System and method of controlling passage of refrigerant through eutectic plates and an evaporator of a refrigeration system for a container of a vehicle
First Claim
1. A system comprising:
- a mode module configured to determine whether to operate in an engine mode or a battery mode based on a plurality of parameters;
an engine module configured to, while operating in the engine mode, (i) run a compressor of a vehicle at a first speed, and (ii) permit passage of refrigerant through eutectic plates independent of a temperature within a temperature controlled container of the vehicle;
a battery module configured to, while operating in the battery mode and based on the temperature within the temperature controlled container of the vehicle, (i) run the compressor at a second speed, and (ii) prevent passage of the refrigerant through the eutectic plates,wherein the second speed is less than or equal to the first speed; and
a control module configured to, while the engine module is operating in the engine mode, have a battery of the vehicle charged using power received from at least one of a first electrical source driven by an engine of the vehicle or a second electrical source driven by a solar panel, wherein the first electrical source is an alternator or a generator, andwherein, while operating in the battery mode, the battery is not being charged from either the first electrical source or a shore power source.

Abstract
A system including mode, engine, and battery modules, where the mode module determines whether to operate in an engine mode or a battery mode based on parameters. The engine module, while operating in the engine mode, runs a compressor at a first speed based on a temperature within a temperature controlled container of a vehicle and permits passage of refrigerant through eutectic plates independent of the temperature. A battery, while in the engine mode, is charged based on power received from an electrical source. The battery module, while operating in the battery mode and based on the temperature, runs the compressor at a second speed and prevents passage of the refrigerant through the eutectic plates. While in the battery mode, the battery is not being charged based on power from a shore power source and the electrical source from which power is received during the engine mode.
