How to test and measure the cooling effect of the cooling tower?
With the implementation of national energy conservation and emission reduction measures and the shortage of water resources, in recent years, closed cooling towers have been used in iron and steel metallurgy, power electronics, machining and air conditioning systems and other industries. Closed cooling tower (also known as evaporative air cooler or closed cooling tower) tubular heat exchanger is placed in the tower to ensure cooling effect through heat exchange of circulating gas, spray water and cooling circulating water. Considering the closed cycle, it can ensure that the water quality will not be polluted by the environment, and can well maintain the efficient operation of the host, and extend the service life. When the external temperature is low, the sprinkler system can also be disabled to save water. Do you know how to measure the cooling effect of cooling tower? Now, Wuxi Jiahe Cooling Equipment, a manufacturer of closed cooling towers, begins to introduce three indicators commonly used to test the cooling effect.
(1) The difference between the inlet temperature t1 and the outlet temperature t2 of the cooling tower is t. Δ T is called the cooling water temperature difference. Generally speaking, the greater the temperature difference, the better the cooling effect. For manufacturing, larger Δ T will reduce the total flow of cooling water required by the production line equipment. However, if the inlet water temperature t1 is high, even if the temperature difference Δ T It is too large to reduce the water temperature after cooling to meet the requirements. Therefore, although such indicator value is necessary, it reflects insufficient problems.
(2) The degree of cooling water temperature t2 and wet bulb temperature t. T_ T_ 2 - (CHIS) T is called overall cooling width. Δ The smaller the t 'value is, the better the cooling effect is. actually, Δ T 'cannot be equal to zero.
(3) The density of dripping water is taken into account when calculating the cooling tower. Water spray density refers to the amount of water that can be cooled on a reasonable area of 1m2 per hour. It is indicated by the symbol q. Q&QFM3/M2.HQ Total flow of cooling tower M3/H; F Reasonable water spraying area of cooling tower M2
Common expressions for basic conditions of circulating water volume of clarification cooling tower:
One. Cooling water and main engine cooling capacity (kW) 1.21.25861/5000 (m3/h)
b。 Cooling water volume=heat load of main condenser (kcal/h) × 1.2/5000 (m3/h)
C。 Cooling water and heat load (M3/H) x1.2 (M3/H)
d。 Cooling water volume=cooling capacity of main engine (cold ton) × 0.8 (m3/h)
e。 Cooling water heat load (kcal/h)
F。 Cooling water of main evaporator=heat load (m3/h) 1.21.25 (m3/h)
G。 Cooling water=heat load of evaporator (cold ton)
Note: above: 1.2 is the motor selection capacity, 1.25 is the condenser load index.
H。 The cooling capacity of broadband lithium bromide host per 1 million kcal is:
Working conditions ①: 37.5/32/28. (cooling water output: 300 × 330m3/h) and 350-400 towers;
Working condition 2:37/30/28 (cooling water output: 248m3/h), tower 450%
The above is the calculation method of how to test the cooling effect of the cooling tower. If you want to test the cooling effect of the cooling tower, you may want to test and calculate according to the above!
