In the condenser, why is the temperature of the cooling water too low, causing the condensation pressure to be too low?

This is because when the temperature of the cooling water in the condenser is too low, a partial vacuum phenomenon occurs due to thermal expansion and contraction of the gas and an increase in the liquefaction speed of the vapor. Therefore, under the combined effect of these two aspects, the pressure in the condenser is drastically lowered, and further, the condensing pressure is too small.

Horizontal shell tube water-cooled condenser, why is it better to place it horizontally? For the condenser of the horizontal shell-and-tube water-cooled condenser, the reason for the horizontal placement is that the water pipes in the condenser are generally arranged longitudinally, so that horizontal placement can effectively reduce The water flow resistance does not affect the water flow rate and the heat exchange efficiency of the condenser. Therefore, this conclusion will be reached.

What is the saturation temperature of the condenser? The saturation temperature of the condenser, in general, refers to the temperature at which the condenser is unable to condense inside the refrigerant. This temperature is the saturation temperature of the condenser. Because the refrigerant is in a condenser, it is condensed into a liquid state by a gaseous state. Therefore, the above definition will be available.

Is it related to cooling water regardless of the condenser? This is definitely and certain, so the answer is yes. Because, whether it is an evaporative condenser or a plate condenser, etc., the temperature rise of the water is used to carry away the heat, thereby causing condensation. Therefore, it is related to the temperature of the cooling water, and the relationship is still large.
