Systems and methods for providing power to a refrigeration unit or an air conditioner used on a hybrid vehicle. The system includes an accumulation choke, a PWM rectifier, and a frequency inverter. The accumulation choke is configured to receive a first AC power, a second AC power, and a DC power. The accumulation choke and PWM rectifier convert the received power into an intermediate DC power having a peak voltage. The PWM rectifier provides the intermediate DC power to the frequency inverter. The frequency inverter converts the intermediate DC power to an output AC power. The frequency inverter provides the output AC power to the refrigeration unit.

A transport refrigeration unit (TRU) includes a compressor. The TRU further includes a condenser disposed downstream of the compressor. The TRU further includes an expansion device disposed downstream of the condenser. The TRU further includes a first flow control device disposed downstream of the condenser. The TRU further includes a first evaporator disposed downstream of the expansion device and the first flow control device. The first evaporator is disposed upstream of a second flow control device. The second evaporator is disposed downstream of the first flow control device, the expansion device, and the second flow control device. The second evaporator includes a thermal accumulator. The second flow control device disposed upstream of the compressor.

A temperature control system having an increased heating performance. The system includes a compressor adapted to compress a fluid, a heat exchanger coupled to the compressor such that compressed fluid moves from the compressor to the heat exchanger, and a pressure regulating valve positioned between the compressor and the heat exchanger such that compressed fluid from the compressor moves through the valve before reaching the heat exchanger. The pressure-regulating valve is designed to stay in a closed position until the pressure of the fluid from the compressor reaches a desired value. By virtue of this design, the pressure of the fluid in increased, thus resulting in an increased in the temperature of the fluid. Upon reaching the desired pressure, the valve opens to allow the highly-pressurized fluid to flow to the heat exchanger.
