Abstract
The utility model discloses a kind of can the SPLIT AIR-CONDITIONING SYSTEM of convenient refrigerant feeding, comprising: the compositions such as the threeway (8) of outdoor heat exchanger (1), throttling arrangement (2), compressor (3), outdoor fan (4), indoor and outdoor machine connecting pipe (5), indoor fan (6), indoor heat exchanger (7), band needle valve.The mounting means of existing SPLIT AIR-CONDITIONING SYSTEM, be doomed its increase along with service time, intrasystem cold-producing medium will inevitably be revealed to air, makes to lack cold-producing medium in system, does not reach designing requirement, normally work for making it, needing to add cold-producing medium in split-type air conditioner, but mostly be skyscraper due to present urban architecture, is often outdoor overhead operation to air-conditioning refrigerant feeding, complicated operation is dangerous large.Can the SPLIT AIR-CONDITIONING SYSTEM of convenient refrigerant feeding, by arranging the threeway of band needle valve in indoor, the indoor refrigerant feeding of split-type air conditioner can be realized, avoid the outdoor overhead operation of air-conditioning refrigerant feeding, reduce the danger of refrigerant feeding.
Description
Technical field
The utility model relates to air-conditioning system, especially a kind of can the SPLIT AIR-CONDITIONING SYSTEM of convenient refrigerant feeding.
Background technology
Air-conditioning was once cited as one of greatest invention of mankind's twentieth century, it makes indoor air temperature, humidity, cleanliness factor, air velocity and air quality etc. reach certain requirement by artificial method, meet life, production requirement, improve labour health condition, bring comfortable living and working environment.
The mounting means of existing SPLIT AIR-CONDITIONING SYSTEM, be doomed its increase along with service time, intrasystem cold-producing medium will inevitably be revealed to air, makes to lack cold-producing medium in system, do not reach designing requirement, for making it normally work, need to split-type air conditioner refrigerant feeding, but mostly be skyscraper due to present urban architecture, often work high above the ground to air-conditioning refrigerant feeding, complicated operation, greatly dangerous, price is also expensive.If design a kind of can the SPLIT AIR-CONDITIONING SYSTEM of convenient refrigerant feeding, realize the convenient indoor refrigerant feeding of split-type air conditioner, avoid the work high above the ground of air-conditioning refrigerant feeding, reduce the danger of refrigerant feeding, will bring to the operation and maintenance of air-conditioning convenient.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned deficiency, there is provided a kind of can the SPLIT AIR-CONDITIONING SYSTEM of convenient refrigerant feeding, by the threeway of the band needle valve in indoor setting, the convenient indoor refrigerant feeding of split-type air conditioner can be realized, avoid the work high above the ground of air-conditioning refrigerant feeding, reduce the danger of refrigerant feeding.
To achieve these goals, the utility model is by the following technical solutions:
A kind of can the SPLIT AIR-CONDITIONING SYSTEM of convenient refrigerant feeding, comprise: the threeway (8) of outdoor heat exchanger (1), throttling arrangement (2), compressor (3), outdoor fan (4), indoor and outdoor machine connecting pipe (5), indoor fan (6), indoor heat exchanger (7), band needle valve, wherein: in the pipeline of SPLIT AIR-CONDITIONING SYSTEM along flow of refrigerant direction, after throttling arrangement, before suction side, be provided with the threeway of band needle valve;
The threeway (8) of described band needle valve, when air-conditioning system is normally run, needle-valve (8c) is in normally off, and the first port (8a) and the second port (8b) are in pass-through state;
The threeway (8) of described band needle valve, comprises but is not limited only to three interfaces;
Also four-way change-over valve can be provided with, with the object realizing air-conditioning system indoor set cooling in summer, winter heats in described system.
Owing to adopting technique scheme, the utility model has the following advantages and effect:
The utility model is little for existing SPLIT AIR-CONDITIONING SYSTEM change part, produce any impact to hardly existing production line and production process, the normal operation of air-conditioning system is not also had any impact, but can realize supplementing cold-producing medium easily in indoor when air-conditioning system lacks cold-producing medium, avoid the work high above the ground of existing split-type air conditioner refrigerant feeding, reduce the danger of refrigerant feeding, both convenient and swift, security improves again greatly.
Accompanying drawing explanation
Fig. 1 is SPLIT AIR-CONDITIONING SYSTEM figure of the present utility model;
Fig. 2 is the system schematic of SPLIT AIR-CONDITIONING SYSTEM of the present utility model when using as heat pump.
Detailed description of the invention
As shown in Figure 1, the utility model system constitutes outdoor machine part A by outdoor heat exchanger 1, throttling arrangement 2, compressor 3, outdoor fan 4, the threeway 8 of indoor and outdoor machine connecting pipe 5, indoor fan 6, indoor heat exchanger 7, band needle valve constitutes indoor set part B, air-conditioning system indoor and outdoor machine connecting pipe 5 in the past indoor section by welding mode and indoor heat exchanger form an entirety, its mode connect by silk at C place with off-premises station is connected, this connected mode is doomed cold-producing medium in detachable air conditioner running and is revealed in air and become a kind of inevitable, after detachable air conditioner uses a period of time, due to leakage of refrigerant, refrigerating capacity can be caused to decline, one of solution is exactly in system, supplement cold-producing medium by C, but because Modern City Building mostly is skyscraper, off-premises station is general higher on outdoor mounted height distance ground, the work of this supplementary cold-producing medium brings very large suffering and danger.
The utility model is by the pipeline before the laggard evaporimeter of throttling arrangement, increase the threeway 8 of a band needle-valve, threeway 8 comprises but is not limited only to three interfaces, first port 8a of threeway 8 is connected with SPLIT AIR-CONDITIONING SYSTEM pipeline with the second port 8b, needle-valve 8c is normally off, a kind of can the SPLIT AIR-CONDITIONING SYSTEM of convenient refrigerant feeding normally work time, its method of operation and existing conventional SPLIT AIR-CONDITIONING SYSTEM are without any difference, but when system shortage cold-producing medium needs supplementary, by being with the threeway 8 of needle valve, cold-producing medium can be supplemented easily in system by normally closed needle-valve 8c.Owing to being with after the threeway 8 of needle valve is arranged on throttling arrangement, before suction side, belong to system low-voltage side, therefore cold-producing medium can add in split-type air conditioner easily.
In addition, air-conditioning system also can be provided with four-way change-over valve.When SPLIT AIR-CONDITIONING SYSTEM is normally run, the device that can realize the cold-producing medium side connection valve or other refrigerant feeding that add refrigeration system indoor all belongs within this patent protection domain
Be more than the utility model case study on implementation embodiment, all corresponding modifications made according to feature listed by present patent application scope are changed, and are all contained within the scope of present patent application.
Understand in scope those skilled in the art, SPLIT AIR-CONDITIONING SYSTEM comprises single-cooling type SPLIT AIR-CONDITIONING SYSTEM and pump type heat SPLIT AIR-CONDITIONING SYSTEM; SPLIT AIR-CONDITIONING SYSTEM includes but not limited to wall-hanging and cabinet air conditioner, and all compressors or the main frame containing compressor are placed in outdoor, and another heat exchanger is placed in indoor (or in certain space) and all belongs to SPLIT AIR-CONDITIONING SYSTEM described herein.
