Heating of the soil is carried out in the following industries: Agriculture,greenhouse heating of the soil;Industry,heating under
freezer soil;Construction,heating lawns,soccer fields, and other areas.There are different methods of soil heating in greenhouses. We propose to do this by using the heating cable. If You take advantage of this offer will receive advantages: relatively small costs during construction; permanent readiness of the system for operation; automatic operation, does not require human intervention; easy-to-use management; the heat is evenly distributed over the entire area; plants grow faster; the harvest season lasts longer; yields more; you can grow plants that normally grow only in very hot exotic climate. Cable heating system for the greenhouse soil used to increase the vegetation period. Vegetables and other plants can be grown all year round, not just in a few months. The heating of greenhouses - the opportunity to grow vegetables even in winter. The main thing - to choose the correct power and heating. If it is too large, may cause dryness of the soil, the roots. The temperature control is performed by means of thermostats. For different crops, the optimum soil temperature is in the range of 15-25 degrees, for peat pots and beds about 30 degrees.
Heating of the soil: the Industry. System heating cable in this direction provides protection against freezing of the soil under industrial refrigerators in the freezer artificial rinks. In the process of industrial refrigeration plants must be kept low temperature, in this regard, the design of the floor gradually freezes. After a certain time is the soil freezing. Are the moisture in the soil freezes and leads to swelling of the soil, which destroys any Foundation. This task can only warms the bottom of the freezer with heating cables. Heating cable generates heat shield, protecting the penetration of cold into the soil under the freezer. The heating cable is installed under the insulation layer. Heating capacity is about 15-20 watts/sq m Integral cable heating special heating cables for industrial use,has high mechanical strength,resistance to thermal overloads. The management system is a fully automatic mode, can usually be programmed to maintain the temperature of the thermal layer in the range +3...+5°C. This system meets the highest demands for quality heating cables work performed, upon the occurrence of defects may require large material costs.
Heating of the soil: Football fields and lawns. The game features a soccer field in warm and cold seasons are very different. If You want in autumn and spring game passed without complications, you should use the heating system. They are attached to fields with artificial grass and natural, but for different reasons. On fields with artificial heating is required for melting snow and drying the surface, in the fields with natural grass so that the grass grew faster. This system will maintain a stable temperature of 0-20 With on the surface: Q = a*F*(to-tH) where a is the coefficient
heat loss to the environment from the surface of the field; F is the area that needs to be warmed up; t0 is the surface temperature; tH - ambient temperature. The temperature at the boundary layer can be defined as: t = to+ Q/F*D/l where D is the layer thickness, and I is the effective conductivity of the layer. The speed and direction of the wind, the grass height affect the coefficient
heat, snow and moisture condition of the layers on the thermal conductivity. There are 2 main ways to install heating systems field: 1. The heating cable. Advantages: - uniform heating of the entire field; - it is possible to divide the heater into several zones, if you want multi-use fields; - do not need to do a repair coating; heating section fails, will not result in special material and time costs; - the power supply does not need to upgrade, this is quite suitable existing; - automatic operation of the system; - maintenance of the heating system may be involved in the regular electrician, for it does not need to involve specialists. Disadvantages:- large installed capacity of 2. Liquid heating. Advantages: - large heat dissipation due to the wide diameter pipes; - easy to make a system with a large capacity. Cons: - need a continuous source of heat. Sometimes you need to install additional boiler; - additional hardware required for the premises; - to discharge shut-off valve and installation fittings need a lot of time; - if the installation of pipes is performed over a large area, the floor of the lawn may be damaged; - the possible leak harmful liquids.
