The invention discloses a transcritical carbon dioxide air conditioner heat pump PID regulation partition control method and system. The PID regulation partition control method comprises the following steps that the liquid carrying degree of a transcritical carbon dioxide air conditioner heat pump is obtained; if the liquid carrying degree is larger than a preset threshold value of the liquid carrying degree, the actual exhaust pressure of a compressor, the target exhaust pressure of the compressor, the actual air supply temperature of a compartment and the target air supply temperature of the compartment are obtained; and zone control is conducted based on the difference value between the actual exhaust pressure of the compressor and the target exhaust pressure of the compressor and the difference value between the actual air supply temperature of the compartment and the target air supply temperature of the compartment. The invention particularly provides a compressor and electronic expansion valve control logic of a transcritical carbon dioxide air conditioner heat pump, which can solve the problem of system imbalance caused by PID (Proportion Integration Differentiation) adjustment during operation in a heat pump mode in the prior art, and can ensure the safety and enable the system to have a higher energy efficiency ratio at the same time.
