The invention discloses an integrated water
route protective device, and belongs to the technical field of
safety control of
temperature control systems. The integrated water
route protective device is used on water routes relative to air conditioners or freezing systems or heating systems, and can ensure the reliable operation of a
heat exchanger. The integrated water
route protective device comprises a protective device body, a
fluid temperature detection part, an outlet
water temperature detection part, a flow detection part, a detection part controller and an inlet
water temperature detection part, wherein the
fluid temperature detection part is arranged on the side of a cooling agent of the
heat exchanger, the outlet
water temperature detection part is arranged at the water outlet end of a water route, the detection part controller is arranged on the protective device body, and the inlet water temperature detection part is arranged at the water inlet end of the water route. Two ends of the protective device body are correspondingly arranged at the water outlet end and the water inlet end of the water route respectively, the flow detection part is arranged in the protective device body, and the detection part controller receives a working order of an external
system, then collects output signals of the
fluid temperature detection part arranged on the side of the cooling agent of the
heat exchanger, the outlet water temperature detection part, the flow detection part and the inlet water temperature detection part, judges abnormal conditions of specific working conditions, and outputs early warning signals. The integrated water route protective device can improve reliability of
system operation, and effectively avoid the situation that the heat exchanger looses effectiveness due to filth blockage or misoperation.
