Distribution of size in multi-evaporator air conditioning systems

Abstract

SUMMARY This paper reports the thermodynamic optimization of air conditioning systems with one or more evaporators, for one or more rooms. First, the paper shows that the minimization of the total power requirement leads to the same results as the minimization of entropy generation in the whole system, which includes the insulation between the cold space and the ambient. The results also show that there is a trade‐off between the power lost by fluid friction in the distribution network and the power required by the refrigerant. This trade‐off determines the optimal allocation of hardware in the installation. The optimum diameters of the refrigerant pipelines are independent of their lengths.

Tinjauan Variabel Refrigerant Volume

“…Sepanjang proses optimalisasi, respons suhu udara konsisten. Saluran pendinginan yang lebih panjang menyebabkan penurunan tekanan yang dapat memengaruhi kinerja sistem, Pan et al [16] meneliti tata letak satu evaporator di teliti dan dievaluasi, menjaga keseragaman panjang saluran pendingin. Tidak seperti ukuran evaporator, diameter pipa yang ditandai dipertimbangkan dan memberikan kinerja terbaik.…”

Current trends in constructal law and evolutionary design

“…More fundamentally, the field of thermodynamics benefited lately from advances made possible by the constructal law. In air conditioning, multi‐evaporator systems with a network of distribution pipelines can be designed by balancing the power lost in the refrigeration plant and the power dissipated in the distribution lines . Evaporator architectures were also considered in Sabau, Nejad, Klett, Bejan, and Ekici .…”
