How many square meters is Midea air conditioner 1.5 low-pressure pipe? Nanchang air-condition maintenance

Pipe 10 mm or so, which can manage rooms of19m2 or so. The low-pressure pipe of constant-frequency air conditioner has a larger diameter, ranging from12mm to13mm, while the low-pressure pipe of variable-frequency air conditioner has a smaller diameter, ranging from 9 ~ 10mm. The low-pressure pipe is a thick pipe, so its diameter is about 4 ~ 5mm larger than that of the high-pressure pipe. The sizes of low-pressure pipes and high-pressure pipes vary greatly with different specifications of air conditioners. 1, 1.5 air conditioning is suitable for rooms from 19 square meters to 20 square meters. If you turn on the refrigeration, you can ensure that there is cold air in every corner of the room. If the room is large, the cold air diffuses and the slow cooling effect is poor. If the room is small, the cold air diffuses very quickly, and the lower body temperature is lower at similar temperature. 2. The high-pressure pipe of air conditioner is a thinner pipe, and the low-pressure pipe is a thicker pipe. Generally, the diameter of low-pressure pipe is between 9 ~ 10mm, and the diameter of high-pressure pipe is between 6 ~ 7mm, with a difference of 3 ~ 4mm. The pipe paths of two air conditioners are the same as those of 1.5 air conditioners, and the high-pressure pipe diameters of three and four air conditioners are 2 mm different, with the same diameter of thick pipes. 3. Refrigerant liquid flows out from the high-pressure pipe and refrigerant gas flows out from the low-pressure pipe, which represents two forms of refrigerant. The process of changing refrigerant from liquid to gas is the process of heat conversion.
