Question

new way to improve refrigeration cycle (unique way)

Answer 1

Improvement of refrigeration cycle depends on the COP of the cycle .

As we know that COP ofAir refrigeration system, which works on Bell Coleman cycle depends on heat absorbed and workdone on system. Either heat absorbed is to be increased or workdone on the system is to be reduced in order to have higher COP. Better option is to reduce workdone on the system. It depends on design of compressor and condensor.

In case of COP of AC system, ( which is simultaneous control of temperature, humidity, air quality and air motion) other parameters also will come into pitcture.
like area of the room, oreintation of room, application, seating capacity, equipment used in the room, latent heat load, sensible heat load, outside condtions like DBT, WBT,humidity etc., design condition, by pass factor of heating or cooling coil, inflitration, season, volume of the air inhaled per minute, type of AC sysem installed like split AC or Window AC, Method of AC like cetnral AC system etc.,.
However, main concentration is to reduce workdone on compressor. Latest techniques are addition of nano particles, and use of heat pipes.The use of heat pipes as heat exchangers (evaporator and condensator) could drastically improve COP.

Also introduction of diffuser will reduce the compressor work and enhance the COP.
