Evaporative cooling uses evaporated air to cool the room. The evaporative cooler, also known as the swamp cooler is composed of three main components: a cooling pad, a fan and a motor.
The operation is straightforward. There is a pump inside the evaporative cooling system that circulates the water from the reservoir onto a cooling mat. The pad then becomes moist. Also within the cooler is a fan that draws air in from the outside and passes through the wet pad. The evaporative cooling pads act as a filter to cool the air.
When you are looking at evaporative cool systems, two temperatures should be considered. These are:
The Dry Bulb Temperature – This is the natural temperature of the surrounding air, which we usually measure using a thermometer.
The Cold Bulb Temperature – It is the temperature at which water evaporates.
It takes energy to convert water from liquid to vapor. The majority of this energy comes from the air. The cooler’s air gives off heat energy, which is used to evaporate the water. The temperature of the coolant is decreased and the water is distributed to the environment. You should know that the temperature of the water doesn’t influence the cooling created by the evaporation.
Humidity is an essential factor that allows evaporative coolers to work effectively. Evaporation is only possible when the humidity level in the air falls below 100 per cent. The greater the effectiveness of evaporative coolant, the lower it will be. The way to measure the potential for effective evaporative heating is by comparing the wet bulb temperature to the ambient air temperature. These two indicators will be used to calculate relative humidity.
How About Evaporative Chills?
One major difference between a portable or fitted evaporative chiller and one that is portable or fitted is that the latter doesn’t include exhaust hoses, condenser or box outside. They differ from air conditioners because they do not provide refrigerant water’ but instead ‘cooled air.
Evaporative Cooling is appealing because of its amazing cost-efficiency. This allows you to lower your running costs by as high as 90%. Also, it is the most sustainable solution on the market.
How Will You Maximize Your Evaporative Cooling Performance?
To ensure efficient evaporative cooler operation, you must make sure each cooling pad has been completely saturated. You also need to make sure the fan and motors are appropriately sized to provide the necessary airflow.
It is critical to partner with a skilled supplier who is familiar with the needs of your industry, such as reducing downtime or ensuring that installation, and subsequent commissioning, are carried out without contamination.
Evaporative cooling might not always be the right solution for you. It could even be the wrong one for you depending on your industry, location or environment. You should not use evaporative cooling in the following ways:
- They can’t be used inside closed or unventilated areas as they depend on fresh, clean air to function.
- These containers were filled with water. If they are used in unventilated spaces, they will only increase humidity, making the area damp, and possibly causing mould.
