Abstract

The purpose of this paper is to present the automation of a solar adsorption refrigeration system powered by a parabolic trough concentrator. This automation consists of the introduction of some adequate components such as solenoid valves, sensors (pressure, temperature and level) and pumps, which will be piloted by a programmable logic controller. Besides, to produce the electric energy necessary to the working of this refrigeration system and therefore to make it totally autonomous, a second system has been designed; it is composed of a parabolic dish reflector and a turbine coupled to an alternator that converts the mechanical work into electricity. Furthermore, in order to store the excess thermal energy delivered by the concentrator, a subsystem constituted of a pump and a supplementary reservoir is integrated to the main refrigeration system; the stored heat could serve to a domestic use. In addition to entire autonomy purpose of the unit during cold production, the simulation results showed that the proposed automation could enhance the system performance.

太阳能吸附式制冷系统的自动化

本文的目的是介绍一个太阳能吸附制冷系统的自动化驱动的抛物线槽聚光器。这种自动化包括引入一些适当的组件，如电磁阀、传感器(压力、温度和液位)和泵，这些将由可编程逻辑控制器进行控制。此外，为了产生制冷系统工作所需的电能，从而使其完全自主，还设计了第二个系统;它由一个抛物面反射器和一个涡轮组成，再加上一个将机械能转换成电能的交流发电机。此外，为了储存由集中器输送的多余热能，在主制冷系统中集成了一个由泵和辅助蓄热器组成的子系统;储存的热量可以供家庭使用。仿真结果表明，所提出的自动化方案能够提高系统的性能，同时也实现了机组在冷生产过程中的完全自主。
