‘Smart cooling™’ intelligent pre-cooling system significantly reduces temperature of the air entering conditioning unit
In hot weather, the unit uses much less power to cool air to a predetermined temperature than it would if the panels were not used alongside existing air conditioning or cooling unit.
Air conditioning and air cooling units are typically the largest consumers of electricity in commercial buildings, therefore, by substantially reducing electrical consumption, significant financial savings can be made.
Here is an example of how one of our customers, Schneider Electric, made both financial and environmental savings.
Air conditioning and cooling unit manufacturers provide information on the performance of their systems. This information is available in the form of standardized tables that state what cooling capacity the unit is capable of achieving under certain ambient air temperatures, along with how much power is used in kW / h.
Regardless of the manufacturer, there is a common relationship; the higher the temperature of air entering the chiller system, the greater the required cooling capacity. Consequently, the higher the power consumption will be.
Below is the necessary cooling capacity and energy consumption in hot weather, before and after the use of the ‘Smart cooling™’ adiabatic system using the Schneider Electric air conditioning and cooling unit as an example.
We analyzed the cooling capacity and energy consumption data of the YCAS 0475EB air conditioning system at ambient air temperatures of 20°C and 38°C. This is shown as a red horizontal line in table below. Following the data from the table we get the following indicators of cooling capacity and power consumption:
T = 25°C, N(cooling capacity) = 507 kW/h; N(electricity) = 104.3 kW/h
T = 40°C, N(cooling power) = 418 kW/h; N(electricity) = 149.2 kW/h
Through the use of the ‘Smart cooling™’ adiabatic system, the temperature of the air entering the Schneider Electric air conditioning and cooling unit was lowered to 25°C.
Based on the data provided in the Table provided by the manufacturer, the following parameters were obtained:
Ability to produce 89 kW/h more (about 20%) of cooling capacity based on the calculation N(T, 25°C – T, 40°C) and % N(T, 40°C – T, 25°C) / N(T, 40°C).
Saving power consumption of 44.9 kW/h (around 30%) based on the calculation N(T, 25°C – T, 40°C) and % N(T, 40°C – T, 25°C) / N(T , 40°C).
The installation of the ‘Smart cooling™’ system solves both the problem of low cooling capacity and drastically reduces energy consumption. In this example, after installing the adiabatic cooling system, Schneider Electric saved 44.9 kW/h every hour, which equates to 359 kW/h per day and 7 184 kW/h per month.
