Description

Technical Field

[0001] The utility model relates to an indoor air conditioning device, in particular to a dual-channel variable-temperature dehumidification conditioning device. Background Art

[0002] At present, the commonly used dehumidification method is cold dehumidification, that is, cooling the air in the space that needs to be dehumidified. When the air temperature decreases, the relative humidity will increase until it reaches the dew point of the air. At this time, the water vapor in the air will condense from the air on the cold source such as hydrophilic aluminum foil, thereby achieving the purpose of dehumidification.

[0003] In traditional dehumidification solutions, there are two methods based on this principle: one is an external cold source, that is, the compressor is arranged separately in the machine room or outdoors, and there is only a cooling coil inside the dehumidifier host for dehumidification. Dehumidification using this method will cause the air temperature to drop significantly after dehumidification. In order to avoid problems such as decreased air supply comfort, it is generally necessary to reheat the cold air after dehumidification. The other method is an all-in-one machine with a built-in compressor. After dehumidification by the cold coil, the air will be reheated by the compressor and condenser. However, because the compressor generates a lot of heat during operation, the air supply temperature after dehumidification will increase significantly, generally reaching 3~7℃, which will also cause problems such as decreased air supply comfort.

[0004] Current conventional dehumidification equipment has a single usage scenario and lacks flexibility. It cannot take into account the dehumidification needs and air supply comfort requirements in damp and cold or humid and hot environments. In terms of functional design, this type of equipment focuses on supplying air to the room and providing fresh air, but tends to ignore the need for rapid exhaust, which has obvious limitations. Summary of the invention

[0005] The utility model aims to provide a dual-channel variable temperature dehumidification regulating device to improve the air supply comfort when the dehumidifier is used in different indoor and outdoor temperature environments, and to meet indoor air conditioning needs such as adding fresh air and quickly discharging sewage.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dual-channel variable temperature dehumidification adjustment device, which has two independent air cavities formed based on an outer shell and an air duct dividing plate, wherein a blower, a compressor, a second condenser and an evaporator are arranged in the first air cavity, and the first air cavity is provided with an air supply port toward the indoor room near the blower, and a return air port is arranged on the bottom side; an exhaust fan, a second electric switch valve and a first condenser are arranged in the second air cavity, and the second air cavity is provided with an exhaust port connected to the outdoors near the exhaust fan, and a fresh air port with a built-in third electric switch valve is arranged on the bottom side, and the two air cavities are provided with a first electric switch valve on the air duct dividing plate near the return air port and the fresh air port, which makes the two cavities controllable in on and off.

[0007] Furthermore, the outer shell is provided with a primary filter screen which crosses the two wind cavities near the first electric switch valve, and the first wind cavity is provided with a medium efficiency or higher efficiency filter screen in the downwind direction of the primary filter screen.

[0008] Furthermore, a microcontroller is integrated in the outer shell, each electric switch valve is connected to the microcontroller and switched under control, and the blower, exhaust fan and compressor are connected to the power supply through the microcontroller branch and are controlled to open and close, running more than two dehumidification working modes.

[0009] Compared with traditional dehumidification equipment with a single cold coil or a built-in compressor, the beneficial effects of the utility model are as follows: the dehumidification adjustment device overcomes the problems of traditional dehumidifiers with single functional design and few applicable scenarios. Through convenient valve, fan and compressor on and off control, it is suitable for dehumidification needs in variable temperature and humidity environments throughout the year. At the same time, it enables the dehumidifier to have functions such as fresh air supply and rapid exhaust under suitable weather conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The specific implementation modes of the present invention will be further described below in conjunction with the accompanying drawings of the embodiments, so that the technical solution of the present invention is easier to understand and grasp, thereby making a clearer definition of the protection scope of the present invention.

[0016] like Figure 1As shown, the dual-channel variable temperature dehumidification regulating device of the utility model has a box-type outer shell, and its internal structure is: the inner cavity of the outer shell is formed into an independent first air cavity 11 and a second air cavity 12 through an air duct partition plate. In summary: the first air cavity 11 is provided with a blower 2, a compressor 4, a second condenser 52 and an evaporator 6, and the first air cavity is provided with an air supply port toward the indoor A near the blower, and a return air port is provided on the bottom side; the second air cavity 12 is provided with an exhaust fan 3, a second electric switch valve 82 and a first condenser 51, and the second air cavity is provided with an exhaust port connected to the outdoor B near the exhaust fan, and a fresh air port with a built-in third electric switch valve 83 on the bottom side, and the two air cavities are provided with a first electric switch valve 81 on the air duct partition plate near the return air port and the fresh air port to control the on and off of the two cavities.

[0017] It can be seen that the two wind cavities are completely isolated when the first electric switch valve 81 is closed. In this way, the first wind cavity 11 is only connected to the indoor A, and the second wind cavity 12 is only connected to the outdoor B. When the first electric switch valve 81 is open, the two wind cavities are connected at the bottom. Looking at the second wind cavity alone, it is not a cavity structure that is completely connected from top to bottom. On the one hand, its fresh air outlet is controlled by the internally integrated third electric switch valve, so that it has the conditions to introduce fresh air into the second wind cavity; on the other hand, a second electric switch valve is also provided near the exhaust fan, so that the second wind cavity is further divided into cavities and the exhaust passage is blocked.

[0018] From the perspective of further detailed features, the outer shell 1 is provided with a primary filter 71 that crosses the two wind cavities near the first electric switch valve 81, and the first wind cavity 11 is provided with a medium-efficiency or higher-efficiency filter in the downwind direction of the primary filter. In the preferred embodiment shown in the figure, a high-efficiency filter 72 is selected. Here, the primary filter and the high-efficiency filter are classifications well known to those skilled in the art, so the detailed description of their types and product numbers is omitted. In addition, a microcontroller (not shown) is integrated in the outer shell, and each electric switch valve is connected to the microcontroller and switched under controlled status. The control instructions can be input to the microcontroller through the operation panel integrated on the surface of the outer shell or wireless remote control, and the above-mentioned air supply fan 2, exhaust fan 3, and compressor 4 are connected to the power supply through the microcontroller branch and are controlled to open and close, thereby realizing more than two dehumidification working modes of the device.

[0019] Specifically, the isothermal dehumidification mode is suitable in high temperature and high humidity weather, such as Figure 2As shown, the first electric switch valve 81 is controlled to be closed, and the supply fan 2, exhaust fan 3, second electric switch valve 82, and third electric switch valve 83 are all controlled to be opened. The indoor air flow circulates independently in the first air cavity for dehumidification and reheating to compensate for the temperature, and the outdoor air flow circulates independently in the second air cavity. In this process, most of the heat of the dehumidification operation is taken away by the exhaust air (the thermal conductivity of the air duct partition plate); after the indoor return air is condensed and dehumidified by the evaporator, the second condenser reheats the air to maintain the supply air at a comfortable temperature and humidity, achieving the goal of isothermal dehumidification.

[0020] In low temperature and high humidity weather conditions, the fresh air dehumidification mode is suitable, while in weather with suitable temperature and humidity, the positive pressure air supply mode is suitable. The airflow inside the device is the same in these two modes, the only difference is whether the compressor is turned on or off. Figure 3 As shown, in the fresh air dehumidification mode, the exhaust fan and the second electric switch valve are controlled to be closed, the supply fan, the compressor, the first electric switch valve and the third electric switch valve are all controlled to be opened, the airflow in the second air cavity is stagnant, the fresh air outlet and the return air outlet converge in the first air cavity, the indoor air flow circulates in the first air cavity in a one-way manner for dehumidification, and the mixed fresh air is moderately heated by the compressor. In the positive pressure air supply mode, the states of other fans and electric switch valves are maintained, and only the compressor is turned off. Because the fresh air reaches a suitable and comfortable temperature and humidity, there is no need to upgrade and reheat, and the airflow method is omitted.

[0021] The dehumidification and heating mode is suitable in low temperature and high humidity weather, such as Figure 4 As shown, the exhaust fan and three electric switch valves are controlled to be closed, while the supply fan and compressor are controlled to be opened. In this way, the airflow in the second air cavity is stagnant, which is equivalent to an idle state, while the indoor airflow circulates in the first air cavity in a one-way manner for dehumidification, and the second condenser reheats the air to maintain the supply air at a comfortable temperature and humidity.

[0022] When someone is smoking or the room is unoccupied for a long time and needs to be reoccupied, the quick exhaust mode is suitable. Figure 5 As shown, the air supply fan, the compressor and the third electric switch valve are controlled to be closed, and the exhaust fan, the first electric switch valve and the second electric switch valve are controlled to be opened. As a result, the airflow in the first air cavity is stagnant, which is equivalent to an idle state; and the indoor airflow is discharged from the return air outlet and the second air cavity, which is conducive to quickly discharging the indoor dirty air to the outside.

[0023] From the above introduction to the scheme and detailed description of the embodiments of the dual-channel variable temperature dehumidification adjustment device of the utility model, it can be seen that compared with the traditional dehumidification equipment with a single cold coil or a built-in compressor, this scheme has substantial characteristics and progress, and its technical effect is reflected in: the dehumidification adjustment device overcomes the problem that the traditional dehumidifier has a single functional design and few applicable scenarios. Through the convenient start and stop control of valves, fans and compressors, it is suitable for the dehumidification needs in variable temperature and humidity environments throughout the year. At the same time, the dehumidifier can have functions such as fresh air supply and rapid exhaust under suitable weather conditions.

[0024] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the scope of protection required by the present invention.
