Description
Technical field
The utility model relates to the refrigeration system technical field.
Background technology
Shown in Figure 1 is the existing refrigeration system that comprises off-premises station and indoor set, and its off-premises station A comprises compressor 1, condenser 2, capillary 3, connects the tube connector 5 of off-premises station A and indoor set B, and its indoor set B comprises evaporimeter 4.Air-conditioning is in when refrigeration, and compressor 1 compression refrigerant also enters it in the condenser 2.When refrigerant liquid stream ran into capillary 3, it had been limited, thereby caused the increase of refrigerant pressure in the condenser 2.When the high-pressure refrigerant that has been compressed flows out capillary 3 when tube connector 5 flows into low pressure, jumbo evaporimeter 2, the also evaporation of expanding of this refrigerant, thus cause that the temperature in the evaporimeter 2 descends.The refrigerant of this moment roughly is gaseous state, and it shifts to compressor 1 then, is compressed and repeats this circulation once more at this refrigerant.
The capillary 3 that existing refrigeration system is used generally has following two kinds of versions: first kind: the capillary that bore is identical.Second kind: CN1186936A (application number 97126253.5) discloses a kind of refrigeration system and capillary thereof.Its capillary 3 comprises the capillary of a first 31 and a second portion 32 at least, described first 31 has one first cross section and constitutes inlet capillaceous, described second portion 32 has one greater than second cross section of first cross section and constitute liquid outlet capillaceous, described inlet capillaceous links to each other with the liquid outlet of described condenser, and described liquid outlet capillaceous links to each other with the inlet of described evaporimeter.
First kind of capillary is installed between the inlet of the liquid outlet of condenser 2 and tube connector 5, and cold-producing medium is just directly at the inlet place expansion trigger noise of tube connector 5.
Second kind of capillary mainly designs for preventing that capillary from stopping up, and still there is the problem that makes a noise in it.Main cause is: a, two sections capillary are because changeover portion is few, and the refrigerant of high pressure can't expand continuously, even if the two intersegmental capillaries that seamlessly transit also can't the cancellation noise; Has only the noise that allows the refrigerant of high pressure when flowing out capillary outlet, be expanded continuously and to send when can cancellation refrigerant flowing through capillary.B, most of manufacturer are when manufacturing this capillary, employing forms capillary with the mode of first and second portion welding, be the capillary that first 31 and second portion 32 are welded together to form as shown in Figure 2, when first 31 adopts scolder 33 welding with second portion 32,32 of first 31 and second portions easily form space 3132, and capillary can make a noise because of the backflow that this space 3132 produces when work like this.Owing to adopt welding manner that first and second portion are coupled together,, easily produce the stifled phenomenon of weldering because the capillary caliber is very little.
When first kind of capillary and second kind of capillary are applied on the split-type air conditioner, because it can make a noise, so two kinds of capillaries all are to install between the inlet of the liquid outlet of condenser 2 and tube connector 5 and it is placed outdoor to reduce its interference to indoor people.Cold-producing medium just must play a role in evaporimeter 4 through the tube connector 5 of general long 3-5 rice like this, and after testing, the 20-30% of tube connector 5 meetings loss refrigerating capacity in conductive process has caused the unnecessary waste of the energy.
The utility model content
Technical problem to be solved in the utility model is to overcome the existing big deficiency of refrigeration system energy loss and a kind of little noise, energy-saving refrigeration system are provided.
Technology solution of the present utility model is as follows:
Little noise, energy-saving refrigeration system, its off-premises station comprise the tube connector of compressor, condenser, capillary, connection off-premises station and indoor set, and its indoor set comprises evaporimeter; Its design feature is:
Capillary has first, second portion and third part at least, and first, second portion and third part constitute this capillary;
The bore of second portion is greater than the bore of first, and the bore of third part is greater than the bore of second portion;
The segmental arc face that a mild transition is arranged between the inside pipe wall of first and second portion has the segmental arc face of a mild transition between the inside pipe wall of second portion and third part;
The length of the shared entire capillary of first is greater than 3/5;
This capillary processes for the overall time disjunctor or casting forms;
The liquid inlet of tube connector connects the liquid outlet of condenser, the liquid outlet that capillary is installed between the inlet of the liquid outlet of tube connector and evaporimeter and first capillaceous takes in succession.
The utility model can also take following technical measures to solve:
The length of described second portion is the 20-300 millimeter, and the length of third part is the 20-300 millimeter.
The length of described second portion is less than the length of third part.
Outstanding effect of the present utility model is: because tube connector connects the liquid outlet of compressor, capillary is installed between the inlet of the liquid outlet of tube connector and evaporimeter.The cold-producing medium that is compressed that comes out in the tube connector, rather than finished the gaseous mixture of refrigeration work in the prior art, thus the gaseous mixture that can loss do not freezed of tube connector is saved refrigerating capacity like this, has saved the energy.

The specific embodiment
See Fig. 3,4, little noise, energy-saving refrigeration system, its off-premises station A comprises compressor 11, condenser 12, capillary 13, connects the tube connector 15 of off-premises station A and indoor set B, and its indoor set B comprises evaporimeter 14;
Capillary 13 has first 101, second portion 102 and third part 103 at least, and first 101, second portion 102 and third part 103 constitute this capillary 13;
The bore of second portion 102 is greater than the bore of first 101, and the bore of third part 103 is greater than the bore of second portion 102;
The segmental arc face 104 that a mild transition is arranged between the inside pipe wall of first 101 and second portion 102 has the segmental arc face 105 of a mild transition between the inside pipe wall of second portion 102 and third part 103;
The length of first's 101 shared entire capillaries is greater than 3/5;
This capillary 13 prolongs or casts for the overall time disjunctor rolls and forms;
The inlet of tube connector 15 connects the liquid outlet of condenser 12, and capillary 13 is installed between the inlet of the liquid outlet of tube connector 15 and evaporimeter 14 and the first of capillary 13 takes over 15 liquid outlet in succession.
The length of second portion 102 is 50 millimeters, and the length of third part 103 is 100 millimeters.
Operation principle: the inlet of tube connector 15 connects the liquid outlet of condenser 12, and capillary 13 is installed between the inlet of the liquid outlet of tube connector 15 and evaporimeter 14.Because condenser is formed by the copper pipe coiling, tube connector 15 has become the part of condenser 12 in fact like this, and the pipe of condenser 12 is original just very long, increases a bit very little to the refrigeration loss, and be the gas that has freezed in the tube connector 5 in prior art, through outdoor too big to indoor refrigeration loss.The utility model needn't directly freeze in evaporimeter 14 through tube connector 15, so the utility model has been saved the loss of refrigerating capacity, energy-saving effect is obvious.Because the utility model capillary 13 particular structure, this capillary has three parts, the length of first is greater than 3/5, the length of second portion and third part must design shortly, therefore it is except that having anticlogging function, and its second portion and third part expand one by one to the cold-producing medium of high pressure can play the effect that abates the noise.As seen the noise that sends of this capillary is little, indoorly can not produce interference to indoor people so be installed in.
