![]() ![]() If COP=3, 1kW electrical power will produce 3 kW of cooling at the evaporator and 4 kW of heating at the condenser. Mentioned method is considered as a traditional one in which a flow meter is needed.Ģ.0 Electrical Power Calculation/Reading:Ģ.1 Direct: reading it directly from power/energy meter.Ģ.2 Indirect: calculating it base on: P=√3*V*I*Cosɸ in 3 phases applications The COP calculation is based on the following formula:ġ.0 Thermal Power Calculation: The calculation of the thermal power of a hydraulic system is based on the mass flow rate, the heat capacity of the medium, and the temperature difference before and after heat dissipation.įor meters providing a volume flow, the mass flow is calculated according to: ![]() To do energy savings with the regulation, we have to manage the machine when the outsides factors evolve to have the lower consumption of the machine. – The outside temperature (and humidity sometimes) – The load (depends on the usage, AC, cooling, etc…) Three outsides factors that can directly impact the consumption of a chiller or a cooling unit:
