Proposed Rulemaking for Walk-in Coolers and Freezers

Proposed Rulemaking for Walk-in Coolers and Freezers

Since EISA was passed January 1, 2009, the U.S. Department of Energy (DOE) has been working to mandate a standardized energy efficiency test for walk-in coolers and freezers.  The first step was taken with an informal meeting on February 4, 2009 to discuss comments and suggestions from industry professionals on determining a testing procedure. After nearly a year’s worth of research, DOE has published their proposed testing procedure for walk-in coolers and freezers. A follow-up meeting was scheduled to discuss these proposed rulings, but due to winter weather the meeting was cancelled and has not been rescheduled at this time.

In accordance with section 312 of the Energy Independence and Security Act (EISA), DOE published a Notice of Proposed Rulemaking (NOPR) for the test procedure on walk-in coolers and freezers. The NOPR is the first published document for the test procedure rulemaking process for walk-ins. DOE proposes the procedures explained in the NOPR be used to test walk-in equipment. Once performance standards are accepted, manufacturers will be required to use the accepted test to determine compliance and for all representations regarding the energy use of the product.

DOE proposes to adopt a test procedure that contains two separate testing methods; one for the insulated box and the other for the refrigeration equipment. Each of the two components, the insulated box and the refrigeration system, will be tested separately. The manufacturer will be responsible for testing their product respectively and must provide compliance with all testing standards.  Read the rest of this entry »

Walk-in Freezers Used to Heat Water?

At U.S. Cooler, we strive to bring more value to our customers.  One of the ways we accomplish that is by keeping informed on opportunities to improve your bottom line.

Did you know your walk-in coolers and freezers are potentially capable of doing double-duty?  It’s a well kept secret you may wish to consider.  Depending upon your existing (or hopefully new, from U.S. Cooler) equipment, you may be able to save thousands of dollars annually by capturing the heat rejected from air-cooled condensing units and using it to pre-heat hot water.

Retrofitting LED Lights Can Pay Off In Your C-store

As a convenience store owner, if there was a change you could make to increase merchandise sales, lower your electric bill, reduce maintenance costs, and be environmentally responsible would you make the change? The opportunity to do just that is here with the advent of LED Retrofit Kits. These kits replace the existent fluorescent lighting on your glass door merchandising walk-in cooler and freezer with 4’, 5’ or 6’ long LED light strips.

LED lighting provides a 68 to 85% energy savings over the fluorescent lights typically used in coolers and freezers. LED’s use only 15 watts for a 5’ model and 18 watts for 6’. But if energy savings was the only advantage, adoption of LED’s wouldn’t be near where it is today. The real difference is the attractive quality of the light it gives off. LED’s give your products a beckoning glow and more uniform illumination than fluorescent.  You can choose between lights that give off a neutral or slight red or blue hue. Conventional wisdom suggests that the more appealing the product presentation, the more likely a customer is to take notice and purchase it. Read the rest of this entry »

Types of Refrigeration Systems Used in Walk-ins

Refrigeration systems consist of a condensing unit and an evaporation coil. The condensing unit is located outside the walk-in and the evaporator is located inside the walk-in. The compressor compresses gas to a liquid. The liquid is then pumped through the condensing unit coil while a fan blows outside air through the coil. Gas is condensed to a liquid and is then pumped through a small copper pipe into the walk-in to the evaporator coil. There, through the expansion valve located in the evaporator coil the liquid is allowed to expand back into a gas. The expansion of the liquid to a gas causes a rapid chilling of the evaporator coil. Since heat always flows toward cold, inside the walk-in air is blown across the evaporation coil to let the coil absorb heat from inside the walk-in. The gas is then allowed to exit the walk-in through a larger copper pipe to the condensing unit where it is once again compressed and cooled to a liquid state and returned to the evaporator coil inside the walk-in. There the cycle is started over.

The new EISA law requires all new walk-ins be equipped with high efficiency motors to be compliant. These cost a little bit more but save you money in the long run. Some suppliers may try to sell you non EISA compliant refrigeration systems. To be compliant with the law and purchase the best lifetime value always ask for EISA compliant equipment.

1. Remote Systems - Remote systems are the least expensive systems to purchase. They consist of a condensing unit, evaporator unit and misc. parts such as expansion valve, site glass, dryer, pump down solenoid thermostat, and on freezers a timer and drain heater to install the system. They require the use of a licensed refrigeration installer since they are pumped down and charged with refrigerant gas on site. The installer will also charge for any other parts needed for the install such as copper pipe, pipe insulation, connectors, and electrical. They are less expensive systems to buy with the walk-in but may cost more over all depending on what the going hourly rate is with the installer and the cost of the parts he provides. They also provide an advantage by allowing the condensing unit to be located outside the building. There the condensing unit can dump its heat without adding extra heat to the building and air conditioning systems. Read the rest of this entry »

Firehouse Renovation on Illinois Stories

Craig Industries / U.S. Cooler’s corporate offices are located in a renovated firehouse in Quincy, Illinois. Engine House No. 4 was originally built in 1898 and housed two horse-drawn fire wagons. It was used by the fire department until 1940 and has subsequently been used for textile manufacturing. In the Fall of 2008, Craig Industries completed a restoration of the building that was faithful to the original design. The interior features modern amenities but still has a nostalgic feel with the original brick walls and  wooden supports intact.

Engine House No. 4 will be featured on the PBS program Illinois Stories at 6:30pm, December 10th (WSEC – Jacksonville/Springfield, WQEC – Quincy, QMEC – Macomb).

Illinois Stories: From the river heritage of Quincy and Hannibal, to the bounty of the richest farmland on earth, Mark McDonald hosts this Emmy award winning series about the people and places of central and western Illinois. PBS

Food Safety Reform Bill Passes U.S. Senate Panel

WASHINGTON (Reuters) – A U.S. Senate committee voted unanimously on Wednesday to increase government oversight of food safety but the first significant overhaul in 50 years may not happen until 2010.

Pressure to overhaul the food safety system has grown following several high-profile outbreaks involving lettuce, peppers, peanuts and spinach since 2006 that have sickened thousands and killed several.

However, the full Senate probably won’t vote on the bill until 2010 as Congress is currently mired in debate about overhauling the U.S. healthcare system, said Tom Harkin, chairman of the Senate Health, Education, Labor and Pensions Committee.

“I really, honestly, I just don’t see how we’ll get to it before Christmas,” Harkin said of the food safety bill.

The Senate bill would expand U.S. Food and Drug Administration (FDA) oversight of the food supply and shift its focus toward preventing, rather than reacting, to foodborne outbreaks. FDA would have the power to order recalls, increase inspection rates and require all facilities to have a food safety plan. Read the rest of this entry »
