Detailed description of the invention
It should be noted that when not conflicting, the embodiment in the present invention and the feature in embodiment can be mutually combined.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the embodiment of a present invention part, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, all should belong to the scope of protection of the invention.
Fig. 2 and Fig. 3 illustrates the air conditioning system of the present embodiment, and this air conditioning system includes compressor 10 and subcooler 20.Wherein, subcooler 20 includes cooling tube 21 and supercooling tube 22, and cooling tube 21 is for carrying out supercool to supercooling tube 22.Air conditioning system also includes driven compressor plate 50, and driven compressor plate 50 is arranged on the downstream position of cooling tube 21 by heat-exchanging component.When air conditioning system is freezed, coolant all can through subcooler 20, and when coolant enters subcooler 20, the coolant having part enters cooling tube 21, and the coolant of remainder can enter in supercooling tube 22.Coolant in cooling tube 21 can be lowered the temperature to carry out supercool to the coolant in supercooling tube 22 by blood pressure lowering.Coolant in cooling tube 21 is after supercooling tube 22, temperature is still relatively low, driven compressor plate 50 is arranged on by heat-exchanging component the downstream position of cooling tube 21, just can utilize the coolant in cooling tube 21 that driven compressor plate 50 is dispelled the heat, quickly take away the heat on driven compressor plate 50.Therefore, it can ensure the properly functioning of air conditioning system under condition at higher temperature, without the frequency reducing because driven compressor plate 50 temperature is too high occurs, extend the use scope of the high-temperature refrigeration of air conditioning system.In addition, owing to driven compressor plate 50 has been arranged on the downstream position of cooling tube 21, can't produce to interfere to the supercool step of original air conditioning system, thus without the supercool effect affecting subcooler, ensure that the increase of unit mass refrigerating capacity, and then improve refrigerating capacity and coefficient of refrigerating performance.
When air conditioning system heats, can utilize cooling tube 21 that supercooling tube 22 is supercool equally, coolant in cooling tube 21 can walk the heat energy on driven compressor plate 50 through driven compressor plate 50 absorption after supercooling tube 22, and then utilize the heat energy on driven compressor plate 50 to heat, improve the heating efficiency of air conditioning system.
Concrete, as shown in Figures 2 and 3, when air conditioning system is freezed, coolant flows out from compressor 10, enters back in subcooler via outdoor heat exchanger 60, has been divided into two-way before coolant enters subcooler, and a road enters in supercooling tube 22, and another road enters cooling tube 21.Enter the coolant of supercooling tube 22 via carrying out supercool to the coolant in supercooling tube 22 after subcooler valve blood pressure lowering cooling.Coolant in supercooling tube 22 is sent into indoor heat exchanger 70 after being not supercooled and is carried out refrigeration cool-down, finally returns to compressor 10 via gas-liquid separator 90.Switching cross valve 80, air conditioning system is switched to and heats, and coolant flows out from compressor 10, via indoor heat exchanger 70 heat release, subsequently enters subcooler.In like manner, being divided into two-way before coolant enters subcooler, a road enters in supercooling tube 22, and another road enters cooling tube 21, enters the coolant of supercooling tube 22 via carrying out supercool to the coolant in supercooling tube 22 after subcooler valve blood pressure lowering cooling.Coolant in supercooling tube 22 is sent into outdoor heat exchanger 60 after being not supercooled and is absorbed heat, and finally returns to compressor 10 via gas-liquid separator 90.
