This article examines the operating principle, applications, and benefits of evaporative coolers, as well as the technical aspects to consider when using them. Operating Principle of Evaporative Coolers Evaporative coolers utilize the evaporation process of water to cool the air effectively. This is based on a physical phenomenon where water evaporates and absorbs heat energy from the surrounding air, leading to a decrease in air temperature. Humidification and Heat Transfer Water evaporates when exposed to an airstream, and this process absorbs heat from the air, cooling it down. Coolers use special pads designed to maximize the surface area for water evaporation. These pads are often made of cellulose or plastic, which are hygroscopic and provide a large evaporative surface. Air flows through the pads via a fan, where it encounters water. The water evaporates, absorbing heat energy from the air, thus cooling it. Energy Consumption and Efficiency The energy consumption of evaporative coolers is significantly lower compared to traditional mechanical cooling systems because the process uses natural water evaporation and does not require substantial amounts of electrical energy. The efficiency of these systems depends on the ambient temperature and humidity. They work best in dry and hot conditions where the air’s moisture content is low, as this makes water evaporation most efficient. Operational Principle Adiabatic Cooling: Air is cooled through an adiabatic process where its temperature drops as it becomes humidified. This means that the air’s thermal energy is used for water evaporation without an external energy source. Ventilation and Pressure: In the cooler, air passes through the pads via a fan. The air flowing through the pads encounters moisture that evaporates and cools the air. The fan’s role is critical as it ensures sufficient airflow through the pads and guarantees uniform cooling. Water Circulation: In evaporative coolers, water circulates continuously. Water is pumped to the top of the pads, from where it flows down and evaporates due to the airstream. The recirculation system ensures even water distribution and optimizes the cooling process. Applications in Professional Use Evaporative coolers are widely used across various industries and other large-space cooling applications where efficient and cost-effective cooling is needed. Industrial Facilities Metal Industry: In hot factory halls where temperatures can rise extremely high, evaporative coolers provide an efficient cooling solution that helps keep the working environment tolerable and safe. Automotive Industry: Assembly lines and paint shops in car factories benefit from a cooler working environment, which improves worker efficiency and reduces errors. Food Industry: Evaporative coolers are ideal for cooling large storage and production areas where temperature control is critical to maintaining product quality. Data Centers Data centers require continuous and efficient cooling to prevent equipment from overheating. Evaporative coolers offer an energy-efficient alternative that can significantly reduce cooling costs in data centers. Using adiabatic cooling, data centers can also reduce their carbon footprint, which is increasingly important as environmental regulations tighten. Agriculture Greenhouses: Evaporative coolers help maintain optimal growing conditions, improving crop yields and growth rates. Cooler air reduces plant stress and enhances their resistance to diseases. Animal Shelters: Animal welfare improves in cooler conditions, leading to better health and productivity. This is especially important during the summer months when heat stress can negatively affect animal well-being. Advantages and Challenges Evaporative coolers offer many advantages. Advantages Energy Efficiency: Evaporative coolers use significantly less electrical energy compared to traditional cooling systems because they rely on the natural evaporation process.

The company purchased a mid-sized REX25000 model from Rex Nordic’s EcoCooler range, which has an air flow of up to 25,000 cubic meters per hour. The cooling capacity of the movable EcoCoolers is heavily based on the evaporation of cold water through a honeycomb pad. The advantages of the cooler include efficient cooling without water mist, large air flow, low energy consumption, and no installation costs. “There is a clear temperature difference in the hall when the EcoCooler is in use. Customers have praised how pleasantly cooler and fresher the air is”, says Mika Holappa, owner of Vantaa Gym. At Vantaa Gym, the REX25000 was placed on the second floor in the treatment room, from where the cooler blows into the gym through an open interior window. This way, the cooler did not need to be placed among the gym equipment or people, and the cool air spread widely in the hall as it fell down. “We really didn’t have the opportunity to acquire any other solution for our premises. We rent from the city, and in the same “hectare-sized” hall there are other businesses, so we cannot, for example, install fixed cooling solutions. At first, I thought of buying ten smaller fans scattered around the hall, but then I discovered the EcoCooler on the internet and decided to try it.” “When the sun shines strongly through the skylights, the hall has been extremely hot and, at worst, felt like “the oxygen is running out”. There is basic ventilation in the hall, but it is not sufficient in hot weather. It helps to circulate the air and push cool air down while also bringing replacement air into the room, but nevertheless, the EcoCooler has done its job. In cooler weather, I have had it on half power. When it has been warmer, the fan has been on full power.” In addition to the REX25000, Rex Nordic’s EcoCooler range includes the smaller REX14000 and the larger REX48000. They are designed for different sizes of rooms, run on standard power, and do not require fixed installation or electrical work. Water directly from the hose to the tank The REX25000 has practically been constantly connected to the water supply at Vantaa Gym, which means that cold water has been constantly flowing into the EcoCooler tank. The water has been consumed in moderate amounts relative to the benefit, and there have been no humidity problems due to the EcoCooler in the hall. The water evaporates from the EcoCooler; it does not spray or cause water mist. “In hot weather, the water is constantly on. I also tried the cooler by simply filling the tank. In that case, the tank (170 litres) used water in 8-10 hours”, estimates Holappa. The open and bright Vantaa Gym has a versatile gym with modern equipment, where professional guidance is available if desired. At Vantaa Gym, one can also purchase gym programmes as well as personal training, physiotherapy, massage, and nutrition advice. The gym also allows for boxing or focusing on stretching exercises. There is a traditional sauna in the men’s changing room and an infrared sauna on the women’s side. There is also a play area for children. “It is important for us to listen to our customers and purchase equipment according to their wishes and needs. Our gym is accessible via an app around the clock every day. One can also purchase only the services needed, even for a single visit in the middle of the night. We do not bind our customers to anything.” Vantaa Gym is located at Hosantie 2, Vantaa. Vantaa Gym Club https://vantaagym.fi
