Heat exchanger "Alpha-Laval": technical specifications and calculation

If there is a high-quality oven in the bath, then the boiler for heating the liquid, which will enter the washing, will not be required. For this, you can use the Alfa-Laval heat exchanger. As its main function is the heating of the incoming liquid and its return to the hinged tank. That is why, while the "heart" of the sauna is burning, the water in the next room will remain hot. After the bath stops heating, the water merges. This is precisely the rationality of this idea.

Technical characteristics of the heat exchanger

If you are interested in the Alfa-Laval manufacturer, the selection of a heat exchanger from this supplier can be made. How exactly, will be described below. Bath furnaces, equipped with a heat exchanger, are structures in which there is a space where cold water enters. After her temperature rises, she starts moving through the pipes, advances to the hinged tank or radiators. In this case, the role of the heat exchanger for a bath furnace is not only to heat the liquid for the shower room, but also the external tanks located in the rest room or in the waiting room.

Varieties

If you are interested in the Alfa-Laval heat exchanger, then you should consider that two versions of this design can be distinguished. Thus, the heat exchanger can be internal or external. In the first case, the device is a coil, which is launched on the bottom or integrated into the side of the furnace chamber. The coil is also called a shirt, which completely covers the furnace. If we are talking about an external heat exchanger, it is a chimney module, or rather a pipe that is girded with a sealed container.

Key Features

The heat exchanger Alfa-Laval, whatever it is, is filled with a liquid, which can be water or antifreeze. The reporting capacity is responsible for supplying the liquid to the heat exchanger. Capacity - a hinged tank or a battery of water heating. For connection, as a rule, two fittings are used, one of them is located from below, while the other is from above. The principle of the heat exchanger is extremely simple, it all happens thanks to the circulation of the heated water or by connecting a pump that must be powered by electricity.

Advice of experienced stove-makers

Brazed heat exchangers Alfa-Laval are available in a wide range. Specialists recommend choosing open heating systems in the bath, while the process will not be accompanied by pressure. It is also important that the most effective system for heating the liquid in a bath is one whose total length of pipes does not exceed 3 meters. As practice shows, this will be enough to put the tank directly behind the steam room wall. It is important to pay attention to the thickness of the pipe, it is better if it is less than an inch, otherwise the water movement will be given considerable resistance, while the bath oven with a heat exchanger, devoid of a pump, will not have the ability to distil water. If you have considered the heat exchanger "Alpha-Laval" and decided to make such an assembly yourself, then you should follow the advice of experienced masters. They recommend to make this design using old radiators, which is true if suitable materials were not at hand. You can use automotive radiators or borrowed from a heating system. They will need to be combined, which will increase the heat exchange area. In the course of the work, the use of adapters is required.

Calculation of the area of the heat exchanger

Specialists emphasize that the calculations of the dimensions of the heat exchanger, as a rule, are the same. For example, the heating of a traditional room will require about 5 kW, which is the amount of energy that must be provided by the furnace with a heat exchanger. As for one square meter of heat exchanger area, it will be about 9 kW during the fire. Undoubtedly, much will depend on the location of the boiler with the furnace, as well as the burning rate of the fuel. However, the boiler output will drop 10 times after the completion of the furnace process. That is why the surface area of the heat exchanger should be calculated with some margin, only in this way you will be able to create a system that will be able to maintain a comfortable temperature in all rooms of the bath complex with a two-time or disposable furnace. Considering the plate heat exchanger "Alpha-Laval", you should take into account that the boiler and the furnace can be very different in shape. However, the most popular are those that are made of stainless pipes, but increasingly common are those that are made of two channels.

Characteristics of the Alfa Laval M3 heat exchanger

If you paid attention to the plate heat exchanger Alfa-Laval, then before buying it is worth considering in more detail the technical characteristics. If it is a question of the above-mentioned model, then the water discharge will be 3, 9 cubic meters. Plates of this version of the heat exchanger have a surface area of 0.08 square meters. As for the maximum heat exchange area, it is equivalent to 3.9 square meters. The model described is small in size and very user-friendly, also compact enough, it has a frame that can withstand a maximum head of 16 bar. Among other things, the device is equipped with a plate. This model acts as a standard version of the plate-type split heat exchanger, which consists of several plates. Frames are located on both sides. In the process of production, the plates are given a corrugated surface, which makes it possible to provide quality heat supply by transferring a liquid that is in countercurrent to each other. In order that water does not flow into one another and does not flow out of the structure, the latter has a series of seals and gaskets, which are designed to protect the inner contents from the effects of the external environment.

Positive features of Alfa Laval M3

Alfa-Laval heat exchangers, the characteristics of which will be useful for you to read before visiting the store, are a quality product that allows efficient operation of heating equipment. The unit of this series is also called a water heater because of the functions it performs. If we take a closer look at the technical characteristics of a heat exchanger of this kind, we can distinguish some dimensions. Namely, the height of the unit, which is equal to 480 millimeters, the width (180 millimeters) and the maximum temperature equal to 180 degrees. The liquid consumption is 4 kilograms per second.

The Alfa-Laval heat exchanger, whose technical characteristics will be of interest to each consumer, is presented in a single-stroke version, the design does not have a supporting heel, which is also called the legs. This model is compulsorily supplemented with the necessary technical documentation - a passport and an operating manual. Documents will be required to ensure that users have an idea of the features of the equipment and have managed to cope with the problems encountered in the process of operation. After all, the customer will certainly have to maintain, perform preventive work, clean the system, which will help the device work efficiently. After the calculation of the heat exchangers Alfa-Laval, you can go to the store. Only in this way you can create a system that will have a high coefficient of efficiency.

Conclusion

It is advisable to purchase the heat exchanger model recommended by the manufacturer. This will ensure that the design is suitable for a particular installation, and in the process of operation you will not encounter failures.
