Detailed Description
The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and the detailed description.
The embodiment provides a method for improving the comfort level of an air conditioner in the defrosting process, which is used for improving the indoor comfort level of the air conditioner in the defrosting process and reducing the adverse effect on a human body.
The air conditioner comprises a shell, and a fan, an indoor heat exchanger and an electric heater which are positioned in the shell. The shell is provided with an air inlet and an air outlet, the air inlet is provided with an indoor temperature sensor, the air outlet generally and directly faces the indoor space, and the air inlet does not directly face the indoor space. When the air conditioner normally refrigerates and heats, the rotation direction of the fan is defined to be positive rotation, at the moment, airflow flowing from the air inlet to the air outlet is formed in the shell, so that the airflow which is subjected to heat exchange with the indoor heat exchanger flows indoors through the air outlet, and the indoor environment temperature is adjusted. The shape of the air conditioner is not limited in the present invention.
The following describes a method for improving the comfort level of the air conditioner during the defrosting process.
And judging whether the conditions for entering defrosting are met or not in the operation heating process of the air conditioner. When heating, the fan forward rotates, forms the air current from air intake flow direction air outlet in the casing, and the air current in the casing directly flows to the interior space from the air outlet, adjusts the temperature of interior space. The present embodiment does not limit the condition for entering the defrost mode, and may be the existing condition for entering the defrost mode.
If the defrosting condition is met, the fan is controlled to rotate reversely, so that air flow flowing from the air outlet to the air inlet is formed in the shell, and the electric heater is started. When the electric heater is just started with smaller power, the fan rotates reversely to form lower-temperature airflow flowing from the air outlet to the air inlet in the shell, indoor air flows into the shell from the air outlet, the air outlet cannot naturally emit cold air, the lower-temperature airflow in the shell flows out from the air inlet, the temperature influence on the indoor space is smaller, and people in the indoor space cannot feel the cold air. When the power of the electric heater is gradually increased to proper power, the fan rotates reversely to form airflow with higher temperature flowing from the air outlet to the air inlet in the shell, and the airflow with higher temperature in the shell flows out of the air inlet and gradually enters the indoor space to further increase the temperature of the indoor space. Therefore, the air outlet can be prevented from generating cold air in the defrosting process, the room temperature can be improved under the action of electric heating, and the comfort level in the defrosting stage is improved.
And judging whether the defrosting condition is met or not in the defrosting process of the air conditioner. The defrosting exit condition is not limited in this embodiment, and may be an existing defrosting exit condition.
If the defrosting condition is met, the fan is controlled to rotate in the positive direction, so that air flow flowing from the air inlet to the air outlet is formed in the shell, and the air conditioner normally runs in a heating mode.
In order to increase the indoor temperature as soon as possible in the defrosting process, when the condition of entering defrosting is met, an indoor temperature sensor detects the indoor temperature at the moment, and the indoor temperature is defined as the indoor temperature before entering defrosting; after defrosting is carried out, the indoor temperature sensor detects the indoor temperature during defrosting in real time or at regular time, if the indoor temperature during defrosting is higher than the indoor temperature before defrosting, at the moment, the heat generated by the electric heater is greater than the cold quantity generated by the indoor heat exchanger, and the temperature of the air flow is higher than the indoor temperature before defrosting, the fan is controlled to rotate in the forward direction, so that the air flow flowing from the air inlet to the air outlet is formed in the shell, the indoor temperature is improved as soon as possible, and the indoor comfort level is further increased.
In order to be able to adjust the indoor temperature as quickly as possible and to save power, the power of the electric heater needs to be adjusted. And after defrosting is started, calculating the difference between the indoor temperature and the set temperature in real time, acquiring the outdoor environment temperature in real time, and adjusting the power of the electric heater according to the calculated difference and the outdoor environment temperature acquired in real time. The set temperature is the temperature set by the user, and the outdoor environment temperature is detected by the outdoor temperature sensor. The difference between the indoor temperature and the set temperature, the outdoor environment temperature and the power of the electric heater can be a list determined in advance through experiments, and the power of the electric heater can be determined through table lookup. The embodiment detects and controls the whole working process of the electric heater in real time so as to effectively reduce the power loss of the electric heater and ensure the comfort requirement of a user.
In order to achieve the effect of defrosting as soon as possible, after defrosting, the air conditioner detects the temperature of the outdoor coil in real time, and the rotating speed of the fan is controlled according to the temperature of the outdoor coil. The outdoor coil pipe temperature is provided with two temperature intervals at least, and every temperature interval corresponds a fan rotational speed respectively, and the fan rotational speed that the interval that the temperature is high corresponds is little, and the fan rotational speed that the interval that the temperature is low corresponds is big.
After entering the defrosting mode, the air conditioner displays the indoor temperature before entering the defrosting mode, and if the indoor temperature during the defrosting mode is higher than the indoor temperature before the defrosting mode, the air conditioner displays the indoor temperature during the defrosting mode.
As shown in fig. 1, the method for improving the comfort of the defrosting process of the air conditioner in the embodiment comprises the following steps:
and S1, operating the air conditioner in a heating mode.
S2, the air conditioner judges whether the condition for defrosting is satisfied, if yes, the step S3 is executed, otherwise, the step S1 is executed.
And S3, defrosting, detecting the indoor temperature before defrosting, controlling the fan to rotate reversely, and simultaneously starting the electric heater.
And S4, detecting the indoor temperature in defrosting in real time or at regular time by the indoor temperature sensor.
S5, judging whether the indoor temperature during defrosting is higher than the indoor temperature before defrosting, if so, entering step S6, otherwise, entering step S7.
And S6, controlling the fan to rotate in the positive direction.
And S7, when the defrosting condition is met, the air conditioner runs in a heating mode and controls the fan to rotate in the positive direction.
