Book Description
This project was funded by SCE's Emerging Technologies Program, and evaluates the feasibility of a connection system that can pave the path to accelerated, cost-effective adoption of high-efficiency Minisplit Heat Pump (MSHP) systems. This report details the characterization of this connection system and a heat pump enabled with this technology in a laboratory setting, and assesses the energy and cost impact applicable to residential buildings in SCE service territory. The energy and economic analysis leverages NREL's ResStock (TM) modeling approach based on the EnergyPlus (R) hourly simulation platform. The connection system can be incorporated into existing MSHP architectures. This reduces installation time from 10 to 20 man hours to approximately one hour or less, dramatically lowering total installation costs without adversely impacting heat pump performance. This report characterizes the connection system's leakage performance while connected and disconnected, as well as leakage over several connection/disconnection cycles, commensurate with manufacturer specifications for the individual components. The connector was incorporated into an off-the-shelf MSHP. Performance was compared to an identical unmodified heat pump. The connector had no impact on performance. Large-scale hourly energy simulations were performed for 22,574 homes across 15 counties in SCE service territory. The analysis was performed using baseline assumptions about the penetrations of window air conditioners (~18%) and six upgrade scenarios for these air conditioners. All scenarios assumed 100% adoption of the Connector-Supported Heat Pump (CSHP) in place of window air conditioners: MSHPs at Seasonal Energy Efficiency Ratio (SEER) 17, 25, and 33, and CSHPs at SEER 17, 25, and 33. Results show the increased adoption of high-efficiency heat pumps can result in up to 29% air conditioning energy savings for homes with window air conditioners.

Book Description
When Thomas Edison began wiring New York City with a direct current electricity distribution system in the 1880s, he gave humankind the magic of electric light, heat, and power; in the process, though, he inadvertently opened a Pandoras Box of unimaginable illness and death. Dirty Electricity tells the story of Dr. Samuel Milham, the scientist who first alerted the world about the frightening link between occupational exposure to electromagnetic fields and human disease. Milham takes readers through his early years and education, following the twisting path that led to his discovery that most of the twentieth century diseases of civilization, including cancer, cardiovascular disease, diabetes, and suicide, are caused by electromagnetic field exposure. In the second edition, he explains how electrical exposure does its damage, and how electricity is causing our current epidemics of asthma, diabetes and obesity. Dr. Milham warns that because of the recent proliferation of radio frequency radiation from cell phones and towers, terrestrial antennas, Wi-Fi and Wi-max systems, broadband internet over power lines, and personal electronic equipment, we may be facing a looming epidemic of morbidity and mortality. In Dirty Electricity, he reveals the steps we must take, personally and as a society, to coexist with this marvelous but dangerous technology.

Book Description
The demand for inverter mini split system installations is growing rapidly due to the versatility, functionality, and electrical efficiency of these units. As a result, inverter mini split system installations and servicing are becoming more common for individuals in the HVACR trade. Technicians must know the step-by-step service procedures associated with these systems and how they differ from traditional single speed systems. This book was written to help demystify the operation of inverter mini split systems and to explain associated concepts and procedures, in a language that is easy to understand. System parts are examined individually, electrical/mechanical operation is discussed, and related troubleshooting steps are given. By examining each component individually, readers can more easily digest the information and build upon their knowledge, as they progress through the text. The goal of this book is to equip technicians with the knowledge they need to service these complex systems. Procedures Included: · Line Set Connection · Leak Testing and Vacuuming · Charging and Recovery · Guidance on Checking the Charge · Power and Communication Wiring · Electrical Component Troubleshooting · Common Problems and Diagnosis

Book Description
Preface Selecting the proper HVAC (Heating, Ventilation, and Air Conditioning) equipment for your project is crucial for ensuring energy efficiency, comfort, and cost-effectiveness. This preface will provide an overview of key considerations and steps involved in choosing the right HVAC system for your specific needs. Understanding HVAC Systems HVAC systems are integral to maintaining indoor air quality and thermal comfort. They include components for heating, cooling, ventilation, and humidity control. Common types of HVAC systems include: Split Systems: Separate indoor and outdoor units, ideal for individual room control. Packaged Systems: All-in-one units, typically used in commercial applications. Heat Pumps: Efficient for both heating and cooling, suitable for moderate climates. Ductless Mini-Splits: Offer flexibility without ductwork, ideal for retrofits or specific zones. Key Considerations Project Scope and Requirements: Size and Layout: The size and layout of the space influence the type and capacity of the HVAC system needed. Larger or multi-story buildings may require more complex systems. Usage: Determine the primary use of the space (e.g., residential, commercial, industrial) and any specific needs such as server rooms, labs, or manufacturing areas. Climate: Local climate conditions significantly affect HVAC requirements. Hot and humid climates demand efficient cooling and dehumidification, while colder regions prioritize heating. Energy Efficiency: Look for systems with high Seasonal Energy Efficiency Ratio (SEER) and Heating Seasonal Performance Factor (HSPF) ratings. Energy-efficient systems reduce operating costs and environmental impact. Consider systems with variable speed technology for better energy management. Budget: Balance initial investment with long-term operational costs. High-efficiency systems may have higher upfront costs but lower ongoing expenses. Building Codes and Regulations: Ensure compliance with local building codes, standards, and regulations. This includes safety standards, energy efficiency mandates, and environmental regulations. Indoor Air Quality: Choose systems with good filtration and ventilation capabilities to maintain healthy indoor air quality, especially in spaces with high occupancy or specific air quality requirements. System Design and Integration: Proper design and integration with existing building systems (electrical, plumbing, etc.) are crucial for optimal performance. Consider consulting with HVAC professionals or engineers. Future Scalability: Plan for potential future expansions or modifications. Select systems that can be easily upgraded or expanded. Steps to Select the Proper HVAC Equipment Assess the Building Load: Conduct a load calculation to determine heating and cooling requirements. This includes considering insulation, windows, occupancy, and internal heat gains. Evaluate Different HVAC Systems: Compare various systems based on efficiency, capacity, and suitability for the project's specific needs. Consider Technological Features: Look for modern features such as smart thermostats, zoning capabilities, and remote monitoring for enhanced control and efficiency. Consult with Professionals: Engage HVAC contractors, engineers, or consultants to review your plans and provide expert recommendations. Review Manufacturer Warranties and Support: Choose reputable manufacturers that offer robust warranties and reliable customer support. Conclusion Selecting the proper HVAC equipment is a multifaceted process that requires careful consideration of the project's specific requirements, climate, energy efficiency, and budget. By following a systematic approach and leveraging professional expertise, you can ensure that your HVAC system will provide optimal performance, comfort, and cost-efficiency for your project.
