[0002] In the existing colleges and universities, the general college laboratories are equipped with a cooling system. On the one hand, the equipment in the laboratory generates heat. In the laboratory, a cooling system is needed to cool the room. However, the cooling system of the existing laboratory has been in a cooling state since it was opened, so that students often feel cold even in summer when they are in class, and they are easy to catch cold, and the cooling system is always It is in the cooling working state, which consumes a lot of power

The invention discloses an indoor automatic cooling control system. The indoor automatic cooling control system comprises a starting normally-open switch, a first contactor, a second contactor, a temperature sensor and a third contactor. One end of the starting normally-open switch is connected with a first electrode of an alternating current power supply. One end of a coil of the first contactor is connected with the other end of the starting normally-open switch, and the other end of the coil of the first contactor is connected with a second electrode of the alternating current power supply. A coil of the second contactor is connected with the coil of the first contactor in parallel, and a normally-open switch of the second contactor is connected with the starting normally-open switch in parallel. The temperature sensor is arranged indoors so as to obtain the indoor temperature. One end of an auxiliary switch of the temperature sensor is connected with the first electrode of the alternating current power supply through a first normally-open switch of the first contactor. One end of a coil of the third contactor is connected with the other end of the auxiliary switch of the temperature sensor, and the other end of the coil of the third contactor is connected with the second electrode of the alternating current power supply. The indoor cooling system is connected with the alternating current power supply through a normally-open switch of the third contactor. According to the system, a lab can be intermittently cooled, and the purpose of saving energy is achieved.
