Description

Cool & hot storage chamber < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cold and warm storehouse, and more particularly to a cold / hot storehouse that drives a warm store using waste heat discharged from a refrigerator.

Generally, a refrigerator is a device that keeps food inside a refrigerator fresh at a low temperature by performing a refrigeration cycle in which refrigerant compresses, condenses, expands, and evaporates.

A typical refrigerator has a main body provided with a freezer compartment, a refrigerating compartment, and a machine room. Conventionally, a large number of short-type refrigerators stacked up and down have been used in the refrigerating and freezing compartments. However, in recent years, the demand for the double-compartment refrigerators having both the refrigerating compartment and the freezing compartment partitioned on both sides based on the compartment extending in the longitudinal direction is larger. In the case of a machine room, it is usually provided on the lower rear side of the main body.

A compressor, a condenser, a cooling fan, and the like are installed in the machine room, and an evaporator is installed in the freezer room. In the refrigerant pipe between the condenser and the evaporator, an exchanger (inflator or expansion valve, hereinafter referred to as "inflator") is installed. Accordingly, the refrigerant compressed in the compressor is condensed in the condenser and then sent to the expander, and the refrigerant expanded in the expander flows into the compressor after passing through the evaporator. At this time, since the high-temperature refrigerant flows in the compressor and the condenser, the cooling fan is rotated in the machine room to cool the compressor and the condenser.

As the cooling fan rotates, the outside air flows into the machine room, and the outside air thus cooled is cooled after the compressor, the condenser and the like are cooled and then discharged to the outside. Accordingly, the efficiency of the cooling system can be improved by cooling the compressor and the condenser.

However, in the conventional refrigerator, since the waste heat generated in the condenser and the compressor is directly discharged, there is a problem that the amount of energy wasted in terms of energy efficiency is too large.

Particularly, in a mart or a convenience store that is equipped with both a refrigerator and a heating cabinet rather than a general household, the amount of energy consumed is comparable to that of a general household, .

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art as described above, and it is an object of the present invention to provide a refrigerator which can reduce the energy consumed in a warming room by using a waste heat, And to provide a cold durability so as to maximize efficiency.

The object of the present invention is to provide a cold storage device for use in a refrigeration cycle of a refrigerator, which is installed in the hot store and connected to a compressor of the refrigeration cycle, Providing auxiliary condenser; And a heat pipe installed at the one end of the hot runner and the other end of the heat pipe installed in the compressor of the refrigeration cycle to provide high temperature heat generated by the compressor to the hot runner.

The heat pipe further includes a heat dissipating plate for enhancing the heat dissipation effect. The compressor further includes a support member for supporting and fixing the heat pipe with the heat pipe inserted therein.

According to the cold storage of the present invention, the waste heat discharged from the refrigeration cycle of the refrigerator is used as an energy source to drive the heating warehouse, thereby reducing power consumption in the heating warehouse, saving energy, and maximizing energy efficiency.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing a cold-storage jig according to the present invention; FIG.

1 and 2, the cold storage 100 of the present invention includes a refrigerator 200 and a warm lamp 300, which are configured on a base 110.

A plurality of casters 111 are rotatably installed on a lower surface of the base 110, so that the cold storage 100 installed on the upper surface can be easily moved.

At this time, the caster 111 is preferably provided with a conventional brake means for stopping the rolling of the wheels.

A shelf 112 for installing the warming room 300 is provided on one side of the upper surface of the base 110 so as to protrude upward and the warming ware 300 is similar to the refrigerator 200 by the shelf 112 As shown in FIG.

The refrigerator 200 includes all conventional refrigerator. In the present embodiment, an ice cream freezer (hereinafter referred to as a "refrigerator"), which is mainly used in an ordinary mart or a convenience store, is exemplified as an example. However, Or < / RTI >

The refrigerator 200 is provided with a refrigeration cycle and the compressor 220 in which the high temperature heat is generated during the refrigeration cycle is drawn out to the shelf 112 of the base 110, Is installed on the shelf 112, the distance between the compressor 220 and the warming plate 300 is minimized, and the length of the heat pipe 340, which is expensive, can be minimized.

The compressor 220 installed in the shelf 112 is connected to the condenser 210 installed at the rear part of the refrigerator 200 and the evaporator 260 installed inside the refrigerator 200 through the main refrigerant pipe 230 ) To maintain the same refrigeration cycle as before.

The compressor 220 is connected to an auxiliary condenser 330 of an auxiliary warmer 300 and an auxiliary refrigerant tube 240 to be described later so that a part of the high temperature and high pressure refrigerant discharged from the compressor 220 is supplied to the heater 300 The refrigerant supplied to the auxiliary condenser 330 is circulated through the auxiliary condenser 330 and then discharged to the inflator 250 side of the refrigeration cycle through the auxiliary refrigerant pipe 240. At this time, the refrigerant discharged from the auxiliary condenser 330 is mixed with the refrigerant discharged from the condenser 210 of the refrigeration cycle, and then supplied to the inflator 250.

The warm lamp 300 is mounted on the shelf 112 of the base 110.

The heating lamp 300 includes a main body 310 for heating beverages stored therein and a door 320 rotatably installed on the main body 310 to open and close the main body 310.

The inner bottom surface of the main body 310 is usually provided with hot wire (not shown), and the beverage stored in the main body 310 is heated and held at a predetermined temperature. However, it is not enough to sufficiently heat the beverage stored in the main body 310 with such a hot wire alone. That is, since the hot wire is installed only on the bottom surface of the main body 310 on which the beverage is seated, only the bottom including the bottom surface of the beverage is intensively heated, and the upper portion of the beverage can not be heated sufficiently.

3, the heat pipe 340 and the auxiliary condenser 330 are installed on the rear surface (the surface opposite to the door 320) of the warming room 300 to solve the above-described disadvantages can do.

3, an auxiliary condenser 330 and a plurality of heat pipes 340 are installed on the rear surface of the main body 310 of the heating appliance 300 to supply high temperature heat into the main body 310 So that the beverage is heated together with the hot line on the bottom surface.

The auxiliary condenser 330 installed as described above is installed over most of the rear surface of the main body 310 of the warming room 300 and has the same structure and structure as the condenser 210 of the refrigeration cycle, And a blowing fan 331 for supplying high-temperature heat radiated from the auxiliary condenser 330 to the inside of the main body 310 is installed in the front part. Therefore, the efficiency of the heater 300 can be maximized by the blowing fan 331 installed as described above.

As described above, the auxiliary condenser 330 installed on the rear side of the warming room 300 may be replaced with the condenser 210 of the refrigeration cycle of the refrigerator 200, It is preferable to configure the condenser 210 in the refrigerator 200 and the auxiliary condenser 330 in the warmer 300. [

One end of the heat pipe 340 is installed on the rear surface of the warm lamp 300 under the auxiliary condenser 330 and the other end is installed in the compressor 220.

Particularly, the heat pipe 340 is constituted by a heat absorbing portion 341 at one end installed in the compressor 220 to absorb heat at a high temperature generated in the compressor 220, while the heat at the other end is changed in phase And a heat radiating portion 342 for radiating high-temperature heat to the outside.

The phase change of the heat pipe 340 occurs inside the heat pipe 340 as shown in FIG. 5, and the refrigerant stored in the heat pipe 340 is vaporized by the heat absorbed by the heat absorbing portion 341 Heat is absorbed by convection conduction in the heat dissipating unit 342 and is liquefied. Thus, the liquefied refrigerant is again moved toward the heat absorbing unit 341 side, and the heat absorbing and radiating functions are repeated.

A plurality of heat pipes 340 are provided in the heat dissipating unit 342 of the plurality of heat pipes 340 and a plurality of heat dissipating plates 350 are installed in the heat dissipating units 342 of the plurality of heat pipes 340, The conductivity of the heat dissipated in the heat dissipating portion 342 of the heat pipe 340 is improved.

The heat pipe 340 is fixed to the compressor 220 so that the heat pipe 340 can be firmly held in the heat absorbing portion 341 of the heat pipe 340, Member 360 is provided.

4, one end of the support member 360 is fixed to the compressor 220 and the other end thereof supports a plurality of heat pipes 340. At this time, A plurality of fixing grooves 361 to which the heat pipe 340 can be inserted and fixed are formed and the fixing groove 361 is formed to have an inner diameter corresponding to the heat pipe 340.

The operation of the cold dampener according to the present invention will now be described.

First, when the cold storage 100 is turned on, the refrigeration cycle is driven and the gaseous refrigerant compressed by the compressor 220 to high temperature and high pressure is supplied to the condenser 210 of the refrigerator 200 and the auxiliary condenser 330 The refrigerant passing through each of the condensers 210 and 330 is heat-exchanged with the atmosphere and is phase-changed into a refrigerant which is liquefied at a low temperature and a high pressure. The liquefied liquid refrigerant is supplied to the expander 250 Pressure is lowered while passing through the capillary, and is supplied to the evaporator 260 as a low-temperature low-pressure refrigerant. The low-temperature, low-pressure liquid refrigerant supplied to the evaporator 260 is vaporized while being deprived of heat by heat exchange, is phase-changed into low-temperature low-pressure gaseous refrigerant, and then supplied to the compressor 220 again.

Therefore, by supplying the high-temperature refrigerant to the condenser 210 of the refrigerator 200 and the auxiliary condenser 330 of the warming-up chamber 300 as described above, it is possible to prevent the waste heat from being discharged to the atmosphere from the condenser 210 of the refrigeration cycle By supplying a part of the power to the warming room 300, power consumption consumed in the warming room 300 can be reduced, energy can be saved, and energy efficiency can be maximized.

Furthermore, the heat generated by the compressor 220 generated during the process of compressing the low-temperature and low-pressure gas refrigerant to high temperature and high pressure is absorbed by the heat pipe 340 and dissipated into the interior of the warming room 300, The waste heat that has been abandoned as it is in the atmosphere is mostly absorbed by the heat pipe 340 having an excellent thermal conductivity and supplied to the warming room 300, thereby maximizing energy saving and energy efficiency.

The heat dissipation operation of the heat pipe 340 can be maximized by the heat dissipation plate 350 installed in the heat dissipation unit 342 of the heat pipe 340.

The high-temperature and high-pressure gas refrigerant discharged from the compressor 220 is heat-exchanged in the condenser 210 of the refrigerator 200 and the auxiliary condenser 330 of the warming-up chamber 300 and supplied to the inflator 250, The efficiency of the refrigeration cycle can also be maximized due to the rapid heat exchange.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the present invention is not limited to the disclosed exemplary embodiments, but various modifications may be made without departing from the spirit of the invention.
