Abstract

The commercial sector consumes over 13 quads of primary energy annually. Most of this consumption (two-thirds) meets the energy needs of lighting and heating, ventilation, and air-conditioning. The largest consuming group of the remaining one-third is commercial refrigeration at about one quad annually (990 trillion Btu), valued at over $7 billion per year to the commercial sector consumer. Potential energy savings are estimated to be about 266 trillion Btu, with consumer savings valued at about $2 billion. This study provides the first known estimates of these values using a bottom-up approach. The authors evaluated numerous self-contained and engineered commercial refrigeration systems in this study, such as: supermarket central systems, beverage merchandisers, ice machines, and vending machines. Typical physical characteristics of each equipment type were identified at the component level for energy consumption. This information was used to form a detailed database from which they arrived at the estimate of 990 trillion Btu energy consumption for the major equipment types used in commercial refrigeration. Based on the implementation of the most cost-effective technology improvements for the seven major equipment types, they estimated an annual potential energy savings of 266 trillion Btu. Much of the savings can be realized with the implementationmore »« less

Application of Best Industry Practices to the Design of Commercial Refrigerators

Technical Report

The substantial efficiency improvements which have been realized in residential refrigerators over the last twenty years due to implementation of the National Appliance Energy Conservation Act and changing consumer reactions to energy savings give an indication of the potential for improvement in the commercial sector, where few such efficiency improvements have been made to date. The purchase decision for commercial refrigerators is still focused primarily on first cost and product performance issues such as maximizing storage capacity, quick pulldown, durability, and reliability. The project applied techniques used extensively to reduce energy use in residential refrigeration to a commercial reach-in refrigerator.more »« less

Permanent Magnet Synchronous Motors for Commercial Refrigeration (Final Report)

Technical Report Fricke, Brian; Becker, Bryan

This report provides background information on various fractional-horsepower electric motor technologies used for evaporator fan applications in commercial refrigeration and summarizes data from a DOE-sponsored evaporator fan motor laboratory and field demonstration project. This report also extrapolates that data to project the potential economic and environmental benefits resulting from upgrading the current installed base of commercial refrigeration evaporator fan motors to permanent magnet synchronous (PMS) motors.Evaporator fan motors used in commercial refrigeration applications are fractional horsepower in size, responsible for moving air across the evaporator coil, and typically run at one speed. Historically, shaded-pole induction motors have been the mostmore »« less

A roadmap for simultaneously developing the supply and demand for energy-efficient beverage vending machines

Conference Horowitz, N; Dolin, J; Suozzo, M; ...

Refrigerated beverage vending machines (vending machines) present a previously untapped opportunity for significant energy savings. In the US there are about 2.5 million vending machines in the field and new machine sales exceed 250,000/year. Existing vending machines consume approximately 7.5 billion kWh/year and cost $600 million/year to power. Initial estimates suggest that approximately 3.5 kWh/day can be saved per machine through refrigeration and lighting energy efficiency improvements alone, most of which have already proven successful in other applications. Over the ten year machine life, the approximate per machine savings are 13,000 kWh, electric bill savings of $910, and carbon dioxidemore »« less
Connected Loads – Grid Connected Appliances: Deployment IoT Solution for Fault Detection and Diagnostics

Technical Report Sun, Jian; Kuruganti, Teja; Fricke, Brian; ...

As one of the most energy-intensive end-uses in the commercial buildings sector, supermarkets consume around 50 kWh/ft² ( or 537.6 kWh/m²) of electricity annually, or more than 2 million kWh of electricity per year for a typical store. The biggest consumer of energy in a supermarket is its refrigeration system, which accounts for 40–60% of its total electricity usage and is equivalent to about 2–3% of the total energy consumed by commercial buildings in United States, or around 0.5 quadrillion Btu (or 0.53 quadrillion KJ). Also, the supermarket refrigeration system is one of the biggest consumers of refrigerants. Current supermarketmore »« less

The potential for energy-efficient technologies to reduce carbon emissions in the United States: Buildings sector

Conference Koomey, J; Levine, M; Martin, N

Energy is used in buildings to provide a variety of services to users such as lighting, space heating and cooling, refrigeration, and electricity for electronics and other equipment. In the US building energy consumption accounts for nearly one third of total primary energy consumption and related greenhouse gas emissions. The cost for these energy services, or end-uses, was over $200 billion in 1997. This paper summarizes a detailed assessment of the achievable cost-effective potential for reducing carbon dioxide emissions in 2010 in the US residential and commercial buildings sector based on the preliminary results of a study completed by themore »« less
