This tonifying Qi pipeline comprises the first paragraph tonifying Qi pipeline, the second heat exchanging medium passage that are connected between one end of the second heat exchanging medium passage and the gas supplementing opening 1c of compressor 1, by threeway 9, is connected in the second segment tonifying Qi pipeline between heat exchanger 10 first interfaces in the second heat exchanging medium passage other end and car, and described expansion valve 7, block valve 8 are arranged between second segment tonifying Qi pipeline.On described first paragraph tonifying Qi pipeline, be provided with check valve 13.Duct length between described check valve 13 and compressor 1 gas supplementing opening 1c is less than 500mm.
Described heat pump type air conditioning system also comprises side heat exchanger 2, this side heat exchanger 2 is arranged in the interior air distribution system 20 of car, in this air distribution system 20, be provided with the changes in temperature air door 16 of changes in temperature state in adjustable car, this changes in temperature air door 16 can block completely, partial occlusion or do not block described side heat exchanger 2, and described side heat exchanger 2 will be communicated with the exhaust outlet 1a of compressor 1 between compressor 1 and cross valve 3 with the air inlet 3a of cross valve 3.
The operation principle of this heat pump type air conditioning system is:
1. refrigeration mode: changes in temperature air door 16 blocks side heat exchanger 2 completely in 16a position, after the gas that cold-producing medium is compressed into HTHP through compressor 1, from the exhaust outlet 1a of compressor 1, flow out, then from 2a interface inflow side heat exchanger 2, from 2b interface, flow out to the air inlet 3a cross valve 3 again, the commutation of four interfaces of this cross valve 3 is by solenoid control, and when refrigeration mode, magnetic valve is in off-state, cross valve 3 now refrigeration stream is communicated with air inlet 3a to mouth 3b, gas returning port 3d flows to a mouthful 3c and is communicated with heating, cold-producing medium flow into car external heat exchanger 4 and dispels the heat through 4a interface to mouth 3b from the refrigeration stream of cross valve 3, cold-producing medium after heat radiation flows out and enters from the 5a interface of two-way heating power expansion valve 5 from 4b interface, in two-way heating power expansion valve 5, carry out step-down throttling, refrigerant cools atomization, the cold-producing medium flowing out from 5b interface enters into the first heat exchanging medium passage of Intermediate Heat Exchanger 6, from 6b interface, entering 6a interface flows out, and now, block valve in tonifying Qi pipeline is in closed condition, then through threeway 9 cold-producing mediums, from 10a interface, flow in car heat exchanger 10, by regulating the position of the internal-external cycle throttle 15 in air distribution system 20, in air blast 14 inhalation vehicles, the outer fresh air of hot-air or car is blown into cold wind in air distribution system 20 through the surface of heat exchanger 10 in car, by adjusting, blow face air door 17, blow pin air door 19 and defroster door 18 positions enter in car cold wind.Cold-producing medium is the rear temperature rising of heat absorption in heat exchanger 10 in car, then from heating of cross valve 3, flows to mouthful 3c and flows into, then be back in compressor 1 from gas returning port 3d outflow air entry 1b from compressor 1 after gas-liquid separator 12.
2. dehumidifying-heating mode: when car internal-external temperature difference larger, and humidity when larger in car, in car, moisture can condense in the sight line that affects driver on automotive window, so current electric motor car is adjusted to refrigeration mode by air-conditioning system exactly when dehumidifying demist, the outer temperature-difference of vehicle interior temperature and car is dwindled, avoid hydrogenesis.But the cold of refrigeration mode can cause discomfort to people, and air-conditioning system of the present utility model has dehumidifying-heating mode.This pattern is identical with the refrigerant flow direction of refrigeration mode, just changes in temperature air door 16 is adjusted in to the position between 16a position and 16b position, like this, the cold wind that high-temperature high-pressure refrigerant in side heat exchanger 2 can be blown out by air blast 14 is together brought in car, make leaving air temp suitable, reaching dehumidifying except in fog effect, occupant's comfort improves.
3. the first heating mode: this heat pump type air conditioning system will be enabled this pattern when environment temperature is greater than 0 degree Celsius, this heating mode is contrary with flow direction flow direction from cross valve 3 flows out of refrigeration mode.Cold-producing medium still flows out from the exhaust outlet 1a of compressor 1, after side heat exchanger 2, from air inlet 3a, enter cross valve 3, and now cross valve 3 commutations, refrigeration stream is communicated with gas returning port 3d to mouth 3b, and heat, flow to a mouthful 3c and is communicated with air inlet 3a, like this, cold-producing medium is from heating the 10b interface inflow flowing to mouthful 3c outflow from heat exchanger 10 in car, now heat exchanger 10 will absorb the interior cold air of car by air blast 14 in car, and hot-air is blown into and in car, reaches heating effect; And cold-producing medium flows out from 10a interface after heat exchanger in car 10, now, block valve is closed, tonifying Qi pipeline is closed, cold-producing medium flows into from the 6a interface of Intermediate Heat Exchanger 6,6b interface flows out, then in 5b interface enters into two-way heating power expansion valve 5, in this two-way heating power expansion valve 5, comply with and carry out step-down throttling, then cold-producing medium enters into car external heat exchanger 4 by 4b interface and again carries out from refrigeration stream, to mouth 3b, flowing into cross valve 3 after heat exchange with car outer air, and then flow in compressor 1 through gas returning port 3d, gas-liquid separator 12.
4. the second heating mode; When environment temperature is less than 0 degree Celsius, this heat pump type air conditioning system will be enabled this pattern, and this second heating mode and the first heating mode are basic identical, and just, the block valve on tonifying Qi pipeline is opened, and this block valve is magnetic valve.Block valve is opened, a cold-producing medium part continues operation according to the flow direction of the first heating mode so, another part flow in expansion valve 7 after threeway 9, under the step-down throttling atomization of expansion valve 7, become the cold-producing medium that temperature is lower, then flow into the second heat exchanging medium passage, wherein 6c interface and 6d interface are as two ports of the second heat exchanging medium passage, now cold-producing medium enters in the second heat exchanging medium passage of Intermediate Heat Exchanger 6 from 6c interface, the first heat exchanging medium passage inner refrigerant is further passed to the second heat exchanging medium passage inner refrigerant by tube wall heat, after the second heat exchanging medium passage inner refrigerant gasification, from 6d interface, flow out, through entering check valve 13, flow in the gas supplementing opening 1c of compressor 1, the next one circulation that the refrigerant mixed that enters the air entry 1b of compressor 1 with another road enters compressor 1, mainly to increase the refrigerant mass fluxes that sucks compressor 1, improve the Energy Efficiency Ratio of air-conditioning system.By the high temperature refrigerant in the first heat exchanging medium passage, by tube wall, give the refrigerant loses heat in the second heat exchanging medium passage like this, make the cold-producing medium in the second heat exchanging medium passage be gasificated into rapidly gaseous state, high temperature refrigerant in the first heat exchanging medium passage has also obtained being further cooled to subcooled liquid by the cold-producing medium in the second heat exchanging medium passage simultaneously, energy has obtained effectively utilizing, thereby the Energy Efficiency Ratio that improves air-conditioning system, now changes in temperature air door 16 can be in 16a and 16b optional position.
