Hot water production - NH₃ heat pumps

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.
