With each year, in conditions of global climate change, the task of providing comfort and safety for participants, so for spectators on mass sports events becomes more relevant. Increased average temperature levels and an increased number of extremely hot days have led to the necessity of new solutions for the protection of people’s health. One such solution became mist cooler for rent, which proved their effectiveness already in many arenas of world significance.
For example, in 2020, a study showed that with the use of devices, the average temperature of sports objects decreased on average by 12 degrees Celsius, which noticeably increased comfort for all present.
Technical miracle: How to work mist coolers
Mist coolers represent themselves as engineering systems that spray the smallest drops of water, creating the effect of artificial fog. This fog evaporates, absorbing heat from the surrounding environment and thereby lowering the temperature of the air in zone coverage.
Usually, such devices are capable of cooling air to 15 degrees Celsius below the surrounding temperature, which is especially relevant in conditions of summer heat. Similar technologies are applied on large open areas and stadiums, where required quick and effective cooling.
Main advantages use mist coolers
- Effective reduction temperature: To 15 degrees Celsius, which is confirmed by data from more than 30 large sports events.
For example, during the Olympic games in Tokyo in 2020 year, the temperature in main sports venues, thanks to mist coolers, decreased by 10-12 degrees. - Economy: Minimal consumption of resources allows the possibility of frequent use without significant costs. In comparison with traditional systems of air conditioning, the costs of using coolers are 40% lower.
- Friendly for health: Absence harmful chemical emissions.
- Mobility and simplicity installation: Most models can be installed and moved in counted hours.
Limitations and technical nuances
- Influence humidity: Problems with effectiveness in conditions more than 70% relative humidity, which was noticed in events in Zone Red Sea and Southeast Asia.
- Boundary conditions action: Effectiveness decreases at a distance of more than 20 meters from the device.
Consideration all factors when planning
Competent planning implementation of mist coolers requires accounting for many factors, starting from climatic conditions in the region and ending with specific events. It is important not only to choose the optimal type of cooler but also to correctly place the relatively main zones accumulating people and obstacles on site. Climatic conditions UAE can significantly influence on effectiveness work system.
Choice necessary equipment
- Type device: Choice between stationary and mobile models depending on the needs of the event and its budget.
- Performance and compatibility: Assessment effectiveness of the work system on a specific area, determined capacities device.
- Energy efficiency: Analysis consumption resources each device for choice optimal by ratio price/quality and impact on the surrounding environment.
Exact placement for maximum effectiveness
- Determination zones maximum concentration people: Placement coolers in places greatest accumulation participants event and guests.
- Influence wind conditions: Accounting direction and force wind for optimization distribution fog.
- Connection to resources: Providing easy access to water and electrical communications.
Strategies installation and settings
To make the coolers work with maximum effectiveness, it is necessary to follow recommendations on their installation and settings.
Study conducted in the 2021 year, confirmed that the correct settings system allowed an increase in its effectiveness by 20%.
Step-by-step guide on installation
- Preparatory works: Adequate preparation place installation equipment for providing safety and stability.
- System connection: Installation of reliable water and electrical connections according to technical diagrams device.
- Start tests: Testing system before starting its full operation with the goal of identifying malfunctions and their immediate elimination.
Subtleties settings equipment
- Regulation pressure water: Optimization pressure guarantees the creation of necessary size drops for effective cooling.
- Automation work: Settings timers and sensors for automatic on and off system depending on time day and temperature air.
Practical use during events
In the period conducting sports events, operation mist coolers require special attention for providing uninterrupted operation devices. It is necessary to consider many factors, including weather conditions and the number of participants.
Control and monitoring work
- Systematic control temperature: Constant monitoring of temperature near devices and in most zone action systems for prompt correction settings if necessary.
- Settings modes operation: Change intensity spraying depending on external climatic changes.
Accounting influence weather conditions
- Response to high humidity: Settings must be corrected to avoid oversaturation air moisture and reduce the likelihood of increased level of discomfort.
- Adaptation to wind loads: Possibilities re-settings or relocation equipment for minimizing losses in its effectiveness when changing direction wind.
Support equipment and measures safety
Investment in quality technical maintenance mist coolers not only extends the term of their service but also prevents the occurrence of potential problems.
In 2019, a study showed that regular technical maintenance reduces the likelihood of breakdowns by 30%.
Key aspects maintenance
- Maintenance filtering systems: Frequent airing and replacement filters for maintaining maximum performance devices.
- Check all connections: Assess the reliability of water and electrical connections to prevent leaks and failures in work.
- Diagnosis equipment: Proactive checks devices on likely malfunctions or wear to avoid emergency repairs during an event.
Principles ensuring safety
- Training personnel: Conducting training for employees on work with coolers, as well as training first aid in case of accidents related to operation equipment.
- Fencing zone equipment: Installation of protective barriers around systems cooling to prevent access to unauthorized persons and protect from accidental damages.
Success stories: Examples from practice
Most impressive are examples of successful application of mist coolers at the largest sports events at the world level. Among such cases can be noted the Olympic games in Tokyo 2020 and the championships of world football. At each of these events, despite a significant increase in temperature air, installations could maintain comfortable conditions for all present, which highly valued organizers and participants.
For example, at an average temperature of 35 degrees Celsius in the UAE, the temperature in arenas decreased to a comfortable 21-23 degrees, which provides quite acceptable conditions for conducting competitions.
