The operation method of waste water residual heat driving type air conditioner VMC (Ventilation Mechanical Control System) the most according to claim 7, it is characterized in that, cold water water compensating valve is had owing to the water inlet end of described vapotron connects, the water side of described vapotron connects blowoff valve, when being arranged on the water temperature over-high that the temperature sensor of water side of described vapotron detects in described chilled(cooling) water return (CWR), open described cooling water compensating valve and described blowoff valve, utilize cold water to be replaced by recirculated water too high for temperature.
The operation method of waste water residual heat driving type air conditioner VMC (Ventilation Mechanical Control System) the most according to claim 7, it is characterized in that, when being arranged on the humidity sensor of air inlet in air conditioning chamber and the comfortableness requirement that the air humidity sent in air-conditioned room is unsatisfactory for people being detected, control described first electromagnetic valve and described second electromagnetic valve, described chilled(cooling) water return (CWR) is switched to described residual heat waste water pipeline, residual heat waste water enters solution inlet and the solution inlet of described second dehumidification heat exchange of described first dehumidification heat exchange, heat makes the desiccant desorption moisture regeneration in described first dehumidification heat exchange and described second dehumidification heat exchange, recycled；The moisture of desorption is taken away by the air in airduct；After the regenerative process of described first dehumidification heat exchange and described second dehumidification heat exchange completes, control described first electromagnetic valve and described residual heat waste water pipeline is switched to described chilled(cooling) water return (CWR) by described second electromagnetic valve, move in circles.
