Description

Low pollution cooling and heating boiler using waste heat of air conditioner

The present invention relates to a heating and cooling boiler that can achieve both heating and cooling, and more particularly, by using waste heat generated in the air conditioner when using the summer air conditioner as a heat source of the boiler by using waste heat of the air conditioner that can use hot water without boiler operation. It is about low pollution cooling and heating boiler.

In general, air conditioners are used to feel cool by sending cold air to the atmosphere when the temperature rises during summer due to an increase in the air temperature. Boilers are used to achieve bath or dish washing.

Up to now, all air-conditioning equipments such as houses and buildings have separate air conditioners and indoor units, separate boiler installations, separate boiler installations and separate chillers (chillers) to provide warm or cold air. Air-conditioning and cooling and hot water was provided by supplying cold and hot water to a fan coil unit or a unit heater.

In addition, the air-conditioning method for installing an outdoor unit equipped with a cooling compressor and a boiler, or a device for forming air-conditioning by using a chiller (chiller) and a boiler together in the cooling season, waste heat discharged from the air conditioning unit on the rooftop or outside the building. Installed outdoor units or cooling towers.

That is, as shown in FIG. 6, the compressor 1 compresses the refrigerant gas at high temperature and high pressure, and the fan coil 2 connected to the compressor 1 to condense the high temperature high pressure refrigerant gas by the blowing of the fan motor 4. Outdoor unit (condenser) (3) having a built-in outdoor unit is installed in the outdoor unit, and an indoor unit (5) connected to the outdoor unit (3) to form a cold air is installed indoors so that the high temperature high pressure refrigerant gas generated in the condenser (1) is an outdoor unit. After condensing through the (3) and sent to the indoor unit to blow the air temperature to lower the room temperature to achieve cooling, the evaporated refrigerant gas is sent to the compressor (1) to repeat the above action to achieve the use of the air conditioner, but the outdoor unit ( 3) Since the condenser is installed on the veranda outdoors, i.e. in a residential area such as a rooftop or an apartment, the ambient temperature in the condensation process (a process of cooling the high-temperature and high-pressure refrigerant gas) is rapidly increased. And thereby increase the degree, it was also results in discomfort due to noise life, when installed in a veranda had a drawback that the feel uncomfortable noise and traffic.

In addition, when the outdoor unit (3) or cooling tower is attached to the building roof or outdoors during the summer period required for cooling, it is difficult to secure space in the place of attachment and due to the excessive weight of the outdoor unit (3) to be attached, Not only is it difficult to attach in space, but there are also risks of accidents. Until now, air conditioners installed on roofs or exterior walls of various buildings, buildings, and houses have become the main culprit of urban pollution more than automobile noise pollution.

These problems will emerge as a big problem of urban pollution unless there is a special alternative, and the demand for air conditioners will increase exponentially so that life can improve with the arrival of $ 10,000 national income. Moreover, in the narrow spaces such as hot winds and noises produced by the outdoor unit of the air conditioner installed in the building, restaurants and hospitality shops along the busy roads around July ~ Aug. The noise and hot wind from installed outdoor units will be the biggest problem of summer urban pollution.

On the other hand, the boiler which is conventionally used for heating or to obtain hot water is installed burner (9) at the bottom of the heat exchanger (8) in which the hot water supply coil (7) is arranged in the water chamber (6) as shown in FIG. By operating the burner 9 so that the hot water is heated by the hot water supply coil 7 which heat-exchanges with the hot water generated by the temperature of the water chamber 6 to be heated, or the hot water is used to circulate the hot water in the water chamber to achieve heating. However, this is because it is limited only to the function of obtaining hot water by heating or hot water in winter, it was to use a separate air conditioner for cooling in summer.

Therefore, there is a burden of purchasing cost because the air conditioners and heaters are separately purchased and used, especially when using separate air conditioners at the same time, there is a burden of fuel and electric charges, and inconvenience of work and unnecessary labor due to installation space, construction and piping. Of course, there was a drawback to secure the installation space.

In addition, as shown in Japanese Patent Laid-Open Publication No. 7-318114, a first circulation path in which a phase change fluid is sealed by sequentially connecting a compressor, a condenser, and an evaporator, water, or an antifreeze, in which a fluid conveying part, a heating part, and a heat radiating part are sequentially piped. And a fluid power recovery section for recovering liquid energy by using a pressure difference at the time of depressurization from a high pressure liquid to a low pressure liquid installed between the condenser and the evaporator of the second circulation path and the first circulation path in which the first circulation path is sealed. Although it is composed of a fluid pump that connects the conveying unit to transmit power, it is almost impossible to heat by using the heat pump with the lowest efficiency among the components that use electricity, and the evaporator (cold wind) is installed outside. It is operated in winter when the weather is below freezing and the evaporator freezes, making it impossible to perform its function. . In addition, the problem of the existing air conditioner is not improved because the outdoor unit of the existing air conditioner is installed outside, and the fuel used for heating includes diesel, oil, gas, and electricity, but the most expensive electricity is used among the most commonly used fuels. In addition, the use of heat pumps with the lowest efficiency among electrical products is hardly feasible, and it is not a heating device using waste heat, and the problems of noise pollution and outdoor unit installation during cooling in summer cannot be solved.

Accordingly, the present invention has been made to improve the problems of the prior art due to the noise and pollution caused by the use of such a cooler, the object of the present invention is to eliminate the noise and hot air discharge of the outdoor unit that is the main cause of pollution, and to the atmosphere By absorbing the waste heat discharged and using it as a heat source for boilers that require waste heat, it enables cooling and heating with low fuel cost in cities and rural areas, and installs with low material cost in a narrow place. It is to provide a low-pollution cooling and heating boiler using waste heat of the air conditioner to achieve economical and practical use.

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

1 is a schematic overall configuration of the air conditioner according to the present invention, the present invention is the first and second cooling means 100, 102, 106, 108, the supply means 104 and the support concealed It consists of a boiler casing 250 to form an outer shell.

The primary cooling means (100) is formed as a heat exchanger (12) in which a primary condenser (24) into which hot and high pressure gas is pumped by a compressor (16) used in a known air conditioner.

The primary condenser 24 is wound by a predetermined interval from the lower end of the hot water supply coil 400 formed on the heat exchanger 12 to the inner wall to form a heat exchange, and inside the air rises from the bottom to form another heat exchange 500 is provided.

In the lower portion of the hot water tank 22, a secondary condenser 26 provided by a fan coil 26 zigzag-connected with the primary condenser 24 and two to cool the secondary condenser 26 as outside air are provided. Differential cooling means 102 is formed.

And the third cooling means 106 to compensate for the insufficient cooling state through the first and second cooling means (100, 102) is a fan motor 302 on the top of the heat exchanger (12) and hot water tank (22) Is formed of a blower (200, 200a) consisting of an exhaust hood (300, 300a) for transmitting the sucked air to the outside.

The tertiary cooling means 106 has an exhaust hood (302) driven by the motor fan 302 as the exhaust fans 200 and 200a operate due to insufficient cooling by the primary and secondary cooling means 100 and 102. The outside air is sucked into the air 300 and 300a, and the outside air is raised from the lower part of the combustion device 10 or from the lower part of the fan coil 26, guided to the pipe 500, and ascended and discharged to the outside. Hot water of the tank 22 is heat-exchanged and is formed to further increase the cold state.

The heat exchanger 12 disposed at the lower end of the hot water tank 22 is provided with a water chamber 502 for performing heat exchange by the combustion device 10 combusting at the lower end of the boiler when the cooler is not used in winter. 14) Only hot water can be obtained by operating separately.

The supply means 104 is the hot water generated in the heat exchanger 12 is raised to the hot water tank 22 through the pipe 30 to obtain hot water without the boiler 14 operating and the hot water supply coil 400 therein It is arranged to obtain hot water supply.

In addition, the heat exchanger 12 is attached to one side of the water discharge valve 202 for discharging the internal warm water of the heat exchanger 12, the fourth cooling means 108 is formed.

The fourth cooling means 108 simultaneously with the continuous use of the air conditioner while being sent from the hot water heat exchanger 12 generated by the outdoor unit 20 arranged in the heat exchanger 12 to the hot water tank 22. In the case of maintaining the cooling state in order to continuously create the refrigerant gas, the high pressure and high temperature refrigerant gas supplied to the primary condenser 24 is increased due to the temperature rise of the heat exchanger 12 and the hot water tank 22. If the heat exchange efficiency decreases even though the heat exchange is performed by the secondary cooling means, the water of the heat exchanger 12 is discharged to the discharge valve 202 to discharge the hot water in the chamber of the heat exchanger 12 to reduce the temperature, thereby ensuring a safe heat exchange. It is formed to achieve.

The hot water tank 22 and the heat exchanger 12 disposed in the boiler casing 250 may be manufactured by changing the positions of the upper and lower ends about the diaphragm 608 disposed in the center of the boiler casing 250. Compressor 16 may also be arranged on the diaphragm 608 or at the bottom to obtain the same performance and effect, and the present invention does not limit the arrangement.

In addition, the hot water tank 22 is provided so that the air circulation passage 42 is provided outside the storage tank 40 is built to circulate the outside air.

And installed in the space provided on the upper end of the storage tank 40 built in the hot water tank 22 to install an air blower 44 to form a blow air to blow the ambient air of the storage tank 40 It is composed.

A plurality of air inlet holes 60 are provided at the bottom of the body of the boiler casing 250 to allow outside air to flow therein so that the outside air flows into the space 605 formed inside the boiler 14 so that the cooling operation is smoothly performed. .

In the upper end of the heat exchanger 12, a communication 606 for discharging the combustion gas combusted by the combustion device 10 is installed to protrude toward the upper end of the boiler casing 250.

In addition, a compressor 16 is installed on the inner bottom of the boiler casing 250 or the bottom of the diaphragm 608 to compress the refrigerant gas at high temperature and high pressure, and form an outdoor unit 20 in which the compressed high temperature high pressure refrigerant is transferred and condensed. .

According to the present invention having the above configuration, hot water is obtained from waste heat of the outdoor unit (condenser) 20 in which high heat is generated by using a cooler without operating the boiler 14 in summer, as shown in FIG. As can be, by operating the compressor 16 installed in the diaphragm 608 formed inside the boiler casing 250 to compress the refrigerant gas to a high pressure, the high temperature and high pressure gas is moved along the conduit to the inside of the heat exchanger 12 It is sent to the outdoor unit 20 provided with the installed primary condenser 24.

The high temperature and high pressure gas transferred to the outdoor unit 20 thus obtains condensed refrigerant gas required for cooling at the same time as the hot water without heat of the combustion device 10 while performing heat exchange in the water chamber in the heat exchanger 12, the primary condenser The high temperature and high pressure gas, which is primary condensed by 24, is sent to the secondary condenser 28 connected to the primary condenser 24 and installed at the lower end of the hot water tank 22, so that the secondary cooling means 102 The secondary condenser 28, which is composed of the secondary cooling means 102, is made of a fan coil 26 wound in a zigzag to achieve cooling by air cooling, thereby providing refrigerant gas from the compressor 16.

The refrigerant gas is sent to the primary condenser 24 provided in a coil shape in the storage tank 40 of the outdoor unit 20 to exchange heat with water and water cooling of the storage tank 40, and then the primary condenser 24. ) Is sent to the secondary condenser 28 provided with a fan coil 26 disposed in the lower space of the storage tank 40 is air-cooled by the space of the space to be condensed into secondary condensate to the interior of the residential area It is sent to a normal indoor unit (not shown) installed to achieve cooling by cold wind, condensing gas by air cooling and water cooling, and good air conditioner in summer to make comfortable life by cooling, and to install outdoor unit separately. It is not possible to install in a narrow place, and at the same time, it achieves cooling that saves material cost and construction cost according to piping work.

On the other hand, the hot water heat exchanged by the primary condenser 24 is sent to the boiler 14 or the hot water tank 22 through the pipe 30 as shown in Figs. 1 to 3 without having to operate the combustion device 10. Obtained hot water is discharged through the heating outlet 700 attached to one side of the heat exchanger 12 to achieve heating, and the cooling water cooled to form the heating inlet 702 attached to the bottom of the heat exchanger 12 Since it is introduced into the heat exchanger (12) through it to achieve the heating by hot water.

If the air conditioner is not to be used or in winter, the combustion device 10 is operated to heat the heat exchanger 12 by combustion to obtain hot water to obtain hot water or to obtain hot water for heating and to obtain hot water and heating. Phosphorus boiler operation can be achieved.

In addition, when there is no heating in the summer or the use of hot water is low, the storage chamber of the storage tank 40 is in a high temperature state in the lower space of the primary condenser 24 and the storage tank 40 in the storage tank 40. When the cooling efficiency of the air and water cooling of the secondary condenser 28 made of the installed fan coil 26 is lowered and the heating efficiency is lowered, the storage tank 40 is installed inside the hot water tank 22 to the outside. The outside air is naturally circulated by the provided air circulation passage 42 to achieve natural cooling, but when the effect is less than expected, the blower 44 installed at the top of the storage tank 40 is operated to operate. When the air in the space 50 in the boiler 14 is exhausted from the lower end of the storage tank 40 to the upper to cool the storage tank 40, thereby suppressing the temperature rise. If the cooling efficiency is lowered despite the precautions, the blower 44 installed in the cooling device 10 of the boiler 14 is operated to blow air from the combustion chamber to the communication 106 through the flue. 12 is cooled and supplied from the storage tank 40 to achieve safe cooling.

Meanwhile, a diaphragm 108 is installed at the inner center of the boiler 14, and a hot water tank 22 is installed at a lower portion thereof, and a boiler 14 is installed at the bottom thereof or vice versa. In this invention, the position can be freely changed according to design or use without being limited thereto.

In addition, a plurality of inflow holes 60 are provided at the lower end of the body of the boiler 14 to naturally flow outside air to always supply air to the space 50 provided in the boiler 14 so that the boiler 14 Of course, the hot water tank 22 is always cooled to obtain a high efficiency of the outdoor unit 20, and when the combustion device 10 is operated, a sufficient amount of oxygen necessary for combustion is provided to increase the combustion efficiency.
