Heat Exchanger Design and Heat Pump Efficiency

Dear Colleagues,

Maximizing energy efficiency in air conditioning technologies is one of the most promising areas for limiting energy consumption. Due to the increasing diffusion of heat pumps, the identification of solutions to increase their efficiency and to reduce the environmental impact represents very important areas in which to concentrate research efforts. In particular, a fundamental role for the performance of heat pumps is attributed to heat exchangers, used as a condenser or evaporator. Particularly relevant is research on innovative solutions to obtain more efficient, compact, and economical heat exchangers. It is especially relevant for use of new refrigerants with a reduced GWP but with flammability issues. In addition, it is interesting to evaluate solutions to improve the operating performance of heat pumps by means of improved system integration.

This Topic will include articles on, but not limited to, the following areas:

• Energy-efficient solutions;
• Heat exchanger design;
• Optimal design and optimal management of heat pumps.
