Description

[0001] SHIP REFRIGERATION UNIT WITH A SEMI-FLOODED EVAPORATOR [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ship freezing apparatus, and more particularly, to a ship freezing apparatus provided with a half-liquid evaporator capable of performing a gas-liquid separator function.

Generally, there is a disadvantage that the worker who needs to input ice by manual operation and the delay of the work time are delayed when moving the catches from the fishing line to the fish tank.

Therefore, there is a demand for a seawater cooling system capable of completely solving the problems occurring in the use of the sea ice while maintaining the leading of the catch by directly cooling the seawater stored in the fish bay by installing the seawater cooling system in the carrier ship itself.

When the freezer is installed on a ship, the installation location is inside the engine room. In the engine room, the equipment necessary for the operation of the existing vessel such as the main engine and the generator is installed.

Therefore, miniaturization of the marine refrigerator is extremely technically important, and therefore, an evaporator capable of reducing the size and achieving high performance is an important technique.

The refrigeration facility for cooling water for domestic fishing boats is not yet localized. In Japan, which is a fishery advanced country, there is a case where a half liquid evaporator is used for compacting.

In this case, the heat transfer pipe inside the liquid evaporator is disposed up to about 2/3 of the height of the evaporator shell, the liquid level of the refrigerant is kept slightly higher than the heat transfer pipe, and the upper portion is kept as an empty space for the gas- liquid separator so that the refrigerant liquid does not flow into the compressor suction pipe.

However, despite the empty space above the shell, the refrigerant is sucked into the compressor in a droplet state, causing oil dilution and bearing wear.

To solve this problem, a refrigeration system using a half-liquid evaporator is provided with a separate liquid-gas heat exchanger on the evaporator. However, the liquid-gas heat exchanger can contribute to the stability of the system, but the disadvantage of ensuring the installation space is a great restriction in the circumstances of the engine room of the ship.

Therefore, since the refrigeration system for ships or fishing boats is very restricted in installation space, it is required to install a liquid-gas heat exchanger into the half-shell evaporator shell to achieve compactness while securing the same function.

Currently, freshwater fishing vessels manage the freshness of fish by transporting and storing the fish by lowering the temperature by mixing the sea ice with the sea ice.

However, this approach has the disadvantage of increasing the cost of the ice due to the ice load and the ice-carrying load when the ice is being shipped from the ice making plant on the land, and the ice and salt by manual operation There is a disadvantage that the necessity of the work force and the working time are delayed.

Therefore, the seawater cooling system, which installs the seawater cooling system on the carrier itself to cool the stored seawater directly to maintain the freshness of the seawater and solve the problems in using the sea ice, And local development has begun as part of it.

Korean Patent Laid-Open No. 10-2012-0025664 (title of invention: absorption type refrigeration device for ship and absorption type refrigeration method)

It is therefore an object of the present invention to provide a refrigerant- And an object of the present invention is to provide a marine refrigeration apparatus provided with a half-size evaporator separately installed on an upper portion of an evaporator.

In addition, if a half-size liquid evaporator having a liquid-gas heat exchanger to be used with a gas-liquid separator in a sea water refrigeration system is installed on a ship, a liquid-gas heat exchanger It is another object of the present invention to provide a ship freezing apparatus having a half-size evaporator for making a compact, which is a problem of a marine refrigerator.

In order to accomplish the above object, the present invention provides a ship freezing apparatus provided with a half-evaporator, wherein the shell comprises a refrigerant, a cold water heat transfer pipe and a gas-liquid separator, and supplies cold air to a ship or a freezing warehouse 1. A marine refrigeration system comprising: a compressor for compressing a refrigerant vapor at a low temperature and a low pressure; A condenser connected to the compressor and using seawater as cooling water to condense the refrigerant vapor discharged from the compressor; A heat exchanger for exchanging a liquid-gas or a gas-gas using a refrigerant liquid or a refrigerant vapor at a high temperature and a high pressure; An electronic expansion valve connected to the heat exchanger to control and lower the temperature and pressure of the refrigerant discharged from the heat exchanger; A refrigerant liquid having passed through the electromagnetic expansion valve is accommodated in the shell, and a cold evaporator is communicated with the inside of the heat transfer tube; And a controller connected to the compressor, the condenser, the heat exchanger, the electronic expansion valve, and the half-liquid evaporator to control operations of the compressor, the condenser, the heat exchanger, the electronic expansion valve, and the half- And the heat exchanger may be provided in a part of the interior of the half-sized evaporator so that the half can be integrated with the liquid evaporator.

Further, it may further include an eliminator installed at an upper end of the half-size evaporator to remove excess water droplets remaining in the air to prevent wet compression.

The apparatus may further include a distributor installed at a lower end of the half-sized evaporator and distributing refrigerant having a lowered temperature and pressure through the electronic expansion valve evenly to the heat transfer tubes in the half-evaporator.

In addition,

When the refrigerant evaporated in the half-evaporator is overheated by the heat exchanger, the refrigerant can be controlled to flow into and out of the compressor.

In the ship freezing apparatus having the half-size liquid evaporator of the present invention, the liquid-gas heat exchanger occupying about 60% of the height of the evaporator is brought into the evaporator, thereby solving the problem of the volume of the heat exchanger even if the height of the evaporator is increased by about 4% It is possible to make the liquid evaporator compact.

FIG. 4 is a side view of the integrated evaporator and FIG. 5 is a block diagram showing the control system of the controller of the present invention. Referring to FIG.

As shown in FIGS. 3 to 5, the present invention relates to a ship freezing apparatus in which a shell is constituted by a refrigerant, a cold water heat transfer tube, and a gas-liquid separator and supplies cool air to a freezing warehouse provided on a ship or a ship using steam, An evaporator 10, a condenser 12, a heat exchanger 8, an electronic expansion valve 16, a half-liquid evaporator 25 and a controller 17.

The heat exchanger 8 can exchange liquid-gas or gas-gas using the refrigerant liquid 30 or the refrigerant vapor 9 at high temperature and high pressure.

The heat exchanger 8 may be provided in a part of the interior of the liquid evaporator 25 so as to be integral with the liquid evaporator 25.

The electronic expansion valve 16 may be connected to the heat exchanger 8 to control the temperature and pressure of the refrigerant liquid 7 discharged from the heat exchanger 8 to be lowered.

The refrigerant liquid 1 through the electromagnetic expansion valve 16 is accommodated in the shell and the cold water can communicate with the interior of the heat transfer pipe 23 in the half evaporator 25.

Semi-flooded type evaporator means evaporator in which 50% liquid and 50% gas are present in the evaporator and the refrigerant is supplied from the lower part of the evaporator to the upper part.

The controller 17 is connected to the compressor 10, the condenser 12, the heat exchanger 8, the electronic expansion valve 16 and the half-liquid evaporator 25 and is connected to the compressor 10, the condenser 12, (8), the electronic expansion valve (16) and the half-liquid evaporator (25).

 The controller 17 can control access to and from the compressor 10 of the heated refrigerant when the refrigerant vaporized in the half-evaporator 25 is overheated by the heat exchanger 8 or higher.

The half-liquid evaporator 25 of the present invention may further include an eliminator 6, an oil separator 11, and a distributor 2.

The eliminator (6) is installed at the upper end of the half-liquid evaporator (25) to remove excess water droplets remaining in the air to prevent wet compression.

The oil separator 11 is connected between the compressor 10 and the condenser 12, and a hole is formed in a part of the oil separator 11 to communicate with the outside air, and the gas and oil are separated from each other to discharge the gas to the outside.

The distributor 2 distributes the refrigerant whose temperature and pressure are lowered through the electromagnetic expansion valve 16 to the heat transfer tubes 22 and 23 in the half-liquid evaporator 25 at equal intervals .

A refrigerating apparatus for a ship having a half-height evaporator according to the present invention is installed in a ship freezer to produce cold water. A refrigerant liquid (1) of high temperature and high pressure coming from a condenser (12) The liquid-gas heat exchanger integral type half enters the liquid-gas heat exchanger 8 located at the upper part of the liquid evaporator 25 to increase the degree of superheat of the refrigerant gas entering the compressor 10 to protect the compressor 10 to stabilize the system .

At this time, the refrigerant liquid flowing out of the liquid-gas heat exchanger 8 is lowered in temperature and pressure in the electronic expansion valve 16, and enters the lower shell side of the evaporator 25.

The cold water recovered from the boats of the ship flows into the evaporator 25 of the present invention and is heat-exchanged with the refrigerant in the evaporator 25, and is supplied to the boiler or the like as cold water having a lower temperature.

The heat exchanger (8) is arranged to about 2/3 of the lower end of the evaporator, and the outside of the tube is heat-exchanged with the refrigerant liquid which is about 2/3 of the inside of the shell and the inside of the tube is heat- Becomes lower.

In the present invention, the refrigerant heat transfer tubes (22) are uniformly distributed throughout the bottom 2/3 of the inner bottom of the cylinder of the evaporator (25), and at the upper end outlet of the inside of the evaporator (25), an eliminator (6).

A distributor 2 is installed at the lower end of the evaporator 25 to uniformly distribute the refrigerant whose temperature and pressure have been lowered through the electronic expansion valve 16 to the heat transfer tubes 22 and 23 in the evaporator 25.

High-level and low-level transmitters 18 and 19 are provided to maintain the liquid level of the refrigerant in the evaporator 25, and the superheat degree control by the electromagnetic expansion valve 16 is used.

A refrigerant liquid flowing from the condenser 12 to the electronic expansion valve 16 flows into the piping of the liquid-gas heat exchanger 8 located in the upper part of the gas-liquid separator 5 inside the evaporator 25, The refrigerant vapor 9 evaporated in the heat exchanger 25 is heat-exchanged.

The refrigerant vapor 9 whose temperature has increased by the heat exchange enters the compressor 10 in a slightly overheated state, thereby protecting the compressor 10 by preventing wet compression (in this case, there is a risk of damage to the compressor).

This minimizes the formation of liquid droplets in the vapor sucked into the compressor 10 from the evaporator 25 so that the liquid-gas heat exchanger 8, which occupies a large volume, is not required separately, .

The refrigerant vapor sucked into the compressor 10 is compressed and the temperature and pressure are increased, and the refrigerant is introduced into the condenser 12 through the oil separator 11. The refrigerant vapor entering the shell side of the condenser 12 is condensed by heat exchange of the seawater as the cooling water 21 flowing into the heat transfer tubes 22 and 23 of the condenser 12 to be a refrigerant liquid.

The refrigerant liquid liquefied in the condenser 12 enters the liquid-gas heat exchanger 8 of the evaporator 25 to increase the degree of superheat of the refrigerant entering the compressor 10.

The liquid-gas heat exchanger (8) of the liquid-gas heat exchanger (8) functions as a liquid-gas heat exchanger in the liquid-gas heat exchanger (8) I can do it.

In this case, if the evaporator is made to be able to satisfy the volume of the evaporator due to the liquid-gas heat exchanger, the height of the evaporator is increased by about 4%.

That is, when the conventional evaporator and the liquid-gas heat exchanger are separately provided, the height space required for the liquid-gas heat exchanger is about 60% of the height of the evaporator, which is integrated into the inside by only about 4% of the existing evaporator. It is possible to make it compact.

Further, the liquid-gas heat exchanger can be provided in the gas-liquid separation space to secure a heat exchange area equal to that of the liquid-gas heat exchanger with a slight change in the diameter of the evaporator.
