The high-temperature heat pump 110 is a cooling / heating device that transfers a low-temperature heat source to a high temperature or transmits a high-temperature heat source to a low temperature by using heat of a refrigerant or condensation heat. ) And the inner space 220 in order to smoothly and continuously supply the heating medium (C) or the heating medium (H).

The high-temperature heat pump 110 having such a configuration can be operated as a whole, or can be operated by controlling the number of one or two or three.

The heat source of the cooling medium (C) or the heating medium (H) according to the present invention may be air, well water, solar heat, geothermal heat, or the like.

The flow path P includes a first flow path P1, a second flow path P2, a third flow path P3, and a fourth flow path P4.

The first flow path P1 is located on the upper side with respect to the cold and hot medium storage tank 140 and includes a high temperature heat pump 110, a thermal medium switching valve 130, 140 and the greenhouse 200 so as to be used as a flow path for supplying the cooling medium C or the heating medium H.

The second flow path P2 is located on the lower side with respect to the cold and hot medium storage tank 140 and includes a high temperature heat pump 110, a thermal medium switching valve 130, a cold and hot medium storage tank 140, And is connected to the greenhouse 200 and used as a channel for supplying or supplying the cooling medium C or the heating medium H,

The third flow path P3 is located forward or left on the basis of the cold and hot medium storage tank 140 and connects the first flow path P1 and the second flow path P2 to the coolant medium C, Is used as a flow path for supplying the medium (H) or as a flow path for returning the medium (H).

The fourth flow path P4 is located behind or on the right side of the coolant storage tank 140 and connects the first flow path P1 and the second flow path P2 to the coolant medium C, Is used as a flow path for supplying the medium (H) or as a flow path for returning the medium (H).

The temperature of the cooling medium C or the heating medium H supplied or returned to one side of the first flow path P1, the second flow path P2 or the third flow path P3 and the fourth flow path P4 A temperature sensor S for sensing the temperature of the substrate W is formed.

The convection circulation pump 120 serves to return the cooling medium C or the heating medium H returned to the cooling and heating medium storage tank 140 to the high temperature heat pump .

That is, the convection circulation pump 120 sends the cooling medium C or the heating medium H, which is returned to the cooling and heating medium storage tank 140, to the high-temperature heat pump 110 through the flow path P Thereby performing heat exchange.

The thermal medium switching valve 130 is a three way valve that is provided through the flow path P to switch the flow of the cooling medium C or the heating medium H, And a rear heating medium switching valve 132. The front heating medium switching valve 131 and the rear heating medium switching valve 132 are connected to each other.

The front heating medium switching valve 131 is composed of a first front valve 131a and a second front valve 131b, a third front valve 131c and a fourth front valve 131d, The valve 132 includes a first rear valve 132a and a second rear valve 132b and a third rear valve 132c and a fourth rear valve 132d and a fifth rear valve 132e.

The three-way valve is partially opened or closed by the signal of the temperature sensor S to switch the heating medium switching valve 131 and the rear heating medium switching valve 132 to the cooling medium C ) Or the flow path of the heating medium (H).

The cooling / heating medium storage tank 140 is capable of reducing the capacity of a heat source device (cooling / heating system) by averaging the peak load in cooling and heating, and stores the cooling medium C or the heating medium H therein It is a role to play.

In this case, the stratification phenomenon occurs in the cold and hot medium storage tank 140 due to the density difference due to the water temperature change according to the depth, that is, the surface layer having a high temperature and the low water temperature layer are formed. A plurality of diffusers 141 are preferably formed on the inner side and the lower side to prevent a stratification phenomenon in which a thermocline is formed which changes abruptly.

The circulation pump 150 circulates the cooling medium C or the heating medium H supplied through the cooling and heating medium storage tank 140 and the heating medium switching valve 130 to the greenhouse 200, And an inner circulation pump 152 for sending the circulation pump 151 to the inner space 220.

The greenhouse 200 may be divided into an edge space 210 and an inner space 220 and a thermal insulation space may be formed between the edge space 210 and the inner space 220.

Accordingly, heat transfer between the edge space 210 and the inner space 220 can be blocked to maximize the energy efficiency of the inner space 220.

First of all, the heating of the greenhouse 200 will be described in more detail in a greenhouse cooling / heating method sharing the heat pump of such a configuration.

In step (a), the heating medium H having a high temperature of 65 ° C or more is supplied to the edge space 210 and the inner space 220 of the greenhouse 200 through the cooling / heating system 100 including the heat pump 110 Respectively. (S10)

That is, the hot medium H generated at a high temperature, for example, at a temperature of 65 ° C by the high temperature heat pump 110 is supplied to the cold and hot medium storage tank 140 through the first flow path P1.

The heating medium H supplied to the inside of the cooling and heating medium storage tank 140 through the first flow path P1 is uniformly diffused into the cooling and heating storage tank 140 through the diffuser 141 do.

The heating medium H introduced into the cooling and heating medium storage tank 140 is discharged to the outside through the first flow path P1 and the first rear valve 132a and the second rear valve 132b and the third rear valve 132c, To the edge circulation pump 151 and the inner circulation pump 152 to be separated and supplied to the edge space 210 and the inner space 220 of the greenhouse 200 at a high temperature of, for example, 65 ° C or more.

That is, the heating medium H supplied to the edge space 210 of the greenhouse 200 can be supplied by the high-temperature heat pump 110, unlike the conventional heating temperature of 45 ° C. to 50 ° C. It is preferable to supply at a high temperature of 65 占 폚 or higher, which is the highest temperature.

Accordingly, since the heat of the heat medium H supplied to the inner space 220 is prevented from being released to the outside or lost, the heat loss can be minimized even in the cold winter so that the total energy cost can be reduced Can be remarkably reduced.

In the step (b), the temperature of the heating medium H, which is recovered after the heating of the greenhouse 200, is sensed and the heated medium H, which is recovered on the basis of the temperature at which the temperature of the heating medium H can be heated, 200, or is returned to the cold / hot medium storage tank 140. (S20)

That is, the temperature of the heating medium H after the heating of the greenhouse 200 is lower than the temperature sensed by the temperature sensor S formed on one side of the second flow path P2 during the process of being returned through the second flow path P2 The third rear valve 132c and the fifth rear valve 132e close the fourth flow path P4 that flows to the edge circulation pump 151 and the inner circulation pump 152 And the second flow path P2 that flows to the cold storage heat storage tank 140 partially opens so that a part of the heating medium H flows into the inner space 220 of the greenhouse 200 And a part thereof is returned to the cold / hot storage tank 140.

When the temperature of the heating medium H is lower than 50 ° C and lower than 55 ° C, the inside of the greenhouse 200 is partially heated.

Accordingly, a part of the high-temperature heat pump 110 is operated to heat the cold / hot-medium storage tank 140, the first flow path P1, the first rear valve 132a, the second rear valve 132b, The heating medium H having a temperature higher than 65 ° C is supplied to the edge space 210 of the greenhouse 200 through the edge circulation pump 151.

When the temperature sensed by the temperature sensor S is equal to or higher than 55 ° C, the temperature of the heating medium H, which is returned through the second flow path P2, is lower than the second rear valve 132b and the third rear valve 132c And the fifth rear valve 132e are opened so that the heating medium H flowing to the edge circulation pump 151 and the inner circulation pump 152 flows into the edge space 210 and the inner space 220 .

The present invention having such a configuration resets the size of the cooling and heating medium storage tank 140 by re-supplying the heating medium H, which is returned by the rear valve 131 and the temperature sensor S, (Capacity) can be reduced, which can significantly reduce facility investment costs.

In step (b), the temperature of the heating medium H to be returned to the greenhouse 200 after the heating of the greenhouse 200 is sensed. When the temperature of the heating medium H is unheatable, the cooling and heating medium storage tank 140 is completely returned.

That is, when the temperature sensed by the temperature sensor S is lower than or equal to 50 ° C, the heating medium H, which is returned through the second flow path P2, passes through the fourth rear valve 132d and the fifth rear valve 132e The first circulation pump P1 and the first circulation pump P1 are closed by the circulation pump 151 and the inner circulation pump 152 so that the heating medium H is returned to the cold storage medium storage tank 140.

At the same time, the hot medium H having a temperature higher than 65 ° C discharged from the cold / hot medium storage tank 140 and the first flow path P1 flows through the first rear valve 132a and the second rear valve 132b, And is supplied to the edge space 210 of the greenhouse 200 through the circulation pump 151.

Next, a method of cooling the greenhouse 200 during the step (a) using the heating / cooling system 100 including the heater pump according to the present invention will be described in more detail as follows.

In step (a), the cooling medium C at 7 ° C is divided into the edge space 210 and the inner space 220 of the greenhouse 200 through the cooling / heating system 100 including the heat pump 110 Supply. (S10)

That is, the coolant medium C generated at a low temperature, for example, 7 캜, by the high-temperature heat pump 110 is cooled through the first flow path P1, the third flow path P3, , And is supplied to the thermal medium storage tank (140).

At this time, the cool medium (C) supplied into the cold / hot medium storage tank 140 is uniformly diffused into the cool / hot storage tank 140 through the diffuser 141.

The cooling medium H flowing into the cooling and heating medium storage tank 140 flows through the second flow path P2 and the fifth rear valve 132e and the second rear valve 132b and the third rear valve 132c, And is supplied to the edge circulation pump 151 and the inner circulation pump 152 through the circulation pipe 151 and the inner space 220 and the edge space 210 and the inner space 220 of the greenhouse 200 at a low temperature,

That is, the cooling medium C supplied to the edge space 210 of the greenhouse 200 is supplied at a low temperature of 7 ° C, unlike the conventional cooling temperature of 15 ° C to 17 ° C.

Accordingly, since the cold air of the coolant medium (C) supplied to the inner space (220) is prevented from being released to the outside or lost, it is possible to minimize the heat loss even in the hot summer. Can be remarkably reduced.

In step (b), the temperature of the cooling medium (C) to be returned after cooling of the greenhouse (200) is sensed and the cooling medium (C), which is recovered on the basis of the temperature at which the temperature of the cooling medium Or is returned to the hot and / or hot medium storage tank 140. (S20)

That is, after the cooling of the greenhouse 200, the cooling medium C is circulated through the second flow path P2 and the first flow path P1, S is higher than 12 ° C and lower than 17 ° C, a part of the flow rate is returned to the cold / hot storage tank 140 through the first flow path P1, and the remaining part of the flow rate is supplied to the inner circulation pump 152 To the inner space (220) of the greenhouse (200).

When the temperature of the cooling medium C to be returned is higher than 12 ° C and less than 17 ° C, the inside of the greenhouse 200 is judged to be partially in need of cooling.

Accordingly, a part of the high-temperature heat pump 110 is operated to discharge the cold and hot medium storage tank 140, the first flow path P1, the third flow path P3 and the fourth flow path P4, The cooling medium C of 7 ° C is supplied to the edge space 210 of the greenhouse 200 through the rear valve 132e, the second rear valve 132b and the edge circulation pump 151.

When the temperature detected by the temperature sensor S is equal to or lower than 12 캜, the cooling medium C, which is returned through the second flow path P 2 and the first flow path P 1, A part of the second rear valve 132b and the third rear valve 132c are opened to allow the coolant medium C to flow through the edge space 210 and the inner space through the edge circulation pump 151 and the inner circulation pump 152, To be supplied to the inner space 220 again.

The present invention having such a configuration resumes the size of the cooling and heating medium storage tank 140 by re-supplying the cooling medium C, which is returned by the rear valve 131 and the temperature sensor S, (Capacity) can be reduced, which can significantly reduce facility investment costs.
