Abstract

The dissertation deals with energy issues building heating heat pumps. An example of the use of geothermal energy for heating buildings Aula VSB - Technical University of Ostrava. Chapter 3 addresses the issue of geothermal energy uses of geothermal energy and geothermal energy resource allocations. Chapter 4 describes the theoretical knowledge to transfer heat. Heat transfer occurs in three ways conduction, convection and radiation. Heat is always transferred from one of these methods, or their current combinations. Chapter 5 deals with the calculation of heat loss of the building. Heat losses are calculated according to standard EN 12 831. This standard is currently in force and replaces the previous standard CSN 06 0210. Chapter 6 describes the design of underground wells. The proposal consists in determining the proper length of the borehole and the total numbers of wells needed with regard to the power take off from the ground. The following describes the cased borehole and its implementation. Chapter 7 addresses the principle of heat pump, the kind of compression used in heat pumps and method of operation of heat pumps. Chapter 8 distributes heat pump systems on earth - water, water - water, air - water. It also describes the various systems, their advantages and disadvantages. Chapter 9 describes the building Aula the VSB-TU Ostrava, the method of heating heat pumps ground - water, as well as geothermal energy and how the transfer of heat energy. Chapter 10 introduces the control program Procope. The database recorded electrical quantities, non-electric quantities, such as temperature and control commands. Chapter 11 evaluates database of measured data from the Procope. Chapter 12 deals with the economy in the operation of heat pumps. Chapter 13 addresses the optimization of heating operation. The contribution of this dissertation is the ability to perform optimization space heating heat pumps ground - water.
