A controlling device for indoor apparatus includes a detection module, a human machine interface (HMI) and a wireless transmission module. The controlling device accepts supervisor's setting for an indoor electronic apparatus via the HMI, detects the environment around the controlling device for generating a plurality of detection value via the detective module, and receives another detection value from a plurality of slave detection devices in same controlling system. The controlling device generates a control command based on setting parameter of the supervisor and the plurality of detection value, and transmits the generated control command to the indoor electronic apparatus via the wireless transmission module. The indoor electronic apparatus works based on the received control command, so the environment around the controlling system can satisfy supervisor's demand.

Controlling device, controlling system and controlling method for indoor apparatus

A refrigerant socket includes an accommodating body and a pipeline assembly. The pipeline assembly includes a refrigerant pipe connecting to the accommodating body and having an inner section inside the accommodating body and an outer section outside the accommodating body; a switch placed at the inner section and away from a free end thereof, the switch being used to selectively allow or block a flow inside the refrigerant pipe; a refrigerant pumping pipe communicating between the free end of the inner section and the switch; and at least one joint communicates between the free end of the inner section and the switch. Therefore, even if the diameter of the refrigerant pipe does not match an air conditioner indoor unit, connection can still be made without the need of removing the original piping, thereby avoiding wasting refrigerant.

An over-voltage protection apparatus includes an input voltage detection module () and a second switch (). The input voltage detection module () includes a switch assembly (), a rectifying circuit (), a voltage detection circuit (), and a voltage protection circuit (). The rectifying circuit () rectifies an AC power source (Vac) to generate a DC voltage (Vb). The voltage protection circuit () controls the second switch () to disconnect the AC power source (Vac) to supply a load () when the voltage detection circuit () detects that the DC voltage (Vb) reaches to a first over voltage value (Voth). The voltage protection circuit () controls the switch assembly (), thereby providing a voltage-limiting protection and a current-limiting protection when the voltage detection circuit () detects that the DC voltage (Vb) reaches to a second over voltage value (Voth).

A cooling system of a server with an AC power source and a DC power source includes an AC input subsystem, a DC input subsystem, and a driving control subsystem. The AC input subsystem receives an external AC power source and provides a first DC voltage and a second DC voltage. The DC input subsystem receives an external DC power source and provides a third DC voltage and a fourth DC voltage. When the external AC power source normally works, the driving control subsystem controls the first DC voltage and the second DC voltage to supply a high-voltage cooling apparatus and a low-voltage cooling apparatus, respectively. When the external DC power source normally works, the driving control subsystem controls the fourth DC voltage and the third DC voltage to supply the high-voltage cooling apparatus and the low-voltage cooling apparatus, respectively.
