The environmental controller can be of several types. Its user interface can be digital or analog and may include rate indication, data logging, and totalizing. Some are network-ready, web-enabled, or computer-programmable. Digital controllers may contain integral software, while other controllers are designed to mount on a DIN rail or rack. Some are stand-alone devices, with a full casing and integral interface.
Integrated production system technology
Integrated production system technology for environmental controllers requires a coordinated approach by all actors in the production chain. The controller must maintain core functionality to manage environmental conditions in a single tunnel, including irrigation valves, curtain motors, exhaust/circulation fans, solar thermal fans, and analog inputs for soil and air thermocouples and moisture sensors. Moreover, it should incorporate ladder logic software for controlling heating and cooling processes, thereby reducing over-cycling and maximizing energy efficiency.
Computer-programmable
A computer-programmable environmental controller is a device that controls energy equipment, such as HVAC systems, heat pumps, boilers, and chillers. These controllers install computer hardware into the system that interfaces with the environmental energy equipment’s control circuits. These devices typically consist of a keyboard, an analog-to-digital converter, and interconnect wiring. They can also be outfitted with a temperature sensor, which monitors the temperature of the environmental environment.
Web-enabled
A Web-enabled environmental controller is an online interface that allows users to configure the device and control it remotely. Unlike the traditional controller, web-enabled environmental controllers allow for almost limitless control and customization. You can program individual variables such as air flow or temperature to emulate the conditions of a specific location. All of these variables can be displayed on a graph that you can easily read. This enables you to completely control the environment at any time.
Network-ready
An environmental controller is a machine-controlled device that can regulate various environmental factors. They are typically used for control of processes in workspaces and offices, as well as in chambers for testing purposes. Environmental controllers can accept inputs from a wide variety of sensors and instruments. They can also integrate with other devices, such as air handling and variable-volume units and roof-top and fan coil units. Some are also capable of sending and receiving commands using industrial fieldbus protocols.
Cost-benefit analysis
A cost-benefit analysis can be used to evaluate the potential benefits and costs of an environmental controller. This method is based on data-driven decision-making. The cost-benefit analysis framework differs according to the type of organization and decision. However, it helps to define the costs and benefits associated with a particular decision. In some cases, the analysis will show a net benefit for an organization. In other cases, it may be beneficial to rethink the decision.
