Description

A kind of cold storage with swirling air flow field

technical field

The invention relates to the technical field of freezing and refrigeration of cold chain logistics, in particular to a cold store with a swirling air flow field.

Background technique

The existing cold storage used in the field of cold chain logistics freezing and refrigeration has a cubic structure, and the air flow field formed by the air cooler blows up and down, which may be in the corners of the storage body, where the cold wind cannot blow. The airflow is not evenly organized. At the same time, the humid air in the cold room passes through the air cooler, and water is analyzed, and dew or frost forms on the surface of the evaporator of the air cooler, which affects the heat transfer effect of the evaporator, reduces the heat transfer efficiency, increases the heat transfer temperature difference, and refrigerates. The suction temperature of the compressor decreases, the pressure ratio increases, the power consumption increases, and the performance of the refrigeration system decreases. At the same time, dew and frost on the surface of the evaporator will increase the air flow resistance of the cooler, increase the power consumption of the fan, increase the cooling load of the equipment, and increase the energy consumption.

Contents of the invention

The object of the present invention is to provide a cold storage with swirling air flow field to further improve the operation performance of the refrigeration system and ensure the quality of food, aiming at the technical defects existing in the prior art.

The technical scheme adopted for realizing the object of the present invention is as follows:

A cold store with a swirling air flow field, comprising a storehouse body, the storehouse body comprising a circular roof, a cylindrical wallboard and a circular storehouse floor; a storehouse door frame is opened on the cylindrical wallboard, and the storehouse There is a sealed and fitted warehouse door inside the door frame; a first air cooler and a second air cooler are arranged on the inner side of the cylindrical wall panel opposite to each other and arranged up and down, and the blowing outlets of the first air cooler and the second air cooler are in opposite directions And arranged clockwise; the first cooling fan liquid supply pipe and the first cooling fan return air pipe of the first cooling fan and the second cooling fan liquid supply pipe and the second cooling fan return air pipe of the second cooling fan are respectively Through the cylindrical wallboard, it is connected with the outlet of the throttling and pressure-reducing element of the refrigeration system and the inlet of the refrigeration compressor; a drainage groove is set on the edge of the circular warehouse floor near the cylindrical wallboard, and the storage body A bacteria collector is detachably installed in the central position of the circular top plate.

The drainage groove is provided with a drainage outlet at the bottom position facing the warehouse door, and the location of the drainage outlet is lower than the drainage groove.

The number of air outlets of the first cooling fan and the second cooling fan are the same.

In the present invention, the cold air blown out by the blowing outlets of two cooling fans is used to form a rotating airflow in the storage body. Due to the density, the moisture entrained in the rotating airflow air is thrown to the inner wall of the storage body under the action of centrifugal force, and is discharged through the bottom of the storage body. Bacteria formed in the center of the swirling air flow are absorbed by the bacteria collector when the sink and drain are discharged.

In the cold storage with swirling air flow field of the present invention, the air distribution in the cold room is uniform, the performance of the refrigeration system is improved, the moisture in the air is separated by centrifugal force, the dew condensation and frost on the surface of the evaporator are less, and the heat transfer effect of the evaporator is good. , the air flow resistance of the air cooler is reduced, and the overall energy consumption is reduced.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

As shown in Figure 1-2, a swirling air flow field cold storage includes:

Storage body 1, first cooling fan 2, storage door 3, second cooling fan 4, bacteria collector 5, drainage tank 6, first cooling fan liquid supply pipe 7, first cooling fan return air pipe 8, second cooling fan Liquid supply pipe 9, second air cooler return pipe 10;

The warehouse body 1 is composed of a circular top plate, a cylindrical wall panel and a circular warehouse bottom plate to form a cylindrical sealed structure. One side of the warehouse body 1 is provided with a warehouse door frame directly in front, The storage door 3 sealed and matched in the storage door frame, the second air cooler 4 and the first air cooler 2 are located at different upper and lower positions on the inner wall of the cylindrical wall panel, and are fixed on the inner wall of the cylindrical wall panel and are arranged oppositely. Two air coolers 4 and the air outlets of the first air cooler 2 are arranged in the opposite direction and clockwise, and drainage grooves 6 are set on the edge of the cylindrical wallboard on the bottom of the circular storehouse, and the storage body 1 of the storehouse A bacteria collector 5 is fixed at the central position of the circular top plate;

The first cooling fan liquid supply pipe 7 and the first cooling fan return air pipe 8 of the first cooling fan 2 respectively pass through the cylindrical wallboard to connect with the outlet of the throttling and step-down element of the refrigeration system and the inlet of the refrigeration compressor. The second cooling fan liquid supply pipe 9 and the second cooling fan return air pipe 10 of the second cooling fan 4 respectively pass through the cylindrical wallboard and are connected with the outlet of the throttling and pressure-reducing element of the refrigeration system and the inlet of the refrigeration compressor.

The drain tank 6 is provided with a drain outlet at the bottom position facing the warehouse door 3, the position of the drain outlet is lower than the drain tank 6, and the bacteria collector 5 is detachably installed in the center of the circular top plate, which can be cleaned regularly or replace.

Wherein, the air outlets of the first air cooler 2 and the second air cooler 4 are designed to be arranged up and down, and the number of air outlets of the first air cooler 2 and the second air cooler 4 is the same, which can be adjusted according to the size and cooling capacity of the cold room. to be specific.

Wherein, the bacteria collector 5 is the bacteria collector or device used in the existing cold storage.

When the refrigeration system of the cold storage is in operation, the cold air blown out from the air outlets of the first cooling fan 2 and the second cooling fan 4 forms a rotating air flow in the storage body 1. Due to the density, the moisture entrained in the air is under the action of centrifugal force. Throw it to the inner wall of the storage body, and flow to the drainage tank 6, and discharge through the drain outlet, and the bacteria formed in the center of the rotating air flow are absorbed by the bacteria collector 5.
