Description
Technical field
The present invention relates to a kind of air conditioner refrigerating technical field, particularly a kind of secondary throttle recooling device that improves air conditioner refrigerating efficient.
Background technology
Existing domestic air conditioner is made up of four parts: i.e. compressor, condenser, throttling arrangement, evaporimeter, connect into the system of a sealing with pipeline, working medium in evaporimeter with the object generation exchange heat that is cooled, absorption be cooled object heat and the gasification, the low-temp low-pressure steam of generation is sucked by compressor, discharges with high pressure after compression, the HTHP gaseous working medium that compressor is discharged is in the condenser medium cooling that is cooled, condense into high temperature high pressure liquid, throttling became the low-temp low-pressure damp steam when high temperature high pressure liquid was flowed through expansion valve, entered evaporimeter, the vaporization refrigeration once more in evaporimeter of low pressure liquid is is wherein so gone round and begun again.Generally, for the degree of supercooling that increases refrigeration working medium reaches the cold excessively purpose of working medium by the condensation area that strengthens condenser often, therefore not only increased cost, and strengthened the volume of air-conditioner.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of easy production, and is simple and reasonable, and the heat exchange efficiency height is used for the secondary throttle recooling device of air-conditioning.Low-temp low-pressure liquid through throttling is cooled off the high temperature high pressure liquid of coming out from condenser again, so not only can increase the degree of supercooling of condenser, thereby and the evaporating temperature that can improve evaporimeter can improve the specific refrigerating effect of air-conditioning and reduce the unit theory and compare merit.
Realize that technical scheme of the present invention is: a kind of secondary throttle recooling device of air-conditioning, parallel with one another with a throttling arrangement on the air conditioner refrigerating loop, comprise capillary, helix tube and flow controller, the front end of described flow controller is connected with condenser, be connected with the rear end of flow controller after the front end parallel connection of an end capillaceous and a throttling arrangement, the other end capillaceous is connected with an end of helix tube, the other end of helix tube be connected to evaporimeter after the rear end of a throttling arrangement is in parallel; And described helix tube is located in the flow controller.By capillary and helix tube part working medium is carried out becoming after the throttling liquid of low-temp low-pressure, enter evaporator evaporation again with mixing again through the high-temperature fluid slightly of a throttling arrangement throttling.
Described flow controller is a hollow cavity, and described helix tube is the spiral copper pipe that is arranged in this hollow cavity, and the two-port of spiral copper pipe is connected with the outside of hollow cavity.
The coaxial center that is arranged on flow controller of described spiral copper pipe, an end of flow controller is provided with the inlet that is connected with condenser, and the other end of flow controller is respectively equipped with the outlet that is connected with capillary with throttling arrangement.
The spiral external diameter 30～40mm of described spiral copper pipe, pitch are 10～15mm.Diameter 5～the 7mm of described spiral copper pipe, wall thickness 0.6mm.
Described flow controller is welded relatively by the copper tube of diameter 50～60mm, wall thickness 0.8mm.
Secondary throttle recooling device of the present invention because its special structural design, through evidence, the air-conditioner refrigerating efficiency of using this device with respect to only once the air-conditioner of throttling improve greatly.Therefore, in existing air-conditioner, by above-mentioned secondary throttle recooling device is set, heat exchange area that can corresponding minimizing condenser, and can improve the coefficient of refrigerating performance of system reliability and air-conditioning, thereby can reduce the production cost and the cost of transportation of air-conditioning greatly, improve the competitiveness of product in market.Simultaneously, secondary throttle recooling device provided by the invention is simple in structure, is easy to make processing.

The specific embodiment
Be described further below in conjunction with the secondary throttle recooling device of the drawings and specific embodiments air-conditioning of the present invention.
This device mainly is made up of copper tube 1, copper tube 2 and spiral copper pipe 3.Wherein copper tube 1 diameter 50mm, long 60mm, wall thickness 0.8mm, copper tube 2 diameter 50mm, long 70mm, wall thickness 0.8mm, launch long 640mm, spiral outward through 40mm at the diameter 6mm of spiral copper pipe 3, wall thickness 0.6mm, and pitch is 15mm.Copper tube 1, copper tube 2 and spiral copper pipe 3 can be welded into the flow controller that has spiral copper pipe 3 shown in Figure 2 easily.Specifying the application of the present invention in air-conditioning referring now to Fig. 1 uses.The flow controller of band spiral copper pipe 3 shown in Figure 2 is welded between condenser tube connector and the evaporimeter, the high-temp liquid that comes out from condenser enters hollow heat exchange cavity in the flow controller through the inlet 6 of flow controller, then from exporting 9,7 flow out, divide the two-way throttling, the working medium that exports 7 places enters in the spiral copper pipe 3 from the port 4 of spiral copper pipe 3 after through capillary 11 throttlings, carry out exchange heat with the high temperature high pressure liquid in the flow controller cavity, flow out the back and export 9 low-temp low-pressure liquid from flow controller and be mixed into slightly that the saturated liquid of high temperature enters evaporator evaporation again from port 5 then through a throttling arrangement 10 (can be capillary or electric expansion valve etc.) throttling.The capillary 11 among the present invention and the specification capillaceous of a throttling arrangement 10 and length are decided on the concrete configuration of air-conditioning.
Above secondary throttle recooling device mainly is that the low temperature saturated liquid by partial throttling reduces the enthalpy of the liquid that comes out from condenser and improves the enthalpy of low-temperature evaporation liquid in the evaporimeter, can improve the refrigerating capacity of unit mass like this, and reduce the operate power of compressor, thereby can improve the Energy Efficiency Ratio of complete machine.In fact this device is exactly a telescoping screw formula high-performance heat exchanger with second throttle.
