In above-mentioned technical scheme, cold refrigeration mode and freezing refrigeration mode can be with indoor temperature reduction to the air conditioner conventional settlement temperature minimum below. In the two cooling modes, the set temperature of the air conditioner is not controlled by a user, namely, the air conditioner can reduce the indoor temperature to the lowest temperature which can be reached by the air conditioner, and other intelligent control functions which can influence the cooling effect are not started. However, since the windshield of the indoor unit directly affects the noise of the indoor unit, after the cold refrigeration mode and the freezing refrigeration mode are started, the windshield of the air conditioner is controlled by a user, and the reduction of the windshield can cause the reduction of the refrigeration effect (generally, the operation frequency of a mute gear of the air conditioner is lower than that of an ultra-strong gear, and the reduction of the windshield by the user also reduces the operation frequency, so that the refrigeration effect is reduced here).
As can be seen from the above, the cold cooling mode and the freezing cooling mode may cause the indoor temperature to be lowered to a temperature that may not be desired by the user, so the opening manner needs to be complicated to prevent the user from catching a cold after being opened by accident. The invention adopts a mode of reducing the set temperature for the air conditioner for a plurality of times in a short time under special conditions, namely a mode of reducing the set temperature to be lower according to the intention of a user.
In the cold refrigeration mode, the indoor temperature can be reduced to the air outlet temperature of the air conditioner, and the refrigeration effect of each air conditioner is different; in the dynamic refrigeration mode, under the condition that the refrigeration effect is not changed, the heat exchange of the internal machine is deteriorated, the temperature in the evaporator is further reduced to be below 0 ℃, the surface of the evaporator is frosted, and the indoor temperature can be reduced to the air outlet temperature of the air conditioner.
For more convenient use cold refrigeration mode and freeze the refrigeration mode, cold refrigeration mode start temperature and freeze refrigeration mode start temperature have been set up. The set temperature is set to be the cold refrigeration mode starting temperature or the freezing refrigeration mode starting temperature, and then the cold refrigeration mode or the freezing refrigeration mode can be entered. When the mode is adopted to enter the cold refrigeration mode or the freezing refrigeration mode, the indoor temperature is reduced to the cold refrigeration mode starting temperature or the indoor temperature can not be further reduced after the freezing refrigeration mode starting temperature is reduced. Like this at the preliminary use cold refrigeration mode or freeze the refrigeration mode after, the user can be with feeling suitable temperature, set for cold refrigeration mode starting temperature or freeze refrigeration mode starting temperature, just so can directly set for the air conditioner refrigeration to reduce to cold refrigeration mode starting temperature or freeze refrigeration mode starting temperature to indoor temperature, can not further reduce indoor temperature to avoid cold or excessive refrigeration.
The invention has the following beneficial effects:
1. the indoor temperature can be reduced to be below the lowest value of the conventional set temperature, and the requirements of users on various aspects of refrigeration are met;
2. by setting the starting temperature, the common refrigeration target temperature can be added to the set temperature range, so that excessive refrigeration is not caused.

Detailed Description
In order to more clearly illustrate the technical solutions of the present invention, the following description is given with reference to specific embodiments and accompanying drawings, and it is obvious that the embodiments in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other embodiments can be obtained according to these embodiments without any inventive work.
Example 1
The embodiment relates to two control methods of the refrigeration mode of an air conditioner and the air conditioner capable of executing the two control methods. The two air conditioner refrigeration mode control methods are respectively a cold refrigeration mode and a freezing refrigeration mode, and the flow charts of the control methods of the two modes are shown in fig. 1. Wherein, the normal set temperature range of the air conditioner is 16-30 ℃, and the minimum set temperature is 16 ℃.
As shown in fig. 1, in the present embodiment, the control flow of the cold cooling mode is as follows:
(1) starting the air conditioner, and adjusting the set temperature: the user turns on the air conditioner and adjusts the set temperature using the remote controller.
(2) Entering a cold refrigeration mode: if the user feels not cold enough and wants the air conditioner to further lower the indoor temperature after the set temperature is turned down to 16 c, the windshield is turned to the highest windshield and the button for turning down the set temperature is pressed five or more times within 3 s. When the set temperature is adjusted to 16 ℃, the air conditioner starts timing every time the air conditioner receives a request for adjusting the set temperature downwards, and records the times of receiving the request for adjusting the set temperature downwards after timing is started. When the number of times that the air conditioner receives the request for reducing the set temperature within the timing time of 3s is more than or equal to five times, judging whether the wind speed of the fan is the highest wind speed, and if the wind speed of the fan is not the highest wind speed, operating the air conditioner according to the original state; and if the wind speed of the fan is the highest wind speed, entering a cold refrigeration mode.
(3) The wind speed of the fan is automatically adjusted, and the fan is forced not to stop: under cold refrigeration mode, the set temperature of air conditioner is automatically adjusted to the set temperature minimum, and the fan wind speed is automatic to be moved with the highest wind speed to ignore indoor environment temperature sensing package's detection data, even the indoor temperature that detects reduces to the set temperature minimum, can not reduce compressor operating frequency or shut down yet. Meanwhile, the display displays the indoor temperature.
(4) The user adjusts the wind speed of the fan: the user can adjust the wind speed of the fan through the remote controller. In the cold refrigeration mode, if the air conditioner receives a request of a user for adjusting the wind speed of the fan, the wind speed of the fan can be adjusted according to the request.
(5) Preservation of cold refrigeration mode starting temperature: in the cold refrigeration mode, the display shows the indoor temperature. The cold cooling mode reduces the indoor temperature to a minimum value that can be reduced, for example, 9 ℃. When the user feels the temperature is proper, the remote controller requests to store the temperature of 12 ℃ displayed by the display at the moment as the cold refrigeration mode starting temperature. And after the air conditioner receives the request of storing the temperature of 12 ℃ as the cold refrigeration mode starting temperature, storing the temperature of 12 ℃ as the cold refrigeration mode starting temperature. The cold refrigeration mode starting temperature can be set to one or more.
(6) Entering a freezing and refrigerating mode: if the user wishes to lower the indoor temperature further, the button for down-regulating the set temperature may be pressed within 3s five or more times in the cold cooling mode. In the cold cooling mode, the air conditioner starts timing every time the air conditioner receives a request for adjusting the set temperature downwards, and records the times of receiving the request for adjusting the set temperature downwards after the timing is started. And entering a freezing and refrigerating mode when the number of times of receiving the request for adjusting the set temperature downwards within the timing 3s is more than or equal to five times.
(7) Automatically reducing the wind speed of the fan and increasing the working frequency: the air conditioner detects the temperature difference delta T between the indoor temperature detected by the indoor environment temperature sensing bulb and the surface temperature of the copper pipe detected by the indoor unit copper pipe surface temperature sensing bulb. Judging whether delta T is less than or equal to 1 ℃, and if delta T is more than 1 ℃, operating according to a cold refrigeration mode; if delta T is less than or equal to 1 ℃, the wind speed of the fan automatically runs at the lowest windshield, and the working frequency of the compressor automatically runs at the highest frequency.
(8) The user adjusts the wind speed of the fan: the user can adjust the wind speed of the fan through the remote controller. In the freezing and refrigerating mode, if the air conditioner receives a request of a user for adjusting the wind speed of the fan, the wind speed of the fan can be adjusted according to the request.
(9) Preserving the starting temperature of the freezing and refrigerating mode: in the freezing and cooling mode, the display displays the indoor temperature. The freeze cooling mode reduces the indoor temperature to a minimum value that can be reduced, for example, -3 ℃. When the user feels the temperature is proper, the remote controller requests to store the temperature 3 ℃ displayed by the display at the moment as the starting temperature of the freezing and refrigerating mode. And after receiving the request of storing the temperature of 3 ℃ as the starting temperature of the freezing and refrigerating mode, the air conditioner stores the temperature of 3 ℃ as the starting temperature of the freezing and refrigerating mode. The freezing refrigeration mode starting temperature can be set to one or more temperatures.
(10) And (4) exiting the freezing and refrigerating mode: when the user wants to end the freezing and cooling mode, a request for adjusting the set temperature up can be sent to the air conditioner by pressing a button for adjusting the set temperature up by the remote controller. In the freezing and refrigerating mode, if the air conditioner receives a request for adjusting the set temperature up, the air conditioner exits the freezing and refrigerating mode.

In this embodiment, the next operation is performed based on embodiment 1, as shown in fig. 2:
(1) starting the air conditioner: the user turns on the air conditioner.
(2) Entering a cold refrigeration mode: the user can select or adjust the set temperature to the cold refrigeration mode starting temperature of 12 ℃ through the cold refrigeration mode in the special mode. The set temperature of the air conditioner is adjusted to be 12 ℃ in the cold refrigeration mode starting temperature, and the air conditioner enters the cold refrigeration mode.
(3) The control temperature is kept near the cold refrigeration mode starting temperature: if the cold refrigeration mode is entered because the set temperature is adjusted to 12 ℃ as the starting temperature of the cold refrigeration mode, the air conditioner adjusts the wind speed of the fan and the frequency of the compressor when the indoor temperature is reduced to 12 ℃, and the indoor temperature is not reduced any more.
(4) And (4) exiting the cold refrigeration mode: when the user wants to end the cold cooling mode, the user can send a request for adjusting the set temperature to the air conditioner by pressing the button for adjusting the set temperature to the remote controller. In the cold cooling mode, if the air conditioner receives a request for adjusting the set temperature up, the air conditioner exits the cold cooling mode.
