The present invention relates to a hybrid air conditioner, and more particularly, to a hybrid air conditioner to maximize the heating and cooling efficiency to reduce installation and maintenance costs, to prevent the risk of fire and to prevent environmental pollution.

In general, the refrigeration technology is the refrigerant compression by the evaporative heat by repeated compression and expansion of the compression compressor is the predominant, and in order to keep up with the recent energy saving trend, absorption refrigerators and the like are used a lot. In addition to the general refrigeration technology, refrigeration technology using a special method has been developed and applied at home and abroad with the recent development of high-tech industry, and is gradually expanding its scope.

Refrigeration and air conditioning technology artificially maintains temperature, humidity, airflow, and cleanliness in the most suitable state for people, goods, and machinery in the room, and is classified into general air conditioning and industrial air conditioning. Currently, the refrigeration and air-conditioning industry is an industry that designs, manufactures, constructs, and manages various mechanical equipment such as air conditioning equipment, refrigeration equipment, sanitary equipment, building environment equipment, and plant equipment. It is applied to all modern industrial fields such as building equipment, food, pharmaceuticals, aerospace, and environmental devices, and is applied to the industry as it is essential to almost all production process environments.Storage, distribution, exhibition of frozen foods, pharmaceuticals, etc. It is also used as a commercial and refrigerator, home air conditioner, and automotive air conditioner.

Recently, the refrigeration and air conditioning industry is a necessity of modern civilized life and high industrial technology environment, which has been expanded in various industrial environments through high performance, miniaturization, energy saving, low noise, and environment-friendly technology development. In addition, the indoor environment requiring high clean conditions such as the rapid development of building equipment by the emergence of intelligent buildings by office automation, the production process of high-tech electronic semiconductor industry, and the bio-technology related facilities by genetic engineering development Demand is also expanding, and there is an urgent need for high-performance, high-efficiency, low-noise refrigeration and air conditioning in the automotive sector.

A refrigeration cycle is a cycle of refrigeration during the return to its original state. In the refrigerating device, the refrigerant enters the evaporator after the low pressure through the expansion valve, the liquid refrigerant takes evaporation latent heat to evaporate. The evaporated refrigerant vapor receives work from the outside, that is, the work is received from the outside in the compressor, and compresses the refrigerant vapor to high temperature and high pressure. Compressed high-pressure steam is sent to the condenser where it releases and condenses the heat of condensation. The condensate forms a cycle back into the expansion valve. The refrigerant circulates constantly, either continuously or as a gas in the refrigeration unit.

The refrigeration cycle is divided into compression process, condensation process, expansion process, and evaporation process. Each of these processes consists of four main components: ① compressor ② condenser ③ expansion valve ④ evaporator. It can be said that it is equipped with an electronic controller in order to control the flow of the refrigerant by connecting it to the (copper pipe) and filling the refrigerant therein.

Currently, refrigeration cycles include ammonia, fluorinated hydrocarbon-based refrigerants (freons), azeotropic mixed refrigerants, and methyl chloride, among which freons are not allowed to be the main culprit of ozone depletion. It is becoming. That is, since the conventional refrigerant is mostly the material that destroys or pollutes the environment, especially products requiring large size, it is urgently required to cope with the environmental pollution due to the use of a large amount of refrigerant proportionally. In this sense, alternative or mixed refrigerants, which are being developed by companies and research institutes, require continuous research results according to the characteristics of the refrigerants, and there is a problem that the design changes of existing products according to the developed refrigerants are to be followed.

In addition, since the materials used as conventional refrigerants are materials that are not easily handled by the general public, they require considerable time and cost for repair and maintenance in the event of product failure. Therefore, the vulnerable structure that can cause huge loss for the original product recovery is not being improved.

The object of the present invention devised in view of the above problems is to provide a hybrid liquid air conditioner to make the most of the refrigerant material used in the existing refrigeration cycle while contributing to environmental protection.

Another object of the present invention is to provide a hybrid liquid air conditioner that can be easily managed by the general public to enable first aid with minimal cost and effort.

The present invention for achieving the above object, an instant cooler for producing a liquid refrigerant; A liquid refrigerant air conditioner for cooling a closed space required by circulating the liquid refrigerant in a low temperature state generated by the instantaneous cooler; And a connection flow path connecting the instantaneous cooler and the liquid refrigerant air conditioner.

An evaporator for instant cooling to heat exchange the material.

The instantaneous cooling evaporator includes a refrigerant case through which the refrigerant passes, and a target material channel installed in a zigzag shape having a longest length inside the refrigerant case to exchange heat with the refrigerant while the object passes therethrough.

The liquid refrigerant air conditioner is a heat exchanger for heat-exchanging cold air required in the closed space using a low-temperature liquid refrigerant generated in the instantaneous cooling evaporator, and a blower fan for discharging cold air heat-exchanged by the heat exchanger into the room It includes.

There is provided a tank for collecting the liquid refrigerant between the instantaneous cooler and the liquid refrigerant air conditioner, wherein the tank is a first tank for collecting the low-temperature liquid refrigerant produced in the instantaneous cooler, and heat exchange in the heat exchanger And a second tank for collecting the liquid refrigerant in a high temperature state.

The apparatus may further include a first pump for supplying the liquid refrigerant from the first tank to the liquid refrigerant air conditioner, and a second pump for recovering the liquid refrigerant from the liquid refrigerant air conditioner to the second tank.

The heat exchanger is installed in an opening of the fan shroud in which the blowing fan is installed, and the heat exchanger is formed in a panel type to be opened and closed by a hinge part provided at one side of the opening of the fan shroud.

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

In an embodiment of the present invention, ammonia, a fluorinated hydrocarbon chloride refrigerant (freon), an azeotropic mixed refrigerant, methyl chloride, and the like, which are generally used in a refrigerating cycle, are all referred to as a "refrigerant". In addition, it is to be applied to the refrigeration cycle using a material that is easy for the public to handle, such as water, alcohol, antifreeze, etc. without adversely affecting the environment, which is referred to as "liquid refrigerant".

Hybrid liquid air conditioner according to an embodiment of the present invention maximizes the cooling efficiency by using a liquid refrigerant produced by the refrigeration cycle, and a liquid refrigerant generated by the refrigerant cycle harmless to the environment at low temperature using a conventional refrigerant. Is configured to.

1 is a configuration diagram according to an embodiment of the present invention, as shown in Figure 1, the instantaneous cooler 100 to produce a liquid refrigerant within a short time, and the liquid refrigerant produced in the instantaneous cooler 100 It consists of a liquid refrigerant air conditioner to lower the temperature of the room using.

2 is a configuration diagram of an instantaneous cooler applied to an embodiment of the present invention, the instantaneous cooler 100 is a compressor 110, a condenser 120 for liquefying gas compressed at high temperature and high pressure in the compressor, and An expansion valve 130 for expanding the liquid condensed in the condenser to a state of low temperature and low pressure, and an evaporator 140 for heat-exchanging the target material passing by the refrigerant gas supplied from the expansion valve. At this time, the evaporator is used for the instant cooling evaporator 140 to cool the target material passing within a short time.

As shown in FIG. 3, the instantaneous cooling evaporator 140 continuously generates a liquid refrigerant within a short time, and a refrigerant case 142 through which the refrigerant passes, and inside the refrigerant case 142. It is installed to include a liquid refrigerant passage 144 that is heat exchanged with the refrigerant while the liquid refrigerant passes through.

In the internal space of the refrigerant case 142, all of the remaining spaces except the space of the liquid refrigerant passage 144 may be used as the flow path of the refrigerant. However, if the flow path volume of the coolant is excessively large, for example, when the ratio exceeds 1: 6, the coolant case 142 may be inflated due to excessive coolant pressure, which may cause damage.

In some cases, the refrigerant passage and the liquid refrigerant passage 144 may be formed in a mutual double tube type. However, this double tube type has difficulties in actual installation.

Therefore, in the embodiment of the present invention, as shown in Figure 3, it is preferable that the pipe forming the liquid refrigerant passage 144 as a whole corrugated pipe type to bend freely the portion where the tube is bent. Alternatively, only the portion bent at both ends of the tube may be formed into a corrugated tube.

In addition, although not shown in the drawings, it is preferable to maximize the heat exchange area by providing a heat exchange fin on the outer circumferential surface of the tube constituting the liquid refrigerant flow passage, or by using a spiral tube when the tube is applied.

In addition, in one embodiment of the present invention, connection passages 310 and 320 are provided between the instantaneous cooler 100 and the liquid refrigerant air conditioner 200.

In this case, a first tank 210 for receiving the liquid refrigerant generated by the instantaneous cooler 100 is installed in the connection passage 310 of the connection passage. And the first tank 210 is connected to the heat exchanger 220 for heat-exchanging the indoor air using a liquid refrigerant in a low temperature state. In addition, a second tank 230 which is connected between the heat exchanger 220 and the instantaneous cooler 100 by a connection flow path 320, and recovers the liquid refrigerant in a high-temperature state exchanged to the connection flow path 320. Is installed.

As shown in FIG. 4, the heat exchanger 220 is provided with a blowing fan 240 for discharging indoor air that is heat-exchanged into the room. The heat exchanger 220 is installed in the opening 244 of the fan shroud 242 in which the blowing fan 240 is installed, and the heat exchanger 220 is formed in a panel type so that one side of the fan shroud opens. It is installed to be opened and closed by the hinge portion 246 provided in the.

A first pump 250 is installed between the first tank 210 and the heat exchanger 220, and a second pump 260 is installed between the heat exchanger 220 and the second tank 230. do.

The operation of the hybrid air conditioner according to an embodiment of the present invention configured as described above will be described.

The liquid refrigerant generated in the instantaneous cooler 100 is collected into the first tank 210. The liquid refrigerant collected into the first tank 210 is supplied to a heat exchanger 220 installed in a closed space required by the connection passage 310. In this case, the length of the connection flow paths 310 may be increased as necessary. This is because a flexible PVC pipe is used as a material of the connection flow path 310 without using a conventional copper pipe. Therefore, the installation of the connection pipe is easy and the installation cost is low. In addition, the liquid refrigerant used in the present invention, even if water, alcohol, antifreeze, such as water leakage is prevented environmental pollution, and because it is not the copper pipe during the installation process to eliminate welding can prevent fire.

The low-temperature liquid refrigerant supplied to the heat exchanger 220 is discharged into the room by the blowing fan 240 in the present invention, thereby cooling the air in the sealed indoor space.

The liquid refrigerant in the high temperature state that is heat-exchanged while passing through the heat exchanger 220 is recovered to the second tank 230 through the connection flow path 320. When the continuous cooling operation is performed, the instantaneous cooler 100 is circulated to cool the liquid refrigerant again.

In addition, only one tank may be installed without the first and second tanks 210 and 230. In this case, one circulation motor of liquid refrigerant is used, and the liquid refrigerant is supplied from the tank to the instantaneous cooling evaporator by the circulation motor, and the liquid refrigerant passing through the evaporator is immediately transferred to a heat exchanger installed in the room, and an air blower is attached to the heat exchanger. Cold air is supplied by the fan, and the heat-exchanged liquid refrigerant is returned to the tank. This structure has the advantage of simplifying the structure and reducing the manufacturing cost because only one liquid refrigerant tank and the pump is a circulation motor.

In the above-described embodiment of the present invention, the air conditioner mainly performs cooling, but as shown in FIG. 5, when the instant chiller 400 is provided, such as a hot water boiler, the entire system provides cooling and heating. It can be performed selectively. This can be logically described as described in the above-described embodiment. At this time, the configuration requirements may be satisfied by a heat exchanger, a blowing fan, first and second tanks, a connection flow path, and the like.

As described above, the hybrid air conditioner according to the present invention is suitable for a facility or a place requiring a large air conditioner for efficiently performing the cooling effect by a general small air conditioner. That is, in order to maintain a space for massing a large number of animals, such as a barn, or for cultivating a large amount of plants, such as a horticultural farm or a flower complex, a general small air conditioner has a great difficulty in management as well as cost.

For example, in the case of livestock farms, various kinds of volatile organic compounds are generated due to the manure generation of the animals raised in the herd. Therefore, with the generation of corrosive gas such as ammonia, copper pipes or metallic pipes used in general air-conditioning devices cannot secure corrosion resistance, thereby reducing the economics of the product. In addition, there is a problem that requires a skilled technician that can solve all the problems that may occur in the process of circulating the high-pressure refrigerant to the indoor unit, because it uses a highly flammable floor in general to connect the indoor, outdoor air The copper pipe is always exposed from the danger of fire during welding work.

It can be said that the effect of this invention can solve such various problems simultaneously. First, since the liquid refrigerant circulates between the indoor unit and the outdoor unit, the high pressure gas is excluded. Second, there is no risk of fire in the installation by eliminating welding because the connection path between the indoor unit and the outdoor unit is easy to install and uses low-cost PVC or accelerator pipe. Third, labor costs can be reduced because there is no need to arrange a separate skilled technician for maintenance of the facility. Fourth, it is possible to large-capacity at a low cost and use a liquid refrigerant having a high specific heat, thereby minimizing heat loss on the circulation path, thereby maximizing heat exchange efficiency. And in summer, there is an advantage that the dehumidification effect is excellent by the heat exchanger according to the present invention.

In addition, in the case of horticultural farm or flower farm, it is difficult to manage the cold or cold period. This is a problem related to energy management because it may adversely affect plant growth, especially when the air generated in the indoor unit is in direct contact with the plant. Although not described in detail in the present invention, it is possible to solve these problems by controlling the temperature of the discharged air or by switching to the discharge direction, and at the same time, it is possible to solve problems similar to those in the barn described above. Will be.
