Embodiment 1

[0031] Such as figure 1 As shown, this embodiment includes: the protector body 1 is arranged before the water inlet of the heat exchanger, the refrigerant side fluid temperature (pressure) detection element 3 of the heat exchanger is arranged at the refrigerant fluid outlet, and the water outlet temperature detection is arranged at the water outlet of the waterway. Part 4. Water outlet temperature detection part 5 inside the waterway, flow detection part 6, detection part controller 7 arranged on the protector body 1, and inlet water temperature detection part 9 arranged on the water inlet end of the water path, of which: the protector body 1 The two ends are respectively arranged at the water outlet and inlet of the waterway. The flow detection element 6 is arranged inside the protector body 1, and the detection element controller 7 receives the work instruction A of the external system, and then collects the refrigerant of the heat exchanger The output signals of the side flui...

Embodiment 2

[0039] Such as image 3 As shown, for the monitoring method described in Embodiment 1, the detection component controller 7 receives the work instruction A of the external system, and then according to the collected heat exchanger refrigerant side fluid temperature (pressure), outlet water temperature, water flow and Inlet water temperature, monitor abnormal conditions of specific working conditions, when it is judged to be abnormal under specific working conditions, the detection unit controller 7 outputs relevant signals;

[0040] Specific working conditions include but are not limited to: start state, normal operation state, defrost state, static shutdown state, blocked dirty state and extreme freezing state;

[0041] Startup state: The water flow through the heat exchanger is detected before the compressor of the refrigeration main engine is started. When the water flow meets the set value, the unit is allowed to start. During the start-up process, the water flow rate, the inle...

Embodiment 3

[0050] The air conditioning system of this embodiment uses the integrated waterway protector of Embodiment 1. The integrated waterway protector is set on the chilled waterway of the air conditioning system, wherein: the water inlet end of the integrated waterway protector is set on the chilled waterway return pipe, The water outlet is arranged at the water inlet of the evaporator of the air-conditioning refrigeration host.

[0051] The detection component controller in the integrated waterway protector uses the monitoring method described in Embodiment 2.

Abstract

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.

Description

Technical field [0001] The invention relates to a device in the technical field of safety control in a temperature regulation system, in particular to an integrated waterway protector used in water circuits related to air conditioning, refrigeration or heating systems to ensure the reliable operation of heat exchangers. Background technique [0002] With the advancement of technology, a large number of more efficient plate heat exchangers are used in existing air conditioning units. However, in current supporting engineering applications, water quality requirements are based on traditional shell and tube heat exchangers, which cannot fully meet the higher requirements of plate heat exchangers. Claim. [0003] After searching the prior art, it is found that Chinese Patent Document No. CN202813660, published on 2013-03-20, records an antifreeze protection device for air conditioning chillers, including UPS power supply, relays, condensers and evaporators. A normally closed solenoid ...
