The invention relates to the field of heating ventilation air conditioners, in particular to a novel heat exchange dehumidification structure and method. By means of a self-heating principle, dehumidification and heating of outlet air by inlet air are achieved, and separate control over the temperature and the humidity can be easily achieved. According to the structure and the method, 1, single-cold-source self-heating structure and method are utilized, other energy reheating sections are not needed, the total cooling temperature difference of a dehumidification part is close to zero, and energy consumption is greatly reduced; and 2, the structure is simple, two surface cooling sections are arranged, the temperature and the humidity can be controlled separately, and the failure rate is low. Four listed structures and methods are protected, and the principle is explained with reference to the listed several structures of an A-structure plate-type, a B-structure liquid-circulation-type,a C-structure rotating-wheel-type, and a D-structure heat-pipe-type; and as long as the self-heating principle is used, the temperature and the humidity are separately controlled without reheating energy consumption, and the content is protected.

Description

technical field [0001] The invention relates to the field of heating, ventilating and air conditioning, in particular to a novel heat exchange and dehumidification structure and method. Background technique [0002] With the gradual popularization of modern thermal comfort theory, and the impact of humidity on comfort and health in high-temperature and high-humidity areas, the public realizes that humidity adjustment is crucial to the improvement of comfort. No dehumidification and no fresh air, the whole house comfortable humidity adjustment system will quickly enter to the houses of the people, [0003] From experts to the general public, they realize that the whole air system uses mixed air to solve the disadvantages of energy saving and dehumidification; traditional dehumidification solutions are easy to spread viruses and bacteria through mixed air, and it is not easy to achieve fresh air dehumidification and cooling through deep energy-saving dehumidification. If the ...

AI Technical Summary

Problems solved by technology

[0010] Disadvantage 1: Energy consumption. The principle of traditional dehumidifiers needs to heat up the air through external heat sources such as condensers when heating up in stage 2. This process will bring huge energy consumption

[0012] Disadvantage 2: Health and safety risks caused by mixed air, because as described in Disadvantage 1, traditional dehumidifiers repeatedly circulate mixed air to dehumidify, which may cause cross-infection of viruses or bacteria. The whole air system uses mixed air to solve the disadvantages of energy saving and dehumidification, which violates the Safety and health emphasized by fresh air conditioning

[0013] Disadvantage 3: It is not easy to achieve independent control of temperature and humidity. Most air-conditioning systems are mostly temperature-humidity coupling systems. If you want to achieve separate control of temperature and humidity, for example, the wind system in the radiant air-conditioning system that is becoming popular must be decoupled. There are many current methods The dual cold source form of fluorine refrigerant + water refrigerant is used, but this increases the complexity of the system, control complexity, structure complexity and pipeline installation difficulty;

[0018] Assuming that the outdoor summer air with a high temperature of 40°C passes through the outdoor fresh air outlet X4 and then passes through the air filter X1 and passes through the evaporator X6, the temperature of the air at this time drops to 14°C. During this process, a large amount of condensed water will be generated to perform the function of dehumidification. During the working principle, the temperature difference power consumption is 26°C. The air after cooling and dehumidification is too high in humidity. If it is directly transported, it is easy to condense in the pipe and the tuyere, thereby breeding bacteria; in order to avoid this situation, it is necessary to heat up the air and reduce the relative humidity. , so install condenser X7, but this process will increase subsequent power consumption
