Abstract: A temperature measuring circuit, measuring apparatus and a measuring method thereof relating to the field of electronic circuits. The temperature measuring circuit includes control unit, wherein the control unit includes a first current output interface, a second current output interface, a first input/output interface, a second input/output interface, and a third input/output interface. Further, the first current output interface and the first input/output interface of the control unit are respectively electrically connected to a first interface of a temperature sensor; the second current output interface and the second input/output interface of the control unit are respectively electrically connected to a second interface of the temperature sensor; and the third input/output interface of the control unit is electrically connected to a third interface of the temperature sensor.

Abstract: A water chiller, a water output adjustment method, and an air conditioning system. The water chiller includes: at least two cooling towers used in parallel, a water pressure balance adjustment circuit, and a main control hoard, where each of the at least two cooling towers includes a water pressure pre-adjustment circuit, the main control board is configured to control the water pressure pre-adjustment circuit to realize real-time water output adjustment of the each of the at least two cooling towers, and control the water pressure balance adjustment circuit to achieve a water output balance adjustment among-multiple cooling towers.

Abstract: An equipment unit state controlling method and device, and an equipment unit. After receiving control data transmitted from a state controller, a unit controller detects whether the unit controller communicates with a display panel controller, in which the state controller transmits the control data to the unit controller and the display panel controller simultaneously. If the unit controller communicates with the display panel controller, the unit controller performs an operation on the equipment unit corresponding to instruction information transmitted from the display panel controller, and if the unit controller does not communicate with the display panel controller, the unit controller parses the control data by itself to obtain the parsing result and performs the operation on the equipment unit corresponding to the parsing result.
