What is condensing temperature in refrigeration?

The majority of the heat rejection is latent condensation from the refrigerant at a temperature above that of the ambient air. This is called the condensing temperature and, as a rule of thumb in this example, the condensing temperature will be 15K above the ambient air temperature, or 45°C.

What is the temperature of the condenser?

(The condensing temperature in any system is figured off of the condensing pressure using a pressure-temperature chart.) Condenser splits can range from 15 degrees to 30 degrees, depending on whether the condenser is a standard-, mid-, or high-efficiency unit.

Does a condenser lower temperature?

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.

How do you find the condenser saturation temperature?

So, if you are able to determine the pressure at any of these points (evaporator, condenser, or receiver), you can easily determine the “saturation” temperature by finding the measured pressure on the P-T card and reading the corresponding temperature.

What is the minimum condensing temperature for standard refrigeration units?

What is the minimum condensing temperature for standard refrigeration units? 90 degrees F. What are three common methods of head pressure control during low ambient?

How do you determine the condensing temperature?

The actual condensing temperature is the actual TD plus the ambient temperature: Actual Condensing Temperature = (Actual T.D.) + (Ambient) = 18.4 + 95 = 113.4°F.

What is 404A refrigerant?

R-404A is a pseudo-azeotropic mixed refrigerant composed of the three ingredients R-125, R-134a, and R-143a, and was developed as a substitute refrigerant for R-502 and R-22, used in commercial refrigerator equipment for low and medium temperature ranges.

What is the condensing temperature of R-404A?

How cold can R-404A get?

Is 404A a low temp refrigerant?

R404A is a zeotropic HFC refrigerant blend of R125, R143a and R134a. It is widely used in medium and low temperature refrigeration especially in the supermarket sector and for refrigerated transport.
