The specific embodiment
Referring to accompanying drawing 1, Fig. 2, in outdoor heat exchanger of air conditioner 1 middle and lower part fluid reservoir 11 is set, fluid reservoir 11 tops are provided with tube connector 10, last tube connector 10 1 ends insert fluid reservoir 11 and extend to position, the 10mm left and right sides, fluid reservoir 11 bottom, the other end of last tube connector 10 is connected with the condenser pipe of outdoor heat exchanger 1, fluid reservoir 11 bottoms are provided with down tube connector 13, one end of following tube connector 13 inserts fluid reservoir 11 and extends to position, the 10mmm left and right sides, fluid reservoir 11 top, and the end is provided with the bending of 70 to 90 degree, the last tube connector 10 of bending direction in the fluid reservoir 11, and the port of export after the bending has gap about 10mm apart from fluid reservoir 11 inwalls, such design mainly consider the installation site abundant and when heating the vapour-liquid mixed state can get to fluid reservoir 11 internal faces, liquid along playing under the wall flow under the effect that vapour-liquid two phases separate.The other end of tube connector 13 is connected with the condenser pipe of outdoor heat exchanger 1, and the bottom condenser pipe of the condenser pipe on outdoor heat exchanger 1 top, fluid reservoir 11 and outdoor heat exchanger 1 constitutes the passage of cold-producing medium, and tube connector 10 and following tube connector 13 are copper pipe.
As shown in figures 1 and 3, behind the outdoor heat exchanger 1 process copper pipe shunt 3 cold-producing medium is divided into three the tunnel, and fully take into account the influence and the countercurrent flow of gravity, adopted the flow path designs that does not wait journey, gather and enter into fluid reservoir 11 through distributor 8, to refrigerant distribute and stores after again through the bottom outflow of a U type Guan Houcong outdoor heat exchanger 1.
Refrigeration and the specific implementation process that heats are as follows:
When air conditioner refrigerating moves, cold-producing medium is compressed into HTHP by compressor steam by blast pipe and cross valve after inlet chamber external heat exchanger 1, outdoor heat exchanger 1 adopts the biexhaust pipe fin heat exchanger, behind the cold-producing medium process copper pipe shunt 3, the refrigerant vapor of HTHP is divided into three tunnel inflow outdoor heat exchangers 1, first via cold-producing medium is through first by-pass tube, 4 back inlet chamber external heat exchangers 1, from interior row, set out on a journey and flow to interior row's top, and through first elbow 15 back, top then flow to the outside of outdoor heat exchanger 1, cold-producing medium changes downward outflow into, again through flowing into outdoor heat exchangers 1 from second by-pass tube 6 after the shunt that flows into first branched pipe, 5. the second road cold-producing mediums process copper pipe shunt 3 behind three elbows, inwardly flow at row's middle part from interior row's middle and upper part, downwards cold-producing medium through three cross-over connection elbows after, flow into middle part second elbow 16, behind second elbow 16, cold-producing medium is turned to by interior row and flows into the middle part that effluxes, turn to upwards and flow out, finally flow into second branched pipe 7; Flow into the bottom of outdoor heat exchangers 1 after the shunt of Third Road cold-producing medium process copper pipe shunt 3 from the 3rd by-pass tube 12, inwardly flow at row's middle part from the interior row bottom of outdoor heat exchanger 1, behind cross-over connection triple section arm 17, turn to by interior row and to efflux, flow out downwards from the middle part that effluxes, finally flow into the 3rd branched pipe 9; More than three road cold-producing mediums all flow to distributor 8, become one the tunnel through after the mixing of distributor 8, tube connector 10 backs flow into fluid reservoir 11 on the process, the cold-producing medium of this moment has become subcooled liquid, through flowing into fluid reservoir 11 inside behind the tube connector 10 on the copper pipe, after waiting to be full of fluid reservoir 11, flow into outdoor heat exchangers 1 from following tube connector 13, flow out downwards from the bottom that effluxes of outdoor heat exchanger 1, efflux tube connector 14 through the bottom of a U type Guan Houcong outdoor heat exchanger 1 and flow out, enter capillary-compensated then, by entering evaporimeter behind the triple valve, get back to the cross valve of off-premises station again, the back flows into the air entry of compressor, has finished a kind of refrigeration cycle process.
When the air-conditioning heating operation, cold-producing medium is compressed into HTHP by compressor steam by blast pipe and cross valve after heat exchanger in the inlet chamber, after the condensation through inlet chamber external heat exchanger 1 behind the capillary-compensated, the tube connector 14 that effluxes from the bottom of outdoor heat exchanger 1 enters, cold-producing medium upwards flows out from the bottom from the heat exchanger that effluxes, through behind the U type pipe under the copper pipe tube connector 13 flow into fluid reservoirs 11, behind tube connector 13 under the copper pipe, vapour-liquid two is to the cold-producing medium of attitude going out to fluid reservoir 11 inwalls at a high speed, cold-producing medium mixes in fluid reservoir 11 under action of centrifugal force and distributes, because gravity effect, refrigerant liquid is in fluid reservoir 11 bottom deposits, steam state is on fluid reservoir 11 tops, liquid cold-producing medium effluxes upwards along outdoor heat exchanger 1 once more after by tube connector on the copper pipe 10 and flows out, fluid reservoir 11 has just been finished the process of a full-liquid type distributor like this, be divided into three the road after cold-producing medium distributes through distributor 8 and flow to outdoor heat exchanger 1: the first via flows into from first branched pipe 5, effluxing the middle and upper part from heat exchanger flows out to top, through arranging in first elbow, the 15 back inflow heat exchangers, flow out downwards, finally flow into copper pipe shunt 3 from first by-pass tube 4; The second road cold-producing medium flows into from second branched pipe 7 and effluxes the heat exchanger middle and upper part, flows out to the middle and lower part, through arranging in second elbow, the 16 back inflow heat exchangers, upwards flows into copper pipe shunt 3 through second by-pass tube, 6 backs; The Third Road cold-producing medium effluxes heat exchanger from the 3rd branched pipe 9 and flows into from the bottom, flow out to the middle and upper part, and row finally flows into copper pipe shunt 3 through the 3rd by-pass tube 12 backs from flowing out down in the heat exchanger through turning to behind the triple section arm 17.Three road cold-producing mediums are delivery chamber's external heat exchanger 1 after 3 kinds of mixing of copper pipe shunt, enters the compressor air suction mouth by cross valve, has finished one and has heated cyclic process.Outdoor heat exchanger 1 inboard is the heat exchanger leeward side, and the outside is the heat exchanger windward side.
