grades of passages comprise and are provided with three or three chopped-off head passages with upper inlet, are provided with the secondary channel that inlet quantity is successively decreased relatively behind some U type pipes of being separated by, and the final stage passage that is provided with an inlet.
Described hot switching path is the level Four passage.This level Four passage comprises sends out the chopped-off head passage that four or more inlet is arranged, and is provided with secondary channel and time secondary channel that inlet quantity is successively decreased relatively behind some U type pipes of being separated by, and the final stage passage that is provided with an inlet.
The beneficial effects of the utility model are that this air-conditioning outdoor heat exchanger is arranged and type of attachment by changing traditional hot switching path, compared with prior art has the following advantages:
1: make full use of the exchange capability of heat of outdoor heat exchanger, reduced the pressure loss of tube refrigerant, guarantee the air-conditioner refrigerating capacity.
2: obtain higher Energy Efficiency Ratio.
3: energy-conserving and environment-protective.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is further described:
Accompanying drawing 1 is the hot switching path of the existing outdoor heat exchanger of air conditioner schematic diagram of arranging;
Accompanying drawing 2 is three grades of hot switching paths of the utility model embodiment 1 schematic diagram of arranging;
Accompanying drawing 3 is the level Four hot switching path of the utility model embodiment 2 schematic diagram of arranging.
The specific embodiment
Embodiment 1:
As shown in Figure 2,1.5 the heat exchanger of an air-conditioning adopts 24 U type pipes 1, use three grades of hot switching paths of the present utility model, when air conditioner refrigerating moves, the flow of refrigerant direction is (3-2-1) shunting mode as shown in Figure 2, the gaseous refrigerant of HTHP enters outdoor heat exchanger of air conditioner, at first enter chopped-off head passage with three inlets, compared with prior art, suitably increased flow area in the outdoor pipe, reduce refrigerant pressure loss, guaranteed the flow velocity of cold-producing medium in pipe of 1.5 air-conditioning HTHPs simultaneously.When the gaseous refrigerant of HTHP is partially condensated as liquid, enter after the two-phase section, Jiang Sanlu merges into two-way, enters the secondary channel with two inlets, guarantees to be in the flow velocity of cold-producing medium in pipe of two-phase section.Last cold-producing medium all is condensed into liquid, enters the liquid monophase field, and merge into one tunnel with two-way this moment, enters the final stage passage with an inlet, guarantees to be in the flow velocity of cold-producing medium in pipe of liquid monophase field.Outdoor heat exchanger in this way makes full use of the exchange capability of heat of outdoor heat exchanger U type pipe 1, reduce the pressure loss of U type pipe 1 inner refrigerant, obtained the best shunting mode of outdoor heat exchanger, guaranteed the refrigerating capacity and the heating capacity of refrigeration system, reduce the air-conditioner energy consumption, improve Energy Efficiency Ratio.
Embodiment 2:
Embodiment 2 compares with embodiment 1, changes three grades of hot switching paths into the level Four hot switching path, is applicable to that mainly the heat exchanger of 2 to 3 air-conditionings adopts, as shown in Figure 3, and for being used for the 4-3-2-1 shunting mode of 2-3 air-conditioning.The gaseous refrigerant of HTHP enters outdoor heat exchanger of air conditioner, at first enter chopped-off head passage with four inlets, suitably increased flow area in the outdoor pipe, reduced refrigerant pressure loss, after cold-producing medium is flowed through certain distance, the gaseous refrigerant of HTHP is partially condensated as liquid, enter two-phase section, for guaranteeing the flow velocity of cold-producing medium in U type pipe 1, Jiang Silu merges into three the tunnel, enter secondary channel with three inlets, cold-producing medium is flowed through behind the certain distance, and liquid refrigerant increases, and Jiang Sanlu merges into two-way, enter secondary channel, guarantee to be in the flow velocity of cold-producing medium in U type pipe 1 of two-phase section with two inlets.Last cold-producing medium all is condensed into liquid, enters the liquid monophase field, and merge into one tunnel with two-way this moment, enters the final stage passage that has only an inlet, guarantees to be in the flow velocity of cold-producing medium in U type pipe 1 of liquid monophase field.
In practical application, be not limited to above two embodiment that enumerate, on the chopped-off head passage, more inlet can be set according to the actual needs, also can increase the progression of hot switching path as required.
