摘要： A method of operating a refrigeration system (20) includes operating the refrigeration system in refrigeration mode. A current access condition into a refrigerated cargo space (22) is detected. At least one heat exchanger (32) in the refrigerated cargo space (22) is directed into a defrost mode during the current access condition. The refrigeration system (20) is directed into a refrigeration mode when the current access condition is no longer detected.

摘要： A method of operating a transport refrigeration system comprises: controlling, using a controller (30), a plurality of components of the refrigeration system and monitoring, using the controller, a plurality of operating parameters of the refrigeration system. The controlling comprises operating at least one of a prime mover (26), heater (48), and electric generation device (24). The operating parameters comprise at least one of a speed of the prime mover and a voltage of the electric generation device. The method comprises detecting, using the controller, when at least one of a heating mode and a defrost mode is required; activating, using the controller, the heater when at least one of the heating mode and the defrost mode is required; comparing, using the controller, the voltage of the electric generation device to a selected voltage; and controlling, using the controller, the speed of the prime mover in response to the voltage of the electric generation device.

摘要： A method of operating a refrigeration system. The method includes operating a multi-temperature refrigeration system that has a plurality of heat absorption heat exchangers in a single temperature mode. A number of the plurality of heat absorption heat exchangers are determined that require defrosting a single heat absorption heat exchanger is directed into a different operational state when the number of heat absorption heat exchangers that require defrosting is equal to one. E of the plurality of heat absorption heat exchangers is directed into a defrost mode when the number of heat absorption heat exchangers that requires defrosting is more than one.
