Abstract: A system using waste heat of a refrigeration unit to heat a food product, having a heating loop connected to a refrigeration unit between the compressor and the condenser, and configured to allow refrigerant to enter the heating loop to transfer heat to a food product.

Abstract: An apparatus, method, and computer program for process control using people and asset tracking information are provided. One or more process control data elements are received, which define a location associated with a person and/or an asset in a processing environment. At least part of the processing environment is controlled using the one or more process control data elements. For example, the processing environment could be controlled based on whether a specified area has been evacuated or whether one or more specified personnel or types of personnel are present in the specified area. The location can also be used to prevent the person and/or the asset from entering a restricted part of the processing environment, identify any people failing to reach specified zones of the processing environment during an incident, and identify a current actual or estimated location of at least one person to be rescued in the processing environment.

Abstract: An apparatus, method, and computer program for integrating people and asset tracking information into a process control system are provided. Location information associated with a person and/or an asset in a processing environment is received. The location information is converted into one or more process control data elements. The one or more process control data elements are provided to at least one process control solution. The at least one process control solution is operable to control at least part of the processing environment using the one or more process control data elements. The location information could include text strings, and the one or more process control data elements could include Object Linking and Embedding (OLE) for Process Control (OPC) parameters and/or System Control and Data Acquisition (SCADA) data points.
