Problems solved by technology

[0003] Conventional single-wheel dehumidification has the following disadvantages: 1) The regeneration temperature is high, mainly using heat sources such as electric heat and steam, and it is difficult to apply low-grade heat sources such as solar energy and waste heat
2) The dehumidification capacity is limited, and sufficient moisture cannot be removed. Without the cooperation of electric refrigeration, the air supply temperature and humidity requirements of the comfortable air conditioner cannot be met.
3) Deep dehumidification needs to cooperate with electric refrigeration and air conditioning, and the structure is complex
The defects and deficiencies of this patented technology are: relying on a special heat source, the energy efficiency is not ideal, and under the standard environmental conditions in summer, it cannot reach the required range of air temperature and humidity regulation

Abstract

A two grade runner dehumidification air-conditioning device, which belongs to refrigeration dehumidification technical field and can make use of low grade heat source, includes two stage dehumidification runners, two stage heat exchanges, two heaters, an evaporative cooler, a treating fan, a regeneration fan, a motor and a belt or a gear. The motor is connected with the dehumidification runners through the belt or the gear and drives the dehumidification runners to rotate. Every dehumidification runner is equipped with two areas of a treating area and a regeneration area. The treating area of the first stage dehumidification runner is connected with the inlet of the first stage heat exchanger. The outlet of the first stage heat exchanger is connected with the treating area of the second stage dehumidification runner. The other side of the second stage dehumidification runner is connected with the second stage heat exchanger. The second stage heat exchange is connected with the evaporative cooler. The evaporative cooler is connected with the treating fan. The regeneration fan is respectively connected with the regeneration areas of the two stage dehumidification runners. Two heaters are respectively connected with the other sides of the regeneration areas of the two stage dehumidification runners. Enough temperature and humidity descending can be achieved by the invention without an electric refrigeration air conditioning.

Description

technical field [0001] The invention relates to an air conditioner in the technical field of refrigeration, in particular to a two-stage desiccant dehumidification air conditioner capable of utilizing low-grade heat sources. Background technique [0002] The rotary dehumidification technology using low-grade heat source is in line with the current general trend of energy saving, emission reduction and sustainable development. The dehumidification of the solid rotor can use a low-grade heat source to drive the drying rotor to remove the moisture in the air, making it into dry air, and then achieve the required temperature and humidity range through direct evaporative cooling, which can slow down the tense trend of power supply. In addition, the dehumidification of the rotary wheel reduces the use of chlorofluorocarbon refrigerants, and there is no CFCS problem and no greenhouse effect. It is an environmentally friendly refrigeration method. The latest research also found tha...
