Optionally, a circulation fan is disposed in the airflow chamber 110 at a position corresponding to the indoor air outlet 102. Therefore, negative pressure is provided through the operation of the circulating fan, indoor airflow can better enter the airflow cavity 110 through the indoor air return opening 101, is dehumidified and heated and then blows out the indoor airflow, and the circulating fan is arranged at the position of the indoor air outlet 102, so that the air supply distance of the airflow blown out through the indoor air outlet 102 is longer, the circulation of the indoor airflow is accelerated, and the uniformity of indoor temperature is improved.

Optionally, first condenser 220 blocks the flow surface of airflow chamber 110, so that the airflow flowing through airflow chamber 110 can completely pass through first condenser 220 when flowing through first condenser 220, the contact area between the airflow and first condenser 220 is increased, the heat exchange efficiency is increased, the heating effect of the airflow is improved, and the drying effect is further improved.

In some embodiments, referring to fig. 2, the first refrigerant circulating system further includes: a first conduit 230 and a second conduit 240. The output end of the first condenser 220 is communicated with the input end of the indoor evaporator 200 through a first pipe 230; the output end of the first condenser 220 is communicated with the input end of the outdoor evaporator 210 through a second pipeline 240; the refrigerant in the first condenser 220 can flow to the indoor evaporator 200 and the outdoor evaporator 210 through the first line 230 and the second line 240, respectively, to absorb heat by evaporation. In this way, the output end of the first condenser 220 in the first refrigerant circulation system is respectively communicated with the indoor evaporator 200 and the outdoor evaporator 210 through the first pipeline 230 and the second pipeline 240, when the first refrigerant circulation system works, the refrigerant condensed and released in the first condenser 220 can respectively flow into the indoor evaporator 200 and the outdoor evaporator 210 through the first pipeline 230 and the second pipeline 240, and shares the evaporation capacity of the indoor evaporator 200 through the outdoor evaporator 210, so that under the conditions of small dehumidification demand and large heating and drying demand, the evaporation capacity of the indoor evaporator 200 is reduced, the refrigeration capacity is reduced, the first condenser 220 is better utilized to heat the air flow, and the drying effect is improved.

In a specific embodiment, the output end of the first condenser 220 has a tee 250, a first end of the tee 250 is communicated with the output end of the first condenser 220, a second end of the tee 250 is communicated with the liquid inlet end of the first pipeline 230, the input end of the indoor evaporator 200 is communicated with the second end of the tee 250 through the first pipeline 230, a third end of the tee 250 is communicated with the liquid inlet end of the second pipeline 240, and the input end of the outdoor evaporator 210 is communicated with the third end of the tee 250 through the second pipeline 240.

Optionally, electronic expansion valves are disposed on both the first pipe 230 and the second pipe 240. In this way, by controlling the opening and closing of the electronic expansion valves on the first and second pipelines 230 and 240, the flow direction control of the refrigerant is realized, and the evaporation amounts in the outdoor evaporator 210 and the outdoor evaporator 210 are better distributed according to the dehumidification and heating drying requirements.

In some examples, when the humidity of the indoor environment is high and the indoor dehumidification demand is high, dehumidification needs to be performed on the indoor environment first, so that the electronic expansion valve on the first pipeline 230 can be controlled to be opened, and the electronic expansion valve on the second pipeline 240 is controlled to be closed, so that the refrigerant flowing out of the first condenser 220 flows into the indoor evaporator 200 to be evaporated, the refrigeration and dehumidification capabilities of the indoor evaporator 200 are improved, the flowing air flow is dehumidified more efficiently, the cooled and dehumidified air flow flows into the indoor after being heated and warmed by the first condenser 220, and fluctuation of the indoor environment temperature is reduced; when the humidity of the indoor environment is low, the indoor dehumidification demand is low, but the heating and drying demand is high, the temperature of the indoor environment needs to be increased, so that the opening degree of the electronic expansion valve on the first pipeline 230 can be controlled to be decreased, the opening degree of the electronic expansion valve on the second pipeline 240 is increased, relatively more refrigerant flows into the outdoor evaporator 210 to be evaporated, relatively less refrigerant flows into the indoor evaporator 200 to be evaporated, the evaporation capacity of the indoor evaporator 200 is reduced, and the refrigeration and dehumidification capabilities of the indoor evaporator 200 are further reduced, so that the temperature reduction range of the air flow flowing through the indoor evaporator 200 is reduced while the indoor environment is dehumidified, the dehumidified air flow is better heated when flowing through the first condenser 220, the indoor temperature improvement efficiency is improved, and better drying is performed; when the indoor air is dry and no dehumidification is needed, the electronic expansion valve on the first pipeline 230 may be controlled to be closed, and the electronic expansion valve on the second pipeline 240 is controlled to be opened to the maximum extent, so that the refrigerant completely flows into the outdoor evaporator 210 to be evaporated, and the air flowing through is heated by the first condenser 220, thereby further improving the heating effect of the air flow and the drying effect in the room.

It will be appreciated that there is a filter and a capillary tube between the output of the first condenser 220 and the first end of the tee 250, and that the filter and capillary tube are interposed between the output of the first condenser 220 and the first end of the tee 250.

Thus, by arranging the dehumidification cavity 300 in the airflow cavity 110 and blocking part of the overflowing surface of the airflow cavity 110 through the dehumidification cavity 300, airflow entering the airflow cavity 110 through the indoor return air inlet 101 can partially enter the dehumidification cavity 300 to be dehumidified by the indoor evaporator 200, and the rest part of airflow can flow to the first condenser 220 along the airflow cavity 110 to be heated, and by partially dehumidifying the return air, the cooled and dehumidified part of airflow can be mixed with the rest part of airflow which is not dehumidified, so that the temperature of the dehumidified airflow and the un-dehumidified airflow are neutralized, and then the mixture is heated by the first condenser 220 and then flows indoors, thereby improving the heating effect of the airflow, and reducing the temperature fluctuation of the indoor environment in the process of dehumidifying the indoor environment.

Optionally, the air inlet 310 is disposed on a side of the dehumidifying chamber 300 facing the indoor air return 101, and the air outlet 320 is disposed on a side of the dehumidifying chamber 300 facing the indoor air outlet 102. Thus, the airflow entering the airflow cavity 110 through the indoor air return opening 101 can enter the dehumidifying cavity 300 through the air inlet 310 without changing the flow direction, and the airflow blown out from the air outlet 320 of the dehumidifying cavity 300 can be blown out from the indoor air outlet 102 without changing the flow direction, so that the pressure loss of the airflow is reduced, the airflow in the airflow cavity 110 can more smoothly flow into the dehumidifying cavity 300, and the airflow blown out from the dehumidifying cavity 300 can more smoothly be blown out through the indoor air outlet 102.

Thus, the airflow flowing into the dehumidification cavity 300 through the air inlet 310 flows into the first flow channel 330, is cooled and dehumidified by the indoor evaporator 200, then flows into the second flow channel 340, and finally flows out of the airflow cavity 110 through the air outlet 320 again, because the airflow passes through the second flow channel 340 after being cooled through the first flow channel 330, the temperature of the airflow circulating in the first flow channel 330 is higher than that of the airflow circulating in the second flow channel 340, and the first flow channel 330 and the second flow channel 340 are adjacently arranged, the airflow circulating in the second flow channel 340 with lower temperature can recover the heat of the airflow circulating in the first flow channel 330 with higher temperature, preheat the dehumidification airflow in the second flow channel 340, and the preheated airflow flows out of the airflow cavity 110 through the air outlet 320 and then flows to the first condenser 220 for heating, thereby improving the heating effect of the airflow and reducing the waste of heat, the energy consumption is reduced.

Alternatively, the area of the upper or lower side of the first flow passage 330 is greater than or equal to ten times the area of the flow surface thereof. Thus, since the lower surface of the first flow channel 330 is adjacent to the upper surface of the second flow channel 340, or the upper surface of the first flow channel 330 is adjacent to the lower surface of the second flow channel 340, the area of the upper surface or the lower surface of the first flow channel 330 is greater than or equal to ten times the area of the flow surface, which can increase the contact area between the first flow channel 330 and the second flow channel 340, thereby improving the heat exchange efficiency between the first flow channel 330 and the second flow channel 340, and enabling the air flow flowing through the second flow channel 340 to more efficiently recover the temperature of the air flow flowing through the first flow channel 330.

Alternatively, the area of the upper or lower side of the first flow passage 330 is equal to ten times the area of the flow surface thereof. In this way, the contact area between the adjacent first flow channel 330 and the second flow channel 340 is large, and the sizes of the first flow channel 330 and the second flow channel 340 in the rectangular structure are moderate, so that the arrangement of the first flow channel 330 and the second flow channel 340 is facilitated while the heat exchange efficiency between the first flow channel 330 and the second flow channel 340 is improved.

In some specific embodiments, as shown in fig. 6 and 7, the air outlet end of the first flow channel 330 is communicated with the air inlet end of the second flow channel 340 through a dehumidification air channel 350, and the indoor evaporator 200 is disposed in the dehumidification air channel 350, so that the air flowing through the dehumidification air channel 350 exchanges heat with the indoor evaporator 200 for dehumidification. Therefore, the air flow in the first flow channel 330 flows into the dehumidification air channel 350 through the air outlet end of the air flow, exchanges heat with the indoor evaporator 200 arranged in the dehumidification air channel 350 for dehumidification, then flows into the second flow channel 340 through the air inlet end of the second flow channel 340, exchanges heat with the air flow circulating in the first flow channel 330, recovers the heat of the air flow circulating in the first flow channel 330, and enables the heat exchange and dehumidification of the air flow to be carried out in independent air channels through the dehumidification air channel 350, so that the influence of the air flow heat exchange on dehumidification is reduced.
