ANALYSIS OF HOT WATER HEATING IN CHANGING PHASE OF HEAT TRANSFER MEDIUM.

Peter Hrabovsky, Zuzana Kolkova

Abstract

The article deals with an innovative way to transfer heat for hot water. A device operating on this principle is called a heat pipe. This device works on the principle of phase change of the working fluid (heat transfer medium). The very principle of heat transfer is based on the theory of evaporation and condensation of the working fluid (heat transfer fluid). Heat pipes are classified according to the method of operation and location of use. A subdivision of heat pipe in terms of their actual use in the desired temperature range. As with operating temperature range of the heat pipe it is necessary to take into consideration the proposal of the material used for the application to prevent unsuitable side phenomenon (chemical reaction). The various types of heat pipes have different working conditions and different design. In view of thermodynamic phenomena occurring in the heat pipe it is possible to use the device even heat transfer over longer distances. The process of evaporation, the heat source, and subsequent condensation at the place of consumption of heat (Hot water heating), we based on the use of steam technology units currently in use, ensure efficient transfer of heat contained in the vapor phase working fluid (heat transfer fluid). Currently, heat pipes used in cooling processes of the various technologies (nuclear power, space stations).
