Device capable of accurately controlling temperature and humidity

The utility model provides a device capable of accurately controlling temperature and humidity. The device capable of accurately controlling temperature and humidity comprises a temperature control coil, dehumidifying coils, and a hot water pipeline and a cold water pipeline communicated with hot water and cold water. The hot water pipeline and the cold water pipeline respectively and sequentially pass through electromagnetic valves, the temperature control coil, and three-way valves connected in series to respective pipelines to form two temperature control water loops. A third three-way valve is also connected to the cold water pipeline. The cold water pipeline is connected with a water inlet of the dehumidifying coils. A water outlet of the dehumidifying coils is connected with the third three-way valve. The device capable of accurately controlling temperature and humidity has simple control pipelines, a compact structure and strong adaptability, automatically adjusts the cold and hot water flow entering t
