Energy ADE class

Definition

GenericEnergyConversionSystem

Energy conversion system which cannot be represented by specific class inherited from AbstractEnergyConversionSystem.

Boiler

Closed vessel in which water is heated.

ElectricalResistance

Resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it.

CombinedHeatPower

Heat engine or power station generating electricity and useful heat at the same time.

HeatPump

A device that transfers heat from a colder area to a hotter area by using mechanical energy, as in a refrigerator.

MechanicalVentilation

A building ventilation system that uses powered fans or blowers to provide fresh air to rooms when the natural forces of air pressure and gravity are not enough to circulate air through a building.

HeatExchanger

A device for transferring heat from one medium to another.

AirCompressor

A device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurised air (i.e., compressed air).

Chiller

A machine that removes heat from a liquid via a vapour-compression or absorption refrigeration cycle.

PhotovoltaicSystem

System converting solar energy in electricity.

SolarThermalSystem

System converting solar energy in heat (hot water).

PhotovoltaicThermalSystem

Hybrid photovoltaic and solar thermal system.
