Gas absorption and release system and air conditioning system

The invention provides a gas absorption and release system and an air conditioning system. The gas absorption and release system comprises a first circulating pump, a gas absorption device and a gas release device, wherein the first circulating pump, the gas absorption device and the gas release device form an absorbent circulating flow path; a flow path between the outflow side of the gas absorption device and the inflow side of the gas release device can exchange heat with the heat supply device, or the gas release device can exchange heat with the heat supply device. According to the invention, when the absorbent flows through the gas absorption device, the absorbent can absorb indoor carbon dioxide, and when the absorbent absorbing carbon dioxide flows to the gas release device, the heat supply device can heat the absorbent; and the absorbent can release the carbon dioxide outdoors to be absorbed and utilized by plants when flowing through the gas release device, so that adsorption and desorption are carr
