Abstract

PURPOSE:To control the output of low temperature water over a wide range and improve operation efficiency by allowing a motor to operate and a rotary shaft to increase its rotary speed when a rotary speed required from a load side exceeds a rotary speed of self operation, and forcing a brake to operate and the rotary shaft to reduce its rotary speed inversely when a required rotary speed fails to exceed the rotary speed of self operation. CONSTITUTION:When a rated output of cooled water is excessive to, say, a cooling load, the cooled water outlet temperature of an endothermic heat exchanger 12 drops below a predetermined temperature. A comparison means 33 compares a required rotary speed calculated based on the differential temperature with a rotary speed nn of self operation and issues a command that the required rotary speed should be below the rotary speed of self operation, thereby actuating a brake means 35. As a result, a signal transmitted from a controller 32 forces a brake 29 to act so that the rotary speed of a rotary shaft 24 may be reduced to the required rotary speed. On the contrary, when the output of cooled water is insufficient to the cooling load, the comparison means 33 issues a command that the required rotary speed should exceed the rotary speed of self operation, thereby actuating a back up means 34. As a result, a signal transmitted from the controller 32 forces a motor 28 to operate so that the rotary speed of the rotary shaft 24 may be increased up to the required rotary speed.

(*) Effect In the heat pump device of the present invention, when the required rotation speed requested from the cooling/heating load side exceeds the rotation speed of self-operation, the electric motor is operated according to a command from the controller to reduce the rotation speed of the rotating shaft. Conversely, when the required rotational speed falls below the rotational speed for self-operation, the brake is operated by a command from the controller and the rotational speed of the rotating shaft decreases, thereby increasing or decreasing the operating speed of the display service ton. Therefore, the number of expansions per unit time of the low temperature gas in the low temperature side cylinder and the number of reciprocations per unit time of the medium temperature gas in the heat exchanger for heat radiation are increased or decreased over a wide range. Due to this effect, the amount of heat pumped up from the cold water by the low-temperature gas and the amount of heat radiated from the medium-temperature gas to the hot water, in other words, the output of cold and hot water can be adjusted over a wide range.

Now, if the rated chilled water output obtained by self-operation of the external combustion engine (1) is excessive for the cooling load, the chilled water outlet temperature of the endothermic heat exchanger (12) will drop below the set temperature. descend. This decrease is detected by the cooling detector (30
) is determined based on the temperature difference between the chilled water temperature detected by the set temperature and the set temperature, and a comparison means (33) compares the required rotation speed calculated based on this temperature difference and the rotation speed ne for self-powered operation;
The required rotation speed is the rotation speed n for self-driving operation. The brake means (35) is activated by issuing a command to lower the rotational speed of the rotary shaft (24) to the required rotational speed. As a result, the number of times the low temperature gas expands per unit time in the low temperature side cylinder (4) is reduced, and the amount of heat pumped up is reduced, making it possible to extract a cold water output commensurate with the cooling load. Conversely, when the chilled water output 4 is insufficient for the cooling load, a command is issued from the comparison means (33) that the required rotation speed exceeds the rotation speed nc for self-powered operation, and the backup means (33)
4) is activated, and the electric motor (28) is activated by the signal from the controller (32).
) to increase the rotational speed of the rotating shaft (24) to the required rotational speed. This increases the number of times the low temperature gas expands per unit time in the cylinder (4) and increases the amount of heat pumped up, making it possible to extract cold water output according to the load during cooling operation. This is the same when hot water output is taken out for heating, and the heating detector (31
), the required rotation speed calculated based on the temperature difference between the hot water temperature and the set temperature and the rotation speed nc for self-powered operation are compared by the comparison means (33), and the required rotation speed is determined to be the rotation speed n for self-powered operation. , the brake means (35) activates the brake (
29) operates to lower the rotational speed of the rotating shaft (24) to the required rotational speed, and conversely, when the required rotational speed exceeds the self-operation rotational speed n, the backup means (34) lowers the rotational speed of the rotating shaft (24) to the required rotational speed.
) operates to increase the rotational speed of the rotating shaft (24) to the required rotational speed.

In this way, the brake (29) and the electric motor (28) can increase or decrease the rotation speed of the rotating shaft (24) over a wide range from nl, 8 to nearly zero, as shown in Figure 2. ,
Moreover, it is possible to adjust the output of cold and hot water by setting just the right amount of power b watts generated by the self-operation of the external combustion engine (1). Moreover, since there is no need to excessively adjust the combustion amount of the burner (36) for the purpose of increasing or decreasing the rotation speed of the rotating shaft (24), overheating of the external combustion engine (1) is hardly caused. Moreover, there is almost no interruption of operation due to insufficient power generated due to insufficient heating of the external combustion engine (1). In other words, it is possible to adjust the chilled/hot water output over a wide range without incurring interruptions in operation that would cause a reduction in operating efficiency. In addition, as a suitable design condition for setting the generated power b watts when the external combustion engine (1) runs under its own power to just the right amount, the rotation speed n when the external combustion engine (1) runs under its own power is the maximum required rotation speed. 50% of the value n, 8 to 9
It is desirable to set it to 0%; if it is less than 50%, a large-capacity electric motor (28) will be required, and if it is more than 90%, the braking force will become large, causing a decrease in efficiency. These design conditions include the frictional resistance of the driving part of the external combustion engine (1), the flow resistance of the working gas, the thermal resistance of the external combustion engine (1), the cross-sectional area of the piston rods (21) and (22), and the flow resistance of the working gas. Can be selected based on design values such as pressure and temperature.

In addition, the power generated by the external combustion engine (1) is generated by the cylinder (2).

Since it increases or decreases depending on the size, the power generated by the external combustion engine (1) can be changed by changing the size of this cross-sectional area. In other words, the slope of the dashed line in FIG. 2 can be changed.
