Figure 15 is the stereogram that schematically represents the constitution equipment of the cool cycles unit in embodiment to be installed on the state of freezer 100.

As shown in figure 15, the cool cycles unit that freezer 100 has is the device with compressor (Compressor) 101, the first condenser (Condenser) 102, the second condenser 203 and the 3rd condenser 204 and evaporimeter (Evaporator) 105 and 106.

Condenser 102,103 and 104 consists of a series of radiating tube that forms the circulation path of cold-producing medium.Therefore, also can regard the first condenser 202, the second condenser 203 and the 3rd condenser 204 as a condenser.

In this cool cycles unit, by the first condenser 202, the second condenser 203 and the 3rd condenser 204 heat radiations, by evaporimeter 205 and 106, absorb heat.Thus, can make heat move forcibly to another space from a space.

Compressor 101 be compressive flow through the gasiform cold-producing medium of this cool cycles, improve the device of the pressure of cold-producing medium.

The first condenser 202, the second condenser 203 and the 3rd condenser 204 be the heat of the gasiform cold-producing medium that improves of release pressure with cooling refrigeration agent, the device of the liquid cold-producing medium that mineralization pressure is high.

The cold-producing medium of the cool cycles unit having as the freezer 100 of present embodiment, for example, adopt the cold-producing medium of hydrocarbon (hydrocarbon) class.

In addition, as the heat-barrier material being filled between outer container 156 and interior case 157, for example, adopt and using the pentamethylene (cyclopentane) of hydro carbons as the Foamex body of blowing agent.

Herein, the raw material of the hydro carbons adopting as cold-producing medium etc. have combustibility, but little on the impact of global warming.Therefore, as the cold-producing medium using etc., by adopting the raw material of hydro carbons, can greatly reduce the impact on global warming thus in freezer 100.

Evaporimeter 205 and 106 is the cold-producing medium gasifications that make via the first condenser 202, the second condenser 203 and the 3rd condenser 204, carrys out thus cooling device around.

In the present embodiment, evaporimeter 205 is disposed at the rear of the first casing 151, bears the indoor effect of cooling refrigeration.In addition, evaporimeter 206 is disposed at the rear of the second casing 152, bears the effect in cooling refrigerating chamber.

In addition, the second condenser 203 is disposed at the back side of the first casing 151 and the second casing 152 in the mode contacting with outer container 156.In addition, the 3rd condenser 204, along the peristome periphery above of the second casing 152, configures in the mode contacting with outer container 156.That is, heat insulation outer container 156 heat radiations of the second condenser 203 and the 3rd condenser 204.

The 3rd condenser 204 is the condensers of periphery that are disposed at the peristome of the second casing 152, also has the refrigerant cools of making simultaneously and the periphery of the peristome of the second casing 152 is heated up with the function of Antidewing.

When the mode according to above forms condenser, even in the situation that the ability that causes being exposed to the first condenser 202 in atmosphere because of accumulations such as dusts reduces, the second condenser 203 and the 3rd condenser 204 also can supplement the ability of condenser, therefore, without maintenance, just can keep for a long time the ability of cool cycles unit 110.

And, in the such large-scale freezer of SBS formula freezer, the freezer that the heat radiation of condenser is large as far as possible, the ability of its cool cycles unit strengthens, the length of the second condenser 203 that the free degree of elongated shape is higher as much as possible, thus, can promote the heat radiation of the second condenser 203, improve the efficiency of cool cycles unit.In addition, when the ability of the first condenser 202 reduces because of long-term running, also can keep condensing ability.

As shown in figure 16, the first vacuum heat insulation material 240, the second vacuum heat insulation material 241 are arranged at respectively the back side of the first casing 151 and the second casing 152, and the width of the second vacuum heat insulation material 241 is wider than the width of the second casing 152.In addition, between the first vacuum heat insulation material 240 and the second vacuum heat insulation material 241, be provided with gap, to guarantee vacuum heat insulation material can not contact each other, cause breakage.

In addition, near the mode contacting the crest line of the second condenser 203 with the back side with outer container 156 arranges, and forms two pipe arrangements by the M type shape in the gap of the first vacuum heat insulation material 240 and the second vacuum heat insulation material 241.

Herein, the width of the second vacuum heat insulation material 241 is wider than the width of the second casing 151, and therefore, the back side of the refrigerating chamber consisting of the second casing 152 is covered by vacuum heat insulation material completely, can improve thus the heat-proof quality of refrigerating chamber.

In addition, the pipe arrangement of the second condenser 203 is not positioned at the refrigerating chamber back side, can prevent that heat from invading to refrigerating chamber from the second condenser 203 yet.

As preventing that the method that heat is invaded from the second condenser 203 to refrigerating chamber from having, vacuum heat insulation material being implemented to the groove of the degree of depth that the pipe arrangement of the second condenser 203 passes through processes, vacuum heat insulation material and the second condenser 203 is overlapping, but, this method exists the processing charges of vacuum heat insulation material to increase, heat-proof quality variation, implements the problems such as the easy breakage of part that groove is processed.

Like this, the freezer 100 of present embodiment has the first vacuum heat insulation material 240～eight vacuum heat insulation material 247, and has the second condenser 203.Thus, can realize the raising of the capacity of taking in of freezer 100, and effectively cooling by what effectively heat insulation and heat radiation cool cycles unit brought.

In addition, in the present embodiment, even without the 3rd vacuum heat insulation material 242～eight vacuum heat insulation material 247, also can obtain same effect.

In addition, in the such SBS formula freezer of present embodiment, left and right is arranged ground and is formed storeroom, therefore, banner is made to wide cut.Therefore,, in the situation that vacuum heat insulation material is disposed to the back side, if adopt a vacuum heat insulation material to form, must use the wide vacuum heat insulation material of width.

The wide vacuum heat insulation material of this width must make equipment increase, and price increases, and warpage increase, therefore, easily contact with other parts in polyurethane, thus easily damaged.

In addition, near the mode contacting the crest line of the second condenser 203 with the back side with outer container 156 configures, and forms two pipe arrangements by the M type shape in the gap of the first vacuum heat insulation material 240 and the second vacuum heat insulation material 241.

According to this structure, first vacuum heat insulation material 240 at the back side of freezer 100 and the heat-proof quality between the second vacuum heat insulation material 241 reduce, and are subject to the impact from the heat in the low case of temperature, temperature step-down.But, because the second condenser 203 is by between the first vacuum heat insulation material 240 and the second vacuum heat insulation material 241, therefore, can improve back temperature.

Thus, the ability of the second condenser 102 can be improved, and in the situation that the humidity of outside air is high, the condensing back side at freezer 100 of airborne moisture can be prevented.

Herein, the width of the second vacuum heat insulation material 241 is wider than the width of the second casing 151, and therefore, the back side of the refrigerating chamber consisting of the second casing 152 is covered by vacuum heat insulation material completely, can improve the heat-proof quality of refrigerating chamber.

As preventing that the method that heat is invaded from the second condenser 203 to refrigerating chamber from having, vacuum heat insulation material being implemented to the groove of the degree of depth that the pipe arrangement of the second condenser 103 passes through processes, vacuum heat insulation material and the second condenser 203 is overlapping, but, this method exists the processing charges of vacuum heat insulation material to increase, heat-proof quality variation, implements the problems such as the easy breakage of part that groove is processed.

Like this, the freezer 100 of present embodiment has the first vacuum heat insulation material 240～eight vacuum heat insulation material 147, and has the second condenser 203.Thus, can realize the raising of the capacity of taking in of freezer 100, and effectively cooling by what effectively heat insulation and heat radiation cool cycles unit brought.

In addition, in the present embodiment, condenser consists of the first condenser 202, the second condenser 203 and the 3rd condenser 204, but, for example, in the situation that there is no the first condenser 202, in the situation that other condenser is located to configure in the side of freezer 100 and end face, bottom surface etc., also can obtain the effect of the ability that improves the second condenser.

(embodiment 3)

Body lower backside at freezer 100 has Machine Room 207, takes in compressor 101, the first condenser 202 and cooling fan 108 in inside.And the outer cover (not shown) that the peristome at the back side of Machine Room 207 is had suction inlet (not shown) and blow-off outlet (not shown) covers.In compressor 101 operation process, cooling fan 108 runnings shown in Figure 17, when cooling fan 108 running, outside air will be inhaled into from suction inlet, after cooling the first condenser 202 and compressor 101, from blow-off outlet, is blown.

Thus, the first condenser 202 becomes larger ability, can improve the efficiency of cool cycles.

But by utilizing cooling the first condenser 202 of cooling fan 108, therefore, cooling fan 108 picks up airborne dust, dust stops up the suction inlet of outer cover 109, likely makes the air quantity of cooling fan 108 reduce, and the ability of the first condenser 202 is reduced.In this case, the ability that the second condenser 203 and the 3rd condenser 204 supplement as condenser, therefore, Maintenance free just can keep the ability of cool cycles unit 110 for a long time.

In addition, for other effect, also can obtain the effect same with embodiment 2.Utilizability in industry
