Refrigerant distribution unit for air conditioner

A refrigerant distribution unit for an air conditioner, comprising:

• a pipe unit which distributes a refrigerant from a refrigerant pipe to a plurality of branch refrigerant pipes, the refrigerant pipe being configured to connect to an outdoor unit and the plurality of branch refrigerant pipes being configured to connect to indoor units, each of the plurality of branch refrigerant pipes including an electronic valve and a temperature sensor;
• a main unit that includes an insulator case, an upper case, and a lower case, the main unit storing the pipe unit in such a manner that the pipe unit is at least partially within the insulator case, which is at least partially surrounded by the upper case and the lower case;
• and
• an electric component box which controls the electronic valves and the temperature sensors by connecting the electronic valves with the temperature sensors by cables,
• wherein the insulator case includes a side face where a refrigerant pipe receiving portion for connecting the refrigerant pipe is formed and a side face where a branch refrigerant pipe receiving portion for connecting the plurality of branch refrigerant pipes is formed,
• wherein a cable draw-out recessed portion for drawing out the cables from the pipe unit is formed in one of the side faces of the insulator case where the refrigerant pipe receiving portion and the branch refrigerant pipe receiving portion are formed, and a bottom surface recessed portion for storing the cables is formed in a bottom surface of the insulator case, and
• wherein the upper case includes a first cable draw-out slot formed in a first side face and a second cable draw-out slot formed in a second side face for selectively guiding the cables from the bottom surface recessed portion to a cable guide hole formed in the electric component box, the first and second side faces of the upper case being different from the side faces where the refrigerant pipe receiving portion and the branch refrigerant pipe receiving portion are formed.
