The present disclosure relates to air conditioning devices, and, more specifically, to an air conditioning device using an air conditioning system coupled with an evaporation cooling technique, through circulating the condensed water to process the waste heat.
The thermoelectric cooling chip based air conditioning device is a popular choice for a compact size air conditioning device as it is compact in size, makes no noises, does not use a refrigerant and is environmentally friendly, as compared to the traditional compression type air conditioning device.
However, the thermoelectric cooling chip operates by circulating the cooling effect provided on the surface to cool down the ambient temperature. When the temperature of the air flow is high during hot weather day plus particle pollution, it can likely adversely affect the efficiency of heat exchange, thereby reducing the cooling effect.
Besides, when one side of the thermoelectric cooling chip is performing the cooling operation, the other side of the thermoelectric cooling chip is performing the heating operation, and the generated waste heat is exhausted to the ambient and also indirectly raises the difficulty of cooling by the air conditioning device.
Therefore, there is a need to solve the prior art problems increasing the cooling efficiency and solving the problem of exhausted waste heat produced by the thermoelectric cooling chip.
In light of solving the foregoing problems of the prior art, the present disclosure provides an air conditioning device, comprising: a duct module and a heat exchange module. The duct module has opposing first and second regions, and comprises: a temperature control unit disposed at the second region of the duct module; a first air flow guide unit disposed at the first region, a second region or between the first region and the second region of the duct module; and a first liquid energy conducting element disposed at the first region of the duct module.
The heat exchange module is coupled to the duct module and configured for processing the waste heat produced by the temperature control unit, and has an accommodating case, a heat exchanger, a second liquid energy conducting element, a delivery duct, a driver unit and a second air flow guide unit. The accommodating case is used to collect the condensed water produced by the temperature control unit. The heat exchanger is used to remove the waste heat produced by the temperature control unit. The second liquid energy conducting element is used to remove the waste heat produced by the heat exchanger. The delivery duct is used to couple the second liquid energy conducting element, the accommodating case and the duct module in series. The driver unit is used to drive the condensed water to pass the delivery duct, such that the condensed water flows between the second liquid energy conducting element and the accommodating case. The second air flow guide unit is used to provide air flow to the heat exchanger. Therefore, the waste heat generated by the heat exchanger is allowed to be delivered to the second liquid energy conducting element to carry out the process of cooling by heat exchange.
In an embodiment, the heat exchanger is disposed between the second liquid energy conducting element and the second air flow guide unit.
In an embodiment, the first liquid energy conducting element comprises a water inlet, a water outlet and a water curtain module, the water curtain module is disposed in the inner side of the first region of the duct module, through the water inlet the condensed water is drawn to the water curtain module, and drawn out by the water outlet.

The control module 3 may comprise a setting unit 31 configured for setting up the threshold temperature for the duct module 1, and outputting the corresponding first control signal to each of the temperature control unit 13 or the first air flow guide unit 14, and the control module 3 controls the on/off action or the configuration of the temperature control unit 13 or the first air flow guide unit 14 by the first control signal.
The air conditioning device according to the present disclosure may further comprise a detecting module 4 configured for detecting the temperature of the air flow generated by the first air flow guide unit 14, at the time when it flows from the second region 12 of the duct module 1, and generating a corresponding temperature signal to the control module 3. Then the control module 3 in response outputs a corresponding second control signal to each of the temperature control unit 13 or the first air flow guide unit 14 based on the threshold temperature set up by the setting unit 31 and the temperature signal, such that the control module 3 further controls the on/off action or the configuration of the temperature control unit 13 or the first air flow guide unit 14 by the second control signal.
Firstly in step S1, the threshold temperature of the two duct modules 1A and 1B are set by the setting unit 31, wherein the threshold temperature is the target temperature for each duct module 1 desired to be reached in operation, and then the temperature control unit 13 and first air flow guide unit 14 of each duct module are started up. Steps S2 and S3 are then followed, wherein the control module 3 adjusts the first air flow guide units 14A and 14B of the duct modules 1A and 1B to be low loading (such as 30% loading, low rotational speed for the fan), or zero loading. At this time, the two duct modules are storing the cold, and a variable frequency motor technique can be applied in the control module 3 to not only capable of controlling the on/off the air flow generated by the first air flow guide unit 14, but also adjusting the magnitude of the air flow.
Subsequently, steps S4 to S7 are performed, for detecting the real time temperature of the duct modules 1A and 1B by the detecting module 4. When the real time temperature of the duct module 1A is lower than or equal to the cooling threshold temperature, the control module 3 changes the first air flow guide unit 14A to be high loading (such as 70% loading, higher rotational speed for the fan) or full loading, to allow the duct module 1A distribute the cold. The detecting module 4 would not carry out the first temperature detection for the duct module 1B, to allow the duct module 1B to continue to store cold, in order to separate the time of operation of the duct module 1A, and when the duct module 1B is higher than or equal to the cold distribution threshold temperature, the control module 3 then changes the first air flow guide unit 14B to low loading or zero loading.
Steps S8 to S11 are then performed to repeat steps S4 and S5, wherein the detecting module 4 detects the real time temperature of the duct modules 1A and 1B, and when the real time temperature of the duct module 1A is higher than or equal to the cold distribution threshold temperature, the control module 3 changes the first air flow guide unit 14A to be low loading or zero loading, to allow the duct module 1A to store cold, and on the other hand when the real time temperature of the duct module 1B is lower than or equal to the cooling threshold temperature, the control module 3 changes the first air flow guide unit 14B to be high loading or full loading, to allow the duct module 1B to distribute cold.
As such, through the aforementioned repeating cycles of alternate cooling, the output of the air conditioning device is able to be maintained in a stable low temperature, and energy is thus saved. Besides, the control module 3 can not only control the loading of the first air flow guide unit 14, but also adjust the loading of the temperature control unit 13, such that the cooling or heating efficiency is enhanced through such efficient distribution.
In an embodiment of the present disclosure, the air conditioning device may further comprise a power module 5 configured for providing the operational energy for the duct module 1, the heat exchange module 2, the control module 3 and the detecting module 4.
All embodiments of the air conditioning device according to the present disclosure with multiple ducts or single duct may further comprise an air collecting unit 6. The air collecting unit 6 has an air inlet 61 and an air outlet 62. The air inlet 61 faces towards the second region 12 of each duct module 1. The detecting module 4 can be disposed around the air outlet 62. In an embodiment, the air conditioning device according to the present disclosure utilizes the function of the air collecting unit 6 to collect the air flow generated from multiple duct modules 1, so as to increase the efficiency of cooling or heating.
In summary, the air conditioning device according to the present disclosure is based on the concept of a thermoelectric cooling chip, with the additional water curtain structure and waste heat treatment, which not only increase the efficiency of cooling, but also reduce the amount of waste heat exhausted outside, to reach a balance in temperature, which cannot be achieved by other air condition device on the market today.

The above embodiments can be modified by those with ordinary skill in the art without departing from the scope of the present disclosure as defined in the following appended claims.
