Calculation of the heating system, perhaps the most important systems necessary to live in the cottage. Disruptions in electricity and water supplies can be overcome relatively easily. But without the batteries warm in winter will be difficult.
It is important to understand that is efficient and reliable heating system at the design stage. How many batteries must be installed in the room, even not burn from the heat and warmth? How to achieve uniform distribution of heat in the workplace? How to distribute heat in the floors in the House? You must solve all these issues through the correct account for the heating system. First, you need to calculate exactly how much heat is required to maintain a normal temperature + 20-22 degrees cooler period. Calculate this value is very simple-it is the amount of heat they lose the House in the lowest temperature in the street 30-35 . The amount of heat lost home, this is done heating.
Heat loss calculation when taken into account the material and thickness of load-bearing walls, the floor, the ceiling, the existence and characteristics of the attic, basement, doors and Windows performance thermal conductivity. The result is the amount of heat engineering calculation of heat loss of the building . Suppose, as a result of the arithmetic operation to House 100 M2 in Figure 10 kW. This is the amount of heat and the need for heating. This number specifies the capacity of the boiler and heating system-gas, electric or solid fuel. The number of radiators in every room of this building heat loss.
Heating in the House, it should be noted that the warmer the building as a whole and separate components-floor-to-ceiling window, increase savings in heating system (boiler less power, less coolant) and running (less fuel). Therefore, the insulation of the building-one of the most important energy-saving measures when the issue is resolved the first-heat losses are calculated and the capacity of the boiler, a number of batteries, you can proceed to step 2-wire pipe design.
Heating Design Calculations For Sizing Heating Systems Review
The basic principle of the operation of any heating system-principle of circulation of coolant. Radiator-liquid (water and antifreeze), which provide heat from a heat source (boiler) in the room. Gives the thermal energy cooling the radiator back to the boiler, and the cycle repeats. indoor temperature depends on the temperature and speed of the chilled water in the pipes.
Heating in house design errors can lead to the fact that the turnover rate of the water will be lower than it should be. Not for the boiler is operating at full capacity, and other areas is still cold, should take into account indicators such as hydraulic resistance,the necessary strength to overcome the water to reach the final goal. If the flow resistance is high enough, and warm water just doesn’t get there.
In particular, the resistance is influenced by factors such as:
- A section of pipe. What is more, the water passes easily and thus will be more rapid.
- Number of bends and long sections of the heating Chamber-most of them, the worst.
- Temperature and type of fluid. Freezing step with more water resistance.
- Material of the pipe. Plastic pipes have less resistance from the rail of the same diameter.
All this is set up in such a size such as resistance to the flow of the heating system. This value can be calculated using the directories or special programs, but it is better to entrust this work to professionals. Depending on the round shape in determined need and, if necessary, any kind of power. As a general rule, for simple heating systems in homes can do a small area and natural circulation. But the biggest area, number of floors, number of radiators, pipe bends, and should be a force pump.
Let’s sum up. For the design of the heating system, it is necessary to calculate the heat loss from the building, the choice of the boiler with the gearbox. It is also necessary to determine the flow resistance of the future-the pump selection deployed. precise calculation and installation of conscientious objection according to the project concerned heating ensure system reliability and dependability in the coldest winters. how to calculate the heating system? Simple, quick and correct automatically. Even if you know nothing about heat losses, and have never seen formula to calculate, you can do it automatically, quickly and without errors!
