Description

Dehumidification combined air conditioner {COLD AND HEAT DEVICE FOR COMBINED DEHUMIDIFY}

The present invention relates to an air conditioner, and more particularly, to maximize the efficiency of the air conditioner that performs the cooling and heating function according to the temperature changes in the room and having an excellent dehumidification power against moisture generated inside the device during operation. It relates to an air conditioner structure.

In general, the air conditioner is to maintain the optimum temperature and humidity according to all climatic conditions and the indoor environment, and a humidifier to maintain the humidity properly, including a cooling device and a heating device that cools or warms the indoor air. And a ventilator for exhausting indoor air to the outside.

Among them, the air conditioner cools the indoor space by using the action of cooling the refrigerant by heat exchange with ambient air when the liquid refrigerant evaporates, and in addition to the cooling action, the dehumidification is performed together. A cooling device having such a function includes a compressor for compressing a refrigerant into a high temperature and high pressure gas form, a heat exchanger for liquefying a compressed high temperature and high pressure refrigerant, an evaporator for evaporating a refrigerant expanded by an expansion valve, and the evaporator. It has a general configuration, such as a blower for forcibly blowing the heat exchanged cooling air to the indoor space that requires cooling.

In addition, the heating device is used to keep the indoor space warm in the cold winter season, and is mainly used in large buildings, such as a small boiler for the home which circulates hot water heated warmly. There is a centralized heating system that supplies heating to the fan coil installed indoors through. In addition, in a place such as an office or a bank, a warm air fan is used to draw indoor air and heat it, and then discharge the air to gradually warm the indoor air.

Such an air conditioner includes a cooling / heating combined air conditioner that can be used as the cooling device and the heating device as described above. The combined air-conditioning and air-conditioning apparatus is capable of cooling and heating by circulating or reverse-circulating the refrigerant flow in a general configuration such as a compressor, a heat exchanger, an evaporator, and a blower as described above.

However, in order to increase the cooling performance, the conventional cooling heat exchanger has a disadvantage of having a relatively low heat exchange efficiency during heating operation because heat exchange is performed while flowing a refrigerant in a single direction.

In addition, the conventional heat exchanger has a disadvantage that has a relatively low heat exchange efficiency during the cooling operation because the heat exchange while the refrigerant flows in both directions in order to increase the heating performance.

In addition, in the case of the air conditioner to which the thermoelectric element having the Peltier effect is applied, there is a problem in that satisfactory heat transfer efficiency is not achieved in using the water-cooled and air-cooled heat radiating methods.

The present invention has been proposed to improve the above problems in the conventional air conditioners, and by using the latent heat material to make the heat exchange can be made more comfortable and effective cooling and heating through the removal of odors and microorganisms generated in the room In addition, it aims to realize an air conditioner with an enhanced indoor dehumidification capability.

The object of the present invention is to provide an evaporator in which heat exchange with air forcedly blown by a blower fan and a refrigerant circulation pipe passing through the evaporator constitutes a circulation cycle. A PCM box in which a phase change material is stored therein is installed for heat exchange; As a means for preheating or precooling a phase change material in the PCM box, a thermoelectric element for radiating heat and cooling from both sides when power is applied, and a thermoelectric for transferring heat generated from one side of the thermoelectric element to a phase change material. The plate is constructed; Inside the PCM box, a heat transfer plate for transferring heat generated from the inside of the thermoelectric element to a phase conversion material, and a heat dissipation block and an outer circumferential surface through which a refrigerant circulation pipe made of heat exchange in an evaporator passes outside the thermoelectric element. A heat dissipation fan is formed along the heat dissipation fins; Dehumidification means for drying and dehumidifying the condensate generated in the evaporator is configured; it can be achieved through a dehumidification combined air-conditioner.

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

First, looking at the overall configuration of the air conditioner according to the present embodiment, as shown in Figs. 1 and 2, the upper portion of the cabinet 10 constituting the main body in an inclined form to the inside of the evaporator 11 of the fin-tube type A blower fan 12 for forced air is installed, and two PCM boxes 13 and 14, in which phase change materials (PCMs) are stored, are mounted at the bottom of the device and at the bottom, respectively. Refrigerant circulation pipe 15 is passed through the boxes 13 and 14, and an air purification filter 16 consisting of a nanophotocatalyst filter and an antibacterial filter and a UV lamp 17 for emitting UV light are provided at a rear end side through which external air is introduced. ) Is installed.

Here, the phase-conversion material (inorganic hydrate, paraffin organic material, clathrate compound, etc.) is further explored by NASA as a part of space development to protect astronauts and devices from the harsh environment of space. It is a new concept material that has the function of absorbing, storing and releasing a large amount of heat. It is also called latent heat storage material. That is, when a pure substance or mixed / chemical substance becomes a solid> liquid> gas (or gas> liquid> solid) state (phase change), it absorbs or releases heat, and the heat generated is called latent heat. It is very effective for absorption, storage and release when the temperature is changed without phase change.

On the other hand, between the two PCM boxes (13, 14), as shown in Figure 3, the heat radiation fins (21, 22) for radiating heat or heat generated around the heat radiating fan 20, both sides when supplying a DC current The thermoelectric elements 23 and 24, which generate cooling and heat generation in the ceramic plate, and the thermoelectric plates 25 and 26, which are charged in the PCM boxes 13 and 14 and preheat or precool the phase change material, are installed in symmetrical shapes. On one side, a dehumidification tank (29) having a multi-layered layer structure in which zeolite and silica gel are stacked in layers by screen nets to dehumidify the condensate guided through the drain pipe 28 from the upper condensate trough 27 on the one side 29 ) Is mounted, the dehumidification tank 29 is communicated to the dry box 30 and the drying tube 32 is provided with a dryer fan 31, the moisture evaporation plate 34 and PTC at the bottom of the dry box (30) (Positive Temperature Coefficient) The drying heater part 33 which consists of elements is comprised. .

In the upper PCM box 13 in which the phase change material is stored therein, a heat transfer plate 41 for transferring heat generated from the thermoelectric element 40 to the phase change material, as shown in FIG. A heat dissipation fan 44 having a heat dissipation fin 43 is formed along the heat dissipation block 42 and the outer circumferential surface, and the refrigerant circulation pipe 15 passing through the PCM boxes 13 and 14 is formed at the end portion B. As described above, the compressed portion 15a formed by pressing the inner diameter into a rectangular shape is formed or the flat portion 15b having a predetermined volume is formed as shown in FIG. 5 to improve the heat exchange efficiency along with the expansion effect of the refrigerant. The dryer fan 31 serves to supply the hot air to the heat radiation fin 43 side during the heating operation.

In the same configuration, the thermoelectric element 40 ', the heat dissipation block 42', the heat dissipation fin 43, the heat dissipation fan 44, and the heat transfer plate (not shown) are also configured in the lower PCM box 14.

On the other hand, the inner wall of the cabinet 10 is made of a photocatalyst coating activated by ultraviolet light, and the wheel is preferably equipped with a gyro sensor for preventing the body from falling.

In the figure, reference numeral 18 denotes a circulation pump for circulating the refrigerant into the refrigerant circulation pipe, and 19 denotes a fan for dehumidification.

As an example, the operation state according to the cooling operation of the present invention cooling and heating unit which constitutes such a configuration will be described.

Heat exchange is performed in the process of forced air blowing inside the cabinet 10 by the rotational force of the blowing fan 12 passes through the evaporator 11, so that cool air is supplied to the room to perform cooling. The low-temperature refrigerant made heat exchange in 11 is made of heat dissipation and cooling in the process of circulating the interior through the circulation pipe (15).

That is, while the pipe 15 passes downward through the heat dissipation blocks 42 and 42 'installed on the extension path, the heat dissipation blocks 42 and 42' through which the low-temperature refrigerant is transferred to the thermoelectric element 40 by the hot plate side. After the heat dissipation is performed by the heat dissipation fans 44 and 44 'together with the cooling, the temperature is lowered while being re-ascended through the lower PCM box 14 and the upper PCM box 13 to circulate the evaporator 11 again. A cooling cycle is achieved.

In particular, in the refrigerant circulation process, in the PCM boxes 13 and 14, the pipe 15 forms a pressurized portion 15a in which the pipe 15 is pressurized flatly so that the space in which the refrigerant flows is reduced, so that the high pressure, Expansion occurs so that the refrigerant is transferred, thereby enabling rapid heat exchange.

On the other hand, the thermoelectric elements (23, 24) provided with the dehumidification container 29 operates during the pre-heating of the late-night time zone, when DC power is applied, both ceramic plates are cooled and generated by the cooling side up and down the PCM box ( The phase change material in 13 and 14 is gradually lowered by the thermoelectric plates 25 and 26.

Along with this, the heat transfer plate 41 inserted into the side surfaces of each PCM box 13 and 14 transmits the cooling heat generated from one surface of the thermoelectric element 40 to efficiently cool the phase change material.

And condensate generated in the evaporator 11 due to the liquefaction during cooling is collected in the condensate drip tray 27, a part of the evaporation and the remaining condensate is guided to the dehumidification tank 29 through the drain pipe 28, and guide The condensed water thus obtained is dissipated by zeolite and silica gel which are provided in layers in the dehumidification container 29.

In addition, as the heat dissipation fan 20 is operated, the heat source generated at the heat generating side of the upper and lower thermoelectric elements 23 and 24 is discharged through the heat dissipation fins 21 to dry the dehumidifying tank 29, and If the amount is large, the drying tube 32 is introduced into the dry box 30. Since the dry box 30 performs automatic temperature control, the condensed water from the moisture evaporation plate 34 is applied by applying a dry heater part 33 made of a variable resistance type PTC element, which is a sensor type that increases or decreases the amount of heat generated according to the ambient temperature. Heat causes evaporation. The PTC element can be used normally at both low and high pressures, and it does not glow red (the electrical resistance wire turns red and emits light), and there is no danger of fire, and oxygen burning in the room does not occur because it does not burn oxygen.

On the other hand, the outside air sucked into the cabinet 10 is purified by the air purification filter 16 formed on the back, the air purification filter 16 is applied to the nano-photocatalyst filter of the ultraviolet lamp 17 When UV light is received, electrons and holes are generated to react with oxygen and water in the air to generate free radicals.

In particular, the nanophotocatalyst filter has a continuous effect unlike general antimicrobial agents that are ineffective over time, and odors and microorganisms generated in a closed space of the room are decomposed by continuous redox reactions on the surface. It removes the cause of odor and removes odor in a small amount. Since it purifies air by the catalytic action, it can be used semi-permanently and thus it is possible to perform pleasant cooling and heating.

As described above, the air conditioner of the present invention stores a phase change material, which is a material that absorbs or releases latent heat as the phase changes depending on the temperature delivered to the medium for heat conversion of the refrigerant, in a plurality of reservoirs (PCM boxes), respectively. Through the pipe, and by applying a thermoelectric element that acts as a Peltier as a device for heat exchange, the cold and hot conversion rate is fast and the temperature can be easily controlled, thereby improving the cooling and heating efficiency.

In addition, by drying the internal condensed water generated by the liquefaction during the evaporation process by applying a PTC element it is possible to improve the reliability of the product by performing the evaporation and dehumidification process.
