Integrated supermarket refrigeration for very high ambient temperature
(Elsevier, 2018-12-15)
This paper analytically investigates and compares the performance of a proposed ‘all-natural’ NH3/CO2 cascaded booster system to a conventional R404A direct expansion system as well as to an ‘all-CO2’ system with multi-ejector ...
Protected steel columns vs partially encased columns: Fire resistance and economic considerations
(Elsevier, 2016)
As is commonly known, resistant properties of steel columns decrease quickly with an increase in temperature. Thus, steel columns are usually surrounded with low thermal conductivity materials that protect them at high ...
Evaluation of R448A and R450A as low-GWP alternatives for R404A and R134a using a micro-fin tube evaporator model
(Elsevier, 2016-04-05)
When retrofitting new refrigerants in an existing vapour compression system, their adaptation to the heat exchangers is a major concern. R450A and R448A are commercial non-flammable mixtures with low GWP developed to replace ...
Synchronous communication in PLM environments using annotated CAD models
(Springer Verlag, 2016-06)
The connection of resources, data, and knowledge through communication technology plays a vital role in current collaborative design methodologies and Product Lifecycle Management (PLM) systems, as these elements act as ...
Options for labelling circular products: Icon design and consumer preferences
(Elsevier, 2018-11)
The demand of products that incorporate circular requirements depend on consumer perceptions. So effective communication is necessary between the product and consumers through product labelling. The use of specific icons ...
Experimental study of critical heat flux in flow boiling under subatmospheric pressure in a vertical square channel
(Elsevier, 2019-03)
Critical Heat Flux (CHF) is the maximal limit of heat flux in two-phase nucleate boiling heat transfer; therefore, an understanding of CHF under a wide range of conditions is important for safe system operation. In this ...
Environmental performance of alternative end-of-life scenarios for electrical and electronic equipment: A case study for vacuum cleaners
(Elsevier, 2017-08)
Extending the product life span of electrical and electronic equipment is considered an optimal strategy for resource conservation as consuming new resources to produce new appliances is avoided, and the amount of generated ...
Consumer attitude towards the repair and the second-hand purchase of small household electrical and electronic equipment. A Spanish case study
(Elsevier, 2017-08)
This study presents a survey to identify current habits and practices regarding the repair and second-hand purchases of small household electrical and electronic equipment (EEE) in Spain, and to identify the profile of ...
Comparison of the carbon footprint of different patient diets in a Spanish hospital
(Sage, 2015)
Abstract
Objectives:
Mitigating climate change requires management strategies to reduce greenhouse gas emissions in any
sector, including the health system. Carbon footprint calculations should play a key role in ...
A survey on consumers’ attitude towards storing and end of life strategies of small information and communication technology devices in Spain
(Elsevier, 2017)
This study analyses the current habits and practices towards the store, repair and second-hand purchase of small electrical and electronic devices belonging to the category of information and communication technology (ICT). ...
