An air conditioner includes an inverter circuit (10), a control unit (2) that controls the inverter circuit (10), a compressor (11) having a protection device (a pressure switch) (9), and a phase-voltage detection circuit (a U-phase voltage detection circuit) (6) that detects a ...
PURPOSE:To reduce a time for reaching a large car height position by providing a logic circuit which outputs a signal of operating a compressor immediately when a car height selector switch is switched from an ordinary car height side to a large car height side. CONSTITUTION:When a car height...
The pressure at which the mercury switch 25 will be actuated therefore depends on the adjustment of spring 60. Hence for each setting of the manual control knob 61 which de- 41 termines the tension of the spring 60 there will be a corresponding pressure acting on bellows Is which will ...
Pressure then rises to a level P2 and the pressure switch 4 is released to turn off the load command. Since the unload command can be lowered to the lowest guaranteed level of the target, the air flow is increased due to the pressure difference (P3-P1) and axial power is reduced.KIND...
The utility model relates to an air conditioning refrigerator by using pressure swing adsorption nitrogen-making device. The air conditioning refrigerator comprises a pressure swing adsorption nitrogen-making device, a moisture separator, a one-way valve, a nitrogen inlet pipe, a control switch, an ...
a battery 14 while the other end thereof is connected to coil 17 of a electromagnetic clutch handling the connection and disconnection of transmission from the engine to the compressor of the air adjusting device through a normally closed switch S1 to be opened or closed with a relay coil L....
If selection of the pressure selection switch is transmitted to a controller(70), the controller transmits air within a multi-stepped body by driving of an air compressor(80). If measured air pressure of a pressure sensor(90) arrives to set pressure, the controller stops operation of the ...
Now, when the air reduces and the liquid level increases to the determined position beforehand and then a liquid level detector 12 is closed, a coil for an electromagnetic switch 11 is present with current and an electromagnetic switch 10 is closed to start the compressor 1. After the ...
The air inlet pipe and the suction pipe are connected with the compressor by the reversing valve. The work of the compressor is controlled by the control switch. The utility model can realize the pressure increasing and reduction of the box body, and can cause the human body in the body-...
and feed through mutually through fluid pressure line and the pressure release switch of dress on the mobile device hand (hold), the utility model discloses installation convenient to use, easy operation can be to many screw air compressor's centralized lubrication, reduction in production cost, ...
