A medical contact shock freezer for fast freezing a plurality of individual bags containing a medical liquid, particularly blood plasma, uses refrigeration circuit(s) having an expansion valve switchable between a first throttling configuration which provides a first throttling effect and a second throttling configuration which provides a second, greater, throttling effect.

A freezer system (600) includes a main freezer (602) having exterior walls (604), a floor and a ceiling, together defining a main freezer interior space (606). An interior wall (612) defines an anteroom (610) within the main freezer, and a chill air unit (629) provides chill air to the interior space. A primary personnel access door (608) within the exterior wall accesses the anteroom, while an interior personnel access door (616) within the interior wall accesses the main freezer interior space (606). A product cabinet access door (614) within the interior wall accesses a rapid freeze cabinet (500D) placed within the main freezer interior space adjacent the product cabinet access door. The rapid freeze cabinet includes a cabinet side panel (502D) adjacent to the product cabinet access door, product storage shelves (538A-538D), and a blower (510) to blow chill air across the product storage shelves. The cabinet side panel (502D) has product ingress openings (549A-549D) adjacent the product storage shelves by the product cabinet access door (514).

1. Name of the designed product: direct cooling freezer (laying cabinet with plug-in tray). 2. Use of the designed product: fast freezing of stored goods. 3. Design points of the designed product: in shape. 4. Picture or photo best indicating the design points: perspective view 2.

The application relates to the technical field of refrigeration equipment, and discloses a recommendation method for a refrigeration storage mode, which comprises the following steps: acquiring food images in a refrigeration storage space; determining the space proportion of food according to the food images; and recommending a fast refrigeration storage mode when the space proportion meets a first condition. After a large amount of food materials are stored in the refrigeration equipment, the food images in the current refrigeration equipment are shot to obtain the food space proportion of the current refrigeration equipment, and the fast cooling mode and / or the fast freezing mode are pushed when the food space proportion meets the first condition, so that the most reasonable refrigeration storage mode can be obtained without the user's self-selection, the refrigeration capacity of the refrigeration equipment is strengthened, and the storage quality of food is improved. The application further discloses a recommendation device for the refrigeration storage mode and refrigeration equipment.

A cold storage and a method of operating a cold storage having first cooling unit arranged to cool a compartment and a second cooling unit arranged ensure fast freezing of a substance stored in the compartment. The second cooling unit is operable according to a first, second and third modes of operation involving no, partly, or full contribution from the second cooling unit, wherein shifting between the different modes is determined based on a transition between three different temperature profiles in the compartment.

The invention discloses a site-laboratory aging concrete freeze-thaw damage association method and system, and the method comprises the steps: determining the number of annual freeze-thaw cycles of concrete on site, and converting the number of annual freeze-thaw cycles of a laboratory rapid freezing method; determining the number of freeze-thaw failure threshold cycles of the concrete under a laboratory quick-freezing method; establishing the relationship between the damage factors of the on-site concrete under different service lives and the service lives; calculating damage factors of the laboratory concrete; and corresponding the damage factor of the laboratory concrete to the relationship between the damage factor and the service life of the on-site concrete under different service lives to obtain the concrete service life of the actual on-site member corresponding to the laboratory concrete. According to the method, damage state association and evaluation of the aged concrete on site and the aged concrete prepared in a laboratory are realized, long-term monitoring or destructive sampling is not needed, the period is short, the cost is low, and a scientific basis can be provided for residual life prediction and maintenance opportunity judgment of an existing structure and anti-freezing design of a newly-built structure.

The utility model discloses a medicinal material quick freezing shelf which comprises a shelf body and a plurality of storage structures which are arranged in the shelf body at intervals in the vertical direction, each storage structure comprises two supporting plates, a partition plate and an air pipe, the two supporting plates are fixedly arranged at the two ends of the shelf body respectively, the two ends of the partition plate are movably arranged on the corresponding supporting plates respectively, and the air pipe is arranged in the shelf body. A plurality of evenly-distributed avoiding grooves are formed in the top face of the partition plate, an air hole penetrating through the partition plate is formed in the bottom of each avoiding groove, the multiple air pipes are laid on the top face of the partition plate at intervals, and a plurality of air outlet holes are evenly distributed in the pipe wall of each air pipe. Heat exchange of medicinal materials on the partition plate is accelerated through the air holes evenly distributed in the partition plate, air permeability is good, freezing and insect killing efficiency can be improved, cold air is sprayed to the medicinal materials through the air outlet holes evenly distributed in the air pipe, insect killing is more even, contact between the medicinal materials and the air holes can be reduced through the receding grooves, the air holes are prevented from being blocked, and the service life of the medicinal materials is prolonged. Medicinal material ventilation is facilitated.
