Odnim iz vozmoznych istocnikov nizkopotencial’noj teploty dla sistem teplosnabzenia mogut byt’ stocnye vody sistem kanalizacii. V stat’e vypolnen obzor i sravnenie suscestvuuscich ustrojstw i sistem dla utilizacii teploty stocnych vod vo vnutrennich i naruznych sistemach kanalizacii, v castnosti predstavleny preimuscestva i nedostatki ispol’zovania ustrojstv i sistem.

One possible source of low-grade heat for heating systems is sewerage waste water. The article presents the review and the comparison of existing devices and systems for heat recovery of waste water in the interior and exterior sewer systems, in particular, the advantages and disadvantages of the use of devices and systems.

Regression comparison of organic working mediums for low grade heat recovery operating on Rankine cycle

Shahinfard S., Beyene A.

Journal of Power Technologies

2013

Vol. 93, nr 4

257--270

A logistic-regression based classifier is developed here to predict the probability of any working fluid as a desirable candidate for ultra-low grade heat driven organic Rankine cycle. Global warming abilities, ozone depleting potentials as well as thermodynamic properties of the working medium are used to develop this generalized classifier. As a validation of the suggested classifier, more than 80 working fluids are screened, and regression analyses used to rate the most appropriate candidates. The preferable working mediums among those evaluated based on environmental impacts are HFCs. Considering environmental issues, safety concerns, and performance characteristics however, the preferable working fluids among those tested are HFC-245fa, followed by HFC-134a, HFC-227ea, HFC-236ea, HFC-236fa, HC-600, HC-600a, HC-601, and HC-601a.
