The invention discloses an electromagnetic valve, refrigeration equipment and an automobile. The electromagnetic valve comprises a valve body and a piston assembly. The valve body is provided with a valve cavity and a valve port communicated with the valve cavity. The piston assembly is movably arranged in the valve cavity at a valve opening position and a valve closing position, when the piston assembly is located at the valve opening position, the valve port is opened, and when the piston assembly is located at the valve closing position, the valve port is closed; wherein the piston assembly comprises a first piston and a second piston which are arranged in a split mode, the first piston divides the valve cavity into a first valve cavity and a second valve cavity, the valve port is located in the second valve cavity, the first piston is used for opening or closing the valve port, the second piston is arranged on the first piston, and the first piston is used for opening or closing the valve port. The second piston is provided with a pilot valve hole, and the pilot valve hole is used for communicating the first valve cavity with the valve port. The problem that a piston in a traditional electromagnetic valve is poor in universality can be solved.
