Storage temperature and humidity controller with low air exchange rate

The utility model relates to the technical field of temperature and humidity controllers, in particular to a storage temperature and humidity controller with low air exchange rate, which comprises an air blowing component, an adjusting component is mounted on the air inlet side of the air blowing component and comprises an outer box connected with the air blowing component, and the inner part of the outer box is divided into a refrigerating bin, a humidifying bin and a heating bin by partition plates. At least one air inlet is formed in the rear portion of each bin, and an air control funnel is fixed to the position, located at each air inlet, of the inner wall of the outer box. The adjusting assembly used for adjusting the temperature and the humidity is arranged on one side of the air blowing assembly, during use, only external air needs to be adjusted through the adjusting assembly and then fed into the storage room, and the air in the storage room does not need to flow out; and meanwhile, under the action
