Optimisation of run-around coils - component development and dimensioning
Run-around coils is the only possible heat recovery solution in industries where leakage between the supply air and exhaust air must be avoided. Electricity consumption for fluid coupled batteries in the industry, however, is high compared to the overall efficiency of the system. The aim of the project is to develop solutions with corresponding selection tool that ensures higher efficiency.
The project is developing a new design basis for system solutions with corresponding selection tool that ensures higher efficiency for recycling systems with run-around coils both in relation to the electricity and heating consumption. The project will also result in the development of new, more energy efficient heating coils which in addition to be able to be used in conjunction with run-around coils could be further developed for application to heating surfaces. Development of a new selection tool that enables ventilation contractors to optimize the use of heat recovery, e.g. run-around coils, from the energy consumption and operating economy in the given situation at the customer's location, which is predicted to cause heat recovery systems with much higher efficiency than is the case today. This is true both in terms of heat recovery and the minimization of heat recovery pressure losses.
The project includes:
- Study of how the existing selection basis with the suppliers of ventilation systems for run-around coils is determined
- Development of selection tools for heat recovery
- Development of management concept for heat recovery with run-around coils that optimizes recovery from total operating economy, including the possibility of the establishment of bypass over the recycling system
- Development of heating coils for liquid coupled batteries that are more energy efficient
- Testing and documentation of the developed alternative forms of heating coils for run-around coils
Dissemination of results to advisors, ventilation contractors and suppliers.
This project has investigated the possibilites for higher system-efficiency for ventilationsystems with fluid coupled batteries eg. lowest possible energy consumption concurrent with the total annual operating costs are minimised.
This project has develop af new dimensioning tool for optimising heat recovery and heat recovery of fluid coupled batteries. New design guides for system solutions to secure higher efficiency for recovery systems with fluid coupled batteries. A performance-tool of fluid coupled batteries and a control concept.
