Integrated hvac and direct carbon capture system and method

A method of operating a heating, ventilation, and/or air conditioning (HVAC) system, comprising:

• establishing a first heat exchange relationship between a refrigerant present in a first heat exchanger of a refrigeration circuit of the HVAC system and a first airflow generated by a first fan of the HVAC system;
• establishing a second heat exchange relationship between the refrigerant present in a second heat exchanger of the refrigeration circuit and a second airflow generated by a second fan of the HVAC system;
• absorbing or adsorbing, from the first airflow, greenhouse gas via a solvent present in a first vessel of a greenhouse gas removal circuit of the HVAC system, wherein the first vessel is adjacent to the first heat exchanger;
• biasing the solvent from the first vessel to a second vessel of the greenhouse gas removal circuit, wherein the second vessel is adjacent to the second heat exchanger;
• and
• separating the greenhouse gas from the solvent at the second vessel via heat rejected by the second heat exchanger and present in the second airflow.

A heating, ventilation, and/or air conditioning (HVAC) system, comprising:

• a heat exchanger;
• a fan configured to direct an airflow over the heat exchanger;
• and
• a vessel positioned adjacent to the heat exchanger, wherein the vessel is configured to:
• receive the airflow directed across the heat exchanger;
• and
• absorb or adsorb a greenhouse gas within the airflow in a solid solvent present in the vessel.
