Specific embodiment
In order to be more clearly understood that the above objects, features, and advantages of the utility model, with reference to the accompanying drawing and have
The utility model is further described in detail in body embodiment.It should be noted that in the absence of conflict, this Shen
The feature in embodiment and embodiment please can be combined with each other.
As shown in Fig. 2, the utility model provides a kind of air conditioner 1, including indoor unit 11, outdoor unit 12 and connecting tube
13, the outdoor unit 12 includes the compressor 122 and First Heat Exchanger 121 being connected, and the indoor unit 11 includes being connected
Restricting element 112 and the second heat exchanger 111, the connecting tube 13 include the first tube body 131 and the second tube body 132, described first
Tube body 131 connects with second tube body 132 to exchange heat；The First Heat Exchanger 121 by the first tube body 131 with it is described
Restricting element 112 is connected to, and second heat exchanger 111 is connected to by the second tube body 132 with the compressor 122.
Air conditioner 1 provided by the utility model, air conditioner 1 provided by the present application place restricting element 112 indoors,
First tube body 131 and the second tube body 132 are able to carry out heat exchange, therefore do not need to coat heat-insulated material in the outside of connecting tube 13
Material, can reduce cost, since a connecting tube 13 can be realized as First Heat Exchanger 121 and the heat exchange of restricting element 112, second
The connection of device 111 and compressor 122, therefore air-conditioning installation difficulty is reduced, beautify connecting tube 13；Refrigerant section can be increased simultaneously
Degree of supercooling and suction superheat before flowing, and then can reduce evaporating temperature, to improve the refrigeration or heating energy of air conditioner 1
Power improves air-conditioner efficiency.
It is at this time condenser in outdoor First Heat Exchanger 121 by taking the refrigeration of air conditioner 1 as an example, the second heat exchange indoors
Device 111 is evaporator, and the liquid refrigerants (temperature is about 80-90 °) for the high temperature and pressure that compressor 122 generates passes through compressor 122
Become the liquid refrigerants (temperature is about 40-50 °) of medium temperature high pressure and heat release, liquid refrigerants passes through on integrated union pipe 13 at this time
The first tube body 131 be connected to restricting element 112, the gaseous state for becoming low-temp low-pressure by the liquid refrigerants of restricting element 112 is cold
Matchmaker's (temperature is about 6-13 °) is simultaneously absorbed heat, and then the gaseous coolant of low-temp low-pressure passes through the second tube body on integrated union pipe 13
132 are connected to compressor 122, and the refrigerant in the first tube body 131 is higher than the refrigerant temperature in the second tube body 132, therefore in the two
The temperature of refrigerant reduces in the first tube body 131 during progress heat exchange, and the temperature of refrigerant increases in the second tube body 132；
It is got higher in this way into the refrigerant degree of supercooling of restricting element 112, after refrigerant degree of supercooling increase herein, evaporating temperature can be made to reduce,
To improve the refrigerating capacity of system, the degree of supercooling of refrigeration system is condensator outlet refrigerant (corresponding to pressure) saturation
The difference of temperature and condensator outlet refrigerant temperature, refrigerant saturation temperature is constant, into the temperature of 112 refrigerant of restricting element
It reduces, and then degree of supercooling is caused to increase.Split-type air conditioner connects inside and outside machine using two long connecting tubes 13 of different sizes, passes
Defeated refrigerant.But evaporating temperature reduction can be such that the degree of superheat of evaporator outlet refrigerant reduces, so that 122 air-breathing parameter of compressor becomes
Difference, is unfavorable for system performance, allows refrigerant to flow through heat exchange type connecting tube 13 at this time and absorbs heat, that is, in the second tube body 132
Temperature increases after refrigerant heat exchange, compensates 122 air-breathing parameter of compressor, promotes suction superheat (suction temperature is 8-15 DEG C),
And then the refrigerating capacity of air conditioner 1 is improved, promote the efficiency of air conditioner 1.It is opposite when heating.13 structure of connecting tube and system
The performance of air-conditioning is improved on the whole.
First Heat Exchanger 121 is evaporator under heating mode, and the second heat exchanger 111 is condenser, the course of work and work
It is identical as refrigeration mode to make principle, only in cooling mode, indoor second heat exchanger 111 is evaporator, outdoor the
One heat exchanger 121 is condenser；And indoor second heat exchanger 111 is condenser in a heating mode, the first outdoor heat exchange
Device 121 is evaporator, therefore details are not described herein for its course of work.
The degree of supercooling of refrigeration system is condensator outlet refrigerant (corresponding to pressure) saturation temperature and condensator outlet
The difference of refrigerant temperature.Degree of supercooling increase will improve the refrigerating capacity of system.Since condensator outlet is to intercapillary
Connecting tube 13 is there are on-way resistance, local resistance and because gravity losses caused by height, and connecting tube 13 and environment exist
Heat exchange, can all influence the variation of degree of supercooling.To guarantee capillary inlet liquid condition to postpone shwoot, system should maintain one
Fixed degree of supercooling.The degree of superheat is evaporator outlet refrigerant temperature and evaporator outlet refrigerant (corresponding to pressure) saturation temperature
The difference of degree.For the safe operation for guaranteeing compressor 122, system is required to certain degree of superheat, and the increase of the degree of superheat will lead to
Effective disengagement area of evaporator reduces, the reduction of refrigerating capacity and Energy Efficiency Ratio, and the degree of superheat is too small or evaporator outlet is gas-liquid two
When phase shape, Wet Compression is not only resulted in, also resulting in the reduction of 122 gas transmission coefficient of compressor, refrigerating capacity and Energy Efficiency Ratio reduces.
One embodiment according to the present utility model, as shown in figure 3, first tube body 131 and second tube body
132, mutual spiral winding, the contact area between the first tube body 131 and the second tube body 132 increases, and the first heat exchanger tube can be improved
And the second heat exchange efficiency between heat exchanger tube, further increase the performance of air-conditioning；Specifically, as shown in figure 3, first tube body
131 have opposite first end and second end, and the first end is connected to the First Heat Exchanger 121, the second end and institute
State the connection of restricting element 112；Second tube body 132 has opposite third end and the 4th end, the third end and described the
The connection of two heat exchangers 111, the 4th end is connected to the compressor 122.
According to the present embodiment example, as shown in figure 3, the connecting tube 13 includes first tube body 131 and one
A second tube body 132, first tube body 131 and a mutual spiral winding of second tube body 132.
