Objective
The aim of the research is to build up a European method for calculation of annual efficiency of domestic boilers. Compared to the existing methods, the proposed method will allow a fair comparison calculation of the annual efficiency of boilers by taking into account the dynamic behaviour of the equipment. The method will also take into account the installation characteristics and the climatic conditions. Based on measurements available (CEN standard), the method will, on the basis of the mandatory unique test of CEN, allow predictions of the annual efficiency in different countries and for different installation configurations.
This method will provide consumers, energy planners, etc., with a tool for choosing the boiler best fitted for the existing (or under construction) installation. The method can also be used for labelling the boiler for different standard conditions. A common generally accepted method will bring attention to the energy efficiency of the entire system : boiler, building, heat distribution system, and components. Due to the number of boilers installed in the EC every year (about 3.700.000 in 1992), the economic impact of the method would be substantial. The yearly consumption of an installation could be estimated between 5 and 50 MWh. The project proposers are also in a good position to spread the use of the method and make it accepted by the partners (manufacturers - standardization organisations).
Compared to existing national methods, this method will take the dynamic behaviour of the boiler in real conditions into account.
The model will be integrated in a simple environment (building and heat distribution system model, climatic conditions).
The method will be developed so that it can be used as a standard. This means that it must be transparent and should not necessarily need the use of a computer to be applied (e.g. no iterative calculation, etc.).
A practical tool for consumers, etc., will, nevertheless, be developed in a computer program capable of reading a boiler data base (which includes characteristics required to calculate the annual efficiency) and a climatic data base.
No additional measurements on boilers or on heating installations are required when using the method based on the available data (CAN standard). Nevertheless, additional measurements on boilers would improve the accuracy of the final result.
The following parameters will be taken into account in the method :
1. Boiler characteristics (efficiency, full and part load, stand-by losses, start/stop losses, etc.).
2. Installation characteristics (building size and insulation, control system, heat distribution system).
3. Consumer (indoor temperature, hot water demand, etc.).
4. Climatic conditions.
The method developed will be used to develop, at least, the following applications.
1. Generally acknowledged method for choosing the most suitable boiler for a given installation.
The method is to be used by
- consumers
- energy planners
- advisors
- etc.
2. Practical use of the method for a restricted number of standard installations (could be used as a kind of labelling system).
