Abstract
A new type of throttling device for mechanical refrigeration, which comprises a compressor, a condenser, a throttle valve, a refrigerated medium pipe and a refrigerating medium circulation pipe, characterized in that a set of throttling device composed of a plurality of throttle valves connected in parallel is provided on the pipeline the leads the refrigerating medium of the condenser into an evaporator, and is connected, through a connecting pipe, with the inlet pipes that are evenly arranged on the evaporator; as needed by throttling pressure difference, the throttle valves can be of the same model or different models. The increased number of throttle valves facilitates controlling over the throttling pressure difference, and the throttling control by a plurality of throttle valves guarantees the same throttling pressure difference even when the refrigerating load is increased and the refrigerant flow capacity is enlarged, therefore the best refrigerating result can be obtained.
Description
One, technical field
The utility model relates to a kind of mechanical refrigeration novel throttling device in the refrigeration system.
Two, background technology
In refrigeration system, mechanical refrigeration is the most general a kind of mode at present, the emphatically big effect of performance in the construction of the international people's livelihood and enterprises and institutions, but also exist some problems aspect energy-conservation, especially science very not also on the throttling link.The inlet that refrigerant advances evaporimeter has only one, and the refrigerant of entering is not easy to disperse, and can not bring into play the effect of cold-producing medium well; The choke valve of its usefulness also has only one, and directly the temperature of evaporator refrigerant is advanced in influence; Under the constant situation of liquid supply rate, the pressure after the throttling is more little, and temperature drop is big more, and the temperature of advancing evaporimeter is low more, and refrigeration is good more.When cooled load increases, will open greatly by an only choke valve, the joint temperature of this moment significantly improves, and directly influences the cryogenic temperature of the cooled medium in the evaporimeter.
Three, summary of the invention
The purpose of this utility model provides a kind of mechanical refrigeration novel throttling device, solves the problem of the poor refrigerating efficiency of above-mentioned prior art existence.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of compressor, condenser, choke valve, cooled medium tube and refrigerant circulation pipe, it is characterized in that refrigerant at condenser advances on the pipeline of evaporimeter is provided with the throttling arrangement that a cover is made up of the choke valve of a plurality of parallel connections, with tube connector be distributed on evaporimeter upper inlet pipe and link to each other, choke valve can be made as the choke valve of same model or the choke valve of different model according to the needs of chock pressure difference.
Compared with the prior art the utility model has the following advantages:
1, increases the restriction that advances evaporimeter, the cold-producing medium after the throttling can be distributed in the evaporimeter, can give full play to the effect of cold-producing medium.
2, increased the choke valve number, be convenient to control chock pressure difference, increased cooling load, under the situation that the refrigerant flow increases,, obtained needed chock pressure difference in the same old way, obtained best refrigeration by a plurality of choke valve throttling controls.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
The cooled medium tube 5-evaporimeter of 1-compressor 2-condenser 3-choke valve 4-6-refrigerant circulation pipe among the figure
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is by compressor 1, condenser 2, choke valve 3, cooled medium tube 4, evaporimeter 5 and refrigerant circulation pipe 6 are formed, compressor 1 outlet links to each other with condenser 2 imports by the refrigerant circulation pipe, condenser 2 outlets link to each other with evaporimeter 5 imports by throttling arrangement, evaporator outlet links to each other with the import of compressor 1 by refrigerant circulation pipe 6, throttling arrangement is made up of the choke valve 3 of a plurality of parallel connections, with tube connector be distributed on evaporimeter upper inlet pipe and link to each other, choke valve can be made as the choke valve of same model or the choke valve of different model according to the needs of chock pressure difference, with convenient control amount of restriction and chock pressure difference, the raising refrigeration is a purpose.
As on the refrigerating plant on the triumph Dongying compressor station cryogenic technology, having carried out the transformation of throttling flow process, advance at condenser on the throttling flow process of evaporimeter and increased by two throttling imports, two choke valves have also been increased simultaneously, increase to three imports by an import of advancing evaporimeter originally, be distributed on base of evaporator, and the choke valve of same model has been installed in three imports, three choke valves are parallel to the feed tube of evaporimeter.Pressure 1.5MPa before the propane throttling, 32 ℃ of temperature, under the situation that flow equates, the pressure after the throttling is reduced to 0.4MPa by 0.9MPa, and temperature is reduced to 3 ℃ by 26 ℃, and the temperature difference increases to 29 ℃ by 6 ℃; Significantly improved the refrigeration of refrigerant to cooled medium.
