Description

Hot water generating apparatus using heat pump

The present invention relates to a hot water generator, and more particularly to a heat pump type hot water generator for generating hot water using a heat pump.

1 shows a configuration of a heat pump type hot water generator according to the prior art. Such a hot water generator is used in a bathroom or inn and industrial facilities that use a lot of hot water.

According to this, the compressor (1), the first heat exchanger (3), the expansion valve (5) and the second heat exchanger (6) are connected by a connecting pipe (7) so that the working fluid flows therebetween to make heat exchange. do.

At this time, the first heat exchanger (3) is connected to the hot water tank (8) so that the water of a relatively low temperature from the hot water tank (8) is supplied to the first heat exchanger (3) to exchange heat with the working fluid to become hot water It is delivered to the hot water tank (8) again. In addition, a conduit 10 is connected to the second heat exchanger 6 so that heat for evaporation of the working fluid is supplied from the waste hot water in which the hot water of the hot water tank 8 is used. Here, the second heat exchanger is generally a cell and tube method.

Reference numeral 2 is an oil separator for separating oil in the working fluid, and 4 is a receiver for allowing only the working fluid in the liquid state to be delivered to the expansion valve 5.

In the prior art having such a configuration, a high temperature, high pressure gaseous working fluid compressed by the compressor 1 is supplied to the first heat exchanger 3 to transfer heat to the cold water delivered from the hot water tank 8 to supply hot water. Make it up At this time, the working fluid is condensed into a liquid state of low temperature and high pressure.

The working fluid condensed as described above is transferred to the receiver 4, and only the working fluid in the liquid state is transferred to the expansion valve 5 so as to be easily evaporated in the second heat exchanger. It becomes the liquid state of low temperature low pressure. The expanded working fluid receives the heat of the waste hot water from the second heat exchanger 6 and evaporates to a relatively high temperature and low pressure gas state.

However, the prior art as described above has the following problems.

First, low temperature waste water is supplied into the second heat exchanger 6 of the cell-and-tube type to provide heat for evaporation of the working fluid. Therefore, the second heat exchanger 6 is easily contaminated by foreign matter mixed with the waste hot water, which causes frequent problems of cleaning.

In the second heat exchanger 6, the entire cycle can be operated only when the working fluid receives heat from the waste hot water. However, since the waste hot water is not always supplied in a constant amount, it is not always possible to supply as much heat as necessary to the second heat exchanger 6. Therefore, there is a problem that the operation of the cycle is not smooth.

In particular, at the first start of the cycle, since there is no waste hot water and no heat exchange occurs in the second heat exchanger 6, it is difficult to start the cycle itself. In order to solve this problem, in the related art, a separate boiler is used to heat the water in the hot water tank 8 to provide hot water, and when the hot water is used to generate waste hot water, the system operates normally. Therefore, the prior art has a problem that a separate boiler must be used for the start of the cycle.

In the prior art, when the temperature of the cold water delivered to the first heat exchanger 3 is relatively low, the temperature of the hot water discharged and delivered to the hot water tank 8 is also relatively low. This is because the cycle operates with the pressure of the working fluid passing through the first heat exchanger 3 not maintained at the set value.

Therefore, an object of the present invention is to solve the problems of the prior art as described above, to improve the operation reliability of the hot water generator.

Another object of the present invention is to provide a hot water generator that is not affected by the supply amount of waste hot water.

Still another object of the present invention is to provide a hot water generator that can always obtain a constant hot water temperature.

According to the present invention having such a configuration there is an advantage that the operation of the hot water generating device more smoothly and durability can be supplied more stable supply of hot water.

Hereinafter, a preferred embodiment of a heat pump type hot water generator according to the present invention as described above will be described in detail with reference to the accompanying drawings.

2 is a block diagram of a preferred embodiment of the warm water generator according to the present invention. According to this, the present embodiment includes a configuration for generating hot water in the compressor 10, the first heat exchanger 20, the expansion valve 30 and the second heat exchanger 40 constituting the heat pump cycle. It is configured by.

The compressor 10 compresses the working fluid into a gaseous state of high temperature and high pressure. The oil separator 12 is installed in connection with the outlet of the compressor 10. The oil separator 12 separates the oil of the compressor 10 mixed in the working fluid.

The first heat exchanger 20 is installed in connection with the outlet of the compressor 10. The first heat exchanger 20 is a portion for performing heat exchange between the working fluid and water to transfer the heat of the working fluid to water to generate hot water. In this process, the working fluid is condensed into a liquid state of high temperature and high pressure. It is preferable that the plate heat exchanger is used as the first heat exchanger 20.

An auxiliary heat exchanger 25 is installed to be connected in parallel with the first heat exchanger 20 to receive the working fluid delivered from the compressor 10. A control valve 22 is installed at the inlet side of the auxiliary heat exchanger 25 to control the supply of the working fluid to the auxiliary heat exchanger 25. The control valve 22 selectively supplies the working fluid from the compressor 10 to the auxiliary heat exchanger 25. The auxiliary heat exchanger 25 transfers heat to water supplied from a separate external water tank 60 to supply heat for evaporation of the working fluid in the second heat exchanger 40.

The heat exchanger 28 performs heat exchange between the working fluid from the first heat exchanger 20 and the auxiliary heat exchanger 25 and the working fluid delivered to the compressor 10. At this time, heat is transferred from the relatively high temperature working fluid, which is the liquid state from the heat exchangers 20 and 25, to the working fluid delivered to the compressor 10, and the liquid state is operated in the working fluid entering the compressor 10. It makes the fluid gaseous.

The receiver 29 collects only the working fluid in the liquid state from the working fluid from the heat receiver 28 and delivers it to the expansion valve 30. The expansion valve 30 expands the working fluid to a relatively low temperature and low pressure and makes it easy to evaporate in the second heat exchanger 40.

In the second heat exchanger 40, the working fluid is evaporated by receiving heat from the water passing through the auxiliary heat exchanger 25. Therefore, heat for evaporation of the working fluid is supplied from the auxiliary heat exchanger 25. Through this process, in the second heat exchanger 40, the working fluid becomes a gas state of relatively low temperature and low pressure. The second heat exchanger 40 has an inlet connected to the expansion valve 30 and an outlet connected to the heat exchanger 28.

In the present invention, the auxiliary heat exchanger 25 is used to supply heat for evaporation of the working fluid in the second heat exchanger 40. That is, the external water tank 60 and the auxiliary heat exchanger 25 are connected, so that the water supplied from the external water tank 60 receives heat from the working fluid in the auxiliary heat exchanger 25 to a relatively high temperature. . Water at a relatively high temperature is supplied to the second heat exchanger 40 to supply heat for evaporation of the working fluid, and to be brought to a relatively low temperature and then to the external water tank 60.

On the other hand, hot water is generated in the first heat exchanger (20). Cold water is supplied from the water supply source 52 to the first heat exchanger 20. At this time, the pump (54, 54 '), the valve (55, 55') and the check valve (56, 56 ') to adjust the amount of cold water supplied from the water supply source 52 to the first heat exchanger (20) It is provided. The pumps 54 and 54 ', the valves 55 and 55' and the check valves 56 and 56 'are connected in parallel.

Normally, only one pump 54, a valve 55 and a check valve 56 are used, and when the first heat exchanger 20 is overheated, all the pumps 54, 54 ', the valves 55, 55' ) And check valves 56, 56 ′ to supply relatively large amounts of cold water to the first heat exchanger 20.

The pumps 54, 54 'here provide the driving force for water supply, the valves 55, 55' adjust the amount of water supply, and the check valves 56, 56 'prevent the water from flowing back. Of course, the number of pumps 54 and 54 ', valves 55 and 55' and check valves 56 and 56 'varies depending on the design conditions. In addition, it is also possible to adjust the amount of cold water supplied using only one pump 54 valve 55 and check valve 56 having a relatively large capacity.

For reference, the outlet of the water supply source 52 is directly connected to the hot water tank 50, and parts such as the pumps 54 and 54 ′ are installed at the outlet of the hot water tank 50 so that Water may be configured to be supplied to the first heat exchanger 20 to be hot water and then transferred to the hot water tank 50 again.

On the other hand, the water supplied from the auxiliary heat exchanger 25 to provide heat for the evaporation of the working fluid in the second heat exchanger 40 is provided in the external water tank (60). The external water tank 60 is installed outdoors. Therefore, the amount of heat received from the auxiliary heat exchanger 25 varies depending on the environment of the space in which the external water tank 60 is installed. For example, when the external water tank 60 is installed in a high temperature environment, the auxiliary heat exchanger 25 may operate only the relatively small amount of the working fluid by operating the control valve 22. In this case, since the temperature of the external water tank 60 is relatively high in summer in Korea, the amount of the working fluid delivered to the auxiliary heat exchanger 25 may be reduced by operating the control valve 22.

Next, pressure control valves 70 and 70 'are installed at one side of the conduit 80 connecting the compressor 10, the first heat exchanger 20, the expansion valve 30, and the second heat exchanger 40. . The pressure control valve (70, 70 ') is to ensure that the pressure of the working fluid must be a certain value or more to flow along the inside of the conduit (80). If the pressure of the working fluid does not reach the set value, the working fluid does not flow through the conduit 80 by the pressure regulating valves 70 and 70 '. The compressor 10 continues to operate to allow the working fluid to flow through the conduit 80 when the working fluid reaches the set pressure.

By installing the pressure control valves 70 and 70 'as described above, the working fluid can be supplied to the first heat exchanger 20 while maintaining the set pressure at all times, and receives heat from the working fluid. Hot water discharged from the heat exchanger 20 will always have a set temperature value.

Hereinafter, the operation of the heat pump type hot water generator according to the present invention having the configuration as described above will be described.

When the hot water generator of the present invention is started for the first time, the cycle starts to operate as the working fluid becomes a gas of high temperature and high pressure by compression in the compressor 10. At this time, the working fluid by the pressure control valve (70, 70 ') does not flow in the conduit (80) until the set pressure. Only when the pressure is set is the working fluid begins to flow through the conduit (80). Here, the pressure control valve 70 installed on the high pressure side is set to open only when the pressure is relatively high, and the pressure control valve 70 'installed on the low pressure side is set to a relatively low pressure.

The working fluid from the compressor 10 passes through the oil separator 12 and the oil is separated and only the working fluid flows. In addition, the high temperature and high pressure working fluid is supplied to the first heat exchanger 20 and the auxiliary heat exchanger 25 to exchange heat with water, respectively, to generate hot water in the first heat exchanger 20, and then to the auxiliary heat exchanger 25. ) Supplies the amount of heat required for evaporation of the working fluid in the second heat exchanger 40 to the working fluid.

Here, the amount of working fluid supplied to the auxiliary heat exchanger 25 is controlled by the control valve 22. In particular, the amount of working fluid supplied to the auxiliary heat exchanger 25 is adjusted according to the environment in which the external water tank 60 is installed. In the summer of Korea, since the temperature of the external water tank 60 is relatively high, the amount of heat to be transmitted is relatively small. In winter, since a relatively large amount of heat must be transmitted, a relatively large amount of working fluid is supplied to the auxiliary heat exchanger 25 through the control valve 22.

The working fluid heat-exchanged in the first heat exchanger 20 is in a liquid state of relatively low temperature and high pressure. The working fluid leaving the first heat exchanger 20 is delivered to the liquid heat exchanger 28. In the liquid heater 28, the working fluid before entering the compressor 10 and the working fluid exiting the first heat exchanger 20 exchange heat. In this way, heat is transferred to the working fluid entering the compressor 10 so that the whole becomes gaseous.

The working fluid exiting the heat receiver 28 is delivered to the receiver 29, and only the working fluid in the liquid state is transferred to the expansion valve 30 from the receiver 29. The expansion valve 30 expands the working fluid so as to facilitate evaporation in the second heat exchanger 40.

The working fluid expanded in the expansion valve 30 enters the second heat exchanger 40. The working fluid entering the second heat exchanger 40 is supplied with heat from the working fluid in the auxiliary heat exchanger 25 and is supplied with heat from water having a predetermined temperature to evaporate. The water, which is hot water in the subsidiary heat exchanger 25, is exchanged in the second heat exchanger 40 to a relatively low temperature, and then transferred to the external water tank 60.

Then, the working fluid from the second heat exchanger 40 passes through the liquid heat exchanger 28 and receives heat from the working fluid exiting the first heat exchanger 20 so as to be completely in a gaseous state. Is delivered to.

As described above, in the present invention, the heat exchange between the working fluid in the liquid heater 28 is performed, and the compression efficiency of the compressor 10 is increased by entering the gas working fluid into the compressor 10.

Meanwhile, in the present invention, the water in the external water tank 60 is exchanged with the working fluid in the auxiliary heat exchanger 25 to make a relatively high temperature, and the amount of heat of the water is evaporated in the second heat exchanger 40. Use for In this case, a cell and tube type heat exchanger or a plate heat exchanger may be used as the second heat exchanger 40. Since the clean water is used, the second heat exchanger 40 may not be frequently cleaned.

In addition, water providing heat for evaporation of the working fluid in the second heat exchanger 40 may always be constantly supplied. This is because the auxiliary tank 60 is always provided with a certain amount of water or more, and can receive a desired amount of heat from the auxiliary heat exchanger 25.

As such, when a constant amount of heat can be supplied to the second heat exchanger 40 at all times, the working fluid is uniformly evaporated in the second heat exchanger 40, thereby facilitating the operation of the entire hot water generator.

Since the auxiliary heat exchanger 25 is supplied with a working fluid compressed in the compressor 10 to become a gaseous state of high temperature and high pressure and supplies heat to water, it is necessary to heat the water with a separate heat source at the first startup. There will be no.

In addition, since the pressure control valves 70 and 70 'are used as described above, the temperature of the hot water generated in the first heat exchanger 20 is always regardless of the temperature of the water initially input to the first heat exchanger 20. It becomes constant. This is because the pressure regulating valve 70 maintains the pressure of the working fluid in the first heat exchanger 20 at a predetermined value at all times. That is, since the working fluid is always maintained at the set pressure in the first heat exchanger 20 is discharged from the first heat exchanger 20 as long as the heat exchange is performed in an optimal state and water of extremely low temperature is not input The temperature of the hot water will maintain the set value.

In the present invention, the water in the external water tank 60 receives heat from the auxiliary heat exchanger 25 without using waste hot water so as to supply heat required for evaporation of the working fluid in the second heat exchanger 40. Therefore, since the waste water is not used as in the prior art, the maintenance of the second heat exchanger 40 becomes easier.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.

For example, the hot water generated in the present invention may be used for heating, or may be used as a cooling and heating device by using the heat exchanged water in the second heat exchanger for cooling.

Heat pump type hot water generator according to the present invention as described in detail above has the following effects.

First, in the present invention, since the water for evaporation of the working fluid in the second heat exchanger uses clean water supplied from the external water tank, the maintenance cost of the hot water generator is reduced. In particular, since heat is transmitted using clean water supplied from an external water tank without using waste water, durability of the second heat exchanger is increased.

In addition, since the water supplied from the external water tank supplies the required amount of heat from the second heat exchanger, it is possible to supply a constant amount of heat to the second heat exchanger at all times, so that the working fluid evaporates in the second heat exchanger smoothly so that the operation of the entire hot water generator is smooth. Done.

In addition, the pressure control valve is installed in the conduit so that the operating fluid flows only when the pressure of the working fluid is above a certain value so that the hot water generating device is operated so that the temperature of the hot water generated in the first heat exchanger can always be maintained at a constant value. It is possible to supply hot water stably.
