Description
Technical field
The present invention relates to air-conditioning heat exchanger cooling technology field, specifically a kind of refrigeration system supercooling apparatus.
Background technology
Refrigeration system inner refrigerant carries out heat release, the system before refrigeration system throttling by heat exchanger apparatus and medium (air)
Cryogen liquid cooling is subcooled to the state less than condensation temperature, referred to as liquid.From the thermodynamic state figure of refrigerant, before throttling
The degree of supercooling of liquid is bigger, then the mass dryness fraction after throttling is just smaller, and the specific refrigerating effect of circulation is just bigger.Therefore, liquid mistake is taken
Cold is all favourable to improving refrigerating capacity and coefficient of refrigerating performance.Additionally, before certain degree of supercooling is also prevented from entering throttling arrangement
Refrigerant in a two-phase state, makes throttle mechanism working stability.General refrigerating plant is often using the heat exchange that condenser is stronger in itself
Be cooled to refrigerant below saturation temperature by ability, and current the most frequently used air-cooled heat exchanger of air-conditioning is conventional to be had：Fin bushing type etc..
Refrigeration system is the mesh for reaching supercooling, is generally used：One increases condensation area；Secondly being separately provided a supercooling
Device；Cost so is improve, it is also uneconomical.
The content of the invention
The invention aims to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of simple structure, implement easily, peace
Complete reliable refrigeration system supercooling apparatus, refrigeration system production cost is not increased while improving refrigeration system degree of supercooling again.
Technical scheme is as follows：
A kind of refrigeration system supercooling apparatus, include compressor, condensing heat exchanger, restricting element, evaporating heat exchanger and supercooling tube,
The port of export of the compressor is connected with the entrance point of the condensing heat exchanger, the port of export of the restricting element and the steaming
The entrance point for sending out heat exchanger is connected, and the port of export of the evaporating heat exchanger is connected with the entrance point of the compressor, and it is special
Levy and be：The port of export of the condensing heat exchanger is connected by connecting tube with the entrance point of the supercooling tube, the supercooling tube
The port of export be connected with the entrance point of the restricting element by connecting tube.
Described refrigeration system supercooling apparatus, it is characterised in that：Described connecting tube uses copper pipe.
Beneficial effects of the present invention：
1st, the setting of supercooling tube of the present invention be subcooled reducing condenser in itself than general refrigerating plant using condenser
Area, has saved cost；The setting of supercooling tube improves the flow velocity of condenser bottom tube refrigerant, will make after flow velocity lifting
Refrigerant pipe tube internal heat exchange coefficient increases.
2nd, simple structure of the present invention, to be readily produced manufacture, assembly technology simple, safe and reliable.
3rd, degree of supercooling increases can all produce good effect to the performance for improving whole refrigeration system：Improve refrigerating capacity, increase
Plus Energy Efficiency Ratio etc., so as to ensure that refrigeration system is reliably run for a long time, therefore can be greatly lowered and reduce the maintenance of air-conditioning
The work such as maintenance, improve production assembly work efficiency.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Referring to Fig. 1, a kind of refrigeration system supercooling apparatus include compressor 5, condensing heat exchanger 1, restricting element 3, evaporation
Heat exchanger 4 and supercooling tube 2, the port of export of compressor 5 are connected with the entrance point of condensing heat exchanger 1, the port of export of restricting element 3
Entrance point with evaporating heat exchanger 4 is connected, and the port of export of evaporating heat exchanger 4 is connected with the entrance point of compressor 5, and condensation is changed
The port of export of hot device 1 is connected by connecting tube with the entrance point of supercooling tube 2, and the port of export of supercooling tube 2 is by connecting tube and section
The entrance point of fluid element 3 is connected.
In the present invention, connecting tube uses copper pipe.
Low-temperature low-pressure refrigerant gas is compressed into high temperature and high pressure gas by the suction of compressor 5, enters in condensing heat exchanger 1,
Highly pressurised liquid is cooled into, the high temperature high pressure liquid of discharge is collected into supercooling tube 2 again, and condensation again radiates to be formed
It is cold, the degree of supercooling of refrigerant is increased with this, refrigerant liquid is flowed into evaporating heat exchanger 4 after the reducing pressure by regulating flow of restricting element 3,
Low-pressure, liquid refrigerant evaporation endothermic, makes room temperature lowering wherein, and the refrigerant gas after evaporation are sucked by compressor 5 again,
Such iterative cycles, reach the purpose for reducing room temperature.
Degree of supercooling increases can all produce good effect to the performance for improving whole refrigeration system：Improve refrigerating capacity, increase
Energy Efficiency Ratio etc..
Implementing measure of the invention is the foregoing is only, the invention is not limited in this.
