Variable Refrigerant Flow Systems by Napoleon Enteria,Takao Sawachi,Kiyoshi Saito Pdf

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.

HVAC - Variable Refrigerant Flow (VRF) Systems by A. Bhatia Pdf

VRF (Variable refrigerant flow) is an air-condition system configuration where there is one outdoor condensing unit and multiple indoor units. The term variable refrigerant flow (VRF) refers to the ability of the system to control the amount of refrigerant flowing to the multiple evaporators (indoor units), enabling the use of many evaporators of differing capacities and configurations connected to single condensing unit. The arrangement provides an individualized comfort control, and simultaneous heating and cooling in different zones. Currently widely applied in large buildings especially in Japan and Europe, these systems are just starting to be introduced in the U.S. The VRF technology/system was developed and designed by Daikin Industries, Japan who named and protected the term variable refrigerant volume (VRV) system so other manufacturers use the term VRF "variable refrigerant flow". In essence both are same. With a higher efficiency and increased controllability, the VRF system can help achieve a sustainable design. Unfortunately, the design of VRF systems is more complicated and requires additional work compared to designing a conventional direct expansion (DX) system. This 3 -hour quick book provides an overview of VRF system technology. Emphasis is placed on the control principles, terminology, basic components, advantages and design limitations. This course is aimed at the personnel who have some limited background in the air conditioning field and is suitable for mechanical, electrical, controls and HVAC engineers, architects, building designers, contractors, estimators, energy auditors and facility managers.The course includes a multiple-choice quiz consisting of fifteen (15) questions at the end. Learning ObjectiveAt the conclusion of this course, the reader will: * Understand the difference between multi-split air conditioning system and VRF systems;* Understand the operating principle of direct expansion split and VRF system;* Understand the concept of thermal zone;* Understand how VRF with heat recovery are different from ordinary heat pump systems;* Understand the operation of thermostatic expansion valve (TXV) and electronic expansion valve (EEV);* Understand the influence of building characteristics and load profile on selection of VRF system;* Learn the advantages and application of VRF systems;* Understand the design limitations and challenges in design of VRF systems.

Auravana Habitat System by Auravana Pdf

This publication is the Habitat System for a community-type society. A habitat (a.k.a., city, town) is a material-operational service environment where humans live and have their needs fulfilled. It is a service composed of interacting material objects. This habitat system standard identifies the services, technologies, components, and processes that compose a habitat service system. A habitat service system encodes and expresses humanity's decided material fulfillment services. When a decision resolves into a service, that service is specified to exist in the habitat system. Different configurations of a habitat lead to different levels and qualities of fulfillment. The coherent integration and open visualization of the habitat system is important for human requirements to be met at the local and global level through scientific planning. This standard represents the encoding of decisions into a global habitat service system with many local configurations of habitat that act together as a fulfillment platform for the whole community population. The visualization and simulation of humanity’s interconnected habitat systems is essential for maintaining a set of complex, fulfillment-oriented constructions and operations that meet human fulfillment requirements. This publication details what has been, what is, and what could be constructed in the material environment. It depicts through language and symbols, visualization, and simulation, a habitat service environment consisting of life, technology, and exploratory support services. For anything that is to be constructed in the material system, there is a written part, a drawing part, and a simulation part, which is also how the material system is sub-divided. Further, all habitats are designed and operated by means of master planning; they all have a master plan.

Low-carbon City and New-type Urbanization by Songlin Feng,Weiguang Huang,Jun Wang,Mingquan Wang,Jun Zha Pdf

In the face of increasingly serious resource and environmental challenges, the world has already accepted low-carbon development as the main way forward for future city construction. Chinese cities have encountered many problems during their development, including land constraints, energy shortages, traffic congestion and air pollution. For this reason, the national meeting of the Central Work Conference on Urbanization made the strategic decision to take a new approach to urbanization and indicated that in future the key features of urbanization in China will be low-carbon development and harmony between the environment and resources. This book discusses the "low-carbon city" as the new pattern of Chinese urbanization. This represents a major change and takes "intensive land use,” “intelligent,” “green” and “low carbon" as its key words. Low carbon will become an important future development direction for Chinese urbanization development. In the twenty-first Century in response to the global climate change, countries have started a wave of low-carbon city construction. But in China, there are still many disputes and misunderstandings surrounding the issue. Due to a lack of research, low-carbon city construction in China is still in the early stages, and while there have been successes, there have also been failures. There are complex and diverse challenges in applying low-carbon development methods in the context of today’s Chinese cities. The construction of low-carbon cities requires efficient government, the technological innovation of enterprises, and professional scholars, but also efforts on the part of the public to change their daily activities. Based on the above considerations, the collection brings together experts from urban planning and design, clean-energy systems, low-carbon transportation, new types of city infrastructure and smart cities etc., in the hope of forming some solutions for Chinese low-carbon city development.

Advanced Controls for Intelligent Buildings by Siddharth Goyal Pdf

This book focuses primarily on both technical and business aspects needed to select, design, develop and deploy control application (or product) successfully for multiple components in building systems. Designing and deploying a control application require multiple steps such as sensing, system dynamics modelling, algorithms, and testing. This may involve choosing an appropriate methodology and technique at multiple stages during the development process. Understanding the pros and cons of such techniques, most importantly being aware of practically possible approaches in the entire ecosystem, is critical in choosing the best framework and system application for different parts of building systems. Providing a wide overview of the state-of art in controls and building systems, providing guidance on developing an end-to-end system in relation to business fundamentals (distribution channels, stakeholders, marketing, supply-chain and financial management), the book is ideal for fourth-year control/mechanical/electrical engineering undergraduates, graduate students, and practitioners including business leaders concerned with smart building technology.
