按照制造厂家的规范来合理运行和维护机械设备是使其正常且长寿命运行的关键因素,而这一点常被忽视。虽然吸收式制冷机采用的制备冷水技术与常见的蒸汽压缩循环不同,但如果合理地运行和维护能成功地应用于相当多的领域。所需的维护次数可能比蒸汽压缩循环频繁,但通常要相对简单一些。 本文的目的是简述吸收式制冷机的运行,以便于了解如何在设计寿命内乃至设计寿命后通过较简单的维护保持机组以最高效率运行。 让我们从定义开始,燃气制冷设备通常定义为使用替代能源的、非电驱动的制冷产品,这包括吸收式制冷机、发动机驱动式制冷机和成套干燥机组等,它们都通过燃烧天然气来驱动设备。 某些燃气制冷技术,如在吸收式和干燥机组中所用的,使用热能;而发动机驱动式制冷机将热能转换为机械能后再来驱动压缩机。 目前燃气制冷市场中大部分是吸收式的系统,应该指出的是:除了吸收式制冷之外燃气制冷还包括了另外几项HVAC技术,然而从制冷机的运行和维护来看,它们之间各有异同。
It is often overlooked that proper operation and maintenance of machinery and equipment according to the manufacturer’s specifications is a key factor in their normal and long-life operation. While absorption chillers use different techniques for preparing cold water than the usual vapor compression cycles, they can successfully be used in a wide range of applications if properly operated and maintained. The number of maintenance required may be more frequent than the vapor compression cycle, but usually it is relatively simple. The purpose of this paper is to outline the operation of the absorption chiller in order to understand how to operate the chiller with maximum efficiency during its design life and even after its design life. Let’s begin by definition, gas-cooled equipment is often defined as non-electrically driven refrigerating products that use alternative sources of energy, including absorption chillers, engine-driven chillers and complete sets of dryers, all of which drive the equipment by burning natural gas . Some gas-fired technologies, such as those used in absorption and drying units, use thermal energy; and engine-driven refrigerators convert heat energy into mechanical energy and then drive the compressor. At present, most of the gas refrigeration market is an absorption system. It should be pointed out that gas cooling besides absorption refrigeration also includes several other HVAC technologies. However, in terms of operation and maintenance of the refrigerator, Similarities and differences.
