Embodiment 1

[0029] The invention provides a control method for improving cooling comfort of an inverter air conditioner, which combines figure 1 As shown, the control method for improving the refrigeration comfort of the inverter air conditioner includes

[0030] In the cooling mode, if the air conditioner is shut down because the indoor temperature reaches the temperature point, and the air conditioner has a cooling temperature compensation function, a dynamic compensation operation is performed.

[0031] Specifically, the control method for improving cooling comfort of an inverter air conditioner includes the following steps:

[0032] S11: judging whether the shutdown of the air conditioner in cooling mode means that the indoor temperature reaches the temperature point;

[0033] The temperature point specifically refers to the actual shutdown temperature of the air conditioner;

[0034] S12: If yes, continue to judge whether the air conditioner has a cooling temperature compensation f...

Embodiment 2

[0049] As described above, the control method for improving cooling comfort of an inverter air conditioner is different from this embodiment in that in S12, it is judged that the shutdown of the air conditioner in the cooling mode is not because the indoor temperature reaches the temperature point, and then proceeds. Protection shutdown processing; the protection shutdown specifically includes: after the shutdown time A of the air conditioner, the air conditioner resumes operation, and it will not resume after repeated shutdowns for N times, and it needs to be restarted by remote control; wherein, A>0s; N≥1 .

[0050]Preferably, in this embodiment, the shutdown time A is selected as 60s, and the number of repeated shutdowns N is preferably 6 times.

Embodiment 3

[0052] As described above, the control method for improving the cooling comfort of the inverter air conditioner, the difference of this embodiment is that in the above S13, if the air conditioner is shut down in the cooling mode, the indoor temperature reaches the temperature point, and the air conditioner If it does not have the cooling temperature compensation function, then stop processing at the point where the temperature reaches the temperature; the shutdown at the point where the temperature reaches the temperature specifically includes: the fan in the air conditioner continues to run, the air guide door remains open, the compressor stops running, and when the indoor ambient temperature When the temperature difference ΔT≥0°C from the set temperature of the remote controller, the compressor is restarted.

Abstract

The invention provides a control method for improving the refrigeration comfort of a frequency conversion air conditioner, and relates to the technical field of air conditioners. The control method for improving the refrigeration comfort of the frequency conversion air conditioner comprises the following steps that in a refrigeration mode, if the air conditioner shuts down since the indoor temperature reaches the temperature point and the air conditioner has the refrigeration temperature compensation function, the dynamic compensation operation is conducted, wherein according to the specific dynamic compensation operation, the dynamic compensation value delta t DEG C is added for the refrigeration temperature compensation value on the basis of the fixed compensation value. The provided control method for improving the refrigeration comfort of the frequency conversion air conditioner can solve the problem that frequent shutdown is likely to happen due to low loads, wherein the problem cannot be solved through the fixed refrigeration temperature compensation value; and the problem that in the refrigeration mode, the temperature point is reached, and sudden cold and heat happen due torepeated startup and shutdown is solved, and the usage comfort of users is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method for improving cooling comfort of an inverter air conditioner. Background technique [0002] Theoretically speaking, as the difference between the actual indoor ambient temperature and the temperature set by the remote controller △T℃ decreases, the frequency of the inverter air conditioner will gradually decrease to the minimum operating frequency. If the output cooling load of the minimum operating frequency is still higher than that of the indoor cooling Load demand, if the indoor temperature continues to drop, it may cause shutdown, and restart after the temperature rises. The air conditioner is repeatedly turned on and off, causing users to feel uncomfortable in hot and cold. [0003] At present, in order to solve the problem of repeated start-up of the air conditioner, conventional methods include reducing the lower limit of the minimum operating fr...
