Self-adaptive environment temperature water system air conditioner

The invention discloses a water system air conditioner self-adaptive to environment temperature, which is characterized in that a refrigerant circulating water pump inputs refrigerant water into a water system air conditioner host assembly for refrigeration or heating process, and then outputs the refrigerant water to a plurality of tail end fan coils mounted in a comfortable environment space through pipelines, so that heat exchange of the comfortable environment space is realized; and then the cold and hot medium water flows back into the cold and hot medium circulating water pump, and the target of controlling the internal temperature of the comfortable environment space is achieved through continuous circulation. The system control cabinet collects data monitored by the environment temperature monitor through a data line, the working temperature and state of the water system air conditioner host assembly are controlled in a self-adaptive mode, meanwhile, starting and stopping and abnormal protection of th
