SYSTEMS AND METHODS FOR TEMPERATURE CONTROL IN REFRIGERATION SYSTEMS AND HEATING SYSTEMS

The present invention provides systems and methods for temperature control in refrigeration systems, such as beverage coolers, and heating systems, such as coffee dispensers. In an embodiment of the present invention, a control unit of a refrigeration system in accordance with the present invention receives and records activity data such as door openings and/or human presence detection in the vicinity of the refrigeration system, and then establishes the beginning and end times of an energy saving mode for the refrigeration system over a period of time, such as a week. The control unit calculates the time to restart the compressor cycle at the end of the energy saving mode so that the product will be at the correct temperature at the time of first usage. As part of the energy saving function, the lamps and fans in the refrigeration system are controlled independently by the control unit according to the activity data.
