The present invention relates to a subway waste heat recovery device that recovers and effectively uses waste heat within a subway station building. In general, in subways, in order to maintain the environment within the station building, fans are installed in, for example, the supply cylinder and exhaust stack of the station building, and forced air supply and exhaust are performed using these fans. Recently, efforts have been made to set a target temperature within the station building, and to maintain this temperature at the target temperature, the number of rotations of the fan is controlled to adjust the air volume, thereby saving energy for the fan power. That is, a temperature control device is installed in the station building or the exhaust stack, and an electric motor with inverter control is connected to the fan. The temperature control device detects the temperature inside the station building or the exhaust stack, and the inverter-controlled electric motor is controlled accordingly. Note that the exhaust temperature is approximately the same as the temperature inside the station building.
In the case of exhaust stack temperature, the temperature inside the station building tends to vary due to differences in the heat generation density of each zone, but since it is collected by ducts etc., there is an advantage that the average temperature can be detected. In general, subways are said to be cool in the summer because the heat generated by train power, the human body, and lighting equipment are absorbed by the walls, underground, and underground water, but recently, due to the increase in transportation volume, the heat generated in the subways has increased. As a result, the temperature inside subway station buildings tends to rise year by year, and the energy effect of the aforementioned air volume control may decrease, increasing the need for forced cooling in the future. As shown in Figures 1 and 2, the temperature inside the station building is considerably higher than the outside temperature. 1st
The figure shows changes in the average temperature inside a subway station building (indicated by a solid line in the figure) and outside air temperature (indicated by a broken line in the figure), with the year on the horizontal axis and temperature on the vertical axis. In addition, Figure 2 shows the month on the horizontal axis and the temperature on the vertical axis, showing changes in the average temperature inside the subway station building (shown by the solid line in the figure) and the temperature inside the tunnel (shown by the dashed line in the figure). This is a diagram. As is clear from this,
The temperature inside the station building is higher than the outside temperature, and as mentioned above, it tends to rise year by year, and for this reason some station buildings are equipped with air conditioning equipment. Therefore, it has become necessary to recover and effectively utilize the waste heat that was previously wasted into the atmosphere. The present invention was developed based on the above points, and its purpose is to maintain a healthy environment inside subway station buildings and save energy by recovering and effectively using the waste heat that was conventionally exhausted. The object of the present invention is to provide an exhaust heat recovery device for a subway that can achieve the following. In other words, the subway waste heat recovery device according to the present invention includes an air heat exchanger of an air heat source heat pump installed in an exhaust stack communicating with a subway station building, an air heat exchanger fan installed in the exhaust stack, and a An inverter-controlled electric motor connected to a heat exchanger fan, a recirculation path branching from the exhaust stack downstream of the air heat exchanger and fan and communicating with the station building, and a recirculation path connected to the station building at the branch point of the recirculation path. A recirculation damper and an exhaust damper installed in the road and the exhaust stack, respectively, and a temperature installed in the station building or the exhaust stack to detect the temperature inside the station building or the exhaust stack and control the inverter-controlled electric motor based on the detected value. A control device, a refrigerant circuit that exchanges heat with the air in the exhaust stack via the air heat exchanger, a condenser inserted in the refrigerant circuit, and a refrigerant that flows through the refrigerant circuit via the condenser. It is characterized by comprising a hot water piping system for heat exchange. In other words, an air heat exchanger for an air heat source heat pump is installed in the exhaust stack, and for example, in the summer, the air inside the exhaust stack exchanges heat with the refrigerant circulating in the refrigerant circuit, and the cooled air is transferred to the recirculation damper by closing the air damper. The air is then opened and returned to the station building via a recirculation path to be used for cooling the station building. On the other hand, the heated refrigerant is used as a heat source for producing hot water via a condenser. Then, during the winter and intermediate seasons, the air whose heat has been removed by heat exchange with the refrigerant is released into the atmosphere, and the heated refrigerant is used as a heat source for hot water production as in the summer. Here, by controlling the rotation speed of the heat exchanger fan using a temperature control device via an inverter-controlled electric motor, it is possible to increase or decrease the amount of latent heat and sensible heat removed in the air heat exchanger, thereby increasing or decreasing the cooling effect. This makes it possible to maintain the temperature inside the station building at the target temperature and reduce power consumption. Therefore, the temperature inside the station building can be maintained at the target temperature for each month or each season, and at the same time, the power of the heat exchanger fan can be reduced, making it possible to maintain a comfortable environment. In addition, it becomes possible to recover waste heat and use it effectively, such as by using it as a heat source for hot water production. An embodiment of the present invention will be described below with reference to FIG. FIG. 3 is a diagram showing a schematic configuration of a subway exhaust heat recovery device according to the present invention. Reference numeral 1 in the figure indicates a part of the subway station building. An exhaust stack 2 is communicated with the station building 1, and an exhaust stack 3 is branched off from the exhaust stack 2. An air heat exchanger 5 and a heat exchanger fan 6 of an air source heat pump 4 are installed in the exhaust pipe 3 . An inverter-controlled electric motor 7 serving as a drive mechanism is connected to the heat exchanger fan 6. A refrigerant circuit 9 of an air source heat pump is connected to the heat transfer tube 8 of the air heat exchanger 5. This refrigerant circuit 9 includes a refrigerant communication pipe 1
0, the refrigerant compressor 11, a condenser 12, and a refrigerant expansion valve 13 are inserted into the refrigerant communication pipe 10. The hot water pipe 14 is connected to the condenser 12.
The refrigerant compressor 11 is connected to a compressor driving motor 11A. The exhaust pipe 3
A recirculation path 15 is branched into the station, and the other end of the recirculation path 15 is connected to the station building 1. An exhaust damper 16 and a recirculation damper 17 are inserted into the exhaust pipe 3 and the recirculation path 15, respectively. Furthermore, an air supply cylinder 18 is connected to the station building 1, and an air supply fan 19 is connected to this air supply cylinder 18.
is installed. An inverter-controlled electric motor 20 is connected to the air supply fan 19 . A temperature control device 2 is installed inside the station building 1 or inside the exhaust stack 2.
1 is provided. This temperature control device 21 detects the temperature inside the station building 1 or the exhaust stack 2, controls the inverter-controlled electric motor 7 of the heat exchanger fan 6, adjusts the rotation speed of the heat exchanger fan 6, and controls the air volume. The temperature inside the station building 1 is maintained at the target temperature. According to the above configuration, first, the inside of the station building 1 is ventilated by the heat exchanger fan 6 during the summer. At this time, the rotation speed of the heat exchanger fan 6 is controlled by the temperature control device 21 via the inverter-controlled electric motor 7. When the air ventilated by the heat exchanger fan 6 passes through the air heat exchanger 5, it exchanges heat with the refrigerant flowing through the heat exchanger tubes 8 and is cooled. When the station building 1 requires cooling, the exhaust damper 16 is closed and the circulation damper 17 is opened to supply cooled air to the station building 1 via the recirculation path 15 for cooling. On the other hand, the refrigerant that has been heated and vaporized is sent to the refrigerant compressor 11.
The refrigerant flows into the condenser 12 via the refrigerant expansion valve 13, exchanges heat with the hot water flowing through the hot water pipe 14, is cooled and condensed, and returns to the heat exchanger tube 8 again via the refrigerant expansion valve 13. The heated hot water is then used for hot water supply, etc. At this time, for example, the station building exhaust heat amount is 100kcal/ m2・h, the air temperature at the inlet of air heat exchanger 8 is 30℃, the outlet temperature is 25℃,
If the hot water supply temperature is 60℃, approximately 126kcal/ m2・h
heat can be recovered. For example, if a turbo chiller is used to cool station building 1,
For a cooling load of 100kcal/ m2・h, approximately 125kcal/ m2・h of heat must be discharged into the atmosphere at a temperature level of 30℃, but according to this example, heat of about 50℃~90℃ must be discharged to the atmosphere. It is extremely efficient as it can cool the station building 1 while recovering heat of about 0.9°C.
Further, since the air volume is controlled by the temperature control device 21, the temperature inside the station building 1 can be maintained at the target temperature, and energy saving can also be achieved. That is, by controlling the fan rotation speed and controlling the fan air volume using the temperature control device 21, it is possible to control the sensible heat removal amount and the latent heat removal amount for the same refrigerating capacity of the air heat exchanger. When the air volume is increased, the air heat exchanger outlet temperature increases, the latent heat load decreases, and the amount of sensible heat removed increases, increasing the cooling effect. Conversely, when the air volume is decreased, the air heat exchanger outlet temperature decreases and the latent heat load decreases. increases, the amount of sensible heat removed decreases, and the cooling effect decreases. This allows the station building temperature to be maintained at the target temperature.
