Specific embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
As shown in figure 1, Fig. 1 be a kind of structure for being easy to air-conditioner evacuation to add coolant provided by the utility model and its
The concrete assembling schematic diagram of air-conditioner；Fig. 2 is a kind of knot for being easy to air-conditioner evacuation to add coolant provided by the utility model
A kind of schematic diagram of the specific embodiment of structure；Fig. 3 is that the installation of needle-valve described in the utility model is illustrated.
In specific embodiment as shown in Figure 1 to Figure 3, a kind of structure for being easy to air-conditioner evacuation to add coolant, bag
Include first connecting tube 2 and the second connecting tube 4 of connection 1 indoor set of air-conditioner and off-premises station, first connecting tube 2 and described the
Valving is installed with two connecting tubes 4, and the valving is placed in the indoor set with the off-premises station
Between optional position in first connecting tube 2 or second connecting tube 4, be the air-conditioner by the valving
1 carries out evacuation or plus coolant operation.First connecting tube 2 and second connecting tube 4 are copper pipe.Described first connects
