Where is the economy?

How the savings is generated?

Using the adiabatic pre-cooling panel “Smart cooling ™” can significantly reduce the temperature of the air entering the air conditioning and cooling unit. As a result, in the hot weather the unit requires to expend much less power for cooling to a predetermined temperature.

Saving reached by lowering electro energy consumption is meaningful, because cooling and conditioning units occupy substantial part in overall electric energy consumption of building.

Industrial energy saving, adiabatic (evaporative) cooling

We show it on an example of Schneider Electric – one of our customers – how the savings is generated.

Each manufacturer of air conditioning and cooling units provides information on the performance of their systems. This information is available in the form of standardized tables, which state what cooling capacity (kW / h) the unit is capable to produce under certain ambient air temperatures, and how much power it spends on this (kW / h). Regardless of the manufacturer, there is a relationship – the higher is the outside temperature of air that enters the air conditioning system, the greater is the required cooling capacity. Consequently, the greater the power consumption is.

Below are given the necessary cooling capacity and energy consumption in hot weather before and after the use of the adiabatic pre-cooling panel “Smart cooling ™” on the example of the air conditioning and cooling unit Schneider Electric.

We analyze data of the air conditioning system YCAS 0475EB (covered with a red horizontal line in table) at ambient air temperatures 20°C and 38°C. 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 adiabatic pre-cooling panel “Smart cooling ™” the temperature of the air entering the air conditioning and cooling unit Schneider Electric was lowered to 25°C. Based on the data provided in the Table of 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 44,9kW / 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).

Industrial cooling capacity and energy consumption, adiabatic (evaporative) panel

The installation of the adiabatic pre-cooling panel B“Smart cooling ™” solves the problem of lack of cooling power and significant savings is generated by reducing energy consumption. In our example, after installing the adiabatic cooling system, Schneider Electric saves 44,9 kW / h every hour. It is 359 kW / h per day and 7 184 kW / h per month for this unit.
