How hydraulic calculation calculations are carried out

There are some tasks that need to be solved in order to make a hydraulic calculation of the heating system:

1. Determine the diameter of the pipes in all sections of the system (do not forget to take into account the speed of movement of the heat carrier).
2. Calculate the pressure loss.
3. Solve hydraulic balancing.
4. And, of course, the flow rate of the coolant.

What free programs exist for this?

As you might guess, this program is designed to quickly perform the necessary calculations. First, you need to make all the appropriate settings and select the most suitable items of equipment. Thus, it is possible to create completely new schemes. Moreover, a ready-made scheme can be adjusted as necessary.

This software harmoniously combines both options, allowing you to create original designs and adjust old ones. The program has the widest possibilities regarding hydraulic calculations, from the flow rate of the coolant to the selection of pipes of the required diameter. All the results of your work can be imported into the operating system in any form.

This program is freely available. It allows you to calculate everything you need for systems, regardless of the number of pipes. The essential difference of "Hertz", which favorably distinguishes it from other analogues, is that you can create various projects, both in new buildings and in reconstructed buildings, in which the glycol mixture is the coolant. The program was certified by OOO TsSPS.

Data entry is very convenient, as it is carried out graphically. The results of calculations are visualized in the form of diagrams.

With it, you will calculate the surface or radiator. It consists of a special set of four similar programs. So, let's look at the possibilities of the program:

1. Selection of the pipeline depending on the diameter.
2. Selection of suitable radiators.
3. It determines the height at which the pumps must be placed.
4. Various kinds of calculations of heating surfaces.
5. Determination of the most suitable temperature.

Unlike the previous options, you can download for free only a trial version of the program, which, of course, has some limitations. First of all, in the vast majority of options, you will not only be able to import an image into the operating system, but even print it. In addition, in each individual application there is a kind of limit: three completed projects per one. However, you can modify it an infinite number of times, this is not prohibited. And, finally, finished projects will be saved in a special format, no other version will be able to read such an extension.

As a result, I would like to note that the hydraulic calculation of the heating system is an integral part of the modern control system.In order to choose control valves without having an idea of ​​what is happening on the market at the moment, you will have to make calculations over the entire area of ​​\u200b\u200bthe structure, it is advisable to use the richest possible library. The operation of the entire system will depend on how correct your data will be.

Calculations and work to be done in advance

Hydraulic calculation is the most time-consuming and complex design stage.

• First, the balance of heated rooms and premises is determined.
• Secondly, you need to choose the type of heat exchangers or heaters, as well as arrange them on the plan of the house.
• Thirdly, the calculation of the heating of a private house assumes that a choice has already been made regarding the configuration of the system, types of pipelines and fittings (regulating and shut-off).
• Fourthly, a drawing of the heating system must be made. It is best if it is an axonometric diagram. It should indicate the numbers, the length of the calculated sections and thermal loads.
• Fifthly, the main circulation ring is installed. This is a closed circuit, including successive pipe sections directed to the appliance riser (if a one-pipe system is considered) or to the most distant heater (if a two-pipe system takes place) and back to the heat source.

We also inform you that the database of HERZ fittings in the RAUCAD program has been updated. For questions about obtaining a new database, please contact the engineer of the technical support group of the department of internal engineering systems of the LLC REHAU company, Moscow, tel.: (495) 663-33-88 (ext. 203).

HERZ C.O.

HERZ C.O. is needed for hydraulic calculation of single and heating systems with two pipes and cooling, during the design of new systems, as well as for regulating existing ones in buildings under reconstruction (for example, after building insulation), it has the ability to calculate systems where the heat carrier is glycol mixtures.

The program makes it possible to perform all hydraulic calculations of equipment, within which:

diameters of pipelines are selected;
the water consumption in the designed equipment is analyzed;
pressure losses in the equipment are determined;
the hydraulic resistances of the circulation rings are determined, taking into account the gravitational pressure associated with the cooling of water in pipelines and heat consumers;
the settings of the pressure difference regulators are selected, installed in the places selected by the designer (the base of the risers, branches, etc.);
the required authorities of the thermostatic valves are taken into account;
excess pressure in the circulation rings is reduced by selecting preset valve settings;
the need for equipping an appropriate resistance in terms of hydraulics of the area with the heat consumer is taken into account.

The program uses many solutions that facilitate and improve the work. The most important of them are:

• graphical data entry process;
• presentation of the results of calculations on the scheme and floor plans;
• a developed context-sensitive help system that calls up information about both individual program commands and a hint regarding the input data;
• multi-window environment, it allows you to simultaneously view many types of data, totals, etc.;
• normal cooperation with the printer and plotter, the function of previewing pages before printing and output to the plotter;
• luxurious diagnostics of errors and the function of their automated search, both in the table and on the diagram;
• quick access to the catalog data of pipes, radiators and fittings.

HERZ OZC program

The HERZ OZC program is used to determine the calculated heat loss of individual rooms in a building, as well as the entire building. The calculation is carried out in accordance with the relevant standards. The program does:

• calculation of heat transfer coefficients for walls, floors, roofs and ceilings between the upper floor and the attic;
• calculation of heat losses for individual premises;
• calculation of heat loss of the entire building.

The program uses many solutions that facilitate and improve the work. The most important of them are:

• advanced help system;
• luxurious catalog of building materials;
• the function of automated determination of resistance to heat transfer, resistance of air layers of ceilings between the upper floor and the attic, soil resistance;
• the function of automated creation of the next floors, copying of rooms, and also the choice of rooms, for example, if during the input of data about the room it will be necessary to call another room;
• the option of automated distribution of heat losses from a room with a small need for heating capacity (for example, a corridor) to adjacent rooms, which makes it possible to directly transfer the calculation results to the HERZ C.O.

The program provides an opportunity to calculate the heat loss of huge buildings.

The following are data restrictions:

Limit number of defined fences: 16300 Limit number of layers in one fence: 16300 Limit number of rooms: 16300 Limit number of fences in one room: 16300

The results of heat loss calculations are the output data for the HERZ C.O program used to design district heating systems.

Regarding preliminary work.

Due to the fact that the hydraulic calculation requires a lot of time and effort, we need to first perform some calculations:

1. Determine the balance of rooms and rooms that are heated.
2. Decide on the type of heating equipment and heat exchanger. Arrange them according to the general plan of the building.
3. Before proceeding with the calculation, it is necessary to select pipelines and decide on the configuration of the heating system as a whole.
4. It is necessary to make a drawing of the system, preferably an axonometric diagram. In it, indicate the length of the sections, the numbers and the magnitude of the load.
5. The circulation ring should also be installed in advance.

Important! If the calculation concerns a wooden house, then there are no differences between it and brick, concrete, etc.

will not be.

Hydraulic calculation methods

As we have already said, hydraulic calculation can be done on an online calculator, using a special program, or in an Excel spreadsheet. The first option is suitable even for those who do not understand anything in heat engineering and hydraulics. Naturally, this method can only obtain approximate values, which cannot be used in large and complex projects.

An example of an axonometric diagram.

The software is very expensive and it makes no sense to buy it at a time, but you can make a spreadsheet in Excel without investment. You can perform the calculation using different formulas:

• theoretical hydraulics;
• SNIP 2.04.02-84.

But the calculation method may also differ: specific pressure losses or resistance characteristics. The latter cannot be used for gravity systems with natural coolant circulation. When installing small two-pipe forced circulation heating circuits, it is enough to follow a few simple rules. The main lines are made of polypropylene pipes with an outer diameter of 25 mm. The outlets to the radiators are made of 20 mm pipes. And we wrote about how to choose a pump.
