Description

Method and device for correcting ambient temperature in air conditioner and air conditioner
Technical Field
The invention relates to the technical field of air conditioner control, in particular to a method and a device for correcting the ambient temperature in an air conditioner and the air conditioner.
Background
The split air conditioner mainly controls the performance and reliability of the whole machine by controlling temperature and pressure. The indoor environment temperature is the basis and basis for controlling the air conditioner control system, and plays an important role in the detection accuracy and the reliable control of the air conditioner system and the optimal operation of the system.
Theoretically, the average temperature of each space point in a room, the room center temperature, or the air supply area center temperature is suitable as the indoor environment temperature in the air conditioner temperature control system. The indoor unit of the air conditioner is installed at the corner of a room in a family of users, the temperature sensing bulb for detecting the indoor environment temperature is generally installed at the lower position of the back of the indoor unit, below the evaporator part and in the water receiving disc clamping groove and is about half a meter away from the ground. In the position, the temperature detected by the temperature sensing bulb is the local room temperature at the corner of the room, and the deviation degree of the detected temperature and the actual indoor environment temperature is different under different working modes.
In order to achieve the refrigeration effect that the air conditioner can refrigerate quickly after being started and cold air does not blow people after the temperature is reduced, the refrigeration air-out logic of the air conditioner is determined as follows: after the machine is started, the upper air opening and the lower air opening simultaneously exhaust air, so that the indoor environment temperature is rapidly reduced. When the room temperature is reduced to the target temperature range, the air outlet angle of the upper air deflector is raised while the air is exhausted from the single upper air outlet, so that cold air forms a closed cycle in the whole indoor space, and the main moving area of the human body is surrounded by the cold air shape line. The air conditioner body provided by the patent is higher, the upper air outlet form is top air supply, and in the air outlet mode, when the air deflector is lifted to a larger angle, the air outlet blows to the ceiling, partial cold air is reflected to the periphery of the air conditioner and is sucked into the air inlet. Thus, the air outlet and the air inlet generate mixed flow, and the temperature of the temperature sensing bulb at the intersection of the air inlet and the air outlet is directly influenced. Originally, the temperature of the thermal bulb has deviation from the indoor environment temperature and needs the first layer of correction, and the phenomenon of mixed flow of air inlet and air outlet is added, so that the logic correction from the aspects of air flow and heat transfer is complex, and the stability of temperature correction is difficult to ensure.
In addition, in the related art, there are two processing schemes for the failure of the indoor environment temperature sensor: scheme 1: when the indoor environment temperature sensor fails, the air-conditioning electric control system detects the failure of the indoor temperature sensor, the air-conditioning system stops, the failure is displayed on a panel, and a user is reminded that a prototype needs to be maintained; scheme 2: a plurality of indoor environment temperature sensors are arranged on the indoor unit of the air conditioner, the scheme 1 is improved, and the use of a user can be ensured. When one of the indoor environment temperature sensors has a fault, the air conditioner can call other indoor temperature sensors to obtain the indoor environment temperature, so that the air conditioner can maintain a normal operation state. The two processing modes have the defects that the design of the scheme 1 is not intelligent and humanized enough, and the cost of the scheme 2 is higher.
In view of the above problems, no effective solution has been proposed.
