Description

[Detailed explanation of the idea] The present invention relates to an improvement in a cooling/heating device.

Conventional cooling and heating systems were either compression or absorption types that circulated the medium to evaporate and condense it, but both required large equipment and complex configurations relative to their cooling and heating capacities. There were drawbacks such as the need for maintenance.

The purpose of this invention is to enable cooling and heating with a new mechanism that is completely different from conventional methods.
In addition to making equipment small, lightweight, and simple,
The purpose is to increase the specific output.

The characteristic configuration of the cooling/heating device according to the present invention is that a compressor that supplies compressed air is connected to a gas turbine, a combustor is interposed in the air supply path from the compressor 1 to the gas turbine, and the compressor is combusted. a first heat exchanger provided with a flow path for supplying fuel gas to the compressor and cooling the air from the compressor; a first impeller device connected to the first heat exchanger;
a second impeller device interlocked with the first impeller device, an outside air blower, a second heat exchanger that cools or heats the air from the first impeller device with air from the blower, and the second impeller device; A recovery flow path is provided for temperature control air from the impeller device, and the air cooled by the first heat exchanger is transferred to the suction port of the first impeller device, the second heat exchanger, and the second impeller device. in the order of the inlet port, the recovery channel, and the outside air from the blower,
The cooling state is supplied to the first heat exchanger and the second heat exchanger in this order, and the air cooled by the first heat exchanger is supplied to the inlet of the first blade wheel device and the second heat exchanger.
a heat exchanger, the first heat exchanger, the suction port of the second impeller device, and the recovery flow path, and in a heating state in which outside air from the blower is supplied to the second heat exchanger, respectively. A valve device for switching is provided, and its effects are as follows.

That is, when the above-mentioned cooling state is achieved by the valve device, the first impeller device acts as a compressor and the second impeller device acts as a turbine. As a result, the air at room temperature and atmospheric pressure, as shown by the dots in Figure 3, is pressurized and heated by the compressor, resulting in the air reaching the state shown by the dots in Figure 3, and due to high-load combustion in the combustor, The gas heated at equal pressure from the point state to the point state is supplied to the gas turbine, the gas turbine and compressor are rotated together, and the gas changes from the point state to the point state as shown in Figure 3 by the gas turbine. . The air from the compressor is then passed through the first heat exchanger to the third heat exchanger.
After being isobarically cooled from the state of the point in the figure to the state of the point, it is supplied to the first impeller device, where the pressure and temperature are increased, and the air changes from the state of the point in Fig. 3. becomes a point. Furthermore, after the air from the first impeller device is isobarically cooled by the second heat exchanger from the state of the point in FIG. 3 to the state of the point,
The air is supplied to the second impeller device, the first and second impeller devices are rotated together, and the second impeller device recovers the air whose pressure and temperature have decreased to the point shown in Figure 3 for cooling purposes. .

Further, when the above-mentioned heating state is achieved by the valve device, the first impeller device acts as a turbine and the second impeller device operates as a turbine.
The wheel system acts as a compressor. As a result, the air at room temperature and atmospheric pressure, shown by the dots in Figure 4, is pressurized and heated by the compressor, and the air reaches the state shown by the dots in Figure 4, resulting in high-load combustion in the combustor. The gas heated at equal pressure from the point state to the point state is supplied to the gas turbine, the gas turbine and compressor are rotated together, and the gas changes from the point state to the point state as shown in Figure 4 by the gas turbine. . After the air from the compressor is cooled by the first heat exchanger from the point state in FIG. 4 to the point state, it is supplied to the first impeller device, and the first impeller device changes the pressure The temperature is reduced so that the air goes from the dot state of FIG. 4 to the dot state. Furthermore, the air from the first impeller device is heated isobarically from the point state in FIG. 4 to the point state by heat exchange with the external heat source fluid from the blower in the second heat exchanger, and After being uniformly heated by the heat exchanger from the point state shown in FIG. 4 to the point state, the heat is supplied to the second impeller device which rotates integrally with the first impeller device, and the second impeller device rotates integrally with the first impeller device. The air whose pressure and temperature have increased from the point state to the point state is recovered for heating purposes.

Therefore, it is only necessary to provide components that are relatively small, lightweight, and simple in construction, that is, a compressor, a gas turbine, first and second impeller devices, a combustor, a blower, a heat exchanger, and a valve device. In addition, since heating and cooling can be switched between these components in a rational manner, the equipment as a whole can be made much smaller and lighter than conventional compression and absorption types. It can be made advantageous in terms of equipment and handling, there is no trouble due to medium leakage, it can be made advantageous in terms of maintenance, and furthermore, it can be made to have a large specific output.
