Additional features of sea containers. Block containers and features of ventilation systems in them Supply and exhaust ventilation for containers

In your version, what you said, the main reason for condensation is the insulation inside with cotton wool, the lack of ventilation and the lack of external insulation of the floor of your container. What is going on with you? You have arrived at a frozen house. Turned on the heater. The air temperature began to rise, and since there is no ventilation, the humidity of the air begins to rise. From your breath, from sweat, from the fact that you decided to boil the kettle or cook food. And your floor, or rather what is under the floor, that is, the metal cannot warm up in principle, because it comes into contact with the cold outside air, and secondly, your water-saturated air gets under the floor boards. It comes into contact with cold metal and condenses, in the same place under the floor. That is, under the boards you always have water. Naturally, in such conditions, the boards are simply "obliged to rot." Your walls are in the same position. The air that is inside your container has the ability to get to the cold metal and will always condense on its walls. And the moisture hydrates your cotton pad. From moisture, its thermal properties are reduced by 70-80 percent. That is, you think that your container is insulated, but in fact this is an illusion. Wet wool is no longer a heater.
Just the option of warming the outside will be correct. Condensate will not flow. The colder the air, the less water vapor it contains. That is, the colder, the drier the air. Naturally, the better the ventilation, the less water vapor in the air. The less chance of condensation. The metal insulated from the outside will warm up as the air temperature inside the container rises. That is, its surface will be warm and moisture will not condense on it. And external insulation will protect it from cooling.
If we return to the option of insulating the container from the inside (which is much worse), then the condition must be met when the warmed-up and saturated air will get to the cold metal. That is, the internal insulation must be airtight. And of course, there should not be any cotton insulation options inside. Only heaters that do not let water vapor through and do not get wet. The options are. Spraying with polyurethane foam inside the container: floor, ceiling, walls. That is, a sort of internal thermal module should be obtained, beyond which the access of internal air to the cold outer metal will be absolutely excluded. Second option. Insulation with extruded polystyrene foam. Paste all internal surfaces with XPS sheets, you can glue it with mounting foam. With the same mounting foam, close up possible gaps between the XPS boards. You can lay thick plywood or OSB-3 on the floor. You can plaster the walls and ceiling on a plastic plaster mesh with a thin plaster mortar or putty. Or glue decorative fiberboard. The meaning must be the same. Internal air must in no way be allowed to enter from the inside to the metal of the container. It is necessary to equip the container with a forced-air and exhaust. The inflow is natural, the exhaust is forced. Put a small fan on the wall. The inflow is better through some valve of the type KIV - 125, you can even build a home-made one. Well, either through the vents, or slightly opened windows. But a separate supply valve is better. This is necessary so that you feel normal when you live in a container. There are norms of air exchange at which a person feels comfortable. These norms must be observed in any buildings, apartments, etc. where a person lives or stays for some time.

Do you dream that the house has a healthy microclimate and that no room smells musty and damp? In order for the house to be truly comfortable, even at the design stage, it is necessary to carry out a competent calculation of ventilation.

If this important point is missed during the construction of the house, in the future you will have to solve a number of problems: from removing mold in the bathroom to new repairs and installing an air duct system. Agree, it’s not very pleasant to see black mold nurseries in the kitchen on the windowsill or in the corners of the children’s room, and even plunge into repair work again.

The article presented by us contains useful materials on the calculation of ventilation systems, reference tables. Formulas, illustrative illustrations and a real example for premises for various purposes and a certain area, shown in the video, are given.

With correct calculations and proper installation, the ventilation of the house is carried out in a suitable mode. This means that the air in the premises will be fresh, with normal humidity and without unpleasant odors.

If the opposite picture is observed, for example, constant stuffiness in the bathroom or other negative phenomena, then you need to check the condition of the ventilation system.

Conclusions and useful video on the topic

Roller #1. Useful information on the principles of operation of the ventilation system:

Roller #2. Together with the exhaust air, heat also leaves the home. Here, the calculations of heat losses associated with the operation of the ventilation system are clearly demonstrated:

The correct calculation of ventilation is the basis for its successful functioning and the guarantee of a favorable microclimate in a house or apartment. Knowing the basic parameters on which such calculations are based will allow not only to correctly design the ventilation system during construction, but also to correct its condition if circumstances change.

In the production of a container for placing mining farms or ASICs, we use 20 and 40 foot shipping containers. The walls of the container for ASICs and mining farms inside are insulated with Penoplex 50mm thick and sheathed with stainless steel sheet. This procedure avoids undesirable consequences, such as: heating the container from the outside, the formation of condensate. When used in southern latitudes, we recommend painting the container for ASICs or trusses from video cards in a light color to reduce heat. But taking into account the wishes of the customer, you can paint the container not only in any color, but also leave it in its original form. (Whatever no one would have guessed)). Therefore, placing mining farms in a container, as well as placing ASICs in a container, will have a positive effect on the technical condition of the equipment.

Container algorithm

1. Power supply:

Each rack is equipped with a separate control panel with a voltage relay and an on-time delay relay. In the event of a critical power surge, the voltage relay will turn off the power to the rack. The turn-on time delay relay allows for a phased supply of electricity (for example, after a power outage).

2. Ventilation and recirculation:

The system has a semi-automatic control to maintain the temperature based on the set parameters in the room. Thus, in the winter period of the year, with the help of the recirculation system, we are able to maintain the temperature of the inflow into the room at 10-20 degrees, this temperature, based on experience, is the most suitable for the maximum performance of the equipment. When the cooling system fails or when a critical temperature is reached in the cold aisle, the automation cuts off the power to the racks.

The system has a filter with a degree of purification G3, which allows you to clean the supply air from coarse particles - dust, fluff, insects. This degree of filtration is sufficient for uninterrupted and durable operation of the equipment.

It is also possible to install a cooling system consisting of a heat exchanger (water cooling radiator and a piping unit with a water valve). Design and calculation is carried out on the basis of technical conditions (container installation location, inlet air temperature, humidity, temperature and availability of the required volume of cold water).

3. Burglar alarm and access:

It is a system of door opening sensors and video cameras. Depending on their number, video surveillance is possible both indoors and around the perimeter of the container. Recording on the camcorder is made when motion is detected, with a notification sent. Similarly, a message about unauthorized opening of the door is sent. Cloud video storage.

Access to the premises is carried out by means of an electromagnetic lock with a code and the possibility of opening with a key.

4. Fire alarm:

Consists of a control unit. Smoke and temperature sensors and Zarya 22 gas fire extinguishing modules (HFC 227). When smoke is detected in the room, the automation switches off the power supply to the container, stops the fan, and closes the air supply valve. The fire extinguishing system is activated. A notification is sent to the specified phone numbers.

Sea containers, in fact, are not as simple and "empty" as it might seem at first glance. They have many additional features and configurations. Most people do not know what opportunities they get by purchasing a shipping container. These options can make your container more functional and fit your needs (and at a lower cost, too). Here are some of the more common items that customers choose to add to a container:

Shelves / rack systems

Shelving makes it much easier to organize things in your container. Instead of just unloading everything together, racks and shelves help organize your container's contents for more comfortable use, thus making it easier for you to access more important things, for example.

Ramps

Installing a ramp (board) makes it much easier to load and unload things from your container. If you're constantly storing and removing things from your container, then you'll probably want a container with sides fitted (especially if you're storing heavy items).

Ventilation

Some containers come with roof vents as well as side vents. Depending on the local climate, vents can be a wise decision.

Refrigerators

Refrigerated containers (also called refrigerators) are common in the food industry. If you are storing any type of perishable food, then a refrigerated container is the most suitable option.

double doors

Most containers come with doors on one side only. When operating large containers, it can be extremely difficult to access what you need if you don't have doors on both sides.
