In the air conditioning system with independent temperature and humidity control provided by the invention, under a general working condition, the humidity control module 16 is responsible for wet load, and the evaporation temperature of the evaporator 12 of the indoor unit of the air conditioner is above the dew point temperature of indoor air and is responsible for cold load; in extreme wet and hot conditions, the humidity control module 16 is responsible for the wet load, and the evaporation temperature of the evaporator 12 of the indoor unit of the air conditioner is below the dew point temperature of the indoor air and is responsible for the total load. When the temperature and humidity of the outdoor air meet the set requirements of indoor users, the second fan 6 can directly introduce the outdoor fresh air into the indoor, adjust the indoor temperature and humidity and increase the indoor oxygen content.
The principle of the humidity control module 16 of the present invention is: the moisture absorption material 9 adopts moisture absorption MOF (metal organic framework material) as a main material for adjusting indoor air humidity, chinese names of the moisture absorption MOF material are ZIF-8, zinc 2-methylimidazole MOF, english names are 2-Methylimidazole zinc salt, ZIF 8, molecular formula is C 8H10N4 Zn, molecular weight is 227.600797176361, moisture absorption capacity is 0.3g/g (dead weight) to 0.5g/g (dead weight), and the moisture absorption capacity of the MOF is further improved by a method for reducing self temperature of the moisture absorption MOF in the moisture absorption process. After saturation of the moisture absorption, the MOF is heated to dehydrate and regenerate, and the moisture absorption capacity can be restored again. Thus controlling the humidity of the indoor air during the working cycle of moisture absorption, regeneration and moisture absorption.
According to the invention, the temperature and humidity control is independently decoupled, so that compared with the temperature and humidity coupling control of a conventional air conditioner, the air conditioner is more energy-saving, is more suitable for the requirements of a humid and hot environment on the large-scale and high-precision performance adjustment of the air conditioner, and is more suitable for the use thermal comfort habit of a user. The conventional way is to reduce the evaporation temperature of the evaporator 12 to a temperature well below the dew point temperature to ensure that both the wet load and the cold load meet the requirements. Therefore, for all loads, the air conditioning capacity is wasted, and energy is not saved. The coupled wet load regulation function is also susceptible to excessive dehumidification. The adverse effect of the condition on the application of the air conditioner in the damp and hot area can be amplified, and the refrigeration capacity of the air conditioner is insufficient and is even greater than the defects that the refrigeration of the air conditioner is not energy-saving and electricity is more wasted.
The pipeline connecting structure of the invention is as follows: the flow direction of the refrigerant is as follows: the compressor 2 discharges high temperature and high pressure, releases heat and condenses into a supercooled liquid of the refrigerant in the outdoor condenser 4, and then passes through the throttle valve 5 to become a gas-liquid mixed refrigerant. The gas-liquid mixed refrigerant sequentially passes through the moisture absorption MOF 9 of the moisture control module 16 and the indoor unit evaporator 12 to absorb heat and evaporate into superheated gas, and then the superheated gas is returned to the compressor 2 to suck air and then compressed into high-temperature high-pressure exhaust gas.
The gas-liquid mixed state refrigerant sequentially passes through the moisture control module 16 to absorb moisture and evaporate the moisture and the indoor unit evaporator 12, so that the moisture absorption temperature of the moisture absorption MOF can be adjusted, the moisture absorption capacity of the MOF can be further adjusted, the rotation speed of the indoor fan 13 can be controlled, the refrigerating capacity of the evaporator 12 can be independently adjusted, and the user requirement of accurately controlling the indoor temperature and humidity can be met.
The module structure that the first fan 10 which can rotate positively and negatively and the electric heating wire 7 are arranged below the moisture absorption MOF of the moisture control module is beneficial to the rising of hot and humid exhaust gas of the MOF regeneration working condition and the exertion of the physical property of air in which the cool air flow of the MOF moisture absorption working condition is sunk, and is beneficial to the reduction of wind resistance of the moisture control module 16 and the energy conservation and consumption reduction. The unidirectional spring air valve 11 with a pure mechanical structure reduces the air valve cost, simplifies the motor automatic control system and increases the functional reliability of the humidity control module.
The working process of the invention is as follows: general dehumidification conditions: the first fan 10 in positive and reverse rotation blows downwards, the second fan 6 is closed, the electric heating wire 7 is closed, and the air flow in the humidity control module 16 naturally forms indoor air circulation by means of air pressure difference. The unidirectional spring air valve 11 at the indoor air return port 15 side is pushed open by indoor high-pressure air due to the fact that the air pressure near the indoor air return port 15 inside the humidity control module 16 is reduced due to the fact that the first fan 10 which is in forward rotation and reverse rotation sucks air, and indoor air is formed to enter the humidity control module 16; the one-way spring damper 11 on the side of the indoor air supply port 17 is pushed open by the air supply due to the high air pressure caused by the air supply of the first fan 10 in the forward and reverse directions, and forms the indoor air supply to the humidity control module 16.
If the indoor only has wet load, the cold load is not or very small, and the air conditioner can not be started. If the indoor side air humidity load and the cold load are large, the air conditioner is started to cool the cold load and cool the humidity control module 16. The cooling method is to absorb the heat of the humidity control module through the refrigerant heat exchange pipe section 8 and improve the moisture absorption capacity of the humidity control module 16.
After the humidity control module absorbs 16 and is saturated, the electric heating wire 7 is started, the first fan 10 which is in positive and reverse rotation blows upwards, the air flow in the humidity control module 16 naturally forms outdoor side exhaust by means of air pressure difference, at the moment, the air conditioner stops the refrigerant circulation, only the indoor fan 13 is started, and the residual cold of the refrigerant system is blown to maintain refrigeration. The cycle is repeated. The heating duration of the regeneration working condition is consistent with the utilization duration of the residual cold quantity, so that the energy-saving refrigeration can be fully realized. The unidirectional spring air valve 11 of the air inlet at the outdoor side of the humidity control module 16 is pushed open by the high-pressure air at the outdoor side due to the reduction of the local air pressure in the humidity control module 16 caused by the suction of the first fan 10 in forward and reverse rotation, so as to form the air inlet at the outdoor side of the regeneration working condition of the humidity control module 16; the unidirectional spring air valve 11 of the air outlet at the outdoor side of the humidity control module 16 is pushed open by the air supply due to the high air pressure caused by the air supply of the first fan 10 which is in positive and negative rotation, so that the heat and humidity flow discharged to the outdoor under the regeneration working condition of the humidity control module 16 is formed.
Extreme dehumidification conditions: the operation is similar to the common dehumidifying working condition, the difference is that the refrigerating capacity of the air conditioner is increased, the evaporating temperature of the evaporator 12 is lower than the dew point temperature of the indoor air by at least 3 ℃, the air conditioner dehumidifies and cools simultaneously, and the energy-saving effect is weakened at the moment.
Fresh air working condition: and when the temperature and humidity of the outer side of the room meets the indoor air parameter requirement, the second fan 6 is started to directly introduce outdoor fresh air into the room, so that the indoor temperature and humidity are regulated, and the indoor oxygen content is increased. The first fan 10 and the electric heating wire 7 are closed, and the air conditioner is switched on and off according to the indoor cold load condition.
