Abstract
The utility model provides a multi-row pipe evaporator, particularly the improved technique used for reducing the evaporator power consumption. The utility model comprises cooling fins, allotter thin pipes, afflux pipes and multiple rows of coolant pipes which are connected between the allotter thin pipes and the afflux pipes and are penetrated in the cooling fins, wherein the coolant pipes comprise two or more than two heat exchange systems which are mutually independent. The coolant pipes in different heat exchange systems are in staggered arrangement, and multi-direction joints are arranged among the coolant pipes of the same heat exchange system. The coolant in each system enters from the coolant pipes on the upper part of the cooling fins through the allotter thin pipes, flows from the coolant pipes on the lower part of the cooling fins, and enters the respective afflux pipe. The design reduces the flow resistance of the coolant and improves the heat exchange efficiency of the evaporator, and the evaporator can efficiently use all heat exchange area when the single system is unloaded. In addition, the heat exchange in the negative direction inside the evaporator can be decreased, the coolant exchanges 'counter-flow heat' with the air through the evaporator to improve the heat exchange efficiency of the evaporator, and accordingly, the power efficiency ratio and the effectiveness coefficient are improved.
Description
Technical field
The utility model belongs to air-conditioner and makes the field, is specifically related to the improvement technology of multi coil road evaporimeter in a kind of air-conditioner.
Technical background
The power-saving technology of current air-conditioner and effect more and more are subjected to people and pay close attention to.For improving the adjustment ability of air-conditioner, adopt the method that increases evaporimeter and condenser heat exchange area usually.Existing air-conditioner generally adopts two row or multi-row evaporimeter and condenser.Common two row or multi-row heat exchange manifold layout employing two is advanced one and is gone out or advance more a direct shunting mode that goes out, can not solve the reverse heat-exchange of heat exchanger inside well, overall heat exchange weak effect, efficient are low, thereby cause air-conditioner when cooling and warming, Energy Efficiency Ratio and usefulness coefficient are all lower, power consumption is big, and the economy that has hindered air-conditioning to use does not meet the requirement of the whole world for energy-saving consumption-reducing yet.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of and reduce the refrigerant flow resistance, reduce the dual system multi coil road evaporimeter of the reverse heat-exchange of evaporimeter inside, and effectively utilize whole heat exchange areas during single system in unloading, cut down the consumption of energy, improve heat exchange efficiency.
The technical scheme of the utility model multi coil road evaporimeter is: a kind of multi coil road evaporimeter, comprise cooling fin, distributor tubule, manifold trunk and be connected between distributor tubule and the manifold trunk and be arranged in many rows refrigerant pipeline in the cooling fin, it is characterized in that described refrigerant pipeline comprises the heat-exchange system that two or more are separate.The refrigerant of each system enters, flows out the manifold trunk that enters separately from the refrigerant pipeline of cooling fin bottom from the refrigerant pipeline on cooling fin top by the distributor tubule.
The intrasystem refrigerant pipeline of described various heat exchange interlaced arrangement.
Be provided with multidirectional connector between the refrigerant pipeline of described same heat-exchange system, reduce the refrigerant flow resistance.
In general, described multidirectional connector is threeway; Described refrigerant pipeline is four comb roads.
The beneficial effects of the utility model are, this novel multi coil road evaporimeter is arranged and type of attachment by changing traditional refrigerant pipeline, compared with prior art, owing between the refrigerant pipeline, be provided with threeway, can reduce the refrigerant flow resistance, improve the heat exchange efficiency of evaporimeter.And, whole evaporimeter is divided into a plurality of heat-exchange systems, the refrigerant pipeline interlaced arrangement of various heat exchange system makes evaporimeter effectively to utilize whole heat exchange areas when the unloading single system.In a word, this design can reduce the reverse heat-exchange of evaporimeter inside, makes refrigerant by evaporimeter and air " countercurrent flow ", improves the heat exchange efficiency of evaporimeter, thereby improves Energy Efficiency Ratio and usefulness coefficient.When evaporimeter unloading single system, effect is more obvious.
Description of drawings
Below in conjunction with the drawings and the specific embodiments multi coil of the present utility model road evaporimeter is further described:
Accompanying drawing 1 flows to schematic diagram for the refrigerant of the utility model multi coil road evaporimeter;
Accompanying drawing 2 is the line arrangement schematic diagram of the utility model multi coil road evaporimeter.
The specific embodiment
As accompanying drawing 1, shown in Figure 2, the multi coil road evaporimeter in the present embodiment comprises cooling fin 1 and is arranged in four in the cooling fin 1 arranges refrigerant pipelines 2, also comprises thin 3 and two manifold trunks 5 of two column of dispensers.Refrigerant pipeline 2 is divided into I heat-exchange system 6 and II heat-exchange system 7, and distributor tubule 3 is connected with II heat-exchange system 7 with I heat-exchange system 6 respectively with manifold trunk 5, and these two systems are separate, but their refrigerant pipeline 2 interlaced arrangement.The distributor tubule 3 of refrigerant by separately enters, flows out from the refrigerant pipeline 2 of cooling fin 1 bottom from the refrigerant pipeline 2 on cooling fin 1 top, enters manifold trunk 5 separately.Each column of dispensers tubule 3 comprises three pipes, and the distributor tubule 3 of two systems is cross-linked respectively to the port of first row's refrigerant pipeline 2.Between first row's refrigerant pipeline 2 and second row's refrigerant pipeline 2, be respectively equipped with three one road refrigerant is divided into the threeway 4 of two-way, when the 2nd row, the refrigerant pipeline is divided into 6 the tunnel, reduce the refrigerant flow resistance with this.Refrigerant in the I heat-exchange system 6 of arranged crosswise and the II heat-exchange system 7 enters by the refrigerant pipeline 2 of distributor tubule 3 from first row, part evaporation back is by threeway 4, reduce the refrigerant flow resistance, progressively evaporation, refrigerant pipeline 2 from the 4th row flows out evaporimeter at last, enters two manifold trunks 5 arranging up and down.In the refrigerant flow process, refrigerant flows from top to bottom, progressively evaporation, and the volume of refrigerant rises with flow process.By each road refrigerant being divided into the threeway 4 of two-way, reduce the refrigerant flow resistance in part evaporation back, effectively utilize whole heat exchange areas.
Because in the refrigerant flow process, the temperature of refrigerant also rises with flow process.Air is in the dirty pervaporation device of the effect of aerofoil fan (not shown), and temperature descends, and in air and refrigerant heat transfer process, forms " countercurrent flow ", improves Energy Efficiency Ratio and usefulness coefficient.
And I heat-exchange system 6 and II heat-exchange system 7 arranged crosswise when the dual system unloading becomes single system, can effectively be utilized whole heat exchange areas, increase along the journey mean temperature difference, thus the heat exchange efficiency of raising evaporimeter.
In practical application, be not limited to the above embodiment of enumerating, row's number of refrigerant pipeline, the quantity of heat-exchange system and threeway the position is set and quantity all can change according to the actual needs.
