In order to solve the above-mentioned technical problems, as shown in fig. 1 to 4, an embodiment of the present invention provides an air conditioner, the roof type air conditioner including: the air conditioner comprises a shell 1, wherein a partition plate 2 and a heat exchanger 3 are installed in the shell 1, the heat exchanger 3 is installed at a heat exchange opening of the partition plate 2, the shell 1 is divided into two chambers by the partition plate 2 and the heat exchanger 3, one chamber is communicated with an air inlet 4, the other chamber is communicated with an air supply outlet 5, specifically, a fan 15 and a motor for driving the fan 15 to rotate are installed at a position, close to the air supply outlet 5, in the chamber, and the fan 15 accelerates the air flow in the shell 1 under the action of the motor; a bypass air valve 6 is arranged on the partition plate 2, and the bypass air valve 6 is selectively communicated between the two chambers; preferably, the bypass air valve 6 is arranged as a pressure relief bypass air valve 6; as shown in fig. 2, preferably, the bypass damper 6 is installed at one side of the heat exchanger 3, and the total cross-sectional area of the ventilation channel of the bypass damper 6 is smaller than that of the ventilation channel of the heat exchanger 3, so as to ensure that the normal temperature air passing through the bypass damper does not affect the cooling or heating effect of the heat exchanger; in order to separate the condensed water, a water baffle 10 is further arranged on one side of the heat exchanger 3 close to the air supply opening 5, preferably, the shape of the water baffle 10 is matched with that of the heat exchanger 3, in order to ensure the air flowing effect, no resistance part is arranged between the bypass air valve 6 and the air supply opening 5, and the air flowing out through the bypass air valve 6 can directly flow into the room through the air supply opening 5.

Among the prior art, the air conditioner can't realize the accurate regulation to indoor air supply temperature, leads to the intelligent level of operation of air conditioner lower, influences the comfortable nature experience sense that the user used the air conditioner.
FIG. 5 is a schematic flow chart of a control method of the present invention;
the control method provided by the embodiment of the invention comprises the following steps:
step S1, if an operation mode instruction generated in response to user operation is received, controlling the heat exchanger to work according to the operation mode instruction;
specifically, the operation mode command is one of a ventilation mode, a refrigeration mode or a heating mode; for example, if the ventilation mode is generated in response to the user operation, the heat exchanger 3 is turned off, and similarly, if the cooling or heating mode is generated in response to the user operation, the heat exchanger 3 is turned on to perform the cooling or heating operation.
Step S2, determining a target deflection angle of the bypass air valve 6 according to the deflection angle adjusting strategy of the bypass air valve 6;
and step S3, controlling the bypass air valve 6 to work according to the target deflection angle.
If receiving a cooling or heating mode generated in response to a user operation, the deflection angle adjustment strategy of the bypass air valve 6 comprises the following steps:
within a preset time period t, if the absolute value of the current temperature difference value is detected to be smaller than the threshold value of the preset temperature difference value, calculating the current opening value of the bypass air valve according to the detected current indoor temperature value and the following formula:
wherein, M is the current opening value of the bypass air valve 6, Tf is the current indoor temperature value, Ts is the preset indoor temperature value, and Δ T is the preset temperature difference value.
Preferably, the value range of M is 0-100; tf ranges from-10 to 100 ℃; the value range of Ts is 15-40 ℃; the value range of delta T is 1-30 ℃, the value range of the preset time T is 1-120 min, and preferably, T is set to be 5 min.
And if the absolute value of the current temperature difference value is detected to be larger than the preset temperature difference value threshold value, setting the current opening value of the bypass air valve 6 to be 0.
The target deflection angle of the bypass damper 6 is calculated according to the following formula:
α＝0.9M；
where α is a target deflection angle of the bypass damper 6, and M is a current opening value of the bypass damper 6.
The value range of M is 0-100, so that the value range of alpha is 0-90 ℃, namely when the deflection angle of the air guide blade 8 of the bypass air valve 6 is 0 ℃, the bypass air valve 6 is completely closed, and when the deflection angle of the air guide blade 8 of the bypass air valve 6 is 90 ℃, the bypass air valve 6 is completely opened.
Illustratively, the heating mode is exemplified below, the preset indoor temperature value Ts is 25 ℃, the preset temperature difference value Δ T is 2 ℃, and the preset operation time T of the air conditioner is 5 min; specifically, after the preset operation time of the air conditioner is 5min, detecting the current indoor temperature value in real time, if the detected current indoor temperature value Tf is 30 ℃, obtaining that the absolute value of the current temperature difference value is 3 ℃, and because the absolute value of the current temperature difference value obtained by calculation is greater than the preset temperature difference value Δ T, indicating that the indoor temperature does not reach the indoor temperature required by the user at the moment, setting the current opening value of the bypass air valve 6 to be 0, correspondingly, determining that the target deflection angle of the bypass air valve 6 is 0 ℃, and at the moment, only closing the bypass air valve 6, and only performing heating operation on all air flowing in through the air inlet 4 through the evaporator to meet the requirements of the user; on the contrary, if it is detected that the current indoor temperature value Tf is 24 ℃, it may be determined that the absolute value of the current temperature difference value is 1 ℃, since the calculated absolute value of the current temperature difference value is smaller than the preset temperature difference value Δ T, it indicates that the indoor temperature is close to the preset indoor temperature at this time, and the amount of demand of the user for hot air is reduced, it correspondingly sets the current opening value of the bypass air valve 6 to 50, and correspondingly determines that the target deflection angle of the bypass air valve 6 is 45 ℃, at this time, the driving component 7 of the bypass air valve 6 deflects the plurality of air guide vanes 8 by the linkage connecting rod 9 in the direction away from the opening by 45 ℃ to open the opening, thereby realizing the separation of the air flowing in through the air supply opening 5 into two parts, wherein one part of the air flows to the air supply opening 5 after being heated by the heat exchanger 3, while the other part of the air flows directly to the air supply opening 5, and finally the two parts of the air form mixed air lower than the cold air at the air supply opening, therefore, the heat exchange quantity is reduced, the air supply temperature is increased, the indoor temperature comfort is ensured, and the intelligent energy-saving level of the air conditioner is effectively improved.
In addition, in conclusion, by adjusting the opening value of the bypass air valve 6, the air flow passing through the bypass air valve 6 can be adjusted, so that the air flow passing through the resistance components such as the heat exchanger 3 and the water baffle plate 10 is effectively reduced, and the flow pressure loss in the machine is reduced.
Similarly, the refrigeration mode is the same as the above-mentioned adjustment process, and will not be described herein in detail.
If the ventilation mode generated in response to the user operation is received, the deflection angle adjusting strategy of the bypass air valve 6 comprises the following steps:
the current opening value of the bypass damper 6 is set to 100%.
The target deflection angle of the bypass damper 6 is calculated according to the following formula:
α＝0.9M；
where α is a target deflection angle of the bypass damper 6, and M is a current opening value of the bypass damper 6.
Correspondingly, alpha is 90 ℃, namely in a ventilation mode, the air guide blade 8 of the bypass air valve 6 deflects to a direction far away from the opening by 90 ℃ under the action of the driving assembly 7 so as to open the bypass air valve 6 to the maximum value, at the moment, a large amount of air preferentially flows to the air supply opening 5 through the bypass air valve 6, and finally a small part of air flowing out through the heat exchanger 3 is mixed with the air and flows out of the shell 1, so that the resistance of the air in the flowing process in the shell 1 is effectively reduced, the running load of the fan 15 and a matched motor is reduced, the running efficiency is improved, and the service life of the air conditioner is finally prolonged.
