Energy Efficiency

Energy efficiency is the goal to reduce the amount of energy required to provide products and services. Improvements in energy efficiency are generally achieved by adopting a more efficient technology or production process or by application of commonly methods to reduce energy losses. De Lorenzo has designed different trainers for this purpose to give the user the possibility to perform practical experiments on real systems. The first one consists of the study of the energy efficiency in the control of electric motor supported by a hydraulic circuit, an inverter, a PLC, pressure and flow sensors/solenoid valves and a network analyzer with interface module. The other two are developed to simulate, using real components, air compressor, air conditioner and fan. The final user can study the energy efficiency of the latter trainers as a function of different operating conditions and different components and are supplied with SCADA software for supervision and data acquisition. These trainers are recommended for high schools and first years of university.

ENERGY EFFICIENCY AIR CONDITIONER/FAN TRAINER

This trainer has been developed to simulate a large number of operating conditions of the most common installations using air conditioners and fans.
It allows studying the energy efficiency of the system as a function of different operating conditions and different components.
Complete with experiment manual and software.
TRAINING OBJECTIVES
• To prepare the professionals with knowledge and attitude for rational use of energy.
• To evaluate the aspects related to the energy efficiency in industrial consumers.
• To get knowledge to reduce the electrical power wastes.
• To get knowledge to reduce costs and investments in this field.
• To experiment equipment, instruments and technologies that are currently used in the industrial plants.
• To evaluate the possibility of energy savings associated to electrical motor systems.

TECHNICAL FEATURES
The trainer is composed of the following main components:
• A workbench, complete with loads, motors and data acquisition systems. Approximate dimensions: 2800 mm x 800 mm x 1700 mm (h). • A control panel, with all the electric and electronic components arranged in an ergonomic way. • An auxiliary table for PC, bench‐top instruments and equipment like oscilloscope, multi meters, etc. • 2 Motors (conventional and high efficiency, 1.5 HP). • Load module. • Motors driving systems: frequency inverter, soft‐starter, contactor. • Driving system and protection elements such as: circuit breakers, regulators, switches, keys, lights. • Measurement system for complete power parameters. • Mechanical measurement transducers. • Programmable Logic Controller (PLC). • SCADA Software for supervision and data acquisition.
COMMUNICATION
The communication of the Multifunction Energy Meter with the PLC is made through a serial interface with Mod Bus protocol and all the parameters (historical, time curve, etc.) are shown and monitored on a suitable window of the supervision software.
Also the selection of the motors drive system is made through the supervision software.
The PLC controls the driving systems, collects the parameters from the sensors, the transmitters and the data acquisition devices through digital input/outputs and Mod Bus port communication and communicates with the supervision software through Ethernet.
SYSTEM OPERATION
The student has the possibility to easily select which motor (conventional or high efficiency) will be coupled to the load.
The motor is driven by:
• Frequency inverter or
• Soft start key or
• Direct start by contactors intercalated and controlled by the user through the supervisory software.
