Particularly, described condenser inlet end is connected to the C pipe of cross valve; Evaporimeter is connected to described gas-liquid separator by the S pipe of cross valve.
On the other hand, the present invention is by the following technical solutions:
A kind of central air-conditioning, described central air-conditioning comprises above-mentioned idle call refrigerant and crosses air-cooled structure.
Idle call refrigerant of the present invention is crossed in air-cooled structure and is positioned at gas-liquid separator with being communicated with pipeline portions between condenser and indoor set, the low-pressure low-temperature refrigerant in gas-liquid separator is utilized to carry out cold treatment to the refrigerant liquid formed after condenser condenses, obtain the refrigerant liquid that temperature reduces further, only local directed complete set is carried out to the pipeline in existing apparatus and can realize cold object, apparatus structure is reasonable, cost is low, crosses cold effective.
Central air-conditioning of the present invention comprises above-mentioned idle call refrigerant and crosses air-cooled structure, cross cold after through laggard compared with long pipeline enter indoor set be the refrigerant liquid of real cryogenic high pressure.Refrigeration, the heating effect of central air-conditioning are better, and energy consumption is low, and operating cost is low, can cover larger space.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that in the preferred embodiment of the present invention one, idle call refrigerant crosses air-cooled structure.
Be labeled as in figure:
1, condenser; 2, gas-liquid separator; 3, indoor set; 4, compressor; 5, electric expansion valve; 11, pipeline.
Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Preferred embodiment one:
This preferred embodiment provides a kind of idle call refrigerant to cross air-cooled structure.As shown in Figure 1, this is crossed air-cooled structure and comprises condenser 1, gas-liquid separator 2, indoor set 3 and compressor 4, and wherein, gas-liquid separator 2 is connected with compressor 4.
Concrete, pipeline 11 one end is connected to condenser 1 port of export, and the other end is connected to the entrance point of indoor set 3, and pipeline 11 passes from the inside of gas-liquid separator 2 at least in part.An electric expansion valve 5 is arranged on the pipeline 11 between condenser 1 port of export and gas-liquid separator 2.
Evaporimeter is connected to gas-liquid separator 2 by the S pipe of cross valve, and the refrigerant of the gas-liquid mixture phase that evaporimeter is discharged is separated through gas-liquid separator 2; Be separated the gaseous coolant obtained and will be sent to compressor 4.So be full of the refrigerant of low-pressure low-temperature in gas-liquid separator 2.
The cold media gas of HTHP enters condenser 1 from the C pipe of cross valve, the liquid of warm high pressure in being formed after condensation; Refrigerant liquid is entered in gas-liquid separator 2 by pipeline 11 and carries out exchange heat, realizes cold object, the temperature of refrigerant liquid reduce further laggard enter the entrance point of indoor set 3.
In order to improve the excessively cold efficiency of refrigerant liquid and effect, the part of pipeline 11 in gas-liquid separator 2 takes the shape of the letter U structure.The pipeline 11 of U-shaped stretches into from the top of gas-liquid separator 2, and the bottom of pipeline 11 is positioned at the bottom of gas-liquid separator 2.
Preferably, helical form is formed on the bottom of pipeline 11, can increase and treat the RT of heat exchange cooling medium liquid body in gas-liquid separator 2, crosses cold more abundant.
In this preferred embodiment, idle call refrigerant is crossed air-cooled structure and is utilized existing gas-liquid separator 2 pairs of refrigerant liquid to carry out cold treatment, and increase actual heat exchange area, systematic function is good, and cost is low, and the volume of device does not increase.
Preferred embodiment two:
This preferred embodiment provides a kind of idle call refrigerant to cross air-cooled structure, and its structure is substantially identical with preferred embodiment one.This crosses in air-cooled structure, and one end of pipeline is connected to condensator outlet end, and the other end is connected to the entrance point of indoor set, and pipeline passes from the inside of gas-liquid separator at least in part.The refrigerant of the gas-liquid mixture phase that gas-liquid separator is discharged for separating of evaporimeter, and deliver to compressor by being separated the gaseous coolant obtained; The gaseous coolant refrigerant liquid that formation temperature reduces after condenser condenses, refrigerant liquid is entered in gas-liquid separator by pipeline and carries out exchange heat, the temperature of refrigerant liquid reduce further laggard enter the entrance point of indoor set.
Difference is: the port of export of condenser to indoor set entrance point between the device controlling refrigerant fluid flow can be set, also can not arrange; Even if arrange the device controlling refrigerant fluid flow be also not limited to electric expansion valve.
The concrete shape of pipeline is not limit, and can determine according to concrete user demand; The part of pipeline in gas-liquid separator can repeatedly bend or be wound around, and to increase the RT of refrigerant liquid, crosses cold more thorough, crosses cold effect stronger.
Preferred embodiment three:
This preferred embodiment provides a kind of central air-conditioning.The idle call refrigerant that this central air-conditioning comprises as described in preferred embodiment one or two crosses air-cooled structure.Evaporimeter is connected to the inlet tube of gas-liquid separator by the S pipe of cross valve, and the outlet of gas-liquid separator is connected to compressor; The C pipe of cross valve is connected to the arrival end of condenser.
The excessively cold treatment of process in gas-liquid separator, cooling medium liquid temperature is lower.Through laggard compared with long pipeline enter indoor set be the refrigerant liquid of real cryogenic high pressure, so the refrigeration of this central air-conditioning, heating effect are better, energy consumption is low, and operating cost is low, can cover larger space.
