Abstract

The invention discloses a microwave adsorption type refrigeration system and method. The system comprises an adsorption bed A, an adsorption bed B, a condenser, an evaporator and a cooler; the condenser and the evaporator are connected through a pipeline; the adsorption bed A is connected with the condenser and the evaporator through valves respectively, the adsorption bed B is connected with thecondenser and the evaporator through valves respectively, and a circulating loop is formed by connecting the adsorption bed A with the cooler through a pipeline; a circulating loop is formed by connecting the adsorption bed B with the cooler through a pipeline; microwave sources are arranged in the adsorption bed A and the adsorption bed B respectively; an adsorption working medium pair in the adsorption beds is heated by emitting microwaves through the microwave sources. According to the system, the microwaves serve as a driving heat source, and because microwave heating has the characteristics of selective heating and rapid heating, the adsorption working medium pair can be rapidly heated to a required temperature; the desorption speed is increased, so that the cycle period is shortened,and the refrigerating capacity and the refrigerating efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of adsorption refrigeration, in particular to a microwave adsorption refrigeration system and method. Background technique [0002] Traditional adsorption refrigeration systems usually use solar energy, boiler waste heat, and industrial waste heat as heat sources to drive refrigeration, but typical solar adsorption refrigeration systems have limited heat source driving temperatures, and are constrained by discontinuous and unstable solar radiation, making it difficult to stabilize and continue refrigeration. ; When the waste heat drive system is used for refrigeration, due to the low thermal conductivity of the adsorbent and the poor heat and mass transfer performance of the adsorption bed, the adsorption and desorption time is too long, the cycle period increases, and the cooling capacity decreases. [0003] Microwave heating is the process of using the energy characteristics of microwaves to heat objects. ...
