Abstract

An energy storage device for providing electrical energy to a refrigeration unit arranged to cool a container, the refrigeration unit including a condenser and an evaporator configured to cool air entering the container, the energy storage device including a casing; a battery disposed in the casing; and an evaporator subsystem including: a supply refrigerant tube configured to supply refrigerant from downstream of the condenser of the refrigeration unit; an expansion device arranged to receive condensed refrigerant from the supply refrigerant tube; a heat exchanger arranged to receive and evaporate refrigerant from the expansion device; a return refrigerant tube configured to return refrigerant from the heat exchanger to downstream of the evaporator of the refrigeration unit; wherein the evaporator subsystem includes an evaporator fan assembly constructed and arranged to flow air through the heat exchanger and into the casing about the battery.

First claim

What is claimed is:

1. A energy storage device for providing electrical energy to a refrigeration unit arranged to cool a container, the refrigeration unit including a condenser and an evaporator configured to cool air entering the container, the energy storage device comprising:
a casing;
a battery disposed in the casing; and
an evaporator subsystem including:
a supply refrigerant tube configured to supply refrigerant from downstream of the condenser of the refrigeration unit;
an expansion device arranged to receive condensed refrigerant from the supply refrigerant tube;
a heat exchanger arranged to receive and evaporate refrigerant from the expansion device;
a return refrigerant tube configured to return refrigerant from the heat exchanger to downstream of the evaporator of the refrigeration unit;
wherein the evaporator subsystem includes an evaporator fan assembly constructed and arranged to flow air through the heat exchanger and into the casing about the battery.

2. The energy storage device set forth in claim 1 , further comprising:
a housing adapted to enclose the casing and the evaporator subsystem, wherein the housing is thermally insulated.

3. A energy storage device for providing electrical energy to a refrigeration unit arranged to cool a container, the refrigeration unit including a condenser and an evaporator configured to cool air entering the container, the energy storage device comprising:
a casing;
a battery disposed in the casing; and
an evaporator subsystem including:
a supply refrigerant tube configured to supply refrigerant from downstream of the condenser of the refrigeration unit;
an expansion device arranged to receive condensed refrigerant from the supply refrigerant tube;
a heat exchanger arranged to receive and evaporate refrigerant from the expansion device;
a return refrigerant tube configured to return refrigerant from the heat exchanger to downstream of the evaporator of the refrigeration unit;
wherein the heat exchanger is a tube wrapped about, and in direct contact with, the casing for conductive heat transfer.
