The application discloses a multi-connected system and a control method of an electronic injection enthalpy expansion valve during heating of the multi-connected system. The multi-connected system is started and enters a soft start stage. In the soft start stage, the electronic injection enthalpy expansion valve is closed, and after the multi-connected system runs for a time length A, the multi-connected system enters a normal control stage. In the normal control stage, when the frequency of the compressor reaches B, the multi-connected system determines whether the electronic injection enthalpy expansion valve is opened according to the ambient temperature and the indoor unit load rate, and the initial opening degree of the electronic injection enthalpy expansion valve after being opened. If the electronic injection enthalpy expansion valve is opened and maintained for a time length C, the multi-connected system determines a target high-pressure saturated temperature according to the current ambient temperature, and then adjusts the opening degree of the electronic injection enthalpy expansion valve according to the difference between the target high-pressure saturated temperature and the actual high-pressure saturated temperature. In this way, the electronic injection enthalpy expansion valve can be adjusted from multiple aspects, the state of the multi-connected system is detected in real time during the opening of the electronic injection enthalpy expansion valve, and the customer comfort and the system reliability are improved.
