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.
The expansion valve removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator. The high-pressure liquid refrigerant entering the expansion valve is quite warm. This may be verified by feeling the liquid line at its connection to the expansion valve. The liquid refrigerant leaving the expansion valve is quite cold. The orifice within the valve does not remove heat, but only reduces presÂ­sure. Heat molecules contained in the liquid refrigerant are thus allowed to spread as the refrigerant moves out of the orifice.
