Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes an air conditioner refrigeration control method, device and air conditioner according to the present invention with reference to fig. 1 to 3.
As shown in fig. 1, the present embodiment provides an air-conditioning refrigeration control method, and an execution main body of the method may be an air-conditioning controller or a server. The method comprises the following steps:
and step 111, acquiring the body surface temperature of the human body and the air outlet temperature of the air conditioner.
Wherein, wearable electronic equipment such as this embodiment can adopt intelligent wrist-watch, intelligent bracelet to gather human body surface temperature to the air outlet temperature of air conditioner is gathered to the temperature sensor of the air outlet of air conditioner is located to the accessible.
And 112, controlling the opening degree of an electronic expansion valve of the air conditioner according to the threshold range of the temperature difference value between the body surface temperature and the outlet air temperature, so that the temperature difference value reaches the preset temperature.
And 113, controlling the rotating speed of a fan of the air conditioner according to the threshold range of the body surface temperature. The opening degree of the electronic expansion valve comprises a plurality of opening degree values, the rotating speed of the fan comprises a plurality of rotating speed values, and the plurality of opening degree values and the plurality of rotating speed values are respectively matched in a one-to-one correspondence mode according to the sequence from large to small. That is, in the present embodiment, when the electronic expansion valve is controlled to maintain a relatively large opening value, the fan is controlled to operate at a relatively large rotation speed value, and when the electronic expansion valve is controlled to maintain a relatively small opening value, the fan is controlled to operate at a relatively small rotation speed value.
Specifically, when the method shown in this embodiment is used for refrigerating and controlling the temperature of the indoor environment, when the temperature difference between the body surface temperature and the outlet air temperature is large, the opening of the electronic expansion valve can be controlled to be increased, so as to ensure that the fan operates at a large rotation speed; along with the refrigeration operation of air conditioner, when the difference in temperature value of body surface temperature and air-out temperature is less, also can control the aperture that reduces electronic expansion valve correspondingly, ensure that the fan operates with lower rotational speed, when guaranteeing to indoor refrigeration effect, can finally make the difference in temperature value of body surface temperature and air-out temperature maintain at preset temperature to make the human body acquire better refrigeration and experience.

It should be noted that, for the air conditioning system, the air conditioning system includes a compressor, a condenser, an electronic expansion valve and an evaporator connected in sequence in a closed loop circuit by refrigerant pipes. The fan shown in the embodiment is preferably a cross-flow fan, and the airflow blown by the cross-flow fan is conveyed to the room after passing through the evaporator, so that the indoor temperature can be adjusted.
When the air conditioner starts to refrigerate, although the compressor runs at the temperature of the external environment according to the set frequency, when the opening degree of the electronic expansion valve is increased, the exhaust temperature of the compressor is reduced, the temperature of the refrigerant in the evaporator is at a higher temperature value, and therefore the outlet air temperature of the air conditioner is increased. Meanwhile, when the rotating speed of the fan is increased to the maximum value, although the air outlet temperature of the air conditioner is not particularly cool, the evaporation speed of sweat on the surface of a human body can be ensured by the high air speed, and the high heat exchange speed of the surface layer of the human body is still ensured while pores are not closed, so that the cool feeling of a user is ensured.

Here, the first opening degree, the second opening degree, and the third opening degree are set in the present embodiment to represent the adjustment trend of the opening degree of the electronic expansion valve.
Preferably, in this embodiment, the body surface temperature and the outlet air temperature are obtained when the air conditioner is turned on for a preset duration; wherein the preset time is 3-5 min. For example: the preset time period may be 3 minutes, 3 minutes and 30 seconds, 4 minutes or 5 minutes, and the like, and is not particularly limited herein.
Specifically, when the air conditioner initially started to refrigerate, probably the user was in still is in the motion state to and the evaporimeter probably still is in normal atmospheric temperature state, and this embodiment opens when predetermineeing the duration at the air conditioner, acquires user's body surface temperature and air conditioner's air-out temperature respectively, is favorable to ensureing the accuracy of the temperature data who obtains.
