Abstract :
The success of the `Monergy´ campaign has led to an improved level of energy awareness in many industries. The level of good housekeeping and the standards of thermal insulation have increased, and many heat-recovery schemes using heat exchangers have been installed. For further improvements to be made more sophisticated techniques are required and the efficient use of industrial heat pumps, when correctly applied, is for many industries the most cost-effective remaining option. Heat pumps often also carry other added benefits, such as easier process control and improved product quality. The author briefly describes mechanical-vapour-compression heat pumps and goes on to discuss rules for application and the various components of heat pumps. The author discusses three applications, i.e. dehumidifiers, malt kilns, and malt-whisky distillation
