A kind of antifrost air-conditioner set provided by the utility model, will be welded on the first main line and antifrost heat exchanger
Between inlet ductwork and the export pipeline that is welded between the second main line and antifrost heat exchanger by original four
Two are changed to, by reducing the quantity of inlet ductwork and export pipeline, solves inlet ductwork and the first main line and outlet
The intensive problem of solder joint between pipeline and the second main line.Meanwhile by two inlet ductworks and two export pipeline settings anti-
The same side of frosting heat exchanger shortens the length of entire pipeline, the time needed so as to shorten refrigerant circulation one week, compensation
The import and export pipeline reduces the influence to working efficiency, can guarantee the working efficiency of air-conditioner set.
