Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a steam cooling and hot water supply system.

Conventional cooling systems have been either compression type or absorption type, which circulates refrigerant while evaporating and condensing it, but both require large equipment for their cooling capacity, complex configurations, and require maintenance. This method had drawbacks such as requiring a lot of work.

An object of the first invention is to make the equipment compact, lightweight, and simple by allowing cooling to be performed using a novel mechanism that is completely different from conventional systems.

The characteristic configuration of the air conditioner according to the first invention is that a first compressor that supplies air under pressure is connected in conjunction with a first gas turbine, and a combustor is provided in an air supply path from the first compressor to the 111 gas turbine. An eighth compressor is interlocked with the eighth gas turbine, and has a flow path for supplying fuel gas to the combustor, and pressurizes the air from the first compressor. A cooler for cooling the pressurized air is provided in the air supply path to the second compressor and the air supply path from the second compressor to the second gas turbine, and a flow path for recovering low-temperature air for cooling from the eighth gas turbine is provided. The effects of providing the channel are as follows.

The air at room temperature and atmospheric pressure, indicated by the dot in Figure 2, is the first.
The compressor pressurizes and raises the temperature of the air, bringing it to the state shown by point ■ in Figure 8. Due to high-load combustion in the combustor, the air is isobarically heated from point ■ to point ■ in Figure 2. The gas is supplied to the first gas turbine, the first gas turbine and the first compressor are rotated together, and the first gas turbine changes the gas t'i from the state of point (2) in FIG. 2 to the state of point (2) VC. Then, the air from the first compressor is uniformly cooled by the cooler from the state of point ■ to the state of point ■ in FIG. 2, and then is supplied to the second compressor,
The pressure and temperature are increased by the second compressor, and the air changes from the state of point ■ in Figure 2 to the state of point ■. Furthermore, the air from the second compressor is transferred to the second
After being isobarically cooled from the state of point ■ in the figure to the state of point ■, it is supplied to the second gas turbine, where the second gas turbine and second compressor are rotated together, and the second gas turbine is supplied to the second gas turbine. The air whose pressure and temperature have decreased to the state of point (■) is recovered for cooling purposes.

Therefore, both of them are relatively small, lightweight, and easy to configure.
It is only necessary to install individual compressors, gas turbines, coolers, and one combustor, and overall the equipment is much smaller and lighter compared to conventional compression and absorption types. In addition to being advantageous in terms of handling and repair, it is also advantageous in terms of repair.

An object of the eighth invention is to add a simple improvement to the air conditioner according to the first invention by effectively utilizing its structure, so that hot water can also be supplied.

In addition to the characteristics of the cooling device according to the first invention, the characteristic structure of the apparatus according to the eighth invention is such that hot water is heated by the hot gas in the air supply path from the combustor to the first gas turbine. The reason is that a heat exchanger is provided, and its effects are as follows.

In other words, the gas supplied from the combustor to the first gas turbine has an extremely high temperature as shown by point ■ in Figure 8, so the amount of wet coal at the gas turbine inlet is restricted due to the material of the gas turbine blades. If the gas needs to be cooled, the heat obtained from this cooling can be effectively used to modify the gas by simply adding a small and simple heat exchanger, in other words, without compromising the advantages of the first invention. With no modification required, hot water can now be supplied, providing an even more convenient facility.
