Product number: A660/415/C/AC

A fully data acquisitioned A660 Air conditioning Laboratory Unit, with all the functionality of the A660 standard unit, but computer linked, recirculating duct and PID controller.
Allows the proportion of recirculated air to be varied and its effect upon the energy requirements for air conditioning to be investigated. Additional psychrometric measuring points supplied allow the enthalpy of two-mixed streams to be investigated.
Allows investigation of the individual and combined effects of Proportional, Integral and Derivative control of temperature and humidity and the components that are required for the process. Additional software allows the process to be computer controlled and monitored as in a Building Energy Management System.
