Description

Unloading valve pipeline structure for window type air conditioner
Technical field
The present invention relates to the air-conditioning technique field, is a kind ofly can improve the air-conditioner heat exchanger effectiveness specifically, reduces the unloader volume, reduces the unloading valve pipeline structure for window type air conditioner that unloader price and vibration of compressor cause damage.
Background technology
As shown in Figure 1, for comfortable temperature environment is provided to the user, the air regulator utilization is with the compressor of the refrigerant boil down to HTHP gaseous coolant of low-temp low-pressure gaseous state; Warm high-pressure liquid refrigerant during the HTHP gaseous coolant changed into, the condenser that internal heat is discharged simultaneously; Middle temperature high-pressure liquid refrigerant in the condenser is changed into the expansion valve of low-temp low-pressure liquid refrigerants; Change the low-temp low-pressure liquid refrigerants gaseous coolant of low-temp low-pressure into, and absorb medium circulation pipeline A-B-C-D-A that the parts such as evaporimeter of surrounding environment heat constitute to indoor refrigeration, heat or to air dewetting.
Air regulator still divides to be arranged in one according to cooling (refrigeration)/heat release (heating) function setting and is divided into one-piece type and separation type.Integral air conditioner be cooling (refrigeration)/heat release (heating) function setting in a casing, on the wall in house, burrow or on window, install; Saperated air conditioner separately is arranged at indoor set and off-premises station to cooling (refrigeration)/heat release (heating) function.Saperated air conditioner is divided into cabinet type, wall-hanging, embedded etc. again according to set-up mode or position.
Be illustrated in figure 2 as the existing cold window air conditioner structure of one-piece type list, it is by the cabinet 11 that forms appearance; The chassis 0 of parts is installed; Be arranged at the indoor panel 16 of indoor, chassis part, indoor panel central authorities are formed with air inlet 8, and indoor gas outlet 15 is arranged above; The indoor panel inboard is disposed with evaporimeter 7; It divides into drip tray (not drawing); Indoor centrifugal fan 5; Room air guiding 14; The dividing plate 6 of indoor and outdoor part; Outdoor section has fan electromotor 4; Compressor 1; Outdoor aerofoil fan 3; Condenser 2; Outdoor panel with exhaust outlet 12 constitutes.
Its running process of refrigerastion is: compressor 1 and fan electromotor 4 runnings when inserting power supply, refrigerant in its medium circulation pipeline by compressor 1 compression after in the direction of arrows by condenser 2 heat releases of outdoor section, be back to compressor 1 again after evaporimeter 7 heat absorptions through expansion valve 9, indoor section again or gas-liquid separator 10 carries out reciprocation cycle; And along with the running of fan electromotor 4, indoor and outdoor fan 5,3 begins to rotate, room air enters air-conditioner by the indoor air inlet 8 of indoor panel 16 central authorities, and passes evaporimeter 7 in the direction of arrows and carry out flowing back to indoor again by room air guiding 14 indoor air outlets 15 of guiding into above the indoor panel after heat exchange becomes cold air; Outdoor air enters air-conditioner by the outdoor air inlet 13 of side, is discharged in outdoor by the outdoor gas outlet 12 of central authorities after outdoor fan 3, condenser 2 carry out heat exchange to be heating installation.
The medium circulation pipeline figure of existing window air conditioner includes in its outdoor section as shown in Figure 3: be arranged on the gas-liquid separator that compressor on the chassis and outlet are connected in the suction port of compressor; Inlet is connected in the condenser that compressor extrudes mouth with the refrigerant pipe; Be connected in the main capillary (expansion valve) of condensator outlet; Its indoor section is provided with the evaporimeter that is connected between main capillary outlet and gas-liquid separator inlet; In order to alleviate the load of compressor; load with a part of laying down compressor between the inlet of general outlet that also two ends behind a unloader and the bypass capillary polyphone is connected in compressor and evaporimeter; the protection compressor is not damaged when strong pressure; but this connection makes a part of refrigerant just directly not enter evaporimeter through condenser condenses; the result reduces evaporimeter heat exchange effect, causes thermal loss.The inlet of unloader is connected in outlet high temperature, the locations of high pressure of compressor in addition, and its structure and thickness requirement are improved, and causes that its cost is also high, volume also increases.Moreover the long-time running vibration of compressor can make the unloader and the bypass capillary that are connected in compressor cause fatigue damage again.
Summary of the invention
The present invention is for solving the problems referred to above that prior art exists, design also discloses a kind of unloading valve pipeline structure for window type air conditioner, its two ends reconfiguration after with the series connection of unloader and bypass capillary is between the inlet of the outlet of condenser and evaporimeter, avoided refrigerant just directly not enter in the evaporimeter through condenser condenses, thereby the problem of evaporimeter heat exchange effect decline and the fatigue damage suffering that vibration of compressor causes have been solved, in addition, because the unloader inlet has not been directly connected in compressor outlet, so refrigerant pressure reduces, make the unloader structure, thereby thickness requirement reduces to make the unloader volume to reduce, and price reduces, safety coefficient increases.
Technical scheme of the present invention includes: be arranged on the gas-liquid separator that compressor on the chassis of outdoor section and outlet are connected in the suction port of compressor; Inlet is connected in the condenser of compressor outlet with the refrigerant pipe; Be connected in the main capillary of condensator outlet, be arranged on the chassis of indoor section, be connected in evaporimeter between main capillary outlet and gas-liquid separator inlet with pipeline; Be characterised in that: going back cross-over connection between the outlet of its condenser and the inlet of evaporimeter has unloader and bypass series pipe capillaceous.Because unloader directly is not connected to compressor outlet, unloader is away from the refrigerant of compressor outlet high temperature, high pressure, and its tube wall can attenuate, and therefore spring can subtract carefully
Its unloader can be made of the valve body smaller and more exquisite than existing unloader, thin valve wall, thin spring.
In addition, its unloader and bypass capillary can be installed and be arranged at from compressor far, are subjected to the outdoor section or the indoor section of the less window air conditioner of its vibration effect.
Advantage and good effect: the present invention compared with prior art has the following advantages:
A. the two ends reconfiguration after the series connection of unloader of the present invention and bypass capillary is between the inlet of the outlet of condenser and evaporimeter, avoided a part to be compressed the HTHP refrigerant that by compressor and just directly entered evaporimeter, reduced the heat exchange efficiency of evaporimeter without condenser condenses step-down, cooling.
Two ends reconfiguration after B, unloader of the present invention and the series connection of bypass capillary is between the inlet of the outlet of condenser and evaporimeter, and is far away from compressor, the fatigue damage of having avoided vibration of compressor to cause.
Unloader directly is not connected to compressor outlet among C, the present invention, therefore unloader is away from the refrigerant of compressor outlet high temperature, high pressure, so the structure of unloader, thickness requirement reduce, the unloader volume is reduced, the fatigue damage that causes of machine vibration is also little by compression, and price reduces, safety coefficient improves.
