The working principle of the invention is as follows:
as shown in fig. 4, in the refrigeration mode, a compressor air suction port of the compressor 1 sucks low-temperature and low-pressure refrigerant gas through a refrigeration pipeline 19, the refrigerant gas is compressed into high-temperature and high-pressure refrigerant gas, the high-temperature and high-pressure refrigerant gas is discharged through a compressor air discharge port and is sent to the outdoor humidity-storing heat exchanger 5 through the four-way reversing valve 4 on the refrigeration pipeline 19, the refrigerant gas is condensed by the outdoor humidity-storing heat exchanger 5 to become medium-temperature and high-pressure refrigerant liquid, the medium-temperature and high-pressure refrigerant liquid is filtered by the drying filter 7 and then throttled by the expansion valve 8, the throttled refrigerant becomes low-temperature and low-pressure gas-liquid mixture and then flows into the indoor humidity-storing heat exchanger 9 serving as an evaporator to be evaporated, the evaporated refrigerant; in the refrigeration mode, the indoor return air is cooled and dehumidified after heat and humidity exchange is carried out on the indoor return air and the indoor humidity storage heat exchanger 9 used as an evaporator, and the cooled and dehumidified air is sent into a room by the indoor fan 10 to be mixed with the indoor air, so that the purpose of cooling and dehumidifying the room is achieved. The heat and moisture exchange between the indoor return air and the indoor moisture storage heat exchanger 9 is composed of two parts, firstly, the indoor return air and the indoor moisture storage heat exchanger 9 are cooled after sensible heat exchange is carried out, secondly, moisture (latent heat) in the indoor return air is absorbed and stored by the surface drying agent coating 18 of the indoor moisture storage heat exchanger 9, and the absorption heat generated by absorption is taken away by the refrigerant in the indoor moisture storage heat exchanger 9. Meanwhile, the outdoor air absorbs the condensation heat of the outdoor humidity-storing heat exchanger 5 serving as a condenser and then is heated, the heated air is discharged into the atmosphere by the outdoor fan 6, and the heat exchange between the outdoor air and the outdoor humidity-storing heat exchanger 5 can also be divided into two parts, firstly, the outdoor fan 6 works, the outdoor air absorbs the condensation heat of the refrigerant in the outdoor humidity-storing heat exchanger 5 and then is heated and discharged into the atmosphere by the outdoor fan 6, secondly, the moisture (absorbed and stored when serving as an evaporator) in the drying agent coating 18 on the surface of the outdoor humidity-storing heat exchanger 5 absorbs the condensation heat and then is desorbed, and the desorbed moisture is discharged into the atmosphere by the outdoor fan 6 along with the outdoor air.
Further, after the surface drying agent coating 18 of the indoor humidity storage heat exchanger absorbs enough moisture, the electric box 14 controls the four-way reversing valve 4 to reverse, the rotating mechanism 13 rotates the refrigeration module 15 for 180 degrees, so that the functions and the physical positions of the humidity storage heat exchanger are exchanged, the functions of the humidity storage heat exchanger at the same physical position are not changed after the exchange, namely the outdoor humidity storage heat exchanger 5 is still a condenser, the indoor humidity storage heat exchanger 9 is still an evaporator, and through the above switching, the whole system completes one cycle. The room air conditioner based on the humidity storage heat exchanger has the advantages that due to the adsorption effect of the drying agent coating 18, moisture in return air is adsorbed and stored by the drying agent coating 18 at the temperature higher than the dew point, no condensed water is generated in the evaporation process, the evaporation temperature can be designed to be above 15 ℃, the traditional air conditioner can dehumidify only when the evaporation temperature is lower than the dew point of the return air, the designed evaporation temperature is about 5 ℃, and the moisture in the return air is discharged in the form of the condensed water. Meanwhile, the moisture stored in the drying agent coating 18 on the surface of the outdoor humidity-storing heat exchanger 5 absorbs condensation heat in the desorption process, and the condensation temperature of the outdoor humidity-storing heat exchanger 5 can be controlled to be about 40 ℃ by adjusting the frequency of the compressor 1 and the outdoor fan 6 under the combined action of outdoor air, while the condensation temperature of the traditional air cooling room air conditioner is greatly influenced by the outdoor temperature, and the rated design condensation temperature of the traditional air cooling room air conditioner is generally above 50 ℃. The increase of the evaporation temperature and the reduction of the condensation temperature effectively optimize the energy efficiency ratio of the room air conditioner.
In the heating mode, when the compressor 1 starts to work, the compressor 1 sucks low-temperature and low-pressure refrigerant gas through a compressor air suction port through a refrigeration pipeline 19 and compresses the refrigerant gas into high-temperature and high-pressure refrigerant gas, the refrigerant gas enters a four-way reversing valve 4 through a compressor air exhaust port, the four-way reversing valve 4 sends the compressor exhaust gas into an indoor humidity storage heat exchanger 9 serving as a condenser, the refrigerant gas is condensed by the indoor humidity storage heat exchanger 9 and then becomes medium-temperature and high-pressure refrigerant liquid, the medium-temperature and high-pressure refrigerant liquid passes through a drying filter 7 and then is throttled by an expansion valve 8, the throttled refrigerant becomes low-temperature and low-pressure gas-liquid mixture and then flows into an outdoor humidity storage heat exchanger 5 serving as an evaporator to be evaporated, the evaporated refrigerant becomes low-temperature and low-; in the heat pump mode, indoor return air is heated after exchanging heat with the indoor humidity storage heat exchanger 9 serving as a condenser, the heated air is sent into a room by the indoor fan 10 and is mixed with the indoor air, so that the purpose of heating the room is achieved, meanwhile, outdoor air is cooled after releasing heat of a refrigerant by the outdoor humidity storage heat exchanger 5 serving as an evaporator, the cooled air is discharged into the atmosphere by the outdoor fan 6, and moisture in the outdoor air can frost on the surface of the outdoor humidity storage heat exchanger 5 in a long-time working process. When the surface of the outdoor humidity-storing heat exchanger 5 has a frosting trend, the electric box 14 controls the four-way reversing valve 4 to reverse, the refrigeration module 15 rotates the refrigeration module 15 by 180 degrees by the rotation mechanism of the refrigeration module 15, so that the functions and the physical positions of the humidity-storing heat exchanger are exchanged, the functions of the humidity-storing heat exchanger at the same physical position are not changed after the exchange, namely the outdoor humidity-storing heat exchanger 5 is still an evaporator, the indoor humidity-storing heat exchanger 9 is still a condenser, and the whole system completes one cycle through the above switching. The traditional heat pump outdoor heat exchanger can only stop heating for defrosting after frosting, but the room air conditioner provided by the invention realizes that the outdoor humidity storage heat exchanger 5 does not frost and the heating process can be continuously carried out by reversing when the outdoor humidity storage heat exchanger 5 has a frosting trend.
