fig. 1 is a block diagram of a distributed energy co-generation system according to an embodiment of the invention.
Detailed Description
The features and technical effects of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and exemplary embodiments, which disclose a distributed energy co-generation system for realizing energy cascade utilization, directly serving a user end, and reducing remote energy transmission. It is noted that like reference numerals refer to like structures and that the terms "first", "second", "upper", "lower", and the like as used herein may be used to modify various structures. These modifications do not imply a spatial, sequential, or hierarchical relationship to the structures being modified unless specifically stated.
As shown in fig. 1, the distributed energy co-generation system according to the preferred embodiment of the present invention includes a plurality of user-side energy co-generation devices, which are respectively coupled to a plurality of user-side air conditioners and are disposed in a room where a user is located, such as a living room, a kitchen, a bedroom or a bathroom, or in any other room where indoor temperature control is required. The user-side air conditioner may be a client device (including a blower, an exhaust fan, etc.) of a central air conditioner installed in a building in a unified manner, may be a floor heating or cooling pipeline (filled with a heat exchange medium such as water) laid under a floor or floor tiles in a user's home, or may be a vertical cabinet air conditioner. Herein, "coupled" refers to the communication, flow or exchange between each customer premise energy co-generation device and the respective customer premise air conditioner, and is not limited to electrical, thermal or fluid communication.
As shown in fig. 1, each customer-side energy cogeneration device includes a gas turbine, a waste heat boiler, and an absorption chiller controlled by a controller. The gas turbine is, for example, a small or micro gas turbine specially installed indoors, receives natural gas input from a natural gas pipeline by a household, and ignites the natural gas in the gas turbine to drive an impeller to drive a rotor to generate power. The power generated by the gas turbine is directly connected to a local grid in a building where users are located via a power output port, and the power generated by the gas turbine is rectified to supply power to electrical load devices of the users in the building, such as a lighting system, an electromagnetic cooking device, a network communication device, an audio-visual entertainment device, and a backup power storage device (battery). Therefore, when the external power grid voltage is unstable or the power is cut off for a short time, the user can still use the electric energy uninterruptedly, the user experience is optimized, and the safety of the system is improved. The exhaust-heat boiler may be an exhaust-heat device thermally connected in series with the gas turbine, and heat medium such as water in the boiler is heated by using high-temperature exhaust gas discharged from the gas turbine, so that the exhaust heat in the power generation process of the gas turbine is fully utilized. In addition, a separate gas boiler can be used to replace the waste heat boiler (i.e. in thermal parallel with the gas turbine), and natural gas can be directly combusted to heat the heating medium in the boiler, so as to obtain enough heat. The absorption type refrigerator is in thermal series connection with a waste heat boiler (or a gas boiler), absorbs a part of dissipated heat from the waste heat boiler, uses the heat as self-refrigerating energy, cools a refrigerant (water or alcohol) in the refrigerator, and conveys the refrigerant to a user side air conditioner through a refrigerating port for refrigerating a room where a user is located when the temperature is high in summer. On the other hand, the heat exchanger (heat sink, heat dissipation coil, etc.) is indirectly thermally coupled to the exhaust-heat boiler, for example, under the control of the controller via an adjustable heat conduction member (e.g., a displaceable heat dissipation copper plate, a PTC semiconductor refrigeration/heating device, a heat pipe filled with a heat medium and having a valve, etc.) to be thermally coupled to the boiler, and absorbs another portion of the boiler heat to heat the heat medium (water) for delivery to the user-side air conditioner through the heat supply port for heating the room where the user is located at a low temperature in winter. Preferably, the user side energy source combined supply device is internally provided with a three-way valve, a first input end is connected with a refrigerant outlet of the absorption refrigerator, a second input end is connected with a heat medium outlet of the heat exchange device, an output end is connected with a user side air conditioner, and the type of the supplied medium is switched according to the ambient temperature of a user room under the control of the controller.
The controller sends respective control instructions to the gas turbine, the waste heat boiler and the absorption chiller according to environmental data collected by the sensor from the air conditioner at the user side, and the respective control instructions are used for controlling the power distribution of each device. The sensor may comprise a thermometer for measuring the air temperature in the room in which the user is located. The sensor may comprise an infrared sensor, the user directly measuring the body temperature of the user. Further preferably, the sensors may also include a hygrometer, a pressure gauge, and a gas sensor for measuring the humidity, the pressure, and the atmosphere composition of the room where the user is located (for example, preventing the leakage of combustion exhaust gas, natural gas, and the like), so as to provide a basis for the controller to control the power of each component. Further, the sensors may also include a voltmeter for measuring the power stability of the room in which the user is located, and a flow rate meter for measuring the air flow condition of the room in which the user is located.
When the indoor temperature or the body temperature of the user is lower than the lower limit value (for example, the room temperature is lower than 18 ℃ or the body temperature is lower than 36.5 ℃), the controller commands the gas turbine to increase the natural gas intake amount to reduce the electric output power, and simultaneously, the heat exchange device is started and the absorption refrigerator is stopped, namely, the waste heat or waste heat supplied to the waste heat boiler is increased to further increase the heat carried by the heat medium output through the heat supply port, so that the heating or warming capacity of the air conditioner at the user end is finally improved, and the air temperature is increased until the indoor temperature or the body temperature of the user is higher than or equal to the lower limit value (for example, the indoor air temperature is higher than 18 ℃ or the body temperature is higher than 36..
When the indoor temperature or the body temperature of the user is higher than the upper limit value (for example, the room temperature is higher than 28 ℃ or the body temperature is higher than 38 ℃), the controller commands the gas turbine to increase the natural gas suction amount to reduce the electric output power, and simultaneously the absorption refrigerator is started to stop the heat exchange device, namely, the waste heat or the waste heat supplied to the waste heat boiler is increased to further increase the heat carried by the refrigerant output through the refrigeration port, so that the refrigeration capacity of the air conditioner at the user end is finally improved, and the air temperature is reduced until the indoor temperature or the body temperature of the user is lower than or equal to the upper limit value.
When the indoor temperature or the body temperature of the user is greater than or equal to the lower limit value and less than or equal to the upper limit value (further preferably, when voltage fluctuation or power failure of an external power grid or an indoor power supply line is detected), the controller commands the gas turbine to increase the electric output power, and simultaneously deactivates the absorption chiller and the heat exchange device, namely in spring or autumn with proper temperature, the air conditioner is not activated any more, and the full power generation is performed for stabilizing the voltage fluctuation or supplementing power supply.
When the sensor detects that the indoor humidity is greater than a threshold and the airflow velocity in the room is greater than a threshold, such as a kitchen scene with ventilation but high humidity, the controller may command the absorption chiller to be activated and the heat exchange device to be deactivated, thereby chilling the kitchen floor for a short period of time to promote condensation of water vapor in the indoor air to avoid discomfort to the person.
When the sensor detects that the indoor humidity is greater than the threshold value and the airflow speed in the room is less than the threshold value, for example, in a bathroom scene with insufficient air circulation and high humidity, the controller commands the intermittent start of the absorption refrigerator, the complete stop of the heat exchange device and the intermittent start of the exhaust fan (which can be integrated in the air conditioning device at the user end or can be additionally attached), so that the moisture is condensed and discharged, meanwhile, the temperature in the bathroom is not reduced, and the cold catching of people is avoided.
When the atmosphere composition detected by the sensor indicates that the natural gas is insufficiently combusted or leaked, the controller commands the gas turbine, the waste heat boiler, the absorption refrigerator and the heat exchange device to be stopped, and simultaneously starts the exhaust fan to exhaust waste gas, so that personnel are prevented from being damaged due to excessive waste gas suction. Preferably, the controller or sensor will also alert a wearable device (e.g. a smart band or watch) that the user is carrying with him at this time. The alert may be a visual alert such as an alarm symbol, image or text of a predetermined color and/or graphic displayed on the display screen. The alarm may also be an audible alarm such as a whistle, drum beat, or other preset music.
Preferably, when the environment where the person is located is noisy (for example, the background noise decibel of the environment detected by the sensor exceeds the threshold value, or the lighting condition exceeds the threshold value), for example, in a kitchen, a bar, a restaurant, an entertainment place, etc., the commonly used visual alarm manner is easily affected by the ambient light source without being obvious, or the audible alarm manner is easily covered by the ambient noise, so that the user cannot know the alarm information in the first time. Therefore, the preferred embodiment of the application is further additionally provided with a tactile alarm which can be wearable equipment worn by a user, such as a bracelet, a collar, a pendant and the like, and the eccentric wheel is driven by the built-in motor to generate regular vibration so as to send out the tactile alarm. In the case of a noisy environment, the user's hearing, vision, and touch may be somewhat reduced by the clothing wrapping. For this purpose, the tactile alarm can also be a pain stimulus device worn close to the body, such as a lancet or an electrode, which ensures timely and effective alarm by using the sensitivity of the user's body to the pain.
According to a preferred embodiment of the invention, the primary energy is based on gaseous fuel and the secondary energy is based on cogeneration distributed at the user end. The natural gas is utilized to do work through combustion to generate high-grade electric energy through the internal combustion engine, and then the low-grade heat energy discharged by the power generation equipment is fully utilized to realize the cascade utilization of energy due to heat supply and refrigeration of waste heat equipment, so that the energy is directly served to a user side, and the remote transmission of the energy is reduced.
According to the distributed energy co-generation system provided by the embodiment of the invention, the energy co-generation device is directly arranged at the user side, so that efficient energy cascade utilization is realized, long-distance energy transmission is reduced, and the distributed energy co-generation system is low-carbon, environment-friendly, efficient and safe.

In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the disclosed apparatus and methods will include all embodiments falling within the scope of the present invention.
