A constant oil compressor 121 is installed between the constant speed compressor 120 and the inverter compressor 120 'to allow the constant speed compressor 120 and the inverter compressor 120' to communicate with each other. Therefore, when oil supply shortage occurs in one of the compressors, the compressor 120 is replenished from the other compressor to prevent burnout of the compressors 120 and 120 'due to the insufficient flow rate.

As the compressors 120 and 120 ', a low noise and excellent scroll compressor is used. In particular, the inverter compressor 120' is an inverter scroll compressor whose rotation speed is adjusted according to the load capacity. Therefore, when a small number of indoor units 200 are used and the load capacity is small, the inverter compressor 120 'is operated first, and when the load capacity is gradually increased, the inverter compressor 120' can not afford only the constant speed compressor ( 120 is activated.

At the outlet side of the constant speed compressor 120 and the inverter compressor 120 ', the compressor discharge temperature sensors 120b and 120'b and the oil separator 122 for measuring the refrigerant temperature discharged from the compressors 120 and 120' are respectively provided. . The oil separator 122 filters the oil mixed in the refrigerant discharged from the compressors 120 and 120 'to be recovered to the compressors 120 and 120'.

The oil in the refrigerant is separated into the oil separator 122. Is separated and sent back to the compressor (120,120 ').

In addition, a non-return valve 122 ′ is further provided at an outlet side of the oil separator 122 to prevent a reverse flow of the refrigerant. That is, when only one of the constant speed compressor 120 or the inverter compressor 120 'is operated, the compressed refrigerant is not flowed back into the compressor 120/120' that is stopped.

The oil separator 122 is configured to communicate with the four-way valve 124 by the pipe. The four-way valve 124 is arranged to change the flow direction of the refrigerant according to the cooling and heating operation, each port is an outlet (or oil separator) of the compressor (120, 120 '), the inlet (or the compressor 120, 120') Accumulator), outdoor heat exchanger 180 and the indoor unit 200 is connected.

Therefore, the refrigerant discharged from the constant speed compressor 120 and the inverter compressor 120 'is collected in one place and then flows into the four-way valve 124.

Meanwhile, the four-way valve has a hot gas pipe 125 that allows a part of the refrigerant flowing into the four-way valve 124 from the oil separator 122 to be directly introduced into the accumulator 132 which will be described below. 124 is installed across.

Therefore, the refrigerant passing through the outdoor supercooler 130 is a temperature desired by the user. That is, as the amount of refrigerant flowing back through the back transfer pipe 130 ′ increases, the temperature of the refrigerant passing through the outdoor supercooler 130 will be lowered.

When a part of the refrigerant discharged from the outdoor supercooler 130 is introduced into the reverse conveying pipe 130 'by the above configuration, the low temperature gas refrigerant is expanded while passing through the subcooling expansion valve 130'a. The low temperature gas refrigerant flows back through the outer tube (not shown) of the outdoor supercooler 130 to further cool the liquid refrigerant flowing through the inner tube (not shown) through heat exchange.

Since the measured pressure measured at is less than a target high pressure sufficient for heating, the bypass pipe 140 bypasses the refrigerant compressed by the compressor 120 to the lower portion of the outdoor heat exchanger 180.

In this case, the predetermined target high pressure may be selectively changed according to the load of the indoor unit 200, the hot water supply device 500, and the water heating and heating device 600.

One side of the first circulation tube 712 is provided with an overheat prevention tube (720). The overheat prevention tube 720 is configured so that the first circulation tube 712 and the third circulation tube 716 communicate with each other, and an overheat cutoff valve 722 is provided at one side of the overheat prevention tube 720.

The superheat cutoff valve 722 selectively opens the superheat cutoff tube 720 to branch a portion of the refrigerant flowing through the first circulation pipe 712 into the third circulation pipe 716, thereby preheating the refrigerant. Blocking, thereby preventing overheating of the refrigerant.

One side of the first circulation pipe 712 is provided with an oil circulation pipe 730. The oil conduit 730 is provided with an on-off valve 732 to allow the refrigerant flow selectively.

That is, a heating expansion valve 740 is provided below the oil pipe 730, and the heating expansion valve 740 expands the refrigerant when the refrigerant heating means 750 to be described below is used as an evaporator.

Therefore, when the refrigerant flows through the first circulation pipe 712 while the on / off valve 732 shields the oil pipe 730, the refrigerant can be expanded through the heating expansion valve 740.

A refrigerant heating means 750 is provided at the center of the refrigerant heating device 700. The refrigerant heating means 750 is a plate heat exchanger is applied as a configuration for heat exchange between the refrigerant circulating through the refrigerant circulation pipe 710 and water.

That is, a heating water channel 752 through which water flows is coupled to the right side of the refrigerant heating means 750, and the heated water channel 752 circulates the heated water through the water heating means 760. The refrigerant passing through the inside of the refrigerant heating unit 750 and water flow in a state separated from each other to heat the refrigerant by heat exchange.

To this end, a water heating means 760 is provided on the right side of the heating expansion valve 740. The water heating means 760 includes a water heating unit 762 through which the heating water passage 752 passes through, and a heating source 764 for providing heat to the water heating unit 762.

The heating source 764 may be variously modified and implemented within a range capable of heating the water heater, and for example, gas, oil, heat, solar heat, and the like may be applied.

In addition, a water pump 770 is provided at one side of the heating channel 764 to force the water in the heating channel 752 to circulate, and both ends of the heating channel 752 are heated in the tank 780. ) Is configured to communicate with the inside.

The water of the predetermined level is stored in the heating tank 780, the water in the heating tank 780 is circulated along the heating water path (752).

Therefore, the water heated by the water heating means 760 while moving along the heating water passage 752 is stored in the heating tank 780.

On the other hand, between the hot water supply device 500 and the refrigerant heating device 700 is provided with a hot water forcing device 800, which is a main component of the present invention.

The hot water forcing device 800 is configured to allow the user to use hot water quickly.

That is, the hot water supply device 500 may provide hot water to the user by using the heat provided from the water heat exchanger 400, but the hot water supply device 500 in the embodiment of the present invention is hot water forcing means 800 The user may be provided with heat from the hot water.

Hereinafter, the configuration of the hot water forcing device 800 will be described in detail with reference to FIGS. 4 and 5.

As shown in these figures, the hot water forcing device 800 is a hot water supply water pipe 820 to circulate water between the hot water supply device 500 and the refrigerant heating device 700, and the water inside the hot water supply water pipe 820. Hot water pump 840 forcing the flow, the water flow sensor for detecting the flow of water in the hot water supply pipe 820 (reference numeral 860 in Figure 1), and the water temperature inside the hot water supply pipe 820 It is configured to include a hot water temperature sensor 880 to measure.

The hot water supply pipe 820 is configured to communicate with the hot water supply pipe 580 so that the water heated in the refrigerant heating device 700 may provide heat to the hot water supply device 500.

That is, the water inside the hot water supply water pipe 820 is forced to flow by the hot water pump 840, and is heated in the water heating means 760, and the heated water is inside the hot water tank 510. After passing through the hot water supply pipe 580 is heated through the water stored in the hot water tank (510).

Then, the water discharged through the hot water supply pipe 580 is introduced into the refrigerant heater 700 again through the water supply water pipe 820 and heated.

One side of the hot water supply pipe 820 is provided with a hot water temperature sensor 880 for measuring the temperature of the water flowing inside. The hot water temperature sensor 880 measures the temperature of the water flowing into the water heating means 760 and the temperature of the water passing through the water heating means 760 to determine whether the water is being heated by the water heating means 760. , How much heat is heated, etc.

Accordingly, the hot water temperature sensor 880 measures the temperature of the water heated through the cold water temperature sensor TH8 and the coolant heater 700, which measures the temperature of the water flowing into the coolant heater 700. It is configured to include a hot water temperature sensor (TH9).

The cold water temperature sensor TH8 and the hot water temperature sensor TH9 allow the amount of heat provided by the water heating means 760 to the hot water supply water pipe 820 according to the detected water temperature.

That is, when the temperature of the water heated by the water heating means 760 is low, even if it moves along the hot water supply pipe 820, the amount of heat to heat the water stored in the hot water tank 510 is insufficient, so Cooling, this temperature is compared to the measured water temperature measured by the cold water temperature sensor (TH8) and hot water temperature sensor (TH9) by allowing the water heating means 760 to heat up to a higher temperature It may be possible to use hot water quickly.

On the other hand, the hot water forcing device 800 may be selectively used. That is, the hot water forcing device 800 may be used when the user wants to use hot water quickly, but when using only heating without using hot water The hot water forcing device 800 need not be used.

In this case, the hot water supply pump 840 is stopped, and the hot water supply pipe 820 is further provided with a hot water exclusive valve 890. The hot water exclusive valve 890 is configured to heat the water in the hot water tank 510 using the refrigerant heater 700, and to enable hot water to be used as the heated water. When the heat pump refrigerant cycle is used, The hot water supply valve 890 is shielded.

In more detail, the hot water supply valve 890 includes an inlet cutoff valve 892 for selectively blocking the flow of water introduced into the hot water supply device 500, and the water inside the hot water supply device 500 to the outside. It is configured to include an outlet shut-off valve (894) to block the outflow, the inlet shut-off valve 892 and the outlet cut-off valve 894 is to shield or open the hot water supply pipe 820 at the same time.

Hereinafter, the operation of the heat pump interlocking hot water circulation system configured as described above will be described through the flow of refrigerant and water.

First, the fixing of air, floor heating, and hot water using the refrigerant heating device 700 and the outdoor unit 100 in the extreme cold will be described with reference to FIG. 6.

At this time, the bypass guide valve 144 and the outdoor expansion valve 102, the overheat cut off valve 722, the hot water valve 582 and the heating valve 632 is in an open state, the overheat cutoff valve 722 The on / off valve 732 and the hot water supply valve 890 are shielded.

The hot water pump 840 maintains a stopped state.

Looking at the refrigerant flow in the outdoor unit 100, the refrigerant discharged from the compressor (120, 120 ') is passed through the oil separator 122 and flows into the distributor 300 through the high-pressure engine (214).

In the distributor 300, each main valve 330 is turned off, and each auxiliary valve 332 is turned on and opened. Therefore, the refrigerant introduced into the distributor 300 through the high pressure engine 214 flows into the indoor engine 212 ′ through the branch pipe 340.

The refrigerant introduced into the indoor engine 212 ′ through the branch pipe 340 is supplied to the indoor unit 200 and condensed through heat exchange with indoor air while passing through the indoor heat exchanger 202.

That is, in the case of heating, the indoor heat exchanger 202 acts as a condenser to warm the internal air by heat generation. Since the expansion valves 204 are all open, the refrigerant changed into a liquid phase while passing through the indoor heat exchanger 202 flows into the distributor 300 through the indoor liquid pipe 210 '.

The liquid refrigerant in the distributor 300 is introduced into the outdoor unit 100 through the liquid pipe 210. The refrigerant introduced into the outdoor unit 100 passes through the outdoor LEV 102 and is supplied to the outdoor heat exchanger 180 to generate heat exchange. At this time, since the outdoor heat exchanger 180 acts as an evaporator, the liquid refrigerant is changed to the gas phase by heat exchange with external air.

The low-pressure refrigerant in the gas phase discharged from the outdoor heat exchanger 180 passes through the four-way valve 124 and is supplied to the compressors 120 and 120 ′ via the accumulator 132. Through this process, one heating cycle is formed.

Meanwhile, some of the refrigerant passing through the outdoor supercooler 130 is introduced into the refrigerant heating device through the first refrigerant pipe 162 and the first circulation pipe to circulate.

In this case, the heating source 764 provides heat to the water heater 762, and the heat heats the water circulating through the heating tank 780 and the water heater 762.

The heated water exchanges heat with the refrigerant via the refrigerant heating means 750 to provide heat to the refrigerant.

The refrigerant heat-exchanged with water in the refrigerant heating means 750 is introduced into the outdoor unit 100 through the third circulation pipe 716.

Therefore, the refrigerant rapidly cooled via the indoor unit 200 at the extreme cold is heated while passing through the refrigerant heating device 700 to maximize the heat exchange efficiency.

Hereinafter, a case in which the refrigerant flows into the outdoor heat exchanger 180 and the refrigerant heating device 700 is operated to heat the air in the indoor space will be described with reference to FIG. 7.

In this case, the hot water supply valve 582, the heating valve 632, and the hot water exclusive valve 890 are shielded, and the bypass guide valve 144 and the outdoor LEV 102 are shielded.

The hot water pump 840 maintains a stopped state.

The indoor heat exchanger 202 acts as a condenser to warm internal air by heat generation. Since the expansion valves 204 are all open, the refrigerant changed into a liquid phase while passing through the indoor heat exchanger 202 flows into the distributor 300 through the indoor liquid pipe 210 '.

The liquid refrigerant in the distributor 300 is introduced into the outdoor unit 100 through the liquid pipe 210. Since the outdoor LEV 102 is shielded from the refrigerant introduced into the outdoor unit 100, the refrigerant flows into the refrigerant heating device 700 through the first refrigerant pipe 162.

The refrigerant introduced into the refrigerant heating device 700 expands through the heating expansion valve 740, and the heating source 764 provides heat to the water heater 762. Then, this heat heats the water circulating in the heating tank 780 and the water heater 762.

The heated water exchanges heat with the refrigerant via the refrigerant heating means 750 to provide heat to the refrigerant.

The refrigerant heat-exchanged with water in the refrigerant heating means 750 is introduced into the outdoor unit through the third circulation pipe after the refrigerant is heat-changed.

The refrigerant introduced into the outdoor unit passes through the third refrigerant pipe 166, the third check valve 167, and the four-way valve 104, and is supplied to the compressors 120 and 120 ′ through the accumulator 132. Through this process, one heating cycle is formed.

Hereinafter, the outdoor heat exchanger 180 will freeze during the heating operation using the heat pump refrigerant cycle, and the flow of the refrigerant and water during the defrosting operation will be described with reference to FIG. 8.

First, in the heating operation using the heat pump refrigerant cycle, the bypass guide valve 144, the outdoor LEV 102 is opened, the heating expansion valve 740, the overheat cutoff valve 722 and the bypass valve 142 ) Is shielded.

When the heating operation is performed in the state of the above-mentioned piping, the outdoor heat exchanger 180 installed outdoors is frozen and the heat exchange efficiency is lowered, but the defrosting operation is performed to increase the heat exchange efficiency.

At this time, the bypass guide valve 144, the outdoor LEV 102 is shielded, the bypass valve 142 is opened. In addition, the heating source 764 operates to heat the water heating unit 762, and the water circulating in the refrigerant heating device 700 is heated to operate the water heating means 760 as an evaporator.

In addition, since the pressure of the refrigerant measured by the high pressure sensor 126 falls short of the target high pressure, the bypass valve 142 is opened so that the refrigerant flows to the target high pressure.

Looking at the refrigerant flow in this state with reference to Figure 8, some of the refrigerant compressed in the compressor 120 is the bypass valve 142 is open, so the outdoor discharge pipe 148 through the bypass pipe 140 Flows into.

Since the bypass guide valve 144 is shielded, the high temperature and high pressure refrigerant introduced into the outdoor discharge pipe 148 passes through the outdoor heat exchanger 180.

At this time, the outdoor heat exchanger 180 is rapidly defrosted by a high temperature and high pressure refrigerant, the refrigerant is condensed.

Since the condensed refrigerant via the outdoor heat exchanger 180 is passed through the first check valve 199 since the outdoor LEV 102 is shielded.

Then, the refrigerant is introduced into the refrigerant heating device 700 through the first refrigerant pipe 162 and the first circulation pipe 712. The refrigerant introduced into the refrigerant heating device 700 is expanded by the heating expansion valve 740 and then evaporated by being heated by heat exchange with water while passing through the refrigerant heating means 750.

The refrigerant evaporated from the refrigerant heating means 750 flows into the four-way valve 124 through the third circulation pipe 715 and the third refrigerant pipe 166, and then passes through the accumulator 132 and the compressor ( 120).

Meanwhile, the remaining refrigerant, which is not branched into the bypass pipe 140, of the refrigerant compressed by the compressor is passed through the indoor unit 200 and / or the water heat exchanger 400 through the distributor 300.

That is, in the heat pump interlocked hot water circulation system according to the present invention, even when the outdoor heat exchanger 180 is defrosted, air and floor heating of the indoor space may be performed, and hot water may be heated according to the refrigerant flow direction control of the distributor.

Hereinafter, a process of heating by using only a heat pump refrigerant cycle without using the refrigerant heater 700 will be described with reference to FIG. 9.

At this time, the refrigerant heating device 700 is guided to circulate without heating the refrigerant.

To this end, the overheat prevention valve 722, the bypass valve 142 and the heating expansion valve 740 are shielded, and the open / close valve 732, the bypass guide valve 144 and the outdoor LEV 102 are opened. .

Therefore, the refrigerant compressed by the compressor 120 is condensed while the refrigerant flow is controlled in the distributor 300 and passes through the indoor unit 200 and / or the water heat exchanger 400.

Since the condensed refrigerant passes through the distributor 300 and then flows into the outdoor unit 100, the refrigerant introduced into the outdoor unit 100 expands in the outdoor LEV 102 and passes through the outdoor heat exchanger 180. While evaporating while passing through the accumulator 132 and the compressor 120 sequentially.

Meanwhile, some of the refrigerant introduced into the outdoor unit 100 is not introduced into the outdoor heat exchanger 180, but is introduced into the refrigerant heating device 700 through the first refrigerant pipe 162.

Since the refrigerant introduced into the refrigerant heating device 700 is blocked by the overheat prevention tube 720 and the heating expansion valve 740, the refrigerant cannot flow any more and is trapped inside the first circulation tube 712.

On the other hand, the refrigerant evaporated while passing through the outdoor heat exchanger 180 is introduced into the refrigerant heating device 700 through the second refrigerant pipe 164 and the second circulation pipe 714 and then the refrigerant heating means 750. Is passed through without heat exchange.

Thereafter, the refrigerant exits the refrigerant heating device 700 through the third circulation pipe 715, and then passes through the four-way valve 124 and the accumulator 132 through the third refrigerant pipe 166 to the inside of the compressor 120. Inlet and compressed.

Hereinafter, after the heat pump cycle interlocked hot water circulation system is left for a long time, the refrigerant flow in the heating mode using only the refrigerant heating device 700 will be described with reference to FIG. 10.

The bypass guide valve 144 and the outdoor LEV 102 are opened, and the bypass valve 142, the heating expansion valve 740, and the overheat cutoff valve 722 are shielded. The heating source 764 operates to heat the water heater 762.

At this time, the refrigerant compressed by the compressor 120 is introduced into the outdoor unit 100 after passing through the distributor 300 and the indoor unit 200, and passes through the outdoor LEV 102 and the outdoor heat exchanger 180. .

However, when the outdoor heat exchanger 180 is left for a long time, a lot of refrigerant is kept inside. In addition, when only the refrigerant heating device 700 is used as an evaporator without using the outdoor heat exchanger 180, a shortage of refrigerant may occur.

Therefore, the high temperature and high pressure compressed refrigerant is bypassed to the outdoor heat exchanger 180 through the bypass pipe 140 to circulate the refrigerant.

To this end, the bypass guide valve 144 and the outdoor LEV 102 remain open while being shielded to block the refrigerant flow, and the bypass valve 142 is opened.

Therefore, some of the refrigerant compressed by the compressor 120 moves to the outdoor discharge pipe 148 through the bypass pipe 140, and the bypass guide valve 144 and the outdoor LEV 102 are shielded. Therefore, the outdoor heat exchanger 180 passes through the first check valve 199.

After the refrigerant is introduced into the refrigerant heating device 700 through the first refrigerant pipe 162, the refrigerant heating means 750 through the first circulation pipe 712 and the third circulation pipe 715. By heating, it is heated to the refrigerant temperature to maximize the heating efficiency.

Thereafter, the refrigerant flows into the third refrigerant pipe 166 and then passes through the third check valve 167 and sequentially passes through the four-way valve 124, the accumulator 132, and the compressor 120.

On the other hand, some of the refrigerant passing through the third check valve 167 does not go to the four-way valve 124 is branched to pass through the second check valve 165.

Since the refrigerant path guide valve 144 is shielded, the refrigerant is introduced into the refrigerant heating device 700 through the second refrigerant pipe 164.

The refrigerant introduced into the refrigerant heating device 700 flows along the second circulation pipe 714 and is combined with the first circulation pipe 712. The refrigerant is heated while passing through the refrigerant heating means 750 and then the outdoor unit. Flows into.

Hereinafter, the flow of the refrigerant during the cooling operation only by the heat pump refrigerant cycle using the heat pump interlocking hot water circulation system will be described with reference to FIG. 11.

When the heat pump interlocked hot water circulation system is operated in a cooling mode, the refrigerant heater 700 is not used. That is, the refrigerant is controlled not to flow into the refrigerant heating device 700.

Accordingly, the open / close valve 732, the overheat cutoff valve 722, the heating expansion valve 740, the bypass valve 142, and the outdoor LEV 102 are shielded, and the bypass guide valve 144 is opened. .

First, the refrigerant compressed by the high temperature and high pressure in the compressor 120 is guided to the second check valve 165 through the four-way valve 124.

In addition, the refrigerant recovered to the outdoor unit is restricted in flow by the third check valve 167 so that the refrigerant is not introduced into the refrigerant heater 700.

Since the refrigerant passing through the second check valve 165 is shielded from the opening / closing valve 732, the overheat shutoff valve 722, and the heating expansion valve 740, the refrigerant cannot be introduced into the refrigerant heating device 700 and is opened. After passing through the bypass guide valve 144, it is condensed while passing through the outdoor heat exchanger 180.

Thereafter, after passing through the first check valve 199, the distributor 300 is guided to the distributor 300. The distributor controls the refrigerant flow direction to guide the refrigerant to the indoor unit or the water heat exchanger 400.

Then, the refrigerant introduced into the outdoor unit 100 passes through the four-way valve 124 and the accumulator 132 and then flows into the compressor 120 again and is compressed.

Hereinafter, the water flow when the user wants to use hot water quickly by using the hot water forcing device will be described with reference to FIG. 12.

At this time, since the outdoor unit 100, the indoor unit 200, the distributor 300, the water heat exchanger 400 and the water heating device 600 are not used, the inlet shutoff valve 892 and the outlet shutoff valve 894. It will remain open.

The hot water pump 840 and the water heating means 760 are operated.

Thus, the water in the hot water supply pipe 820 is introduced into the water heating means 760 by the pumping action of the hot water pump 840, heated by the heating source 764 and then hot water supply water pipe 820 It is introduced into the hot water supply device 500 along).

In this process, the cold water temperature sensor TH8 and the hot water temperature sensor TH9 continuously measure the temperature of the water heated by the heating source 764 and the water temperature before heating. When the heat source 764 is short of heat for adjusting the required hot water temperature, the heating source 764 supplies a higher heat amount into the hot water supply pipe 820.

The water flow sensor 860 detects the flow rate of the water flowing along the hot water supply pipe 820 to maintain an appropriate level.

Therefore, one side of the hot water supply pipe 820, it is preferable that a separate water supplement 822 for supplementing when the flow rate of the water detected by the water flow sensor 860 is lower than the set water level. Do.

Meanwhile, the water introduced into the hot water supply device 500 is heat-exchanged with the water in the hot water tank 510 and is deprived of heat, and then exits to the outside of the hot water tank 510 through the hot water supply pipe 580. The cooled water exiting the tank 510 is recovered into the water heating means 760 through the hot water supply water pipe 820 since the outlet shutoff valve 894 is opened.

At this time, since the hot water supply valve 582 and the heating valve 632 are shielded, the cooled water exiting the hot water tank 510 does not flow into the water heat exchange device 400, but flows into the water heating means 760. It is cycled.

Due to the circulation of the water it is possible to use the hot water quickly using the hot water forcing device (800).
