Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
At present, the treatment mode for preventing the water blowing phenomenon is single, and after the refrigeration mode or the dehumidification mode is shut down, the four-way valve is adopted for reversing, and the indoor heating mode is adopted for evaporating the components in the indoor unit such as an evaporator. However, under different conditions, the amount of condensed water generated by the indoor unit is different, even the condensed water cannot be generated under certain conditions, and the phenomenon of water blowing cannot occur when the indoor unit is started again. And the single heating mode of preventing blowing water can improve the consumption of electric energy and cause unnecessary resource waste.
The embodiment provides a method for controlling anti-blowing water, which is shown in fig. 1 and includes the following steps:
step S1, when the air conditioner runs in a cooling mode or a dehumidifying mode, recording the continuous running time of the compressor; specifically, when the air conditioner operates in a cooling mode or a dehumidifying mode, the internal temperature of the indoor unit is low, and when the air conditioner is turned off, heat of the external environment of the indoor unit enters the indoor unit and contacts with cold air to generate condensed water; the output of the condensed water is gradually increased along with the increase of the contact time; the embodiment limits the operation of the anti-blowing control method in a dehumidification or refrigeration mode, and judges the conditions which are easy to generate condensed water more accurately; when the air conditioner operates in a refrigeration mode or a dehumidification mode, specifically, the continuous operation time length refers to the total execution time length when the compressor is not stopped, and when the compressor is stopped due to shutdown or reaching a set temperature, the execution time length of the compressor is recorded again; preferably, the embodiment records the continuous operation time of the compressor in real time; if the air conditioner is converted into a heating mode in the operation process of the refrigeration mode or the dehumidification mode, quitting recording the continuous operation time length of the compressor; until the air conditioner operates in the cooling mode or the dehumidification mode again, the continuous operation duration of the compressor refers to the continuous operation duration of the compressor which is executed once when the air conditioner operates in the cooling mode or the dehumidification mode;
step S2, when the air conditioner is shut down, the compressor is closed; specifically, the air conditioner is shut down, and usually, the air conditioner receives a shutdown signal sent by a remote control device; when the air conditioner is shut down, the compressor is closed, and the four-way reversing valve and other devices are closed.
Step S3, determining to execute a water blowing prevention action according to the last continuous operation time length, wherein the last continuous operation time length is the last continuous operation time length before the air conditioner is turned off; specifically, the anti-blowing action has multiple execution actions, different execution actions have different power consumptions, and the efficiency of eliminating condensed water is different.
It should be noted that the last continuous operation duration refers to the last continuous operation duration of the compressor in the refrigeration mode or the dehumidification mode before the shutdown, and since the compressor may be stopped when the air conditioner reaches the set temperature in the refrigeration mode or the dehumidification mode, a plurality of continuous operation durations may be recorded during the operation of the air conditioner in the refrigeration mode or the dehumidification mode, which is adopted in this embodiment as the last continuous operation duration before the shutdown; if the compressor is not stopped in the whole process, the last continuous operation time before the shutdown is the whole continuous operation time of the compressor.
Specifically, the anti-blow operation execution modes in the present embodiment include three types:
the first water blowing prevention action is used for controlling the opening angle of the air guide door to a preset angle and lasting for a first time length;
the second water blowing prevention action is performed, the opening angle of the air guide door is controlled to a preset angle, air is discharged in a mute manner, and the second time duration is continued;
and the third prevention of water blowing action controls the opening angle of the air guide door to a preset angle, mute air outlet and start electric heating, and lasts for the third time.
Generally, the length of the operation time of the compressor cooling mode or the dehumidifying mode is directly related to the temperature reduced inside the indoor unit, and the smaller the degree of temperature reduction inside the indoor unit is, the less condensed water is generated. According to the invention, the continuous operation time of the compressor is judged, the execution mode of starting the anti-blowing action is determined, the most energy-saving execution mode is selected, and unnecessary energy waste is reduced.
