BBJ Environmental Solutions (OTCBB:BBJE) is pleased to announce its sponsorship of a groundbreaking study by the School of Mechanical and Aerospace Engineering at Oklahoma State University in Stillwater, Oklahoma. The first phase of the study entitled Design of a Portable Test Rig for Testing Terminal Air Conditioners, was completed in early December by the Senior Design Projects Class. This phase consisted of designing and building a test apparatus that will accurately capture and record the operating parameters of a Packaged Terminal Air Conditioner (PTAC) unit. These units are used widely in apartments, hotels, classrooms and like facilities to provide individually controllable heating and air-conditioning and are huge consumers of electrical power throughout the world.

Project Leader Trapper Wilson stated that this has been a challenging project. This is in part because accurate air flow measurements require long duct runs with established air flow and PTAC units discharge air directly from the fan housing. The team had to design and validate a 'virtual duct' in order to obtain accurate measurements within the available space.

In this time of looming energy shortages, the efficiency and power consumption of air conditioning systems is a pressing concern. Although it is generally believed that clean, well-maintained units operate more efficiently and thus conserve energy, this has not been previously studied and the degree of savings possible has not been documented. This test apparatus will capture power use, airflow, temperatures and relative humidity. The resulting data set will then be used to calculate cooling and heating output compared to power usage.

Dr. Dan Fisher, the OSU Professor supervising the project commented that this is an exciting project. He noted that the next step is for the Team to proceed to use the apparatus to capture data on units in a hotel in Clearwater, Florida. He expects that this phase will be completed in January 2002. The units will then be cleaned using best industry practice by the Clearwater based unit of the internationally known Ductbusters HVAC Cleaning organization. All cleaning will be done using BBJ's revolutionary new coil cleaning product, BBJ Power Coil Clean(TM). Following cleaning, additional measurements will be taken to document the operational parameters. The team will then be able to determine the change in operating efficiency. The resulting data will allow building owners to evaluate the energy savings available from different levels of maintenance in order to better plan their maintenance programs. The team should be in a position to publish data from these tests in early 2002. Depending on what we learn from the first data set, we may plan additional studies using this apparatus.
