Jan Boone - Natural Refrigerants - NH3 heat pumps for hot water production
PDF document
published on 16 March 2015
Mayekawa's Jan Boone presented a case study describing an industrial bakery plant located in Mouscron, Belgium, requiring a hot water heat pump for an extension of its production capacity, which would reduce energy consumption/energy costs in order to contribute to the company's sustainability program. To produce hot water at 65°C an ammonia (NH3) heat pump was used, with a condensing temperature at 67°C corresponding with a pressure of 29.5 barg. The heat pump uses the ammonia refrigeration system condenser-heat as the heat source, giving a positive impact on the condenser load and recovering the residual heat for hot water production and process water, to provide ideal warmth and humidity for the rising of the bread-products in the plant.

Garry Shaw, John Burden - Cranswick County Foods: new industry standard in energy optimisation and refrigeration
PDF document
published on 16 March 2015
Johnson Controls worked with a leading UK food supplier, Cranswick Country Foods, to optimise a new industrial refrigeration system of the pig abattoir in Watton, Norfolk. This presentation shows that by installing Sabroe industrial refrigeration heat pump reciprocating compressors, the company was able to reduce the energy costs by £500k per year, increase the productivity by 30% and decrease the weight loss of the carcasses from 2,3% to 1,4%. This solution set a new industry standard, as it not only monitors and trends the performance of the plant, but also actively hunts for optimal set points to reduce energy usage.

José Miguel Corberán - A propane water-to-water heat pump booster for sanitary hot water production
PDF document
published on 16 March 2015
Jose Miguel Coberan investigated propane as an alternative in a water-to-water heat pump booster for sanitary hot water production. In comparison to CO2, Corberan, on behalf of the Universitat Politècnica de València, noted that at different condensation temperatures, propane had an optimal for each temperature. Corberan also said the use of hydrocarbons in this application allows for lower charges and lower displacement compressors compared to R134a and R1234yf.

Paul de Larminat - High temperature water vapour heat pump
PDF document
published on 16 March 2015
Paul De Larminat showcased the test results of Johnson Controls’ heat pump using water vapour as the working fluid. To plug a specific hole in the market, JCI teamed up with Electricité de France (EDF) to develop high pressure heat pumps for the industrial market (600kW at 90/130°C). De Larminat extolled the many virtues of using water vapour: Its low cost, excellent efficiency at high temperatures and ability to be used in closed and open loops.
