Abstract
The expansion valve mechanism for outdoor unit of air conditioner includes a total pipe communicated with the refrigerant outputs of the condensers via connecting pipes; and a bi-directional throttle valve with one end connected to the total pipe and the other end communicated with the refrigerant inlet of the indoor unit of air conditioner. The present invention has detachable bi-directional throttle valve for replacing capillary, and possesses the advantages of easy fitting to different kinds of indoor unit, simplified design, short development period, being suitable for large scale production of different types of air conditioner, and being favorable to standardization of air conditioner parts.
Description
Technical field
The present invention relates to a kind of expansion valve of air-conditioner outdoor unit.The expansion valve mechanism that particularly relates to a kind of air-conditioner outdoor unit of suitable different model indoor set.
Background technology
Generally speaking, the course of work of air-conditioner is as follows: compressor is with the refrigerant of the refrigerant boil down to high temp/high pressure state of gaseous state; The gaseous coolant of boil down to high temp/high pressure state is cooled in condenser; In expansion valve, again the refrigerant of cooling is converted into the refrigerant of low temperature/low-pressure state; In evaporimeter, by heat exchange, absorb evaporimeter heat on every side, thereby reduce the temperature of surrounding air.
Air-conditioner can be divided into: one constitutes the integral air conditioner on the window etc. of being arranged at of refrigeration and heat rejection function; Be arranged on the indoor indoor set that includes evaporimeter, be arranged on the outdoor Saperated air conditioner that includes the off-premises station of compressor and condenser.
Saperated air conditioner is specifically: be arranged on the heat of evaporation that evaporimeter in the indoor set utilizes refrigerant, the temperature of surrounding air is descended, make the temperature of the position periphery that is provided with indoor set be lower than the temperature at other position.Be arranged on compressor and condenser in the off-premises station, the gaseous coolant via evaporimeter is converted to the refrigerant of high temp/high pressure state after, the operation of freezing.In order to improve the cooling effectiveness of refrigerant, in a side of off-premises station cooling fan and the drive motors that drives the cooling fan rotation are installed, make the low relatively force air of outside temperature pass through condenser, thus the cooling refrigerant.
Compressor from off-premises station is the refrigerant of low-temperature/high-pressure state through the refrigerant that condenser flows out, and needs in expansion valve, the refrigerant that cools off is converted into the refrigerant of low temperature/low-pressure state after, flow into again in the evaporimeter of indoor set, carry out heat exchange.
As shown in Figure 1, common employed expansion valve all adopts capillary.This version, each refrigerant exit 2 all will be connected with capillary 3 on the condenser 1, and then is connected with pyrogenicity capillary 5 and check valve 6 by capillary dispenser 4.
So, in the prior art, the off-premises station of its each model all must use the capillary of length-specific, specific quantity and particular inside diameters come throttling-.But, when indoor set changes, need redesign length capillaceous, quantity and internal diameter, adapt to new indoor set.Like this, the construction cycle of new model machine will be long, can't adapt to the demand in market fast.
Summary of the invention
Technical problem to be solved by this invention is that a kind of expansion valve mechanism of air-conditioner outdoor unit of applicable different model indoor set is provided.
The technical solution adopted in the present invention is: a kind of expansion valve mechanism of air-conditioner outdoor unit, include house steward, and house steward is connected with each refrigerant exit on the condenser by first tube connector and is communicated with; Also be provided with bidirectional throttling valve, one end of described bidirectional throttling valve is connected with the refrigerant of indoor apparatus of air conditioner inlet and is communicated with, the other end of described bidirectional throttling valve is connected and is communicated with second tube connector with nut by the formed first screw thread adapter in its termination, and the other end of second tube connector is connected with house steward and is communicated with; Described bidirectional throttling valve is formed with the second screw thread adapter at an end that is connected with the refrigerant of indoor apparatus of air conditioner inlet, and bidirectional throttling valve is by second screw thread adapter and the nut, is connected with the refrigerant inlet of indoor apparatus of air conditioner and is communicated with.Described second tube connector and house steward are fixedly connected and are communicated with.
The present invention uses dismountable bidirectional throttling valve to replace capillary, has following advantage:
1. when indoor set changes, only need redesign bidirectional throttle valve module can adapt to new indoor set.
2. use bidirectional throttling valve to replace refrigeration, heat capillary, simplified design.
3. shortened the construction cycle.
4. the same capabilities different types of air conditioners can be used shared part to greatest extent, is more suitable for large-scale production.
5. progressively advance the air-conditioning part to standardization, the development of sharing aspect.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, describe the expansion valve mechanism of air-conditioner outdoor unit of the present invention in detail.
As shown in Figure 2, the expansion valve mechanism of air-conditioner outdoor unit includes house steward 7, and house steward 7 is connected with each refrigerant exit 2 on the condenser 1 by first tube connector 12 and is communicated with; Also be provided with the bidirectional throttling valve 11 that an end is connected with house steward 7, the other end of bidirectional throttling valve 11 is connected with the refrigerant of indoor apparatus of air conditioner inlet and is communicated with.
Described bidirectional throttling valve 11 is to be connected with second tube connector 8 with nut 10 and to be communicated with by the formed first screw thread adapter 9 in its termination, and second tube connector 8 is connected with house steward 7 and is communicated with.And second tube connector 8 and house steward 7 are fixedly connected and are communicated with.
The end that the refrigerant inlet of described bidirectional throttling valve 11 and indoor apparatus of air conditioner is connected is formed with the second screw thread adapter 13, and bidirectional throttling valve 11 is by second screw thread adapter 13 and the nut, is connected with the refrigerant inlet of indoor apparatus of air conditioner and is communicated with.
The present invention, each outlet of condenser all is connected with a house steward, form a total outlet, promptly, the tube connector that will be connected with house steward is as a total outlet, and expansion valve adopts bidirectional throttling valve to replace capillary, and is connected with the refrigerant inlet of tube connector that forms condenser refrigerant general export and indoor set respectively by dismountable combination.Under this version,, when only changing indoor set,, be replaced with get final product corresponding with indoor set as long as bidirectional throttling valve is pulled down when off-premises station need not changed.
