The mass flow of the refrigerant through the tube cover increases the size of hypothermia increases. When liquid refrigerant enters the cap on the tube she was going through a linear differential pressure in length. Differential pressure unit length of the tube remains constant until this place, where has achieved the first vapor bubble forms. From this point to the end of the tube cover in the evaporator, the refrigerant pressure and temperature liquid-vapor mixture decrease in a linear fashion. This nonlinear reduction is connected with the increase of the share of the flashed steam in the pipe. Steam increases the resistance now, making greater pressure reduction unit length of the tube cover.
Refrigerant blinks whenever the temperature above the saturation temperature corresponding to the pressure. Because the pressure will decrease as the fluid flows through a pipe, flashing may be reduced by maintaining the temperature of the refrigerant below the saturation temperature corresponding to a decrease of pressure in the evaporator end of the cap tube.
Increase in the number of hypothermia, what happens in the capacitor allows the liquid to travel further through the cap of the tube before it starts flashing. The farther into the flow of a fluid, travel to the vapor bubble forms, the less pressure tube cover. As differential pressure decreases, the number of flashing decreases with increasing speed refrigerant flow increases. In summary, hypothermia improves the performance and capacity of the system. On the contrary, flashing reduce the capacity and speed of the refrigerant flow through the tube cover.
The mass flow of the refrigerant is reduced, because the quality of the refrigerant increases. Quality is the percentage of vapor per unit mass of the refrigerant. Refrigerant having a quality 100% fully pair of refrigerant quality 30% - 70% of the liquid. Improving the quality of the refrigerant in the cap of the tube indicates that the amount of fluid in the pipe falls. Based on the previous sections, and as a refrigerant in the cap of the tube increases the resistance of the refrigerant flow through the cap of the tube and the pressure also falls with increasing mass flow is reduced...
