However, since the structure is complicated, the structural stability is poor and the turbine and the generator are integrally combined with each other by avoiding the electric power generator for the heating pump cooling / By providing a turbine generator, it is easy to manufacture and lightweight because it is simple in structure, and it is economical, safe, and also it has high rotational efficiency and high efficiency output. Therefore, it is possible to achieve high efficiency and continuous power generation And development To a turbine generator for a heat pump heating and cooling system of a gas turbine type.

Korea is one of the countries lacking energy resources, and energy saving is an essential task. When coal and oil are burned, it emits a lot of CO 2, which is the cause of air pollution and global warming.

Among the alternative energy sources, the heat pump absorbs heat from a low-temperature heat source to heat the high-temperature heat source. The heat pump is widely used for heating and cooling the room. The heat pump heating and cooling system And the system is selectively operated according to the cooling mode or the heating mode so that the refrigerant flows in the opposite direction to each other and cooling, heating, and hot water supply are performed according to the selection mode, And the heating performance is also high.

1, a heat pump is generally composed of a compressor 1, a condenser 2, an expansion valve 3, and an evaporator 4 so that the circulating medium repeats liquefaction and vaporization, The heat pump has a high initial installation cost, but the cooling / heating ratio during operation is very low, so that the demand for the heat pump is increasing as it has a cost saving effect in the long term.

The heat pump is composed of a compressor, a condenser, an expansion valve, an evaporator, and the like, and is constructed in the same manner as a refrigeration cycle. By transferring heat between indoor and outdoor by liquefaction and vaporization of circulating refrigerant, The refrigerant absorbs the heat of the room in the evaporator and discharges heat to the outside through the condenser to cool the room. When the refrigerant operates as a heating system, the refrigerant absorbs the heat from the outside of the evaporator And the heat pump system is configured to heat the room by discharging heat to the room through the condenser. The heat pump system adds a direction switching valve in the cycle to control the circulation direction of the refrigerant in the forward or reverse direction, It can be operated by heating in winter, In such a case, the roles of the evaporator and the condenser change each other. In the summer, the evaporator serves as an indoor unit and the condenser serves as an outdoor unit. In the winter, the evaporator serves as an indoor unit and the evaporator serves as an outdoor unit. And the air is cooled and heated.

However, the order in which the energy is transferred from the ordinary heat pump system is a cold / heating operation utilizing only the evaporation heat for cooling or the condensation heat for heating by applying the refrigerant compression power to the reverse Rankine cycle, There is a problem in that the kinetic energy of the fluid refrigerant flowing in the piping during the operation of the pump can not be used at all and is left unused.

To solve the above problem, Japanese Patent No. 0955235 entitled " Power Generation Device Using Heat Pump "has been conventionally proposed. As shown in Figs. 2 and 3, a compressor 1 for compressing a low temperature gas, an expansion valve 3 for lowering the pressure of the refrigerant discharged from the condenser and an evaporator 4 as a low temperature heat exchanger, An expansion turbine 5 replacing an expansion valve 3 constitutes a power generation device coupled to a generator 7 by a coupling 8 and supplied to the heat pump device drive power such as an energizer through an inverter 8 With a power-saving heat pump system configuration,

This is a power generation device for generating electricity by using the heat generated by the heat pump and the energy of the refrigerant remaining in the cooling and heating operation during the operation of the heat pump and the heat of the air sucked in the evaporation process, And a coupling (8) for transferring the rotational force of the expansion turbine (5) to the generator by using a magnetic force. In the power generator configuration, the expansion valve provided in the conventional heat pump heating and cooling system is replaced by an expansion turbine 5 and a generator 8 connected to the generator 6 by a coupling 8, the expansion turbine is driven by the low-temperature high-pressure refrigerant flow of the heat pump cooling and heating system to obtain rotational power, and the driving force obtained from the expansion turbine is transmitted to the generator The heat pump system is composed of a heat pump system Low-temperature power generation using refrigerant gas expansion power is a great value as one of alternative energy because it can supply energy for 24 hours only by heat source. Heat pump system It is used to drive heat pump system by generating electricity by operating expansion turbine during simultaneous cooling and heating It is possible to install the turbine and the generator in the outdoor unit of the heat pump through a simple structure change by using the heat pump driving power with the inexpensive own production electric power and to save energy and environment, There is a problem in that the generation efficiency is low due to the lack of dynamic stability in which the generator is separated and formed so that the structure is complicated and the structural stability such as the wheel balance is poor and is not economical and noise and vibration are generated.

That is, in the prior art, since the turbine and the generator are rotated at a high speed in a state where they are coupled in the axial direction by the coupling force of the coupling as a fastening member, dynamic characteristics and structural stability are weak due to vibration between the members during turbine or generator operation And turbine wheel balancing becomes a problem.

Accordingly, the present inventor has eliminated the discrete coupling type power generation device in which the turbine and the generator are coupled by a coupling, which is low in structural stability and power generation efficiency, so that the turbine and the generator are integrally combined, High efficiency heat pump integrated with turbine that can obtain high efficiency output with economical, safe and dynamic characteristics. By developing a turbine generator for heating and cooling system, it can be easily combined with existing heat pump cooling and heating system and generated from turbine without deteriorating heat pump performance. A turbine generator for a heat pump heating and cooling system of the present invention was developed as a new and renewable energy device for generating and recycling electricity as a shaft power of a turbine capable of efficiently recovering waste energy to prevent heat loss and performing high efficiency power generation .

.

As described above, the conventional turbine-generator couple-coupled power generation apparatus has various problems,

A single heat pump system produces electricity by operating a turbine during simultaneous heating and cooling. It is a complex system that is complicated in structure to realize energy saving and environment friendly heat pump cooling and heating system. A turbine-integrated turbine generator that does not have a power generation system that combines a generator with a coupling is formed, and the turbine generator thus formed is efficiently linked to a heat pump cooling and heating system to efficiently recover waste energy that is lost during the operation of the heat pump system to prevent heat loss And by performing high-efficiency power generation, it is possible to improve power generation efficiency, reduce energy consumption, and minimize operating cost, thereby creating a turbine generator for a heat pump cooling and heating system suitable for the application characteristics of power generation using refrigerant gas. It will be solved.

As described above, the present invention has been made to solve the above-mentioned problems,

As a turbine generator for a heat pump cooling and heating system, an expansion valve of a heat pump cooling and heating cycle is replaced by an expansion turbine, a generator is coupled to an expansion turbine by coupling, and the expansion turbine is driven by a low temperature high pressure refrigerant flow of the heat pump cooling and heating system, And the electric power is generated by transferring the driving force obtained from the expansion turbine to the electric generator to generate electricity. However, since the structure is complicated due to the complicated structure, the electric power generator for the heat pump heating and cooling system, which is uneconomical,

The present invention provides a turbine generator having a turbine-integrated type structure in which a turbine and a generator are integrally coupled to each other, so that the structure is simple and easy to manufacture and lightweight can be achieved, The present invention provides a turbine generator for a heat pump heating and cooling system having a turbine and a generator-integrated structure capable of continuously generating electricity with high efficiency in connection with an air-conditioning system.

That is, the turbine generator for a heat pump cooling and heating system of the present invention is economical and safe due to the simplification of the generator and the miniaturization of the facility because the turbine and the generator are integrally combined, And the turbine and the generator are integrally joined to each other to separate the turbine and the generator. As compared with the conventional structure in which the turbine and the generator are integrally combined, the vibration is attenuated and the structural stability due to the improvement of the fastening force, It is possible to create a comfortable environment with low noise.

In addition, if the turbine generator according to the present invention is used for power generation, the heat pump system can generate power itself, thereby reducing power charges, realizing low-cost self-power generation, It is energy-saving and environment-friendly.

Particularly, the present invention is economical because it is possible to mount the turbine generator of the present invention to an outdoor unit of a heat pump system device through a simple structure change, and also in terms of energy efficiency, the electricity consumption is low due to feedback by self- So that the energy efficiency can be increased.
