Description

[0001] REACH-IN TYPE COLD STORAGE FOR SHIP [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a rich-in-kind ship freezing warehouse, and more particularly, to an improved rich-in-kind ship freezing warehouse capable of performing the most efficient food freezing warehouse function within a limited space defined as a ship.

There are two types of methods for constructing refrigerated warehouses on board: Conventional Construction Law, in which heat-insulating built-in works, related works such as carpenters, electricity, painting, plumbing, Called "Walk-in System" in which a cold storage warehouse is assembled on board by using a so-called sandwich heat-radiating finishing board wrapped by a stainless steel plate or galvanized steel plate such as urethane foam with excellent heat dissipation effect. There are different kinds.

However, as the development of food processing technology and the taste of food have changed recently, more than half of the foodstuffs of the shipping crews have been converted into a form that is packed and shipped with cans, PET bottles or plastic vacuum containers, It is not necessary to store them in a freezing warehouse), and it is satisfactorily satisfactory even by simply storing them in a dry provision store which is kept in a calm state in most residential areas, so that a large-sized food freezing warehouse is not required .

In the case of a frozen food storage warehouse by the conventional construction method or a walk-in system (Walk-in System), the refrigeration cycle must be operated regardless of the amount of stored food, If unnecessary energy loss occurs and an abnormality occurs in the freezing device, the frozen state of the entire refrigeration warehouse is stopped, thereby causing a serious disadvantage in causing a serious disruption to the food supply of the crew as well as the food hygiene.

In this connection, Patent Publication No. 1982-0001868 is known as a prior art, which is a system used in refrigerated container ships, that is, a refrigeration warehouse for cargo, and thus is independent of the present invention and disclosed in Japanese Laid-Open Patent Publication No. 2012-0025664 The present invention relates to a refrigeration cycle itself for recovering waste heat of a ship engine to realize an efficient refrigeration warehouse.

Therefore, in connection with the present invention, it is urgently required to provide a new refrigeration system that is efficient and can reduce the installation cost, while positively coping with changes in food intake of crew members.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-mentioned problems and limitations in the prior art, and it is an object of the present invention to improve the structure of a refrigeration warehouse provided in a ship according to the development of food processing technology, The main objective of the present invention is to provide a new concept of a rich-in-ship freezing warehouse for a ship, which reduces power consumption, installation cost, and operation efficiency based on the decentralized refrigeration control technology.

In order to achieve the above object, the present invention provides a refrigeration warehouse provided in a ship for storing the expression of beverages and beverages, comprising: a refrigerating compartment (110) individually driven and a refrigerating compartment (120) A plurality of freezers 100 are arranged in a distributed manner in accordance with the capacity calculated according to the number of crew members, the refrigerator storage 120 is disposed at the inlet side, and the freezer storage 110 is disposed at a distance from the inlet side. A refrigerated storage compartment 120 and a freezing compartment 110 are arranged; The refrigerator / freezer 100 includes a pair of separate doors 160 that can be individually opened and closed, a central partition 130 separating the inside of the refrigerator / freezer 100 in the width direction and seating the ship 140, And the lower portion are configured to communicate with each other; An evaporator 180 and a blowing fan 170 for indirect cooling and circulation are installed on the inner ceiling of the refrigerator / freezer 100; A compressor 190 connected to the evaporator 180 is installed on the upper outer side of the refrigerator / freezer 100 to shorten the length of the refrigerant pipe.

According to the present invention, a marine refrigeration warehouse for storing foodstuffs that are stocks of crew members is constructed as a distributed control type and can be individually controlled, thereby reducing power consumption, reducing installation cost, and using other freezers It is possible to prevent the food from being corrupted or deteriorated, thereby maximizing the operation efficiency.

FIG. 1 and FIG. 2 are exemplary flat cross-sectional views of a freezing warehouse according to the prior art and a freeze storage warehouse for a ship according to the present invention.
3 and 4 are views illustrating an example of a freezer implementing a rich-in-ship marine refrigeration warehouse according to the present invention.
5 is an exemplary circuit diagram for controlling operations of a rich-in-ship ship freezing warehouse according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

The term " Reach-in System " according to the present invention refers to a refrigeration system for display, which means a refrigeration system that can be easily accessed and arranged so that it can be easily handed, Freezer.

However, such a rich-in-freezer is mainly limited to those used in a large-scale mart or supermarket, and has not been attempted so far because of its limited structure and in a structure such as a ship constructed for a special purpose.

In view of this point, the present invention has been made in view of this point, and it is an object of the present invention to provide a food processing method and a food processing method capable of accommodating changed food storage forms through a decentralized control method instead of a centralized control method in a narrow space such as a ship, It is created so that it can be safely stored and secured the health of the crew members and the safety of foodstuffs. Therefore, unlike rich in-freezer, terms are defined and used as rich in-system.

In addition, the refrigerating warehouse used in the present invention, that is, the freezer or the refrigerator, has the same concept as the commonly used household appliance refrigerator, but has a different concept from that of the conventional refrigerator, and a freezing cycle (compressor → condenser → capillary tube → evaporator The compressor → the compressor) is already known, so the description of the refrigeration cycle will be omitted.

As shown in FIGS. 1 and 2, the rich-in-ship ship freezing warehouse according to the present invention is a conventional cold-chamber type freezing Unlike a warehouse, it is composed of individual controlled types, that is, distributed controlled type freezing warehouses as shown in (b).

At this time, the size of the freezing warehouse is the same as the conventional one. In other words, it is possible to efficiently distribute and distribute the same space inside the ship as in the prior art.

In addition, since the conventional cold-chamber type freezing warehouse must have a thorough heat insulating wall 10 and be able to enter and exit through the main door 20 and each door having a complicated structure must be provided so as not to hinder the heat insulating performance, In terms of utilization, it was a very disadvantageous structure in terms of cold preservation.

In addition, since it is a centralized control system, one refrigeration unit is installed in a separate space outside the engine room, and cold air is generated through the piping, so that the construction is complicated and the interference and collision phenomena with other facilities are large I was subject to many restrictions.

On the contrary, the distributed controlled rich-in-ship ship freezing warehouse according to the present invention does not need to construct a heat insulating wall, nor need to construct a separate lobby centering on the main door, It is convenient to use the refrigerator / freezer 100 because the structure is simple, there is no fear of interference, and the copper wire is efficiently secured.

In addition, since each refrigerator / freezer 100 is individually controlled, it does not affect other refrigerator / freezer even in the event of a failure, and there is no possibility that the stored foodstuff will be altered.

The refrigerator / freezer 100 may be arranged in an M-shape as shown in FIG. 1 (b) or in an in-line manner as shown in FIG. 2 (b).

However, it is not necessary to limit the arrangement of the refrigerator / freezer 100 to a specific arrangement because it is necessary to design an efficient and optimum copper line considering the size and structure of the refrigerator warehouse provided on the ship. However, M, E, C, or shape, or a combination of these arrangements is most reasonable.

As shown in FIGS. 3 and 4, the refrigerator / freezer 100 constituting the rich-in system according to the present invention is formed in the form of an individual storage container rather than a conventional warehouse type, and is configured to have a refrigeration or freezing function do.

In particular, the refrigerator / freezer 100 has a capacity of 1000 liters and a capacity of 1500 liters so that the number of seats can be adjusted in accordance with the number of seafarers so that the seafood can be stored for a long period of time I will.

At this time, among the refrigerator / freezer 100, the refrigerator 110 having a refrigeration function is limited to a temperature of -18 ° C to -21 ° C so that the meat and fish can be frozen and stored, and the refrigerator 120, Is kept at + 1 ℃ ~ + 5 ℃, so that it can store vegetables, cans and canned foods.

In other words, the cryopreservation 110 and the refrigerated storage 120 have the same structure, but are provided separately, and the arrangement of the cryopreservation 110 and the position of the refrigerating storage 120, The location of the array can vary.

Preferably, the refrigerating compartment 120 should be arranged first, and the freezing compartment 110 should be arranged on the far side from the inlet, since the compartment must be arranged mainly for refrigerated food which is easy to take out from the vicinity of the inlet and can be taken out within a short period.

In particular, the refrigerator / freezer 100 according to the present invention is provided with a shelf 140 having the same structure on both sides of a central partition wall 130, unlike an appliance refrigerator generally available in the market, so as to maximize the storage capacity The upper and lower portions of the central partition 130 are opened so that the two side spaces partitioned by the central partition 130 are not divided into independent rooms but are communicated with each other, 130 and the both side walls 150.

The door 160 has a structure in which two doors 160 are provided per one refrigerator / freezer compartment 100 so as to be openable and closable by being divided into two at the center partition wall 130, The storage can be easily and quickly taken out or stored.

That is, it is considered that the refrigerator / freezer (100) structure which is not independently cooled but has a special processing adapted to the ship by employing an independent door.

A blower fan 170 for circulating the inside of the room and an evaporator 180 for generating cold air are provided on the front surface of each storage tank and a display for setting the internal temperature or checking the current temperature is provided outside do.

In addition, a defrost heater (not shown) for defrosting is provided under the evaporator 180, and a condenser including the compressor 190 is installed separately at the upper and outer surfaces of the upper ends of the respective reservoirs .

At this time, the reason why the compressor 190 is formed on the outer surface of the upper end of each reservoir is that the flow path of the refrigerant pipe is made as short as possible to facilitate the installation, the installation space is minimized and the space is efficiently used to reduce the equipment cost, .

The shelf for a marine vessel of the rich in-line type according to the present invention having such a configuration is controlled according to a circuit diagram as shown in FIG.

That is, as shown in FIG. 5, when the power switch SW is turned on, the power lamp L1 is turned on and the digital thermostat D is powered on.

Thus, the relay RY1 is excited, the D-a contact is closed, and the relay RY3 is excited.

Therefore, the relay RY4 for the blowing fan 170 of the evaporator 180 is excited, and RY5 is also excited.

At this time, the contact of the relay RY1 is closed, the compressor 190 and the blowing fan 170 operate, and a lamp installed on a separate panel is turned on to indicate a normal operation state.

When the contacts of the relays RY3, RY4, and RY5 are closed and the blowing fan 170 operates, the temperature inside each of the storage bases 110 and 120 is cooled by indirect cooling.

When the temperature inside each of the reservoirs 110 and 120 falls below the set temperature, the thermal cut-out contact is closed and the relay RY2 is excited. When the contact of RY2 is closed, the defrost heater is operated .

At this time, it is possible to add a lamp on a separate panel to recognize the state of defrosting.

Further, during defrosting, the operation of the compressor 190 is stopped, the running lamp on the panel is turned off, and the defrost lamp is turned on.

In addition, when the internal temperature of each reservoir (110, 120) rises above the set temperature due to abnormal operation, the alarm is turned on by the thermostat (thermostat) ON), and the buzzer sounds to recognize the abnormal state.

At this time, when an abnormal situation is detected, a manual return push button may be installed to arbitrarily cut off the buzzer sound. Including this feature increases convenience and manageability.

And, as one of the types of failure that can be expected, if the digital thermostat (CUT) contact of the digital thermostat does not operate, the internal temperature may rise if the RY2 keeps closing to stop the defrosting operation.

Therefore, the advantage of the present system is that the above operation situation can be quickly recognized in case of a failure that may occur on one panel of a plurality of equipment states at a specific place in a remote place.

In addition, a digital thermostat may be additionally installed on the panel to detect the temperature inside the storage basins 110 and 120 in real time.

In addition, a control panel or a display is electrically connected to monitor the state (operation, failure, etc.) of each refrigerator / freezer 100 in an engine control room (ECR) The refrigerator / freezer 100 may be configured to be turned off when a problem occurs in the refrigerator / freezer 100.

At this time, the ECR is a space provided for monitoring the battlefield area.

In addition, this operation is controlled through a control unit, for example, a CPU unit such as a microprocessor.

As such, the rich in-system according to the present invention can efficiently manage and control different types of distributed control systems, reduce installation and maintenance costs, and provide a system suitable for storing foodstuffs of changed crews .
