Abstract

The goal of this work is to determine the optimum set of parameters by using the Taguchi method in vapour compression heat pump systems. The experimental apparatus consist of an air-to-liquid vapor compression heat pump, a water cooled condenser, a forced air evaporator, an electrical air and water heaters, and various measuring elements and other auxiliary equipments. Refrigerants R22, R407C, and five of their binary mixtures which contain about 0%, 25%, 50%, 75%, and 100% mass fractions of R407C were tested. To determine the effect of the chosen parameters on the system and optimum working conditions, an experimental design method suggested by Genichi Taguchi was used. The most effective parameters are found to be the condenser water mass flow rate for the coefficient of performance and to be condenser water inlet temperature for the exergetic efficiency.

Özet

Bu çalışmanın amacı Taguchi metodu kullanarak buhar sıkıştırmalı ısı pompası sistemlerinin optimum çalışma parametrelerini belirlemektir. Deney sistemi; su soğutmalı kondenser, zorlanmış hava soğutmalı evoparator, hava ve su ısıtıcıları, çeşitli ölçüm cihazları ve yardımcı ekipmanları içeren ısı pompası sisteminden oluşmaktadır. Soğutucu akışkan olarak R22, R407C ve bunların kütlesel olarak beş faklı (0%, 25%, 50%, 75%, 100% R407C ) karışımı kullanılmıştır. Etkin ve optimum çalışma parametrelerini hesaplamak için Genichi Taguchi tarafından önerilen deneysel yöntem kullanılmıştır. Performans katsayısı için en etkin parametre kondenser su debisi, ekserji verimi için en etkin parametre kondenser suyu giriş sıcaklığı olarak bulunmuştur.
