KyungDong R&H Feature

■   Fans 
  
Fans shall be vane-axial induced type of cast aluminum ally blades.  
Low cost and high efficient running 
 

 

KyungDong R&H Feature  1

■   Water distribution nozzile 
  
The sater shall be distributed over the entire coil surface by precision molded ABS spray nozzle. 
 

KyungDong R&H Feature  2
 
■   Pan & casing  
  
Pan and casing shall be constructed of hot-dip galvanized steel gor long life and durability. 
 

KyungDong R&H Feature  3

■   Recirculation pump 
  
Pump shall be a close-coupled centrifugal type.IP54 motor for dirp-proof. 
 

KyungDong R&H Feature  4

■  Louver 
  
Air entrainment efficient is a good and the spray branches is minimum like as honeycomb. 

 

KyungDong R&H Feature  5
■   Eliminators 

Highly Efficient Removal of Arsenic Acid
Our drift eliminator efficiently removes up to 0.002% arsenic acid contamination of the circulating water flow by rapidly transforming the direction of air flow three times using air pressure. 
The user can extend the space of the drift eliminator supporter, making air flow resistance low. 
Notice: Saturated air meeting cold air produce the moisture you may see on the drift eliminator. Such moisture is normal and does not affect the device’s performance.  
 

KyungDong R&H Feature  6

■  Strainer 

Strainer shall be constructed of stainless steel NO304 for prevent the erodion and be apt to checking,dismantle,assembling and cleaning.

Comparison Criteria ■ Comparison Criteria ■ Forced Draft Type
The axial fanon the upper ventilator tube is positioned.on the side of an exposed tube.
Even air flowleaning to one side.

leads to the circulation of internal wind velocity.

Level of Noiserelatively low

relatively high
The use of a Centrifugal Fan helps reduce noise.

Repair, Maintenance

It is difficult for a Fan Motor to be checked, repaired and replaced.

It is easy for a Fan Motor to be checked, repaired and replaced.

Operating Cost

It is difficult for a Fan Motor to be

checked, repaired and replaced.

Due to significant air resistance, a characteristic of the forced

draft type, fan power expense increases by 40% or more.

Investment Cost1.01.6 ~ 1.9
UsagesFor a general outdoor typebasement installation-purpose is appropriate for its large aerodynamic resistance.
Air Recirculation Issues

The speed of air drain is faster than that of air suction

with little occurrence of air recirculation.

Air suction is fast while air drain is slow,

affecting air recirculation efficiency.

EVAPORATIVE CONDENSER Selection Method  

 on the ton of evaporation (Condensing Capacity)Method according to the calorific value based
Selection Method

1. Determine the number of evaporation tons,

condensing temperature, suction temperature, wet-bulb temperature.
2. Select an evaporative condenser according to evaporating

load and refrigerant type, each capacity factor by condensing

temperature and suction temperature.
3. Mainly applicable to standard open-type compressor.

EVAPORATIVE CONDENSER Load
250 Ton X condensing temperature x capacity factor x

capacity factor of suction temperature

1. Determine according to evaporation load, compressor’s

shaft power, condensing temperature and wet-bulb temperature.
2. Determine according to evaporation load, compressor’s

shaft power, condensing temperature and wet-bulb temperature.
3. Mainly applies to a sealed compressor, screw compressor and centrifugal compressor.
EVAPORATIVE CONDENSER CAPACITY
(evaporation load + shaft power ) x dissipation factor

Selection CriteriaㆍRefrigerant: Freon (R-22)
ㆍEvaporation ton load = 250Ton
ㆍCondensing temperature = 40℃
