The invention discloses a temperature control method and device, a storage medium and a data computer room. The method comprises the following steps: acquiring background power data and environmentaldata of a data computer room; determining the distribution (including location distribution and temperature and humidity distribution) of server cabinets in the data computer room according to the background power data and the environmental data; monitoring whether there are local hot spots in the data computer room according to the distribution; and if there are local hot spots, automatically eliminating the local hot spots at the server cabinets. By using the scheme of the invention, the problem of poor security of the data center caused by the emergence of local hot spots in the data centercan be solved, and the security of the data center can be improved.
