In the scheme provided by the application, the control methods of the heating process and the cooling process are different, specifically, the main regulation and control basis in the heating process is the temperature of the cold accumulation pool, and the basic regulation and control basis in the cooling process is the dew point temperature in the cabinet.
In the present application, it is understood that the temperature allowable range in the cabinet is determined by the first temperature and the second temperature, wherein the set temperature T1 falls within the temperature allowable range.
Compared with the prior art, the embodiment of the application has the beneficial effects that: the internal temperature of the airtight heat-preservation cultural relic storage cabinet is regulated by the cold accumulation pool, so that the temperature control under the windless condition is realized, the adverse effect of the gas flow in the cabinet on the cultural relics is avoided, and meanwhile, the cold accumulation pool is arranged in a sealing mode, and the manual intervention and water supplementing are not needed; in addition, in the cooling process, the dew point is calculated according to the humidity in the airtight heat-preservation cultural relic storage cabinet, and the operation of the refrigerating system is controlled according to the relation between the dew point and the humidity of the cold accumulation pool, so that the change of the humidity in the cabinet in the temperature adjusting process can be reduced, and the influence on cultural relics caused by the change of the humidity is reduced.

In the application, the rotating speed of the water pump is controlled according to the change of the temperature T, so that the rotating speed of the water pump can be matched with the change process of the temperature, and the temperature control is more accurate or stable.
As an optional embodiment of the present application, the controlling the rotation speed of the water pump according to the change of the temperature T includes:
the water pump is started at 2/3 of the maximum rotation speed;
when the temperature T is changed into the first temperature or the second temperature, calculating the change rate of the temperature T to obtain the change rate;
dividing A5 into n sections to obtain n variation values, calculating the variation rate of the temperature T every time the temperature T is increased or decreased by one variation value, and comparing the variation rate with the variation rate obtained by the previous calculation;
if the change rate of the temperature T is increased, the rotation speed of the water pump is reduced by 1/n, or the change rate of the temperature T is reduced, and the rotation speed of the water pump is increased by 1/n;
repeating the process of adjusting the rotating speed of the water pump until the temperature T falls within the range (T1-A5/2, T1+ A5/2);
judging whether the current water pump rotating speed reaches 2/3 of the maximum rotating speed, if so, gradually increasing the water pump rotating speed until the water pump rotating speed reaches the maximum value or the change rate of the temperature T is not less than the initial change rate; if not, gradually reducing the rotation speed of the water pump until the rotation speed of the water pump is smaller than 0.5 times of the maximum value or the change rate of the temperature T is smaller than 0.5 times of the initial change rate.
In the present application, n is a positive integer of 0 to 100, preferably 20 to 50. With the arrangement, the rotation speed of the water pump can be correspondingly adjusted according to the change of the temperature T, so that the temperature can be changed stably. When the temperature falls within the range (T1-A5/2, T1+A5/2), the temperature is relatively close to the set temperature, and two strategies are adopted for adjustment at the moment, one strategy is that the rotating speed is gradually slowed down, so that the temperature adjustment is more accurate; the other is to maintain the rate of temperature change, so that the temperature can be changed to the target temperature at a relatively stable rate by matching the rotating speed with the water temperature (in the application, the water temperature is controlled by the previous steps, so that the rotating speed is controlled on the basis of the matching), the temperature control of the second half section is not more difficult due to the reduction of the temperature difference, the time consumption of each temperature adjustment can be shortened, and the temperature in the cabinet can be quickly restored to the set value. The application adopts a mode of combining two strategies, determines which strategy is adopted according to the water pump rotation speed obtained after the first half section is adjusted, and is the result of the first half section water pump rotation speed adjustment, thereby realizing self-adaptive adjustment of the water pump rotation speed without the situation of reverse adjustment along the change of the water pump rotation speed.
