Abstract
A method of warming a valve assembly includes receiving an exhaust flow through a first heat exchanger first inlet; heating a coolant received through a first heat exchanger second inlet with the exhaust flow; exhausting the exhaust flow through a first heat exchanger first outlet; and discharging heated coolant through a first heat exchanger second outlet towards a second heat exchanger assembly that is coupled to the valve assembly to heat the valve assembly.
Claims17
A vehicle, comprising:
- a first exhaust muffler arranged to receive a first exhaust flow from a first engine;
- a transport refrigeration unit (TRU) arranged to condition an interior of a compartment of the vehicle, comprising:
- a second exhaust muffler arranged to receive a second exhaust flow from a second engine associated with the TRU;
- and
- a fluid circuit, comprising:
- a first heat exchanger having a first heat exchanger first inlet arranged to receive at least one of the first exhaust flow and the second exhaust flow, a first heat exchanger second inlet arranged to receive a coolant, a first heat exchanger first outlet arranged to release at least one of the first exhaust flow and the second exhaust flow, and a first heat exchanger second outlet, and
- a valve assembly coupled to a second heat exchanger having a second heat exchanger first inlet arranged to receive the coolant from the first heat exchanger second outlet, a second heat exchanger second inlet arranged to receive gas from a gas tank supported on a vehicle body for storing gas for use in at least one of the first engine and the second engine, a second heat exchanger first outlet fluidly connected to the first heat exchanger second inlet, and a second heat exchanger second outlet arranged to direct gas to the TRU.

A fluid circuit provided with trucking vehicle having a transport refrigeration unit, comprising:
- a first heat exchanger arranged as a dual flow heat exchanger that is arranged to receive an exhaust flow from an engine through an exhaust muffler to heat a coolant received from a second heat exchanger;
- a valve assembly coupled to the second heat exchanger that is arranged receive the coolant to heat the gas received from a gas tank and provide the gas to the transport refrigeration unit;
- and
- a fluid pump arranged to facilitate a fluid flow of the coolant from the first heat exchanger to the second heat exchanger.
