The invention discloses an indoor temperature control method and device, an air conditioner and a storage medium. The indoor temperature control method includes the steps of obtaining a human skin temperature value and a human skin thermal comfort temperature value, and adjusting the indoor temperature according to the human skin temperature value and the human skin thermal comfort temperature value. When the indoor temperature is adjusted by the air conditioner, the human skin temperature value and the human skin thermal comfort temperature value are obtained first, then the indoor temperature is controlled to be adjusted according to the human skin temperature value and the human skin thermal comfort temperature value, and therefore the indoor temperature automatic adjustment process isrealized, the indoor temperature automatically adapts to the comfortable feeling of a user, and the all-weather comfort of the user is ensured.
