Embodiment 1

[0052] Such as Figure 1-4 As shown, the present invention provides an air conditioner (the present invention is preferably an air source heat pump) control system, the air conditioner includes a low output operation mode with relatively low output energy and a high output operation mode with relatively high output energy, and the air conditioner can Switch between the two operating modes, and the control system includes:

[0053] A detection unit for detecting the indoor ambient temperature T 内环 ;

[0054] Judgment unit, used to calculate △T=|T 内环 -T 设定 |, and judge that △T≤T 1 established or not, where T 设定 Set temperature for the air-conditioned room, T 1 is the set value, which can be any positive number;

[0055] The control unit is used for selecting a low output operation mode or a high output operation mode to operate the air conditioner according to the determination result of the determination unit.

[0056] By detecting the indoor ambient temperature T 内环 ,...

Embodiment 2

[0061] Preferably, the low-output operation mode includes at least one adjustment mode in the air outlet micro-hole type, the windshield is lowered by at least one gear, and the operating frequency of the compressor is reduced; the micro-hole air outlet in the present invention refers to the diameter or axial direction of the hole For holes with a length ranging from 0.5 to 50mm, the size of each microhole can be equal or unequal; the shape of the microholes can be circular, oval, polygonal, irregularly shaped, or a combination of the above shapes , the same below.

[0062] The high-output operation mode includes at least one of the adjustment modes of air guide vane type or air guide grille type at the air outlet, windshield raised by at least one gear, and compressor operating frequency increased.

[0063] By using any one or combination of micro-holes in the air outlet, lowering the windshield by at least one gear, and reducing the operating frequency of the compressor as a...

Embodiment 3

[0066] Preferably, after the control unit selects the low output operation mode,

[0067] The judging unit is also used to judge ΔT=0°C (supplement: ΔT=|T 内环 -T 设定 |In theory, it is also necessary to detect real-time T 内环 of) is established, and (T 内环1 -T 内环2 ) / △t=0℃ / min is established,

[0068] Among them: T 内环1 is the inner ring temperature detected at time t, T 内环2 is the inner ring temperature detected at time t+△t.

[0069] After the control unit selects the low output operation mode, the judgment unit is also used to judge whether ΔT=0°C is established, and (T 内环1 -T 内环2 ) / △t=0℃ / min can be judged whether T 内环 (indoor ambient temperature) has reached T 设定 (indoor set temperature), and whether there is a temperature change rate that is not zero, so that it can effectively and accurately determine whether the indoor ambient temperature can accurately reach and stabilize at the set temperature, which is the air conditioning control system and method of the present ...

Abstract

The invention provides an air-conditioner control system and a control method thereof; the air-conditioner comprises a low output running mode with relatively low output energy and a high output running mode with relatively high output energy; the air conditioner can be mutually switched between two running modes, and the control system comprises a detecting unit, a judging unit, and a control unit. The detecting unit is used for detecting an inner ring of indoor environment temperature T; the judging unit is used for calculating the inner ring-T setting I of delta T=IT, and judging if delta T is not more than T1, wherein T is set as the indoor setting temperature of the air conditioner, T 1 is setting value and any positive number; the control unit can run the air condition in low output running mode or high output running mode according to the judging result of the judging unit. Through the invention, the room temperature can slowly change when closing to the T setting scale, prevent exceeding the setting temperature for too fast drop or rise of room temperature, avoid frequent startup of compressor, effectively prevent fluctuation of indoor environment temperature, and improve the comfort level of the indoor environment.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning control system and a control method thereof. Background technique [0002] At present, when the traditional air source heat pump system has a small indoor environmental load (cooling), it is easy to cause the indoor ambient temperature to reach the set temperature and cause the compressor to stop. In this state, the indoor ambient temperature will gradually decrease due to the compressor shutdown. After a certain condition is reached, the compressor starts to run again for cooling; in this case, the compressor will start and stop frequently, and the indoor ambient temperature will fluctuate accordingly, which will not only affect the service life of the compressor, but also affect the comfort of the user Spend. [0003] Since the air source heat pump system in the prior art is prone to technical problems such as frequent start and stop of...
