Description

Cooling system {COOLING APPARATUS}

The present invention relates to a cooling device, and more particularly, when warm outside air is introduced, by lowering the pressure of the high-pressure liquid refrigerant filled in one evaporator and moving it to the other evaporator, the cooling efficiency is maximized and the generation of heat is lowered, thereby global warming It relates to a cooling system that can prevent in advance.

As is well known, the air conditioner is a mechanical device that lowers the indoor temperature or maintains it in a comfortable state.

It adjusts a certain space to an appropriate temperature, humidity, and airflow distribution suitable for human activities, and at the same time removes dust in the air. The comfortable indoor temperature varies from person to person, but in summer, the temperature difference from the outside air is 5~6℃, indoor temperature is 25~29℃, humidity is 60~70%, and in winter, indoor temperature is 18~21℃, humidity 55-70% is appropriate.

The principle of the air conditioner is to use the heat of evaporation that takes heat away from the surroundings when the liquid evaporates like a refrigerator or a refrigerator. The basic structure of the air conditioner is to directly connect an electric motor and a compressor in a sealed iron container, and the electric motor rotates the compressor to compress the refrigerant.

There are two types of compressors: reciprocating and rotary.

The condenser is an aluminum pin mounted on the surface of the copper pipe, and acts to cool and liquefy by dissipating the heat of the refrigerant into the air.

The expansion valve is a device that lowers the pressure of the high-pressure liquid refrigerant coming out of the condenser so that it evaporates in the subsequent evaporator, and a thin copper pipe with an inner diameter of about 1mm is used.

The structure of the evaporator is almost the same as that of the condenser, where the compressed refrigerant evaporates and takes heat from the surroundings. Therefore, the temperature of the air in contact with the evaporator surface is lowered, and moisture in the air is removed as water droplets on the surface of the evaporator. The blower system is forced to send air for efficient heat exchange.

The above-described cooling device liquefies the refrigerant compressed in the compressor in the condenser, passes through the expansion valve, lowers it, and evaporates in the evaporator to cool the room through a cycle to take away the surrounding heat. Keep it comfortable.

4 is a block diagram schematically showing a prior art air conditioner.

Referring to FIG. 4 , the cooling device of the prior art includes a compressor 11 for compressing a refrigerant to a high temperature and high pressure, a condenser 12 for liquefying the refrigerant into a high pressure liquid refrigerant, and an expansion valve 13 for lowering the pressure of the high pressure liquid refrigerant ), and an evaporator 14 for evaporating the liquid refrigerant to take away the surrounding heat.

Accordingly, in the prior art, the compression-condensation-expansion-evaporation process of the refrigerant in the compressor 11, the condenser 12, the expansion valve 13 and the evaporator 14 is repeated, and at this time, the refrigerant in the evaporator 14 When it evaporates, it cools the room by taking away the heat from the surroundings.

In the prior art, Freon gas is used as a refrigerant. This Freon gas is not decomposed after it comes out into the air, so its use was banned in 1987 as it was found to be an environmental pollution factor that destroys the ozone layer in the stratosphere.

As an alternative refrigerant for such Freon gas, brine, which maintains a liquid state at -50°C and is inexpensive and less corrosive, is used, but this brine is also not suitable for food and may cause various side effects.

That is, the above-described prior art has a problem of causing environmental pollution and various side effects because the refrigerant is excessively used.

In addition, the prior art has a problem of causing global warming due to the high-temperature heat generated during the cycle of the air conditioner.

The technical idea is to convert the refrigerant in the direction of the moved evaporator by control.

The present invention may further include a shut-off valve for controlling the movement of the refrigerant of the first evaporator to the second evaporator through the expansion valve or controlling the movement of the refrigerant of the second evaporator through the expansion valve to the first evaporator there is.

The first evaporator may include a sealed first body, a plurality of first evaporators installed in the first body to cool and exhaust the cold air sucked in through the first intake port, and external air flowing through the first evaporator to cool the first evaporator. It may contain a refrigerant that evaporates.

The second evaporator may include a sealed second body, a plurality of second evaporators installed in the second body to cool and discharge the cold air sucked in through the second intake port, and external air flowing through the second evaporator to cool the second evaporator. It may contain a refrigerant that evaporates.

The shut-off valve may regulate the expansion valve.

According to the present invention implemented as the above-mentioned solution, since the first and second evaporators are selectively operated using the limited refrigerant to cool the outside air, it is possible to reduce the use of the refrigerant, which can cause environmental pollution and various side effects, and for cooling. There is a very useful effect that can prevent global warming in advance by reducing the high-temperature heat generated during the cycle of the device. In addition, if the size is increased, it is possible to produce a large amount of energy and is effective in preventing global warming.
