Instead of having to use the Print Screen button and then paste into Paint (or a similar application), you can now automatically save a screenshot to the Pictures folder as a png with just the touch of a couple of buttons. Here's how. 1.
Thermostatic expansion valve or TEV is one of the most commonly used throttling devices in the refrigerator and air conditioning systems. The thermostatic expansion valve is the automatic valve that maintains proper flow of the refrigerant in the evaporator as per the load inside the evaporator.
Thermostatic Expansion Valve Capacity. The capacity of a TXV differs due to orifice size, pressure difference between high and low side, and the temperature and condition of the refrigerant in the liquid line. The amount of liquid that will flash to a vapor will increase with a rise in liquid line temperature.he three forces which control the operation of the thermal expansion valve are: P1 â The vapor pressure of the thermostatic element (a reaction to the bulb temperature) which acts to open the valve. P2 â The evaporator pressure which acts in a closing direction below the diaphragm.
