Abstract: Methods and systems for operating a transport climate control system providing climate control within a climate controlled space of a transport unit, the method including setting a mean kinetic temperature setpoint to control a compressor and/or fans in the transport climate control system and determining a mean kinetic temperature in the climate controlled space. The method further includes regulating the mean kinetic temperature in the climate controlled space while optimizing the energy spent by adjusting the cooling and/or heating capacity of the system.

Abstract: There is disclosed a refrigeration system comprising a refrigeration circuit that includes a compressor, a condenser, an expansion valve and an evaporator. A condenser fan of the refrigeration system is configured to operate, under the control of a controller, at a condenser fan speed that is set based on a current refrigeration demand on the system.

Abstract: A transport refrigeration unit and a method for controlling the transport refrigeration unit, wherein the transport refrigeration unit has a controller device for operating a compressor of the transport refrigeration unit with a continuously-variable speed, which allows the compressor to run continuously but with a smooth gradient range of speed variations. The controller device allows the transport refrigeration unit to have a start-stop operation stage, continuous run operation stage, and/or a cycle-sentry operation stage.

Abstract: Methods and systems for controlling a transport refrigeration system are provided. In one instance, the method includes identifying an operational mode change request for a heat exchanger unit of the transport refrigeration system. The method also includes preparing the transport refrigeration system for the operational mode change of the heat exchanger unit, wherein preparing the transport refrigeration system for the operational mode change of the heat exchanger unit includes performing a load control action, the load control action preventing a power source of the transport refrigeration system from at least one of operating outside of a predefined revolutions per minute (RPM) bandwidth and exceeding a predefined power limit of the power source. Also, the method includes changing the operational mode of the heat exchanger unit; and removing the load control action.

Abstract: Methods and systems for coordinated zone operation of the MTRS are provided. The method includes a MTRS controller determining whether a first zone environmental condition difference between a first zone measured environmental condition and a first zone desired set point environmental condition is greater than a first threshold. The method also includes the MTRS controller coordinating operation of the first environmental condition unit and the second environmental condition unit when the first zone environmental condition difference is determined to be greater than the first threshold.
