Water-cooled Split Air Conditioner Unit: Components and Installation

(1) The main structure of a water-cooled split air conditioner is composed of three parts:
① Indoor unit, including evaporator, fan, capillary tube and electrical control part.
② Outdoor unit, including compressor, condenser and condensing fan.
③ Connecting pipe, including refrigerant liquid pipe and suction pipe.

(2) Installation of water-cooled split air conditioning unit
① Determine the drilling position on the wall according to the position of the pipe connection of the indoor unit.

Drill holes according to the drilling size required in the instruction manual, and insert the casing brought randomly into the hole drilled in the wall. The casing should be preferably 10mm longer than the wall hole.
② Unfold the connecting pipe: Before installation, the connecting pipe must be slowly unfolded a small section at a time. Do not pull the connecting pipe vigorously to prevent damage to the connecting pipe due to violent pulling.
③ Bend the connecting pipe according to the predetermined pipeline direction and align the pipe end with the joints of the indoor and outdoor units. Operate carefully when bending. Do not break or bend the pipe. The bending radius of the pipe should be as large as possible, and its bending radius is not less than 100mm.
④ The connecting pipe of indoor and outdoor units adopts the form of a bell mouth joint.

Before connection, a small amount of refrigeration oil should be dropped at the bell mouth joint, and then connected and fastened.
⑤ After connecting the indoor and outdoor units, the air in the pipeline should be removed. When removing the air, the auxiliary valve on the stop valve of the indoor unit or outdoor unit can be used.
⑥ After the air in the connecting pipe is removed, the stop valve can be fully opened for leak detection. Confirm that there is no refrigerant leakage, and then use a refrigerant gas leak detector for leak detection.
⑦ After the above work is completed, insulation material can be wrapped around the pipe nut joint.
