Technical Field

The invention relates to the technical field of compressors, in particular to a compressor, an air conditioner refrigerating system and an air conditioner.

Background

At present, many indoor heat exchangers of air conditioners are composed of two rows of heat exchangers, heat exchange air flows successively pass through the two rows of heat exchangers, and the temperature of the air changes after the air passes through the heat exchanger on the air inlet side, so that the air temperature of the air passing through the two rows of heat exchangers is different, the heat exchange temperature difference is reduced when the air passes through the heat exchanger on the air outlet side, and the efficiency of the heat exchangers cannot be fully exerted.

Air conditioning dehumidification is also an important functional role of air conditioning. The principle of air conditioning dehumidification is the same as refrigeration, the whole refrigeration system is used for refrigeration, a compressor is used for refrigeration, and water in a room is discharged to the outside by an indoor unit fan. The independent dehumidification mode is known to those skilled in the art as the constant temperature air conditioning dehumidification principle, and its basic principle is to reheat the air cooled by the evaporator to the original temperature and then send it into the room, so that the indoor environment is kept relatively constant in the case of a decrease in humidity.

Cooling mode this is the mode that any air conditioner has, and is the most basic function of air conditioner. The refrigerated process of air conditioner must be accompanied with the dehumidification, and the humid air temperature can descend by a wide margin after passing through the air conditioner evaporimeter, and air humidity is in a supersaturated state, and unnecessary steam is appeared with the form of comdenstion water, condenses on the fin of evaporimeter, also is "condensation", waits until the refrigeration mode reaches certain equilibrium state, and air humidity has also fallen certain level.

In a refrigeration mode of a traditional refrigeration air-conditioning system, two functions of refrigeration and dehumidification are simultaneously undertaken, in order to realize dehumidification, the evaporation temperature is reduced once, so that the energy efficiency of the system is reduced, and the problems of large vibration, high noise and the like are caused when a compressor runs at low load due to the change of the running state of the air-conditioning system; the human body comfort is reduced.

Disclosure of Invention

Aiming at the defects of the prior art, the low-vibration and low-noise compressor of the cooling and heating type air conditioning system suitable for the double-evaporator single condenser or the double-evaporator double-condenser structure effectively improves the torque fluctuation of the rotary compressor under different refrigerant conditions, and can also effectively reduce the vibration of the rotary compressor, reduce the noise and reduce the increase of the cost.

In order to achieve the purpose, the invention adopts the following technical scheme:

a method for reducing vibration noise of compressor is to design cylinder volume and exhaust hole area in advance to improve moment fluctuation of compressor and reduce vibration and noise of compressor. The normal exhaust is discharged by the pump body, and its high-pressure gas axial passes through electric motor rotor, accomplishes the exhaust by the gas vent of upper cover subassembly, and the air current can produce the air current disturbance through electric motor rotor's clearance for the air gap between motor and the rotor increases the resistance, disturbs its moment fluctuation, increases the gas vent and has reduced the air current disturbance of discharge pressure to electric motor rotor, thereby reaches the undulant mesh of improvement rotary compressor moment, and then effectively reduces rotary compressor's vibration, noise abatement.

Further, the cylinders include a first cylinder and a second cylinder, and the torque fluctuation of the compressor is improved by adjusting the first cylinder volume V1, the second cylinder volume V2, the first cylinder vent area S1 and the second cylinder vent area S2. And the exhaust port is increased, so that the air flow interference of the exhaust pressure on the motor rotor is reduced, and the torque fluctuation of the rotary compressor is improved.

The parameter ranges of the first cylinder volume, the second cylinder volume, the first cylinder exhaust hole area and the second cylinder exhaust hole area are restrained through the formulas, the best improvement purpose is favorably achieved, the value ranges of m, p and n can be adjusted adaptively according to the conditions of different refrigerants, and the optimal processing effect is achieved.

Preferably, the ratio V1/V2 of the first cylinder volume V1 and the second cylinder volume V2 ranges from 0.4 to 1.0, and the ratio V1/V2 is limited to further ensure that the torque fluctuation of the compressor is not too large, so that the effect of reducing the vibration and the noise of the compressor is achieved.

An air-conditioning refrigeration system comprises the compressor, an evaporator and a condenser, wherein the evaporator is connected with the condenser through the compressor. The compressor solves the problem that the energy consumption of the system is reduced because the evaporation temperature is reduced for realizing the dehumidification function of the air-conditioning refrigeration system, improves the operation efficiency of the air-conditioning refrigeration system and avoids the waste of energy.

Further, the evaporator comprises a first evaporator and a second evaporator, the first evaporator is connected with the condenser through a first exhaust channel, and the second evaporator is connected with the condenser through a second exhaust channel. Under the condition that the air-conditioning refrigeration system does not need high efficiency, the structure of adopting a single condenser is beneficial to saving energy.

Further, the compressor comprises an air suction liquid distributor, and the air suction liquid distributor is connected with the evaporator through a pipeline. The suction liquid distributor is a container which temporarily holds the last refrigerant of the evaporator which is not completely changed into gas; the main functions are liquid storage and liquid impact caused by liquid refrigerant entering the cylinder.
