Many modern buildings require cooling either for the comfort of the occupants or to protect the processes or equipment they contain. There are three typical methods which can be employed to cool these buildings; ventilation, evaporative cooling or a refrigeration based air conditioning system. The choice of system can have a dramatic effect on the total carbon emissions of the building and the energy consumed due to their different electrical demands. See our Air Conditioning comparison to compare the features of Air Conditioning with Evaporative Cooling:

Evaporative and Ventilation (EcoCooling) Refrigeration and Air Conditioning
  • Typically uses less than 10% of the electricity than conventional air conditioning
  • No refrigerants
  • Supplies 100% fresh cool air
  • Low carbon dioxide footprint
  • Simple engineering
  • Low purchase cost
  • Can significantly reduce the temperature on very hot days
  • Low maintenance costs
  • High electrical use due to refrigerant circuit compressor
  • Uses environmentally damaging refrigerants
  • Uses mainly recycled air
  • High carbon dioxide impact
  • Complex engineering
  • High capital and operational cost
  • Performance reduces at high ambient temperatures
  • High maintenance costs

 

Ventilation systems can provide comfort cooling for most of the year. During prolonged periods of high temperatures, they are unable to maintain internal temperatures below 25°C. Refrigeration based systems are effective but can be expensive to operate and are not carbon friendly. Evaporative cooling, can produce air consistently below 22°C in the UK climate, provides an intermediate solution which consumes only a fraction of the electricity.  For more information on savings, please see the Safety and Energy Savings page.

Why use EcoCooling?

The EcoCooling range is the only evaporative cooler designed specifically for the UK and European industrial and commercial market. We have been in operation now for over 10 years and have more than 1000 installations in the UK, many of our clients have used us for several different applications. We have several large warehouses in Bury St Edmunds where we hold stock for all our coolers. We pride ourselves on our service to our clients and consider ourselves to be at the forefront of evaporative cooling technology.

Types of System:

Ventilation and Evaporative Cooling:

EcoCooleEcoCooling Roof Mounted EcoCoolers - Indsutrial Cooling - Factory/Warehousers are used as part of a mechanical ventilation system to provide a cost effective alternative to refrigeration for large buildings. Evaporative coolers have a supply air temperature dependent upon the ambient temperature and humidity.  On cool days this is the ambient (dry bulb temperature) and on hot days, when evaporative cooling is enabled, this is close to the ‘wet bulb’ temperature.

How Systems Work: General Principals
  • Fresh air is brought into the system through EU4 pre-filters and Munters CELdek® pads.
  • Evaporative cooling operates during warm periods to cool external air
  • An extract fan is specified to match the integral supply fan
  • Control systems automatically match air flow to the amount of cooling required.

End user applications for this system include:
Warehouses | Manufacturing Facilities | Mezzanine Floors | Production Lines | Bakeries | Laundries | Food Processing | Churches | Lecture Theatres |

 

Ventilation, Evaporative Cooling and Recirculation:

Side flow EcoCoolers - energy efficient evaporative cooling from EcoCooling

An evaporative cooler alone can result in supply air temperature variation during the day and throughout the year. This can cause issues in some applications such as IT cooling where either temperature variation or low temperatures are not acceptable.

To avoid these issues EcoCoolers can be incorporated into a system which uses attemperation. The hot air from the systems exhaust stream is mixed with the incoming cool air to provide supply air at a controlled temperature. A PLC (Programmable Logical Controller) sets the position of dampers to maintain a temperature set point. It also varies the fan speed to minimise energy use. Water use is optimised by evaporative cooling only being enabled when pure ventilation cannot maintain the desired temperature.

How Systems Work: General Principals
  • Fresh air is brought into the system through EU4 pre-filters and Munters CELdek® pads.
  • Evaporative cooling operates during warm periods to cool external air.
  • During winter periods warm exhaust air is mixed with cold fresh air. EcoCooling describes this mixing process as attemperation.
  • Low energy variable speed EC (Electronically Commutated) fans are specified to supply and extract air.
  • Patented control systems control air flow rate as well as supply and exhaust temperature.

End user applications for this system include:
Data Centres | IT | Comms | Schools and Classrooms | Lecture Theatres | Gyms and Fitness Suites | Restaurants | Venues | Theatres | Offices | Greenhouses |

 

Ventilation and Recirculation (Free Cooling):

ECV18000 ventilation and recirculation units - EcoCooling - Data centre cooling InstallationThe ECV range of units consists of a mechanical ventilation unit with attemperation. There is no cooling facility.  These products have been designed for buildings where temperatures occasionally exceeding 25°C are not considered to be of significant concern in rooms where free cooling can be used to supplement refrigeration equipment.  There is on average 300 days a year in the UK where free cooling can be used to replace refrigeration.

How Systems Work: General Principals
  • Fresh air is brought into the system through EU4 pre-filters.
  • During winter periods warm exhaust air is mixed with cold fresh air. EcoCooling describes this mixing process as attemperation.
  • Low energy variable speed EC (Electronically Commutated) fans are specified to supply and extract air.
  • Patented control systems measure and control air flow rate, supply and exhaust temperature.
  • Control systems automatically match air flow to the amount of cooling required.

End user applications for this system include:
Data Centre Cooling (Arctic Circle and Nordics) | Manufacturing Facilities | Production Lines | Cryptocurrency cooling | Bitcoin Mining cooling |

Barry Mosley, Clarks Group Facilities Manager sums up why he used evap cooling in his distribution centre in Street Somerset ….. “We required an environmentally friendly and low cost solution to the cooling of this area.  Clarks has a strong environmental ethos whilst still requiring commercially sound investments.  Evaporative cooling has only 15% of the carbon impact compared with conventional refrigeration based air conditioning and in addition EcoCoolers do not use potentially harmful refrigerants

Matalan– Centre Manager – Thurrock Store – “Temperatures in parts of the store pre-cooling were getting up to over 40°C making temperatures in the menswear section in particular intolerable. Temperatures are now 23°C throughout the store making shopping and working conditions ideal.”

Jo Dursley at Bristol Council  – “I am so impressed with the evap system. We had a demo of it working at full blast and you could not hear a thing. It is a beast of a machine in terms of the ducting pipes (which will be hidden in the ceiling void) but the actual box is not as cumbersome as I expected. I think its genius”
