Abstract
Heating of small buildings is usually performed by a combustion of liquid fuels, which transformation into heat is due to a highly sophisticated burners efficient. Despite to all that, due to the rise in the fossil fuel prices, the cost for heating of buildings increases each year. Decrease can be reached in many ways, e.g. with change in the way of construction of the buildings or with the use of more efficient heating devices.
To the of absorption devices it is specific, that in special cases, where heat for evaporator is transferred from the surrounding air or other low-temperature source, they can produce more heat on the unit of driving energy of primary sources than the classical devices. Therefore their use for the heating of buildings is from the thermodynamic point of view very reasonable. Still due to the momentary high prices these devices are not market interesting.
Therefore a study is required, which would give us as a result a design of absorption devices, which would be thermodynamically and economically the most suitable for the heating, and optionally cooling of the small buildings. A review of possible and practically feasible absorption devices will be performed. The internal processes in the devices will be numerically simulated, which gives us the possibility to observe the operation of the device for the change in the boundary conditions, e.g. the temperature levels of heat sources and sinks. In the simulation process, the square-root criterion will be used also. Its function is to include the economic parameters to the process of the devices selection also. The result will be the range of the economically most suitable absorption devices, which could be used for heating and in parallel for cooling of different types of the small buildings also. With a parallel usage of heat and cold is the total efficiency of primary energy transformation even higher.
The knowledge, which will be acquired in the frame of this project, will serve to the further development of compact absorption devices for cooling only. In the project a several guidelines for a construction of a small, compact and cheaper absorption devices will be given. This will be performed over the review of the existent literature and with a regard to the knowledge acquired in the project.
