Water resistance detection device and method for fan coil

The invention provides a water resistance detection device and method for a fan coil. The device comprises a water source and pressure measuring devices, wherein the water source is respectively connected with the water inlet end and the water outlet end of the fan coil through connecting pipelines, and a water inlet valve and a water outlet valve are respectively arranged between the water sourceand the water inlet end of the fan coil and the water source and the water outlet end of the fan coil; and the pressure measuring devices are respectively arranged at the water inlet end and the water outlet end of the fan coil. According to the device and the method provided by the invention, water resistance detection can be directly carried out on the fan coil, problems are found and controlled from the source, and the frictional resistance condition of liquid flowing in an internal threaded pipe is reflected through the water pressure loss values of the water inlet end and the water outlet end and the line body w
