Experimental investigation of refrigerant charge minimisation of a small capacity heat pump. Doctoral thesis.
Author(s) : KTH, FERNANDO W. P. D.
Type of monograph: Doctoral thesis
Summary
In this doctoral thesis, methods of refrigerant charge minimisation without reducing the performance of a small capacity (5 kW) heat pump have been investigated. Work has been focused on finding refrigerant charge distribution in different components of the heat pump, on finding out the solubility of refrigerant (propane) with different compressor lubrications oils, on testing different types of compact heat exchangers, on constructing new minichannel heat exchangers and on finding correlations for calculating the heat transfer of minichannel heat exchangers. The results included in this thesis have been presented in four conference papers and five journal papers.
