If the bathhouse has a high-quality furnace, then a boiler for heating the liquid that will enter the washing room is not required. To do this, you can use the Alfa Laval heat exchanger. Its main function is the heating of the incoming fluid and its return to the hinged tank. That is why, while the "heart" of the bath is burning, the water in the next room will remain hot. After the bath stops drowning, the water drains. This is precisely the rationality of this idea.
Heat exchanger specifications
If you are interested in the manufacturer Alfa Laval, the selection of a heat exchanger from this supplier can be made. How exactly will be described below. Sauna furnaces equipped with a heat exchanger are structures in which there is a space where cold water enters. After her temperature rises, she begins to move through the pipes, advances to the hinged tank or radiators. At the same time, the role of the heat exchanger of the sauna stove consists not only in heating the liquid for the shower, but also in the remote tanks located in the rest room or in the dressing room.
Varieties
If you are interested in the Alfa Laval heat exchanger, then you should consider that you can distinguish two versions of this design. Thus, the heat exchanger may be internal or external. In the first case, the device is a coil, which is launched along the bottom or built into the side of the furnace chamber. The coil is also called a shirt that completely covers the firebox. If we are talking about an external heat exchanger, it is a chimney module, or rather a pipe that is encircled by a sealed container.
Key Features
The Alfa Laval heat exchanger, whatever form it may be, is filled with a liquid, which may be water or antifreeze. The communicating tank is responsible for supplying fluid to the heat exchanger. Capacity is a hinged tank or a battery of water heating. For connection, as a rule, two unions are used, one of them is located below, while the other is above. The principle of operation of the heat exchanger is extremely simple, everything happens due to the circulation of heated water or by connecting a pump that must be powered by electricity.
Tips from experienced stove-makers
Alfa Laval brazed heat exchangers are available in a wide range. Experts recommend choosing an open heating medium heating system 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 the bath is the one whose total pipe length does not exceed 3 meters. As practice shows, this will be enough to place 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 turns out to be less than an inch, otherwise there will be significant resistance to the movement of water, while a bath furnace with a heat exchanger, devoid of a pump, will not be able to distill water. If you have considered the Alfa Laval heat exchanger and decided to make such a unit yourself, then you should be guided by the advice of experienced craftsmen. They recommend making this design using old radiators, which is true if suitable materials were not at hand. You can use car radiators or borrowed from a heating system. They will need to be combined, which will increase the heat transfer area. In the process of work, the use of adapters will be required.
Calculation of the area of the heat exchanger
Experts emphasize that the calculation of the dimensions of the heat exchanger, as a rule, are the same. For example, it takes about 5 kW to heat a traditional room, and it is precisely this amount of energy that a stove with a heat exchanger must give out. As for one square meter of the area of the heat exchanger, this will be approximately 9 kW during the furnace. Undoubtedly, a lot will depend on the location of the boiler with the furnace, as well as the intensity of fuel combustion. However, the boiler capacity after the completion of the furnace process will drop 10 times. That is why the surface area of the heat exchanger must 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 one-time firebox. When considering the Alfa Laval plate heat exchanger, you must consider that the shape of the boiler and furnace can be very different. However, the most popular are those made of stainless pipes, however, those made of two channels are becoming more common.
Alfa Laval M3 heat exchanger specifications
If you paid attention to the Alfa Laval plate heat exchanger, then before purchasing it is worth considering the technical specifications in more detail. If we are talking about the aforementioned model, then the water consumption will be 3, 9 cubic meters. The plates of this heat exchanger variant have a surface area of 0.08 square meters. As for the maximum heat transfer area, it is equivalent to 3.9 square meters. The described model is small in size and very convenient to use, also quite compact in design, it includes a frame that can withstand a maximum pressure of 16 bar. Among other things, the device is equipped with a plate. This model acts as a standard version of a plate-type collapsible heat exchanger, which consists of several plates. Frames are located on both sides. In the production process, the plates are given a corrugated surface, which allows for high-quality heat supply by transferring liquid, which is in countercurrent to each other. In order to prevent water from flowing into one another and not flowing out of the structure, the latter has a number of seals and gaskets that are designed to protect the internal 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 heating equipment to work efficiently. The unit of this series is also called a water heater because of the functions it performs. If we consider in more detail the technical characteristics of a heat exchanger of this kind, we can highlight some dimensions. Namely, the height of the unit, which is equal to 480 millimeters, width (180 millimeters) and a maximum temperature of 180 degrees. The fluid flow rate is 4 kilograms in one second.
The Alfa Laval heat exchanger, the technical characteristics of which will be of interest to every consumer, is presented in a one-way design, the design does not have a supporting foot, which is also called legs. This model is necessarily supplemented with the necessary technical documentation - a passport and an instruction manual. Documents will be required so that users have an idea of the features of the equipment and are able to cope with problems encountered during operation. After all, the buyer will certainly have to maintain, carry out preventive maintenance, clean the system, which will help the effective operation of the device. Once the Alfa Laval heat exchangers have been calculated, you can go to the store. Only in this way you can create a system that will be distinguished by a high efficiency.
Conclusion
It is advisable to purchase the model of the heat exchanger that is recommended by the manufacturer. This will guarantee that the design is suitable for a particular installation, and during operation you will not encounter malfunctions.
