Energy storage systems utilizing compressed air and associated systems and methods

An elastocaloric heat pump, comprising:

• a channel extending between a first reservoir and a second reservoir;
• and
• a plurality of shape-memory alloy wires extending from an interior surface of the channel, wherein—
• when the elastocaloric heat pump is in a heating state, the shape-memory alloy wires are configured to release heat to fluid flowing through the channel, and
• when the elastocaloric heat pump is in a cooling state, the shape-memory alloy wires are configured to absorb heat from the fluid flowing through the channel.

A radiant panel system, comprising:

• a radiant panel;
• a valve fluidly coupled to the radiant panel, a hot air line, and a cold air line, the valve including:
• a selector component configured to select or proportion between airflow from the hot air line and airflow from the cold air line;
• and
• a pulsing component configured to pulse the selected or proportioned airflow into the radiant panel;
• and
• a controller operably coupled to the valve.

A compressed air electrical device, comprising:

• an air reservoir configured to store compressed air;
• a valve fluidly coupled to the air reservoir;
• a compressed air utilization component operably coupled to the valve;
• a piezoelectric element operably coupled to the compressed air utilization component;
• a capacitor electrically coupled to the piezoelectric element;
• and
• an electrical component electrically coupled to the capacitor.
