Description
В зоне расслоени температура кипени при посто нном давлении не зависит от состава смеси. Если кипение провод т при давлении обратного потока 0,12 МПа, то ДРС обеспечивает температуру 150°К в диапазоне мольных концентраций Р 14 от 5 до 95%. Вар ирование давлени обратного потока позвол ет получить любую из температур охлаждени 140 - .In the zone of stratification, the boiling point at constant pressure does not depend on the composition of the mixture. If boiling is carried out at a reflux pressure of 0.12 MPa, the DSU provides a temperature of 150 ° K in the range of molar concentrations of P 14 from 5 to 95%. Varying the reflux pressure yields any of the cooling temperatures of 140 -.
Из таблицы видно, что предложенна рабоча .смесь при таком же низком давлении пр мого потока, как и у известной смеси, обеспечивает холодо- производительность на 52% выше. Кроме этого, смесь Р 14-пропан обеспечивает увеличение эксергетическогоThe table shows that the proposed working mixture with the same low pressure of the direct flow, as in the known mixture, provides cooling capacity by 52% higher. In addition, a mixture of P 14-propane provides an increase in exergic
КПД на 18%. Это объ сн етс тем, что у пропана величина интегрального изотермического дроссель-эффекта при одних и тех же перепадах давт лений и начальной температуре выше, чем у Р 22 Кроме того, холодопроизводительность смеси Р 14-пропан составл ет 1,25 Вт, в то врем как дл смеси Р 14-р 22 она составл ет только 0,82 Вт.18% efficiency. This is due to the fact that propane has an integral isothermal throttle effect at the same pressure drops and initial temperature higher than that of P 22. In addition, the cooling capacity of the mixture P 14-propane is 1.25 W, while while for a mixture of P 14-p 22 it is only 0.82 watts.
Таким образом экономическа эффективность при применении смеси Р 14-пропан заключаетс в повышении холодопроизводительности и эксергетического КПД без применени конструкции дроссельного микротеплообменника .Thus, the economic efficiency with the use of a mixture of P 14-propane consists in increasing the cooling capacity and exergy efficiency without using the design of a throttle micro heat exchanger.
