Problems solved by technology

The single-effect absorption type refrigeration device is used to obtain cooling capacity with a higher evaporation temperature, but it cannot obtain cooling capacity at a lower evaporation temperature when the temperature of the heat source is limited, while the multi-stage absorption refrigeration device can produce Takes cooling capacity at lower temperatures, but its performance at higher evaporating temperatures is much lower than traditional single-effect absorption refrigeration devices

Abstract

The invention discloses a single-efficiency absorption type refrigerating device with an expander-compressor, comprising a generator, a preheater, a rectifier, a condenser, a second throttle valve, an evaporator, an expander-compressor, an absorber, a solution pump, a solution heat exchanger, a fourth throttle valve and two middle heat exchange parts, wherein the generator, the preheater, the rectifier, the condenser, a first middle heat exchange part, the second throttle valve, the evaporator, the expander-compressor, the absorber, the solution pump and the solution heat exchanger are sequentially connected; the generator, the second middle heat exchange part, the solution heat exchanger, the fourth throttle valve and the absorber are sequentially connected; a gas-phase outlet of the first middle heat exchange part, the preheater, the expander-compressor and the absorber are sequentially connected; and a gas-phase outlet of the second middle heat exchange part, the expander-compressor and the absorber are sequentially connected. In the invention, work produced by the device is utilized to compress steam at the outlet of the evaporator to improve the working pressure of the absorber so as to ensure that the device can prepare cold quantity having a higher grade than that prepared by a traditional single effect absorption type refrigerating device.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and relates to a single-effect absorption refrigeration device and its system, in particular to a single-effect absorption refrigeration device with an expansion compressor. Single-effect absorption refrigeration plant for pressure and lowering refrigeration temperature. The device is especially suitable for a single-effect absorption refrigeration device that uses low-grade heat energy to produce low-temperature cooling capacity. Background technique [0002] Since Carl, a Frenchman, invented the continuous absorption refrigerator in 1860, the absorption refrigerator has been occupying an important position in the market. In recent years, as environmental problems such as the greenhouse effect and the destruction of the ozone layer have increasingly serious impacts on humans, and refrigeration systems consume too much electricity, people have paid more and more attention to the use of cle...
