The choice and arrangement of a heat supply system for production workshops at enterprises is not an easy task. This is due to the design features of the workshops, the specifics of technological processes and equipment. An essential criterion for heating any workshop is also compliance with fire safety and sanitary standards. In addition, when heating a shop, one should take into account the efficiency of the corresponding systems, which directly affects the cost of production.
Instructions
Step 1
Before installing a heating system in a workshop, make heat engineering calculations to find out how much heat energy is required to maintain the required temperature in a given room. When calculating, take into account the size of the workshop, the climatic conditions of the area, the location of the building relative to the wind rose and, of course, the technological requirements for the thermal regime. For central Russia, the estimated thermal capacity of the heating system for a workshop with a volume of 170 thousand cubic meters. m. will be about 2 MW.
Step 2
To heat workshops of the specified volume and above, equip the enterprise with its own mini-boiler room. This will make it possible to quickly regulate the air temperature in the premises and reduce the cost of heat supply, which is practically unattainable in conditions of centralized heating, for example, from a CHP.
Step 3
For very large workshop spaces, use air heating. In this case, the air is heated on a water heater or heat generator, and then it is directed through the air ducts to the heated area. The heated air spreads through the room, as a rule, in the form of directed jets from the fans. The most common heating unit that implements this principle is a heat gun, which, if necessary, can be moved around the shop. In the conditions of special industries (for example, chemical ones), this type of heating is the only one allowed.
Step 4
For a more accurate and targeted supply of heat to specific areas of the shop floor, use water heating. To do this, you will need to equip a boiler (heat generator), a system of pipelines and radiators. The water heated in the boiler is driven by the pump through the pipe system and gives off heat to the radiators. Provide a two-pipe wiring system and thermostats - this will allow you to regulate the temperature in each specific heater.
Step 5
If you are planning to further reduce the costs of heating the workshop and increase the controllability of the heating system, use the so-called radiant heating. With this type of heating, infrared emitters are located directly above the heated area. Such systems eliminate the effect of irrational overheating of the upper part of the shop.
Step 6
With all the variety of technical possibilities for heating workshops, choose a specific method based on production conditions and a pre-calculated economic benefit. In some cases, it is more advisable to use mixed types of heating. Such combined schemes are especially good in large workshops, in which different heating conditions are required, determined by the technological features of production.
