Description

An air duct air supply type energy-saving cold storage

technical field

The utility model relates to the refrigeration field of cold storage, in particular to an energy-saving cold storage of an air duct air supply type.

Background technique

In recent years, with the rapid development of the economy and the improvement of people's living standards, the proportion of demand for frozen and refrigerated products is also increasing, and the construction of cold storage will enter the fast lane. This means that the total energy consumption of the cold storage industry will increase significantly in the future. Today, when the country calls for energy conservation and emission reduction, energy-saving transformation of cold storage has become an important issue for the development of the industry.

At present, conventional cold storage generally adopts the method of air cooler or top row pipe to directly supply air to the entire cold storage to realize the cooling process of the goods. However, for the freezing and refrigeration of some special goods (for example, goods that must be stored in an incubator or can be stored in an incubator), the use of conventional cold storage to cool and refrigerate the entire warehouse will inevitably cause a huge waste of energy.

Utility model content

In order to overcome the deficiencies of the above-mentioned prior art, the utility model proposes an air duct air supply type energy-saving cold storage, which only supplies cooling to the space inside the incubator and reduces the energy consumption of the cold storage system.

The utility model adopts following technical scheme to realize:

Including refrigeration unit, air cooler, air supply static pressure box, return air static pressure box, main air supply duct, main return air duct, branch air supply duct, branch return air duct and at least two incubators, each incubator There are two holes on the body, which are respectively connected with the air supply branch pipe and the return air branch pipe; the air supply branch pipe and the return air branch pipe are respectively equipped with electromagnetic air valves; The static plenum and the return air static plenum are connected; the air supply static plenum and the return air static plenum are respectively connected to the outlet and inlet of the air cooler through the main air supply pipe and the main return air pipe, and the refrigeration unit is connected to the air cooler.

The electromagnetic air valve on the branch pipe is in a normally closed state. When the incubator is connected to the air supply branch pipe and the return air branch pipe, the electromagnetic air valve is opened; when the incubator is connected to the branch pipe, the electromagnetic air valve is opened and closed Determined by the temperature value inside the box, when the temperature value is lower than the lower limit of the set temperature, the electromagnetic air valve is closed, and when the temperature value is higher than the upper limit of the set temperature, the electromagnetic air valve is opened; when the incubator is moved out of the cold storage, it is separated from the branch pipeline The moment the electromagnetic damper closes.

The goods that need to be refrigerated are stored in the incubator, and the incubator body is made of heat insulating material and high-strength metal plate.

Different from the conventional method of using air coolers or top row pipes to directly supply air to the entire cold storage, the cooling of the goods in the incubator is realized by sending cold air through the air duct, and the air duct is added with an insulation layer.

Air supply static plenum, return air static plenum plus insulation layer.

The beneficial positive effect of the utility model is:

1. The utility model is an energy-saving cold storage of air duct air supply type, and its air supply mode is completely different from that of conventional cold storage. Conventional cold storage generally uses air coolers or top row pipes to directly cool the entire storage body, but this utility model cold storage uses air ducts to send cold air to the limited space in the insulation box, greatly reducing the cooling space and achieving remarkable energy-saving effects.

2. The utility model is an energy-saving cold storage of an air duct air supply type. In order to improve the cold preservation effect of the pipeline and the plenum, an insulation layer is added to the outer wall. Compared with conventional cold storage, the thermal insulation standard of the storage body itself can be appropriately lowered (or even not required in some special occasions). In this way, the cost of the cold storage project is greatly reduced, and the economic effect is obvious.

3. The utility model is an air duct air supply type energy-saving cold storage, which uses an incubator with uniform structural specifications and standards to store goods, which is convenient for the storage and delivery of goods; especially the combination of the cold storage and automatic storage is convenient for the management of goods .

4. The utility model is an air duct air supply type energy-saving cold storage. Only when the insulation box is connected with the air supply branch pipe and the return air branch pipe, can there be cold air supply, which reduces the energy consumption of the system; when the box is transported During the process, because the box body is made of heat-insulating materials, the cold-preservation effect is remarkable, and it is especially suitable for some long-distance transportation of goods that need to be kept in a low-temperature state.

5. The utility model is an air duct air supply type energy-saving cold storage, which uses a static pressure box to supply cold air to the incubator, which avoids the disadvantage of system pressure imbalance caused by many branch roads during the air supply process.
