Description

Aerocraft special air conditioner car
Technical field:
Give in the utility model and the airport and stop aircraft and send the air-conditioned coach of cold wind relevant.
Background technology:
The difference of aerocraft special air conditioner car unit and common air-conditioning unit: because aerocraft special air conditioner car is the whole fresh wind air-condition device, need external high temperature air (35 ℃～45 ℃) is once directly dropped to low-temperature condition (1 ℃～5 ℃), on the evaporator layout, existing product all adopts the mode of serial connection multi-stage evaporator, carries out big enthalpy difference with new air to external world and handles.Now simply be described below:
Single compressor single system multi-evaporator is arranged in juxtaposition
Refrigeration system adopts a high-power compressor, use one group of condenser and one group of multi-stage evaporator, distribute unitedly to evaporators at different levels through cooled refrigerant, evaporator sizes at different levels are identical, according to the refrigeration demand amount that requires dispensing equivalent of evaporator exchange heats at different levels in the runner.
When adopting this kind system, the compressor rating horsepower causes required starting power quite big greatly, and is bigger to driving engine or generating set power requirement, is unfavorable for the equipment economical operation; And when heat exchange amount changes in demand was big, compressor behavior changed greatly, can not guarantee that compressor works under the optimum operation performance curve.
Multi-compressor single system multi-evaporator is arranged in juxtaposition
Single refrigeration system that multi-compressor closes pipe adopts many baby compressors, and each compressor exhaust pipe is merged, and uses same group of condenser; Evaporator adopts one group of multi-stage evaporator, distributes unitedly to evaporators at different levels through cooled refrigerant, and evaporator sizes at different levels are identical, according to the refrigerant demand that requires dispensing equivalent of evaporator exchange heats at different levels in the runner.
When adopting multi-compressor to close pipe, can influence the compressor air-discharging amount and reduce because the difference of each compressor air-discharging pulse produces pressure interference from causing system's refrigerating capacity; Multi-compressor closes Guan Shixu extra compressor oil balanced system is set, because the difference of each compressor air-discharging amount can cause each compressor oil return inequality, makes part compressor operating temperature build-up, influences the life-span.
Multi-compressor multisystem multi-evaporator is arranged in juxtaposition
Dual system or multisystem unit adopt multiple compressors, each compressor set works alone, use separately condenser and evaporator respectively, for making the equipment integral counterweight even, each compressor set refrigerating capacity is identical, this evaporator heat exchange amount that just requires each subsystem to be equipped with is identical, and the heat transfer temperature difference that is distributed between evaporator surface temperature and the gas flow temperature in each stage of evaporator air flow passage differs greatly, and just requires each subsystem to be equipped with the different evaporator heat exchange core body of heat interchanging area.
The different big or small heat exchange core bodies of difference design according to heat exchanger heat transfer boundary conditions at different levels have dual mode: the one, and different heat exchange core bodies adopts same row several deeply on the evaporator runner, gradually the wind area of Kuo Daing; The weak point that adopts this kind mode to exist is that evaporators at different levels windward side wind speed differs greatly, and has increased windage because variable section forms local eddy currents; Another kind is that each core body adopts identical wind area on runner, the dark number of heat exchanger row that increases gradually.Make the flow of refrigerant resistance of part system bigger than normal like this, evaporator coefficient of heat transfer differences at different levels can not guarantee the actv. utilization of evaporators at different levels.
The content of utility model:
The purpose of this utility model provides a kind of simple in structure, easy to manufacture, be convenient to regulate, the heat exchange efficiency height, can guarantee the two effective distribution that are equal to the refrigeration system refrigerant, guarantee the actv. utilization of evaporators at different levels, satisfy the aerocraft special air conditioner joint that new to external world air carries out big enthalpy difference processing requirements.
The utility model is achieved in that
