The heating area is 15,000 square meters, how to calculate its design heat load?

1. It can be calculated according to the calculation formula of the heating design heat load index q: q=q ao (q, ao are the heat load and construction area of the heating and ventilation system in winter).

q = q 15000 (because the specific heat load of the heating and ventilation system in winter is not given, it can only be calculated up to this step).

Second, the concept of heat load in heating design:

The common heat load estimation indicators for heating design include volume heat load index and area heat load index. Similarity: both are thermal indicators.

Differences: The volumetric heat index refers to the index of the unit heating volume; The area heat index refers to the index per unit area. I think the volumetric thermal index is more appropriate, because it is related to the height of the room, that is, it is more closely related to the area of the envelope.

3. The unit of heating design heat load:

Under the condition of calculating the temperature outside the heating room, in order to maintain the calculating temperature indoors, the heat supplied by the boiler room or other heating facilities per unit time of the unit building area is wm 2.

I don't know what level of education this is!

1 hectare = 10,000 square meters.

1 acre = square meter.

That is, 1 hectare = 15 acres.

1,000 hectares = 15,000 acres.

1,000 hectares = 10,000 acres.

10,000 mu = 1,000 hectares.

When the heating area is 10,000 square meters, the diameter of the heating main network should be determined by calculation, and the general simple calculation is:

The heating floor area is multiplied by the thermal index per unit area (kcal) Calculate the temperature difference of circulating water ( ) and the circulating water flow, and then select the pipe diameter through the circulating water flow rate and the circulating pump head.

It can be seen that the diameter of the circulating water pipe is directly related to the length of the circulating water pipeline, and the longer the pipeline, the larger the pipe diameter required.

For example, the circulating water pipeline is not too long, the flow rate is 78 cubic meters per hour calculated by load, the flow rate is about meters, and DN125 pipes can be used.

How to calculate the heating area of an industrial plant? Heating is very important, and only by ensuring the daily life of each worker can we better improve efficiency. The following is an introduction to how to calculate the heating area of industrial plants.

1. The meaning of heating area, construction area, area in the suite, and heating area.

1.Floor area = effective area + structural area = usable area + auxiliary area + structural area.

Floor area: refers to the product of the outer dimensions of the length and width of the building, multiplied by the number of floors. It consists of a usable area, an auxiliary area, and a structural area.

Usable area: refers to the sum of the net area directly used for production or living in the floor plan of the building.

Ancillary area: refers to the sum of the net area occupied by each floor of the building for auxiliary production or living activities, such as stairs, walkways, toilets, kitchens, etc. in residential buildings.

Structural area: refers to the total area occupied by walls, columns and other structures in the plane of each floor of the building. 2.The area inside the suite.

The area inside the suite, the full name of the building area in the suite, is composed of the following three parts: the usable area in the suite, the wall area in the suite, and the balcony construction area.

The usable area of the house in the suite (GB t is the usable space of the house in the suite.

The area is calculated as the horizontal projection area according to the following provisions:

a.The usable area of the house in the suite is the sum of the space area of the bedroom, living room, hallway, corridor, kitchen, toilet, toilet, storage room, closet and other spaces in the suite.

25,000 square meters of heating area, if in Sichuan, to 120 watts per square meter of reference calorific value.

To make the calculations, a heat load of at least 300 kW is required.

In this case, a ground source heat pump can be used.

Water-source heat pump systems are the most energy-efficient for heating, followed by air energy.

Heating. The use of air can be used for heating, and modular units can be used.

I hope mine can help you, hope.

If there is a usable area on the real estate certificate, the heating fee will be charged according to the usable area, and if the usable area is not indicated, it will be charged according to 75% of the construction area.

This "75 percent" is a calculation formula demonstrated by experts from multiple departments, and if residents have objections to this method of determining the area, they can ask the heating unit to enter the household to measure on the spot, or it can be legally measured by a third party, so as to determine the specific area used.

1 ton boiler = , heating area of 6000 square meters, the heating power required per square meter of heating is 80w h, plus 20% pipeline loss = 100w h 6000 square meters is.

1 ton boiler = , heating area of 6000 square meters, the heating power required per square meter of heating is 80w h, plus 20% pipeline loss = 100w h 6000 square meters is.

Boiler. The boiler is a kind of energy conversion equipment, the energy input to the boiler is chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain thermal energy.

Heating. Regulations stipulate that clean water must be used for hot heating in order to benefit people's health. Clean water must be used for heating in order to benefit the environment. Clean water must be used for heating water to benefit the corporate image of heating.
