Investigation of the influence of mass flow rate on phase change material behaviour

Abstract

The paper presents an experimental study of the influence of heat transfer fluid (HTF) mass flow rate on phase change materials (PCM) behaviour. The experimental study was performed on a specially designed test bench. Research object – PCM based thermal energy storage unit which consists of a stainless steel tank with dual circuit tube-fin copper heat exchanger. The tank (storage volume) was filled with phase change material RT82. The experiment was carried out using three different mass flow rates of HTF: high – 0.25 kg/s, medium – 0.125 kg/s, low – 0.05 kg/s. The analysis showed that in the case of high and medium mass flow rates the melting/solidification process highly depends on the temperature of inlet HTF. Influence of mass flow rate is higher in the case of low mass flow rate.

Šilumnešio debito įtakos fazinio virsmo medžiagos veikimui tyrimas


Santrauka


Straipsnyje pateikiamas šilumnešio masės debito įtakos šilumai kaupti naudojamų fazinio virsmo medžiagų (FVM) veikimui eksperimentinis tyrimas. Tyrimas buvo atliekamas specialiai pagamintame testavimo stende. Tiriamasis objektas – FVM šilumos kaupimo įrenginys, sudarytas iš nerūdijančiojo plieno talpyklos ir dviejų kontūrų varinio šilumokaičio (vamzdelių) su varinėmis plokštelėmis. Talpykla užpildyta fazinio virsmo medžiaga RT82. Tyrimas atliekamas keičiant šilumnešio masinį debitą. Pasirinktos trys vertės: didžiausia – 0,25 kg/s, vidutinė – 0,125 kg/s ir mažiausia – 0,05 kg/s. Nustatyta, kad, esant didžiausiam ir vidutiniam debitams, FVM lydymosi / kietėjimo proceso trukmei didžiausią įtaką turi tiekiamojo šilumnešio temperatūra, esant mažiausiam debitui vyksta didesnė debito įtaka proceso trukmei.
