At the position of finned heat exchanger 11, dotted portion is heat-transfer device 24), heat-transfer device 24 is arranged on the fin of finned heat exchanger 11
Place.
When air-conditioning is heated, it is hot water in the outlet pipeline 13 of case tube heat exchanger 12 in air conditioning system, defrost pipeline
Hot water in outlet pipeline 13 is guided on the heat-transfer device 24 to the fin positioned at finned heat exchanger 11 by water-intake pipe by 20,
Heat-transfer device 24 improves the evaporating temperature of fin position by the temperature of this hot water, to complete to carry out defrost work to fin,
As shown in figure 1, defrost pipeline 20 indicates part in figure thick line.By increasing a defrost pipeline, drain within air-conditioning systems
A small amount of hot water just can complete defrost work, this avoid air conditioning system and run refrigeration mode in defrost, thus avoiding
Impact to indoor temperature, eliminates the fluctuation of air conditioning system ambient temperature in heating operations, it also avoid system input
Power does the idle work of refrigerating operaton, improves running efficiency of system.
And, air conditioning system setting defrost pipeline 20 also not only has advantage described above, in system in heating operations
When cold, defrost pipeline 20 can also be quoted cold water and finned heat exchanger 11 is cooled down, and heat-transfer device 24 now changes in fin
Be equivalent to water-cooled at hot device 11 and add air-cooled, so raising refrigeration efficiency.Meanwhile, in the air conditioning system that can heat hot water, carry out
During water heating, the air conditioning system of the present embodiment equally can reach above-mentioned technique effect, and here is omitted.
In order to lift defrost effect further, defrost pipeline 20 also includes the first collector pipe 21 and the second collector pipe 22,
Heat-transfer device 24 is located between the first collector pipe 21 and the second collector pipe 22, and the first collector pipe 21 is located at the water inlet of defrost pipeline 20
Between end and heat-transfer device 24.The effect of collector pipe is gas-liquid separation and liquid storage, and the first collector pipe 21 and the second collector pipe 22 have
Effect ground avoid inflow heat-transfer device 24 in hot water have bubble it is ensured that in heat-transfer device 24 temperature close with the temperature of hot water
Identical, so that defrost effect is improved.
Meanwhile, the set location of the first collector pipe 21 and the second collector pipe 22 is located at the side of finned heat exchanger 11, fin
The discharge 14 of heat exchanger 11 is provided in the opposite side of the first collector pipe 21.It should be noted that the first collector pipe 21 He
The set location of the second collector pipe 22 is its locus, and the body of finned heat exchanger 11 has relative both sides, and first catchments
Pipe 21 and the second collector pipe 22 are arranged on the body wherein side of finned heat exchanger 11, and the discharge 14 of finned heat exchanger 11 is arranged
In in addition contrary side, the advantage of so setting is not only to avoid the accumulation of collector, can also make in the pipe of defrost pipeline
Current move towards to move towards contrary with the coolant of air conditioning system, and countercurrent flow effect is more preferable.
Defrost pipeline 20 includes strainer valve 23, strainer valve 23 be located at the water inlet end of defrost pipeline 20 and the first collector pipe 21 it
Between.It should be strongly noted that defrost pipeline 20 include the first collector pipe 21, the second collector pipe 22, strainer valve 23 and lead
Thermal 24 is all provided on the water-intake pipe of defrost pipeline 20, and the water inlet end of defrost pipeline 20 and water side are also that it is leaked water
The two ends of pipe.
