Definitions
- the high-temperature exhaust gas exhausted by fuel combustion is sent to an exhaust gas boiler, and after being exchanged with water, is exhausted outside the system as exhaust gas.
- high-pressure steam is extracted from the exhaust gas boiler, and hot water is extracted from the cooling water.
- the power of the air compressor 1 can also be obtained from the above-described exhaust / bin power of the heat engine 50 for cogeneration.
- Fig. 10 shows a piping diagram of the ice making heat exchanger 4 buried in the competition course
- Fig. 11 shows its plan view.
- a cold air outgoing pipe 55a and a cold air returning pipe 56b, and a cold air outgoing pipe 55b and a cold air returning pipe 56a are attached to both sides of the course, respectively.
- the base ends 57a, 57b of the cool air outgoing pipes 55a, 55b are connected to the air inflation device, and the ends 58a, 58b are sealed.
- the cold air return pipes 56a and 56b are U-shaped pipes, and one end 59a and 59b are connected to a heat recovery heat exchanger.
- the other ends 60a and 60b are sealed.
- FIG. 13 is a cross-sectional view showing a curved course of a Bobsleigh course equipped with an ice making device according to the present invention.
- the basic configuration is the same as the configuration of the straight course described in Fig. 12; 75 is a concrete base, 76 is a concrete foundation, and 77 is a concrete base. Indicates a thermal insulation layer.
- the heat insulating mo- tor layer 77 is formed in an L-shape in cross section in order to form a bank.
- the temperature of the low-temperature air supplied to the ice-making heat exchanger 4 is 14 ° C, and the temperature of the air exiting from the ice-making heat exchanger 4 is -15 ° C. Set to C.
- the surface temperature of the ice formed should be maintained at 11 to 13 ° C.
- the operating conditions of the ice making equipment are as shown in Fig. 1 and are as follows.
- the air is sent to an ice making heat exchanger 4 where ice is made under the above conditions in an on-ice facility.
- the air from the ice making heat exchanger 4-15 passes through the heat recovery heat exchanger 5, is heated to 15 ° C, and returns to the air compressor 1.
- the power of the air compressor 1 is obtained from the power shaft 51 of the heat engine 50 for the co-operated drain.
- the ice making equipment can be used.
- the cooling capacity obtained is 0.28
- the recovered heat is 0.63
- the total amount of heat obtained from the cogeneration system and the ice making system is as follows:
- This value is the total efficiency of a conventional engine-driven heat pump that uses a heating medium such as a fan.
- the calorific value is the coefficient of performance of the conventional power-type refrigerator using a heating medium such as chlorofluorocarbon, converted to primary energy.
- the shaft output of the heat engine 50 is used as the power. It is possible to supply all of the generators for the energy generation. In some cases, the shaft output of the heat engine 50 can be used as a transport power source for the passengers and cargo of the facility. In this case, the exhaust of the heat engine is 2 atm at 580 ° C, and the exhaust pressure at the outlet of the evening bin is 1 atm at 43 ° C, and the exhaust power at the boiler is 250 ° C. If the energy of the supplied fuel is 1, for example, the shaft output power is 0.25, the output power of the exhaust turbine is 0.1, and the recovered heat of steam and hot water is 0. It will be about 32.
- hot water and hot air are taken out of the heat exchanger 2A and the heat exchanger 2B described in FIG. 1, but this is at the foot of the audience seats.
- the hot water pipe 70 in Fig. 12 and the hot water pipe 80 in Fig. 13 are piped so that heat can be supplied to the feet of spectators and related parties standing near the course. .
- the above embodiment is an example in which the present invention is applied to an outdoor bobsley recreational competition course.
- the present invention is similarly applied to indoor stadiums such as skates.
- the ice making heat exchanger 4 is configured in various forms according to the ice making area and the thickness and shape of the ice making. For example, a cold air tube was buried inside the heat transfer mortar, a cold air tube was formed in a finned coil, or a panel heat exchanger was constructed. Thus, the strength compensation and heat transfer of the cold air tubes are improved.
- the tubes of the heat exchanger 4 for making ice were passed through the cold air outgoing tube 55a and the cold air returning tube 56a to pass low-temperature air.
- the pipes are divided into two groups, the pipes 61a and the pipes 61b that allow low-temperature air to pass between the cold-air outgoing pipes 55b and the cold-air returning pipes 56b. By arranging them alternately, the entire facility for sports on ice, such as skating links, can be cooled evenly and uniformly. Swell.
- the present invention even when air is used as a heat medium by heat recovery and power recovery, a refrigeration cycle with a high coefficient of performance can be formed. And since the cold for ice making is obtained through the air, the ice making at the ice utilization facility is completely pollution-free. Conversely, by releasing cold air, which is a heat medium, to the outside air, it can be used for ice making. In this case, the intended form of the ice surface is easily formed. In addition, the heat of compression of the compressor used to obtain cold air is collected in the form of hot air or hot water. Since this can be used to create a thermal environment, power energy can be used effectively. Also, since it is a plumbing facility with only air and water, construction is simple and repair is easy. Also, by combining with a heat engine for cogeneration, it is possible to achieve 'total energy saving' and 'running core' which is a drawback of pneumatic ice making equipment. The burden on the storage is greatly reduced
