Abstract
The utility model provides an air conditioner and a fluoridation device of the air conditioner. The problems that in the prior art, under the status of heating, fluoridation is not possible, forced refrigeration fluoridation operation is troublesome, and right fluoridation quantity can not accurately judged can be solved. The technical scheme is that according to the fluoridation device of the air conditioner, a four-way stop valve comprises a valve body and a sliding valve core in the valve body. A needle valve maintaining port and connection pipes are arranged on the valve body, wherein one of the connection pipes is connected with a four-way valve and the other of the connection pipes is connected with an indoor machine. A connection pipe is further arranged on the valve body and connected with an air suction port of a compressor. When the sliding valve core is opened, a channel of the needle valve maintaining port is communicated with the connection pipe connected with the air suction port of the compressor. Due to the fact that the connection pipe is arranged on the valve body and connected with the air suction port of the compressor and the connection pipe is connected with the air suction port of the compressor, pressure is kept low, and therefore fluoridation can be directly carried out under the status of refrigeration or heating. The fluoridation efficiency is improved and probabilities of misjudging the fluorine quantity under the status of heating are reduced.
