Example Embodiment
[0051] Example 1
[0052] Such as Figure 1-4 As shown, the present invention provides an air conditioner (preferably an air source heat pump in the present invention) 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. Switch between the two operation modes, and the control system includes:
[0053] Detection unit for detecting indoor ambient temperature T Inner ring ;
[0054] Judgment unit, used to calculate △T=|T Inner ring -T set up |, and judge △T≤T 1 Established or not, where T set up Set the temperature for the air-conditioning room, T 1 It is the set value, which can be any positive number;
[0055] The control unit is used to select a low output operation mode or a high output operation mode to operate the air conditioner according to the judgment result of the judgment unit.
[0056] By detecting the indoor ambient temperature T Inner ring 、Calculate...
Example Embodiment
[0060] Example 2
[0061] Preferably, the low-output operation mode includes at least one of the air outlet micro-hole type, the windshield is reduced by at least one gear, and the compressor operating frequency is reduced; the micro-hole air outlet of 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 micropore can be equal or unequal; the shape of the micropores can be round, elliptical, polygonal, irregularly shaped holes, or a combination of the above shapes , The same below.
[0062] The high-output operation mode includes at least one adjustment mode of an air outlet guide vane type or a guide air grille type, a windshield raised by at least one gear, and a compressor operating frequency raised.
[0063] Any one or a combination of the air outlet micro-hole type, windshield reduction at least one gear, and compressor operating frequency reduction is used as a low output operation mode,...
Example Embodiment
[0065] Example 3
[0066] Preferably, after the control unit selects the low output operation mode,
[0067] The judging unit is also used for judging △T=0℃ (Supplement: △T=|T Inner ring -T set up |Theoretically also need to detect real-time T Inner ring 的) is established, and (T Inner ring 1 -T Inner ring 2 ) / △t=0℃ / min is established,
[0068] Where: T Inner ring 1 Is the inner ring temperature detected at time t, T Inner ring 2 It is the inner ring temperature detected at time t+△t.
[0069] After the control unit selects the low-output operation mode, the judging unit is also used to judge whether △T=0℃ holds, and (T Inner ring 1 -T Inner ring 2 ) / △t=0℃ / min is established, can judge T Inner ring (Indoor ambient temperature) Has it reached T set up (Indoor set temperature), and whether there is still a non-zero temperature change rate, which can effectively and accurately determine whether the indoor ambient temperature can accurately reach and stabilize at the set temperatur...
