The specific structure or functional description presented in the embodiment of the present invention is merely illustrative for the purpose of illustrating an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention can be implemented in various forms. And should not be construed as limited to the embodiments described herein, but should be understood to include all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

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

As shown in FIG. 2, the cooling / heating system for a greenhouse complex complex according to the present invention comprises a triple thermostatic chamber 10, a heat pump 20, and a cooling device 30.

The triple chamber 10 provides the heat pump 20 with the heat energy and the cooling device 30 with the cold heat but without the rapid change of the temperature for a long time and the heat pump 20 and the stable heat source of the cooling device 30, Synchronous.

3, the triple chamber 10 includes a middle-temperature water tank 11, a high-temperature water tank 12 disposed inside the middle-temperature water tank 11, and a high- And a low-temperature water tank 13 arranged so as to be spaced apart from each other by a distance.

The intermediate-temperature water tank 11 is a water tank in which stormwater or groundwater is stored therein as shown in FIG. (R) or groundwater (GW) is fresh water in the temperature range of 10 degrees Celsius higher or lower at room temperature. Therefore, the rain (R) or the ground water (GW) shown in Fig. 7 is an example, and the water may be filled in the inside of the water bath 11. [ Therefore, the intermediate-temperature water tank 11 can be regarded as a water tank filled with fresh water that can be easily obtained in the area where the heating / cooling system according to the present invention is installed. Hereinafter, the fresh water to be filled in the intermediate-temperature water tank 11 will be referred to as a medium-temperature water.

The high-temperature water tank 12 is a water tank which is contained in the middle-temperature water tank 11 and filled with water having a water temperature higher than that of the medium-temperature water. The high-temperature water tank 12 is kept at a high temperature because water heated by receiving the thermal energy is filled in the second condenser 31 constituting the cooling device 30 to be described below.

The low-temperature water tank 13 is a water tank which is contained in the middle-temperature water tank 11, such as the high-temperature water tank 12, and is filled with water having a water temperature lower than that of the medium-temperature water. The low temperature water tank 13 is kept at a low temperature by the second evaporator 33 of the cooling device 30 and the first evaporator 23 of the heat pump 20 to be described below.

However, since the middle-temperature water filled in the middle-temperature water tank 11 is raised to the upper portion of the middle-temperature water tank 11 with relatively high temperature and the middle-temperature water having a relatively low temperature sinks to the lower portion of the middle- The high temperature water in the low temperature water tank 13 is maintained at a high temperature for a longer time than the low temperature water in the low temperature water tank 13 and the low temperature water of the low temperature water tank 13 is maintained at a low temperature for a long time, Is preferred.

Also, depending on the operation state of the cooling / heating system according to the present invention, when the temperature of the hot water in the hot water tank 12 excessively falls, water of a water temperature close to the low temperature water sinks on the bottom of the hot water tank 12, The water having a temperature close to the high temperature water temperature can be floated to the upper part of the low temperature water tank 13. This is a situation that can be generated according to the operating conditions of the heat pump 20 or the cooling device 30. [

In this case, in order to keep the water in the hot water tank 12 at a high temperature and to keep the water in the low temperature water tank 13 at a low temperature, water having a low temperature in the hot water tank 12 is sent to the low temperature water tank 13, It is necessary to send water having a high temperature inside the water tank 13 into the high temperature water tank 12.

However, power must be used to cause water exchange between the high-temperature water tank 12 and the low-temperature water tank 13 in this way. However, in the present invention, the low temperature water in the high temperature water tank 12 is automatically sent to the low temperature water tank 13 while the high temperature water in the low temperature water tank 13 is sent to the high temperature water tank 12 automatically Respectively. This configuration is the heat exchange column 14 shown in Fig.

The heat exchange column 14 is in the form of a tube which connects the bottom of the hot water tank 12 and the top of the low temperature water tank 13 by utilizing the point that the hot water tank 12 is disposed on the upper side and the low temperature water tank 13 is disposed on the lower side . Therefore, when the lower part of the hot water tank 12 is connected to the upper part of the low temperature water tank 13, the hot water of the low temperature water tank 13 and the low temperature water of the hot water tank 12 may be exchanged.

In this case, in the present invention, the rising column 142 in which the water is raised and the falling column 141 in which the water is lowered are formed in different shapes so that the exchange can be performed as effectively as possible.

When the heat exchange column 14 is constructed to simply connect the lower portion of the hot water tank 12 and the upper portion of the low temperature water tank 13, the low temperature water below the hot water tank 12 is lowered, Can be prevented. In order to prevent such a case, the ascending column 142 is formed as shown in Fig. 3 so that the rise of the low temperature water is not obstructed. As shown in the enlarged view of FIG. 3, the upper end of the ascending column 142 is bent into the hot water tank 12 and is directed to the bottom of the hot water tank 12 in the process of being drawn. In this case, the low temperature water at the bottom of the hot water tank 12 can not be raised because the temperature is low and can not rise toward the end of the rising column 142. Instead, the high temperature water that has risen from the top of the low temperature water tank 13 And is sprayed toward the bottom of the high-temperature water tank 12. Therefore, in the ascending column 142, the falling of the low temperature water can be reliably prevented and the rise of the hot water can be assured.

On the other hand, in the descending column 141, the low temperature water placed on the bottom of the hot water tank 12 can be lowered toward the upper part of the low temperature water tank 13 without any appreciable interference. If the low temperature water temperature at the bottom of the high temperature water tank (12) is lower than the middle temperature water water temperature, the descending low temperature water can be smoothly lowered because it is heavier than the middle temperature water forming the external environment.

The elevated column 142 and the descending column 141 are separately constructed so that the low temperature water at the bottom of the high temperature water tank 12 is automatically injected into the low temperature water tank 13 and the high temperature water at the bottom of the low temperature water tank 13, The high temperature water is raised to the high temperature water tank 12 so that appropriate heat and material exchange occurs and the temperature of the high temperature water tank 12 and the low temperature water tank 13 can be maintained for a relatively long time during the operation of the cooling /

As described above, the triple chamber 10 is maintained in the inside of the thermostatic chamber 10 without any significant temperature change for a long time. Therefore, the cooling device 30 functions as a heat sink and a cool / The cooling device 30 and the heat pump 20, which function in a mutually opposite manner, are smoothly operated and the cooling device 30 and the heat pump 20 The operation of the triple chamber 10 can be kept constant so that the waste heat can be regenerated as efficiently as possible.

Hereinafter, the organic Rankine generator 60-60, which is a constitution that can be additionally provided for the detailed construction of the heat pump 20 and the cooling apparatus 30 and the waste heat more efficiently, 2, the solar heat collecting part 50 and the hot water tank 25, and the remaining detailed configuration for using the waste heat will be described.

The cooling device (30) and the heat pump (20) are all operated by refrigerant. 4, the heat pump 20 includes a first condenser 21, a first expansion valve 22, a first evaporator 23, and a first compressor 24, which are connected in order to circulate the refrigerant. And the cooling device 30 comprises a cycle in which the second condenser 31, the second expansion valves 32 and 321, the second evaporator 33 and the second compressor 34 are connected in order to circulate the refrigerant.

Here, the refrigerant of the first evaporator 23 is evaporated by the heat of the high temperature water supplied from the high temperature water tank 12, the high temperature water evaporated from the refrigerant of the first evaporator 23 is transferred to the low temperature water tank 13, 2 refrigerant in the evaporator 33 is evaporated into heat in the low temperature water tank 13 and the heat discharged from the second condenser 31 is transferred to the low temperature water in the low temperature water tank 13 and discharged from the second condenser 31 The low temperature water is transferred to the high temperature water tank 12.

7, the second evaporator 33 is preferably built in the low-temperature water tank 13 to evaporate the refrigerant of the second evaporator 33 by thermal energy in the low-temperature water tank 13, The condenser 21 is installed in a hot water tank provided for heating and hot water supply. The hot water tank 25 is provided separately from the heat pump 20 and functions to heat the internal water by thermal energy received from the condenser of the heat pump 20 to provide hot water or heating to the greenhouse complex.

Therefore, as shown in Fig. 7, the supply and demand of the hot water or the cold water is balanced. That is, the high-temperature water tank 12 is supplied with the low-temperature water heated by the second condenser 31 and balanced, and the low-temperature water tank 13 is supplied to the second condenser 31 The first evaporator 23 is supplied with the hot water that has been deprived of heat and is balanced.

However, since the amount of water required for the first evaporator 23 and the second condenser 31 may differ, in order to solve the unbalance in this case, the high-temperature water tank 12 is supplied with water A low temperature water tank (13) is installed in the low temperature water tank (13), and a low temperature water tank (13) valve is provided in the middle water tank (11).

Particularly, as shown in FIG. 7, the middle-temperature water introduced into the low-temperature water tank 13 through the low-temperature water tank 13 is first brought into contact with the second evaporator 33 built in the low-temperature water tank 13, The evaporation of the refrigerant flowing into the second evaporator 33 can be performed more smoothly than in an environment where only low temperature water is present.

In the present invention, as shown in FIG. 5, the solar heat collecting part 50 and the cooling tower 60-1 may be installed.

The solar heat collecting part 50 includes a solar heat collector 51 and a solar heating water tank 52 for storing hot water heated by the solar collector 51. In the daytime, The hot water in the solar heating water tank 52 may be transferred to the hot water tank 12 or may be transferred to the hot water tank 25 to be supplied as a heating or hot water source have.

Accordingly, by utilizing the natural energy of solar heat, the supply of heating and hot water in the cooling and heating system according to the present invention becomes more smooth and the hot water temperature of the hot water tank 12 can be maintained for a longer time.

As shown in FIG. 5, the cooling tower 60-1 serves to cool excess heat generated from the first condenser 21 during the summer season.

In this way, the cooling tower 60-1 can be operated to maintain the water temperature of the hot water and the low temperature water and to balance the water supply and demand in the summer during which the operation of the heat pump 20 is not required.

However, instead of balancing the supply and demand of high temperature water and low temperature water through the cooling tower 60-1 during the summer, a power generation unit 60-2 using an organic Rankine cycle is provided as shown in FIG. 6, -1) and energy can also be produced.

The power generation section 60-2 includes a power generation evaporator 61, a turbine 62 for driving the generator G, a power generation condenser 64, and a compression pump 65, The refrigerant discharged from the compressor 65 and the organic refrigerant delivered to the evaporator 61 for power generation is exchanged with the refrigerant discharged from the turbine 62. In this case, And the waste of heat is further minimized, so that thermal energy may be consumed in the production of electric power.

Here, like the cooling tower 60-1 described above, the power generation unit 60-2 operates to generate power with excess heat energy produced by the first condenser and supply power to the system according to the present invention.

The provision of the power generation unit 60-2 makes it possible to balance the supply and demand of heat and water between the hot water tank 12 and the low-temperature water tank 13 during the summer season, and at the same time, electric power is produced, minimizing waste of energy.

On the other hand, a greenhouse complex may contain a cooling facility (A-1). The third evaporator 332 is configured to cool the inside of the cooling facility A-1. The third evaporator 332 is installed in the cooling facility A-1 as shown in FIG. 7, while the refrigerant evaporated in the second evaporator 33 is supplied to the cooling facility A-1 ) The internal heat energy is absorbed by the refrigerant. Here, the refrigerant absorbed heat energy is discharged from the second evaporator 33, joined to the refrigerant pipe entering the second compressor 34, and then flows into the second compressor 34 together. 7 and 8, a third expansion valve 322 is installed in the refrigerant tube for supplying the refrigerant to the third evaporator 332. As shown in FIG.

Meanwhile, each of the one or more cooling / heating consumers A-2,3,4 constituting the greenhouse complex is provided with a cold magic air conditioner 401, and each cold / hot air conditioner 401 has an air conditioner / Each regeneration unit 72 is connected to the low temperature water tank 13 and the cooling water supply pipe 45 and is connected to the hot water tank 25 and the heating water supply pipe 47 to simultaneously supply low temperature water and heating water, Each of the heating / cooling controllers 72 is equipped with a valve that controls the mixing ratio of the low temperature water and the heating water so that the internal temperature of each of the cooling / heating consumers A-2,3,4 is adjusted by adjusting the mixing ratio .

The mixed water that has provided cooling or heating to the respective cooling or heating demand points A-2, 3 and 4 is discharged from each of the cold magic foam air conditioners 401, is collected by the four-way valve 74, A cooling water return pipe 73 which is transferred from the distribution valve 73 to the low temperature water tank 13 and which is transferred from the distribution valve 73 to the hot water tank 25, And returned.

The amount of the mixed water returned to the low temperature water tank 13 and the amount of the mixed water returned to the hot water tank 25 are respectively set to the low temperature water supplied from the low temperature water tank 13 to the heat consumers A- And a control unit (not shown) for returning the amount of heating water supplied from the hot water tank 25 to the heating demand sources A-2,3,4.

Therefore, although the water recovered by the low-temperature water tank 13 or the hot water tank 25 is mixed water whose temperature has changed, only the amount corresponding to the supplied amount is recovered so that the width of the temperature change inside the low-temperature water tank 13 or the hot water tank 25 is minimized .

At the same time, the users of heating and cooling units constituting the greenhouse complex can receive appropriate heating and cooling according to the situation at different temperatures, and the user can control the temperature as much as possible.
