Water source air handling unit Details

Application Scenarios:

Hisurp Water source air handling unit is suitable for ventilation cooling of electrical cabinets in which the indoor temperature of the electrical room is ≤40℃ and indoor condensation is not allowed, such as:

high-voltage inverters, fans, pumps, compressors, rolling mills, etc. --

*in large mining production plants, the petrochemical industry, municipal water supply,

*metallurgy and steel, electric power and energy industries, and other industries 



Hisurp Water source air handling unit has:

◆ Main components: axial fan, heat exchanger.

◆ heat exchanger with copper tube cased hydrophilic corrugated aluminum fin, and mechanical expansion, with high heat exchange efficiency

◆ fans from well-known brands, with low noise and high air volume

◆ fault detection, sound & light alarm for liquid leakage and fan failure, antifreeze and other functions, to ensure a clean and dry indoor environment, providing a safe and stable guarantee for the operation of the inverter.

◆ easy structure, easy installation


System Diagram Preview:

There are two types of system solutions for a water-source air handling unit for high-voltage inverters
System solution (I): duct system
1. The unit will be directly connected by ducts to the exhaust port of the top of the cabinet of the inverter, which improves the heat exchange efficiency and can directly cool down the heat discharged from the inverter.

System solution (II): hot air area system
1. A compartment above the entire electrical cabinet, directly connected to the exhaust port on the top of the cabinet, and the unit cools the hot air inside the compartment.


Both solutions will be set:
2. The cooling water pipeline is outside the high-voltage inverter distribution room to avoid threats to high-voltage equipment when the cooling water pipeline leaks or breaks to ensure safety and avoid accidents.
3. Indicators like air outlet, wind speed, wind pressure, etc should be calculated, in order to prevent water condensation from entering the room by air outlets during the cooling process; under the condition of ensuring good discharge pressure, it makes the equipment run safely and stably.
4. when the unit shutdown due to failure, it can automatically open the emergency vent even unattended, discharging hot air to ensure the safe and normal operation of the inverter.
