Figure 1B is primary, spare air-conditioning system and electronic switching device annexation figure;
Fig. 2 A and Fig. 2 B are switching controls case control principle drawing;
Fig. 3 is the control signal case chamber door layout of equipment.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to accompanying drawing 1A, Figure 1B, Fig. 2 A, Fig. 2 B and Fig. 3, the electronic switching device of the standby unit of minitype air conditioner, comprise the control signal case, switching controls case, electrically operated valve and the control cables that connect successively, primary and backup air-conditioning system pipeline is respectively by described electrically operated valve access user end air-conditioning system equipment, referring to accompanying drawing 1A.
Switching controls case circuit theory diagrams are shown in Fig. 2 A and Fig. 2 B, generally can be incorporated in guest machine group power distribution cabinet, if this power distribution cabinet is existing device, also can independently be arranged on by guest machine group power distribution cabinet.This switching controls case is the nucleus equipment of this switching device, by it, completes all functions that the standby unit of minitype air conditioner and electrically operated valve thereof are carried out to one-touch switching control, specifically sees course of work explanation.
Control signal case apparatus arrangement is shown in Fig. 3, is arranged near electrically operated valve or other are convenient to the place that user observes operation, realizes the one-touch control in a distant place and has capital equipment supervisory signal and failure alarm signal.
Control cables is used between switching controls case and control signal case and the electrical connection between control signal case and motor-driven valve.
Specific embodiment is referring to accompanying drawing 1B, certain office block, respectively active/standby with access user end air-conditioning system equipment after air-conditioner water system pipeline installing electrically operated valve, by the control of electrically operated valve and the chain automatic switching of realizing the standby unit of minitype air conditioner of necessary standby air-conditioning unit with and stop using and reset.
The course of work:
