Indirect Evaporative Cooling Residential

This allows the airstream which contacts the outer wall to be sensibly cooled.

Indirect evaporative cooling residential.

Based on the principles of evaporation hot and dry outside air is pumped through water soaked cooling pads. The evaporative cooling cycle occurs in the heat exchanger. It is an excellent upgrade over conventional air washers. As the name suggests an evaporative air conditioner uses evaporation to help cool the air.

Direct and indirect evaporative cooling strategies. This cooling option is much more energy efficient than cooling with refrigerant standard air conditioning but it s not suitable for all cooling applications. The main difference with an indirect system is that a heat exchanger is used to cool the air supplied to the living space. Indirect evaporative cooling works on the same principle as direct evaporative cooling lowering air temperature by causing water to evaporate.

The evaporation of water cools one side of the heat exchanger while the other side provides a. To evaporate 1kg of water into an atmosphere 680w of energy is required. When the water evaporates the heat of vaporization imparts a cooling effect to the outer wall of the heat exchanger. Indirect evaporative cooling closed circuit is a cooling process that uses direct evaporative cooling in addition to some heat exchanger to transfer the cool energy to the supply air.

What is evaporative cooling. As the air is pushed through the cooling pads the water evaporates and the heat in the air is absorbed which. The indirect evaporative section also incorporates a scavenger fan to exhaust air through the pipes a water distribution system which includes a water pump and spray nozzles to provide a uniform distribution over the entire heat exchanger and a filter section to clean and maintain incoming air into the system. For steam humidifiers this energy typically comes from the electricity or gas being used to boil the water.

Indirect evaporative cooling sensible cooling no moisture addition followed by direct evaporative cooling adiabatic cooling. Indirect evaporative cooling occurs when water sprayed to the interior wall of a heat exchanger evaporates. This enables the idecool to deliver cool air at sufficiently reduced dry bulb temperature and low moisture level. A 2 stage evaporative cooling system aka indirect direct cooling represents the most advanced cooling system utilizing evaporative cooling technology.

However for cold water humidifiers this energy is taken from the air in the form of heat which results in a.
