Hereinafter, the air-conditioning and hot water supply apparatus using the heat pump of the present invention will be described in detail with reference to the accompanying drawings.

As shown in the figure, in the existing large building, the cooling device 10 and the heating device 20 are installed as separate systems, respectively, and the heat pump 30 connected to the cooling device 10 and the heating device 20. ) Is provided but the cooling load of the cooling device 10 or the cooling load of the first condenser 12 can be reduced by applying cooling air to the first evaporator 14 or the first condenser 12 of the cooling device 10. By applying warmth to the hot water supply and heating tank 24 of the heating device 20, the heating load of the heating device 20 may be reduced or the operating time of the heater 22 may be reduced.

The air conditioning apparatus 10 includes a first compressor 11, a first condenser 12, a first expansion valve 13, and a first booster so that the refrigerant is compressed, cooled, and becomes a liquid and vaporized. Erection 14 is composed of one cycle, and a separate cooling tower 15 for cooling and condensing the refrigerant of the first condenser 12 is provided, but the cooling tower 15 in the first condenser 12 Cooling line (15a) is provided to be circulated up to the first and the cooling line (15a) is provided with a first circulation pump 16 for controlling while circulating the cooling fluid on the cooling line (15a).

The heating device 20 is provided with a boiler 23 having a burner or a heater 22 in the heat exchanger 21 and connected to the heat exchanger 21 through a heating line 24a to heat exchanger 23. It consists of a hot water supply and a heating tank 24 for storing the warmed hot water from, the hot water supply and heating tank 24 is connected to the heating or hot water supply line (24b) up to the room (40) requiring heating or hot water supply And a water supply line 24c connected to the water supply from the water supply source. The heating line 24a includes a third circulation pump for continuously circulating the fluid (water) in the hot water supply and heating tank 24 back to the hot water supply and heating tank 24 through the heat exchanger 21 ( 25) is provided.

The heat pump 30 has a second compressor 31, a second condenser 32, a second expansion valve 33 and a second evaporator so that the refrigerant is compressed and cooled to become a liquid and vaporized. 34 constitutes another cycle.

The first evaporator 14 of the cooling device 10 is provided with a cooling line 14a circulated back to the first evaporator 14 through the room 40 to be cooled by the first evaporator 14. However, the cooling fluid flows from the middle of the cooling line 14a passing through the room 40 to the first evaporator 14 of the cooling device 10 through the second evaporator 34 of the heat pump 30. The first connection line 34a is connected to be circulated. The cooling line 14a is provided with a second circulation pump 17 for controlling the flow of the cooling fluid while circulating the cooling fluid in the cooling line 14a.

Between the second condenser 32 of the heat pump 30 and the hot water supply and heating tank 24 of the heating device 20, the fluid of the hot water supply and heating tank 24 is heated and heated through the second condenser 32. The second connection line 32a is connected to the tank 24, and the second condenser 32 is sucked into the second connection line 32a by sucking the fluid (water) in the hot water supply and heating tank 24. A fourth circulation pump 35 is provided to control the flow of the fluid while supplying the water to the hot water supply and heating tank 24 again.

It will be described in detail the operation of the heating and heating and hot water supply apparatus using the heat pump of the embodiment configured as described above.

When the air conditioner 10 is operated during a hot summer season, as the first compressor 11 is driven, the refrigerant is supplied from the first compressor 11 to the first condenser 12 to the first expansion valve 13 to the first compressor. A cycle circulated through the evaporator 14 → the first compressor 11 is achieved.

Since the refrigerant circulated in the cycle as described above is compressed by the first compressor 11 and is compressed to high temperature and high pressure, and then is supplied to the first condenser 12, the refrigerant in the first condenser 12 emits heat. Simultaneously, when the first circulation pump 16 on the cooling line 15a is operated while the cooling tower 15 is operated, the cooling fluid in the cooling line 15a is continuously moved along the cooling line 15a. At this time, the cooling fluid in the cooling line 15a is cooled by the cooling tower 15, and then the process of returning back to the cooling tower 15 through the first condenser 12 of the cooling device 10 is continuously performed. Therefore, since the refrigerant of the first condenser 12 absorbs heat, the refrigerant is cooled and condensed.

As described above, the refrigerant cooled and condensed in the first condenser 12 becomes low pressure in the first expansion valve 13 and vaporizes in the first evaporator 14 to absorb external heat. At this time, since the second circulation pump 17 on the cooling line 14a is driven, the cooling fluid is moved along the cooling line 14a and the first connection line 34a. Thus, the cooling fluid is the cooling device 10. After cooling in the first evaporator 14 of the cooling is moved to the room 40 to be cooled along the cooling line (14a) to perform the cooling. The cooling fluid warmed while performing the cooling is returned to the first evaporator 14 of the cooling device 10 through the second evaporator 34 of the heat pump 30 installed on the first connection line 34a. Will continue to cycle.

The low pressure refrigerant vaporized in the first evaporator 14 of the cooling device 10 and deprived of heat from the cooling fluid of the cooling line 14a is sucked and compressed by the first compressor 11 to become a high temperature and high pressure. The compressed refrigerant is continuously circulated from the first condenser 12 to the first expansion valve 13 to the first evaporator 14 as described above.

The heating device 20 may be operated so that a shower, a bath, or the like may be performed in the summer when the air conditioner 10 is operated. When the heating device 20 is operated, power is applied to the heater 22 and the fluid (cold water) in the heat exchanger 21 is heated to obtain hot water at a predetermined temperature. The hot water thus obtained is removed from the heating line 24a. The three circulation pumps 25 are operated to be supplied to the hot water supply and heating tank 24 to be temporarily stored and to connect the hot water of the hot water supply and heating tank 24 to a room requiring heating or hot water supply. It supplies to (24b).

As described above, the cooling device 10 and the heating device 20 may be operated separately, and at the same time, the heat pump 30 may be operated. When the heat pump 30 is operated together with the cooling and heating devices 10 and 20, the coolant is driven as the heat pump 30 is also driven by the second compressor 31 as in the case where the cooling device 10 is operated. The second compressor (31) → the second condenser (32) → the second expansion valve (33) → the second evaporator (34) → the second compressor (31) is circulated through the cycle.

Since the refrigerant circulated in the cycle as described above is compressed by the second compressor 31 and is compressed to high temperature and high pressure, and then supplied to the second condenser 32, the second condenser 32 condenses by dissipating heat of the refrigerant. The refrigerant condensed in the second condenser 32 becomes low pressure in the second expansion valve 33 and then vaporizes in the second evaporator 34 to absorb external heat, and then, by the second compressor 31. Repeat the process of suction compression to high temperature and high pressure.

Heat dissipated from the second condenser 32 of the heat pump 30 is sucked into the hot water in the hot water supply and heating tank 24 by the fourth circulation pump 35 of the second connection line (32a) to the second condenser The hot water circulated further by supplying the hot water supply and the heating tank 24 through the 32 is further heated. Therefore, warmer hot water can be obtained, thereby reducing the load of the heating device 20 or reducing the running time of the heater 22 of the heating device 20. In summer, when a large amount of hot water is not required, the heater 22 of the heating device 20 may not be operated at all.

At the same time, the second evaporator 34 of the heat pump 22 must absorb the heat of vaporization necessary for vaporization of the refrigerant, so that the second circulation pump 17 on the cooling line 14a is driven to form one circulation circuit. The heat is taken from the cooling fluid circulated along the 14a and the first connection line 34a to cool.

Therefore, the second evaporator 34 of the heat pump 30 adds cool air to the cooling fluid circulated along the cooling line 14a and the first connection line 34a of the cooling device 10, thereby cooling By reducing the load on the device 14a, overload can be prevented in advance.

And in the spring or autumn with less cooling load in the cooling and heating and hot water supply apparatus using the heat pump of the present invention, only the heat pump 30 can be operated without operating the cooling apparatus 10.

In this case, cooling can be performed by activating the second circulation pump 17 installed in the cooling line 14a of the cooling device 10 to circulate the cooling fluid of the cooling line 14a and the first connection line 34a. And the second condenser 32 of the heat pump 30 by operating only the fourth circulation pump 35 installed in the second connection line 32a of the heat pump 30 without operating the heating device 20. Since the cold water in the hot water supply and heating tank 24 is heated, hot water can be obtained. Therefore, the hot water can be obtained while performing cooling by operating only the heat pump 30.

Figure 2 is a view showing another embodiment of the heating and heating and hot water supply apparatus using a heat pump according to the present invention. Here, the cooling line 14a of the air conditioner 10 is circulated to the first evaporator 14 of the air conditioner 10 via the room 40 to perform cooling in the first evaporator 14. The first connection line 34a of the cooling device 10 is circulated through the first condenser 12 of the cooling device 10, the cooling tower 15, and the second evaporator 34 of the heat pump 30. Except that connected to the cooling line (15a) is the same as the configuration of one embodiment of the present invention.

According to the configuration of another embodiment as described above, the cooling device operates the cooling device 10 and the cooling device without receiving cooling air from the second evaporator 34 of the heat pump 30 even when the heat pump 30 is operated. Only by the first evaporator 14 of (10), except that the first connection line (34a) is connected to the cooling line (15a) of the cooling device 10, the cooling fluid therein is a heat pump (30) When is operated, the first circulation pump 16 on the cooling line 15a is circulated along the cooling line 14a and the first connection line 34a forming one circulation circuit.

As such, the second evaporator 34 of the heat pump 30 must absorb the heat of vaporization necessary for the vaporization of the refrigerant during the circulation of the cooling fluid, thereby taking heat away from the cooling fluid on the first connection line 34a and cooling it. The cooled cooling fluid is reliably cooled again in the cooling tower 15, and then heat is removed from the first condenser 12 of the cooling device 10 to condense the first condenser 12 of the cooling device 10 more reliably. .

Therefore, the second evaporator 34 of the heat pump 30 cools the cooling fluid cooled by the cooling tower 15 of the cooling line 15a of the cooling device 10 again more reliably, thereby cooling the cooling device 10. It is possible to reduce the load on the thereby it is possible to prevent the overload of the cooling device 10 in advance.

Figure 3 is a view showing another embodiment of the heating and cooling and hot water supply apparatus using a heat pump according to the present invention. Here, the first connection line 34a is simultaneously connected to the cooling line 14a and the cooling line 15a of the cooling device 10, and the cooling line 14a or the cooling line 15a of the cooling device 10 is connected. In the second evaporator 34 of the heat pump 30, the valves 36a and 36b are provided to control the flow to selectively circulate the cooling and cooling fluids in one cycle.

Operation of the configuration of another embodiment as described above is the same as the cooling line (14a) and the cooling line (15a) is connected to the first connection line (34a), its specific operation is omitted. As described above, the cooling line 14a or the cooling line 15a of the cooling device 10 is connected to the first connection line 34a to be circulated through the second evaporator 34 of the heat pump 30. Therefore, it is possible to add cooling air to the cooling fluid circulated along the cooling line 14a of the cooling device 10 or to efficiently cool the cooling fluid circulated along the cooling line 15a of the cooling device 10. Therefore, the cooling line 14a or the cooling line 15a of the cooling device 10 can be freely selected and operated regardless of whether the heat pump 30 is operated.

Figure 4 is a view showing another embodiment of the heating and cooling and hot water supply apparatus using a heat pump according to the present invention. Here, the first connection line 34a is simultaneously connected to the cooling line 14a and the cooling line 15a of the air conditioner 10 as shown in FIG. 3, and is further branched from the first connection line 34a to form a large building. A waste heat recovery line 42a for returning the waste water treatment plant 42 by circulating back is added, and the waste heat recovery line 42a has a valve 37 for controlling the flow of cooling fluid to the waste heat recovery line 42a. And a fifth circulation pump 38 is provided.

Since the cooling line 10 and the cooling line 15a are the same as those connected to the first connection line 34a among the operations of the configuration of another embodiment as described above, the detailed operation thereof will be omitted and the heat pump ( Only the case in which the first connection line 34a of 30) is connected to the waste heat recovery line 42a will be described. In this case, when the air conditioner is not needed in the season when the air conditioner 10 is not used, that is, when the air conditioner is not operated, the waste heat recovery line (a) is closed while the valves 36a and 36b on the cooling line 14a and the cooling line 15a are locked. The heat pump 30 is operated while opening the valve 37 on 42a) and operating the fifth circulation pump 38.

As described above, since the heat pump 30 is compressed by the second compressor 31 and compressed at a high temperature and high pressure, the heat pump 30 is supplied to the second condenser 32. Thus, the second condenser 32 dissipates and condenses heat of the refrigerant. The refrigerant condensed in the second condenser 32 becomes low pressure in the second expansion valve 33 and then vaporizes in the second evaporator 34 to absorb external heat, and then the second compressor 31. The process of suction compression by the high temperature and high pressure is repeated.

Heat dissipated from the second condenser 32 of the heat pump 30 is sucked into the hot water in the hot water supply and heating tank 24 by the fourth circulation pump 35 of the second connection line (32a) to the second condenser The hot water circulated by heating the hot water circulated again by supplying it to the hot water supply and heating tank 24 through 32.

In addition, since the second evaporator 34 of the heat pump 30 must absorb the vaporization heat necessary for vaporization of the refrigerant, the fifth circulation pump 38 on the waste heat recovery line 42a is driven to form one circulation circuit. Heat is removed from the cooling fluid circulated along the line 42a and the first connection line 34a, and the cooling fluid in the waste heat recovery line 42a passes through a wastewater treatment plant such as a large building, and has waste water. To take advantage of it.

Therefore, hot water can be obtained through the second condenser 32 of the heat pump 30 without operating the heating device 20, and the hot water obtained through the second condenser 32 of the heat pump 30 is heated and heated. Supply to the tank 24 can be utilized for hot water supply and heating can reduce the operating time of the heating device or reduce the load.

The present invention can be usefully used for the water heater device as well as the heating device of the water heat exchange system installed separately from the cooling device and the heating device of a large building.
