Background technique
Refrigerant in refrigeration system inner condenser, to medium (air) heat release, makes high temperature and pressure by heat exchanger apparatus
Gaseous refrigerant is condensed into liquid, and refrigerant liquid is cool below the state of condensation temperature, and referred to as liquid is subcooled.By refrigerant
Thermodynamic state figure it is found that throttle before liquid degree of supercooling it is bigger, then throttle after mass dryness fraction it is just smaller, the specific refrigerating effect of circulation
It is just bigger.The degree of supercooling of liquid is small before throttling, and liquid refrigerant will appear flash gas in pipeline flow process, so that into
Refrigerant before throttling set leads to throttle mechanism job insecurity in a two-phase state, and refrigerating efficiency reduces.Therefore, liquid is taken
Body supercooling is advantageous to raising refrigerating capacity and coefficient of refrigerating performance and all the stability of system.General air-conditioning often uses fin casing
The air-cooled heat exchanger of formula once condenses refrigerant, will increase condensation area in order to reach supercooling purpose or is separately provided one
A recooler, so that structure is complicated, higher cost.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide that a kind of structure is simple, implements to hold
Easily, the condenser for machine room air conditioner with pressure supercooling apparatus securely and reliably, while to improve refrigeration system degree of supercooling again not
Increase refrigeration system production cost.
In order to achieve the above objectives, the condenser for machine room air conditioner with pressure supercooling apparatus of the utility model, including successively connect
Gas collecting tube, condensing heat-exchange pipeline, the collector tube, liquid storage device connect, the condensing heat-exchange pipeline is thermally conductive to be threaded through on fin, corresponding
The condensing heat-exchange pipeline, fin set condenser fan, it is characterized in that: the outlet of the liquid storage device is connected with supercooling heat exchanger tube
Road, the supercooling heat exchanging pipe is thermally conductive to be threaded through on the fin.
As optimization technique means: the condenser fan is controlled by fan governor.
As optimization technique means: the fan governor includes temperature sensor, and the fan governor is set to
On pipeline between the collector tube and liquid storage device.
As optimization technique means: inlet shutoff valve is set in the inlet ductwork of the gas collecting tube, the cold heat exchanging pipe
Outlet shutoff valve is set on export pipeline.
The beneficial effects of the utility model are:
1. on the one hand the setting of liquid storage device avoids liquid refrigerant and occupies condenser pipe, to ensure that the cold of condenser
On the other hand solidifying ability ensure that the refrigerant into super-cooling pipeline is liquid, is subcooled refrigerant adequately, while root
The flow of pipeline refrigerant can be balanced according to the variation of operating condition.
2. condensing heat-exchange pipeline and supercooling heat exchanging pipe are on the same fin (coil pipe), compact-sized, be readily produced system
It makes, assembly technology is simple, safe and reliable.
3. the setting of fan governor increases the range of unit operating condition.
4. good effect can be generated to refrigerating capacity, increase Energy Efficiency Ratio etc. is improved by increasing degree of supercooling, and can also ensure system
Cooling system is reliably run for a long time, can be greatly lowered and reduce the work such as the maintenance of air-conditioning, improves production assembly
Working efficiency.
Detailed description of the invention
Fig. 1 is the flow diagram for the condenser for machine room air conditioner that the utility model band forces supercooling apparatus；
Figure label explanation: heat exchanger tube is subcooled in 1- gas collecting tube, 2- condensing heat-exchange pipeline, 3- collector tube, 4- liquid storage device, 5-
Road, 6- fin, 7- condenser fan, 8- fan governor, 9- inlet shutoff valve, 10- outlet shutoff valve.
Specific embodiment
The utility model is described further below in conjunction with Figure of description.
As shown in Figure 1, the band forces the condenser for machine room air conditioner of supercooling apparatus, including sequentially connected gas collecting tube 1, condensation
Heat exchanging pipe 2, collector tube 3, liquid storage device 4, condensing heat-exchange pipeline 2 is thermally conductive to be threaded through on fin 6, corresponding condensing heat-exchange pipeline 2, wing
Piece 6 sets condenser fan 7, and the outlet of liquid storage device 4 is connected with supercooling heat exchanging pipe 5, and heat exchanging pipe 5 is thermally conductive is threaded through fin 6 for supercooling
On.Condenser fan 7 is controlled by fan governor 8.Fan governor 8 includes temperature sensor, and fan governor 8 is set to collector tube
On pipeline between 3 and liquid storage device 4, temperature sensor is for detecting outdoor environment temperature, therefore fan governor 8 can be by
Branch is set up on the pipeline between collector tube 3 and liquid storage device 4.Inlet shutoff valve 9, cold heat exchange are set in the inlet ductwork of gas collecting tube 1
