Embodiment Construction

[0027] The content of the present invention will be described in detail below in conjunction with the drawings and specific embodiments. It should be understood that the present invention is not limited to the following preferred embodiments, which are only used as illustrations of the present invention.

[0028] Such as figure 1. Shown, direct cooling type cold wind evaporator lithium bromide absorption chiller flow process of the present invention figure 1, The figure shows a single-effect lithium bromide absorption chiller. Drive the heat source to heat so that the refrigerant vapor flows from the generator 2 into the condenser 1 and is cooled by cooling water to become a liquid state. The liquid refrigerant enters the direct cooling cold air evaporator 3 for vaporization after being depressurized by the throttle valve, and the refrigerant vapor is vaporized in the absorber 4 It is absorbed by the concentrated solution from the generator 1 to become a dilute solution, an...

Abstract

The invention discloses a lithium bromide absorption type water chilling unit for a direct cooling type cold-blast air evaporator, which comprises a lithium bromide absorption type water chilling unit and a refrigerant circulator and a lithium bromide solution circulator thereof, wherein the lithium bromide absorption water chilling unit comprises a condenser 1, a generator 2, a direct cooling type cold-blast air evaporator 3, an absorber 4, a solution heat exchanger 5, a solution pump 6 and a refrigerant pump 7, and the water chilling unit is directly connected with an air conditioner air system. The lithium bromide absorption water chilling unit is characterized in that the direct cooling type cold-blast air evaporator 3 is a vacuum closed cylinder consisting of air-cooled heat transfer pipe sets 9, and air is cooled in an air-cooled manner. By adopting the invention, the contradiction between unit performance and heat source grade in the traditional lithium bromide absorption water chilling technology is eliminated, the unit performance parameter is improved, and advantages are created for continuous application of solar refrigerating air conditioners and comprehensive utilization of low-temperature waste heat and exhaust heat.

Description

technical field [0001] The invention relates to a direct-cooling cold air evaporator lithium bromide absorption chiller, more specifically, relates to a lithium bromide absorption chiller which adopts an evaporator to directly cool air. Background technique [0002] Lithium bromide absorption refrigerators use steam, hot water, heat generated by direct combustion of fuel oil / gas or other waste heat as heat sources to achieve refrigeration. Since CFCs and HCFCs refrigerants have a destructive effect on the atmospheric ozone layer, and HFCs refrigerants have a greenhouse effect. Under the current external environmental conditions of tight power supply and climate change, the lithium bromide absorption refrigerator has high promotion value. my country has become the largest producer of absorption refrigerators in the world. The development direction of lithium bromide absorption refrigerators is mainly to improve efficiency, popularize and apply them to cogeneration systems of ...
