[0035] As Figure 1 shown, an air-conditioning air supply temperature and humidity adjustment device includes a heater 10 for heating the air supply of the air conditioner, a humidifier 11 for humidifying the air supply of the air conditioner; it further includes a heating electric valve for adjusting the flow rate of steam entering the heater, a humidifying electric valve for adjusting the flow rate of water entering the humidifier, a temperature sensor 8 for detecting the temperature of the air supply of the air conditioner, a humidity sensor 9 for detecting the humidity of the air supply of the air conditioner, a PLC 51 for issuing an opening instruction based on a preset electric valve opening value and receiving the actual electric valve opening value; the heating electric valve is communicated with the heater through a water pipe; the heater is communicated with the humidifying electric valve through a water tank 13 and a water pump 14, and the humidifying electric valve is communicated with the humidifier; the heating electric valve includes a heating electric valve body 1 and a heating electric valve head 3; the humidifying electric valve includes a humidifying electric valve body 2 and a humidifying electric valve head 4; the heating electric valve head is connected above the heating electric valve body, and the humidifying electric valve head is connected above the humidifying electric valve body; the heating electric valve head is electrically connected to the PLC, and the humidifying electric valve head is electrically connected to the PLC; a heating electric valve head red light 31 for indicating that the actual opening of the heating electric valve does not match the set opening, and a heating electric valve head green light 32 for indicating that the actual opening of the heating electric valve matches the set opening are provided on the heating electric valve head; a humidifying electric valve head red light 41 for indicating that the actual opening of the humidifying electric valve does not match the set opening, and a humidifying electric valve head green light 42 for indicating that the actual opening of the humidifying electric valve matches the set opening are provided on the humidifying electric valve head; the temperature sensor is also electrically connected to the PLC for judging whether the actual opening of the electric valve matches the preset opening.

[0036] A heater and a humidifier are disposed within the air conditioner 6, and the humidity sensor is electrically connected to the PLC; the air conditioner 6 further includes a blower 12 for sending the air conditioner air adjusted in temperature and humidity into the workshop 7.

[0037] In some embodiments, a heating electric valve head fan 33 is provided at the top of the heating electric valve head.

[0038] In some embodiments, a humidifying electric valve head fan 43 is provided at the top of the humidifying electric valve head.

[0039] In some embodiments, a heating electric valve head vent hole 34 is provided at the bottom of the heating electric valve head.

[0040] In some embodiments, a humidifying electric valve head vent hole 44 is provided at the bottom of the humidifying electric valve head.

[0041] In some embodiments, a display screen 52 is further included, and the display screen is electrically connected to the PLC; the display screen includes a heating electric valve opening set value operation unit 521, a heating electric valve opening actual value display unit 522, a humidifying electric valve opening set value operation unit 523, and a humidifying electric valve opening actual value display unit 524.

[0042] The display screen and the PLC form a part of the control cabinet 5.

[0043] Steam passes through the heating electric valve and enters the heater within the air conditioner. The steam heats the air sent into the air conditioner through the heater, thereby adjusting the temperature of the air supply.

[0044] After the steam is cooled in the heater, it flows out of the heater and enters the water tank. Tap water is only replenished when the water in the water tank is insufficient, thereby realizing the secondary utilization of water resources and saving water.

[0045] When the air conditioner needs to humidify the air supply, the water in the water tank enters the humidifier within the air conditioner through a water pump and a humidifying electric valve. The water is sprayed out of the humidifier to humidify the air sent into the air conditioner. Under the action of the blower, the air sent into the air conditioner is transported to the workshop through the air duct, thereby adjusting the temperature and humidity of the workshop.

[0046] A temperature sensor is installed inside the air conditioner. The temperature sensor can detect the supply air temperature and transmit the temperature detection value to the PLC. When heating of the supply air is required, the opening value can be set through the heating electric valve opening value setting unit. After setting the opening parameter, the heating electric valve opens to the corresponding position. After the heating electric valve is fully opened, it will return its actual opening value. The PLC compares the set value with the actual value. If they do not match, it will be indicated by the red light on the heating electric valve head. The specific form of the red light flashing in this disclosure is not specifically limited, such as flashing every 0.5 seconds. The staff can then know that the electric valve has a fault and immediately repair the fault to ensure that the temperature and humidity of the air supply in the workshop are in a normal state.

[0047] If the PLC determines that the actual value is the same as the set value, it will be indicated by the green light on the heating electric valve head, and the staff can know that the electric valve is in a normal working state now.

[0048] To further safeguard the heating electric valve, a heating electric valve head fan is also provided at the top of the heating electric valve head of the heating electric valve. When the temperature of the electric valve head is relatively high, low-temperature fresh air enters through the ventilation holes of the heating electric valve head, thereby cooling the heating electric valve.

[0049] The humidity sensor detects the humidity of the air supply of the air conditioner and transmits the detection value to the PLC. When humidification is required, the opening value is set through the humidifying electric valve opening value setting unit. The humidifying electric valve opens to a certain position based on the set opening. After the humidifying electric valve is fully opened, it returns the actual value to the PLC. Through comparison, if they do not match, it indicates that the electric valve has a fault through the red light on the humidifying electric valve head. If they match, it is indicated by the green light on the humidifying electric valve head.

[0050] A humidifying electric valve head fan is installed at the top of the humidifying electric valve head of the humidifying electric valve to cool the humidifying electric valve head. When the temperature of the humidifying electric valve head is relatively high, the humidifying electric valve head fan starts to operate, takes away the heat of the humidifying electric valve head, and supplements low-temperature fresh air through the ventilation holes of the humidifying electric valve head.

[0051] Please note that for the relevant descriptions of the fault monitoring of the humidifying electric valve that are not described in detail, please refer to the relevant content of the fault monitoring of the above heating electric valve.

[0052] This disclosure can almost ensure that the supply air temperature and humidity in the workshop are always in a normal state.

[0053] Although some specific embodiments of the present disclosure have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present disclosure. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present disclosure. The scope of the present disclosure is defined by the appended claims.
