Drop-in analysis of an internal heat exchanger in a vapour compression system using R1234ze(E) and R450A as alternatives for R134a
Elsevier (2015-10)The IHX (internal heat exchanger) is introduced in some refrigeration systems in order to achieve higher energy performances. Results obtained vary greatly depending on the refrigerant used and working conditions. This ... -
Effects caused by the internal heat exchanger at the low temperature cycle in a cascade refrigeration plant
Elsevier (2016)This work analyses and quantifies the effects caused by the use of an internal heat exchanger (IHX) at the CO2 subcritical cycle in an HFC134a/CO2 cascade refrigeration plant that incorporates a gas-cooler at the exit ... -
Energetic evaluation of an internal heat exchanger in a CO2 transcritical refrigeration plant using experimental data
Elsevier (2011)The performance of an Internal Heat Exchanger (IHX) operating in a CO2 transcritical refrigeration plant is analysed, from an energetic point of view, in this work. The evaluation is based on experimental data by contrasting ... -
Evaluation of CO2-doped blends in single-stage with IHX and parallel compression refrigeration architectures
Elsevier (2023-07)CO2 is the standard for medium to large-sized commercial applications, as it combines security and low environmental impact. However, it requires the use of advanced and complex cycles. Recently, CO2-doping (the addition ... -
Experimental analysis of R1234yf as a drop-in replacement for R134a in a vapor compression system
(2013-05)This paper presents an experimental analysis of a vapor compression system using R1234yf as a drop-in replacement for R134a. In this work, we compare the energy performance of both refrigerants, R134a and R1234yf, in a ... -
Experimental analysis of the internal heat exchanger influence on a vapour compression system performance working with R1234yf as a drop-in replacement for R134a
Elsevier (2013-09-25)This paper presents an experimental analysis of the influence of an internal heat exchanger on the performance of a vapour compression system using R1234yf as a drop-in replacement for R134a. In this work, we compare the ... -
Experimental comparison between R152a and R134a working in a refrigeration facility equipped with a hermetic compressor
Elsevier (2015-07)The EU Regulation 517/2014 has recently been approved in a further attempt to curb the effects of Global Warming. As a consequence, the refrigeration sector is moving towards refrigerants with a low Global Warming Potential ... -
Experimental evaluation of an Internal Heat Exchanger in a CO2 subcritical refrigeration cycle with gas-cooler
Elsevier (2015-04-05)We present the experimental evaluation of an internal heat exchanger or suction-line/liquid-line heat exchanger in a CO2 subcritical refrigeration plant with gas-cooler. The plant, driven by a 1.5kW CO2 semi hermetic ... -
Experimental evaluation of CO2/R-152a mixtures in arefrigeration plant with and without IHX
Elsevier Ltd (2024-03-01)In recent years, CO2-based mixtures have been considered as a way to improve the performance of refrigerating plants using pure CO2 as refrigerant. Combining CO2 with a fluid with higher critical temperature generates a ... -
Performance assessment of an experimental CO2 transcritical refrigeration plant working with a thermoelectric subcooler in combination with an internal heat exchanger
Elsevier (2022-07-19)Regulations in the refrigeration sector are forcing the transition to low global warming potential fluids such as carbon dioxide in order to decrease direct greenhouse gases emissions. Several technologies have arisen over ...
