Abstract

The present invention relates to a high wind pressure air conditioner of a two-stage cooling type, which has the structure that a first loop is orderly provided with a compressor, a condenser, a filtration drier, an expansion valve and a first cooler; both ends of a second loop are respectively arranged in front of the expansion valve of the first loop and behind the first cooler in a connection mode, the second loop is orderly provided with an expansion valve and a second cooler, wherein the second cooler is covered with an outer cover of which both ends are provided with openings, one side of the outer cover facing the first cooler is connected with a high pressure blower, and the other side of the outer cover is connected with an air pipe. After the air at normal temperature is cooled and dehumidified in the first cooler, the air is led into the second cooler by the high pressure blower; cold air can be conveyed for a long distance without temperature rise for the cold air.

Description

The high wind pressure air conditioner of two-part cooling

[technical field]

The present invention relates to a kind of air conditioner, particularly a kind of high wind pressure air conditioner of two-part cooling.

[background technology]

No matter be the factory building or the tradition processing factory building of automated production at present, many full cold air factory buildings that moved towards central air-conditioning, wherein when calculating the freezing tonnage of central air conditioning, must be all considerations in the lump such as the thermic load of the caloric value of the caloric value of the thermic load of building, production equipment, lighting apparatus, fresh air and staff's thermic loads, the total heat duties that all factors are added up is the equipment standard of air-conditioning; Traditional air conditioner is as shown in Figure 1, it is to have compressor 10, condenser 11, filtering drying machine 12, expansion valve 13 and cooler 14 in regular turn, and all form the loop of a sealing therebetween with the pipeline connection, compressor 10 passes through coolant feed after condenser 11, filtering drying machine 12 and the expansion valve 13, heat around cooling agent meeting rapid expansion and a large amount of absorber coolers 14, pressure fan 15 can drive air and flow through cooler 14 this moment, and made cooler 14 absorb the heat of air and form cold air.

The freezing tonnage that why calculates air conditioner must have so many-sided consideration, its reason is to be that the space in the factory building is big, and the staff is few and be scattered in each different place separately, and traditional cooler freezes thereon for avoiding condensate water, and make it lose cooling effect, so be to be open condensate water back outflow naturally of condensing that is beneficial to around the cooler, therefore the airduct bore at relative pressure fan place must be bigger, the airduct bore greatly then makes the wind speed of cold air slow down, moreover traditional pressure fan wind speed is all below 2500fpm (being about 8200m/s), so the distance that its cold air of traditional air conditioner can be carried is quite limited, traditional structure is if replace the pressure fan of general wind speed with high pressure blower, with increase that cold air carries apart from the time, because be at a high speed, high pressure, air when the high pressure blower because the relation of friction, make the temperature of high pressure blower outlet to rise about about 8 ℃ than inlet temperature, illustrate: when the normal temperature air temperature of air conditioner porch is 27 ℃, and by the cold air temperature after the cooler cooling is 15 ℃, then make 8 ℃ of cold air temperature recoveries again via high pressure blower again, so the temperature of really experiencing in the factory building is 23 ℃, such air conditioner can not be called as air-cooling system, so also be a cool breeze equipment at most.

[summary of the invention]

The objective of the invention is to: a kind of high wind pressure air conditioner of two-part cooling is provided, can guarantees that cold air temperature can not go up in long distance conveying cold air in course of conveying.

Technical program of the present invention lies in: the high wind pressure air conditioner that a kind of two-part cooling is provided, its first loop has compressor in regular turn, condenser, filtering drying machine, the expansion valve and first cooler, and all form a loop therebetween with the pipeline connection, it is characterized in that: second loop is by external again second pipeline of the pipeline before the expansion valve in first loop, and the second pipeline other end is connected on the pipeline behind first cooler and forms second loop, be provided with the expansion valve and second cooler on second loop in regular turn, second cooler is provided with the outer cover that two ends form opening, outer cover is and one can drives the air outlet that air flows through the high pressure blower of first cooler and second cooler in regular turn and join that towards a side of first cooler opposite side then can be connected with more small-bore airduct.

The high wind pressure air conditioner of two-part cooling of the present invention has following characteristics:

1. can grow distance and carry cold air: because the outer cover at the present invention second cooler place and the design of small-bore airduct, be that the speed that can make cold air carry speeds, be beneficial to long distance and carry cold air, be that the cold air air outlet can be set at the fixed position at staff place in the factory building so, make any position in the factory building all can experience equal comfortable working environment.

2. cold air temperature does not go up because of course of conveying: because second cooler of the present invention design and two-part refrigerating function make cold air because of the friction of high pressure blower so the temperature that improves, can cool off again to second cooler.

Further specify specific structural features of the present invention and purpose below in conjunction with accompanying drawing.

Fig. 2: the internal unit schematic flow sheet that is high wind pressure air conditioner of the present invention.

[specific embodiment]

The present invention is a kind of high wind pressure air conditioner of two-part cooling, please referring to shown in Figure 2, it has first loop 20 and second loop 30, first loop 20 has compressor 21 in regular turn, condenser 22, filtering drying machine 23, the expansion valve 24 and first cooler 25, and all form the loop of a sealing therebetween with pipeline 26 connections, 30 in second loop is by external again second pipeline 31 of pipeline 26 before the expansion valve 24 in first loop 20, and second pipeline, 31 other ends are connected on the pipeline 26 behind first cooler 25 and form second loop 30, and be provided with the expansion valve 32 and second cooler 33 on second loop 30 in regular turn, the outside of second cooler 33 is to be provided with the outer cover 34 that two ends form opening, this outer cover 34 is to join with high pressure blower 35 towards a side of first cooler 25, and the outer cover opposite side then is connected with airduct 36.

During its running, compressor 21 is crossed condenser 22 with coolant feed, the expansion valve 24 in filtering drying machine 23 and two loops, after 32, cooling agent can rapid expansion also absorb first in a large number, two coolers 25, heat around 33, this moment, high pressure blower 35 can make air flow through first cooler 25 earlier, make first cooler 25 absorb the heat of air and form cold air, and water in air gas can condense in first cooler, 25 places simultaneously, then high pressure blower 35 makes this cold air flow towards second cooler, 33 directions again, treat promptly to be dry cold air by high pressure blower 35, right because cold air during through high pressure blower 35 because of at a high speed, the cause of high pressure friction, make the temperature of high pressure blower 35 outlets to rise about about 8 ℃ than inlet temperature, thereby second cooler 33 cold air can be cooled off again, because by being dry cold air around second cooler 33, import outer cover 34 inside so cold air can be forced, do not freeze on second cooler 33 and do not have condensate water, and, the cold air that desire transfers out from airduct 36 is compressed in outer cover 34 inside because all being compelled to import, again because be to connect to establish the less airduct of caliber 36 causes on the outer cover 34, thereby the speed of cold air conveying can be speeded, so that cold air is done the conveying of long distance.
