Water Cooled Condenser Temperature

The water cooled condenser is the latent heat released by the cooling water to take away the refrigerant vapor condenser.

Water cooled condenser temperature. Condenser water temperature maximum leaving water temperature is 105 f on all models. Under the shell of the condenser we have multiple tubes inside. Condenser approach cond sat temp lvg cond water temp evaporator approach lvg water temp evap sat temp approach values should range in 0 3 f 0 k 1 65 k given that your flows are correct. Many catalogs will be based upon the ari standard of 20 d t between the incoming water temperature and the condensing temperature.

These run from one end to the other. In air cooled condensers the temperature difference between the ambient and the condensing temperature is referred to as the condenser split. Condenser water treatment the use of untreated or improperly treated water may result in scaling premature erosion or corrosion. Engineering aids total heat of rejection thr all units.

In water cooled condensers the refrigerant should condense at 5 10 k above the water inlet temperature a low value results in a not only higher cop but also higher initial costs. This is because 105 f is used for water cooled condenser condensing temperature. Water chillers the cooling tower is known to book a temperature of 25 degrees then how much is the condenser temperature of the water chiller. Just like on air cooled units where proper airflow is needed across the evaporator and condenser you need to verify that you have proper water flows.

The cooling tower water temperature into the condenser is assumed to be 85 f. The condenser water is flowing out at about 32 degrees celsius 90 degrees fahrenheit and it s returning at 27 degrees celsius 81 degrees fahrenheit. If you have chillers. Therefore the cooling water pressure is not enough the flow rate does not reach the rated requirement the heat dissipation capacity is limited and finally the temperature of the outer surface of the condenser rises.

With open type cooling towers the water should cool to within 3 6 k of the air wet bulb temperature and with closed cooling towers the water should be cooled to within 8 12 k of the air wet bulb temperature. For example if the condensing temperature is 110 degrees f and the ambient is 80 degrees the condenser split would be 30 degrees. A qualified water treatment specialist is recommended for proper results.
