The amount of volume coefficient depends on elevation of location of gas consumption and the temperature of gas flowing through the gasometer. In this paper we describe the procedure by which you can check that the coefficient of volume on the invoice is correct. The coefficient is one of the factors that affect your cost of gas.
The paper deals with basic separation of fuels and their classification on the basis of various points of view. There are mentioned descriptions of basic characteristics of fuels which are usually determined for standard fuels. Lastly, there are mentioned general parameters of the most widespread fuels and short description of incineration.
The article deals with the introduction of underground heat exchanger for preheating and precooling air for buildings. The introduction is devoted to the description of the system and its individual components and parameters that influence the behavior and performance of the system most. The second part presents a simple model, where you can see how each change affects the actual parameters of heat and cold, which can be gotten from the system.
Regular inspection is focused on boilers and smoke flue, its accessories, security and regulation. The article presents an example of inspection of the thermal system with older atmospheric gas boiler in a house without insulation. Technical details of the revision are completed with final report as a result of the inspection .
The use of GE depends on the predisposition source, namely geothermal boreholes. The use itself is different when using the heat for heating, hot water, heating greenhouses and plastic greenhouses (agricultural), recreation facilities, but also for various technologies. The inclusion of monitoring and control system for an open geothermal energy system is achieved by taking friendly geothermal water and substantially increases the life of the whole work.
The author in his article deals with intermittent heating of buildings, specifically optimizing the operation of the heating system so that the change in the heating mode - in compliance with the required quality of the indoor environment during the heating breaks - achieved economic savings due to reduced output of the heating system design.
Supply of gas or electricity is so important that many customers do not want to risk a possible interruption when changing suppliers. New legislative rules defined in an amendment to the Energy Act No. 458/2000 Coll. (as amended by Act No. 211/2011 Coll.) but fill existing gaps in legislation and establish a procedure for changing supplier.
The article describes the methodology of experimental verifying of the performance of heat pump in real conditions. Namely the air-water type of heat pump was evaluated. Heat pump has been observed in extreme climatic conditions and the resulting measured and calculated parameters were compared with the parameters specified by its manufacturer.
The aim of the authors is to evaluate the economic effectiveness of choosing of the heating system for family passive houses and to compare it with the same systems used in common buildings. Methodology of the comparison consist in real market offers and price lists in price level of first half-year 2011. The work is based on the case study of simulated passive house. The result encompasses confrontation of the overall costs of energy supply for family house for 15 years. At the end of the article the overall benefits of passive houses building and management are discussed.
Regular inspection is focused to the boiler, smoke flue and accessories condition, its security and regulation. In addition to the technical condition and maintenance, the documentation, operating instructions, manuals and other documents are under inspection. It quantifies the overall boiler efficiency of measurement results, sets reference respectively minimum boiler efficiency and suggests possible actions.
Oil is the energy source No. 1, and the world is in a period of peak oil. Serious paralysis of economy after peak oil is almost certain, because economic growth demanded increasing consumption of fossil fuels from the beginning of the industrial revolution.
The Czech Republic can ensure its energy security only in integrating with Europe, and especially the connection to Europe's energy (especially electricity and gas) and transport networks and participation in the transformation of post-fossil energy and transport system.
Long-term air quality data collected in areas affected by pollution from large industrial sources, reported during the heating season, the remarkable changes that indicate a significant proportion of small sources in impaired air quality. Residents and their boiler is considerable work involved in air pollution.
