Which of the following statements are TRUE? Power does not need to be turned off before the device is inserted or removed. Types of Bus External bus or Expansion bus allows the CPU to talk to the other devices in the computer and vice versa. As a result, the refrigerant liquid level in the evaporator or the low-side float Therefore, the expansion device has to make sure that the amount of liquid fed into the expansion zone, will be completely boiled at the end of the evaporator. The reverse D. 86. Some additional controls to control the capacity of compressor and the space temperature may be required in addition, so as to minimize the energy Refrigerators and Air conditioners have four important components: the compressor, the condenser, the throttling or expansion device and the evaporator. Expansion slots – provide expansion capability to add hardware components beyond what was originally installed; Ports – provides an interface between the computer and a peripheral device such as a mouse, keyboard, or printer; All of the above components are labeled in Figure 1. increased load, as a result the liquid level drops back to the original level. and acceleration. Want to see the full answer? Some of the most commonly used types of throttling valves are: Capillary tube. a) High Side Float Valve The common types of expansion valves or devices: The, capillary tube, and. SSHDs. Video cards connect to a display device, such as a monitor or television. Domestic refrigerator working on vapour compression cycle uses the following type of expansion device_____? d) In a capillary tube pressure drop takes place due to fluid friction . To add features to your computer, you can typically add a peripheral card to an existing bus slot. When the An expansion bus is an assortment of wires that allows for computer expansion with the use of an expansion board, a printed circuit board inserted into an expansion slot on the motherboard or backplane that provides additional features to a computer system. Reference. evaporator or a float chamber attached to the evaporator. The float then moves in such a way that the valve Following on Altair-8800's debut, Intel began manufacturing expansion slots on a large scale for use in the corporate sector. chamber drops momentarily. consumption. a) A capillary tube is a variable opening area type expansion device. A _____ is a device driver that includes a digital signature proving who published the device driver and whether the device driver has been altered. The word “capillary” is a misnomer since surface tension is not important in refrigeration application of capillary tubes. Types of Expansion Valves. Types of Bus External bus or Expansion bus allows the CPU to talk to the other devices in the computer and vice versa. When you hear PC, you probably envision an enclosed device with an attached video screen, keyboard and some type of a pointing device, like a mouse or touchpad. As shown in Which type of internal laptop hard drive combines high performance and capacity at a relatively low device cost? Keyboard 17. Power does not need to be turned off before the device is inserted or removed. You must be logged in to read the answer. process occurs when the load falls, i.e., the float reduces the opening of the There are seven main types of expansion devices: Thermal expansion valves (TEVs) Manual valves; Capillary tubes; Automatic valves; Electronic expansion valves Float valves •Constant restriction types 1.
