Abstract
Systems, devices and methods provide energy recover, modular systems to build and revise commercial kitchen services, closed circuit exhaust, and high efficiency capture and containment of fumes from cooking processes.
Claims5
A method of conveying heat energy, comprising:
- flowing exhaust fumes from an exhaust hood through a heat exchanger;
- using a liquid conveyed through the heat exchanger as a heat source for a heat pump to generate heat at a higher temperature than the liquid;
- using the heat exchanger to collect grease by capturing grease on heat transfer surfaces of the heat exchanger;
- and
- periodically reversing the heat pump to melt grease from the heat transfer surfaces.
