Background technology
Air-conditioner is mainly made up of indoor external heat exchanger, compressor, controller and system pipeline, the air-conditioning of existing more than 2P
Device is more due to the pipeline number connecting indoor and outdoor machine, in order to reduce flow and the pressure loss, needs for coolant to be divided into multiple branch roads,
Cold medium flux in each branch road so can be led to different, in order to solve the problems, such as cold medium flux shunting, typically all can pacify in pipeline
Fill a liquor separator, then be allowed to evenly distributed by adjusting capillary pipe length or U-tube quantity, thus ensureing that system can be preferably
Run.
Existing air-conditioned diverter adopts welding structure, because pipeline fitting is to bend using copper pipe to form, during welding mostly
Easily deviation displacement it is difficult to ensure pipeline fitting assembling corresponding with miscellaneous part, now in order to just install in pipeline fitting
Pipeline fitting local deformation can be made using pipeline fitting for copper pipe and the feature with good ductility, complete to assemble.This kind of side
Formula, the welding requirements to diverter is very high, and current diverter when mounted or after one end time uses it may appear that weld seam
Place's coolant leakage scenarios, directly affect the performance of air-conditioning, and because this kind of situation is located at internal body it is difficult to find, maintenance is very
Trouble.It is additionally, since that the internal installing space of air-conditioning is limited, how multiple pipeline fittings are reasonably arranged, are to be related to they and its
Whether can be good at of his part connects, and other part has enough installing spaces, is also to determine later stage dimension simultaneously
