Under the scorching sun, taking the garden hose to the roof to cool your condensers because they have failed on high pressure. Do you know this situation?
In the Netherlands, cooling systems and their condensers are usually designed for a maximum outdoor air temperature of 35°C. In practice, however, the temperature is often higher. The condenser is often located on a flat black roof, which gives off a lot of heat. Or the system is set up between walls or behind a fence. The condenser then runs in its own warm air. In addition, climate change plays a role, making extreme temperatures increasingly common.
When the condenser can no longer dissipate heat efficiently, the efficiency decreases first. In the process, the pressure of the refrigerant in the refrigeration system increases. Eventually, the pressure becomes too high and the refrigeration system shuts down. As a result, the temperature in your cold store, freezer or building starts to rise. This can break the cold chain for products, with all its consequences. Naturally, you want to avoid this at all times. Adiabatic pre-cooling ensures that your cooling installation continues to operate optimally during temperature peaks.
What is adiabatic pre-cooling
Adiabatic pre-cooling cools the air before it enters the condenser. It does this by atomising clean, lime-free water very finely into the cooling air. The atomisation lowers the temperature, as the water quickly evaporates before reaching the heat exchanger. This relieves the cooling system and keeps it working optimally, regardless of the outside temperature. This keeps your cold store, freezer or building at the right temperature at all times.
What should you pay attention to?
Adiabatic pre-cooling can significantly improve the efficiency of cooling systems, but using water for cooling also carries the risk of legionella contamination. Therefore, our adiabatic pre-cooling systems are always equipped with a reverse osmosis system. Thanks to the reverse osmosis system, the system can moisten legionella safely at your cooling system. In addition, we atomise under high pressure. This creates fine aerosols. These follow the flow lines and evaporate very quickly. This eliminates the risk of clogging or fouling the heat exchanger.
Benefits adiabatic pre-cooling
Adiabatic pre-cooling offers several advantages. These advantages are explained in more detail below:
1. Energy efficiency
By cooling the outside air before it enters the condenser, adiabatic pre-cooling reduces the refrigeration system's workload. The refrigeration system requires less energy to achieve the desired cooling capacity. Your cooling system thus operates more efficiently and consumes less energy.
2. Cost savings
If the cooling system uses hot air for cooling, it requires more energy to cool the air. Thanks to adiabatic pre-cooling, the incoming air is cooled before it enters the condenser. The chiller uses less energy to bring this air to the desired temperature. This allows you to reduce your energy bill, especially during hot seasons when cooling systems operate more intensively.
3. Improved cooling capacity
Adiabatic pre-cooling ensures that your cooling system works optimally, regardless of the outside temperature. By using adiabatic pre-cooling in the cooling air, the cooling capacity of your cooling installation can be increased. This results in a lower load and more effective operation of the cooling installation at higher outdoor temperatures.
4. Improved lifespan
Higher thermal loads can have a significant impact on the service life of your cooling system. Resulting in accelerated wear and increased maintenance costs. Adiabatic pre-cooling reduces this load, which can contribute to a longer lifespan of your cooling system.
