Effect of disinhibition caused by humor as an unblocking of creativity in design
Asociación Española de Dirección e Ingeniería de Proyectos (AEIPRO) (2023-07-10)IFixation in the conceptual design process is a problem that affects both creative thinking and the actions taken in the different stages of design. This problem negatively affects new concepts and can lead to undesired ... -
Effects of introducing a parametric Cad in a first year course in engineering degree regarding quality of technical drawings
International Academy of Technology, Education and Development (IATED) (2019-11-11)The evolution of teaching in technical drawing during the last years has been addressed towards new paradigms based on 3D modeling. Nevertheless, not only 3D modeling skills are important for an engineer, but the ability ... -
Energy of the rehabilitation of the thermal envelope of existing building
Universitat Jaume I (2012-07-16)Residential buildings are great producers of CO2 while the current energy context is trying to minimize these emissions into the atmosphere. In order to achieve the requirements imposed by legislation, we must improve ... -
Evaluation of zerotropic mixtures as refrigerants in a dedicated subcooling system of a CO2 refrigeration plant
Universidad Politécnica de Cartagena (2022)Prof. Baomin Dai suggested in 2018 that the use of zeotropic mixtures with high glide could provide energy improvements as refrigerants in dedicated mechanical subcooling systems for CO2 plants due to matching of temperature ... -
Experimental Assessment of the Internal Heat Exchanger in Vapour Compression Systems With Low GWP Refrigerant R516A
Elsevier (2022)Internal heat exchangers (IHX) are commonly used to improve the energy performance of vapour compression refrigeration cycles. However, the magnitude of the improvement depends on the refrigerant and operational ... -
Experimental drop-in comparison of R516A for water-to-water refrigeration applications
Universidad Politécnica de Cartagena. Ediciones UPCT (2022-04-17)R134a is still one of the most used hydrofluorocarbons (HFCs) in refrigeration and air conditioning applications. However, it should be phased out in the coming years because of its high global warming potential (GWP). The ... -
Experimental evaluation of alternative CO2-based blends for transcritical refrigeration systems
International Institute of Refrigeration (IIR) (2023-08-21)This work presents two refrigerant CO2 blends with R32 and R1270 designed with a theoretically nonflammability and a GWP below 150. Both mixtures were tested in a small-capacity vapour compression system with and without ... -
Experimental evaluation of different refrigeration system configurations using CO2-based blends as refrigerants
International Institute of Refrigeration (IIR) (2023-08)Recently, blends created by mixing CO2 with another fluid with a higher critical temperature are being considered, to allow subcritical operation at high outdoor temperature, thus increasing the COP. The goal of this ... -
Experimental evaluation of the azeotropic mixture R516A as an R134A drop-in alternative for moderately high-temperature heat pumps
Universidad Politécnica de Cartagena. Ediciones UPCT (2022-04-17)The moderately high-temperature heat pump (MHTHP) is a market with a great potential to reduce greenhouse gas emissions from the heating sector. However, future proof MHTHPs cannot be based on hydrofluorocarbons with high ... -
