“…Outdoor condensing boiler is known, equipped with hydro-thermally insulated casing. The invention increases the efficiency of the boiler during a power outage, but has drawbacks -the impossibility to use the boiler for industrial purposes, as well as the high specific cost of heat generation [15][16][17]. Wall condensing boiler Logomax plus GB172i is known.…”

The purpose of the work is the development of environmentally friendly technology of heat recovery from condensation of water vapor at a constant partial pressure of the outgoing flue gases in contact heat exchangers with a passive nozzle at thermal power plants running on natural gas, and the use of solar heaters in the block structure of an absorption refrigerating machine. Using contact heat exchangers can reduce greenhouse gas emissions. Greenhouse gas is harmful to the environment. Using solar heaters can improve the efficiency of the Li-Br absorption refrigerating machine. Ways to improve the efficiency of industrial enterprises are different. One of the main ways is to use renewable energy for heat recovery. In addition, the use of renewable energy sources reduces emissions of harmful greenhouse gases into the atmosphere.

“…The power range of these devices ranges from 7 to 200-250kW. Evaporator pressure loss depends on the diameter of the evaporator tubes, fan configuration, airflow rate and the amount of condensate leaving [9,10]. At the moment, seawater desalination schemes are on an industrial scale in countries with a hot climate and in the absence of fresh water sources.…”

The article considers the processes of modeling the flow of a refrigerant and presents the results of numerical simulation of freon evaporation in a tubular evaporator. The results show the effect of convective heat transfer and bubble formation on the heat transfer coefficient. It is assumed that this technology can be used, among other things, as an element for water desalination. The possibility of using heat pumps and the organic Rankine cycle in the scheme of water desalination is considered. The authors propose to design such energy-technological complexes, starting from the stage of numerical simulation. The modeling results and the developed schemes presented to the attention of readers are part of a unified methodology for heat pumps and desalination systems.

“…Based on the three-parameter CSP, a model is proposed for estimating the isobaric heat capacity of biodiesel-related esters in the liquid state [2]. A new corresponding-states (CS) model for estimating the vaporization heat of working fluids used in organic Rankine cycle is proposed [3]. A CS group contribution method is proposed to estimate surface tension of ionic liquids [4].…”

The law of corresponding states (LCS), based on a generalized van der Waals equation of state (gvdWEoS) has been formulated by rescaling its thermodynamic variables with liquid - vapour critical – point parameters, the spinodal, the thermodynamic limit of superheat (TLS) and the supercritical (SC) point. This gvdWEoS, which satisfactorily describes the properties of alkali metals, differs from the known van der Waals equation of state (vdWEoS) by the modified attractive term. The scaling properties have been derived on the basis of the gvdWEoS. The expressions for the isothermal compressibility, a derivate of Gibbs free energy have been derived. In all these cases of rescaling, the gvdWEoS has the similar functional form and the expression for isothermal compressibility has a similar functional form. Hence, it has been established that the parameters of at any spinodal-point on the phase diagram, including the TLS as a particular case, and the SC point, characteristic point on the quasispinodal, provide the alternate scales of parameterizing the fluid properties other than the liquid-vapour critical point.
