The invention relates to the technical field of temperature adjustment, in particular to a temperature adjusting method and device, a controller, electronic equipment and a temperature adjusting system. The temperature adjusting method comprises the steps that the indoor temperature and the outdoor temperature of a machine room are obtained; a temperature adjusting mode is determined according to the indoor temperature and the outdoor temperature; and the indoor temperature of the machine room is adjusted according to the temperature adjusting mode. Therefore, according to the temperature adjusting method and device, the controller, the electronic equipment and the temperature adjusting system, the corresponding temperature adjusting mode can be flexibly configured so as to adjust the indoor temperature of the machine room, thus energy is saved, and environmental friendliness and science are achieved.
