Description
Technical field
The utility model, which belongs to, determines frequency（Constant speed）Field of air conditioning, and in particular to one kind is made an uproar for eliminating fixed frequency air conditioner two phase flow
The silencing means of sound.
Background technology
Throttling is that compression-type refrigeration circulates one of four indispensable main process in air-conditioning, when refrigerant passes through a section
When flowing the aperture of device, a part of static pressure is transformed into dynamic pressure, and flow velocity increased dramatically, referred to as turbulent flow, and fluid is disturbed,
Frictional resistance increase, static pressure declines, and fluid is reached the purpose of reduction regulation flow.
Existing flow controller is divided into two kinds of situations, and the first situation is to arrange flow controller located at outdoor, close condenser, its
Noise influences smaller with respect to indoor occupant, but flow controller result in the reduction of air-conditioning efficiency located at outdoor；Second of situation be by
Flow controller is located at indoor, close evaporator arrangement, and its air-conditioner efficiency is higher compared to being located outside, but when compressor stops shutdown
Its noise influences larger to indoor occupant, when especially in the dead of night, if air-conditioning is produced in compressor stops stopping process
The two phase flow noise of " drone drone " will bring serious puzzlement.Frequency is determined with traditional（Constant speed）Exemplified by air-conditioning, air-conditioning
In the course of the work, compressor can automatic start-stop by phased manner, and when two will be produced in the 12~18s of compressor after a shutdown
Mutually stream noise, and continue about 12s or so time, because, the flow controller two ends of air-conditioning are high and low pressure side respectively, high
Pressure side discharges pressure, the natural evaporation in evaporator, as about 12s after compressor shutdown, because compressor is high to low-pressure end
Pressure does not continue to keep, i.e. compressor does not continue to pump out refrigerant, but the liquid refrigeration between condenser and flow controller
Agent still discharges constantly to low-pressure end, so, will go out in the conveyance conduit between condenser and flow controller
The existing space without liquid refrigerant, now, the refrigerant of liquid will gasify, and gas-liquid two-phase, gaseous system are become by pure liquid
The tube wall of cryogen and the refrigerant mixing vibration shock delivery pipeline of liquid, this just generates two phase flow noise.Equally, compression is worked as
Two phase flow noise can be also produced in 12~18s after machine startup, because in 0~12s, refrigerant is converted into by pure gaseous state
The tube wall of the refrigerant mixing vibration shock delivery pipeline of gas-liquid two-phase, gaseous refrigerant and liquid, this just generates two-phase
Flow noise.As can be seen here, in the presence of refrigerant is in air-conditioning with the hybrid mode of gaseous state and liquid, two phase flow will be produced and made an uproar
Sound.
Therefore, the two-phase flow noise produced when how to eliminate start/stop of compressor, frequency sky is determined so as to provide one kind and be used to eliminate
The silencing means of two phase flow noise is adjusted, gives people to create a comfortable environment of peace and quiet, is the class to be studied of the utility model
Topic.
