It comprises a direction switching valve 160 to be provided to the first heat exchanger 130 or the second heat exchanger 140, wherein the direction switching valve 160 is a general four-sided (4-way valve).

The structure of the heat pump 100 is the same as the existing general heat pump structure, the description of the detailed structure of each configuration is omitted.

Next, the first fluid storage tank 210 and the second fluid storage tank 220 are tanks in which the fluid is stored, and the first fluid flow tube 410 and the second fluid flow tube 420 store the respective fluids. It is a flow pipe for guiding the fluid stored in the tank (210,220) to be heat-exchanged while passing through any one heat exchanger (130,140) corresponding to the fluid storage tank (210,220) again.

Here, the first fluid flow tube 410 is configured to recover the fluid stored in the first fluid storage tank 210 to the first fluid storage tank 210 again after passing through the first heat exchanger 130, The second fluid flow tube 420 is configured to recover the fluid stored in the second fluid storage tank 220 to the second fluid storage tank 220 after passing through the second heat exchanger 140.

In addition, the first embodiment of the present invention further suggests that the replenishment tanks 230 and 240 are connected to the fluid storage tanks 210 and 220, respectively.

In this case, the replenishment tanks 230 and 240 are containers in which the fluid is stored, and are a series of configurations for replenishing the loss of the fluid stored in each of the fluid storage tanks 210 and 220.

That is, when the fluid stored in each fluid storage tank (210,220) flows during the flow, such as leakage, evaporation, or use by the user's needs are considered, the water level in the fluid storage tank (210,220) compared to the preset water level When low, the fluid stored in the replenishment tanks 230 and 240 may be provided into the fluid storage tanks 210 and 220.

Next, the auxiliary heat exchanger 300 is a series of components for heat-exchanging the fluid stored in the first fluid storage tank 210 and the fluid stored in the second fluid storage tank 220.

In the first embodiment of the present invention, the auxiliary heat exchanger 300 includes a third fluid flow tube 310, a third circulation pump 320, a fourth fluid flow tube 330, and a fourth circulation pump 340. ), And proposes that the heat exchanger 350 is configured.

In this case, the third fluid flow tube 310 is a conduit configured to circulate some of the fluid stored in the first fluid storage tank 210 in a state in which both ends thereof are connected to the first fluid storage tank 210. The circulation pump 320 is a pump for circulating fluid along the third fluid flow tube 310, and the fourth fluid flow tube 330 is connected to the second fluid storage tank 220 at both ends thereof. In addition to being a conduit configured to circulate some of the fluid stored in the fluid storage tank 210, the fourth circulation pump 340 is a pump to circulate the fluid along the fourth fluid flow pipe 330.

As described above, the auxiliary heat exchanger 300 has a disadvantage in that required power of the compressor 120 is gradually increased as the temperature of the fluid stored in the second fluid storage tank 220 is continuously increased during the cooling operation. As the temperature of the fluid stored in the second fluid storage tank 220 continuously decreases, problems such as the operation of the compressor 120 due to the lack of the evaporation heat source of the second heat exchanger 140 serving as the evaporator may occur. It is a configuration that can be prevented.

At this time, the air-conditioner 600 is configured to pass through the first heat exchanger 130 of the first fluid flow pipe 410, the pipeline to be recovered to the first fluid storage tank 210 while cooling or heating It is installed in the space that needs it.

Of course, the heat pump 100 itself may be divided into an outdoor unit and an indoor unit, and the indoor unit may be used as an air conditioner, but in this case, the problem that the size of the heat pump 100 itself is inevitably increased and that the indoor unit may be composed of only one unit. This is not preferable because of this.

In addition, in the first embodiment of the present invention is provided on the pipeline between the first heat exchanger 130 and the air conditioner 600 of the first fluid flow pipe 410 and the fluid passing through the corresponding portion during the heating operation It is proposed that the auxiliary heater 700 for heating is further included.

The auxiliary heater 700 is to improve the operating efficiency of the heat pump 100 during the winter, the fluid flowing along the first fluid flow pipe 410 in the initial operation of the heat pump 100 By heating to enable heating through the air conditioner (600) until the heat pump 100 performs a stable operation, or if hot water is required if the high temperature hot water additionally by heating the hot water heated by the heat pump 100 It serves to help the hot water at the desired temperature.

In particular, the auxiliary heater 700 is composed of a Silicon Control Rectifier (SCR) device having a proportional control function so that the output is controlled differently according to the temperature of the fluid flowing along the first fluid flow pipe 410 More preferred.

In the following, the operation of the boiler combined heat pump system according to the first embodiment of the present invention configured as described above will be described in more detail.

First, Figure 1 attached shows a process during the cooling operation of the boiler combined heat pump system.

As can be seen through this, when an operation for cooling operation is made, the first heat exchanger 130 constituting the heat pump 100 serves as an evaporator, and the second heat exchanger 140 serves as a condenser. The direction switching valve 160 serves to guide the refrigerant passing through the compressor 120 to the second heat exchanger 140.

That is, the refrigerant flowing along the refrigerant pipe 110 is compressed by the operation of the compressor 120, and the compressed refrigerant is provided to the second heat exchanger 140 by the guidance of the direction switching valve 160. It is condensed, continuously expanded through the expander 150, and then evaporated through the first heat exchanger 130, and then the circulation flowing into the compressor 110 is repeated.

In addition, when the above-described series of processes are performed, the first fluid is driven by the first circulation pump 510 and the second circulation pump 520 installed in the first fluid flow tube 410 and the second fluid flow tube 420. The fluid stored in the storage tank 210 and the second fluid storage tank 220 is continuously circulated.

That is, some of the fluid stored in the first fluid storage tank 210 by the driving of the first circulation pump 510 circulates through the first fluid flow pipe 410, and by the driving of the second circulation pump 520 Some of the fluid stored in the second fluid storage tank 220 is to circulate the second fluid flow pipe 420.

At this time, the fluid circulating in the first fluid flow tube 410 is cooled while being heat-exchanged with the first heat exchanger 130 in the process of passing through the first heat exchanger 130 and then introduced into the first fluid storage tank 210. The fluid circulating in the second fluid flow tube 420 is heated while being heat-exchanged with the second heat exchanger 130 in the process of passing through the second heat exchanger 140, and then flows into the second fluid storage tank 220. do.

In addition, the air conditioner 600 cools the space in which the device is installed through heat exchange with the cold fluid while passing through the first heat exchanger 130.

If the level of the fluid stored in the first fluid storage tank 210 or the second fluid storage tank 220 is lower than the preset level during the above-described series of processes, the corresponding fluid storage tanks 210 and 220 may be used. Replenishment of the fluid to the loss through the replenishment tank (230,240) connected with this, the boiler combined heat pump system according to the first embodiment of the present invention can continuously perform a smooth operation.

Next, Figure 2 attached shows a process during heating operation using the boiler combined heat pump system according to the first embodiment of the present invention.

As can be seen through this, when an operation for heating operation is made, the first heat exchanger 130 constituting the heat pump 100 serves as a condenser, and the second heat exchanger 140 serves as an evaporator. In addition, the direction switching valve 160 serves to guide the refrigerant passing through the compressor 120 to the first heat exchanger 130.

That is, the refrigerant flowing along the refrigerant pipe 110 is compressed by the operation of the compressor 120, and the compressed refrigerant is provided to the first heat exchanger 130 by the guidance of the direction switching valve 160 to condense. Then, it is continuously expanded while passing through the expander 150, and then evaporated through the second heat exchanger 140, and then the circulation flowing into the compressor 120 is repeated.

However, during the heating operation of the winter as described above, due to the low temperature of the outside air, the condensation operation of the refrigerant by the first heat exchanger 130 may not be performed quickly. The operation is performed.

Accordingly, in the first embodiment of the present invention, when the heating operation is performed in winter, the operation of the circulation pumps 510 and 520 and the operation of the auxiliary heater 700 are prioritized before the operation of the heat pump 100 is performed. It suggests that it consists of.

That is, when the heating operation is performed, the fluid is circulated through the fluid flow pipes 410 and 420 while the circulation pumps 510 and 520 are operated, and the first fluid flow pipe 410 is performed while the auxiliary heater 700 is operated. The fluid circulated along is heated instantaneously.

As a result, the air provided through the air conditioner 600 is provided in a state in which the set heating temperature is reached, thereby preventing the problem that the initial heating is not performed quickly and the cold air is provided.

In addition, the fluid circulating along the first fluid flow tube 410 as described above serves to increase the temperature in the first fluid storage tank 210 until the operation of the heat pump 100 is stabilized. Together, the temperature of the first heat exchanger 130 also increases.

In particular, when the auxiliary heater 700 is a SCR (Silicon Control Rectifier) device having a proportional control function so that the output is controlled differently according to the temperature of the fluid is stable as the output is adjusted in proportion to the set temperature Heating and power usage efficiency can be improved.

Therefore, the heat pump 100 has a time when the operation is stabilized as the operation is started in the state in which the optimum operating conditions are reached (for example, the state of the fluid temperature of the upper side of the first fluid storage tank reached 20 ℃) This can be shortened so that the driving efficiency can be further improved.

When the heat pump 100 is operated under the optimum conditions according to the operation of the auxiliary heater 700, the operation of the auxiliary heater 700 is stopped and the fluid circulates through the first fluid flow tube 410. Is heated while being heat-exchanged with the first heat exchanger 130 in the process of passing through the first heat exchanger 130, and then flows into the first fluid storage tank 210 and circulates the second fluid flow pipe 420. In the process of passing through the second heat exchanger 140 is cooled while being heat-exchanged with the second heat exchanger (! 40) is introduced into the second fluid storage tank 220.

In addition, the air conditioner 600 heats the space where the corresponding device is installed through heat exchange with the heated fluid while passing through the first heat exchanger 130.

In addition, during the above-described series of processes, the fluid and the second fluid stored in the first fluid storage tank 210 by the operation of the third circulation pump 320 and the fourth circulation pump 340 constituting the auxiliary heat exchanger. Fluids stored in the storage tank 220 heat exchange with each other.

At this time, the fluid in the second fluid storage tank 220 is increased in temperature as it is heat-exchanged with the fluid in the first fluid storage tank 210, the fluid is heated to this temperature is the heat pump 100 By operating the second heat exchanger 140 as a heat source that can be maintained at a temperature of about 15 to 20 ℃, the operation such as the operation of the compressor 120 is stopped even if the outdoor temperature is extremely low, such as winter Improper problem is prevented from occurring, and stable heat pump 100 can be operated.

In addition, defrosting is possible even if the defrosting operation of the second heat exchanger 140 serving as an evaporator is performed by heat exchange between the fluid storage tanks 210 and 220 using the auxiliary heat exchanger 300. Have too.

In addition, when the level of the fluid stored in the first fluid storage tank 210 or the second fluid storage tank 220 is lower than a predetermined level while the above-described series of processes are performed, the fluid storage tanks 210 and 220. Replenishment of the fluid to the loss is made through the replenishment tanks 230 and 240 connected with the above, and thus, the combined boiler type heat pump system according to the second embodiment of the present invention can continuously perform a smooth operation.

On the other hand, the auxiliary heater 700 during each of the above-described process does not necessarily have to be stopped when the operation of the heat pump 100 is performed.

That is, the auxiliary heater 700 serves to assist the operation at the initial operation of the heat pump 100 by setting the heat pump 100 to start operation even when the heat pump 100 does not reach the optimum operating condition. In addition, the operation of the auxiliary heater 700 is performed at the same time as the start of the operation of the heat pump 100 until the operation of the heat pump 100 is stabilized by the operation of the auxiliary heater 700 described above. It can also be controlled to enable heating. In addition, even when hot water (eg, hot water of 55 ° C. or more) is required according to a user's need, additional heating of the fluid by the auxiliary heater 700 may be performed.

On the other hand, Figures 3 and 4 attached to show a boiler combined heat pump system according to a second embodiment of the present invention.

As can be seen from this, in the second embodiment of the present invention, as long as the fluid stored in one of the fluid storage tanks 220 is different from the auxiliary heat exchanger 300 which exchanges the fluids in the fluid storage tanks 210 and 220. It is suggested that the heat exchange while passing through the fluid storage tank 210.

That is, the auxiliary heat exchanger 300 according to the second embodiment of the present invention receives a fluid from the second fluid storage tank 220 and passes through the inside of the first fluid storage tank 210 (hereinafter, “the 5 fluid flow tube ”) and a circulation pump (hereinafter referred to as a“ 5th circulation pump ”) 370 for allowing the fluid to circulate along the fifth fluid flow tube 360, The heat exchange between the fluid storage tanks 210 and 220 may be performed so that a separate defrosting operation may be omitted during the winter and the heat source may be assisted for the evaporation operation of the second heat exchanger 140.

At this time, the portion of each of the fifth fluid flow tube 360 passing through the first fluid storage tank 210 is preferably configured to further improve the heat exchange efficiency by, for example, in the form of a coil.

Of course, although not shown, the fifth fluid flow pipe 360 includes a pipe passing through the interior of both the first fluid storage tank 210 and the second fluid storage tank 220, and the fifth fluid flow pipe ( The inside of the fluid storage tanks 210 and 220 by the fluid circulated along the conduit along the fifth fluid flow pipe 360 is configured to flow a fluid having excellent heat transfer, such as a refrigerant flow inside the 360. It may be configured to be heat exchanged.
