The performance of an ASHP system using waste air to recover heat energy in a subway system

In this short communication, we demonstrate that the performance of a typical air source heat pump (ASHP), exploiting a relatively stable air temperature within a subway environment, is high, even during the peak heating months. After a nine-month operational run, the coefficient of performance is demonstrated to be 3.5. The design and installation difficulties are stated together with the lessons learnt following this trial. The actual energy and carbon savings are discussed

Competing Concerns in Welfare Technology Innovation: A Systematic Literature Review

Welfare technologies (WT) such as telecare and service robots are expected to improve and even radically transform service delivery in health- and eldercare. Yet despite political awareness and financial investments, many studies report promising inventions that fail to become implemented on a larger scale. Current research draws a fragmented and heterogeneous picture of this problem, with divergent implications for practice. In this article, I review and discuss the extant literature and identify eight competing concerns that are central to how WT can become implemented on a large scale. By highlighting and contrasting practical and theoretical positions in this emerging and interdisciplinary research topic, I contribute conceptually to the understanding of the competing concerns in WT innovation that managers and policy-makers must balance in order to support the critical transition from small-scale invention to large-scale implementation

Competing Concerns on Emerging Welfare Technologies. A review of eight prevailing debates in current literature

Welfare technologies (WT) such as telecare, service robots, and other digital innovations for public sector service delivery are expected to improve and even radically transform health- and eldercare. However, despite political awareness and financial investments, many studies report promising inventions that fail to become implemented on a larger scale. Current research draws a fragmented and heterogeneous picture of this problem, with divergent implications for practice. This article reviews and discusses the extant literature to identify eight competing concerns central to how WT can become implemented on a large scale. By highlighting and contrasting practical and theoretical positions in this emerging and interdisciplinary research topic, the review contributes to understanding the complexities that managers and policy-makers must address to diffuse and sustain WT innovations from small to large scale

Organizing for Emerging Welfare Technology: Launching a Drug-Dispensing Robot for Independent Living

Emerging technologies, such as robots, virtual homecare, and sensor technologies, have considerable potentials to transform health- and eldercare. These so-called welfare technologies (WTs) are expected to increase the quality of services, empower citizens, improve working conditions for professionals, and reduce costs for care providers. However, as this transformation this involves both technological development and radical changes in how these services are organized, many promising WTs fail to advance beyond the pilot stage and create value on a large scale. This paper reports the results of a longitudinal case study of the emergence of a service robot in primary healthcare, from project launch to testing, development, and evaluation. Seeking new ways of organizing emerging technologies, nine Danish municipalities and a consortium of four private companies launched a collaborative project, aiming to develop and implement the use of a drug-dispensing robot for patients living at home. The analysis traces how project managers respond to competing concerns on innovation strategy, testing, coordination, and user mobilization and how these critical decisions shape the project’s trajectory. As such, the paper sheds new light on how to understand and manage competing concerns in the process of organizing emergent WTs

Heat energy from a shallow geothermal system in Glasgow, UK: performance evaluation design

This study reports on the actual energy and economic performances of a water source heat pump recently installed and operated at a Glasgow Subway station in the UK using subsurface water ingress to provide heating and domestic hot water. This follows from a previous publication that detailed the empirical measurements and design of a heating system designed on the basis of a 15-month monitoring period of the water flow and temperature. The perennial water flow at a relatively high temperature enabled the system to operate more efficiently than a typical heat pump system with boreholes or trenches. The performance of the water source heat pump has been monitored for a 4-month period, and the coefficient of performance as well as the energy saving is reported in the present study. The findings of this study not only indicate the energy, carbon dioxide and financial benefits of the heating system, but also highlight key issues during the operation in such a demanding underground environment. Further renewable heat potentials for the rest of the subway network and opportunities to commercialise the excess heat energy output are explored. </jats:p
