Diffusion-absorption constant humidity control system with automatic water adding function for cultural relics showcase

Abstract

The invention discloses a diffusion-absorption constant humidity control system with a n automatic water adding function for a cultural relics showcase, and belongs to energy and air conditioners. A liquid outlet of a liquid storage tank, a generator, a condenser, an evaporator and one end of an absorber are connected in sequence, the other end of the absorber is connected with a liquid inlet of the liquid storage tank, a refrigerant gas inlet of the condenser is connected with one end of a balance pipe, the other end of the balance pipe is connected with the lower portion of the absorber, a water tank, a flow guide plate, a heating wire, an air supply pipe, a showcase and a return air pipe are connected in sequence, heat and mass are transferred via air, and the heating wire is disposed at the air supply pipe to arrive at constant temperature control; a semiconductor air water-extracting component, a water purifying component, a water collector and a miniature ultraviolet sterilizer are connected in sequence, condensate is treated before entering the water collector, and the water collector is connected with the upper portion of the water tank. The diffusion-absorption constant humidity control system for the cultural relics showcase allows the parts to be precisely controlled through a controller.

Description

technical field [0001] The invention relates to the field of energy and air conditioning, in particular to a diffusion-absorption type constant humidity control system for cultural relics display cabinets with the function of self-filling water. Background technique [0002] The display of cultural relics requires a specific temperature and humidity environment, which is generally obtained through a constant temperature and humidity air conditioning system. For independent showcases, due to their relatively small heat and humidity loads and relatively scattered and flexible layout, they are not suitable for large-scale centralized air-conditioning units to process air. Since different cultural relics have different requirements for environmental temperature and humidity, the independent display cabinet constant humidity control device needs to be able to independently set the target temperature and humidity and achieve precise control.

AI Technical Summary

Problems solved by technology

The idea of ​​using diffusion absorption refrigeration and constant humidity control in this patent is worth learning, but the structure of the system is relatively complicated, and two three-way valves are required for control, which is costly

[0004] At present, due to the humidification function of the constant humidity control system for showcases, it is necessary to design a water adding device to add deionized water regularly. However, in actual operation and maintenance, it is easy to cause humidification failure due to the negligence of the staff.
