Abstract
This invention discloses a kind of one drag more air condition machine. It includes one outdoor machine and many indoor machines. On the outdoor machine there sets the cold medium efferent duct and the cold medium input tube. On the indoor machines there set the cold medium efferent duct and the cold medium input tube. And every indoor machine's cold medium efferent duct connects with the outdoor machine's cold medium input tube. Between the stated indoor machines' cold medium input tube and the outdoor machine's entrance connection pipe there is a tube module. The one drag more air condition machine provided in this invention is to connect with a tube module between every indoor machine's cold medium input tube and the outdoor machine's entrance connection pipe. It uses the tube module's rapid switch to control indoor machine's cold medium supply. When some indoor machine has problem and needs repairing, it can stop this indoor machine's work and will not affect the other indoor machine's and the whole system's work. So it can reduce the repairing workload and the cost. And it will not appear the leak of cold medium and the polluted environment problems.
Description
Technical field
The present invention relates to a kind of air-conditioner, particularly relate to a kind of multi-split air conditioner.
Background technology
Air-conditioner is a kind of device that makes its inner refrigerant carry out the refrigeration of being made up of compression process, condensation process, expansion process and evaporation process or heat circulation.When air-conditioner carries out kind of refrigeration cycle, compressed machine compression and the refrigerant that becomes high-temperature high-pressure state can dispel the heat to the outside in condenser, and when flowing through expansion valve, significantly reduce its temperature and pressure, this low temperature, low pressure refrigerant can absorb heat when flowing through evaporimeter then, flow back in the compressor again at last.Wherein, compression process, condensation process and expansion process are to carry out in the off-premises station of air-conditioner, and evaporation process then is to carry out under the effect of blowing fan in indoor set and evaporimeter.It is then opposite with above-mentioned kind of refrigeration cycle process to heat circulation.Air-conditioner is divided into detachable air conditioner and window air conditioner usually, and detachable air conditioner then comprises the multi-split air conditioner that is made of an off-premises station and Duo Tai indoor set.Fig. 1 is the multi-split air conditioner structural representation of prior art.Fig. 2 is the refrigerant input pipe and the inlet tube connector connecting portion STRUCTURE DECOMPOSITION schematic diagram of the multi-split air conditioner indoor set among Fig. 1.As Fig. 1～shown in Figure 2, the multi-split air conditioner of this prior art mainly comprises an off-premises station 1 and Duo Tai off-premises station 2～5.Off-premises station 1 is provided with refrigerant efferent duct 6 and refrigerant input pipe 7, then is provided with refrigerant input pipe 8 and refrigerant efferent duct 9 on the indoor set 2～5; Wherein, the end of refrigerant input pipe 8 is formed with an enlarging 10 on the indoor set 2～5, and the body outside is with a nut 11, the front end of indoor set 2～5 upper inlet tube connectors 12 is connected with a nipple 13 simultaneously, and nut 11 is combined with nipple 13 just can interconnect refrigerant input pipe on the indoor set 2～5 8 and inlet tube connector 12.Liquid refrigerants from off-premises station 1 will offer every indoor set 2～5 by the refrigerant efferent duct 6 of off-premises station 1 and the refrigerant input pipe 8 of each indoor set 2～5.Enter the refrigerant of indoor set 2～5 will be respectively with each interior space in air carry out heat exchange, the refrigerant that becomes gaseous state through heat exchange will focus on the refrigerant input pipe 7 of off-premises station 1 through the refrigerant efferent duct 9 of indoor set 2～5 and flow back in the off-premises station 1.But there is following point in the multi-split air conditioner with said structure: if certain indoor set breaks down and need disassemble maintenance in the running of air-conditioner, at first must stop the operation of whole air-conditioner, reclaim refrigerant then.Need the pipeline in the system is vacuumized after waiting to keep in repair end, then could normally move, so not only waste time and energy, and influence the use of other indoor set, and also might cause a large amount of leakages of refrigerant and cause environmental pollution as misoperation.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of easy to maintenancely, thereby can save working time and reducing labor intensity, and can prevent that the multi-split air conditioner that leaks from appearring in refrigerant.
In order to achieve the above object, multi-split air conditioner provided by the invention comprises an off-premises station and Duo Tai off-premises station, and off-premises station is provided with refrigerant efferent duct and refrigerant input pipe, and indoor set is provided with refrigerant input pipe and refrigerant efferent duct; And the refrigerant efferent duct of every indoor set links to each other with the refrigerant input pipe of off-premises station simultaneously; Be connected with a pipe assembly between the refrigerant input pipe of described indoor set and the inlet tube connector of indoor set.
Described pipe assembly comprises expander, nut, switch, tube connector and nipple soon; Wherein, an end of expander is formed with an enlarging, and its nut that can be enclosed within its body outside with the nipple utilization of inlet tube connector front end on the indoor set links together; The other end of expander then links to each other successively with switch, tube connector and nipple soon, and nipple then can match with the nipple of the refrigerant input pipe outside that is enclosed within indoor set and will manage assembly and the refrigerant input pipe links together.
The nipple of the inlet tube connector front end of nipple on the described pipe assembly and indoor set is measure-alike.
The refrigerant input pipe of expander and nut and indoor set and nut is measure-alike on the described pipe assembly.
Multi-split air conditioner provided by the invention is to connect a pipe assembly between the refrigerant input pipe of every indoor set and indoor set inlet tube connector, utilize the switch soon of managing on the assembly to control the refrigerant supply of indoor set, so just can when breaking down and need repairing, certain indoor set only stop the operation of this indoor set, and can not influence the operation of other indoor set and whole system, thereby can reduce maintenance load and expense, and the problem of environmental pollution that coolant leakage can not occur and cause thus.
Description of drawings
Below in conjunction with the drawings and specific embodiments multi-split air conditioner provided by the invention is elaborated.The parts identical with prior art use identical symbol, and omit its explanation of carrying out.
