Shelf freezer with three cold delivery methods

Abstract

The shelf freezing room with three cold transmission methods relates to the field of quick freezing technology, including a freezing box, and is characterized in that: a cooling fan is arranged on the inner side of the top of the freezing box, and both sides of the cooling fan are connected with air supply channels, and the cooling fan The lower end is connected to the return air passage, and the two sides of the return air passage are the freezing space, and there are pipe racks in the freezing space. The cooling fan is a two-way ceiling cooling fan. Supply liquid. The structure design of the invention is reasonable, and in the cold transfer process, the three transfer modes of convection, conduction and radiation are scientifically and effectively combined, so that the ammonia circulation amount, the evaporation amount, and the cooling capacity are increased per unit time, and quick freezing is achieved. The time is shortened and the freezing efficiency is improved.

Description

Technical field: [0001] The invention relates to the technical field of quick freezing, in particular to a shelf freezing room with three cold transfer modes. Background technique: [0002] The freezing room is a kind of compartment where items are quickly frozen into frozen products. In the prior art, the way of liquid supply and steam return in the freezing room adopts one way to supply the liquid to the header, and distribute it freely after reaching the header. In this case, under the condition of unbalanced heat load, some branches Too much liquid supply and insufficient liquid supply in some branches lead to uneven steam return, which in turn leads to the limitation of refrigerant circulation per unit time and low refrigeration efficiency. The traditional freezer does not have strict requirements on wind speed, wind direction, and wind distance, so many convection dead angles are formed in the freezer. Invention content: [0003] The technical problem to be solved ...

In the prior art, the way of liquid supply and steam return in the freezing room adopts one way to supply the liquid to the header, and distribute it freely after reaching the header. In this case, under the condition of unbalanced heat load, some branches Excessive liquid supply and insufficient liquid supply in some branches lead to uneven steam return, which in turn leads to the limitation of refrigerant circulation per unit time and low refrigeration efficiency
