Abstract
The invention discloses a big supercooling degree machine room air conditioner. A condenser consists of two parallel condenser tubes; and a supercooler is positioned between the two parallel condensertubes of the condenser. The refrigeration cycle comprises that: a refrigerant is converted into high-temperature high-pressure gas by the compressor, enters the two parallel condenser tubes of the co ndenser to exchange heat with air and enters a high-pressure liquid reservoir; the refrigerant flowing out of the high-pressure liquid reservoir enters a supercooler for supercooling heat exchange andbecomes the refrigerant with a big supercooling degree; the refrigerant with the big supercooling degree is throttled by an expanding valve and enters an evaporator for heat exchange; and finally the refrigerant is returned to the compressor to complete the whole refrigeration cycle. Because the refrigerant is supercooled after the high-pressure liquid reservoir, the problem that the supercooling degree is lowered because the conventional refrigerant is supercooled and then enters the high-pressure liquid reservoir is effectively solved; and because of the big supercooling degree, the refrige rant does not bubble when passing the expanding valve, the operating stability and reliability of the expanding valve are improved, and the refrigerating capacity and the refrigerating energy efficiency of the system are also improved.
Description
Technical field:
The present invention relates to a kind of computer-room air conditioning system, is a kind of air conditioner in machine room of big supercooling degree specifically.
Background technology:
At present, the computer-room air conditioning system overwhelming majority does not have supercooling apparatus, and the small part system layout has subcooler, often owing to the position of subcooler, has influenced the cold effect of mistake of system's reality greatly yet.Can bring a series of problem like this, such as the expansion valve job insecurity, refrigeration efficiency is not higher than EER, and refrigerating capacity is not enough etc.These all influence the result of use of air conditioner in machine room to a certain extent.
Summary of the invention:
In order to overcome the expansion valve job insecurity that prior art exists, defective such as refrigeration efficiency is not higher than EER, and refrigerating capacity is not enough the invention provides a kind of air conditioner in machine room of big supercooling degree, and it can effectively increase system's degree of supercooling, improves the self-operating operating mode; Improve refrigerating capacity, improve system's refrigeration efficiency than (EER).
The air conditioner in machine room of big supercooling degree of the present invention comprises compressor, condenser, high pressure fluid reservoir, subcooler, expansion valve and evaporimeter etc.Condenser is made of two parallel condenser, and subcooler is positioned in the middle of two parallel condenser of condenser.Its kind of refrigeration cycle is as follows:
Become high temperature and high pressure gas behind the compressed machine of cold-producing medium (refrigeration working medium), enter in two parallel condenser of condenser and the air heat exchange, enter the high pressure fluid reservoir then, the cold-producing medium that comes out from the high pressure fluid reservoir carried out cold heat exchange by subcooler, become cold-producing medium with big supercooling degree, cold-producing medium process expansion valve throttling with big supercooling degree enters the evaporimeter heat exchange, and last cold-producing medium turns back in the compressor again, finishes whole kind of refrigeration cycle.Described big supercooling degree is meant that system can stablize and realizes effective cold excessively more than 8 ℃.
The present invention has following beneficial effect with respect to prior art:
1, cold-producing medium carried out coldly after the high pressure fluid reservoir, effectively solved traditional cold-producing medium and crossed and enter the high pressure reservoir again after cold, the problem that degree of supercooling reduces.
2, subcooler is positioned in the middle of two parallel pipelines of condenser, can effectively utilize the powerful air flow field at blower fan middle part, the actual cold effect excessively of increase system.
Cold-producing medium did not have the bubble existence when 3, big supercooling degree can be guaranteed by expansion valve, had strengthened the stability and the reliability of expansion valve work.
4, big supercooling degree has effectively improved the refrigerating capacity of system, and the refrigeration efficiency that has improved system is than (EER).
Description of drawings:
Fig. 1 is the computer-room air conditioning system principle schematic of big supercooling degree of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiment:
As shown in Figure 1, the big supercooling degree computer-room air conditioning system comprises compressor 1, condenser 3, high pressure fluid reservoir 8, subcooler 4, expansion valve 5 and evaporimeter 7 etc.Condenser is made of two parallel condenser, and subcooler is positioned in the middle of two parallel condenser of condenser.Two parallel condenser of compressor 1 and condenser 3 link to each other, the condenser pipe outlet is connected with high pressure fluid reservoir 8, be communicated with subcooler 4 behind the high pressure fluid reservoir, subcooler connects expansion valve 5, arrive evaporimeter 7 again, turn back to compressor 1 at last, evaporator fan 6 and condenser fan 2 are used for realizing cold-producing medium and air enhanced heat exchange.
During system works, become high temperature and high pressure gas behind the compressed machine 1 of cold-producing medium, gas enters in the condenser 3 along pipeline, under the powerful wind field of condenser fan 2, cold-producing medium and air heat exchange, temperature reduces, enter high pressure fluid reservoir 8 along pipeline subsequently, the cold-producing medium that comes out from high pressure fluid reservoir 8 is by being positioned at the subcooler 4 at condenser middle part, utilize the efficient wind field in middle part of condenser fan 2 to reach the cold excessively purpose of increase once more, the cold-producing medium with big supercooling degree comes throttling through expansion valve 5, because have than big supercooling degree, do not have bubble during through expansion valve and exist, make cold-producing medium when throttling, have more stability.Through the low-temp low-pressure liquid of expansion valve 5 evaporimeter 7 of flowing through, under the wind field effect of evaporator fan 6, absorb the heat in the machine room, reach the purpose of refrigeration, last cold-producing medium turns back in the compressor 1 again, finishes whole kind of refrigeration cycle.Ownership cool equipment connects by refrigerant tubing 9, and cold-producing medium working medium adopts R22, R134a or R410A etc.
Except being applicable to that computer and data processor room are with the unit type air conditioner, the present invention can be widely used in the air-cooled cold wind formula of other single cold types vapor-compression refrigerant cycle, satisfy the user to needs stable, efficient, energy-conservation refrigeration, be expected to produce the huge social benefit.
