What does the saturation temperature of the refrigerant in the condenser correspond to?
the saturation temperature of the refrigerant (the temperature at which the refrigerant changes from a liquid state to vapor. This is the same as its boiling point. For water at sea level, the saturation temperature is 212F.
What is condenser outlet temperature?
The condenser outlet temperature is typically 130-145 °F (54-63 °C) depending on ambient temperature and is normally designed for an 20-30 °F (11-16 °C) approach to the maximum ambient temperature.
Will low ambient temperature over an air cooled condenser increase or decrease condenser capacity?
Condenser splits are not affected by ambient changes. If there is an increase in the ambient temperature, there will also be an increase in the condensing temperature, but the condenser split (difference between the two temperatures) will remain the same.
What would an abrupt temperature change at the center of the condenser indicate?
What would an abrupt temperature change at the centre of the condenser indicate? The condenser is restricted at the temperature change point.
What is the effect on temperature of cold and condensing fluid while passing through the condenser?
Temperature profile inside the condenser The temperature of the refrigerant decreases during the desuperheating and sub-cooling processes, but remains constant during the condensing process (see Figure 7.3). The energy rejected from the refrigerant heats the secondary medium, whose temperature thus increases.
What does saturated condensing temperature mean?
The term “saturation” comes from the fact that it is the temperature that a liquid has to be at to boil and enter the vapor phase, based on its saturation pressure. At constant pressure, if you remove heat and have a vapor at its saturation temperature, it will condense and become a liquid.
Does a condenser lower temperature?
What is the usual temperature difference between the inlet and outlet of the condenser?
The temperature difference between inlet and outlet water (ti – to) is normally in the range 10 – 15 oF. The water consumption – or the amount of make up water – of a cooling tower is about 0.2-0.3 liter per minute and ton of refrigeration.
What effect does ambient temperature have on the efficiency of an air-cooled condenser?
As the ambient temperature increases to 40 °C, the temperature differential decreases, thus lowering the efficiency of the condenser and reducing the cooling power.
What determines condensing temperature in refrigeration?
such as air-cooled water chiller, the condensing temperature mainly depends on the ambient temperature, while the evaporating temperature depends on which field applies to, the evaporating temperature of the air-conditioning is higher, the refrigerating temperature is lower, and the freezing temperature is lower.
How is condenser temperature difference?
In air-cooled condensers, the temperature difference between the ambient and the condensing temperature is referred to as the condenser split. For example, if the condensing temperature is 110 degrees F and the ambient is 80 degrees, the condenser split would be 30 degrees.
