Problems solved by technology

[0003] In the existing automatic air-conditioning control system for automobiles, in the heating mode, the compressor is always on, and the blower works at the corresponding power. When the humidity is greater than or equal to the calibrated humidity, the front windshield will be fogged, which will affect the driver's driving vision. If the driver manually turns on the defogging mode after the front windshield is fogged, it will affect driving safety, so Car air conditioning systems run the compressor all the time to prevent fogging, but this is a huge waste of energy

Embodiment 1

[0033] This embodiment provides a vehicle-mounted energy-saving automatic air-conditioning control method, such as figure 1 shown, including:

[0034] 100. Determine whether the air conditioning system is in heating mode,

[0035] 200. If the air-conditioning system is in the heating mode, the air-conditioning system turns off the compressor, switches to internal circulation, compares the real-time temperature Tn in the car with the temperature Ts set by passengers, and compares the real-time temperature Tn in the car with the temperature Ts set by passengers. The difference ΔT=|Ts−Tn| of the set temperature Ts is used to obtain the gear position B of the air volume before step 300 is performed. The relationship between the gear variable ΔB and ΔT of the gear B of the air volume is: ΔB=(3°C-ΔT) / 3°C.

[0036] For example, when ΔT=3°C, ΔB=0, that is, keep the air volume gear unchanged; when ΔT=6°C, ΔB=-1, that is, the air volume gear needs to be lowered by one gear, (i.e. the...

Embodiment 2

[0046] This embodiment provides a vehicle-mounted energy-saving automatic air-conditioning control device, such as figure 2 As shown, it includes: a judgment unit 20 connected to the control unit 10, a first temperature comparison unit 30, a humidity comparison unit 40, and an air conditioning system 50, and the air conditioning system 50 is also connected to the judgment unit 20.

[0047] The judging unit 20 is used to judge whether the air-conditioning system 50 is in the heating mode, but not limited to, if the air-conditioning system 50 is in the heating mode, the initial preset is to turn off the compressor and switch to internal circulation.

[0048]When the air conditioning system 50 is in the heating mode, the first temperature comparison unit 30 is used to compare the difference ΔTc=Tn-Tw between the real-time outside temperature Tw and the real-time inside temperature Tn with the calibrated inside and outside temperature difference ΔTy, The humidity comparison unit ...

Abstract

The invention relates to the field of air-conditioning equipment, and discloses a vehicle-mounted energy-saving automatic air-conditioning control method. Compare the difference between the real-time temperature Tw outside the vehicle and the real-time temperature Tn inside the vehicle ΔTc=Tn‑Tw with the calibrated temperature difference ΔTy inside and outside the vehicle, and compare the real-time humidity Hn inside the vehicle with the calibrated inside humidity Hy. If the temperature difference between inside and outside the vehicle ΔTc ≥ΔTy, and the humidity in the car Hn≥Hy, then turn on the compressor, the compressor will run at the preset output power, turn on the air volume to the preset gear, and start the external circulation, if ΔTc<ΔTy, or Hn<Hy, Then execute steps 1 to 2 in a loop. The technical solution can save energy while ensuring that the front windshield does not fog up, thereby improving driving safety.

technical field [0001] The invention relates to the field of air-conditioning equipment, in particular to a vehicle-mounted energy-saving automatic air-conditioning control method and device. Background technique [0002] In the automatic air conditioning control system of the car, the compressor will always operate in the heating mode to ensure that the front windshield will not be fogged. [0003] In the existing automatic air-conditioning control system for automobiles, in the heating mode, the compressor is always on, and the blower works at the corresponding power. When the humidity is greater than or equal to the calibrated humidity, the front windshield will be fogged, which will affect the driver's driving vision. If the driver manually turns on the defogging mode after the front windshield is fogged, it will affect driving safety, so Car air conditioning systems run the compressor all the time to prevent fogging, but this is a huge waste of energy.
