The controller includes: a load calculation unit that calculates an air conditioning load of the air conditioner; a charge calculation unit that calculates a usage charge based on the air conditioning load; and a charge display unit that displays the usage charge on the charge display device.

An air-conditioning system includes: an air conditioner mounted on a mobile body having a cold storage; an internal temperature sensor configured to measure an internal temperature inside the cold storage; a notification device configured to notify an error of the air conditioner; and a control unit configured to control an air-conditioning operation. The control unit includes an acquisition unit configured to acquire the internal temperature, a setting unit configured to set an appropriate temperature range of the cold storage, a determination unit configured to determine whether the internal temperature is within the appropriate temperature range, and a notification control unit configured to control an error notification using the notification device and perform a temperature error notification when the internal temperature is out of the appropriate temperature range after a pre-cooling by the air conditioner is completed, and does not perform the temperature error notification before the pre-cooling is completed.

A transport climate control system for providing climate control to a climate controlled space of a transport unit. The transport climate control circuit includes a compressor, an evaporator and at least two fans. The transport climate control circuit also includes a controller for controlling the transport climate control circuit and for defrosting the evaporator coil. When a defrost event is triggered, the controller instructs the transport climate control circuit to supply heat to or around one section of the evaporator coil, and independently controls each of the at least two fans to move the air around the evaporator coil in a controlled direction so that heat from the one section of the evaporator coil is used to convectively heat the inlet of the evaporator coil.

A system for managing ripeness of perishable goods including: a storage device to store perishable good requirements, ripening capability parameters, ripening schedules, and perishable good parameters associated with the perishable goods; and a ripeness management system coupled to the storage device. The ripeness management system including: a current ripeness determination module to determine current ripeness levels in response to at least one of the perishable good parameters, the perishable good requirements, and the ripening schedules; a ripeness schedule module to determine predicted ripeness levels in response to at least one of the current ripeness levels, the ripening capability parameters, and the ripening schedules; and a meshing module to determine ripening schedule adjustments in response to at least one of the current ripeness levels, the perishable good parameters, the ripening schedules, and the ripening capability parameters.

A refrigerated compartment and refrigerated vehicle with dynamic control of a temperature field, including a compartment body. A refrigeration mechanism is fixed on a compartment body side wall and injects cold air into the compartment body. Steering mechanisms are fixed on the top wall of the compartment body, and each is connected with a fan. The fan accelerates the flowing cold air and the steering mechanism drives the fan to rotate and the change the cold air flow direction. Temperature sensors are equipped with the compartment body side walls and can detect the temperature. The temperature sensors are connected to a control mechanism arranged outside the compartment body and transmit detected information thereto. The control mechanism is connected to the steering mechanism, fan, and refrigeration mechanism through the speed regulator. The control mechanism controls the refrigeration mechanism working power and the operation of the steering mechanism and the fan.
