When the multi split air conditioner installed with long pipe run in low temperature ambient, the heating capacity and the outlet air temperature caused serious attenuation. In this paper, by proper amen-ding the system sub cooling degree to improve the heating capacity is discussed, and the outlet air temperature become more comfortable by controlling the fan speed.
