Weswen company presentation

  1. 1. Clean technology everybody
  2. 2. About WESWEN companyThe development of alternative energy forms and the search of alternative energy sources are the mainworldwide trends of the new millennium. The reasons underlying these processes are the exhaustibility ofhydrocarbon resources and the prospect of energy crisis in the near future; negative environmental impactand the threat of the world ecological catastrophe; the necessity of lowering power inputs to reach greaterproduction efficiency.WESWEN company develops and introduces modern technologies ofusing alternative sources of energy – solar, wind, water and geothermalenergy.We offer a series of effective systems of converting inexhaustible andrenewable natural energy: solar batteries and collectors, wind-poweredgenerators, thermal pumps and wave power plants. They can be used inthe regions located far from the centralized systems of heat and energysupply, in the regions with capacity shortage, and for the supply ofhouses, enterprises, and other facilities. The use of these devices ensuresuninterrupted power supply.Our systems are ecofriendly and absolutely safe for users and theenvironment.
  3. 3. About WESWEN companyQuality: Strategic targets:• Use of high-grade materials and • High-quality production products • Improvement of systems of• Product inspection alternative energy conversion• Operation improvement • Expansion of the sector of• Personnel training, constant growth procurement and engineering of the employees’ professional level solutions• Implementation of the quality • Cost reduction owing to effective management system production and expenditure reduction • Environmental protection Our mission is to create a modern safe and convenient communication environment between the Man and the Nature.
  4. 4. WESWEN solar batteries and collectorsRange of application: • Mobile consumers of heat and energy supply (mobile hospitals, mobile search-• One-family detached houses and-rescue teams, scientific expeditions, troop units in the field,• Office blocks and buildings, frontier posts, gamekeepers’ posts in educational institutions, sports the wildlife reserved areas, etc.) facilities • Transport• Manufacturing facilities• Agricultural sector• Sparsely populated residential areas
  5. 5. WESWEN solar batteries and collectorsPrinciple of solar battery operationTransformation of electromagnetic wave (light) energyinto electric energy.Light flux hits the surface of a solar battery andtransforms in the battery material into electricity.The electricity generated by the solar battery goes to thestorage battery charges under controller control andaccumulates there.From the storage batteries electric energy goes to theinverter, transforms there into alternating current of anappropriate voltage level, and then goes to the finalconsumer.
  6. 6. WESWEN solar batteries and collectorsPrinciple of solar collector operationTransformation of solar radiation energy intothermal energy.A solar collector is a set of blacked tubes connectedat the top with a heat-exchange tank.In the tubes the liquid gets warm from solarradiation and begins to boil. Then, steam goes up tothe heat-exchange tank, and transfers heat to waterthat can be used in the heating system or in the hotwater supply system.
  7. 7. WESWEN solar batteries and collectorsAdvantages: Drawbacks:• General availability and inexhaustibility of the • Dependence on illumination and daylight hours energy source • Small efficiency degradation in the course of• Long life time • Moderately high initial costs (for a battery)• Safe for the environment• Reliability• Ease of maintenance and operation• Moderate price (for a collector)
  8. 8. WESWEN solar batteries and collectorsCost efficiency:Cost efficiency of solar batteries is determined by a number of factors:climatic conditions of the area where solar modules are installed, electricityconsumption mode, local power rates, cost of solar modules, etc.If we consider a solar module (1 kW power) located in the zone ofmoderate solar radiation intensity on the Ukrainian territory, in view of thefact that electricity consumption is spent on the auxiliaries, we canconfidently say that the payback period will be less than 15 years.If solar modules with greater power are used and the generated energy ispartially distributed to the shared electrical network, the payback periodcomes down to 8-10 years.
  9. 9. WESWEN wind-powered generatorsRange of application:• Agriculture • Power supply of automated control systems,• Manufacturing facilities communication and supervisory• Cottages control facilities, medical• Small farm enterprises apparatus, computing• Small villages machinery and other• Transport (yachts, small size equipment, critical to the vessels) quality of electricity
  10. 10. WESWEN wind-powered generatorsPrinciple of wind-powered generator operation• Transformation of wind energy into electric energy.• A wind stream runs against wind turbine blades and makes them turn. Wind turbine blades are mechanically connected to the generator rotor, which also starts to revolve.• As a result of rotor rotation, generation of electricity starts in the generator. Under controller control the electricity goes to the storage battery charges and accumulates there.• From the storage batteries electric energy goes to the inverter, transforms there into alternating current of an appropriate voltage level, and then goes to the final consumer.
  11. 11. WESWEN wind-powered generatorsAdvantages: Drawbacks:• General availability and inexhaustibility of the • Dependence on wind force energy source • Needs to be installed at the height (on the• Long life support) • Noisiness• Safe for the environment • Moderately high initial costs• Reliability• Ease of maintenance and operation
  12. 12. WESWEN wind-powered generatorsCost efficiency:Payback periods and appropriateness of the wind-poweredgenerator installation depend on several factors: wind force atthe installation site, proximity to the electrical supply network,availability of the installation place for the wind-poweredgenerator.Initial rotating velocity of the wind-powered generator is 2m/sec. The speed at which the generator operates with onehundred percent efficiency is 8-10 m/sec. Naturally, the higherwind velocity is, the more effectively the generator operates.But it doesn’t mean that it is unprofitable to install a wind-powered generator if wind velocities are lower than optimalones. Our experts will help find the right place, and the mosteffective model and packaging arrangement of the wind-powered generator.The payback period for the wind-powered generators is about 5-7 years. If there is no electrical supply network or there arecyclic power cutoffs, the payback period will be about 3-5 years.
  13. 13. WESWEN thermal pumpsRange of application:• One-family and multifamily houses• Industrial projects• Workrooms• Office blocks and buildings• Public buildings: nursery and daycare facilities, educational institutions, health facilities, cultural and educational institutions, shopping and entertainment centers, etc.
  14. 14. WESWEN thermal pumpsPrinciple of thermal pump operationThe principle of thermal pump operation is based on thecollection of heat from ground or water, and its transfer tothe heating system of the buildingPassing through the compressor the coolant compressesand heats up to a high temperature, and then moves to theheating system of the building. On leaving the heatingsystem, the coolant cools down in the expansion valve tolow temperatures and moves to the heat exchanger,situated in the ground or basin. In the heat exchanger thecoolant heats up by the ground or basin heat, and thenmoves to the compressor. The cycle repeats again.If the building needs cooling (conditioning), the oppositeprocess takes place: heat is taken from the building andmoved to the ground or basin.The same thermal pump can operate in heating mode inwinter, and in cooling mode in summer.
  15. 15. WESWEN thermal pumpsAdvantages: Недостатки:• Doesn’t need fuel • Well-drilling in the ground for• No irritants thermal pump placements • Needs power supply• Long life • Difficult in operation and• Versatility (heating and conditioning) maintenance• Effectiveness • Moderately high initial costs• High efficiency
  16. 16. WESWEN thermal pumpsCost efficiency• Cost efficiency of thermal pump use depends on• the temperature of the low-potential thermal energy source;• the cost of electricity in the area;• the prime cost of thermal energy, produced using different kinds of fuel.• The use of thermal pumps instead of traditionally used sources of thermal energy is economically sound because of:• no need to buy, transport and store fuel;• the freeing of a considerable territory, necessary to place a boiler room, driveways and a fuel storehouse.• Initial costs of thermal pump installation are a little higher than the cost of standard heating and conditioning systems. The cost of the pump and the system installation is $300–1200 per 1 kW of the needed heating power. The payback period of thermal pumps is 4-9 years with the life time until general overhaul of about 15-20 years. However, if to consider maintenance costs, then the initial investments in geothermal heating, cooling and hot- water supply are quickly repaid because of the energy saving. Besides, it is necessary to consider that a thermal pump, when operated, doesn’t need any extra communications, except for home electric network.
  17. 17. WESWEN wave power plants Range of application:• Power supply of the facilities situated in the coastal zone• Power supply of the offshore facilities (drilling platforms, vessel roads, beacons)• Power supply of small islands• Power supply of coastal cities
  18. 18. WESWEN wave power plantsPrinciple of wave power plant operationTransformation of wave energy into electric energy.In the power plants of the first type the transformation of kineticwave energy and energy of surface oscillations into electricity takesplace.Kinetic energy of the wave coming into the tube rotates the turbineblades which set the generator in motion. In the other case thecoming water pushes the air out of the closed space of the tube.After that the generation of energy goes as usual. The escaping airrotates the turbine blades of the generator.In the power plants of the second type, when the energy of waverolling is used, electric energy is generated by the floats on thewater surface. Rocking them, waves set in motion the float-generator system, which results in energy generation
  19. 19. WESWEN wave power plantsAdvantages:• Doesn’t need fuel• No irritants• Long life• High specific powerDrawbacks:• Dependence on wave force• Difficult in operation and maintenance• High initial costs
  20. 20. WESWEN wave power plantsCost efficiency:Wave power plants have a number of advantages:• high efficiency (up to 70%), determined by the fact that the power plant is a flexible energy-absorbing system that continuously changes its parameters under the influence of incoming sea waves with wide-ranged lengths and amplitudes• the level of specific capital costs ($3,500-4,000 for a kW)• low cost of the generated energy ($0,05-0,08 for 1 kW/h)• low materials consumption (less than 150kg/kW)• high resistance at stormy sea• mobility (can be towed off to any part of the water area)• payback period of water power plants is 2-5 years
