Problems solved by technology

However, the solution regenerator in the system needs to consume heat energy. The way the heat energy is provided is extremely important to the energy consumption of the entire system. Currently, the existing solutions use solar energy as a heat source, and solar energy is an unstable energy source that requires assistance. A heat source whose energy consumption has the potential to offset energy savings from solution dehumidification

Embodiment Construction

[0014] The specific implementation manner of the present invention will be described below in combination with specific examples.

[0015] As shown in the drawings of the description, the dehumidified dilute solution first passes through the first solution filter 18a, and then directly enters the absorber 2 of the absorption refrigerator after exchanging heat with the dehumidified concentrated solution, and absorbs the absorption heat of the low-pressure refrigerant vapor , and then enter the solution regenerator 4 to absorb the condensation heat of the high-pressure refrigerant, and complete the concentrated regeneration process under the action of the airflow of the dehumidification induced draft fan 16. The regenerated concentrated solution is filtered by the second solution filter 18b and stored in the concentrated solution tank 19. The concentrated solution tank plays the role of storing the concentrated solution and coupling the heat and humidity load of the absorption re...

Abstract

The invention provides a temperature and humidity independent control air conditioning unit based on absorption refrigeration. According to the unit, heat can be effectively dissipated by means of an absorption refrigerator absorber and a condenser, and concentration and regeneration of dilute solutions obtained by dehumidifying solutions are achieved. On the basis that cooling water and cooling air are provided through absorption refrigeration, temperature and humidity independent control of indoor air supply can be effectively achieved, and meanwhile refrigerating performance of an absorption refrigerator and quality of supplied air can be greatly improved compared with traditional cooling and dehumidification.

Description

technical field [0001] The invention belongs to the field of air-conditioning units, and in particular relates to a temperature-humidity independent control air-conditioning unit based on absorption refrigeration, which can realize the recovery and utilization of absorption heat and condensation exhaust heat. Background technique [0002] The absorption refrigerator can make full use of industrial waste heat, and it uses water as a refrigerant, which will not cause damage to the ozone layer and the greenhouse effect. However, due to the technical characteristics of the absorption refrigeration machine "using heat to generate cold", its refrigeration coefficient is much lower than that of the electric compression refrigeration. Every year, a large amount of heat energy is discharged in vain through the cooling tower, and a large amount of cooling water resources are consumed. [0003] The temperature and humidity independent control system, with the help of solution dehumidi...
