Cycle Characteristics of a New High-Temperature Heat Pump Based on Absorption–Compression Revolution

چکیده
A large amount of the waste heat generated during industrial production is not used, which leads to a low energy utilization rate. The recovery using pumps has advantages consumption, high efficiency, safety, and environmental protection. Industrial wide temperature distribution range. Traditional absorption compression can only work in narrow range due thermodynamic cycle, thermal properties working medium, pressure resistance compressor, other factors; they cannot simultaneously meet requirements “high heating temperature” “wide temperature-range transfer”. To solve above problems, this paper proposes high-temperature pump unit based on coupled cycle compression, recover low-temperature steam 50 °C produce hot water at 110–130 °C. EES software used for mathematical modeling simulation analysis unit. results show that, when driving 140 °C, reach 110~130 COP system 4.22. Increasing outlet condensation strengthens cycle; meanwhile, increasing evaporation reduces cycle. study significantly broaden operating electric pumps; our findings therefore have essential research significance improving efficiency fields.

four kinds of refrigerant mixtures R22/Rl34a, R22/Rl52a, R22/Rl42b and R22/Rl23, which contain some new halocarbons which are considered to be the alternatives for CFCs, were evaluated in order to realize higher condensing temperature than that using R22 at high temperature operation, and larger heating capacity than that using R22/Rll4 at normal temperature operation. These mixtures were appli...
