Abstract

The invention provides an energy-saving and dehumidifying system of a screw refrigerator, and relates to the technical field of industrial dehumidifying and energy saving, in particular to an energy-saving and dehumidifying system of a screw refrigerator. A subcooler (10) is arranged between a dehumidifying rolling wheel (3) and a main fan (4). A screw refrigerating compressor (8), condensing agent (9), the subcooler (10), a liquid reservoir (11), a first throttle valve (14) and a second throttle valve (15) are connected to a loop of one end of an evaporator (2) sequentially. An economizer (12) is arranged at the connection of the liquid reservoir (11) and the second throttle valve (15). The subcooler and the economizer are adopted in a screw-type compression refrigeration circulation subsystem to reduce energy consumption of a rear heater and increase energy efficiency ratio of the refrigeration circulation system, so that entire dehumidifier system energy consumption is obviously reduced, system capacity is also significantly reduced, and the purposes of energy saving and emission reduction are achieved.

Description

Technical field: [0001] The invention relates to the technical field of industrial dehumidification and energy saving, in particular to an energy-saving dehumidifier system of a screw refrigerator. Background technique: [0002] The quality of painting work is related to many factors, and depends to a large extent on the air humidity during construction. Excessive relative humidity during construction may cause condensation on the painted surface. Coating on a dewy surface will cause corrosion of the material and reduce the bonding force of the coating. High humidity during drying of the coating can also impair the properties of the coating, e.g. prolonged drying time, whitening of topcoats, delayed chemical reaction of two-component coatings. [0003] In order to improve the quality of coating process, industrial dehumidifiers are usually used to dehumidify and dry the ambient air. Commonly used industrial dehumidifiers on the market mainly include refrigerated dehumidifi...
