Problems solved by technology

[0005] In the cooling mode of the traditional refrigeration and air-conditioning system, it undertakes two functions of cooling and dehumidification at the same time. In order to achieve dehumidification, the evaporation temperature is blindly reduced, resulting in a decrease in system energy efficiency. Moreover, the change of the operating state of the air-conditioning system makes the compressor vibrate when it is running at low load. Large, high noise and other issues; reduced human comfort

Embodiment 1

[0026] Embodiment 1: A method for reducing vibration noise of a compressor.

[0027] A method for reducing the vibration noise of the compressor, through the pre-designed first cylinder 1 volume V1, the second cylinder 2 volume V2, the first cylinder exhaust hole area S1 (that is, the size of the exhaust hole) and the second cylinder exhaust The parameters of the hole area S2 (that is, the size of the vent hole), so that it satisfies , m represents the minimum proportional value, p represents the maximum proportional value, and n represents the proportional coefficient, so as to achieve the purpose of improving the torque fluctuation of the compressor, and then reduce the vibration and noise of the compressor.

Embodiment 2

[0028] Embodiment 2: a kind of partial structure of compressor, such as figure 1 shown.

[0029] A compressor, including a first cylinder 1 and a second cylinder 2, the volume of the first cylinder is V1, the area of ​​the exhaust hole of the first cylinder is S1 (that is, the size of the exhaust hole), and the volume of the second cylinder is is V2, the exhaust hole area of ​​the second cylinder is S2 (that is, the size of the exhaust hole), and the relevant parameters of the first cylinder 1 and the second cylinder 2 need to meet , m represents the minimum proportional value, p represents the maximum proportional value, and n represents the proportional coefficient. Designing the volume of the first cylinder V1, the volume of the second cylinder V2, the area of ​​the exhaust hole of the first cylinder S1 and the area of ​​the exhaust hole of the second cylinder S2 within a certain range can not only effectively improve the performance of the rotary compressor under differe...

Embodiment 3

[0032] Embodiment 3: a kind of compressor.

[0033] The difference from Embodiment 2 is that the targeted refrigerant is R22 or R290 refrigerant, and the parameters of m, p, and n are set as follows: , n takes 0.055-0.080.

Abstract

The invention provides a compressor, an air conditioner refrigeration system and an air conditioner. The compressor comprises a first cylinder and a second cylinder, wherein the volume of the first cylinder is V1, the area of an exhaust hole of the first cylinder is S1, the volume of the second cylinder is V2, and the area of an exhaust hole of the second cylinder is S2. The first cylinder and thesecond cylinder meet the formula shown as the description, specifically, m represents the minimum proportion value and is greater than 0.2 and smaller than 1.1; p represents the maximum proportion value and is greater than 1.4 and smaller than 3.0; and n represents the proportional coefficient and is greater than 0.02 and smaller than 0.140. According to the compressor, the torque fluctuation ofthe rotary compressor is effectively improved under different refrigerant conditions, the vibration of the rotary compressor can be effectively reduced, the noise is lowered, the cost is reduced, andthe human body comfort is improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor, an air-conditioning refrigeration system and an air conditioner. Background technique [0002] At present, many indoor heat exchangers of air conditioners are composed of two rows of heat exchangers. The heat exchange air flow passes through the two rows of heat exchangers successively. The air temperature of the heat exchanger is different. When the air passes through the heat exchanger on the air outlet side, the heat exchange temperature difference decreases, and the efficiency of the heat exchanger cannot be fully utilized. [0003] Air conditioning dehumidification is also a very important function of the air conditioner. In fact, the principle of dehumidification of the air conditioner is the same as that of refrigeration. It also relies on the operation of the entire refrigeration system, using the compressor to cool down, and the indoor unit fan to disc...
