Rationalization of water and energy consumption in shower systems of single-family dwelling houses

摘要: Abstract Reduction of costs incurred for supplying water and heating it household purposes is possible by means an application systems recovering heat from drain in combination with flow limiters. Then, not only advantageous financial results can be obtained, but also positive effects the form reduced use fossil fuels, improved air quality, limited consumption. This paper presents a calculation model that allows to assess synergy different variants investment project consisting mounting limiter DWHR unit shower system single-family building. has large potential used as tool facilitating decision-making process both design modernization stage. A simulation test carried out case study involving shows profitability such depends on adopted variant usage parameters. The best performance characterizes or devices. devices becomes most when taking time long. obtained additionally show favorable achieved buildings which total using facilities longest. presented solutions will be, therefore, particularly profitable characterized significant consumption high rotation users.
