Condenser Water Temperature Range

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.

Condenser water temperature range. With a 20td between refrigerant and water this puts the condensing temp 120 f. This is the temperature at which water droplets form. Condenser water temperature cooling towers are generally selected to supply 85 f water to the chiller condenser at design conditions i e when th e ambient wet bulb temperature equals design and the chiller is operating at full load. 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.

In other words the water in the return pipe needs to be 55c or lower or your boiler will. For natural gas boilers the dew point is around 55c. But these conditions rarely occur. Evaporation temperature 25 10 20 40 c according to the temperature and pressure table it is easy to find that the condensation pressure at this time is about1 55 mpa absolute pressure r410 refrigerant.

Accomadates more extreme conditions than 85f or using a drycooler or closed loop evaporative cooler. 3 gpm per cooling tower ton. But stay above 65 f 18 33 c. If the refrigerant is the same temperature as this return condenser water then the chiller will not be able to reject any heat that s been picked up in the building and so the building will be unable to cool down.

The condenser water enters at around 27 c 81 f so the refrigerant needs to be a greater temperature than this. Anytime you can provide condenser water lower than the design of 85 f 29 44 c you will lower your condenser pressure and lower the lift cond pressure evap pressure. When running building try to get your condenser water as low as possible when running.
