Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning and refrigeration, in particular to an air conditioning and refrigeration optimization control device. Background Art

[0002] Air conditioners are household appliances commonly used in our daily lives. They can adjust parameters such as the temperature, humidity, cleanliness and air flow rate of the air in a room (or enclosed space or area) to meet the requirements of human comfort or process. The air conditioning refrigeration principle refers to the principle of air conditioning refrigeration operation. After the air conditioner is powered on, the low-pressure steam of the refrigerant in the refrigeration system is sucked in by the compressor and compressed into high-pressure steam and then discharged to the condenser. The indoor air circulates continuously to achieve the purpose of lowering the temperature.

[0003] Most of the existing air conditioners are variable frequency air conditioners, which can automatically adjust the operating power according to the indoor temperature to keep the indoor temperature stable. However, if the user does not turn off the air conditioner when going out, the air conditioner will keep running, which will waste a lot of unnecessary electricity. In addition, most of the existing air conditioners only adjust the indoor temperature. In comparison, it is easy to ignore the indoor air humidity. Since the indoor temperature is prone to humidity in rainy weather, the indoor air humidity also needs to be adjusted. Moreover, the timing settings of existing air conditioners are mostly only accurate to 0.5 hours, which is inconvenient for users. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the utility model provides an air-conditioning refrigeration optimization control device.

[0005] The technical solution of the utility model is achieved in this way:

[0006] An air conditioning refrigeration optimization control device comprises an air conditioning body and a control mechanism, wherein the air conditioning body comprises an outer shell and a panel, wherein the panel is arranged below the outer shell and is detachably connected to the outer shell, wind shields are respectively arranged on the four sides of the panel, an infrared sensor, a temperature sensor, a humidity sensor and a first display screen are arranged on the panel, the air conditioning body is electrically connected to the control mechanism, the control mechanism comprises a controller, a second display screen, a voice area and control buttons, and an inverter, a compressor, an electronic expansion valve and a fan are arranged in the air conditioning body.

[0007] Preferably, the infrared sensor, the temperature sensor, the humidity sensor and the first display screen are respectively arranged at the four corners of the panel.

[0008] Preferably, the controller is arranged inside the control mechanism, the second display screen is arranged above the outside of the control mechanism, the voice area is arranged below the second display screen, and the control button is arranged below the voice area.

[0009] Preferably, the infrared sensor, the temperature sensor and the humidity sensor are all electrically connected to the controller.

[0010] Preferably, the frequency converter, the compressor, the electronic expansion valve and the fan are all electrically connected to the controller.

[0011] Preferably, the control mechanism is detachably connected to the indoor wall.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides an air-conditioning refrigeration optimization control device. The device is provided with a control mechanism, an infrared sensor, a temperature sensor, and a humidity sensor. When the infrared sensor senses that there is no human activity in the room, the controller controls the frequency converter to adjust the rotation speed of the compressor, so that the indoor temperature is quickly stabilized near the set value. If no human activity is sensed in the room for two consecutive hours, the air-conditioning is controlled to be turned off. When the humidity sensor senses that the indoor humidity is high, the controller controls the opening of the electronic expansion valve to increase, thereby increasing the flow rate of the refrigerant. After more refrigerant enters the evaporator, it will absorb more heat, so that the surface temperature of the evaporator in the air conditioner is reduced. When the water vapor in the air encounters the low-temperature evaporator, it will be more likely to condense into water droplets, thereby reducing the humidity in the air. At the same time, the air conditioner is timed by the control button on the control mechanism, and the time can be accurate to minutes. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-2The utility model is an air conditioning refrigeration optimization control device, comprising an air conditioning body 1 and a control mechanism 2, the air conditioning body 1 and the control mechanism 2 are electrically connected, the control mechanism 2 comprises a controller, a second display screen 201, a voice area 202 and a control button 203, the controller is arranged inside the control mechanism 2, the second display screen 201 is arranged above the outside of the control mechanism 2, the voice area 202 is arranged below the second display screen 201, the control button 203 is arranged below the voice area 202, and the second display screen 201, the voice area 202 and the control button 203 are all electrically connected to the controller. The air conditioning body 1 comprises a shell 3 and a panel 4, the panel 4 is arranged below the shell 3 and is detachably connected to the shell 3, the four sides of the panel 4 are respectively provided with windshields 5, the windshields 5 can control the direction of the air conditioning wind blowing outward by controlling the rotation angle of the control mechanism 2; the four corners of the panel 4 are respectively provided with infrared sensors 6, temperature sensors 7, humidity sensors 8 and a first display screen 9, the first display screen 9 is used to display the temperature set by the air conditioner. The infrared sensor 6, the temperature sensor 7 and the humidity sensor 8 are all electrically connected to the controller; the air conditioner body 1 and the control mechanism 2 are electrically connected, the control mechanism 2 includes a controller, a second display screen 201, a voice area 202 and a control button 203, and the air conditioner body 1 is provided with a frequency converter, a compressor, an electronic expansion valve and a fan, and the frequency converter, the compressor, the electronic expansion valve and the fan are all electrically connected to the controller.

[0019] Furthermore, the second display screen 201 can display the real-time temperature and real-time humidity of the room. When the control button 203 is used to perform a timed operation on the air conditioner, the input time will be displayed on the second display screen 201. The control button 203 can also be used to preset the indoor air humidity.

[0020] Furthermore, when the infrared sensor 6 senses that there is no human activity in the room, the controller controls the inverter to adjust the speed of the compressor so that the indoor temperature quickly stabilizes near the set value. If no human activity is sensed in the room for two consecutive hours, the air conditioner is controlled to turn off, which solves the problem of existing air conditioners that if the user goes out and does not turn off the air conditioner, the air conditioner will keep running, wasting a lot of unnecessary electricity.

[0021] Furthermore, when the humidity sensor 8 senses that the indoor humidity is low, the controller controls the opening of the electronic expansion valve to increase, increasing the flow rate of the refrigerant to increase the indoor humidity. When the humidity sensor 8 senses that the indoor humidity is high, the controller controls the opening of the electronic expansion valve to increase, increasing the flow rate of the refrigerant. After more refrigerant enters the evaporator, it will absorb more heat, thereby lowering the surface temperature of the evaporator in the air conditioner. When the water vapor in the air encounters the low-temperature evaporator, it will more easily condense into water droplets, thereby reducing the humidity in the air. This solves the problem that most existing air conditioners only adjust the indoor temperature and the indoor temperature is easily humid in rainy weather.

[0022] Furthermore, the control button 203 can be used to time the air conditioner, and the timing time can be accurate to the minute, which solves the problem that the timing settings of existing air conditioners are mostly only accurate to 0.5 hours, which is inconvenient for users.

[0023] The working principle of an air conditioning refrigeration optimization control device provided by the utility model is:

[0024] When in use, turn on the air conditioner and use the control button 203 to adjust the air conditioner temperature. When the infrared sensor 6 senses that there is no activity in the room, the controller controls the inverter to adjust the speed of the compressor so that the indoor temperature quickly stabilizes near the set value. If no activity is sensed in the room for two consecutive hours, the voice area 202 on the control mechanism 2 will issue a voice reminder that the air conditioner is about to be turned off. If no one responds, the air conditioner is controlled to be turned off. If someone responds, the air conditioner continues to run; when the humidity sensor 8 senses that the indoor humidity is high, the controller controls the opening of the electronic expansion valve to increase, increase the flow of the refrigerant, and more refrigerant will absorb more heat after entering the evaporator, so that the surface temperature of the evaporator in the air conditioner is reduced. When the water vapor in the air encounters the low-temperature evaporator, it will more easily condense into water droplets, thereby reducing the humidity in the air. The desired air humidity can also be pre-set through the control button 203; when timing is required, use the control button 203 to enter the timing time.

[0025] The utility model provides an air-conditioning refrigeration optimization control device. The device is provided with a control mechanism 2, an infrared sensor 6, a temperature sensor 7, and a humidity sensor 8. When the infrared sensor 6 senses that there is no human activity in the room, the controller controls the frequency converter to adjust the rotation speed of the compressor, so that the indoor temperature is quickly stabilized near the set value. If no human activity is sensed in the room for two consecutive hours, the air conditioner is controlled to be turned off. When the humidity sensor 8 senses that the indoor humidity is high, the controller controls the opening of the electronic expansion valve to increase, thereby increasing the flow rate of the refrigerant. After more refrigerant enters the evaporator, it will absorb more heat, so that the surface temperature of the evaporator in the air conditioner is reduced. When the water vapor in the air encounters the low-temperature evaporator, it will be more likely to condense into water droplets, thereby reducing the humidity in the air. At the same time, the air conditioner is timed by the control button 203 on the control mechanism 2, and the time can be accurate to minutes.
