Why is the evaporator in the refrigerant pressure, the lower the flow rate, the better the heat absorption?
So the evaporator frost, ice is not a good thing, and you do not let the evaporator condensation is impossible.
And when the evaporator refrigerant pressure is too low, it will lead to evaporator frost and even ice and affect the heat transfer effect.
For the evaporator heat transfer effect alone, the lower the refrigerant pressure, the lower the temperature of the refrigerant itself, the corresponding evaporator heat transfer temperature difference, good heat transfer effect.
