Řešení zdravotechniky rodinného domu v Ostravě - Plesné

Abstract

This bachelor’s thesis deals with the design of sanitary installations for a single-family house located in Ostrava – Plesná. The thesis includes the preparation of project documentation at the level of detail required for construction. The documentation covers both the building design and the building services systems, with a focus on sanitary engineering. The proposed building is a detached single-family house intended for a four-member household with intermittent occupancy. This mode of operation places increased demands on the hygienic safety of the internal water distribution system, particularly with regard to the prevention of water stagnation and deterioration of water quality. The core of the thesis is therefore devoted to the design of the internal water supply system, including a variant solution. A conventional system is assessed alongside a cold water recirculation system (bypass system), which enables water flow even in dead-end branches of the piping network. This solution contributes to reducing water stagnation during periods when the building is not in use and improves the hygienic safety of the system. The design also includes the preparation of domestic hot water using a combination of solar thermal collectors and an air-to-water heat pump, with the aim of increasing energy efficiency and utilizing renewable energy sources. The theoretical part of the thesis addresses the issue of cold water recirculation, its importance in terms of drinking water quality, its operating principle, and possibilities for practical application. It also includes a comparison of the proposed variants in terms of technical design, operation, and suitability for use.
