Abstract

This paper presents the energetic and exergetic analysis of a transcritical carbon dioxide based heat pump cycle for heating. Recycled water (tw=25…40 °C) of food production enterprises is taken into account as a source of low potential heat. The theoretical and real CO₂ trans-critical cycles were analysed. Parameters, which characterize cycles from energy and exergy point of view were obtained. The exergy flow diagram (Grassmann diagram) shows that all the components except the internal heat exchanger contribute significantly to the irreversibilities of the system
CO 2作为中温热泵制冷剂的应用
本文介绍了一个跨临界二氧化碳热泵供热循环的能量和用能分析。考虑食品生产企业的循环水(tw=25…40°C)作为低潜热源。对理论和实际CO₂跨临界循环进行了分析。从能量和火用的角度得到了表征循环的参数。火用流图(格拉斯曼图)表明,除内热交换器外,所有部件对系统的不可逆性都有显著贡献
