The sorbing material 62 is connected with the corresponding branch 4 connecting in housing both ends, in this way when liquid refrigerants passes through branch 4,
The adsorbable moisture therein of sorbing material 62 in drying unit 6.Wherein, the sorbing material 62 preferably uses porous silicon glue material
Material.
The shut-off valve for controlling break-make is provided on branch 4.In Fig. 1, the both ends of branch 4 are respectively arranged with first
8 and second shut-off valve 9 of shut-off valve also can only set a shut-off valve and so that branch 4 disconnects certainly.Drying is not needed in refrigerant
When, refrigerant can be made all to pass through from main road 3 by shut-off valve disconnected branches 4.
It needs herein illustratively, in present embodiment, shut-off valve is not provided in main road 3, refrigerant is after condenser 1 comes out
Branch respectively enters main road 3 and branch 4, that is to say, that refrigerant is constantly to enter branch 4 in continuous cyclic process and cause cold
Matchmaker gradually becomes dry.When refrigerant needs dry, it should pass through it will be appreciated that also shut-off valve can be set on main road 3
Shut-off valve disconnects main road 3, and opens branch 4 so that refrigerant passes through from branch 4, after drying, then opens main road 3, and closes
Close branch 4.In present embodiment, it is not provided with shut-off valve on main road 3 and keeps refrigerant from main road 3 by being cold not influence
The original circulating path of matchmaker.
Whether need drying for detection refrigerant, be provided on main road 3 for detect in the refrigerant whether aqueous inspection
Survey unit 5.
Preferably, whether aqueous the detection unit 5 includes the refrigerant passed through for detection that 3 inside of main road is set
What is set on Test paper and main road 3 is able to observe that the observation window 51 of the Test paper.Wherein, observation window 51 can be with
What is set on main road 3 is connected with inside lug boss, and the transparent component of observation is provided on lug boss.The Test paper
It can be attached on the internal face of the transparent component of observation window 51, to facilitate observation.
The Test paper is preferably cobalt chloride chemistry test paper, considerable by observation window when refrigerant passes through detection unit 5
The color change of cobalt chloride chemistry test paper is examined to analyze refrigerant water content, when cobalt chloride chemistry test paper color is gradually become by blue
Red illustrates to contain moisture in refrigerant, and red degree is deeper, illustrates that water content is bigger.It is detected in cobalt chloride chemistry test paper cold
When aqueous in matchmaker, the shut-off valve on branch 4 is opened, refrigerant is enable to enter branch 4, place is dried by drying unit 6
Reason, and when not aqueous in detecting refrigerant or aqueous less, it can disconnected branches 4.
In addition, in present embodiment, the filter element 7 for filtering is additionally provided on branch 4, it is preferable that filtering is single
Member 7 is arranged on the upstream of drying unit 6, that is to say, that and refrigerant first passes through filter element 7 and filters out impurity when by branch 4,
6 adsorption moisture of drying unit.
Filter element 7 includes the filter housings 71 set on branch 4, is filled in filter housings 71 miscellaneous for filtering
The filtering material 72 of matter, the both ends of filter housings 71 are respectively arranged with the second mesh members 73, and the second mesh members 73 are also adopted
With woven wire, filtering material 72 is fixed in filter housings 71 by the second mesh members 73, and causes the filtering
Material 72 can be connected with the branch 4 corresponding to housing both ends, when refrigerant passes through branch 4, can pass through filtering material 72
Filter off impurity therein.Wherein, activated carbon molecular screen material can be used in filtering material 72.
Drying unit 6 and filter element 7 are arranged on branch 4 in present embodiment, and control is set on branch 4
The valve of break-make can disconnect branch 4, when drying unit 6 and filter element 7 do not need to work to replace or clear up filtering
The sorbing material 62 in filtering material 72 and drying unit 6 in unit 7.
The specific work process of air-conditioning system provided by the invention is as follows：
As shown in Figure 1, refrigerant is during Air Conditioning Cycle, by condenser 1 and in condenser 1 heat release be formed as
Liquid, the liquid refrigerants from condenser 1 out enter expansion valve 2 along main road 3, at this time the first shut-off valve 8 and the second shut-off valve 9
It closes, when by main road 3, the cobalt chloride chemistry test paper in detection unit 5 is moistened refrigerant by refrigerant, after observing a period of time,
If it find that blue of the cobalt chloride chemistry test paper color by most gradually becomes red, illustrate to contain moisture in refrigerant, it is hot
When color continues to deepen, open the first shut-off valve 8 and the second shut-off valve 9, refrigerant and enter branch 4, successively filtered unit 7 filter with
And drying unit 6 is dried, and is then out gathered together with the refrigerant in main road 3 from branch 4 and is carried out by expansion valve 2
Adiabatic throttling.So far a complete air conditioner coolant water content detection and dry filter process are completed.
Refrigerant constantly recycles within air-conditioning systems, is detected and by dry single by detection unit 5 in cyclic process
Member 6 is dried, and when observing that the cobalt chloride chemistry test paper in detection unit 5 gradually becomes blue by red, is illustrated in refrigerant
Moisture is less, without being dried again, can close the first shut-off valve 8 and the second shut-off valve 9 so that branch 4 disconnects, refrigerant
All enter expansion valve 2 from main road 3.
The present invention also provides a kind of air conditioner coolant drying means, which can be by as described above empty
Adjusting system is realized.This method comprises the following steps one：
