Verdicorp's Organic Rankine Cycle System
The energy puzzle:
Renewable power generation is the key piece of the puzzle that had to be solved in order for countries around the world to get off the energy addiction that the current modern society has become accustomed to.
In order to meet the challenge, Verdicorp has developed a revolutionary power generation system that will help break this addiction. It is an oil-free, highly efficient Organic Rankine Cycle system, which converts a low grade heat source and turns it into electrical energy.
Organic Rankine Cycle Systems can be described as a chiller running backward. Instead of using electrical energy to produce cooling, this system takes heat from a low grade heat source and turns it into economical electrical energy. (400/480V-50/60Hz.). This power is then phase matched to meet the local electrical grids requirements.
Verdicorp utilizes the environmentally friendly refrigerant 245fa.
A variety of configurations:
These systems can be configured in either stand alone, mobile or modular configurations. Being factory built, these units are fully constructed and tested in a controlled environment, thus increasing quality and system integrity, while at the same time being manufactured at the lowest possible cost.
Verdicorp offer a range of air-cooled, water-cooled and condenser-less models
The turbo generators operate at high efficiency, with synchronous frictionless high speed generators running on magnetic bearings. The systems integrated power electronics have been designed to deliver grid compatible power.
These generators are able to be coupled together in an Organic Rankine Cycle System in tandem without the disadvantage of oil and all of its complications. Maintenance becomes a lot simpler.
A variety of heat sources:
The Verdicorp ORC system has been designed to operate from heat sources such as bio-gas, solar thermal, geothermal, bio-mass, and industrial waste heat streams, and can operate with thermal oil,high pressure hot water or steam.
Verdicorp’s technologies are based on the globally accepted oil-free Turbocor compressor technologies:
Magnetic bearings and bearing sensors:
Composed of both permanent and electromagnets with unique, patented design for compact size and reliable high performance enables precisely controlled frictionless shaft rotation on a levitated magnetic cushion. Bearing sensors, located at each magnetic bearing, feed back rotor orbits and thrust/axial information in real time to bearing controller
Permanent-magnet synchronous motor:
Powered by PWM (pulse width modulated) voltage supply. High-speed variable frequency operation affords high efficiency, compactness and soft start benefits
Radially and axially located bearings support the rotor when the machine is not energized and prevents contact between rotor and other metallic surfaces
Shaft and impeller:
Only one major moving component acts as rotor for permanent-magnet synchronous motor. The impeller is keyed directly to shaft
Variable Frequency Drive:
IGBT (Insulated Gate Bipolar Transistor) is a bi-directional device that converts DC voltage into an variable three-phase AC voltage and vice versa. Signals from the motor/bearing controller determine the inverter output frequency, voltage and phase, thereby regulating the motor speed converts mechanical energy back into electrical energy. In the case of Power failure, this patented control scheme allows for a normal de-levitation and shutdown
Soft start module:
Significantly reduces high in-rush current at startup, providing advantages to line power systems and reducing thermal stress at the stator. The startup in-rush current is less than 2 amps vs. typically up to 1,000 amps experienced by traditional compressors in the same capacity range—truly defining soft starts
Rectifiers convert AC line power into a high voltage DC power source. Capacitors for smoothing DC power supply. DC-DC Converters for supply and isolation of high and low voltage DC voltages. Network connections for external controls and monitoring of the PWM amplifier for powering the electromagnetic bearings and the motor are microprocessor controlled.
