Description

Temperature sensor of unitary air conditioner system

The present invention relates to a unitary air conditioner, and more particularly, to a temperature sensor capable of measuring the external temperature more closely.

The present invention relates to a unitary air conditioner, and more particularly, to a temperature sensor capable of measuring the external temperature more closely.

In general, a unitary air condition system creates cold or hot air in one place using air conditioning equipment provided in basements of factories, offices, hotels, and homes, and this is a duct equipped with walls in buildings, etc. It is a kind of centralized cooling and heating system that is transported and supplied to individual spaces through the air conditioning system.

Even if it is a kind of centralized cooling and heating system, the composition is not uniform and varied because the outdoor temperature varies by region. In particular, when the outdoor temperature is low, such as in North America or Canada, it may be unreasonable or inefficient to heat the room using only a heat pump system. This is because the outdoor temperature is relatively low, so it is difficult to obtain heat from the outdoor air. In this case, the performance (compression ratio, etc.) of the compressor included in the heat pump should be higher than the compressor included in the heat pump in other regions.

Accordingly, in regions such as North America described above, heating may be performed by providing not only a heat pump but also a separate configuration for heating an indoor space. That is, when the outdoor temperature is higher, the indoor space can be heated through the heat pump, but when the outdoor temperature is lower, the indoor space can be heated through a separate configuration.

A separate configuration may be a furnace, and in the case of a furnace, it is a device that generates heat by burning fossil fuels or using electricity. For example, a fireplace can supply heat to an indoor space through fossil fuels. In addition, in recent years, it is possible to heat an indoor space through gas fuel, and this may be referred to as a gas furnace.

1 is a conceptual diagram of a unitary air conditioning system 100.

Referring to FIG. 1, the unitary air conditioning system 100 may be divided into an indoor 150 and an outdoor air-conditioning target.

A controller 110 and an indoor heat exchanger 120 for setting and controlling air conditioning may be provided in the room 150 to be subjected to air conditioning. The controller 110 may receive an appropriate temperature of the room 150 to be subjected to air conditioning. In addition, the indoor heat exchanger 120 may mean a heat exchanger installed in the indoor 150, and pleasant air passing through the indoor heat exchanger 120 may flow into the indoor 150.

In addition, in general, the gas furnace 130 installed in the basement (not shown) of the room 150 is a configuration capable of transferring heat to the room by burning gas fuel, as described above.

Meanwhile, components installed outdoors may be operated to introduce comfortable air into the indoor 150, and an outdoor unit 140 may be installed outdoors.

The outdoor unit 140 may be included in a heat pump. Accordingly, the heat pump is operated according to the outdoor temperature so that the outdoor unit 140 is operated or the gas furnace 130 is operated to supply appropriate air to the indoor 150.

Accordingly, in this way, the unitary air conditioner system 100 may include a configuration for supplying appropriate air to the indoor 150. The gas furnace 130 may be operated with a lower outdoor temperature, or the outdoor unit 140 included in the heat pump may be operated with a higher outdoor temperature.

However, as described above, it may be desirable to operate the outdoor unit 140 and the gas furnace 130 of the heat pump alternatively. This is because driving both of the two components 130 and 140 under the same purpose of heating the room 150 may cause inefficiency.

However, when the outdoor temperature is around a set temperature that determines the alternative operation of the gas furnace 130 and the outdoor unit 140, switching of the operation may be problematic. That is, the operation of the gas furnace 130 is stopped and the outdoor unit 140 is operated, or the operation of the outdoor unit 140 is stopped and mode switching in which the gas furnace 130 is operated often occurs, so that the unitary air conditioner system ( 100) can cause inefficiency.

Accordingly, an object of the present invention is to provide a sensing unit that prevents switching due to an error in temperature measurement by more closely measuring the outdoor temperature even when the outdoor temperature is around a set temperature.

2 is a block diagram schematically showing a heating operation.

2(a) is a block diagram showing a heating operation by a heat pump, and FIG. 2(b) is a block diagram showing a heating operation by a gas furnace.

As described above, the gas furnace 130 and the outdoor unit 140 of the heat pump may be selectively operated according to a set temperature. More specifically, when the outdoor temperature is lower than the set temperature and the external load is relatively large, the gas furnace 130 may operate to supply heat to the indoor 150. In addition, when the outdoor temperature is higher than the set temperature and the external load is relatively small, the outdoor unit 140 included in the heat pump may operate to supply heat to the indoor 150.

As shown in FIG. 2A, when the outdoor temperature is higher than the set temperature, the outdoor unit 140 of the heat pump is operated to supply heat to the indoor 150. In this case, the refrigerant flowing through the outdoor unit 140 may exchange heat with the outside. The fan 149 provided for smooth heat exchange of the refrigerant may be installed inside the outdoor unit 140, and may be installed outside the outdoor unit 140 separately from the outdoor unit 140. The fan 149 causes forced convection, so that heat exchange between outdoor air and refrigerant can be performed more efficiently.

The refrigerant heat-exchanged with outdoor air may move to the heat transfer unit 170 along the pipe 147. The heat transfer unit 170 may be installed in the room 150, and the room 150 may receive heat from the heat transfer unit 170.

As shown in FIG. 2B, when the outdoor temperature is lower than the set temperature, the gas furnace 130 is operated to supply heat to the indoor 150. In this case, the outdoor unit 140 may not operate, and the refrigerant may also not flow along the pipe 147.

The gas furnace 130 may receive gas fuel, burn it, and generate heat. In addition, the gas furnace 130 may further include a furnace fan 131 and a furnace heat exchange unit 133 to transfer the generated heat to the room 150.

The furnace heat exchange unit 133 may transfer generated heat to the heat transfer unit 170, and the furnace fan 131 may help heat transfer of the furnace heat exchange unit 133. That is, heat generated in the gas furnace 130 by the operation of the furnace fan 131 may be more efficiently transferred to the heat transfer unit 170. In addition, the heat transfer unit 170 may provide heat to the room 150.

A set temperature, which is a reference for the alternative operation of the gas furnace 130 and the outdoor unit 140, may be set by a user. Or, it can be set automatically.

Also, the set temperature may be stored in the microcomputer 180. Accordingly, when the outdoor temperature is measured by the sensing unit 160 to be described later, the micom 180 may receive the measured temperature and alternatively operate the gas furnace 130 or the outdoor unit 140. Accordingly, the micom 180 may perform the role of the controller 180.

However, when the outdoor temperature measured by the sensing unit 160 is in the vicinity of the set temperature, switching of operation may be problematic. For example, when the outdoor temperature continuously fluctuates based on the set temperature, the operation may be switched whenever the measured outdoor temperature exceeds the set temperature.

Accordingly, it is possible to prevent frequent switching of driving by setting the buffer temperature.

3 is a conceptual diagram of a buffer temperature.

As described above, when the measured outdoor temperature is in the vicinity of the set temperature, frequent operation switching may be a problem. Therefore, it is important to set the balance point, but it will be seen that it is also important to set the buffer temperature. The buffer temperature may be defined as a temperature at which switching of driving is performed only when the measured outdoor temperature exceeds a certain level even if the measured outdoor temperature exceeds the set temperature BP to prevent frequent switching of driving.

That is, when the buffer temperature is set, the operation can be switched only after passing the set temperature BP and then reaching the buffer temperature. Based on the two dotted lines, the lowermost area is the furnace zone (FZ), the area between the two dotted lines is the buffer zone (BZ), and the uppermost area is the heat pump zone (HZ).

A criterion for dividing the furnace zone FZ and the buffer zone BZ may be a set temperature BP. That is, the area above the set temperature BP may be the buffer zone BZ and the heat pump zone HZ, and the area below the set temperature BP may be the furnace zone FZ. .

Considering the case where the measured outdoor temperature is lower than the set temperature (BP) and located in the furnace zone (FZ), the operation of the gas furnace 130 stops immediately when the measured outdoor temperature reaches the set temperature (BP). And the outdoor unit 140 may not start. When the measured outdoor temperature reaches the set temperature BP and rises by the buffer temperature above that, the operation of the gas furnace 130 is stopped and the outdoor unit 140 may start.

Conversely, if the measured temperature gradually decreases, even if the measured outdoor temperature is lower than the temperature obtained by adding the buffer temperature to the set temperature (BP), the operation of the outdoor unit 140 is stopped and the operation of the gas furnace 130 is not started. I can. That is, when the measured outdoor temperature is in the heat pump zone (HZ), the operation of the outdoor unit 140 is stopped and the operation of the gas furnace 130 may be started when the measured outdoor temperature is lower than the set temperature (BP). .

Naturally, it is possible to set the buffer zone (BZ) even when it passes from the hip pump zone (HZ) to the furnace zone (FZ), and in this case, the operation of the outdoor unit 140 must be further reduced by the buffer temperature from the set temperature (BP). It may be stopped and the operation of the gas furnace 130 may be started. In addition, when passing from the furnace zone FZ to the heat pump zone HZ, when only the set temperature BP passes, the operation of the gas furnace 130 may be stopped and the outdoor unit 140 may be started.

In the end, it can be seen that the setting of the set temperature BP is also important, but the setting of the buffer temperature is also important. This is because the operation can be switched according to the buffer temperature.

When the buffer temperature is set relatively small, the operation can be switched within a short time. In addition, when the buffer temperature is set relatively large, the overall efficiency of the system may be impaired because operation is not switched even after a long period of time.

4 is a graph showing switching of driving according to outdoor temperature.

The graph shown in FIG. 4 shows the result of observing approximately 150 minutes with a set temperature (BP) of -6.67 degrees and a buffer temperature of 2.78 degrees.

In this case, when the outdoor temperature falls below -6.67 degrees, the gas furnace 130 is operated, and when the temperature reaches -3.89 degrees or more, the operation of the gas furnace 130 is stopped and the outdoor unit 140 is operated. Meanwhile, -3.89 degrees is the sum of the buffer temperature from the set temperature (BP).

The straight portion A shown at the top of the vertical axis indicates whether the outdoor unit 140 of the heat pump is operating. When the number 2 on the left vertical axis is 2, the operation of the outdoor unit 140 is stopped, and when the number 6 on the left vertical axis is the number 2 on the left vertical axis, it is notified that the operation of the outdoor unit 140 is started. When the outdoor unit 140 is operated, a compressor (not shown) included in the outdoor unit 140 may be operated.

The straight portion C shown at the bottom of the vertical axis indicates whether the gas furnace 130 is operated. If the number 1 on the left vertical axis is 1, the outdoor unit 140 is operated and the gas furnace 130 does not operate, and if the number 2 on the left vertical axis is 2, the outdoor unit 140 is not operated and the gas furnace 130 is operated. That is, as described above, the gas furnace 130 and the outdoor unit 140 may operate selectively.

Curved part (B) shown from the bottom to the middle on the vertical axis represents the measured outdoor temperature. The measured outdoor temperature can be determined by the number shown on the right vertical axis. The measured outdoor temperature can vary from -10 degrees to 10 degrees.

As described above, since the set temperature BP is -6.67 degrees and the buffer temperature is set to 2.78 degrees, it can be confirmed that the gas furnace 130 and the outdoor unit 140 are repeatedly switched and operated according to the measured temperature. .

In addition, it can be seen that the operation of the outdoor unit 140 and the gas furnace 130 is switched 11 times for about 150 minutes. This is because the measured outdoor temperature changes repeatedly within the range of -7 degrees to 3 degrees. Therefore, the efficiency of the unitary air conditioner system 100 may be impaired due to frequent switching.

The fact that frequent operation switching over a relatively short period of time is a problem of a temperature sensor measuring the outdoor temperature rather than a change in the actual outdoor temperature. However, as described above, if the buffer temperature is set to be large, frequent operation can be prevented, but inefficiency may be caused as described above.

In the end, it can be seen that it is important to measure the outdoor temperature and ensure the accuracy of the temperature measurement as it is less affected by outside air.

5 is a cross-sectional view of a cover 200 according to an embodiment of the present invention.

Referring to FIG. 5, the outdoor unit 140 may include an outdoor heat exchanger 141 and a housing 145.

The housing 145 may form the exterior of the outdoor unit 140. The outdoor heat exchanger 141 has a wide cross-sectional area so that the refrigerant flowing through the outdoor unit 140 can exchange heat with outdoor air, and at least a part of the outdoor heat exchanger 141 may be installed in the housing 145. In addition, the outdoor heat exchanger 141 may communicate with outside air. Accordingly, even if the housing 145 forms the exterior of the outdoor unit 140, the exterior heat exchanger 141 may not form the exterior.

In addition, the outdoor unit 140 may include a sensing unit 160 for measuring the outdoor temperature and a cover 200 for communicating the sensing unit 160 with external air.

The sensing unit 160 may be installed facing the outdoor heat exchanger 141, and the cover 200 may surround at least a portion of the sensing unit 160 and may be installed spaced apart from the outdoor heat exchanger 141.

The sensing unit 160 may include a temperature sensor 161 that measures temperature and an extension part 163 that transmits information on the measured temperature. Since the temperature sensor 161 measures the temperature around the temperature sensor 161 is installed, it may be desirable to be installed spaced apart from the external heat exchanger 141.

In particular, when the temperature sensor 161 is installed in the housing 145, since the temperature of the housing 145 can be measured as an outdoor temperature by the temperature sensor 161, the temperature sensor 161 is not installed in the housing 145. It may be desirable not to.

In addition, when the temperature sensor 161 is installed in contact with the external heat exchanger 141, heat included in the external heat exchanger 141 may be transferred to the temperature sensor 161. Therefore, it may be preferable that the temperature sensor 161 is installed to be spaced apart from the external heat exchanger 141.

Meanwhile, the external heat exchanger 141 may dissipate heat by the refrigerant flowing through the external heat exchanger 141. For example, when the operation of the outdoor unit 140 is stopped, the outdoor unit 140 may perform a task of recovering a flowing refrigerant, and the recovered refrigerant may be higher than the outdoor temperature.

Accordingly, the cover 200 may include a heat insulating part 210 that blocks heat generated from the external heat exchanger 141. The heat insulation part 210 may be provided to face the external heat exchanger 141. In addition, a heat insulation part 210 may be provided between the temperature sensor 161 and the external heat exchanger 141.

In addition, the cover 200 may include a coupling portion 201 extending outward from the heat insulating portion 210. The coupling part 201 may be combined with the outdoor heat exchanger 141 to separate the cover 200 from the outdoor heat exchanger 141.

Accordingly, the above-described refrigerant may be a heat source 143, and the heat insulating part 210 may block heat generated from the refrigerant heat source 143.

In addition, in order to provide the temperature sensor 161 inside the cover 200, the cover 200 may include a lower surface 220.

The lower surface 220 may include a through hole h formed therethrough, and a shield member 221 may be installed in the through hole h. Accordingly, the extension part 163 may be coupled to the through hole h with the shield member 221 interposed therebetween. That is, the extension part 163 may penetrate the lower surface 220 and the temperature sensor 161 may be provided inside the cover 200.

However, as will be described later, the cover 200 may include not only a lower surface 220, but also a front surface 210 and a rear surface 230, an upper surface 240 and a side surface 250. Therefore, the extension part 163 for providing the temperature sensor 161 inside the cover 200 may be provided through one of the front surface 210 and the rear surface 230 and the upper surface 240 and the side surface 250. I can.

Accordingly, the temperature sensor 161 may be less affected by the refrigerant heat source 143 as described later, and may be exposed to external air by the communication unit 251.

6 is a perspective view showing a state of the cover 200 coupled to the outdoor heat exchanger 141.

The cover 200 may have a rectangular parallelepiped shape. Accordingly, the cover 200 may include a front surface 210 and a lower surface 220, a rear surface 230, an upper surface 240, and a side surface 250.

The front surface 210 may be one surface of a rectangular parallelepiped provided to face the outdoor heat exchanger 141. In addition, the heat insulating part 210 may be the front surface 210.

The upper surface 240 may be one surface of a rectangular parallelepiped that is bent and extended from the upper side of the front surface 210. In addition, the lower surface 220 may be one surface of a rectangular parallelepiped that is bent and extended from the lower side of the front surface 210.

The side surface 250 may be one surface of a rectangular parallelepiped connecting the upper surface 240 and the lower surface 220 in the height direction. In addition, the rear surface 250 may be one surface of a rectangular parallelepiped connecting the upper surface 240 and the lower surface 220, and may be one surface of a rectangular parallelepiped connecting the two side surfaces 250.

The side surface 250 may include a communication part 251. The communication part 251 may be formed through the side surface 250, and thus the inside of the cover 200 may communicate with the outside air through the communication part 251. The communication part 251 may be formed on the two side surfaces 250, respectively. Further, the communication part 251 may have a rectangular shape, but is not limited thereto, and a shape of a hole capable of communicating the inside of the cover 200 with the outside will be considered sufficient.

The above-described communication part 251 is provided on the side surface 250, but the communication part 251 may be formed on the other side. For example, it may be formed on at least one of the lower surface 220, the rear surface 230, or the upper surface 240. However, in the case of the front surface 210, it may be preferable that the communication part 251 is not provided on the front surface 210 because it serves as heat insulation.

Therefore, the through hole (h) is provided on one surface other than the front surface 210 so that the extension part 163 can connect the inside and the outside of the cover 200, and the communication part 251 on one surface except the front surface 210 ) May be provided.

In addition, the cover 200 is not limited to a rectangular parallelepiped shape, and a shape capable of communicating a partial area with the outside while surrounding the temperature sensor 161 will be sufficient. However, even in this case, one area of the cover 200 that most closely faces the outdoor heat exchanger 141 may block the temperature sensor 161 and the outdoor heat exchanger 141.

In particular, since the airflow caused by the operation of the fan 149 may affect the temperature sensor 161, the communication part 251 is installed in the area of the cover 200 which is relatively less affected by the airflow of the fan 149. Can be.

In addition, an insulating material may be provided on at least a portion of the inner surface of the cover 200. In particular, an insulating material may be provided on at least a part of an inner surface or an outer surface of the heat insulating part 210. Accordingly, it is possible to prevent the radiant heat generated from the refrigerant heat source 143 from affecting the temperature sensor 161.

Accordingly, the temperature sensor 161 may be installed to be spaced apart from the outdoor heat exchanger 141 by a predetermined distance. In addition, the heat insulation part 210 may be provided between the outdoor heat exchanger 141 and the temperature sensor 161 to minimize the influence of the refrigerant heat source 143 on the temperature sensor 161. In addition, the cover 200 excluding the communication part 251 is installed to surround the temperature sensor 161, so that the influence of the airflow by the fan 149 on the temperature sensor 161 can be minimized.

Accordingly, even if the outdoor temperature is around the set temperature BP, the sensing unit 160 may more accurately measure the outdoor temperature. Accordingly, frequent switching of the operation of the gas furnace 130 and the outdoor unit 140 may be reduced.

The present invention is not limited to the above-described embodiments, and as can be seen from the appended claims, modifications can be made by those of ordinary skill in the field to which the present invention belongs, and such modifications fall within the scope of the present invention. You will see it.
