Presentation:

The Future of Refrigerants
Safe non-flammable low toxicity F-gases allowed for an exponential increase in the standard of living of society through increased food productivity, reduction in heat related deaths, increased worker productivity and migration of people to cities and to hotter climates.  Refrigerant safety was successfully maintained during the chlorofluorocarbon (CFC) refrigerant transition starting the 1990’s to lower ozone depleting refrigerants with the development hydrochlorofluorocarbons (HCFC’s) and hydrofluorocarbons (HFC’s) chemistries.  The orderly transition from CFCs to HCFCs and HFCs achieved a balance between the societal environmental demands for reduced ozone depletion while continuing to improve the standard of living in developing countries and minimize the societal safety impacts for everyone.

New societal environmental demands to control climate change are driving the development of new regulatory policies to restrict and lower the direct GWP (global warming potential) impact of F-gases.  These regulatory activities have driven significant refrigerant technology development activities globally as a result of climate change concerns.  Today designers are being asked to consider new lower direct GWP unsaturated hydrofluorocarbons (HFOs) refrigerants, some of which are slightly flammable under certain conditions, as well as revisiting the application of natural refrigerants, like carbon dioxide, ammonia, hydrocarbons and water.  This presentation will cover a brief history of refrigerants, how much refrigerants contribute to global warming, update the current regulatory situation, how to name and explain the new ASHARE 2L flammable classification and discuss the future challenges with the new refrigerants.  Insights will be shared into the impact on safety and other design considerations with the various refrigerants being proposed by application.

Tom Lawrence, Ph.D., P.E.
ASHRAE DL
University of Georgia

Session #1 – ASHRAE Standard 189.1 and the International Green Construction Code

ASHRAE, in conjunction with the U.S. Green Building Council and the Illumination Engineers Society, developed Standard 189.1 for the Design of High Performance Green Buildings with the initial release occurring in 2010.  The Standard provides the minimum requirements for a high-performance green building, and was developed with the intent to provide a balance of environmental factors involved with designing, building, and planning for the operation of buildings.  Since the initial release, the Standard has continually evolved as a result of changes in the industry and in relation to other Standards such as 90.1 This session provides a detailed summary of the key changes that are being incorporated in the release of the 2017 version of Standard 189.1 and how this Standard will relate to the International Green Construction Code with the 2018 code cycles revisions.

Session #2 – CO2 Monitoring for Outdoor Airflow and Demand-Controlled Ventilation

A number of programs and standards that exist for buildings today specify the use of outdoor air monitoring.  Monitoring is to be done either based on CO2 levels in the occupied space or actual measurement of outdoor airflow, depending on the space design occupancy and ventilation type (mechanical or natural).  Current standards or program descriptions do not provide detailed guidance for determining what level of CO2 should be considered the maximum concentration to expect, and those that do provide guidance are generally based on a single value above the ambient concentration.  This session describes how to determine a level for CO2 concentrations for an outdoor airflow monitoring program or as part of the upper control limit for a demand-controlled ventilation system.

Session #3 – Thermal Comfort as Related to Energy Consumption: What is the Balance?

Maintaining thermal comfort within an occupied building requires energy, thus optimized solution methods for balancing energy use with indoor environmental quality (adequate thermal comfort, lighting, etc.) are needed. Current building temperature control systems do not adequately take in account the adaptive capability of the occupants, but this concept can be used advantageously during implementation of demand response. Demand response programs commonly include temporary adjustments to space temperature set points and thus can affect the occupants’ thermal comfort perceptions. How to balance out the overall energy consumption and peak demand for cooling or heating within buildings with the need for maintaining adequate thermal comfort in the built environment is an issue important to system designers, building operators and society as a whole. This session provides an overview of the historical development of thermal comfort perception, the two primary approaches used to predict and evaluate thermal comfort, and how these are incorporated in ASHRAE Standard 55. Also covered is a discussion of how thermal comfort considerations can be factored into demand response measures, addressing the conflicting balance between energy consumption and thermal comfort, and a vision on how to possibly achieve an overall optimized balance.

Each Session is worth 1 PDH.

2019 February Chapter Meeting – Refrigeration Tour

When

Tuesday February 12, 2019
• 5:30 – Hy-Vee Commissary Facility Tour
• 6:30 – ASHRAE Dinner & Chapter Meeting at Jethro’s Lake House

Location

Hy-Vee Commissary Facility
4500 SE Delaware
Ankeny, IA 50021
MAP

See link Map for entrance & parking.   Enter at the NE corner straight across from Mills Fleet Farm. Turn west at the fleet farm stop light.

Tour

Every tour attendee must pre-register.  Facility security needs everyone’s name, in order to go on the tour.  If anyone attends that has not pre-registered, they will need a photo ID and will have to check in at the guard shack.

Description:

Tour is of Hy-Vee’s ready to eat food production facility used to support their retail operation.

Refrigeration System:

The ammonia system is a central single stage system.  There currently is one suction pressure with provisions in place for the future addition of a second lower suction pressure.  There are (3) ammonia screw compressors with each having a capacity of 430TR at design conditions.  There are (2) evaporative condensers with each having a capacity of 8,931,000 BTUH of heat rejection.  The ammonia is pumped to the equipment in the facility by ammonia pumps connected to the HT Recirculator Vessel.  All the ceiling hung evaporators in the refrigerated space utilize recirculated liquid ammonia and hot gas defrost with the exception of the +55F Rooms which utilize direct expansion and air defrost.  There are (5) Critical Process Make-up Air Units located on the roof that serve the production areas.  The unit serving the HMR Production Room has a dessicant section designed to aid in the dehumidification of the room.  The -10F Freezers are served by R448a split systems due to there currently not being enough load to justify the installation of a low pressure ammonia system to service this area.  There is a central computerized control system that provides control and monitoring of all the refrigeration equipment.

Steam – (2) 40 HP horizontal firetube steam boilers. The boilers have an operating pressure of 120 psig. The boilers have (1) blowdown separator and (1) chemical feed system. The boilers serve kitchen equipment (including Wok, Brat Pan, Kettle, Flame Grill, etc.)

Hot Water – (2) 200 GPM gas fired water heaters with a 3,000 gallon hot water storage tank. The water heaters serve approximately (50) hose stations for sanitization and other hot water needs throughout the facility (sinks, restrooms, breakrooms, etc.).

Compressed Air – (2) 292 SCFM Oil Free air compressors. The air compressors have an operating pressure of 125 psig. There are (2) desiccant air dryers and (2) 1550 gallon air receiver tanks. The air compressors serve approximately (50) hose stations for sanitization and other process equipment.

Misc HVAC – Other than the refrigeration, the rest of the facility is served by roof top units, make-up air units, split systems and gas-fired unit heaters. The facility has (5) kitchen hoods in the HMR & R&D Kitchens.
