Help Reduce Energy Costs by Recovering Heat From Industrial Refrigeration Systems

Mike Nielsen | Global Application Team Leader, Vilter

Emerson’s Commercial and Residential Solution’s Business

Heat recovery from industrial refrigeration can be an effective way for facilities to help reduce power consumption and energy costs.

Depending on a system’s setup, the heat produced from a basic screw compressor refrigeration system can be used elsewhere. How it’s recovered and redirected depends on the industry and/or application. Among the most common heat recovery applications is to heat water for purposes unrelated to refrigeration such as wash-down and cleanup in a cold storage processing facility.

Not only can compressor heat recovery help to reduce the amount of energy used to heat water elsewhere in a facility, but it also can contribute to reduced water usage when a system doesn’t have to heat as much water. This is especially relevant in areas where water costs are higher. Every system and installation is different, so it’s important to evaluate whether the potential for reduced energy consumption and costs outweigh the investment in equipment to reuse compressor heat.

Integrating water systems

Under standard operation conditions, industrial refrigeration systems produce condenser heat, super-heated vapor heat, and oil heat. There are multiple ways to integrate these refrigeration systems with a typically separate water system to employ a heat recovery strategy, but some extra equipment may be needed.

The first step is to determine the facility’s hot water requirements and whether refrigeration compressor heat can be utilized in the hot water system. In both new and existing refrigeration systems, the equipment would have to be designed for this expansion.

For instance, some type of water system would be needed, as would a storage tank and a pump to bring in water. Then, the water would need to be pumped out to the heat source and returned to the hot water storage tank.

Consider full energy cost impact

Even though more heat can be generated by elevating the refrigeration system parameters, it’s important to consider how important energy recovery is to your overall operational goals.

Raising the condensing temperature can increase discharge water temperatures. As a result, more energy can go into the compressor, so it’s important to make sure the energy recovered for heating water is worthwhile. In some regions where electricity costs more than natural gas or propane, this approach may not be a good option. In other areas where electricity costs are relatively low and the cost for natural gas or propane is the same or higher than electricity, it might make sense to generate more heat with the compressor.

Many existing systems can be retrofitted to recover refrigeration compressor heat. This can be a bigger undertaking than a new system; re-piping, new equipment or a change in condenser type and heat exchangers can be required. But the investment may be worth the effort if a facility is experiencing high energy costs.

Enabling efficiency and energy savings

Recovering heat from refrigerator compressor systems to heat water for other processes can enable facilities to reduce overall energy costs. Highly efficient equipment such as Vilter™ single-screw compressors are designed to help provide lower lifecycle costs and high reliability. They also can enable facilities to reduce the energy consumed in the refrigeration system while lowering the energy needed to heat the water within those facilities.

150 Years of Innovation at Vilter

AntonioDeLourdes Antonio De Lourdes | Research & Development Lead Engineer, Vilter

Emerson Commercial & Residential Solutions

This year Vilter Manufacturing celebrates 150 years! The company’s rich history tells a story of perseverance and drive to cultivate continuous innovation within the industrial refrigeration and gas compression industries.

2016 Facebook post_1200x717_Vilter150

HISTORY

  • 1867: Vilter Manufacturing starts as a general jobbing shop that Peter Weisel opened in 1867 in Milwaukee, WI
  • 1880: Ernest Vilter became a partner in the business and soon after introduced the Corliss Engine (1880) and the first Refrigeration Compressor (1882)

After surviving a devastating fire that burned the entire factory down (1892), Vilter focused on rebuilding on a larger site. Landing on their feet, Vilter quickly rose as an industry leader in providing cooling equipment to ice plants, breweries, and packing houses. Vilter even played a crucial role in supporting the United States in World War I and World War II.

 TODAY

To accommodate growing sales, Vilter moved to its current location in Cudahy, WI in 1999. Many changes took place over the next 18 years, including being acquired by Emerson in 2009. Here are several recent innovations:

  • 2005: Began manufacturing high-pressure single screw compressors.
  • 2007: Released Viltech, a more robust controller for reciprocal compressors
  • 2010: Named the official sponsor of the U.S. Bobsled and Skeleton teams for the 2010 Winter Olympics held in Vancouver. Also developed in 2010, were the Vission, Vantage and Vission 20/20 controllers.
  • 2012: Built a 7,000-pound Ammonia test lab
  • 2013: Developed the 401 mm line, the largest single screw compressor
  • 2015: Developed a 50 TR CO2 subcritical compressor, a high suction pressure solution that could handle 750 PSI of suction pressure
  • 2016: Released the VSMC product line

FUTURE

 While continuing to address total cost of ownership (equipment cost, maintenance costs, and energy costs), end-users are now evaluating solutions to lower the charge of ammonia systems and/or completely removing the ammonia out of the occupied spaces. Vilter is developing robust, efficient solutions that meet customer needs:

  • Systems utilizing CO2 as a volatile secondary fluid
  • Cascade systems using CO2 in the low stage
  • Booster transcritical CO2 systems

Vilter is also capturing the voice of the customer by utilizing Virtual Reality (VR). Virtual reality allows customers to visualize the end product early in the design process. This gives customers an opportunity to provide feedback to create designs to fit their requests.

Dedicated to excellence, Vilter continues to innovate and adapt to meet the needs of their industries. Vilter and Emerson look forward with confidence to the next 150 years.

Emerson at IIAR

Technical experts from Vilter Manufacturing LLC, a business of Emerson Climate Technologies, will be heading out to Colorado Springs this week to present the latest information about next generation ammonia heat pumps.  Vilter will also sponsor a Regulatory and Code Update Lunch during the International Institute of Ammonia Refrigeration’s (IIAR) 2013 Industrial Refrigeration Conference and Exhibition. The technical presenters from Vilter will be available before and after each presentation in booths #518-522.

Globally, the food and beverage industry’s need for energy efficiency and water savings is growing. More than 90percent of the energy consumed for refrigeration is wasted as heat rejected into the atmosphere. However, industrial heat pumps can capture that wasted heat and significantly lower a plant’s energy and water consumption. Installing heat pumps to capture waste heat from industrial processes is increasingly popular in Europe, largely because the heat they deliver far exceeds the energy they consume, greatly reducing the reliance on fossil fuels. Attendees will discover how the design and operation of food and beverage processing plants of the future will be adapted to capitalize on the benefits of industrial heat pumps.

The IIAR conference is an exceptional educational and networking forum for the industrial refrigeration industry.  We are honored to share our experiences and the knowledge we’ve acquired with our peers. More information about IIAR can be found at www.iiar.org

Have you attended IIAR in the past? If so, we would be interested in knowing your thoughts about IIAR in general, and heat pump technology in particular, especially as it relates to utilizing ammonia as the primary refrigerant.
