Evaporative cooler - Wikipedia

Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate (that is, it has a large enthalpy of vaporization). The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation). This can cool air using much less energy than .

Newton's Law of Cooling Formula

2) A rod of iron is heated in a forge to a temperature of 1280.0K. The rod is then plunged in to a bucket of chilled water with a temperature of 280.0 K. After 10.0 s, the temperature of the iron rod drops to 329.7K. What is the cooling constant for this iron rod in water? Answer: The cooling constant can be found by rearranging the formula:

How to Build Your Own Aquarium Chiller

That's another reason for removing the aluminum ice cube divider and tray. The probe that is attached to the wall of the freezer area will now monitor the entire cavity. Set the refrigerator thermostat to the level that maintains the chilled water at the appropriate temperature to keep the aquarium temperature constant.

HVAC Chilled Water Distribution Schemes

pumping in chilled water distribution schemes, which we will study in following sections. _____ SCHEME #1 CONSTANT FLOW CHILLED WATER SYSTEM A constant flow system is the simplest chilled water distribution scheme. Here, a set of constant speed pumps distributes fixed quantity of water at all times and the temperature varies to meet the load.

Degrading Chilled Water Plant Delta-T: Causes and Mitigation

In most variable-flow chilled water plants, it is assumed that delta-T, the difference between return and supply chilled water temperature, will remain relatively constant. Because the load is directly proportional to flow rate and delta-T (Equa-tion 1), if the delta-T is constant, it follows that flow rate must vary proportionally with the load.
