The article deals with the issues of water consumption in the production of ethyl alcohol from grain raw materials. The data on its demand for technological needs (for preparing a batch), as a refrigerant, for steam generation, for household needs are given. It is shown that water in specific terms is the most voluminous raw material resource (up to 1600 m3/1000 decaliters), but at the same time it is practically not consumed as a reagent for technological purposes. The analysis of options for the reuse of water was carried out and the possibility of reducing its consumption to 200 m3/1000 decaliters was shown, due to the repeated use of cooling water, by introducing a circulating water supply system, constant circulation of water through the cooling towers, where it is cooled. It is also noted the possibility of complete exclusion of water in the cooling processes through the use of "dry" cooling towers. In this case, the circulation of the refrigerant (for example, ethylene glycol) is carried out in a closed cycle. The relevance of using a single water flow for sequential cooling of semi-products is also shown: fermenting and saccharified wort, boiled mass using efficient heat exchangers of a spiral, plate type. An example is given of reducing water consumption for steam generation by reusing "conditionally clean" steam condensate formed in systems of "dull" heating of semi-finished products. An analysis was made of reducing the consumption of water for the preparation of the mixture due to the processing of raw materials in conditions of high concentrations and the reuse of the stillage filtrate. In addition to saving heat and energy resources, this reduces the volumes of formed stillage and industrial effluents. As a result, the costs of their processing and purification are reduced. A list of measures has been proposed that will reduce water consumption by 10 or more times and increase the profitability of alcohol production by 2–2.5%.

“…Díaz de Garayo 19 proposed a sensible heat recovery HVAC system to further reduce the energy consumption gap with vapor compression heat pumps, and it can be combined with photovoltaic panels to further reduce energy consumption. This indicates that thermoelectric technology has broad prospects for application in passive building HVAC systems.Jiang et al 20 proposed a novel, practical, and commercially valuable integrated water-cooling cycle thermoelectric distiller for alcohol distillation. The device utilizes the TEM to evaporate alcohol at the hot end and uses the circulating water cooled at the cold end of the TEM to condense alcohol vapor.…”

Thermoelectric heat pump is a feasible solution for developing refrigerant-free technology, but most studies tend to focus more on cooling capacity. In this paper, a finite element model of the water-source thermoelectric heat pump module is established. By comparing the changes of the coefficient of performance (COPh) of the thermoelectric heat pump module under different pipe diameters(d), currents(I), temperatures(T), and temperature differences(∆T), the main parameters affecting the performance of the thermoelectric heat pump module are explored. Results show that: within the range of 20°C to 45°C, the influence of water temperature on COPh is relatively small under the same temperature difference; the heat output is not affected by the ∆T when I=7.17A, and the ∆T shows different trends in the left and right intervals: under the condition of large ∆T between the hot and cold ends of the module, there is an optimal working current, which increases with the increase of ∆T.Research has shown that I and ∆T are the main parameters affecting module performance. Under extreme operating conditions, using a specific value of current can simultaneously increase heating power and heating performance coefficient.
