Please refer to FIG. 1 , the embodiment of the present application discloses a first air conditioning system 10 . The air conditioning system 10 includes a cooling and heating device 1 , a pipeline 2 , a water pump 3 and heat exchange plates 4 distributed at intervals. There is a heat exchange medium in the pipeline 2 (in the embodiment shown in FIG. 1 , the heat exchange medium is antifreeze, and further, the antifreeze is water). The heating and cooling device 1 , the pipeline 2 , the water pump 3 and the heat exchange plate 4 form a circuit for the heat exchange medium to flow, and there is no limit to how the circuit is formed. The heat exchange medium is not limited, and in the embodiment of the present application, it has two states of hot and cold, so as to be able to exchange heat with the heat exchange plate 4 . The heat exchange plate 4 conducts heat conduction with the air around the heat exchange plate 4 to heat up or cool down the space around the heat exchange plate 4 . The structure is not limited, as long as it can achieve the aforementioned purpose.

Based on the structure of the above-mentioned air-conditioning system 10, its mode of operation is as follows:

In the heating mode, the cooling and heating device 1 heats the heat exchange medium (such as antifreeze, which can be water), and under the delivery of the water pump 3, the heated heat exchange medium (such as antifreeze Liquid, antifreeze can be water) circulates in the pipe 2, and exchanges heat with the heat exchange plate 4.

As set up above, since the air-conditioning system 10 exchanges heat with the heat exchange plate 4 through a heat exchange medium (such as antifreeze, which can be water), the heat exchange plate 4 conducts heat with air, so that the heat exchange plate 4 4 The surrounding space heats up or cools down, thus, the air conditioning system 10 has at least the following advantages:

1) Due to the heat conduction between the heat exchange plate 4 and the air to heat up or cool down the space around the heat exchange plate 4, the air blower is not used to make the air flow to generate cold or hot air (it can be called a windless air conditioner), therefore, there will be no There is a situation where the wind blows towards the consumer (if the air conditioning system 10 is applied to a vehicle, the consumer is the driver and/or passenger), which improves the comfort; Noise is generated when the blower is running. On the other hand, it will not generate noise due to the flow of cold or hot air. The noise is low and the comfort is improved;

Therefore, the air flow is not used by the blower and there is no need to consider the air volume and energy saving by regional control The problem is that the control is convenient, and the spacing of the heat exchange plates 4 also leads to uniform cooling and heating in the space where the air conditioning system 10 is applied. , where the temperature in some regions is low.

3) Due to heat conduction between the heat exchange plate 4 and the air to heat up or cool down the space around the heat exchange plate 4, components such as dampers, cores, and air ducts in traditional air conditioning systems are eliminated, not only freeing up a lot of space, but also, It also saves costs because these components are not needed, and the air-conditioning system 10 has a simple structure and is easy to maintain.

Please refer to FIG. 3 and in conjunction with FIG. 4 and FIG. 5 , the embodiment of the present application provides a second air conditioning system 10.

The fourth solenoid valve 74 is connected to the second solenoid valve 72 , the first solenoid valve 71 and the compressor 7 . The fifth solenoid valve 75 is connected to the compressor 7 and the third solenoid valve 73 as well as to the heat exchanger 6 and the second solenoid valve 72 .

Please refer to FIG. 4 in combination with FIG. 3 , in the heating mode, the first solenoid valve 71 , the second solenoid valve 72 and the third solenoid valve 73 are closed, and the electromagnetic thermal expansion valve 81 is opened, thus, the circuit is: Heater 6—electromagnetic thermal expansion valve 81—heat exchange plate 4—full-diameter electronic expansion valve 9 (under heating mode, each full-diameter electronic expansion valve 9 realizes the passage function)—fourth solenoid valve 74—compressor 7—the first Five solenoid valves 75—heat exchanger 6. The refrigerant flows in the above circuit to realize the heating function.

The refrigerant flows in the above circuit to realize the cooling function. In the cooling mode, the heat exchange plate 4 conducts heat with the air to cool down the space around the heat exchange plate 4 .

As set up above, the second type of air conditioning system 10 also has the aforementioned improvement of comfort because it uses the heat exchange plate 4 and air heat transfer to heat up or cool down the space around the heat exchange plate 4; The air volume is controlled in different areas to save energy, and the control is convenient; the air door, core body, air duct and other components in the traditional air conditioning system are cancelled, which not only releases a lot of space, but also the heat exchange medium used in the first air conditioning system It is antifreeze, and the heat exchange medium of the second air conditioning system is refrigerant, and the difference in heat exchange medium causes the structure of the air conditioning system to change. For example, comparing Figure 1 and Figure 3, it can be seen that the first air conditioning system uses Compared with the heat exchange of heat exchange plate 4 and the second type of air conditioning system using refrigerant and heat exchange plate 4, the pressure required to transmit the heat exchange medium is smaller, and the structural requirements for the application object are lower. Take the vehicle as an example to describe this advantage in detail; as another example, the structure of the first type of air-conditioning system is simpler than that of the second type of air-conditioning system, and the cost is also lower, and the number of control valves 13 in the first type of air-conditioning system is less than that of the second type The number of full-diameter electronic expansion valves 9 in the air-conditioning system is low in cost and simple in structure, the cost of the water pump is lower than that of the compressor, and the electromagnetic thermal expansion valve is not required, so the cost is low and the structure is simple.

Comparing Fig. 3 and Fig. 1, in the first air-conditioning system, the water pump 3 is used to transport the heat exchange medium (antifreeze), and the cooling and heating device 1 is used to heat or cool down the heat exchange medium, finally making the heat exchange medium (antifreeze) Liquid) flows in the pipeline 2, the water pump 3 and the cooling and heating device 1 cooperate with the opening or closing of the relevant control valve to realize the heat exchange between the heat exchange medium and the heat exchange plate 4, and the heat exchange plate 4 conducts heat with the air to realize heating or cooling. In the second air conditioning system, one function of the compressor 7 is to transport the heat exchange medium (refrigerant), and the heat exchanger 6 is used to heat or cool down the heat exchange medium.
