The application belongs to the technical field of automation control and biological sample storage, and discloses a cryopreservation tube suction control system and method, aiming at solving the problems of slow vacuum breaking response, easy sample pollution by external environment and high energy consumption in the adsorption and holding stage of the existing vacuum suction system. The system comprises a power unit, a vacuum energy storage unit, a gas path execution unit, a pressure detection unit and a control unit, adopts a micro-positive pressure cabin as a vacuum breaking clean gas source, realizes fast vacuum breaking through the structure of double vacuum breaking valves in series with a vacuum pump, and utilizes the pre-stored negative pressure energy of a gas storage tank to eliminate the need for continuous operation of the vacuum pump. The control method comprises the processes of pre-vacuumizing, vacuum suction and adsorption, adsorption and holding, vacuum breaking and releasing, and fault grading response. The application effectively improves the release response speed of the cryopreservation tube, eliminates the invasion of external pollutants, significantly reduces the energy consumption of the system, prolongs the service life of the equipment, and is suitable for sample automated access operation in scenes such as biological sample libraries and low-temperature automated storage equipment.

The utility model provides a variable power drying and heating system and clothes processing device, drying and heating system includes air duct chamber, air duct chamber is provided with heating subassembly, is used for the heating of clothes drying airflow, heating subassembly includes at least two heater that sets up along the flow direction of clothes drying airflow in proper order, and the heater is used for the heating of clothes drying airflow. Each heater can be independently started and stopped; the at least two heaters are arranged in the air duct cavity, so that the drying and heating system can have at least three heating combination modes, on one hand, airflow can be heated by a certain heater combination mode all the time in the drying process, and active heating can be kept all the time; according to the drying and heating system, stable heating of airflow by the drying and heating system is ensured, unnecessary fluctuation of the air outlet temperature is avoided, on the other hand, the drying and heating system can provide a larger heating power range and can be adapted to different types of clothes processing devices, and the universality of the drying and heating system on different clothes processing devices is improved.
