[0025] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0026] Example:

[0027] See also Figure 1This embodiment discloses an air-conditioning fixed-point temperature control device, comprising:

[0028] Housing 1, said housing 1 being arranged on the air outlet of air conditioner A;

[0029] a first air flow channel 2, the first air flow channel 2 being connected to the housing 1 to form a circulating air flow loop;

[0030] The second air flow channel 3 includes a plurality of branches, the air inlets of the branches are connected to the first air flow channel, and the air outlets of the branches are arranged on the temperature rise and fall points 4.

[0031] It should be noted that, in this embodiment, the heating and cooling points 4 can be workstations in an office, thereby improving the utilization rate of the heating or cooling air of the air conditioner A and effectively reducing the energy consumption of the air conditioner A.

[0032] In a specific embodiment, the first airflow channel 2 is connected to the indoor wall by a clamp or bolt, or the first airflow channel 2 in this embodiment can be set on the indoor ceiling. In addition, the first airflow channel 2 in this embodiment can be fixed in various ways.

[0033] In a more specific embodiment, the second air flow channel 3 can be formed by splicing a plurality of pipes, and the pipes are fixed to the wall through U-shaped clamps, so that the branch air outlet of the second air flow channel 3 is set at the workstation in the office.

[0034] In a specific embodiment, the device further comprises:

[0035] An electrically controlled isolation device, provided on the air inlet or outlet of the branch, for isolating the airflow between the branch and the first airflow channel 2 or the airflow between the branch and the heating and cooling point 4;

[0036] A blower fan is provided at the air outlet of the branch line;

[0037] Temperature sensors are installed on air conditioner A and heating and cooling point 4;

[0038] The air pressure sensor is provided in the first air flow channel 2 and is used to monitor the air pressure in the first air flow channel 2. If the air pressure is too high, the air conditioner A needs to be turned off or the speed of the fan of the air conditioner A needs to be reduced;

[0039] A controller is electrically connected to the air conditioner A, the electrically controlled partition device, the air blower, the temperature sensor and the air pressure sensor, and is used to control the electrically controlled partition device, the air blower and the air conditioner A according to data from the temperature sensor and the air pressure sensor.

[0040] In this embodiment, the temperature sensor may be an infrared sensor, which is used to collect the temperature at the air conditioner A and the temperature at the heating and cooling point 4, and compare the two temperatures to determine whether the electric partition device needs to be opened.

[0041] In a more specific embodiment, the electrically controlled isolation device includes a signal receiver, a stepper motor, and a drive structure connected in sequence. The signal receiver is used to receive a signal wirelessly transmitted from a controller and, based on the signal, control the stepper motor to start or stop. The stepper motor drives the drive structure to isolate the airflow between the branch and the first airflow channel 2 or the airflow between the branch and the heating and cooling point 4. It should be noted that reversing the stepper motor can open the airflow between the branch and the first airflow channel 2 or the airflow between the branch and the heating and cooling point 4.

[0042] In one specific embodiment, the housing 1 is bolted to the air conditioner A. The internal cavity of the housing 1 communicates with the air outlet of the air conditioner A, and a sealing strip is provided on the edge of the housing 1. Furthermore, the first airflow channel 2 is internally connected to the housing 1 via a perforated connection, and a sealing strip is provided at the connection point. Additionally, the air inlet of the branch circuit is internally connected to the first airflow channel 2 via a perforated connection, and a sealing strip is provided at the connection point.

[0043] In a specific embodiment, the first air flow channel 2 and the second air flow channel 3 are made of polypropylene air ducts, which have good thermal insulation performance, excellent chemical resistance and low price.

[0044] This embodiment discloses an air conditioner fixed-point temperature adjustment device, and the working process is as follows:

[0045] Mode 1: When there is someone at the workstation, if the temperature at the workstation is too high, the two electrically controlled partition devices and the blower of the branch will be opened, and cold air will be output. The temperature sensor at air conditioner A will detect whether the temperature is suitable to ensure the output of cold air. When the temperature sensor at the workstation detects that the temperature is suitable, the two electrically controlled partition devices and the blower of the branch will be closed. At this time, the air pressure sensor monitors the air pressure in the first air flow channel 2. If the air pressure is greater than the air pressure threshold value, the air conditioner A will be controlled to reduce the fan speed, thereby reducing the output of cold air to achieve air pressure stability.

[0046] Mode 2: When there is someone at the workstation, if the temperature at the workstation is too low, the two electrically controlled partition devices and the blower of the branch will be opened, and hot air will be output. The temperature sensor at air conditioner A will detect whether the temperature is suitable to ensure the output of hot air. When the temperature sensor at the workstation detects that the temperature is suitable, the two electrically controlled partition devices and the blower of the branch will be closed. At this time, the air pressure sensor monitors the air pressure in the first air flow channel 2. If the air pressure is greater than the air pressure threshold value, the air conditioner A will be controlled to reduce the fan speed, thereby reducing the output of hot air to achieve air pressure stability.

[0047] Since there are slight differences in temperature between the working position and the immediate surrounding environment when there is no one, in this embodiment, a first infrared sensor can also be set at the working position, and a second infrared sensor can be set in the immediate vicinity (beyond 2m and within 3m) of the working position, so as to achieve precise control.

[0048] In Mode 1: Let the temperature at the working position be T1 °C (close to 36 °C), and the temperature of the immediate surrounding environment of the working position be T2 °C. Let the upper critical value be A °C, the lower critical value be B °C, and the threshold 1 be C °C. Then when B < T1 - T2 < A, the two electrically controlled partition devices of the branch are closed; when T1 - T2 < C, the electrically controlled partition device is opened. For example, A is 2, B is -2, and C is 10. The settings can be changed according to the actual situation.

[0049] In Mode 2: Let the temperature at the working position be Tα °C (close to 36 °C), and the temperature of the immediate surrounding environment of the working position be T2 °C. Let the upper critical value be A °C, the lower critical value be B °C, and the threshold 1 be C °C. Then when B < T1 - T2 < A, the two electrically controlled partition devices of the branch are closed; when T1 - T2 > C, the electrically controlled partition device is opened. For example, A is 2, B is -2, and C is 15. The settings can be changed according to the actual situation.

[0050] Due to differences in factors such as regions, the infrared sensor temperature thresholds set for air conditioner A are also different. In Mode 1, the air conditioner temperature threshold should be about 26 °C, which should be close to (T1 - C) °C; in Mode 2, the air conditioner temperature threshold should be about 21 °C, which should be close to (T1 - C) °C.

[0051] According to the ideal gas state equation, PV = nRT. When V and T are constant, the air pressure and the amount of substance n are in a proportional relationship. Also, since the pressure difference between the inside and outside of the device is positively correlated with the pipe mouth wind speed, the control of the pipe mouth wind speed can be achieved by setting different air pressure preset values and the rotation speed of the air blower.

[0052] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
