The ASHRAE Handbook is published in a series of four volumes, one of which is revised each year, ensuring that no volume is older than four years.
TC 10.7 is responsible for developing and maintaining the following chapters in the ASHRAE Handbook.
REFRIGERATION: "Retail Food Store Refrigeration and Equipment "
In the United States, almost 200,000 retail food stores operate their refrigeration systems around the clock to ensure proper merchandising and safety of their food products. Supermarkets and convenience stores make the largest contribution to this total (Food Marketing Institute 2004). In U.S. retail food stores, refrigeration consumes about 2.3% of the total electricity consumed by all commercial buildings (EIA 2003). Refrigeration accounts for roughly 50% of the electric energy consumption of a typical supermarket (Arthur D. Little1996).
REFRIGERATION: "Food Service and General Commercial Equipment"
Food service requires refrigerators that meet a variety of needs. This chapter covers refrigerators available for restaurants, fast-food restaurants, cafeterias, commissaries, hospitals, schools, convenience stores, grocery stores, and other specialized applications. Many refrigeration products used in food service applications are self-contained, and the corresponding refrigeration systems are conventional. Some systems, however, do use ice for fish, salad pans, or specialized preservation and/or display. Chapters 15 and 17 have further information on some of these products.

Comment on the Handbook: ASHRAE welcomes your comments on the Handbook or a specific Handbook chapter. To submit a comment about any aspect or part of the Handbook series, you can use the Handbook Comment Form.
Review a Handbook Chapter: To provide your feedback about a specific Handbook chapter, you can answer the brief survey questions on the Handbook Chapter Review Form.
Technical Committees develop and sponsor technical sessions at the winter and annual conferences. Information about their future technical program is discussed at each TC meeting and at the TC’s Program Subcommittee meeting.
ASHRAE publishes papers and transactions from presentations at its conference events. In addition, ASHRAE records most of the seminar sessions from its conferences on DVD. These DVDs are ideal for use at chapter meetings, in university courses, or company lunch and learns. Products available from the most recent conference may be found here.
At the most recent annual meeting, the TC sponsored the following sessions:
Seminar 37: Lower GWP Alternatives for R-404A in Commercial and Transport Refrigeration
Chair: Brian Fricke, Ph.D., Member, Oak Ridge National Laboratory, Oak Ridge, TN
When commercial and transport refrigeration systems began shifting away from HCFC refrigerants to HFC refrigerants,
R-404A became the refrigerant of choice and the industry standard HFC. However, with an extremely high GWP, there is now an industry-wide demand for R-404A replacement refrigerants, driven by recent and proposed changes in regulations,such as the EU F-Gas Regulations and EPA SNAP. Beyond suitable replacement refrigerants, there is a need to understand how these new refrigerants will behave in existing systems and what changes will be required in design practice, construction and commissioning for all systems. This seminar presents experimental results for new lower GWP refrigerant alternatives and discusses how characteristics such as temperature glide and mild flammability may be managed.
1. Challenges in Retrofitting R-404A with Lower GWP Refrigerants
Sarah Kim, Arkema, Inc., King of Prussia, PA
2. Evaluation of Low-GWP Replacements for R-404A in Refrigeration Systems
Gustavo Pottker, Member, Honeywell - Buffalo Research Laboratory, Buffalo, NY
3. Retrofit Testing of Low GWP Alternatives for Commercial and Transport Refrigeration
Barbara Minor, Member, DuPont, Wilmington, DE
4. Lower GWP Options for R-404A in Transport Refrigeration Applications
Chris Repice, Member, Carrier Transicold, East Syracuse, NY
Technical Committees are responsible for identifying, proposing, selecting bidders, and monitoring research projects funded by ASHRAE. Information about their specific research program is discussed at each TC meeting and at the TC’s Research Subcommittee meeting.
The following are abstracts for TC 10.7's research projects which are underway:
1467-RP BALANCING LATENT HEAT LOAD BETWEEN DISPLAY CASES AND STORE COMFORT COOLING
The overall objective of this project is to provide a comprehensive assessment of the potential for energy savings in supermarkets by optimized design and operation of the combined HVAC and refrigeration systems. The assessment will include the effects of climate, space temperature and humidity set-point controls, HVAC system type and characteristics, and the design and operation of the refrigerated cases.
1615-RP FAULT DETECTION AND DIAGNOSTIC (FDD) METHODS FOR SUPERMARKETS- PHASE I
TC 7.5 with TC10.07 as Co-Sponsor
This research directly addresses the concept of sustainability. The supermarket sector has a significant impact on global warming, not only from the point of view of energy consumed but, even more importantly, from the point of view of the impact of leaked refrigerant.
ASHRAE writes standards for the purpose of establishing consensus for: 1) methods of test for use in commerce and 2) performance criteria for use as facilitators with which to guide the industry. ASHRAE publishes the following three types of voluntary consensus standards: Method of Measurement or Test, Standard Design and Standard Practice. ASHRAE does not write rating standards unless a suitable rating standard will not otherwise be available. ASHRAE is accredited by the American National Standards Institute (ANSI) and follows ANSI's requirements for due process and standards development. Standards may be purchased at the ASHRAE On-line Bookstore.
These standards may be purchased at the ASHRAE by clicking on the title.

ASHRAE Technical FAQs are provided as a service to ASHRAE members, users of ASHRAE publications, and the general public. While every effort has been made to ensure their accuracy and reliability, they are advisory and provided for informational purposes only, and in many cases represent only one person’s view. They are not intended and should not be relied on as an official statement of ASHRAE.

Presently TC 10.7 participates on the following Multidisciplinary Task Groups:
MTG Lower Global Warming Potential Alternative Refrigerants
MTG.LowGWP is established to coordinate TC/TG/TRG technical activities to help transition the HVAC&R industry to sustainable lower Global Warming Potential (GWP) alternative refrigerants. The MTG will further request participation from US EPA and AHRI. The MTG responsibilities include suggestions for research, development and presentation of technical programs of all types on alternative lower GWP refrigerants, suggestions for Life Cycle Climate Performance (LCCP) systems evaluation for different applications, development of lower GWP solutions for different applications, and a special publication detailing aspects of LCCP applied to the HVAC&R fields.
