Integrated energy recovery base or roof-curb for air-conditioning unit

An energy recovery device comprising:

• an HVAC unit positioned and mounted on a top of a support housing, the support housing defining an airtight plenum;
• an energy recovery core mounted within the airtight plenum, the energy recovery core operable to transfer heat and moisture between a flow of outside air and a flow of exhaust air;
• a divider within the airtight plenum separating the airtight plenum into a first side containing the energy recovery core, and a second open side isolated from the first side;
• wherein the energy recovery core is mounted to the airtight plenum;
• the energy recovery core and airtight plenum defining four isolated sections to receive air flows across the energy recovery core;
• the airtight plenum defining a first opening in communication with a first of the four isolated sections to receive an outside air flow, outside air flow proceeds through the energy recovery core to a second of the four isolated sections which exits the airtight plenum through a second opening directly to the HVAC unit;
• the airtight plenum defines a third opening in communication with a third of the four isolated sections, stale air from a building or space returns through the third opening and passes through the energy recovery core to a fourth section of the four isolated sections and exits the airtight plenum through a fourth opening in communication with the fourth section of the four isolated sections.
