Condensation heat recovery system and method

The invention relates to the technical field of condensation heat recovery equipment, in particular to a condensation heat recovery system and method, and the condensation heat recovery system comprises an air inlet pipe, a containing mechanism and a heat recovery mechanism; heat exchange liquid is contained in the containing mechanism; the heat absorption part of the heat recovery mechanism is immersed in the heat exchange liquid; one end of the air inlet pipe is connected with the air outlet end of the constant-temperature and constant-humidity machine; according to the designed condensation heat recovery system and method, waste gas exhausted by the constant-temperature and constant-humidity machine is conveniently introduced into heat exchange liquid through the gas inlet pipe, heat of the waste gas is conveniently absorbed through the heat exchange liquid, meanwhile, the heat exchange liquid can absorb harmful impurities in the waste gas, and the quality of the external environment near a working area is
