Out temperature than the second road heat exchanging pipe always to go out temperature 5.5 DEG C high, by number it has been found that heat exchanger by etc. processes shunt after the
Heat exchanging pipe cold medium flux is greater than the second road heat exchanging pipe cold medium flux all the way；
The second road heat exchanging pipe structure is adjusted, each comb group of the second road heat exchanging pipe is than first via heat exchanging pipe
Each comb group lacks a U-tube 2, and the refrigerant flow path length of the second road heat exchanging pipe is relatively shorter than the cold of first via heat exchanging pipe
Matchmaker's operation length, the refrigerant circulation relative increase of the second road heat exchanging pipe, increases defrost heat, improves the change of heat exchanger
Total temperature out of white effect, first via heat exchanging pipe is 0.1 DEG C higher than total temperature out of the second road heat exchanging pipe, by comparison, adjusts
Heat exchanger after whole, first via heat exchanging pipe always goes out temperature and the temperature-difference that always goes out of the second road heat exchanging pipe reduces, and effectively mentions
The defrost ability of exchanger base is risen；
The present embodiment also provides a kind of air conditioner, including above-mentioned heat exchanger, and heat exchanger includes total outlet pipe and multiple groups heat exchanger tube
Road, heat exchanger are connected with the compressor inside air conditioner, and white water when air conditioner defrost is from upper toward flowing down, in equal conditions
Under, refrigerant flows to each group heat exchanging pipe in heat exchanger body 1 by way of branch, and the frost above heat exchanger body 1 relatively holds
Easily change, heat exchanger body defrost is uneven, by adjusting the refrigerant stream of one group of heat exchanging pipe of bottommost in multiple groups heat exchanging pipe
Cheng Changdu, the refrigerant flow path length for making to change one group of heat exchanging pipe of bottommost in multiple groups heat exchanging pipe are less than other each group of heat exchanger tubes
The refrigerant flow path length on road in multiple groups heat exchanging pipe, passes through the flow phase of refrigerant positioned at heat exchanger body bottommost heat exchanging pipe
To increase, the defrost heat of 1 bottom of heat exchanger sheet is increased, defrosting effect is improved, improves the refrigerating capacity of air conditioner.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
