Evaporative Cooling System
An evaporative cooler is a device that cools air through the evaporation of water.
Evaporative cooling differs from typical air conditioning systems, which use vapor-compression or absorption refrigeration cycles.
Evaporative cooling works by exploiting water’s large enthalpy of vaporization.
The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor.
This can cool air using much less energy than refrigeration. In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants
Evaporative Cooling systems take advantage of the principles of latent heat of evaporation where heat is exchanged when water evaporates.
Evaporative cooling vs air conditioning
Evaporative cooling systems allows cool fresh air to circulate around the building forcing the stale hot air to out. Unlike air- conditioning which operates with re-circulated air. Evaporative coolers operate on the principles of air change and work as part of balanced ventilation system.
Most of the time outside air can be used to cool buildings; only on the hottest days does the cooling system kick in to cool the air before it is brought into the building.
Benefits Of Evaporative Cooling
Reduction in work place temperatures can improve staff morale, in turn increasing productivity and a reduction in absenteeism as well as
• A natural process without the need for refrigeration makes Evaporative Cooling an Environmentally safe solution.
• Odours and stale air are eliminated instead of being re-circulated.
• Cost Saving as running costs up to 90% less than an equivalent refrigeration system.
• Windows & doors can still be opened no detrimental effect on the efficiency or operating cost.
• Saves up to 10,000kg of carbon per year compared to an equivalent air conditioning system.
• Provides a natural environment and improves air quality.
Offices, warehouses, factories, shops or showrooms require cooling in summer months.
Until now the only option for a cooling solution has been refrigerant based air conditioning, restricting the usage to showrooms, offices & shops.
The price of Energy costs has made us focus energy efficiency and has raised questions about the sustainability of traditional air conditioning.
Evaporative cooling is the simplest method of cooling your building
With only a fraction of the moving parts of an air conditioning system and requiring only basic water and electrical service. Installation options allows us to provide customers with Bespoke systems to meet their needs. This can be simple louvered plenums through to fabric ducts perfect for office environments.
The unique design and process controls prevent water stagnation as the water in an evaporative cooler circulates at a naturally cool temperature so that Potentially dangerous organisms do not present a risk.
The plastic and stainless construction avoids corrosion.
A constant supply of naturally cooled air is supplied by the coolers without the use of environmentally damaging refrigerants.
An evaporative cooler can be upto 25% of the capital cost and 15% of the running cost of a refrigerant based industrial air conditioning system.
Eg: Breezair can produce 35kW of cooling for 1.5kW of power. This equates to one cooler providing enough cool air for 300m2 for a cost of less than 10 pence an hour.
Correctly designed Evaporative Cooling Systems can consume 85% less electricity than conventional air conditioning systems which equates to savings of 10 tonnes of carbon per annum per cooler.
