Abstract

Cooling circuits can be improved by using a desuperheater. A series connected desuperheater increases the efficiency of the circuit and allows the waste heat to be used, e.g., for DHW preparation. The study investigates the behavior of a parallel connected desuperheater for DHW preparation in an experimental cooling circuit. The basic parameters of the cooling circuit (efficiency, pressure, temperature and energy consumption) were evaluated when operating 1. with only a condenser and 2. with a condenser and a desuperheater connected in parallel. The results of the study show that a parallel connected condenser and desuperheater reduces the overall efficiency of the cooling circuit.

并联减温器在冷却回路中的效率

冷却回路可以通过使用减温器来改进。串联的减温器提高了电路的效率，并允许使用废热，例如用于DHW制备。在实验冷却回路中，研究了用于制备DHW的并联减温器的性能。在运行1时，对冷却回路的基本参数(效率、压力、温度和能耗)进行了评估。只有一个冷凝器和2。冷凝器和减温器并联连接。研究结果表明，并联冷凝器和减温器降低了冷却回路的整体效率。
