What is a laboratory scale fluidized bed?

A laboratory scale fluidized bed is designed, constructed and tested using hot and cold air to simulate thermal storage of solar energy for building heating applications. Efficiency of heat storage and recovery and characteristics of microencapsulated PCMs for optimum performance are discussed based on the experimental results. 2. Experimental 2.1.

How to calculate instantaneous efficiency of a fluidized bed?

The instantaneous efficiency (η) of the fluidized bed as thermal energy storage media with PCM can be calculated as the ratio of recovered heat (Q R) to stored heat (Q S ), both calculated according to Equation (1), with the following Equation (2). (2) η = Q S Q R × 100

What is a fluidized bed?

Fluidized bed is an important unit operation used in many chemical processes, which allows intensified mass and heat transfer due to excellent phase contact and efficient mixing ( Mahmoudi et al., 2012 ).

What are the advantages of fluidized bed reactors?

Until now, fixed bed reactors are the state of the art for TCES systems. However, fluidized bed reactors offer significant advantages for scale-up of the system: the improved heat and mass transfer allows for higher charging/discharging power, whereas the favorable, continuous operation mode enables a decoupling of storage power and capacity.
