Embodiment 1
[0027] see Figure 1-4 , a method for solving the noise of the external unit of the air conditioner, step 1: the air conditioner is turned on, and the compressor is turned on;
[0028] Step 2: The pressure sensor detects the internal pressure P of the compressor, and at the same time detects the suction temperature T through the suction temperature sensor;
[0029] Step 3: By calculating whether the suction superheat is negative (the suction superheat Tg=T-T1 (the saturation temperature corresponding to the detection suction pressure)), if the suction superheat is negative, the suction is liquid, and the compressor is detected synchronously Whether the internal pressure meets the pressure P≥PM for the separation of the sliding vanes (the separation force of the sliding vanes ≥ the pressing force of the sliding vanes);
[0030] Step 4: If it is satisfied, adjust the opening of the electronic expansion valve (only for the electronic expansion valve system), by closing the openi...

The invention relates to the technical field of noise elimination of the external unit of the air conditioner, and discloses a method for solving the noise of the external unit of the air conditioner. Detect the suction temperature T; Step 3: By calculating whether the suction superheat degree is negative, if the suction superheat degree is negative, the suction is filled with liquid, and synchronously detect whether the internal pressure of the compressor satisfies the pressure P≥PM for the separation of the vanes; Step 4 : If it is satisfied, adjust the opening of the electronic expansion valve. By closing the opening B, the exhaust and suction are increased, the suction superheat is increased, and the compressor pressure is reduced to ensure that the sliding vane does not detach; Step 5: If the electronic The opening of the expansion valve cannot reduce the compressor pressure to ensure that the vanes are not separated, control the compressor to increase the frequency F, quickly increase to the corresponding frequency, increase the exhaust and suction, increase the suction superheat, and reduce the compressor pressure. Satisfy P<PM to ensure that the slider does not detach.
Description
technical field [0001] The invention relates to the technical field of noise elimination of the external unit of an air conditioner, in particular to a method for solving the noise of the external unit of an air conditioner. Background technique [0002] With the development of the economy, people's living standards have been improved, the demand for air conditioners is also increasing, and the functions of air conditioners are also improving. Only the cooling and heating function can no longer meet the needs of customers. Air conditioners are closely related to customers' lives. There are higher requirements for air conditioners. On the one hand, the comfort must meet the requirements. On the other hand, the noise problem is not only satisfied with the size of the total noise, but also to ensure that the noise peaks in other frequency bands of the noise cannot be too large. , It is necessary to ensure that there are no other abnormal noises. The da da sound of the external ...
