Description
Technical field
Air-conditioning heat exchanger cooling technology field is the utility model is related to, 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.In addition, certain degree of supercooling is also prevented from before entering throttling arrangement
Refrigerant in a two-phase state, makes throttle mechanism working stability.General refrigerating plant often utilizes condenser stronger heat exchange in itself
Refrigerant is cooled to below saturation temperature by ability, and the most frequently used air-cooled heat exchanger of air-conditioning is conventional at present has：Fin bushing type etc..
Refrigeration system is to reach the mesh of supercooling, generally use：One increases condensation area；Secondly it is separately provided a supercooling
Device；Cost so is improved, it is also uneconomical.
Utility model content
The purpose of this utility model is in order to overcome the above-mentioned deficiencies of the prior art, there is provided a kind of simple in construction, implementation is held
Easily, safe and reliable refrigeration system supercooling apparatus, do not increase refrigeration system again while improving refrigeration system degree of supercooling and be produced into
This.
The technical solution of the utility model is as follows：
A kind of refrigeration system supercooling apparatus, includes compressor, condensing heat exchanger, restricting element, evaporating heat exchanger and mistake
Cold pipe, the port of export of the compressor are connected with the entrance point of the condensing heat exchanger, the port of export of the restricting element with
The entrance point of the evaporating heat exchanger is connected, and the port of export of the evaporating heat exchanger is connected with the entrance point of the compressor
Connect, it is characterised in that：The port of export of the condensing heat exchanger is connected by connecting tube with the entrance point of the supercooling tube, described
The port of export of supercooling tube is connected by connecting tube with the entrance point of the restricting element.
Described refrigeration system supercooling apparatus, it is characterised in that：Described connecting tube uses copper pipe.
The beneficial effects of the utility model：
1st, the setting of the utility model supercooling tube is reduced to carry out supercooling in itself than general refrigerating plant using condenser
The area of condenser, has saved cost；The setting of supercooling tube improves the flow velocity of condenser bottom tube refrigerant, flow velocity lifting
After will make refrigerant pipe tube internal heat exchange coefficient increase.
2nd, the utility model is simple in construction, be readily produced manufacture, assembly technology is simple, safe and reliable.
3rd, degree of supercooling increase can all produce good effect to the performance for improving whole refrigeration system：Improve refrigerating capacity, increase
Add 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 the utility model structure diagram.
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
It is connected with the entrance point of evaporating heat exchanger 4, 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 passes through connecting tube and section
The entrance point of fluid element 3 is connected.
In the utility model, 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, is discharged into 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 is radiated to be formed
It is cold, increase the degree of supercooling of refrigerant 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 wherein, making room temperature lowering, the refrigerant gas after evaporation is sucked by compressor 5 again,
Such iterative cycles, reach the purpose for reducing room temperature.
Degree of supercooling increase 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 present utility model is the foregoing is only, the utility model is not limited thereto.
