Air conditioning device, battery energy storage equipment and starting control method

The embodiment of the invention discloses an air conditioning device, battery energy storage equipment and a starting control method, and the method comprises the steps that if one of two refrigerating systems is in a working state, the other refrigerating system is determined to be in a starting state, and the two refrigerating systems are configured to share a condensate fan; and whether the condensation pressure and/or condensation temperature values of the two refrigerating systems meet the opening requirement of the condensation fan or not is determined, if the condensation pressure and/or condensation temperature values of the two refrigerating systems meet the opening requirement of the condensation fan, the condensation fan in a closed state is opened, and the refrigerating systems are normally started. In the low-temperature environment, in the starting process of one refrigerating system, the control system controls starting of the condensation fan in the closed state based on the condensation press
