What are the technical requirements for the installation and construction of cold storage projects?

Shanghai Xiangning Refrigeration, focusing on refrigeration, safety and low consumption

The installation of cold storage must adhere to the principle of horizontal-flat-vertical-vertical, and it is necessary to determine the installation location of the equipment (reservoir body, drainage outlet, evaporator, host, condenser, control system, power supply, etc.) according to the drawings and the construction site.

The installation is mainly divided into several large parts: door, ground, library board, unit;

1. The joints between the library board and the library board must be well sealed, and the splicing seam between the two library plates is required to be less than, and at the same time, the structure is required to be firm and reliable. If the roof span is large, the roof should be hoisted;

2. An electric heating device should be buried in the door frame of the low-temperature cold storage door to prevent the sealing strip of the door from being frozen, and electric heating protection devices and safety measures should be provided when electric heating is used;

3. The closer the host position is to the evaporator, the better, and it is easy to maintain, and the heat dissipation is good, such as moving out to the open air, the canopy needs to be installed, the four corners of the main engine need to be placed shockproof gaskets, and the unit needs to be made of brackets or cement platforms, and the ground must be raised by more than 300mm;

4. If the ground is a cement floor with thermal insulation extruded plastic board, it is recommended to lay a layer of corundum on the ground or do self-leveling, which can prevent dust and facilitate the storage of some items and food with high storage requirements;

Many of the installation is not in place, which is often the direct cause of the substandard temperature and high energy consumption of the cold storage. It is recommended that the installation of cold storage should be installed by professional installers, so as to ensure the normal operation of cold storage and facilitate later maintenance.

I talked about it casually, I hope it helps you.

Anhui Kende Refrigeration reminds that the construction of cold storage must first do a good job of thermal insulation to reduce heat loss, and at the same time reduce sun exposure, which is very important for cold storage.

Secondly, the construction of cold storage needs good airtightness to prevent cold air from emanating, because cold storage is very large, so we should pay attention to cold storage;

Another is that the foundation should be done well, because once the foundation is frozen, it is easy to crack, and cracking is not good, so when building fruit cold storage, it is necessary to pay attention, otherwise it is useless.

It's best not to install it yourself, you'll regret it if you cost the device.

1. PreparationThe preliminary preparation includes the formulation of the cold storage installation project plan, and the preparation of the construction site and construction materials. All kinds of materials for cold storage construction are formulated according to customer needs. After formulating the construction plan, sort out the construction lead next to the site that meets the requirements, transport all the installation materials to the construction site, check the quality and model of the materials, and start installing the cold storage after confirming that it is correct.

2. The installation library is reflected in the domestic small and medium-sized cold storage, which is basically a combined cold storage assembled with storage plates, and the large cold storage is mostly civil cold storage. According to the project plan, assemble or build the cold storage body and install the door. The warehouse body should be flat, dense and firm, without hollowing, and its sealing, moisture-proof, anti-freezing and bearing capacity should meet the engineering requirements.

The bin door should be flexible and well sealed. 3. Install refrigeration equipment, cold storage refrigeration system, including evaporator in the warehouse and units outside the warehouse. Therefore, the town bridge equipment should be firmly installed in a position that meets the requirements according to the construction specifications, and there are corresponding protection measures.

4. Install the electronic control system, the cold storage electrical control system includes the electric control box, electric door, lighting and other electrical equipment in the warehouse. The power supply of the cold storage is stable three-phase four-wire (380V), and independent power supply or backup power can be used as needed. The circuit should be reasonably discharged and have corresponding protection measures.

5. Wires and copper pipes should be used to connect the refrigeration system to the cold storage refrigeration unit, the electrical control system and other parts, and the connecting pipes should be tightly connected, and corresponding insulation and protection measures should be taken. 6. Installation of other facilities Due to the different types of goods stored in cold storage and the use of different methods, different cold storage will require additional equipment, such as humidifiers, shelves, conveyor belts and other equipment and facilities that are convenient for users to use cold storage.

The problem you mentioned, in fact, if you really plan to build a cold storage at home, in this case you want to store some food, food or fruit, or a good choice, because now are all out of season sales of things, the price is still more reasonable, suitable, and the profit is relatively large, my home is open cold storage, there are a total of 6 cold storage, so in the early stage of construction and use of many problems need our attention, I can tell you, When building cold storage, first of all, in the periphery of the wall, if it is a cement wall, this time it is necessary to do waterproof and fireproof treatment, waterproof treatment, it is necessary to use glass water and cement spraying treatment, at this time can keep the external moisture can not enter the room, indoor moisture can not be excluded, so that after the decoration template template decoration outside, under normal circumstances, its foaming thickness should be 5 cm, and then spray the foaming agent in the middle of the gap, and the arrogance will be fixed after three hours under normal circumstances. Therefore, the template and mold must be fixed, and it can be dismantled and disassembled after 24 hours, and at the same time as spraying foaming agent, copper pipes must be installed in it, because the copper pipes are compressed and produce strong pressure later, and the feng shui inside can produce a refrigeration effect, I remember that a cold storage next to it uses a hotel, but after about two years of use, this hotel will be blasted, and there is a place for gas leakage and fluoride, so when installing it, you must use the best copper pipe. There is also the thermal insulation effect, the cold storage door must be dealt with, because this is the place where the most personnel are in the situation, if the door cloth insulation effect is done, when you go out to use, you will find that the compressor of the cold storage jumps frequently, and produces a lot of electricity funds between the invisible, which also increases the reserve energy consumption and reduces the profit. The above 2 points must be paid attention to when building cold storage.

I made a cold storage before, which was nice. Ice Wind Refrigeration Gang does.

Hello, the following Kairan refrigeration - professional cold storage installation for you to answer, cold storage installation project needs to pay attention to the details:

1. Preparation. The preparation includes the development of the cold storage installation project plan, the preparation of the construction site and construction materials. The various materials for cold storage construction are formulated according to customer needs.

After formulating the construction plan, sort out the construction site that meets the requirements, transport all the installation materials to the construction site, check the quality and model of the materials, and start installing the cold storage after confirming that it is correct.

The power supply requirement for cold storage is stable three-phase four-wire (380V), and independent power supply or backup power supply can be configured as needed.

The circuit should be discharged reasonably and there should be corresponding protection measures.

5. Connect the refrigeration system. It is necessary to connect the cold storage refrigeration unit, electronic control system and other components with wires and copper pipes, and the connecting pipes should be tightly connected, and there are corresponding thermal insulation and protection measures.

6. Install other facilities. Due to the different types of goods stored in cold storage and the use of different methods, different cold storage will require some additional equipment, such as humidifiers, shelves, conveyor belts and other equipment and facilities that are convenient for users to use cold storage.

7. Debugging cold storage. Once all the components of the cold storage are installed and connected, the cold storage can be started for commissioning. According to the needs of customers, adjust the value of the cold storage, test the cold storage, the cold storage can reach the predetermined temperature, the cooling speed and the cold storage operation is normal, and the cold storage can be delivered.

The cold storage installation unit should also provide cold storage users with training on cold storage use and management knowledge, as well as some after-sales services.

There are two types of small cold storage structures: indoor and outdoor. The body of the small cold storage has good sealing, easy to assemble and disassemble, and the amount of on-site construction and installation is small, labor-saving, and effective. In the long-term cold storage construction process, the construction personnel have also accumulated a lot of rich experience.

Small prefabricated cold storage is widely used, the temperature range of cold storage is 5--23, and the special prefabricated cold storage can reach -30 or less, which can meet the needs of different purposes and is suitable for use in various industries and departments.

Small cold storage, the temperature in the cold storage is 5 -25 degrees, and the cold storage board can be in direct contact with the ground, but the ground should be flat. If a high point is required, then wooden strips can be placed under the cold storage and overhead to enhance ventilation; Channels can also be placed underneath the cold room to enhance ventilation.

At present, polyurethane storage body is mostly selected for prefabricated cold storage: that is, the cold storage storage board is polyurethane rigid foam (PU) as the sandwich, and the metal materials such as plastic-coated steel plate are used as the surface layer, which combines the superior thermal insulation performance and good mechanical strength of the cold storage storage board material. It has the characteristics of long thermal insulation life, simple maintenance, low cost and high strength and light weight, and is one of the best materials for cold storage insulation board selection, and the thickness of cold storage board is generally 150mm and 100mm.

Most of the civil cold storage projects use PU polyurethane foam to make insulation library boards.

The heart of cold storage equipment is the refrigeration unit, the refrigerator and condenser and other equipment are often called the refrigeration unit, the common model of the commonly used small refrigeration unit is the advanced fluorine machine cooling equipment, the fluorine machine cooling equipment is generally small in size, low noise, safe and reliable, high degree of automation, wide range of application, suitable for rural small cold storage refrigeration equipment. Refrigeration units are divided into water-cooled units and air-cooled units. Small cold storage to air cooling unit as the preferred form, it has the advantages of simple, compact, easy to install, easy to operate, less auxiliary equipment, etc., this kind of refrigeration equipment is also easy to see.

It is very important whether the cold storage refrigeration equipment is reasonably configured. This is because the matching of reasonable and reliable refrigeration units can not only meet the requirements of the cold storage refrigeration capacity and cold storage process required by the product, but also save energy and have a low failure rate. Reasonable setting of refrigeration equipment matching cold storage projects, the construction of cold storage may increase investment, but in the long run can save a lot of money and material resources.

Cold storage installation do not be greedy for cheap, looking for the right track cold storage installation manufacturers, there are actual cases, out of the cold storage design plan, cold storage acceptance, cold storage warranty and other after-sales service == Sheng == system == cold
