Abstract
In one aspect, a pump-motor assembly is provided outside of and adjacent to a storage container that stores a back-up energy storage unit. The pump-motor assembly includes a pump-motor that maintains a minimum pressure of a liquid coolant in a liquid coolant system that cools the back-up energy storage unit, and a housing that is completely enclosed, the housing containing the pump-motor, and having a removable access panel on one side thereof the enclosed structure, and an opening on another side thereof to the storage container.
Claims20
A pump-motor assembly provided outside of and adjacent to a storage container that stores a back-up energy storage unit, the pump-motor assembly comprising:
- a pump-motor that maintains a minimum pressure of a liquid coolant in a liquid coolant system that cools the back-up energy storage unit;
- and
- a housing that is completely enclosed, the housing containing the pump-motor, and having a removable access panel on one side thereof the enclosed structure, and an opening on another side thereof to the storage container.
The pump-motor assembly of claim 2, wherein the housing is configured to receive air cooled by a heating, ventilation, and air conditioning (HVAC) unit in the storage container through the opening to the storage container.
An energy storage system, comprising:
- a storage container that stores a back-up energy storage unit, including one or more energy sources;
- a heating, ventilation, and air conditioning (HVAC) unit provided in the storage container to cool air in the storage container;
- a liquid cooling system that cools the back-up energy storage unit;
- and
- a pump-motor assembly provided outside of the storage container, the pump-motor assembly comprising:
- a pump-motor that circulates a liquid coolant in the liquid coolant system at a minimum pressure;
- and
- a housing that is completely enclosed, the housing containing the pump-motor, and having an opening on one side thereof that connects to an opening in the storage container.
An energy storage system, comprising:
- a back-up energy storage unit, including one or more energy sources;
- a storage container that stores the back-up energy storage unit;
- a heating, ventilation, and air conditioning (HVAC) unit that cools air in the storage container;
- a liquid cooling system that cools the one or more energy sources of the back-up energy storage unit;
- a pump-motor provided outside of the storage container, the pump-motor assembly being connected to the liquid cooling system and maintaining a minimum pressure of a liquid coolant in the liquid coolant system;
- and
- a housing containing the pump-motor, the housing being sealed from ambient air, and having a removable access panel on one side thereof the enclosed structure, and an opening on another side thereof that connects to an opening in the storage container, wherein cool air from the storage container flows into the housing, and hot air from the housing flows into the storage container.
