Grocery stores are among the most energy-intensive commercial buildings, consuming two to three times as much energy per unit floor area as offce buildings. The single-largest energy end use component of grocery building consumption is refrigeration. In current practice, most of the energy extracted from refrigerated cases and walk-in coolers is rejected to the outdoors. Signifcant gains in effcient operation of grocery stores can be achieved by recovering this rejected heat to meet various lowgrade heating requirements within the stores. The recent Advanced Energy Design Guide for Grocery Stores: Achieving 50% Energy Savings Toward a Net Zero Energy Building1 offers a number of ways the design of the refrigeration and HVAC systems in grocery stores may be integrated to achieve this savings.

During power outages servers in the data centers are generally powered by uninterruptible power supplies (UPS). At the same time the sources for active cooling such as CRACs, CRAHs, and chillers stop operating for a period until powered by alternate power sources. During this period servers continue to generate heat without any active cooling. This results in increase in the room air temperature within a short period that can be detrimental to the servers. This paper, with the help of a mathematical model, indicates that the rate of heating of a data center can start initially at a certain maximum level, and can then gradually reduce to a certain minimum level, which is the lowest possible rate of heating that a data center can attain. The rate of such exponential decay is a function of the time constant, which is the characteristic of a data center design and layout. The time constant depends on the heat capacity ratio and the specific surface area of racks in a data center. This paper analyzes various factors that affect these parameters and demonstrates how the time constant can be employed as a matrix to compare the thermal performance of data centers during the power outage period. © 2011 ASHRAE.

Electric motors are the universal drivers of HVAC components. With a few exceptions, such as steam turbine-driven chillers and combustion engine driven chillers, electric motors, ranging in size from fractional horsepower to thousands of horsepower, provide the driving forces for HVAC systems. Many different types of motors are suitable for many conditions such as high and low temperature, moisture, high humidity, and/or corrosive or explosive environment.

ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, has evolved rapidly over the years. As it has evolved, the requirements have changed, and some of these requirements have been overlooked by the engineering community. Some of these requirements are mandatory, meaning they must be incorporated on all projects for which they are applicable, and others are prescriptive. Copyright 2016 ASHRAE.

Direct-expansion (DX) cooling and heat pump systems have often been the less- respected alternative for building conditioning compared with hydronic systems. In general, they are considered to be a "cheaper" system, with higher maintenance cost, shorter lifespan, limited controllability and lower energy efficiency. On the other hand, they are often more convenient, more amenable to design-build procurement, and less demanding of operator expertise.

During power outage servers in the data centers are powered by uninterrupted power supply (UPS). At the same time, the cooling system components such as CRACs, AHUs, and chillers stop operating for a short period until powered by alternate power sources. During this period servers continue generating heat in the data center room without active cooling. It is common notion that data centers contain large thermal mass, and hence, large heat capacity in the steel rack enclosures to protect servers from the thermal shock due to rising room air temperatures. However, the rate of air temperature rise and the availability of rack thermal mass depend on several factors including the height of the data center room, number of rack enclosures and their size, number of rack rows and their layout, and heat load density of a data center. It is crucial for design engineers and facility managers to know how much time can be available for restarting the active cooling systems before servers reach automatic shutoff temperatures. With the help of a heat transfer model this paper systematically analyzes the effect of various parameters and the impact of rack thermal mass on the time that air requires to reach the thermal shutoff threshold temperature. ©2010 ASHRAE.
