HIGH PERFORMANCE COMMERCIAL KITCHEN VENTILATION SYSTEMS

©2014 This excerpt taken from the article of the same name which appeared in ASHRAE Journal, vol. 56, no. 11, November 2014.

By Don Fisher, P.Eng., Associate Member ASHRAE; and Rich Swierczyna, Associate Member ASHRAE

About the Authors Don Fisher, P.Eng., is a partner at Fisher Consultants, and Rich Swierczyna is senior engineer and CKV lab manager with Fisher-Nickel, at the PG&E Food Service Technology Center in San Ramon, Calif.

The energy use intensity associated with operating commercial kitchen ventilation (CKV) systems is well recognized within the HVAC design community and food service industry. This operating cost burden has stimulated energy efficiency design concepts in recent years, including the application of demand-controlled kitchen ventilation (DCKV). Over the past two and a half decades, ASHRAE Technical Committee 5.10, Kitchen Ventilation, developed and maintained a robust Handbook Chapter2 while its affiliated Standing Standards Project Committee (SSPC) 154 has promulgated ASHRAE Standard 154, Ventilation for Commercial Cooking Operations. This standard has been a catalyst and technical foundation for overhauling the kitchen ventilation section in the International Mechanical Code (IMC).

Effective 2010, ASHRAE Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, has embraced specific requirements for commercial kitchen ventilation. Subsequently, California Title 24 incorporated similar requirements commencing in 2014.

Unfortunately, the industry effort to increase the energy efficiency of CKV systems has not had a corresponding impact on improving thermal comfort within kitchens. In striving to reduce energy consumption, engineers have had a long-standing tendency to minimize (or avoid) tempering makeup air, often compromising thermal comfort in the kitchen. Everyone (from employees to design professionals) has acknowledged that commercial kitchens represent a hot working environment, but documentation of sensible and radiant temperatures in commercial kitchens did not exist within the public domain. In response, ASHRAE funded a research project titled Thermal Comfort in Commercial Kitchens5 that quantified the relatively extreme thermal conditions in 100 commercial kitchens (Figure 1).

The goal of this article is to discuss the new Standard 90.1 requirements in context with designing energy efficient CKV systems that strive to

https://www.ashrae.org/resources--publications/periodicals/ashrae-journal/features/90-1-and-designing-high-performance-commercial-kitchen-ventilation-systems#figure1



e-NEWSLETTER improve comfort conditions in kitchens. Complementary to this article is a publication by the Department of Energy, which also reviews the requirements in Standard 90.1 for kitchen exhaust.6 Readers are invited to download this publication as a complement to our perspective on high-performance CKV systems.

And just what does “high performance” mean with respect to a CKV system? We believe that it means a system where the exhaust hood completely captures and contains cooking effluent, where the associated noise levels and energy costs are minimized, and where thermal comfort in the kitchen is consistent with good engineering practices and workplace standards. The format we have chosen for this article is to copy the appropriate sections in Standard 90.1 (shown in italics), followed by our interpretation and supporting industry information. In some cases, we also have paraphrased rational that was included in the foreword to the public review draft of this addendum as it no longer resides within the Standard.

EFFICIENT LABS FOR UNIVERSITY

©2014 This excerpt taken from the article of the same name which appeared in ASHRAE Journal, vol. 56, no. 11, November 2014.

e-NEWSLETTER Because the mechanical system supplying the lab area of the Otto Maass Building at McGill University in Montreal had not been renovated since 1964, the building was one of the largest energy consumers on campus. Following a renovation, building energy consumption dropped from 13% to 5% of the total energy consumed on the entire campus.

Sixty percent of the building’s 140,000 ft2 (13 000 m2) is labs. Prior to renovation, in the laboratory area the average fume hood density was 19 chemical fume hoods per 5,000 ft2(465 m2). The building’s ventilation system operated at a constant flow rate of 135,000 cfm (63 700 L/s) and operated 24/7. Steam was generated from the power plant (natural gas) and a 850 ton (2990 kW) local chiller was located in the penthouse.

Renovation

The 2009 renovation included 37,500 ft2 (3500 m2) of laboratories and all mechanical rooms and distribution shafts serving laboratory areas. The objectives of the project were to improve safety and comfort for the users, increase energy efficiency and flexibility, and maintain operations while retrofitting labs. The building had to be highly energy efficient while providing improved air quality to occupants and minimizing impact on the environment. Design conditions in Montreal are –20°F (–28.9°C) in winter and 88°F dry bulb/75°F wet bulb (31.1°C/23.9°C) in summer.

The biggest concern was maintaining a safe, secure, and healthy environment for users while replacing all HVAC equipment. One solution was to install temporary HVAC systems in the courtyard to supply the spaces that were left occupied.

To provide adequate air quality to researchers and students, it was necessary to carry out the work in phases. Four temporary 100% fresh air ventilation systems with a total capacity of 120,000 cfm (56 600 L/s) were installed outside the building to ensure a high level of air quality to the users. Temporary supply and exhaust ducts were installed on the exterior walls all around the building and served each occupied room.

During the year-long project laboratory work had to be carefully planned and scheduled so researchers had enough lab space to continue their experiments. At the end of the project, a total of 150,000 cfm (70 800 L/s) of capacity were installed (six supply systems of 25,000 cfm [11 800 L/s] each at 100% fresh air and six exhaust systems of similar capacity).

The energy efficient installations included:

VAV terminal devices and fume hood; Motion sensors for light and fumes hoods; Ventilation and fume hood face velocity; Runaround glycol heat recovery loop; Low temperature terminal reheat; Low velocity system; Reuse of office air for minimum ach required

in lab space; Precooling of exhaust air; and Heat recovery from major server room

located in the adjacent building ( ±520,1 kBtu/h [300 kW] ) 24/7.

JOIN THIS WORKSHOP: IMPORTANCE OF REFRIGERATION - AND ICE CREAM - FOCUS OF ASHRAE CONFERENCE

.

ATLANTA - From Cherry Garcia to Sea Salt Caramel, Americans love their ice cream. Nearly 9 percent of cow´s milk produced in the United States goes toward making ice cream, and America is the number one consumer worldwide. What better way to illustrate the importance of refrigeration technology, than to explore the process of making this country´s favorite frozen treat?

Doug Reindl and Dan Dettmers´ workshop, "I Scream, You Scream, We All Scream for Refrigeration Basics of Ice Cream," is part of the Technical Program at ASHRAE´s 2015 Winter Conference. The Conference takes place Jan. 24-28, Palmer House Hilton, while the ASHRAE co-sponsored AHR Expo is held Jan. 26-28, McCormick Place. Complete Conference information and registration can be found at www.ashrae.org/chicago.

The session explores the process of making ice cream, leads attendees through the cooling load calculations and finishes up with a chance to participate in the ice cream making process.

One catch, however. Attendees have to correctly calculate the cooling load before they can taste the final product, which will be made cryogenically. The workshop starts at 8 a.m. Sunday, Jan. 25.

"We want to reach a younger audience to interest them in the ´R´ in ASHRAE - refrigeration," Reindl, a speaker at the session, said. "We thought this would be an out of the box way to show them about processes, the science, taste and texture of food, home refrigeration."

His presentation will focus on the methods and cooling loads encountered in the ice cream industry.

Session chair Dan Dettmers notes that while ice cream is one of the simple pleasures of life, it also is one of the most complex frozen products available today.

"Unlike ice, which freezes in a crystalline structure, ice cream is an amorphous solid similar to glass," he explained. "Its structure is primarily air held in a complex lattice of sugars and fats. Likewise, the process of producing ice cream is far more complex than most frozen foods with variations from traditional ice cream to frozen novelty bars and cakes."

Other sessions related to refrigeration include:

Energy Use Analysis in Retail and Small/Medium Office Applications, Sunday, Jan. 25

Alternative Refrigerants for Residential Refrigerator-Freezers, Sunday, Jan. 25

Walgreens Pursuit of a Net-Zero Store, Sunday, Jan. 25

ASHRAE PROPOSES EXPANSION OF CLIMATE ZONES FOR STANDAR 90.1 2013

.


http://colombia.ashraechapters.org/DOCS/CIAR_2015.pdfhttp://www.ciar2015.org/home.php



e-NEWSLETTER ATLANTA – New proposed climate data could make the ASHRAE/IES energy standard more applicable for global use.

Addendum w is one of 10 proposed addenda to ANSI/ASHRAE/IES Standard 90.1-2013,Energy Standard for Buildings Except Low-Rise Residential Buildings, open for public comment starting Dec. 5, 2014. The proposed addendum closes for review Jan. 19, 2015. To comment or learn more, visit www.ashrae.org/publicreviews.

The addendum was developed in response to an update of ASHRAE Standard 169-2013,Climatic Data for Building Design Standards, which now contains updated climate data and additional Climate Zone 0 with humid (0A) and dry (0B) zones. Addendum w adds this climate zone to 90.1, This has global implications for the standard as Climate Zone 0 does not exist in the United States and is primarily used in the equatorial regions of South America, Africa, Middle East, southern Asia and the south Pacific.

“It gives the standard more of an international view with maps and data never before available to users,” Dru Crawley, chair of the Standard 169 committee, said. “Previously there was the single U.S. map. Now there are high-level (1 deg latitude/longitude) maps of the world, covering each continent and major countries.”

Other addenda open for public review from Dec. 5, 2014, until Jan. 4, 2015 are:

v revises fenestration orientation requirements

y adds a new approach to simplified building lighting

z clarifies and modifies the modeling of a baseline HVAC system with air source heat pumps and electric auxiliary heat

aa clarifies an exception in a table in the design model section

ad revises the preheat coil requirement for the baseline building model in Appendix G

ae updates a section related to definitions used with motors

af restores the specification of the rating conditioners for measuring efficiency of heat pump pool heaters

ag limits mechanical cooling for vestibules ah clarifies lighting requirements
