Device cover 35 usefulness for example high material of thermal conductivity such as iron form, guide portion 38 also from top covering air supply direction upstream side enter the mouth about 1/4.
Also have, the outside (for example left side) of device cover 35 is being provided with electrical installation 40, has the control substrate (calling substrate in the following text) 39 that can control fan 30 and compressor 31.Substrate 39 is accommodated in and forms electrical installation 40 in the container 41, the opening portion of device cover 35 sealing electrical installations 40.Container 41 is provided with breakthrough part 42, by breakthrough part 42 usefulness leads 43 substrate 39 and fan 30, compressor 31 is electrically connected.Also have the container 41 of electrical installation 40 and 35 thermally coupleds on composition surface 44 of device cover.The encapsulant sealing that composition surface 44 and breakthrough part 42 usefulness aerations are low.
Introduce action, the effect of the refrigerator of said structure below.At first, according to the indication of substrate 39, compressor 31 entrys into service, also entry into service of fan 30 simultaneously, the top of the air entry 37 of air the past grid 25 and the wind path upstream side of device cover 35 is inhaled in the device cover 35.Air carries out heat exchange through condenser 29, and after temperature raise, order was collided with wall 23 through device cover 35 then by the periphery separately of fan 30, compressor 29.The space U font of air between the outside of wall 22,24,26 and device cover 35 turned and passed through then, becomes the peristome 50 of ascending air above Machine Room 21 and slowly discharges.
Also have, just in case cold-producing medium 34 is during from pipe arrangement 32 leakages, the cold-producing medium 34 of leakage is through the running of fan 30, diluted by air during together by the exhaust passage with air.And be reduced to below the flammable concentration, the peristome 50 on 21 tops is slowly discharged from the Machine Room.When if cold-producing medium leaks near the inlet of wind path (air supply direction) upstream of device cover 35, the cold-producing medium 34 of leakage is just forced to import wind path (air supply direction) upstream side of condenser 29 by device cover 35 guide portion 38.Then with air together by the exhaust passage, diluted by air and discharge.
Like this, the cold-producing medium 34 of the leakage of carrying in the hot-fluid of Machine Room 21 is not to concentrate on the local area, but is diffused into the space of 21 tops, Machine Room.Therefore, ligthing paraphernalias such as fluorescent lamp are arranged, may become the burning things which may cause a fire disaster of cold-producing medium 34 even worry to be provided with near ceiling main body 20 local etc., can breaking out of fire yet, can guarantee security.
This point is particularly important as the professional time spent with refrigerator.This is because professional illumination such as kitchen and the cooking device etc. of being arranged on refrigerator might become in the more environment of the factor of combustible refrigerant burning things which may cause a fire disaster.Professional with the big height height of the big multicapacity of refrigerator, be easy to cause the approaching condition of ligthing paraphernalias such as fluorescent lamp with installing on the ceiling.Therefore, when existing refrigerator was directionally forced heat extraction from the front of the Machine Room that is located at its top, heat extraction stream arrived the ligthing paraphernalia that may become burning things which may cause a fire disaster simultaneously partly with cold-producing medium 34, in the worst case may breaking out of fire.To this, have the refrigerator of the condensing unit 27 of present embodiment, even near the place ahead ceiling the main body 20 ligthing paraphernalia is arranged, cold-producing medium 34 can not discharge to the part yet.Cold-producing medium 34 diffusion is discharged into the upper space of main body 20, then, because the proportion of cold-producing medium 34 is heavier than air, cold-producing medium 34 dispersion that slowly descends in the whole space that refrigerator is set.Therefore, environment can not satisfy the concentration of catching fire, and can keep security.
Also have, the heat that the substrate 39 in the electrical installation 40 produces carries out effective heat exchange via the device cover 35 that the high material of heat conductivity forms with air, rises with this temperature that suppresses substrate 39.Even just in case cold-producing medium 34 covers 35 internal leakages at device, and through near the exhausts electrical installation 40, encapsulant 45 can prevent that also cold-producing medium 34 from entering in the electrical installation 40.Therefore can prevent that substrate 39 from becoming burning things which may cause a fire disaster and catch fire, explode.
As mentioned above, in the present embodiment, to the both sides of major general's condenser 29, fan 30, pipe arrangement 32 and connecting portion 33 and top with do not cover as far as possible with the device cover 35 of the size of condenser 29 devices spaced apart.The heat that such structure can make condenser 29 produce has no the ground of delay row outside device cover 35.That is, be diffused into the upper space of Machine Room 21 from the heat extraction stream of condensing unit 27.Therefore the temperature that the air quantity that does not need to increase fan 30 can suppress condenser 29 rises, and reduces power consumption.
Also have, device cover 35 covers pipe arrangement 32 and connecting portions 33, so can prevent to install the time and more the changing device mistiming contacts pipe arrangement 32 and connecting portion 33, makes cold-producing medium 34 leakages.When particularly using combustible refrigerant, can improve security as cold-producing medium 34.
Also have, even just in case cold-producing medium 34 is installing cover 35 internal leakages, the cold-producing medium 34 of leakage is discharged to outside the Machine Room 21 after can contacting with device cover 35 and spreading.Therefore, can prevent that the cold-producing medium 34 of high concentration is discharged to outside the Machine Room 21 quickly, improve security.
Also have, the back partition wall 23 of main body 20 is being set as shield 36A.Thus, just in case cold-producing medium 34 is when 35 internal leakages of device cover, the cold-producing medium of leakage can with 35 collisions of device cover after, under the ventilation of fan 30, contact the back with wall 23 and spreads, until discharge.Therefore can further improve security.
Also have, also be provided with cross section in the both sides of device cover 35 and roughly be parting next door 22 on the left side and parting next door 24 on the right side of L font as shield 36B, and and device cover 35 between form wind path.The temperature of the cold-producing medium 34 that leaks raises, and when spreading energetically with ascending air, after touching wall 23,26, row is spread behind 21 tops, Machine Room.On the other hand, the temperature of the cold-producing medium 34 of leakage reduces in the time of can not promoting to spread, and the heavier-than-air cold-producing medium 34 of proportion is touching wall 23,26 back sinkings, so almost can not be discharged to 21 tops, Machine Room.Here, owing to be provided with wall 22,24, cold-producing medium 34 covers between 35 by wall 22,24 and device, once more short circuit and the wind path upstream portion of return mechanism cover 35.And and be discharged to 21 tops, Machine Room behind the air mixed diluting gradually, so can further improve security.
In addition, partition wall 26 is arranged to the part of shield 36A above.Thus, when for example there is wall at main body 20 back sides, can prevent that the leakage of refrigerant of running into wall 23 from can rise rapidly along wall, for example touch fluorescent lamp etc. and breaking out of fire, blast.Can further improve security like this.
Also have, wall 22,23,24,26 is used as shield 36A, the 36B that the cross section roughly is the L font, can reduce amount of parts, reduces cost.The device cover 35 of preferred condensing unit 27 and at least a portion of shield 36A, 36B are integrally formed by main body 20.Like this, but the part double as main body 20 of device cover 35 and shield 36A, 36B can reduce number of components and parts thus, helps to reduce cost.
Also have, by on the part of the covering condenser 29 of device cover 35 peristome 50 being set, and open to ambient atmos, condenser 29 heat radiations can suppress the temperature rising of condenser 29 easily.Can reduce power consumption like this.
Also have, top overlapping by with wall 26 and device cover 35 prolongs the exhaust channel of the cold-producing medium 34 of device cover 35 internal leakages.Owing to separating with the degree that can form wind path the space of exhaust channel is broadened, therefore exhaust rapidly is suppressed.Cold-producing medium 34 is further diluted before being discharged from, and concentration drops under the flammable concentration, and slowly discharges above whole device cover 35.Therefore, the cold-producing medium that is lower than flammable concentration is slowly discharged with the ascending air of the air that becomes high temperature by the heat exchange with condenser 29, can prevent that the cold-producing medium of flammable concentration from arriving burning things which may cause a fire disaster, guarantees security.
In addition, in the present embodiment, the distance between device cover 35 and wall 22, device cover 35 and the wall 24 equates.But, when being arranged on electrical installation 40 on the exhaust channel, consider the wind path resistance that causes thus, strengthen the wind path that is arranged on electrical installation 40 sides, be comparatively desirable preventing on this meaning of exhaust rapidly.
In addition, in the present embodiment, device cover 35 covers the both sides and the top of connecting portion 33, and the top of wall 26 and device cover 35 is overlapping, but is not limited in this.Pipe arrangement 32 and connecting portion 33 are positioned at from the Machine Room when 21 tops are down about 150mm, also can not adopt said structure, and pipe arrangement 32 and connecting portion 33 are opened to the outside of Machine Room 21.When this structure can make cold-producing medium 34 contingency leak from installing cover 35 unlapped pipe arrangements 32, directly cold-producing medium 34 is arranged to 21 tops, Machine Room.But the exhaust channel about from place that cold-producing medium 34 leaks to the 150mm on 21 tops, Machine Room, cold-producing medium 34 is diluted by air.Therefore, cold-producing medium 34 is lowered to outside the following discharge of the flammable concentration Machine Room 21, can guarantee security.And, owing to reduced the wind path resistance of fan 30, increased aeration, rise so can further suppress the temperature of condenser 29, reduce power consumption.
Also have, by guide portion 38 is set, even when cold-producing medium 34 leaks near the inlet of the wind path upstream of device cover 35, but the also wind path of directed section 38 guiding fans 30 of the cold-producing medium of leakage.Therefore, can prevent directly discharging outside Machine Room 21, further improve security.
Also have, by making device cover 35 with the high material of heat conductivity, the heat of condenser 29 can be arranged to ambient atmos through device cover 35 at an easy rate.Thus, the temperature that can further suppress condenser 29 rises, and reduces power consumption.In addition, the material of constituent apparatus cover 35 is preferably metal materials such as steel plate, and thermal conductivity factor is preferably more than the 10W/mK.
Also have, when the condensing unit 27 in the Machine Room 21 had electrical installation 40, the heat sink that the part of device cover 35 can be used as electrical installation 40 played a role.By this structure, the heat that substrate 39 produces in electrical installation 40 can be discharged to the outside through device cover 35.Therefore, the temperature that can suppress substrate 39 rises, and guarantees the security of substrate 39, increases the service life.
Also have, Machine Room 21 is grid 25 before wind path (air supply direction) upstream of condensing unit 27 has, so can't see condensing unit 27 from the outside of main body 20, has improved appearance design.
As mentioned above, in the condensing unit of use combustible refrigerant of the present invention, by covering pipe arrangement portion by the device cover, the temperature that can suppress condenser rises, and reduces power consumption.Also have, even under the situation that the contingency combustible refrigerant leaks from pipe arrangement portion, also can guarantee security.This condensing unit also can be used on other equipment that utilize freeze cycle except refrigerator.
