  1. Thermal Recovery Systems www.improvair.co.uk

  2. Why are we here today? • To Develop a Working Relationship • Share information on a R & D basis In Return we offer • Carbon Reduction • Energy Savings • Cost Reduction

  3. Principal Of Operation • The system comprises of a Bespoke Extract Canopy and Duct Heat Recovery System. • The patented system comprises of a Gas to Fluid (Air to water) heat exchanger. • Heat collected is transferred into a thermal Store. • This Energy is then used to pre-heat the cold mains supply water supply to feed dish washers, conventional hot water cylinder and / or combination boiler for heating or LPHW heater batteries.

  4. Design of Heat Exchanger • The heat exchanger has been designed into the canopy and ductwork. • The heat is transferred in an inherently safe environment out side the contaminated air flow. • No heat exchangers within the canopy or ductwork – leaving no obstructions for inspection and cleaning. • No obstructions in the extract system – no effect on extract rates.

  5. Breakdown of energy use in the average Hotel /Pub.

  6. Energy Collection Graph 1

  7. Explanation of Graph 1 • Graph number 1 S1 shows a temperature elevation of 19C over 6 hours from 20C to 39C. • S2 Shows the flow temperature from the canopy to the 300lt thermal store achieving 49C over the same duration. • These temperatures have been taken from only 24kw input from the test rig.

  8. Graph Number 2

  9. Explanation of Graph 2 • Here we ran 100lt of water off to waste every 30 minutes to simulate a working kitchen. • As you can see there was a steady rise in temperature during this process. • We collected 1.83kwh per hour with an input of 24kw LPG gas burner and copper sheet collection area of only 1.28m2 on the canopy and a duct collector area of 1.1m2
