How does the tower height affect air water contact in a cooling tower?
As it trickles down, it contacts ambient air rising up through the tower either by natural draft or by forced draft using large fans in the tower. That contact causes a small amount of the water to be lost as windage or drift (W) and some of the water (E) to evaporate.
What is the relation between range and height of a cooling tower?
However, at higher capacities, the approach would increase. Range is a direct function of the quantity of water circulated and the heat load. Increasing the range as a result of added heat load does require an increase in the tower size.
What is TR capacity in cooling towers?
Some commercial and industrial refrigeration systems are rated in Tons of Refrigeration (TR, tons). A ton is the amount of heat removed by an air conditioning system that would melt 1 ton (2000 lbs.)…Converting between Btu/h and Tons of Refrigeration.
| Btu/h | Refrigeration Ton | kW |
|---|---|---|
| 54000 | 4 1/2 | 15.8 |
| 60000 | 5 | 17.6 |
How do you calculate water for a cooling tower?
Let’s calculate each component.
- Evaporation loss = 0.00085 x 10 000 x (100-85) = 127.5 gpm.
- Drift loss = 0.02% x 10 000 = 2 gpm.
- Blowdown = [127.5 – (5-1) x 2]/(5-1) = 29.87 gpm.
- Cooling tower makeup water = 127.5 + 2 +29.87 = 159.37 gpm.
What is the application of cooling tower?
Cooling towers are primarily used for heating, ventilation, and air conditioning (HVAC) and industrial purposes. Cooling towers provide a cost-effective and energy efficient operation of systems in need of cooling. More than 1,500 industrial facilities use large quantities of water to cool their plants 2.
Is a cooling tower a condenser?
Cooling towers and condensers both heat exchanger equipment but operate in opposite ways. Condensers turn a substance from gas to liquid by way of cooling it (with either air or water that would come from a cooling tower).
What is the function of the AC condenser?
The purpose of the condenser is to receive the high-pressure gas from the compressor and convert this gas to a liquid. It does it by heat transfer, or the principle that heat will always move from a warmer to a cooler substance.
What is the primary function of a compressor?
The purpose of the compressor is to circulate the refrigerant in the system under pressure, this concentrates the heat it contains. At the compressor, the low pressure gas is changed to high pressure gas.
What is the function of a condenser coil?
While the evaporator coil picks up heat from indoor air, the condenser coil releases heat into outdoor air. The load of heat energy extracted from your home and compressed in hot refrigerant vapor is rapidly released when refrigerant circulates into the coil and condenses to liquid.
