In the logic diagram of FIG. 5, similar to that of FIG. 4, except that in the logic for determining whether to perform a damper closing or opening, t is timed, and then the timed time t is determined to be greater than or equal to a first predetermined time value t1If the first preset time value t is reached1(e.g., 2 minutes) then damper closing is performed; if not, the next step of judgment is carried out, and the judgment temperature T is larger than the first preset temperature T1If the temperature T is higher than the first preset temperature T1(e.g., 50 ℃ C.), then entersNext, judging that the humidity H is larger than a first preset humidity H1If the humidity H is higher than the first preset humidity H1(e.g., 90% relative humidity) then damper closing is performed; the air door can be closed only when the judging conditions of the temperature T and the humidity H are both satisfied, and the timing judgment is returned as long as one of the temperature T and the humidity H is not satisfied; the same applies to the determination of the second preset correlation value of the damper opening.

While embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of application of the invention, and further modifications may readily be effected by those skilled in the art, so that the invention is not limited to the specific details without departing from the general concept defined by the claims and the scope of equivalents.
The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhjhdu (Java Hardware Description Language), and vhigh-Language (Hardware Description Language). It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
