Description
Technical field
The invention belongs to the air-conditioner technical field, be specifically related to a kind of air conditioner and processing method thereof of using parallel-flow heat exchanger, be used for domestic air conditioner, commercial air conditioner or other refrigeration plants.
Background technology
Parallel-flow heat exchanger is also referred to as micro-channel heat exchanger, has heat transfer efficiency height, compact conformation, low, in light weight, the low cost and other advantages of noise.Be taken as condenser and be widely used in air conditioning for automobiles, in recent years, also be used as the condenser of family expenses, especially commercial use air conditioner.
Parallel-flow heat exchanger adopts flat tube augmentation of heat transfer technology, is a kind of porous aluminum flat pipe heat exchanger, and its structure is to adopt louvered fin in air side, and refrigerant side adopts the multi-channel flat pipe of minor diameter, thereby the heat exchange of air side and refrigerant side is strengthened.Use in family expenses air-conditioner field; Help improving efficiency, reduce refrigerant charge and alleviate unit weight, reduce the air-conditioner cost; Compare with common copper pipe heat exchanger, make domestic air conditioner obtain bigger improvement at aspects such as performance, volume, weight, costs.
Owing in refrigerated air-conditioning system, the cold-producing medium that gets into evaporimeter is a gas-fluid two-phase mixture, is divided into usually in the multichannel entering evaporimeter absorbing heat, and liquid phase is evaporated to gas to realize the purpose of refrigeration.Can cold-producing medium two-phase fluid, particularly wherein liquid be assigned to uniformly and carry out heat exchange in each paths, are the keys of evaporator designs.Under the service condition of actual complex, if each flat heat exchanger tube separatory is uneven in the evaporimeter, can cause different tube refrigerant mass flow discrepancies even, the less evaporation very soon of flow in the pipe, the degree of superheat of pipeline outlet is higher; The too much evaporation of flow does not finish in the pipe, and it is little to cause exporting the degree of superheat, even contains liquid; Make all under two kinds of situation that flat heat exchanger tube heat exchange area is not in full use.In addition, because the volume that the gaseous refrigerant of the flat heat exchanger tube of entering accounts for is bigger, occupied most space and heat exchange area, had a strong impact on heat exchange efficiency, made evaporimeter have to volume is done greatly, cost improves.
In view of the foregoing, at present in the family expenses commercial use air conditioner, parallel-flow heat exchanger is only made condenser and is used on single-cooling air-conditioner, has limited it at the application development of commercial, domestic air conditioner with popularize.
Summary of the invention
The present invention provides a kind of concurrent flow air conditioner in order to overcome the deficiency that above prior art exists, and makes the concurrent flow technology can realize freezing and heating, and solves shunting inequality, problems such as heat exchange efficiency is low, volume is big, cost height.
Another object of the present invention is to provide a kind of processing method of concurrent flow air conditioner.
The object of the invention is realized through following technical scheme: a kind of concurrent flow air conditioner; It is characterized in that: comprise compressor, compressor return air pipe, cross valve, indoor set, capillary module, go up the collector tube upper pipes, go up collector tube, flat heat exchanger tube and following collector tube; On described in the depression angle collector tube, collector tube is crooked " L " shape of circular arc down, compressor, compressor return air pipe connect two connectors of cross valve respectively, indoor set, go up two other connector that collector tube first end connects cross valve respectively; Indoor set connects through capillary module goes up the collector tube upper pipes; Last collector tube upper pipes connects upward collector tube second end, and last collector tube inside is provided with at least one dividing plate, and the flat heat exchanger tube through a plurality of parallel arrangements is communicated with between the collector tube up and down; Each flat heat exchanger tube has fin; Following collector tube first end is provided with gas-liquid separator, and gas-liquid separator connects check valve, the be connected in parallel same connector of cross valve of check valve and last collector tube first end.
According to different use occasions, the said collector tube inside of going up is provided with a dividing plate, and the concurrent flow air conditioner is 2 flow processs.
According to different use occasions, the said collector tube inside of going up is provided with two dividing plates, and following collector tube inside is provided with a dividing plate, and the concurrent flow air conditioner is 4 flow processs.
