What details should be paid attention to when installing cold storage, Anhui Kende Refrigeration pointed out that the volume of cold storage must be considered when installing small cold storage, the size of cold storage should actually be designed according to the agricultural products we store, this capacity is actually calculated according to the volume stacked in the cold storage, and the distance between the aisles between the rows should also be added, and the distance between the goods pile and the wall and the ceiling should also be considered. After determining the capacity of small cold storage, we can determine what length and height the cold storage should have during the design process.

At the same time, when installing a small cold storage, we should consider the choice of insulation materials, which not only need to be equipped with good thermal insulation performance, but also should be responsible for the principle of economy and practicality.

1.Cold storage volume.

When installing small cold storage, we must consider the volume of cold storage, the size of cold storage should actually be designed according to the agricultural products we store, this capacity is actually calculated according to the volume stacked in the cold storage, and the distance between the aisles should also be added, and the distance between the goods pile and the wall and ceiling should also be considered.

2.Location selection for small cold storage.

When designing a small cold storage, you should consider the nearby outbuildings, such as packing and finishing rooms, tool storage, workshops, loading and unloading stations. According to the nature of use, small cold storage can be divided into retail cold storage, productive cold storage, distribution cold storage, productive cold storage is generally concentrated in the place where the supply is relatively concentrated, so we need to consider whether the surrounding traffic is convenient, the surrounding cold storage is best equipped with good drainage conditions, Kuhua refrigeration suggests that the bottom of the small cold storage is best set up compartment, for small cold storage, it is very important to keep dry.

3.Selection of insulation materials.

When installing a small cold storage, we should consider the choice of insulation materials, which not only need to be equipped with good thermal insulation performance, but also should be responsible for the principle of economy and practicality.

4.How to choose a cooling system for small cold storage installation?

When installing small cold storage, it is recommended to consider the cold storage compressor and evaporator when choosing the cooling system, in general, the small cold storage will choose a fully enclosed compressor, and most of the medium-sized cold storage are semi-enclosed compressors, which are the details we need to consider in the installation process of small cold storage.

5.Refrigeration compressor options.

In the process of small cold storage installation, the selection of refrigeration devices should also be considered, and the refrigeration compressor is generally selected according to the capacity and quantity of cold storage equipment when choosing, and the refrigeration parameters should also be taken into account.

1. Installation of library board.

2. Installation requirements for air coolers.

3. What kind of refrigeration unit should be installed before the installation of the refrigeration unit, generally the small cold storage is installed with fully enclosed refrigeration units, and the medium and large cold storage is installed with semi-enclosed refrigeration units. After the refrigeration unit installation is completed, it needs to be safe.

Install a matching oil separator and add the right amount of oil, and if the preset temperature of the cold room is below -15, you should also add refrigeration oil. In addition, a shock-absorbing rubber seat should be installed at the bottom of the compressor, and a certain dimension should be left around.

Repair space, easy to repair and inspect. Professional cold storage engineering companies have a certain degree of attention to the overall layout of the unit, and the color should be unified, and the installation structure of each unit model should be consistent.

4. Pipeline installation.

5. Installation of electrical control system.

6. Cold storage commissioning.

1.The cold storage must be sealed well to prevent the leakage of cold air.

2.Prepare more foam, or empty buckets with sealed lids, and put these things in the cold storage when there are few things, and fill up the space in the cold storage, which will save electricity.

3.Every time you open the cold storage door, try to shorten the time, and try to close the door as soon as possible to prevent hot air from entering.

4.When the staff enters, they should wear warm cotton clothing, which can also prevent the heat of the human body from escaping into the warehouse.

1.The cold storage should be removed from the heating utensils. During the installation of cold storage, it will affect the cooling efficiency of cold storage equipment in hot places, and it will also damage cold storage.

2.The drainage system in the cold storage is discharged by draining pipes, and water will be discharged frequently, so try to direct the drainage to a place where it can flow smoothly.

3.Pinghuai Xinheng hole (pressure equalizing valve, also known as balance window), do not install in a conspicuous place and sleepy air outlet stand, the height is 200mm opening on the upper part of the cold storage stand. All parts that run through the cold storage board, and the gap between the cold storage board and the parts need to be sealed with sealant.

4.Wire discharge: In addition to being tied with an air conditioning cable tie, all wires need to be protected by corrugated hoses or wiring ducts.

5.The cooler installation radiator of the cold storage unit is the closer the radiator is placed to the cold storage unit, the better, it is best to be in the upper position of the cold storage unit, the radiator installation position has the best heat dissipation environment, the air suction outlet can not be against the air outlet of other equipment, especially the oily gas, the air outlet can not be short-circuited and facing other windows (especially resident windows) and equipment, it should be 2m high from the ground, and the installation level is firm.

6.All copper pipes of the cold storage unit should be separated by the insulation pipe and the wires in the same direction and wrapped together with the air conditioning tie, and the pipeline should be straightened as far as possible and fixed in sections.

7.The cold storage is installed in a strong, stable place. If there is no leveling place, fix it.

8.The location of the cold storage unit installed in the cold storage unit is as close to the evaporator as possible, and it is easy to maintain, and the heat dissipation is good.

9.The refrigeration system of the cold storage construction is connected to the condenser and evaporator of the cold storage unit in the factory are pressed and sealed, so when opening, there should be pressure, and whether there is a leak, and the factory copper pipe should have dust sealing measures at both ends, and it should be sealed at any time during construction to prevent dust from entering the pipe.

The design and installation of cold storage should pay attention to the following issues:

1. Selection of thermal insulation materials. This is very important for the quality of cold storage installation, and the selection of cold storage insulation materials must be adapted to local conditions, which must not only have good thermal insulation performance, but also be economical and practical. There are several types of thermal insulation materials, one can be sprayed with polyurethane foam, and the material is sprayed directly into the already built brick or concrete warehouse, which is both moisture-proof and heat-insulating after shaping.

The thermal insulation material sector includes polyurethane, polystyrene, etc. Polyurethane does not absorb water and has good thermal insulation, but the cost is higher in the current cold storage installation market; Polyphenylene resin is highly absorbent, has poor thermal insulation, and is currently less expensive in the cold storage installation market.

2. Strengthen the design review of construction drawings of cold storage projects. Design is the leader of engineering construction, and it will play an important role in ensuring the safety of the structure and saving investment. Combined with the engineering problems of previous years, all the professional construction drawing design review attention and implementation rules.

In order to reduce and eliminate the various problems that may arise during the construction design phase, improve the approval rate of drawing review.

3. Strengthen technical training. The design institute was faced with a complex variety of buildings and demand projects, and there were many technical difficulties. Depending on some profile and development in the standard design or technical assembly, it will play a good role in ensuring the quality of the design.

The suggestions of the management department, with reference to the national civil building design technical measures, make a correct understanding of the problems of engineering design and the technical links that are most likely to make mistakes, and formulate various professional and unified technical measures. This will play an important role in improving the quality of design and improving the level of design.

4. Increase research work. Due to the reform of the current wall materials, a huge number of hybrid structures in the design of wide construction have many new problems to study. The increasingly complex functions of high-rise buildings need to be adjusted and continuously supplemented.

In addition, some new issues still need to be studied. KFC has rich experience in cold storage design, you can go and have a look.

Hello, need to take into account safety, energy saving, convenience, etc.
