The U.S. Army Engineer Research and Development Center (ERDC) Cold Regions Research and Engineering Laboratory (CRREL) invites solutions that will enhance the Frost Effects Research Facility (FERF) cooling reliability and efficiency. Solutions need to allow for lower temperatures to be sustained and controlled inside the research space of the FERF.
Located in Hanover, NH, the FERF is the largest refrigerated warehouse in the United States that can be used year-round for a variety of roadway and pavement, geotechnical, and other investigations at sub-freezing temperatures. Tests can be conducted using a combination of ambient and ground temperatures from approximately 20°F to 80(+)°F, with the ability to conduct accelerated pavements testing and evaluation due to the effects of repeated freezing and thawing.
On-hand equipment to support non-destructive pavements investigations includes a 20-ton crane on a rail, a falling weight deflectometer (FWD), a heavy weight deflectometer (HWD), a heavy vehicle load cart to rapidly replicate a large number of passes by typical highway traffic loads, and other equipment.
In addition to controlling temperatures, testing can incorporate controlled moisture conditions and use a variety of specific sub-grade materials.
As an example of the FERF’s flexibility to accommodate a wide range of RDT&E investigations, a mobile 40-ft wave tank is housed in the Southeast quadrant to study sea-ice interactions with waves and petroleum products, with wider temperature ranges and other additional testing capabilities. The facility will soon become home to a Frost Effects Load Simulator to simulate dynamic loading on a wide array of infrastructure at sub-freezing temperatures.
The ERDC-CRREL is interested in solutions that entail the development of a system, or components of a system, that will be able to cool the FERF and better utilize and control the existing cooling system. There are thought to be many potential solutions that can be utilized to accomplish this.
For informational purposes only, the current state of the FERF includes the following conditions:
- The FERF has twelve (12) air handlers, three (3) of which are at end of life.
- The FERF has spaces for two (2) additional air handlers.
- The air handlers utilize electric defrost that tax the electrical system and add heat to the space.
- The switchgear is at end of life and there are no available breaker buckets.
- The FERF has three (3) new chillers (one (1) low and two (2) medium temperature); currently only the medium temperature chillers service the building. There is no valving to utilize the low temperature system in the FERF.
- The warm glycol defrost system is not operational.
- Many of the valves in the FERF are air operated and currently uncontrollable.
- The building envelope has some gaps that let heat in.

Background and Problem Statement
The FERF is a prototype large scale research facility with approximately 29,000 SF, of which approximately 20,000 SF is cooled research space. The FERF cooling system utilizes two (2) cold glycol tanks (one (1) low-temperature and one (1) medium-temperature) that are cooled by three (3) chillers (two (2) medium-temperature specified to produce glycol between -15°F to 120°F and one (1) low-temperature specified to produce glycol between -37°F and 50°F) and one (1) tank that stores warm glycol. The heat pumps that previously produced the warm glycol are inoperable. The 60/40 ethylene glycol refrigerant in the medium temperature tank is then circulated through a series of air handling units (AHU) to cool the FERF space. The tanks and medium-temperature chillers can produce about 120 tons of cooling. The currently functional AHU’s can produce approximately 70 tons of cooling. Solutions need to enhance the cooling capabilities, controls, and efficiencies of the FERF.
Desired End State
The objective of this effort is to be able to control the FERF to within 3°F, maintain temperatures below 25°F, and produce a total system cooling capacity of 120 tons of refrigeration. The upgraded system should also have the capability of utilizing the warm glycol tank and existing operable infrastructure to defrost the air handlers with warm glycol. Complete or partial solutions will be considered, and multiple awards may result from this announcement.
Submissions will be evaluated based on the criteria described in ERDC’s CSO Solicitation document. Evaluations will be conducted by a project team comprised of nationally recognized government experts.
