に構成されている。 Conventionally, there is a device of this type having the configuration shown in FIG. FIG. 1 shows a conventional example for supplying hot water and space heating using engine exhaust heat of an apparatus for heating and cooling by rotating a compressor (not shown) by an engine 1. In the figure, exhaust heat from an engine 1 heats hot water 3 in a hot water storage tank 2 and is supplied for hot water supply, and is also absorbed by a heating heat exchanger 4 provided in the hot water storage tank 2 and dissipates heat for heating. This is a system in which the heating device 5 is used for heating. Further, when the engine cylinder cooling water temperature rises, the heat radiator 6 is configured to radiate heat.

ーバーヒートを生じる。 However, in the configuration of such a device, since the heat recovery circuit from the engine 1 to the hot water storage tank 2 and the heating circuit from the hot water storage tank 2 to the heating radiator 5 are completely independent, The number of circulation pumps 7, 8 and heat exchangers 4, 9 in the hot water storage tank that make up the circuit increases, making the device expensive.
Furthermore, when heating with the heating radiator 5, the heating effect cannot be obtained unless the heat medium in the heating circuit reaches a predetermined temperature or higher, but in order to do so, it is necessary to increase the temperature of the hot water in the hot water storage tank 2, and the heating time If you want to make the water longer, you will need to increase the capacity of the hot water storage tank in order to increase its heat capacity. In addition, since engine 1 is used as a heat source, it is necessary to cool engine 1, and the cooling water is also used as recovered heat, but as the hot water temperature in the hot water storage tank rises, the cylinder cooling temperature also rises, preventing overheating. arise.

の回収効率も悪くなるという欠点を有している。 Therefore, in order to operate at a cylinder cooling temperature below a predetermined temperature, a radiator 6 is provided in parallel so that when the cylinder head temperature is above a predetermined temperature, the radiator 5 radiates heat. However, when they are arranged in parallel like this, when the cylinder head temperature reaches a predetermined temperature, the exhaust heat is not circulated into the hot water storage tank 2, so the amount of heat recovered in the hot water storage tank becomes zero, and the boiling temperature in the hot water storage tank is reduced. This has the disadvantage that the time is slow and the recovery efficiency of waste heat is poor.

きくなる。 The operation of the apparatus of the present invention having such a configuration will be explained. First, in the summer and intermediate seasons when heating is not required, the heat medium circulates as shown by solid lines and broken lines in the figure, and heat from the engine body 10 heats the hot water 15 in the hot water storage tank 13. In other words, the solid line indicates a case where the cylinder cooling water or the temperature at the temperature sensor 27 provided in the cylinder head is below the allowable temperature for engine overheating. The heat medium from the engine body radiates heat in the hot water storage tank heat exchanger 14, goes straight through the three-way solenoid valves 21 and 22, passes through the circulation pump 23, and passes through the three-way solenoid valve 25.
This constitutes a circuit that goes straight through and returns to the engine body 10. Further, when the temperature at the temperature sensor 27 becomes equal to or higher than the set temperature, the solenoid valve 22 in the radiator 20 is operated to flow the heat medium to the radiator 20, and the radiator 20 is operated (as indicated by the broken line). ). At this time, conventionally, the radiator 20
Because they were installed in parallel, the hot water storage tank
The heat medium is not circulated, so the heating in the hot water storage tank is zero, but in the present invention, the heat is radiated after first passing through the hot water storage tank heat exchanger 14.
The heating efficiency of the hot water storage tank 13 during the entire operating time is increased.

などには特に効果を有する。 Next, during heating, the heating medium circulates as shown by the dashed-dotted line and the dashed-double-dotted line in the figure to perform heating. That is, the first case is when the engine 10 is not operating and the hot water 15 in the hot water storage tank 13 is boiling. At this time, the three-way solenoid valve 25 leading to the short circuit 26 operates, and the heat medium is The internal heat exchanger 14 absorbs heat, the three-way solenoid valve 21 operates so that the heat passes through the heating radiator 19, the heating radiator 19 radiates heat, and the heat enters the circulation pump 23. The second condition is when the engine 10 is running and heating the hot water 15 in the hot water storage tank 13, but even at this time, the temperature of the heat medium in the heat exchanger 14 in the hot water storage tank is It has a temperature difference with hot water 15. Therefore, by setting the set temperature of the temperature sensor 28 to the lowest temperature at which the heating effect of the heating radiator 19 is obtained, heating can be performed even if the hot water 15 is not boiled.
At this time, the heat medium exits the engine 10 as shown by the two-dot chain line, passes through the hot water storage tank heat exchanger 14, passes through the heating radiator 19, and returns to the circulation pump 23. Further, this heating circuit is particularly effective when the engine is operated at full load, for example, and exhaust heat recovery is performed in excess of the heat dissipation capacity of the hot water storage tank heat exchanger 14.

より浴槽での加熱時間を早めることができる。 Next, another embodiment of the present invention shown in FIG. 3 will be described. This is because, in the embodiment shown in FIG. 2, a circuit is provided in parallel via a solenoid valve 31 in which the heat medium passes through a heat exchanger 30 in the bathtub 29 before entering the hot water storage tank 13 of the heat recovery circuit. It is something that In this circuit, when a load occurs in the bathtub, the hot water from the hot water storage tank is used, but when additional heating is required, the exhaust heat from the engine can be used to reheat the bath. . Note that the parts common to those in FIG. 2 are not numbered and their explanation is omitted. With such a configuration, even if the hot water 15' in the hot water storage tank 13' has not reached a temperature that allows for cooling, the operation of the engine 10', that is, the heating and cooling load (excluding heating with hot water) ), reheating is possible and has the effect that it is not necessary to install another heat source for reheating or to reduce the capacity of the hot water storage tank 13'. Furthermore, by providing these circuits in parallel, the heating time in the bathtub can be shortened.

る。 As described above, in the present invention, since the heating radiator and the surplus heat radiator are provided in series in the heat recovery circuit, the circulation pump and the hot water storage tank heat exchanger are It becomes possible to integrate the two into one, which simplifies the configuration of the device. Furthermore, since the heating radiator and the radiator are provided downstream of the heat exchanger in the hot water storage tank, the efficiency of recovery into the hot water storage tank is improved. Furthermore, by adding a bypass that can directly connect the engine inlet and engine outlet of the heat recovery circuit, it is possible to prevent heat radiation from the engine part during heating using the heat in the hot water storage tank, and to achieve efficient heating. In addition, the operation control of heating radiators,
By adding a device that uses the temperature at the outlet of the hot water storage tank, the range of heating using engine exhaust heat can be expanded.
