Problems solved by technology

The heating part of the generator refers to the pipeline at the connection between the generator and the liquid storage tank. At present, the heating part of the pipeline of the generator is generally heated by coiling an electric heating tube outside the pipeline. The traditional heating mechanism has the advantages of low price and simple installation. But there are also significant defects: easy loss, low efficiency, waste of power energy, and long start-up time of the refrigeration core

Abstract

The utility model discloses a diffusion absorption type refrigerating machine core using an electromagnetic heating mode, and belongs to the technical field of diffusion absorption type refrigerating machine cores. The diffusion absorption type refrigerating machine core is characterized in that a pipeline heating part is arranged on the generator, and an electromagnetic medium-high frequency heating device is arranged on the pipeline heating part; and the electromagnetic medium-high frequency heating device comprises an electromagnetic induction coil which is annularly wound on the peripheral wall of the pipeline heating part of the generator and is connected with a medium-high frequency power supply. According to the electromagnetic medium-high frequency heating device, an electromagnetic heating mode is adopted, and the temperature of a liquid medium in the generator is increased. According to the electromagnetic heating, high-frequency current passes through an electromagnetic coil wound on a generator, so that eddy current is generated in a metal pipeline of the generator to heat the generator; the diffusion absorption type refrigerating machine core has the advantages of high heating speed, energy conservation, high energy utilization rate, high starting speed of the refrigerating machine core and difficulty in damage.

Description

technical field [0001] The invention belongs to the technical field of a diffusion-absorption refrigeration core, and in particular relates to a diffusion-absorption refrigeration core using electromagnetic heating. Background technique [0002] The diffusion-absorption refrigeration core is mainly composed of generators, condensers, evaporators, absorbers, liquid storage tanks and other main components. The heat source of the electric heating tube is used to heat the liquid in the generator that is transported from the liquid storage tank by the solution pump. A solution of absorbent and refrigerant with a certain concentration, and evaporate most of the low-boiling refrigerant in the solution. Refrigerant vapor enters the condenser, is cooled and converted into liquid (release heat), and then sent to the evaporator through the throttle, absorbs the heat in the cooled system (food in the box), and intensifies into refrigerant under evaporation pressure The vapor, the remai...
