| titleOfInvention | A leak-proof automatic water replenishment device for household central air-conditioning water system |
| abstract | The invention discloses an anti-leakage automatic water replenishment device for a household central air-conditioning water system, comprising an adjustable automatic water replenishment valve, a water replenishment normally closed solenoid valve, a pressure sensor, a water leakage protection control unit and an alarm module; The water inlet end is connected with tap water; one end of the water replenishment normally closed solenoid valve is connected to the water outlet end of the adjustable automatic water replenishment valve, and the other end is connected to the return water end of the central air-conditioning water system; the pressure sensor is installed on the solenoid valve and the water outlet. The connecting pipe between the water return ends of the central air-conditioning water system is used to detect the pressure value P of the central air-conditioning water system; the water leakage protection control unit automatically sets the upper limit P1 and lower limit of the automatic water replenishment according to the pressure value P and its interior The value P2 and the safety leakage point pressure value P3 can be compared and judged, which can accurately determine whether there is a water leakage accident in the central air-conditioning water system, and whether to send an alarm signal to the alarm module to inform the user, effectively avoiding the false alarm phenomenon of water leakage detection in the central air-conditioning water system. |
