Heat Meters Petersburg In 2004, the decision was made on the application of measures to improve the accounting system and improving water use calculations for cold and hot water and heating in residential buildings and social facilities, the Moskvy.V St. Petersburg, the project was launched in spring 2005 as prescribed by installation of heat meters (heat meters) shall be capable of remote data acquisition. The implementation of this modernization networks is complicated by the need to replace all the engineering component of the object. From installing a new elevator unit for the failure to install heat meters on the existing site to a complete replacement existing pipelines, made of metal pipes with expired service life, which reduces the cost optimization on heat consumption to nulyu.Tak equipment costs (CGT, temperature sensors, flow meters, valves valves and gauges) for installation of heat metering, are the basis of estimated costs for equipment stoimosti.Krome to affect production cost of technical and design documentation that the new injunction is necessary to pass the metering of heat energii.Ustanovka metering equipment for the heat energiiPodbor metering of heat energy produced by the following criteria: Determine the number of heat registers, depending on the existing networks (with hot water (DHW) - 2 energy meter, with no hot water - a heat meter; Source of heat; The diameter of the input of heating the building; The maximum number allowed by heat (Gcal / h); circuit connection system; DHW circuit (if any); Consumption of hot water (if available); Thermal power; Consumption of heating; Inlet temperature; The temperature at the output. According to the conditions made the choice of equipment. In 2004, the decision was made on the application of measures to improve the accounting system and improving water use calculations for cold and hot water thermal energy in residential buildings and social facilities,...

Clean Solar Energy Solar system at once solves a number of everyday issues, providing hot water, heating homes, heating and chilled water in the pool. Pros transition to an alternative system are obvious: less pay for power is removed dependency on fluctuations in energy prices, and the environment is cleaner. Collector around the main character's head link solar system - a collector. With his help is absorption of radiation. Many domestic consumers it is new. and it is important to select the desired type. It is now widely used flat solar and vacuum tube collectors. The first is considered more reliable because resistance to change our climate. Simple plastic models without glazing advantageous to heat the pool with glass models are universal: suitable for hot water, heating, and even for the pool. Principle collector of the following: solar radiation falls on the absorbing plate and heats it. Heat is transferred to the coolant (water or antifreeze), which is heated and +200 C. Then the energy is transferred through a heat exchanger water in the DHW cylinder, there is at +95 C water is up to the moment of use. To comply with safety requirements, to establish a water outlet valve termosmesitelny supporting temperature not above 55 C. The hot water will be at your house day and night, as the water heater keeps the temperature up to four days. Vacuum tube collectors are susceptible to the effects of a flat element, but has a higher and efficiency of stable value during the year. It is convenient to use in suburban homes with permanent residence. To save space, the collector is usually located on the roof if possible - to the south (to Moscow region). The optimum angle to the horizon line 30-45 . For systems that support the heating, this angle is greater:...
