Kiyoshi Saito – författare

Kiyoshi Saito, a leading heat pump researcher, provides a comprehensive guide to this technology and its related trends, issues, and policies. Using a solutions-driven approach, this book provides a roadmap for building carbon-neutral and recycling-oriented societies with the help of heat pump technology.Situated in the context of advanced initiatives taking place in Japan, the book addresses the expansion of heat pump technology in recent years and the extension of its application into fields such as industrial and environmental technology. In doing so, it discusses not only technical but also digital aspects to explore various challenges related to the functioning of heat pumps, such as energy conservation and refrigerant leakage. Saito underscores the importance of holistic and practical solutions that take into account individual factors (such as increased equipment size, increased refrigerant consumption, and increases in product prices) to secure resources and optimize the value chain with the larger goal of building a circular economy and a decarbonised society. By offering valuable recommendations that involve technological solutions as well as policy initiatives, this book emphasizes the importance of heat pump technology in efficiently converting electricity and power into cooling and heating, and its indispensability in achieving carbon neutrality for building a more sustainable future.This book is an essential guide for graduate and postgraduate students as well as consumers and corporate engineers in the field. It is also an invaluable resource for governments and civil-society organizations working towards the realization of a circular economy.

This book compiles the latest research, development, and application of VRF systems with contributions from various experts who pioneered and contributed to the development of the VRF system. This book presents the fundamental issues related to the real application and behaviour of the VRF system based on the long-term monitoring of the installed system. With our experience of pandemic which COVID-19 is an airborne, the spread of the virus is very fast. With this, the heating, ventilating and air-conditioning (HVAC) system is a major player in the maintenance and control of indoor environment to minimize the spread of the virus. As the variable refrigerant flow (VRF) system is a versatile HVAC system in which it can operate at different conditions, the application of the VRF system is very important to control the indoor environmental conditions. Thus, the publication of this book is important with the present situation and the future possible situation which the control of indoor spaces is very important. With this, this book will serve as a reference for building designer, contractors, building regulators and students.
