[0001] The present disclosure relates to the technical field of air conditioning, and in particular to a continuous heating and humidifying air conditioner and a control method thereof. Background Art

[0002] With the continuous improvement of living standards, air conditioners have entered thousands of households and become one of the indispensable appliances in people's lives. As a heat pump air conditioner, the need for defrosting and humidification of the internal unit in winter has always been a bottleneck problem in the industry. For example, the defrosting stage of the external unit affects the heating of the internal unit; the internal heating process usually makes the air "drier" without humidification, which makes the user feel worse.

[0003] Since the existing heat pump air conditioners in the prior art cannot simultaneously solve the technical problems of frost on the outdoor heating unit in winter, continuous indoor heating and indoor drying, the present invention studies and designs an air conditioner with continuous heating and humidification and a control method thereof.

[0004] Public Content

[0005] Therefore, the technical problem to be solved by the present disclosure is to overcome the defects of the air conditioner in the prior art that it cannot simultaneously solve the problems of frosting of the outdoor heating unit in winter, continuous indoor heating and indoor dryness, thereby providing an air conditioner with continuous heating and humidification and a control method thereof.

The outdoor temperature and humidity sensor can detect the outdoor temperature and humidity to determine whether the outdoor heat exchanger has reached the conditions requiring defrosting and whether the defrosting has been completed. The indoor temperature and humidity sensor can detect the indoor temperature and humidity to determine whether the indoor air has reached the conditions requiring humidification and whether it needs to be heated.

[0015] In some embodiments, the position where the moisture absorption module moves to the air inlet side of the outdoor heat exchanger along the air flow is position A, and the position where the moisture absorption module moves to the air outlet side of the indoor heat exchanger along the air flow is position C;

[0016] The moisture absorption module can also move to a position between the indoor heat exchanger and the outdoor heat exchanger when neither the outdoor heat exchanger needs to be defrosted nor the indoor room needs to be humidified.

[0017] In some embodiments, the position between the indoor heat exchanger and the outdoor heat exchanger includes a B position and a D position, wherein the B position is located on the path of the desiccant module moving from the outdoor heat exchanger toward the indoor heat exchanger, and the D position is located on the path of the desiccant module moving from the indoor heat exchanger toward the outdoor heat exchanger.

[0018] In some embodiments, the air conditioner is a through-the-wall unit or a window unit, and / or the air conditioner further includes a compressor.

[0019] The present disclosure also provides a control method for a continuous heating and humidifying air conditioner as described in any of the preceding items, wherein when the air conditioner is in a heating mode and includes an outdoor temperature and humidity sensor, the control method comprises:

[0020] A detection step, detecting the outdoor temperature and humidity by means of the outdoor temperature and humidity sensor;

[0022] Control step: when the temperature on the outdoor side is lower than the first preset temperature and the humidity on the outdoor side is greater than the first preset humidity, control the desiccant module to move to the air inlet side of the outdoor heat exchanger along the air flow to dehumidify the airflow before entering the outdoor heat exchanger.

[0023] In some embodiments, when the air conditioner includes an indoor temperature and humidity sensor:

[0025] A determination step, determining whether the humidity inside the room is less than a second preset humidity;

[0036] like Figure 1-5 As shown, the present disclosure provides an air conditioner for continuous heating and humidification, which comprises:

[0037] The outdoor heat exchanger 1, the indoor heat exchanger 2 and the desiccant module 3, when the air conditioner determines that it is necessary to delay entering the defrost mode (that is, the outdoor temperature is low and the humidity is high, and there may be a risk of frosting on the outdoor heat exchanger at this time, so the desiccant means disclosed in the present invention can effectively delay the frosting of the outdoor heat exchanger), the desiccant module 3 can move to the air inlet side of the outdoor heat exchanger 1 along the air flow to dehumidify the airflow before entering the outdoor heat exchanger 1, and when the indoor air needs to be humidified, the desiccant module 3 can also move to the air outlet side of the indoor heat exchanger 2 along the air flow to humidify the air after passing through the indoor heat exchanger 2 after being heated, and then blown into the room.

[0038] The present invention provides a dehumidification module, and when the outdoor heat exchanger needs to be defrosted, it can move to the air inlet side of the outdoor heat exchanger, so that the air before entering the outdoor heat exchanger can be effectively dehumidified, and the moisture can be absorbed, so that the humidity of the air entering the outdoor heat exchanger is greatly reduced, so that the outdoor unit will not frost or frost will be delayed in the heating mode, and the continuous heating of the room can be effectively guaranteed, thereby improving the heating comfort; at the same time, the dehumidification module can also move to the air outlet side of the indoor heat exchanger along the air flow direction when the indoor air needs to be humidified, so as to transfer the hot air generated by the indoor heat exchanger to the indoor heat exchanger The air is effectively humidified and blown into the room, so that when the indoor humidity is low, the indoor air can be effectively humidified through the moisture absorption module; the present invention can not only reduce or avoid frost on the outdoor heat exchanger, but also effectively humidify the indoor side, and use the air humidity on the outdoor side to humidify the indoor, realizing the effect of an integrated structure of continuous heating-no frost-indoor humidification, and actively using the outdoor air humidity to effectively humidify the indoor, so that the present invention is more applicable, consumes less power, reasonably uses resources, and has a more compact and practical structure.

[0039] The present disclosure provides 1. an air conditioning device with an integrated indoor and outdoor heat exchanger, which has a guide rail along the periphery of the device and a solid moisture absorption module running on the guide rail.

[0040] 2. Before the unit judges that it is time to enter the defrost time T0, the solid dehumidification module runs to the front of the outdoor heat exchanger, which can delay defrosting, or the unit does not defrost to improve user comfort.

[0041] In some embodiments, the desiccant module 3 first absorbs moisture in the outdoor air from the outdoor heat exchanger 1, and then moves to the indoor heat exchanger 2 to humidify the indoor air; and / or, the desiccant module 3 includes an adsorbent that can absorb moisture, and the adsorbent can be heated to release moisture.

[0042] This is a preferred embodiment of the desiccant module disclosed in the present invention, that is, it first passes through the outdoor heat exchanger and then reaches the indoor heat exchanger. It can first absorb moisture in the air from the outdoor side to dehumidify the outdoor area, and then transport the moisture absorbed in the desiccant module to the indoor area to effectively humidify the indoor area, so that the indoor area can have moisture for humidification. The present invention can form a movement cycle process of the desiccant module, first absorbing moisture from the outdoor area-humidifying the indoor area, and then returning to the outdoor area to continue the desiccant effect; the desiccant module disclosed in the present invention preferably includes an adsorbent that can absorb moisture (preferably a solid adsorbent, such as silica gel or activated alumina), which can release moisture by heating (at the indoor heat exchanger) to humidify the indoor area.

[0043] In some embodiments, it further includes a guide rail 4, on which the moisture absorption module 3 is arranged, and the moisture absorption module 3 can be driven to move along the guide rail 4 between the indoor heat exchanger 2 and the outdoor heat exchanger 1, or the guide rail 4 can be driven to drive the moisture absorption module 3 to move between the indoor heat exchanger 2 and the outdoor heat exchanger 1. This is the preferred structural form of the air conditioner disclosed in the present invention. Through the structural setting of the guide rail, the moisture absorption module is arranged thereon and can move along the guide rail, or the moisture absorption module is fixed on the guide rail and the guide rail moves along a predetermined direction, so as to achieve the effect of transferring the moisture absorption module between the indoor heat exchanger and the outdoor heat exchanger, and complete the integrated function of outdoor anti-frost and indoor humidification.

[0044] The present invention preferably has a guide rail on the periphery of the shell for placing the solid circulation dehumidification module, and the module is driven by a motor to achieve sliding on the guide rail.

[0045] In some embodiments, an outdoor fan 51 is further included, and the outdoor fan 51 is arranged on the downstream side of the outdoor heat exchanger 1 along the air flow direction to suck the air in the outdoor heat exchanger 1. When the dehumidification module 3 moves to the air inlet side of the outdoor heat exchanger 1 along the air flow, the air is sucked by the outdoor fan 51, so that the air first passes through the dehumidification module 3 to be dehumidified and then enters the outdoor heat exchanger 1 for heat exchange; and / or,

[0046] It also includes an indoor fan 52, which is arranged on the upstream side of the indoor heat exchanger 2 along the air flow direction to blow the air toward the indoor heat exchanger 2. When the desiccant module 3 moves to the air outlet side of the indoor heat exchanger 2 along the air flow, the air is blown out by the indoor fan 52, so that the air first passes through the indoor heat exchanger 2 for heat exchange and then passes through the desiccant module 3 to be humidified, and finally enters the indoor air.

[0047] The present invention can also suck the airflow of the outdoor heat exchanger through the arrangement of the outdoor fan. When the desiccant module moves to the air intake side of the outdoor heat exchanger, the airflow can first pass through the desiccant module to be dehumidified through the suction of the outdoor fan, and then enter the outdoor heat exchanger for heat exchange after the moisture in the air is removed, thereby effectively avoiding the occurrence of frost when high-humidity air enters the outdoor heat exchanger for cooling, and can prevent or delay frost on the outdoor heat exchanger (the outdoor fan cannot blow the outdoor heat exchanger because it prevents the desiccant module from being blown to the outdoor heat exchanger, which has no effect of preventing frost); the indoor fan can blow the indoor heat exchanger through the arrangement of the indoor fan, so that the hot air after heat exchange through the indoor heat exchanger can blow the desiccant module to blow out the moisture, thereby improving the humidification effect on the room.

[0048] The preferred outdoor fan system of the present disclosure is a suction type structure, specifically, the airflow first passes through the heat exchanger and then passes through the fan under the action of the fan pressure difference. The outdoor unit suctions air because our solid dehumidification module needs to remove moisture from the air before the heat exchanger. The indoor side blowing type is the optimal structure of this solution, and the heated air can also be used to quickly dry the dehumidification module.

[0049] In some embodiments, when both the outdoor fan 51 and the indoor fan 52 are included, the air conditioner further includes a dual-shaft motor 6, one end of the dual-shaft motor 6 is connected to the first motor shaft, and the other end is connected to the second motor shaft, and the dual-shaft motor 6 is connected to the outdoor fan 51 through the first motor shaft to drive the outdoor fan 51 to operate, and is connected to the indoor fan 52 through the second motor shaft to drive the indoor fan 52 to operate. This is a preferred structural form of the air conditioner disclosed in the present invention, and the dual-shaft motor can simultaneously drive the outdoor fan to operate and the indoor fan to operate, so that one motor drives two fans to operate.

[0050] In some embodiments, an outdoor temperature and humidity sensor 61 and an indoor temperature and humidity sensor 62 are further included. The outdoor temperature and humidity sensor 61 can detect the temperature and humidity of the outdoor side to determine whether the outdoor heat exchanger has reached the conditions for defrosting and whether the defrosting has been completed. The indoor temperature and humidity sensor 62 can detect the temperature and humidity of the indoor side to determine whether the indoor air has reached the conditions for humidification and whether it has reached the conditions for heating. The present disclosure can also detect the temperature and humidity of the outdoor side through the outdoor temperature and humidity sensor to obtain whether the conditions for outdoor defrosting have been reached and whether the defrosting has been completed. The indoor temperature and humidity sensor can detect the temperature and humidity of the indoor side to determine whether the indoor air has reached the conditions for humidification and whether the humidification has been sufficient, and whether it needs to be heated or heated to meet the requirements.

[0051] In some embodiments, the position where the moisture absorption module 3 moves to the air inlet side of the outdoor heat exchanger 1 along the air flow is position A, and the position where the moisture absorption module 3 moves to the air outlet side of the indoor heat exchanger 2 along the air flow is position C;

[0052] The moisture absorption module 3 can also move to a position between the indoor heat exchanger 2 and the outdoor heat exchanger 1 when neither the outdoor heat exchanger 1 needs to be defrosted nor the indoor room needs to be humidified.

[0053] These are multiple preferred positions of the desiccant module disclosed in the present invention. The position of the air inlet side of the outdoor heat exchanger 1 along the air flow is position A, which enables the desiccant module to effectively dehumidify the outdoor area when it is at position A, thereby preventing or delaying frosting of the outdoor heat exchanger; the position of the air outlet side of the indoor heat exchanger 2 along the air flow is position C, which enables the desiccant module to effectively humidify the indoor area when it is at position C, thereby preventing the outdoor heat exchanger from being over-drying; when the desiccant module moves to the position between the indoor heat exchanger and the outdoor heat exchanger, it can neither absorb moisture from the outdoor area nor release moisture to the indoor area, which is suitable for situations where the outdoor humidity is not high and the indoor humidity is not too low.

[0054] Preferably, there are multiple moisture absorption modules, at least one module is set at each of the A, B, C and D positions, preferably four modules, and the modules are circulated between the indoor and outdoor sides through the guide rails to achieve moisture absorption and drying cycles, thereby achieving a continuous heating-humidification cycle mode. Figure 5 shown.

[0055] In heating mode, when the unit determines that it has entered the defrosting condition through the outdoor temperature sensing package, the solid cycle dehumidification module moves to position A through the guide rail, reducing the moisture in the air to avoid frost and achieve continuous indoor heating.

[0056] Preferably, in the heating mode, after the solid cycle dehumidification module of the unit completes moisture absorption in the outdoor unit, the module moves to the indoor heat exchanger side through the guide rail, along the airflow direction. After the hot air passes through the module containing moisture, the moisture evaporates to achieve indoor humidification.

[0057] Preferably, when the unit determines that it only needs to avoid frost and continuously heat without humidification, the desiccant module moves to position B, C or D as shown in the figure; when the desiccant module moves to position C, the desiccant module can be quickly dried.

[0058] In some embodiments, the position between the indoor heat exchanger 2 and the outdoor heat exchanger 1 includes a B position and a D position, wherein the B position is located on the way of the moisture absorption module 3 moving from the outdoor heat exchanger 1 toward the indoor heat exchanger 2, and the D position is located on the way of the moisture absorption module 3 moving from the indoor heat exchanger 2 toward the outdoor heat exchanger 1. These are two other preferred setting positions of the present disclosure, the moisture absorption module at the B position is in the process of moving after absorbing moisture from the outdoor heat exchanger, that is, the moisture absorption module is in a humid state at this time, and the moisture absorption module at the D position is in the process of moving back to the outdoor side after humidification from the indoor heat exchanger, that is, the moisture absorption module is in a dry state at this time.

[0059] In some embodiments, the air conditioner is a through-the-wall unit or a window unit, and / or the air conditioner further comprises a compressor 7. The air conditioner of the present disclosure is preferably a through-the-wall unit or a window unit, which is arranged at the position of the wall 8, and can effectively transfer the moisture between indoor and outdoor, transfer the outdoor moisture to the indoor to humidify the indoor, and prevent frost on the outdoor; the compressor can provide power to generate cooling.

[0060] The present disclosure also provides a control method for a continuous heating and humidifying air conditioner as described in any of the preceding items, wherein: when in a heating mode, and when the air conditioner includes an outdoor temperature and humidity sensor 61: the control method includes:

[0061] A detection step, detecting the outdoor temperature and humidity by means of the outdoor temperature and humidity sensor 61;

[0062] A judging step, judging whether the temperature outside the room is lower than a first preset temperature, and judging whether the humidity outside the room is higher than a first preset humidity;

[0063] Control step, when the temperature on the outdoor side is lower than the first preset temperature and the humidity on the outdoor side is greater than the first preset humidity, control the desiccant module 3 to move to the air inlet side of the outdoor heat exchanger 1 along the air flow to dehumidify the airflow before entering the outdoor heat exchanger 1.

[0064] The present invention can effectively judge when the outdoor heat exchanger is about to reach the defrosting condition by detecting the outdoor temperature and humidity, that is, it is easy to frost when the temperature is low and the humidity is high. At this time, the desiccant module is controlled to move to the air inlet side of the outdoor heat exchanger, and can dehumidify the airflow before entering the outdoor heat exchanger, thereby avoiding the frosting of the outdoor heat exchanger or prolonging its frosting time, ensuring effective and continuous heating in the room, and improving the indoor comfort.

[0065] In some embodiments, when the air conditioner includes an indoor temperature and humidity sensor 62:

[0066] The detection step further detects the indoor temperature and humidity through the indoor temperature and humidity sensor 62;

[0067] A determination step, determining whether the humidity inside the room is less than a second preset humidity;

[0068] Control step, when the humidity inside the room is less than the second preset humidity, control the moisture absorption module 3 to move to the air outlet side of the indoor heat exchanger 2 along the air flow, so as to humidify the air heated by the indoor heat exchanger 2 and then blow it into the room.

[0069] The present invention also detects the indoor humidity to effectively determine whether the indoor room needs humidification, and if humidification is needed, by controlling the desiccant module to move to the air outlet side of the indoor heat exchanger, the air heated by the indoor heat exchanger can be used to heat the water-rich desiccant module to blow the moisture into the room, thereby increasing the indoor humidity and completing effective humidification.

[0070] The above is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure. The above is only a preferred implementation of the present disclosure. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present disclosure, and these improvements and variations should also be regarded as the protection scope of the present disclosure.
