Description

Air conditioner refrigerant filling device Technical Field The utility model belongs to the technical field of air conditioner maintenance equipment, and particularly relates to an air conditioner refrigerant filling device. Background With the improvement of living standard, the household air conditioner becomes a necessary electrical appliance of modern families, and the outdoor unit is generally mounted on the outer wall of a building in a hanging manner, so that heat dissipation is facilitated, and indoor space is saved. However, this overhead suspension installation presents challenges when the air conditioner requires a priming operation due to refrigerant leakage or other reasons. In the prior art, technicians need to manually connect and screw up the refrigerant filling pipe and the injection port of the air conditioner outdoor unit under the high-altitude environment. The complex environment limited by high-altitude operation is that operating personnel not only have limited operation space and great operation difficulty, but also easily have the condition that the connection of the injection port is not tight, so that the refrigerant leakage or the low filling efficiency is caused. In addition, the air flow is complex and changeable under the high-altitude environment, even if the initial connection is tight, the strong air flow impact can also loosen the connection part, the refrigerant filling effect is further influenced, and even potential safety hazards can be caused. Therefore, it is needed to develop an air conditioner refrigerant filling device capable of assisting in fixation, so as to solve the problems of unstable connection, inconvenient operation and the like in the process of filling the refrigerant in the high-altitude environment.
