ZM6504 Efficiency in heating technology Educational Equipment Refrigerator Training Equipment

Basic principles of energy efficient heating technology with a computer-supported learning process

Features

– trainer with closed heating circuit – trainer on mobile frame – pumps, heater and convector fan, controlled via PC Learning objectives/experiments – familiarisation with a heating circuit

– familiarisation with temperature control — two-point controller — PID controller

— recording of step response – recording of fitting and pump characteristics

– energy balances – determining pump efficiency from hydraulic power and electrical power consumption

– heat transfer with convector (water-to-air heat exchanger with fan) – comparison of circulating pumps

— conventional pump — differential pressure controlled pump
