Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hybrid cooling and heating system having a complex heat source,

The present invention relates to a hybrid air-conditioning system having a complex heat source, and more particularly, to a hybrid air-conditioning system having a composite heat source, and more particularly to a hybrid air- The present invention relates to a hybrid heating and cooling system having a composite heat source for maximizing the temperature drop of the water storage tank heat source by selectively supplying the heat.

The most common energy sources are fossil fuels such as coal, oil, and natural gas, or nuclear fuel. These fossil fuels pollute the environment due to various pollutants generated in the combustion process, and nuclear fuel has harmful substances such as water pollution and radioactivity, and these energy sources have a limited amount of reserves.

In recent years, technologies for the development of alternative energy have been actively promoted. Among the alternative energy, studies on natural energy such as wind power, solar heat, and geothermal energy have been carried out for a long time, and a cooling and heating apparatus using the same has been installed .

While the above natural energy has the advantage of obtaining infinite energy without having little impact on environmental pollution and climate change, it is necessary to increase the density and convert it into usable form due to the extremely low energy density, It is the key point of development.

One of the natural energy technologies is known as a heat pump system for cooling and heating by using geothermal heat as a heat source. A heat pump system using geothermal heat is a technology that uses a heat pump as a heat source by installing a heat exchanger to recover heat from the ground at a temperature of 13 to 50 ° C or to discharge heat to the ground.

As described above, the heat pump system using the geothermal energy is the most energy efficient technology among the heating and cooling technologies, and therefore it is a necessary technology in a situation where the energy resources are insufficient and the energy cost is high.

However, the above-mentioned system must not only provide geological characteristics at the time of installation, but also must secure a site space of 1.6 times as much as a specific space to be covered, thereby increasing a long-term construction period and cost.

In order to solve the above problem, Korean Patent No. 10-1190260 (Oct. 10, 2012) discloses a compressor for compressing and discharging refrigerant; A heat exchanger connected to the compressor and the first refrigerant pipe; A receiver connected to the heat exchanger and the second refrigerant pipe to store the refrigerant; A water tank in which the receiver is housed; A water heat exchanger disposed in the water tank; A hot water tank connected to the heat exchanger through a first hot water circulation pipe; A load side heat exchange unit connected to the water tank through a cold water circulation pipe and connected to the hot water tank through a second hot water circulation pipe; And a condensation heat removing unit connected to the heat exchanger through a circulation pipe for removing condensation heat to remove condensation heat of the refrigerant.

The hybrid cooling and heating system can perform cooling and heating of a specific space through a single flow of refrigerant, can be easily installed in a relatively small space, reduces installation cost, recovers the remaining heat on the load side, But also the following problems.

That is, the above system stores the remaining heat of the specific space load side (the indoor energy of the glasshouse or the vinyl house in the water tank in the daytime, and the solar power facility in the case of the building) .

However, in the winter season, when the weather does not rise for a long time due to worsening of the weather, the temperature of the water heat source of the water tank is severely lowered because the storage water is not stored in the water tank during the daytime. In such a case, the temperature of the house should be forcibly raised by driving a separate heating system, but there is a problem that the heating cost is high.

Therefore, the conventional technology has a problem that the temperature of the water tank is suddenly dropped when the solution does not float for a long period of time, which has a serious effect on the growth of the plant.

Korean Patent No. 10-1190260 (registered on May 10, 2012.) Korean Patent Laid-Open No. 10-2012-0088106 (public date 2012.08.08.)

As shown in FIG. 1, the hybrid heating and cooling system including the complex heat source of the present invention includes a water storage tank 10 in which a water heat source is stored; A heat pump (20) connected to the submerged coil pipe (23) through which the refrigerant circulated in the water storage tank (10) circulates and compresses and discharges the refrigerant; A hot water tank 30 connected to the first pipe 31 so that heat medium is circulated through the heat pump 20 to be heat-exchanged, and a heat medium having heat exchange is stored; A first pump (32) installed on a channel of the first pipe (31) for pumping a heating medium at a normal temperature and supplying the heated heating medium to the hot water tank (30); A first heat exchanger (40) connected to the second pipe (41) so that heat medium in the hot water tank (30) circulates and exchanges heat therein; A second pump (43) installed on a channel of the second pipe (41) to circulate the heating medium of the hot water tank (30) through the first heat exchanger (40); A load side indoor unit (50) connected to the third pipe (51) for heat exchange with the heating medium in the specific space circulating through the first heat exchanger (40) and cooling / heating the specific space; A first intermittent valve (53) and a second intermittent valve (55) installed on the pipeline of the third pipe (51) for interrupting the flow of the heat medium in the load side indoor unit (50); A third pump (57) installed on a channel of the third pipe (51) to circulate the heating medium of the load side indoor unit (50) through the first heat exchanger (40); A circulation pipe (60) connecting the third pipe (51) and the water storage tank (10) so that the heating medium of the load side indoor unit (50) circulates through the water storage tank (10); A third intermittent valve and a fourth intermittent valve, respectively installed on the conduit of the circulation conduit, for interrupting the flow of the heat medium circulating through the circulation conduit; And the water storage tank (10), and when the temperature of the water heat source of the water storage tank (10) plunges due to the environmental factor not being stored in the water storage tank (10) And an auxiliary heat source for delaying the temperature so that the temperature decrease is maximally extended.

Prior to the description, the specific space in which the system of the present invention is installed refers to a glasshouse or a greenhouse or a variety of buildings in which four-seasons plants are grown. For example, .

The first, second and third heat exchangers described later are preferably plate heat exchangers, and the kind of the heat exchanger is not limited.

The hybrid heating and cooling system equipped with the composite heat source of the present invention is installed in a house (a greenhouse or a glasshouse) to cool and heat the inside of the house.

In the water storage tank 10, a space of a predetermined size capable of storing a water heat source (water) is formed therein, and a predetermined amount of water heat sources are stored therein.

At this time, it is preferable that the water storage tank 10 is buried in the ground, so that the water storage tank 10 is kept stable from the external impact to prevent the water storage source from being leaked.

On the other hand, when the water storage tank 10 is installed in a building, it is preferable that the water storage tank 10 is buried under a specified location.

The heat pump 20 is connected to the submerged coil pipe 23 through which the refrigerant circulated inside the water storage tank 10 circulates and compresses and discharges the refrigerant. At this time, the portion of the submerged coil pipe 23 disposed in the water tank 10 is heat-exchanged with the water heat source inside the water storage tank 10 by driving the heat pump 20, thereby raising the temperature of the water heat source.

Here, the shape of the portion of the submerged coil tube 23 disposed in the water tank 10 is preferably formed in a coil shape so as to exchange heat with the hydrothermal source in a larger area.

Since the principle of the heat pump 20 is a general matter, a detailed description will be omitted.

The hot water tank 30 is connected to the first pipe 31 so that the heat medium in the hot water tank 30 circulates through the heat pump 20 and is heat-exchanged. And a predetermined size in which a storage space is formed is maintained therein.

In this case, the first pipe 31 is formed as a pair so that the heating medium of the hot water tank 30 can circulate.

The first pump 32 is installed on one of the pipelines of the pair of first pipes 31 and pumps the heating medium at room temperature heated by the driving of the heat pump 20 to the hot water tank 30 .

The first heat exchanger (40) is connected to the second pipe (41) so that the heating medium of the hot water tank (30) circulates and exchanges heat therein. That is, the second pipe 41 is connected to one side of the first heat exchanger 40, and in this state, the heating medium is circulated in the first heat exchanger 40 through the second pipe 41, And heat exchange with the heat medium of the indoor unit 50 is performed.

In this case, it is needless to say that the second pipe 41 is formed in a pair so that the heating medium can circulate in the first heat exchanger 40.

The second pump 43 is installed on one of the pipelines of the pair of second pipes 41 to forcibly pump the heating medium in the hot water tank 30 to circulate the first heat exchanger 40 .

The load side indoor unit 50 is connected to the third pipe 51 so that the heating medium of the house (green house or glass greenhouse), which is a specific space, circulates through the first heat exchanger 40 and exchanges heat, thereby cooling and heating the house.

At this time, the third pipe 51 is connected to the other side of the first heat exchanger 40, and the heating medium of the load-side indoor unit 50 circulates through the third pipe 51 connected to the first heat exchanger 40 Heat exchange occurs.

In this case, the third pipe 51 is formed as a pair so that the heating medium can circulate in the first heat exchanger 40.

A first intermittent valve 53 and a second intermittent valve 55 are provided on the piping of the pair of third pipes 51. The first intermittent valve 53 and the second intermittent valve 55 interrupts the flow (flow) of the heating medium of the load side indoor unit 50.

This is because heat storage is made in the water storage tank 10 by using the heating medium of the load side indoor unit 50 through the circulation pipe 60 to be described later or when the cooling of the house is performed through the water heat source of the water storage tank 10 50 from flowing to the first heat exchanger (40).

The third pump 57 is installed on one of the pipelines of the pair of third pipes 51 so that the heating medium of the load side indoor unit 50 is forcedly pumped to circulate the inside of the first heat exchanger 40 .

Accordingly, the load-side indoor unit 50 allows the heat exchanging heat medium to flow through the room of the house (greenhouse or glass greenhouse) by the first heat exchanger 40 while heating the room of the house when the heat medium is high, Cool the house.

At this time, the load side indoor unit 50 may be installed inside the house for cooling and heating the house.

The circulation pipe 60 connects the third pipe 51 and the water storage tank 10 so that the heating medium of the load side indoor unit 50 circulates through the water storage tank 10.

That is, the circulation pipe 60 is formed of a pair so that the heating medium of the load-side indoor unit 50 and the hydrothermal source of the water storage tank 10 can be circulated to each other to directly connect the third pipe 51 and the water storage tank 10 The heat storage of the water storage tank 10 is circulated through the circulation of the heating medium in the load side indoor unit 50 and the water heat source of the water storage tank 10 is circulated during the cooling of the house to the load side indoor unit 50.

At this time, a third intermittent backbone and a fourth intermittent valve 63 are provided on the piping of the pair of circulating pipes 60, respectively, and the third intermittent backbone and the fourth intermittent valve 63 are connected to the circulating pipe 60 Thereby blocking the circulation of the heat medium.

In this case, when the house is heated, the heat medium circulating through the load-side indoor unit 50 is blocked from flowing into the circulation pipe 60.

The auxiliary heat source is connected to the water storage tank 10 through a pipe and is not stored in the water storage tank 10 due to an environmental factor so that when the temperature of the water source of the water storage tank 10 plunges, So that the temperature drop of the water heat source is extended as much as possible by delaying the sudden temperature drop of the water heat source.

In other words, the auxiliary heat source can not be smoothly stored in the water storage tank 10 during the daytime when there is no long-term solution due to deterioration of the weather in the winter season. Therefore, if the weather deterioration continues, So that the temperature of the heat source is gradually decreased without dropping, so that the use period of the heat source is maximally extended.

The auxiliary heat source is preferably driven when the temperature of the water source of the water storage tank 10 falls below a predetermined temperature and the geothermal part 70, the air column part 80 and the water supply part 90 Are preferably set so that they are driven respectively when the temperature of the water heat source reaches the set temperature.

The auxiliary heat sources may be controlled by a separate control unit (not shown).

The auxiliary heat source may be a geothermal part 70 that replenishes a heat source with the water storage tank 10.

The geothermal part 70 includes a perforated plate 71 formed with a plurality of geothermal perforations 72 and a perforated plate 72 connected to the geothermal perforations 72 of the perforated plate 71 to circulate the heat medium of the geothermal perforations 72 A first auxiliary piping 75 connected to the water storage tank 10 and made of a pair for circulating the hydrothermal source of the water storage tank 10, a first auxiliary piping 75 connected to the geothermal piping 73 and the first auxiliary And a second heat exchanger 77 for interconnecting the heat medium of the circulating geothermal heat source and the hydrothermal source to which the pipe 75 is connected.

In this case, when only geothermal heat is used as a heat source, generally, 33 geothermal drilling holes 72 are drilled, but the number of geothermal drilling holes of the geothermal heat source 70 of the present invention is 6 to 8 holes. That is, the heat source is not used mainly as in the prior art but is used as a sub-equation in the event of an emergency.

The geothermal part 70 of the present invention is supplied with only the geothermal heat that can be assisted in case of need, so that no separate management equipment for managing the 33 geothermal perforations 72 is required.

On the other hand, the fourth pump 74 and the fifth pump 74 are arranged on the pipeline of the geothermal piping 73 and the first auxiliary piping 75 so as to circulate the heat medium of the geothermal piping 73 and the hydrothermal source of the water storage tank 10, (76) is preferably provided.

The geothermal unit 70 drives the fourth pump 74 and the fifth pump 76 to cool the heating medium of the geothermal heat pipe 73 and the water storage tank 10 when the water heat source of the water storage tank 10 falls below the set temperature, So that the heat exchange in the second heat exchanger 77 is performed.

The geothermal part 70 is driven until the water heat source has a temperature equal to that of the geothermal heat, and stops driving when the temperature of the water heat source becomes equal to the geothermal temperature.

Meanwhile, the auxiliary heat source may be an air heating unit 80 for supplementing the heat source with the water storage tank 10.

The air heat unit 80 includes an air heat heat pump 81 for generating a heat medium at room temperature by using air and an air heat pipe 83 connected to the air heat heat pump 81 for circulating the heat medium of the air heat heat pump 81 A second auxiliary pipe 85 which is connected to the water storage tank 10 and through which the water heat source of the water storage tank 10 circulates and a second auxiliary pipe 85 which is connected to the air heat pipe 83 and the second auxiliary pipe 85, And a third heat exchanger 87 for mutually exchanging heat between the fruit bank of the water tank 81 and the water heat source of the water storage tank 10.

The sixth pump 84 and the seventh pump 85 are connected to the air heat pipe 83 and the second auxiliary pipe 85 so as to circulate the heat medium of the air heat pipe 83 and the water heat source of the water storage tank 10, (86) is preferably provided.

When the water heat source of the water storage tank 10 falls below a set temperature, the air heat unit 80 drives the sixth pump 84 and the seventh pump 86 to cool the heat medium of the air heat pipe 83 and the water storage tank 10, So that the heat exchange in the third heat exchanger 87 is performed.

The air heaters 80 are driven until the water heat source has the same temperature as that of the air heat, and when the temperature of the water heat source becomes equal to the temperature of the air heat, the driving is stopped.

Meanwhile, the auxiliary heat source may be a water supply unit 90 for instantly securing the temperature of the water heat source when the temperature of the water heat source of the water storage tank 10 drops rapidly.

The water supply unit 90 includes a water supply pipe 91 connected to the water storage tank 10 so that ground water or raw water is supplied to the water storage tank 10 and an eighth water supply pipe 94 installed on the pipe of the water supply pipe 91 for pumping ground water or raw water. A pump 95 and a fifth intermittent valve 93 installed on the channel of the direct water pipe 91 for interrupting the flow of ground water or raw water.

In other words, when the temperature of the water source of the water tank 10 is not stored or the temperature of the water tank 10 drops below 5 degrees even if the heat is accumulated, the water supply unit 90 ensures the instantaneous heat source of the water source of the water storage tank 10 The fifth intermittent valve 93 is opened while the eighth pump 95 is driven to supply the ground water or the raw water to the water storage tank 10 so that the water is drained so that the temperature of the water heat source is raised to a set temperature ).

This is because it is the minimum temperature for driving the heat pump 20 to adjust the temperature of the water source to 5 degrees.

When the temperature of the water heat source reaches the set temperature, the water supply unit 90 stops driving.

On the other hand, in the direct water pipe 91 between the eighth pump 95 and the fifth intermittent valve 93, the ground water or raw water is supplied to the hot water tank 30 when the heat pump 20 is driven according to the user's set cooling And the bypass pipe 97 is provided with a sixth intermittent valve 99 for interrupting the flow of ground water or raw water.

That is, the ground water or raw water is supplied from the direct water pipe 91 to the hot water tank 30 by using the bypass pipe 97.

This is because the user drives the heat pump 20 to lower the temperature of the source of the water source of the water tank 10 during cooling to a certain temperature so that the ground water or the raw water is supplied to the hot water tank 30, 30 from being overheated.

However, in the present invention, low-temperature (5 degrees) ground water or raw water is directly supplied through the water supply unit 90, so that a separate cooling device is installed in order to cool the hot water tank 30 Thereby reducing the inconvenience and the cost associated with the operation.

Hereinafter, the operation of the hybrid air conditioning system including the complex heat source of the present invention will be described with reference to FIGS. 2 to 6. FIG.

FIG. 2 is a system diagram showing a hybrid heating / cooling system having a complex heat source according to the present invention performing heating.

The flow of heating is shown by an arrow.

First, when the heat pump 20 is driven, the heating medium in the hot water tank 30 is circulated through the first pipe 31 and passes through the heat pump 20. In the process of heat exchange with the refrigerant, And is supplied to the hot water tank 30 again. The above process is carried out continuously.

At this time, circulation of the heating medium is performed by driving the first pump 32. [

On the other hand, the refrigerant of the heat pump 20, which has exchanged heat with the heat medium of the hot water tank 30, is circulated to the side of the water storage tank 10 through the submerged coil pipe 23 and absorbs heat from the hydrothermal source through evaporation. The temperature of the water source of the water storage tank 10 is cooled.

The heating medium of the warmed hot water tank 30 is circulated through the second pipe 41 and flows inside the first heat exchanger 40. At this time, the second pump 43 is in an ON state.

The heating medium of the load side indoor unit 50 is circulated through the third pipe 51 and flows inside the first heat exchanger 40. In this process, the heating medium of the load side indoor unit 50 flows into the hot water tank 30, Exchanged with the heat medium of the heat exchanger.

The heating medium of the heat-exchanged load-side indoor unit 50 flows through a separate pipe installed inside the house, and the house is heated.

At this time, the third pump 57 is in an ON state, and the first intermittent valve 53 and the second intermittent valve 55 of the third pipe 51 are in a state in which the heating medium of the load- It is open to do.

On the other hand, in the case where the accumulation of the water storage tank 10 is not smoothly performed during the daytime due to deterioration of the weather during heating, if the weather deterioration continues for 2 to 3 days, the water storage tank 10 The geothermal part 70 and the air heating part 80 are driven.

3 is a schematic diagram showing a state in which the geothermal part 70 and the air heat part 80 of the auxiliary heat source are driven.

The control device drives the geothermal part 70 and the air heating part 80 when the temperature of the water source of the water storage tank 10 is suddenly dropped to 15 degrees or less by a control device (not shown).

Here, the temperature range of the geothermal heat is 13 to 15 degrees, and the temperature range of the air heat is 14 degrees. Therefore, when the temperature of the water source drops to 15 degrees or less, the control is performed by the control device.

If the temperature of the water heat source falls to 15 degrees or less in the evening, since the temperature of the outside air is relatively low, only the geothermal part 70 is driven without driving the air heating part 80. However, The temperature of the hydrothermal source remote from the geothermal part 70 and the air heat part 80 is rapidly maintained to 15 degrees.

The geothermal part 70 is driven by driving the fourth pump 74 so that the heat medium of the geothermal perforations 72 is circulated through the geothermal heat pipe 73 connected to the geothermal perforations 72.

In this case, the heat medium of the geothermal perforation 72 flows through the second heat exchanger 77 while circulating through the geothermal pipe 73.

At the same time, the fifth pump (76) is driven to circulate the water heat source of the water storage tank (10) through the first auxiliary pipe (75) connected to the water storage tank (10).

In the circulation process, the water heat source of the water storage tank 10 is heat-exchanged with the heat medium of the geothermal perforation 72 in the second heat exchanger 77 and gradually increases in temperature. The temperature of the water source is continuously increased until it reaches 15 degrees.

The air column portion 80 is driven by driving the sixth pump 84 so that the heating medium of the air heat pump 81 is circulated to the air heat pipe 83 while passing through the third heat exchanger 87.

At the same time, the seventh pump 86 is driven to pass through the third heat exchanger 87 while circulating the water heat source of the water storage tank 10 through the second auxiliary pipe 85.

In this case, the water heat source of the water storage tank 10 is heat exchanged with the heat medium of the air heat pump 81 in the third heat exchanger 87, and the temperature of the water heat is gradually raised to 14 degrees, which is the temperature range of the air heat.

If the temperature of the water heat source reaches 14 degrees, the operation of the air heat part 80 is stopped. If the temperature of the water heat source reaches 14 degrees, the operation of the air heat part 80 is stopped , The geothermal part 70 continues to drive until the temperature of the water heat source reaches 15 degrees.

On the other hand, if the temperature of the heat source of the water storage tank 10 drops to 5 degrees or less as the temperature of the water storage tank 10 is lowered due to the deterioration of the atmospheric deterioration that can not obtain solar heat even within 3 to 5 days, The supply unit 90 is driven.

4 is a systematic diagram showing a state in which the water supply unit 90 of the auxiliary heat source is driven.

When the control unit (not shown) detects that the temperature of the water source of the water storage tank 10 drops to 5 degrees or less, the controller drives the water supply unit 90. [

First, the eighth pump 95 on the direct water pipe 91 is driven to allow ground water or raw water to flow through the direct water pipe 91.

At this time, the fifth intermittent valve 93 maintains the opened state so that the ground water or the raw water flowing through the direct water pipe 91 can be supplied to the water storage tank 10.

In addition, the groundwater or raw water is supplied to the water tank 10 and the drainage of the water heat source is simultaneously performed. This process is continued until the temperature of the water heat source reaches 5 degrees, which is the temperature range of the ground water or raw water.

Next, the process of cooling the house will be described with reference to FIG.

FIG. 5 is a flowchart illustrating a hybrid air-conditioning system having a hybrid heat source according to the present invention performing cooling.

The first intermittent valve 53 and the second intermittent valve 55 of the third pipe 51 are closed so that the heating medium of the load side indoor unit 50 can not be circulated to the third pipe 51.

Thereafter, the third intermittent valve 61 and the fourth intermittent valve 63 are opened and the third pump 57 is driven.

The heat medium of the load side indoor unit 50 is directed to the water storage tank 10 through the third pipe 51 and the water heat source of the water storage tank 10 is directed to the load side indoor unit 50 and the mutual circulation of the heat medium and the hydrothermal source .

Through the above process, the house is cooled by the low-temperature heat medium flowing through the separate piping installed in the house.

In addition, the heat storage of the water storage tank 10 through the circulation of the heating medium in the load side indoor unit 50 can be achieved through the above process.

Next, the process of setting the cooling of the house will be described with reference to FIG.

FIG. 6 is a systematic diagram showing a state in which groundwater or raw water is supplied to the hot water tank 30 during the set cooling in the state of FIG.

The process of cooling the house is the same as that described above, so the explanation will be omitted and only the process according to the set cooling will be described.

When the temperature of the house room is to be further lowered depending on the kinds of plants grown during the cooling of the house, the heat pump 20 is first driven.

The heat medium of the hot water tank 30 is heated to a high temperature by driving the heat pump 20 and the temperature of the heat source of the water tank 10 is lowered by the evaporation of the refrigerant of the heat pump 20.

At this time, while the eighth pump 95 is driven, the groundwater or the raw water is sucked through the water line 91, and at the same time, the fifth intermittent valve 93 is closed and the sixth intermittent valve 99 is opened, And is supplied to the hot water tank (30) by bypassing the pipe (97).

At the same time, in the hot water tank 30, the supply of the ground water or the raw water is performed, and the drainage is performed at the same time, thereby preventing the temperature of the heating medium, which is supplied according to the driving of the heat pump 20, from rising.

As described so far, the hybrid air-conditioning system having the complex heat source of the present invention is capable of cooling and heating a specific space such as a glasshouse, a greenhouse, and a building that require cooling and heating, It is advantageous to extend the temperature of the water storage tank heat source to the maximum by selectively supplying the prepared auxiliary heat source to the water storage tank when the heat storage is not performed in the water storage tank heat source.

In addition, since the heat source is supplemented by using the auxiliary heat source in the extreme environment, there is an advantage that the heating cost is reduced because there is no need to provide a separate heating facility.

In addition, since the auxiliary heat source is provided, there is an advantage that it is always possible to prepare for an extreme situation in case of emergency.

As described above, the hybrid air-conditioning system including the complex heat source of the present invention has been described with reference to the preferred embodiments and the accompanying drawings. However, the present invention is not limited to the technical scope of the invention .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. There is no doubt that it is within.
