The standard solution when a problem providing backup power of any object is a diesel power plant. What do you do if the on-site diesel power plant is not possible? There is no playground, no place to install, etc. There is a solution – is to install backup power inverter system. In this system, two main components. The first is the inverter, the second is a set batteries.
Inverter or converter in other words, provides consumers with power, which vyrabatavetsya due to the energy of batteries (battery). on the issue. The composition may include an inverter automatic switch between AC mode and on battery. In this switch to on-battery failure occurs when the main power supply. Moreover such a device may contain embedded charger which monitors the battery and with an external power supply provides a battery charge. Inverter systems are autonomous and operate in automatic mode. Periodic intervals service can be quite lengthy. Advantages of the inverter system of 5-10kW in the room before installing a diesel power plant of the same capacity with a 5-10kW and heating system, automatic engine: less installation cost, no need to work on the organization of general ventilation and exhaust systems lack the cost of sound insulation (noise level of the two fans inverters) absence need to switch inputs AVRE cost about 1000u.e., inverter system includes a static switch that performs this funktsiyunet need for periodic testing zapuskovotsutstvuet periodic inverter system maintenance (oil changes, filters, fuel refilling) periodic maintenance inverter system power consumption of cheaper own inverter system is comparable to the power consumption of the system generatoramenshaya heating area in the room for the inverter sistemyvlozhenie funds in the battery is commensurate with the cost of servicing the generator: the replacement of coolant, oil, diesel toplivo.Invertornaya system allows the use of additional energy sources: wind generator and or photovoltaic modules. At the same time, the combined system using the inverter system stand-alone power and can achieve fuel economy and engine life of the generator due to the parallel load-sharing, including compensation for power peaks.
These requirements kilns include requirements for aerodynamics: The kilns should be provided with a uniform velocity of air circulation in the material. The speed depends on the species and thickness dried boards. For the thin planks of wood fast drying rocks efficient high-speed air flow (2.0-2.5 m / s). For thick boards, and drying is particularly difficult to breed, the speed may be reduced in two times without performance degradation kilns (the same quality at the same time will be higher than at a high rate of circulation). Thus, the efficient conduct of the drying process must be able to controlling the speed of air circulation, at least 2 speed motor. Perhaps check out Artis Stevens for more information. Note that low speed is required when drying fast drying wood (drying from 18 to 20% and final moisture content).
If the kilns are not provides regulation of air, to manage this process by using gaskets. However, this will inevitably lead to poor performance by 10-15%. Requirements for fencing: – Fences should be tight. – Have a strong internal moisture barrier. – Have the best thermal protection for the heat transfer coefficient of 0.3-0.4 W/m2 at least 0C.
This requirement stems from not only saves heat energy but also the need to maintain the drying mode. Requirements for thermal equipment: – drying chamber should have sufficient thermal capacity, providing lift and maintain the temperature at a given level. – Heaters should be made of stainless steel materials. Requirements for ventilation of chambers: – Ventilation chamber should provide a stable supply air parameters in both summer and winter (air should flow into the chamber, having a positive temperature). This is achieved through the use of cameras in the recovery systems, air parameters – energy recovery. When using the camera without energy recovery in the winter time, productivity is reduced by 20-40%. The reason – incoming cold air is not only condenses the moisture (that is the reason for the increase of drying time in the first stage), but also negatively affects the quality of the drying process. If the use of recuperators for some reason impossible, to organize the chamber forced exhaust the exhaust air, and to organize the inflow from the premises. Requirements for monitoring and controlling the process: – Cameras need to be provided psychrometric system climate control. It should be noted that the system shows the worst results UGL – control of temperature and equilibrium moisture content of wood, which are equipped with many imported dryers. Research have shown that the adequacy of indications of this system is worse than a psychrometric. This means that violate the drying and, consequently, affects the quality of dried lumber. – The cameras must be equipped with control system of the current moisture content of wood as a common division of the drying process with respect to time gives the worst results. – Managing the process should be automatic. In Finally, we note that the Department of Technology woodworking industries have much experience of reconstruction and development projects of new kilns, the examination of imported equipment, improve technology and organization of the drying plants, which can be very useful for producers.
Comprehensive automation of production – is labor intensive work that requires large expenditures. When you automate most of the production processes take place under human control, but without his participation, which leads to increase productivity, reduce the number of workers and reduce energy costs. A typical level of automation is the control system (automation systems and industrial processes). Most often, PCS used in the oil and gas industry, but has recently been actively used in housing and communal sector and industry. Physicians Committee for Responsible Medicine recognizes the significance of this. The main advantage of the introduction of PCS in Housing is: an increase in service life of equipment by 1.5-2 times, reducing the number of accidents at the facilities, the management in the automatic mode on a fixed schedule, minimizing the role of the "human factor". The introduction of PCS at the production saves raw materials and supplies, improve the quality of their products.
The main functions of the control system are: 1. Processing, storage, and storage information. 2. Visualization of technological processes in real time. 3. Graphing, reporting, building alarms, etc. 4.
The control and management. In the engineering department company "Elcom" daily developed automated control system, from simple to multi-tiered, with its own software products. The payback period is determined by the automation by many factors and depends on the type of process. On average, self-sustaining process control system comes in 1-2 years. An important part of automation is the inverter. Now no production can not do without this type of equipment. Frequency converters are used in industries such as heating, water, and, more specifically, in the pumping plants, exhaust, etc.
And accordingly, the same increase in fuel costs. Think for yourself. Heating a private home: pipes Finally, you will need to decide on how the pipes in the heating devices will be supplied water. Widely used in the past steel pipes today are not used, because installation of time-consuming, but life is not so great (due to corrosion). In addition, repair or relining of steel pipe – not an easy task.
Also, experts do not recommend use in heating private houses so Viewed today composite tubes. The fact that they sometimes have a tendency to burst at the bends, while under the influence not so much pressure as the temperature. Therefore the choice of the best stop on a copper or a polymer (eg, made of reinforced polypropylene and cross-linked polyethylene) pipe. Copper the most durable and resistant to external influences and convenient for maintenance, but using it requires considerable financial costs. So in most cases the best choice for heating private houses will be polymer tube.
Of course, we have examined here, not all questions connected with the organization of the heating of private homes. However, the main covered his attention and the most common issues on which attention should be paid to the owner. Defining priorities for yourself, everything else you can solve by using the help of professionals. C housewarming! Heating of a private house: The price issue, but at what cost the same amount of heating of private homes? The answer to this question is not so easy, because a lot depends on your house, its layout and the existing needs. Experts call very different prices – an average of 1,000 to 2,000 rubles per square meter of heated area. You also need to understand that the more the house, the less will end up in terms of "square", because the changes only the length of piping and number of radiators, the boiler and the cost increases is not proportional to its capacity. For example, if you have a one-story cottage with a total area of 100 square meters, it is a reasonable approach, but without excessive economy, the heating system with gas boiler will cost about 150-200 rubles. While on a two-storey house of 300 m2 will take about 300-350 thousand. Specialists of "Ekokomfort" recommend to look beyond price equipment and installation, and on home heating costs in the long run. That is, the actual cost of the system to add the cost of its maintenance and fuel, say, over the next 20 years. And, dividing the resulting figure by 20 to estimate how much you will be heating annually. For example, as a result of this calculation turns out that the gas boiler ototpleniya, even with the cost of individual connection to the backbone, "eat" about 27 thousand rubles a year, while Oil and Electric – approximately 135 000.
