Sales - Panel Air Conditioner

Need for Panel Cooler

All electrical / electronic parts generate heat during operation which will affect the control logic; in turn reduces the life time, efficiency and sometimes may cause failure or damage to components which leads to down time or shutdown of production line.

Types of Panel Cooling

The compact panel cooler cools the overheated components by extracting head generated inside the panel, and prevents outside contaminants.

Cooling by Ambient Air

Panels which are having higher temperature than its ambient temperature,
cooled by a simple fan & filter units which supply fresh ambient air to the panel.

Cooling by Heat Exchanger ( Air to Water)

By using cold water in one side of heat exchanger other side panel air is cooled.

Cooling by Heat Exchanger ( Air to Air)

In which panel air and ambient air are separated by a heat exchanger.

Cooling by Air Conditioner ( Refrigeration system)

By using air conditioner panel air is cooled and circulated continuously in closed loop.

Advantages of Panel Air Conditioner
  • Panel cooler removes the heat from the panel on continuous basis to give constant temperature for the optimum performance of the equipment.
  • The internal air is passed through the cooling coil, which is at a temperature lower than dew point, so that all moisture in the air are condensed and come outside through drain pipe.
  • Panel cooler is closed loop in construction, does not allow the cool clean panel air to mix with the hot, humid and dirty outside air.
How to Select Panel Cooler
Calculation of Panel Inside Heat Load
Method I

The internal load of the enclosure is the amount of waste heat being generated inside the enclosure by electronics or other heat sources. Very often, this load is known and expressed in watts. Since

1 watt = 3.413 Btu/hr

It is easy to convert one unit to other

Method II

If the enclosure is using a fan or blower to pull outside air into for cooling, the difference in temperature (∆T) between the air entering and exiting the enclosure and the ambient of air is used estimate the internal load.
Internal load

(Btu/hr) = 1.08 * Flow (Cu.ft/min ) * ∆ T (oF)

Method III

Another way of estimation heat load is to use information provided by the manufacturer of the electronics that are inside the enclosure. They may often have an estimate of the amount of heat that the equipment is producing.
