Description

Technical Field

[0001] The present invention relates to the field of air - conditioning temperature regulation, and particularly to a cooling, heating and power cogeneration regulation system and method based on the perceived temperature. Background Art

[0002] The statements in this section merely provide background technical information related to the present disclosure and do not necessarily constitute prior art.

[0003] A cooling, heating and power cogeneration unit refers to a unit that uses natural gas as the main fuel to drive gas - powered generation equipment such as gas turbines, micro gas turbines or internal combustion generators. The generated electricity is supplied to users, and the waste heat discharged after the system generates electricity is used for heating and cooling users through waste heat recovery and utilization equipment (such as waste heat boilers or waste heat direct - fired machines). In this way, the primary energy utilization rate of the entire system is greatly improved, and the cascade utilization of energy is realized. It can also provide grid - connected power for energy complementarity, and the economic benefits and efficiency of the entire system are correspondingly increased.

[0004] Currently, both cooling, heating and power cogeneration units and large - capacity air - conditioning systems adopt the regulation method based on ambient temperature. According to temperature - measuring elements such as built - in thermal resistors, differential regulation is carried out by setting a specific temperature. However, temperature cannot fully reflect the human body's perception of the warmth or cold of the environment. For different latitudes, different humidities and wind speeds, at the same temperature, the human body's perception of warmth and cold varies greatly. If the cooling, heating and power cogeneration unit is regulated in the conventional way, it will cause a great waste of energy. Summary of the Invention

[0051] The present invention will be described in detail below with reference to the embodiments shown in the drawings. It should be noted that these embodiments are not intended to limit the present invention, and any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present invention.

[0052] At present, both the combined cooling, heating and power supply system and the large-capacity air-conditioning system adopt the regulation method based on ambient temperature. According to the built-in temperature measuring elements such as thermal resistors, differential regulation is performed by setting a specific temperature. However, temperature cannot fully reflect the human perception of the environment's cold and warmth. For different latitudes, different humidity and wind speeds, at the same temperature, the human perception of cold and warmth varies greatly, which will greatly cause energy waste.

[0053] Please refer to Figure 1 , Figure 1 is a schematic diagram of a combined cooling, heating and power supply regulation system based on sensed temperature provided by an embodiment of the present invention Figure 1, A combined cooling, heating and power (CCHP) regulation system based on perceived temperature provided by an embodiment of the present invention includes a perceived temperature acquisition module, a main regulator, and a sub-regulator. Among them, the perceived temperature acquisition module acquires a perceived temperature value; the main regulator performs a deviation operation on the set temperature and the ambient temperature to obtain a first deviation operation result, and the main regulator adjusts the CCHP unit according to the first deviation operation result; the sub-regulator is connected to the perceived temperature acquisition module and the main regulator. The main regulator outputs an output value to the sub-regulator, and the perceived temperature acquisition module outputs a perceived temperature value to the sub-regulator. The sub-regulator performs a deviation operation on the output value output by the main regulator and the perceived temperature value output by the perceived temperature acquisition module to obtain a second deviation operation result, and the sub-regulator adjusts the CCHP unit according to the second deviation operation result.

[0054] It should be noted that for a CCHP regulation system based on perceived temperature provided by an embodiment of the present invention, the regulation object is not limited to regulating the CCHP unit. The CCHP unit can also be replaced with a large-capacity air conditioner, that is, a CCHP regulation system based on perceived temperature provided by an embodiment of the present invention can also regulate a large-capacity air conditioner. In addition, a CCHP regulation system based on perceived temperature provided by an embodiment of the present invention has undergone tests in a complete cooling and heating season, and the perceived cooling and heating are good. Furthermore, the main regulator outputs an output value to the sub-regulator. This output value refers to the adjusted space temperature after PI regulation of the deviation between the set temperature and the ambient temperature. The adjusted space temperature and the perceived temperature value output by the perceived temperature acquisition module are used to perform a deviation operation to obtain a second deviation operation result, and the sub-regulator adjusts the CCHP unit according to the second deviation operation result.

[0055] Based on the regulation of the CCHP by the main regulator in an embodiment of the present invention, the perceived temperature value acquired by the perceived temperature acquisition module is used as a parameter, and the CCHP unit is adjusted by the sub-regulator, which not only greatly improves the comfort but also avoids actual energy waste, and has a good energy-saving effect.

[0056] In addition, an embodiment of the present invention uses the perceived temperature of the perceived temperature acquisition module as the regulation object. On the basis of the original regulation using the ambient temperature, the sub-regulator delays the regulation of the CCHP regulation unit. This greatly improves the control accuracy and the response speed of the CCHP regulation system. The delayed regulation in an embodiment of the present invention is because after the main regulator outputs an output value to the sub-regulator, the sub-regulator makes a deviation based on the output value and the perceived temperature value. There is a time difference between the regulation of the main regulator and the sub-regulator, and the sub-regulator performs rapid regulation only after the main regulator has regulated. Therefore, the sub-regulator delays the regulation of the CCHP regulation unit.

[0057] Please refer to Figure 2 , Figure 2The principle block diagram of a cooling, heating and power cogeneration regulation system based on the perceived temperature provided by the embodiments of the present invention Figure 2 For a cooling, heating and power cogeneration regulation system based on the perceived temperature according to the embodiments of the present invention, in addition to including a perceived temperature acquisition module, a main regulator and a sub-regulator, it further includes an automatic regulation cut-out module. The automatic regulation cut-out module is connected to the sub-regulator. When the second deviation calculation result is greater than 10°C, the automatic regulation cut-out module is turned on, and the automatic regulation cut-out module cuts out the sub-regulator from the cooling, heating and power cogeneration unit. In the embodiments of the present invention, when the second deviation calculation result is greater than 10°C, the sub-regulator does not need to regulate the cooling, heating and power cogeneration unit, and the automatic regulation cut-out module cuts out the sub-regulator from the cooling, heating and power cogeneration regulation system, and manually adjusts the cooling, heating and power cogeneration regulation system.

[0058] Please refer to Figure 3 , Figure 3 The figure of a cooling, heating and power cogeneration regulation system based on the perceived temperature provided by the embodiments of the present invention. The automatic regulation cut-out module of the embodiments of the present invention is Figure 3 The lower left and middle right parts in cooperate to complete cutting out the sub-regulator from the cooling, heating and power cogeneration unit. The automatic regulation cut-out module is also connected to the main regulator. When the automatic regulation cut-out module is turned on, the automatic regulation cut-out module cuts out the main regulator from the cooling, heating and power cogeneration unit; the cooling, heating and power cogeneration unit is connected with a manual regulation module, and the manual regulation module regulates the cooling, heating and power cogeneration unit.

[0059] In practical applications, when the second deviation calculation result of the embodiments of the present invention is greater than 10°C, the automatic regulation cut-out module cuts out the sub-regulator from the cooling, heating and power cogeneration unit. Manually adjust the cooling, heating and power cogeneration unit. It should be noted that the cooling, heating and power cogeneration unit of the embodiments of the present invention can be automatically regulated by both the main regulator and the sub-regulator, and can also be manually regulated by humans. When manually regulating, the sub-regulator can be cut out from the cooling, heating and power cogeneration unit and then manually regulated. When the preset conditions are met, that is, in extreme cases (for example, the main regulator and manual regulation cannot quickly adjust the cooling, heating and power cogeneration unit to the indoor required temperature), the sub-regulator and the main regulator can also be cut out from the cooling, heating and power cogeneration unit, and after manual regulation, the main regulator and the sub-regulator are connected to the cooling, heating and power cogeneration unit again.

[0060] The general formula for the current meteorological perceived temperature is At=1.07T+0.2e-0.65V-2.7, e=RH / 100*6.105*exp(17.27T / (237.7+T)). Among them, AT is the perceived temperature (℃), T is the air temperature (℃), e is the water vapor pressure (hPa), V is the wind speed (m / sec), and RH is the relative humidity (%). The perceived temperature is mainly based on the factors of temperature, humidity, and wind speed. The use of this formula to calculate the effect of seasons, latitudes, and rainy days on people's perceived comfort temperature is small. In summer, the perceived temperature is positively correlated with air humidity and wind speed, and in winter, the perceived temperature is negatively correlated with air humidity and wind speed. By adding a correction coefficient, the perceived temperature is corrected for different latitudes and seasonal temperatures to achieve a suitable perceived temperature.

[0061] The calculation formula of the perceived temperature preliminarily proposed in the embodiment of the present invention is Ts=A×[1-0.3*sin(Ψ-23.5)]-0.3×cos[15×(M-1)] (where Ψ is the dimension, M is the month, and A is the average temperature of the human body). Therefore, based on the above-mentioned public solution, the perceived temperature acquisition module of the embodiment of the present invention includes an optimal comfort calculation module; the optimal comfort temperature calculation formula of the optimal comfort calculation module is:

[0062] Ts=Ax[1-0.3*sin(ψ-23.5)]-0.3xcos[15x(M-1)] Formula (1)

[0063] In formula (1), ψ is the dimension, M is the month, A is the average temperature of human body temperature, and Ts is the optimal comfortable temperature. According to actual experience, the preferred value of A in the embodiment of the present invention is human body temperature*0.618. The optimal comfortable temperature is calculated according to the golden ratio. According to the golden ratio, since the body temperature of children is between 36.7-37.7°C, the average temperature of children is 37.2°C, and the optimal comfortable temperature is the average temperature 37.2*0.618≈23°C. The body temperature of adults is generally between 36-37.3°C, and the average temperature of adults is 36.65°C. According to the golden ratio, the optimal comfortable temperature is the average temperature 36.65*0.618=22.6°C. In addition to the optimal comfort calculation module, the body temperature acquisition module of the embodiment of the present invention also includes a body temperature value calculation module; the body temperature value calculation module calculates the body temperature value according to the high temperature segment or the low temperature segment through relevant parameters according to different groups; the relevant parameters include the average air temperature, the most suitable temperature, the relative humidity, and the most suitable humidity. When the average air temperature is greater than the most suitable temperature and the relative humidity is greater than the most suitable humidity, the body temperature value calculation module is processed according to the high temperature segment; when the average air temperature is less than the most suitable temperature and the relative humidity is greater than the most suitable humidity, the body temperature value calculation module is processed according to the low temperature segment.

[0064] According to children's gathering areas (such as children's hospitals, etc.), calculate the optimal comfort temperature Ts = 23×[1 - 0.3*sin(Ψ - 23.5)] - 0.3×cos[15×(M - 1)] (where Ψ is the latitude and M is the month). When the air temperature is higher than Ts, it is processed as the high-temperature section; otherwise, it is processed as the low-temperature section. Among them, the humidity amplifies the heating and cooling effects in a non-linear form at the high and low temperature sections with Ts as the boundary. The most comfortable humidity is 50% when there is no precipitation and 61.8% when there is precipitation. Moreover, low humidity has little impact on the human body, but the impact of high humidity on the human body shows an exponential change with the increase in temperature. That is, due to high humidity in summer inhibiting the body's heat dissipation, people feel stuffy, and high humidity in winter makes people feel cold and damp. The main effect of wind speed is to cool down, and the most suitable wind speed for the human body is 2m / s -1 , since the impact of low humidity on the human perception is not as significant as that of high humidity, it is ignored.

[0065] Therefore, in addition to the above-mentioned optimal comfort calculation module, the perceived temperature acquisition module of the embodiment of the present invention further includes a perceived temperature value calculation module; the perceived temperature value calculation module calculates the perceived temperature value according to different groups through relevant parameters in the high-temperature section or the low-temperature section. The relevant parameters include the average air temperature, the most suitable temperature, the relative humidity, and the most suitable humidity. When the average air temperature > the most suitable temperature and the relative humidity > the most suitable humidity, the perceived temperature value calculation module processes it as the high-temperature section; when the average air temperature < the most suitable temperature and the relative humidity > the most suitable humidity, the perceived temperature value calculation module processes it as the low-temperature section;

[0066] Among them: The calculation formula for the perceived temperature value calculation module to process in the high-temperature section is:

[0067] Tg = Ta + A{exp[0.05(Ta - Ts)(RH - RHs)] - 1} - 0.3(Ta - Ts)V Formula (2)

[0068] In Formula (2), Tg is the perceived temperature, Ta is the average air temperature, Ts is the optimal comfort temperature, RH is the relative humidity, RHs is the most suitable humidity, and V is the average wind speed;

[0069] Among them: The calculation formula for the perceived temperature value calculation module to process in the low-temperature section is:

[0070] Tg = Ta - A{exp[0.013(Ta - Ts)(RH - RHs)] + 1} - 0.01(Ts - Ta)V Formula (3)

[0071] In Formula (3), Tg is the perceived temperature, Ta is the average air temperature, Ts is the optimal comfort temperature, RH is the relative humidity, RHs is the most suitable humidity, and V is the average wind speed.

[0072] In practical applications, for the perceived temperature in the embodiments of the present invention, when Ta > Ts and RH > RHs, it is in the high-temperature section, and the calculation method is as follows: Tg = Ta + A{exp[0.05(Ta - Ts)(RH - RHs)] - 1} - 0.03(Ta - Ts)V; when Ta < Ts and RH > RHs, it is in the low-temperature section, and the calculation method is as follows: Tg = Ta - A{exp[0.013(Ta - Ts)(RH - RHs)] + 1} - 0.01(Ts - Ta)V. Where Tg is the perceived temperature, Ta is the average air temperature, V is the average wind speed, Ts is the optimal comfort temperature, RH is the relative humidity, RHs is the most suitable humidity, 61.8% when there is precipitation and 50% when there is no precipitation, and the humidity term has no effect when there is no precipitation.

[0073] It should be noted that currently for large hospitals or commercial complexes, since only the average temperature in the hospital or complex rooms is considered for aisles, corridors, etc., temperature sensors are configured at the center point of the room top and around the space to measure the temperature. The installation height of the surrounding temperatures is 1.7 m, and the average value of five measurement points is taken as the average temperature of this room. For different types of buildings, several rooms are selected for weighted average processing, and the weights are calculated based on the ratio of the designed pedestrian flow per unit area. Therefore, when calculating the average air temperature Ta in the embodiments of the present invention, several rooms are selected for weighted average processing, and the weights are calculated based on the ratio of the designed pedestrian flow per unit area.

[0074] Please continue to refer to Figure 3 , for the heating and cooling demands of large complexes, it can be approximated as a large time-delay link during regulation. For the regulation of large time-delay links, a cascade control system is adopted. The secondary regulator uses the perceived temperature as the process variable of the secondary regulator, which can effectively improve the influence of the perceived temperature disturbance on the system, enabling the control system to respond in a timely manner and improving the regulation accuracy of the system. In practical applications, the primary regulator in the embodiments of the present invention is a reverse regulator, and the primary regulator linearly regulates the combined cooling, heating, and power generation unit. Please continue to refer to Figure 3 , the primary regulator in the embodiments of the present invention is a reverse regulation, which uses the deviation between the set temperature and the ambient temperature for PI regulation. The output value is deviated from the perceived temperature, and the secondary regulator is used for rapid regulation to respond in a timely manner to the rapid change of the perceived temperature. When the primary regulator cannot adjust the combined cooling, heating, and power generation unit to the appropriate temperature, the combined cooling, heating, and power generation unit is switched out of automatic regulation, and after manually adjusting the combined cooling, heating, and power generation unit, the primary regulator and the secondary regulator are used for automatic regulation again.

[0075] The embodiments of the present invention use the perceived temperature as the regulation object of the combined cooling, heating, and power generation unit or large-capacity air conditioner. In winter, summer, or rainfall periods, it can be better regulated according to the actual temperature demand, greatly improving the comfort level, and being able to avoid actual energy waste, having a good energy-saving effect.

[0076] Based on the above-mentioned disclosed cold, heat and power cogeneration regulation system according to the perceived temperature, please refer to Figure 4 , Figure 4 which is a flowchart of a cold, heat and power cogeneration regulation method provided by an embodiment of the present invention. An embodiment of the present invention also provides a cold, heat and power cogeneration regulation method according to the perceived temperature, including:

[0077] Step 1: Obtain the perceived temperature value.

[0078] Obtaining the perceived temperature value in Step 1 specifically includes:

[0079] The formula for the optimal comfort temperature of the optimal comfort operation module is:

[0080] Ts = Ax[1 - 0.3*sin(ψ - 23.5)] - 0.3xcos[15x(M - 1)] Formula (1)

[0081] In Formula (1), ψ is the dimension, M is the month, A is the average body temperature, Ts is the optimal comfort temperature. Optionally, in actual application, the value of A is the body temperature * 0.618;

[0082] The perceived temperature value operation module calculates the perceived temperature value according to different groups by relevant parameters in the high-temperature section or the low-temperature section. The relevant parameters include the average air temperature, the most suitable temperature, the relative humidity, and the most suitable humidity. When the average air temperature > the most suitable temperature and the relative humidity > the most suitable humidity, the perceived temperature value operation module processes it in the high-temperature section; when the average air temperature < the most suitable temperature and the relative humidity > the most suitable humidity, the perceived temperature value operation module processes it in the low-temperature section. Among them, the calculation formula for processing in the high-temperature section is:

[0083] Tg = Ta + A{exp[0.05(Ta - Ts)(RH - RHs)] - 1} - 0.3(Ta - Ts)V Formula (2)

[0084] In Formula (2), Tg is the perceived temperature, Ta is the average air temperature, Ts is the most suitable temperature, RH is the relative humidity, RHs is the most suitable humidity, V is the average wind speed, where Ta > Ts and RH > RHs;

[0085] Among them, the calculation formula for the perceived temperature value operation module to process in the low-temperature section is:

[0086] Tg = Ta - A{exp[0.013(Ta - Ts)(RH - RHs)] + 1} - 0.01(Ts - Ta)V Formula (3)

[0087] In formula (3), Tg is the perceived temperature, Ta is the average air temperature, Ts is the optimal comfort temperature, RH is the relative humidity, RHs is the most suitable humidity, and V is the average wind speed. Among them, Ta < Ts and RH > RHs.

[0088] Step 2: The main regulator performs a deviation operation on the set temperature and the ambient temperature to obtain a first deviation operation result, and the main regulator adjusts the combined cooling, heating and power supply unit once according to the first deviation operation result.

[0089] The air conditioner adjustment in the embodiment of the present invention does not adopt direct temperature adjustment, but adopts a calculation method of unconventional perceived temperature to accurately calculate the perceived temperature, avoiding inaccurate perceived temperature caused by the perceived temperature in winter, summer or rainfall periods.

[0090] Step 3: The secondary regulator performs a deviation operation on the output value of the main regulator and the perceived temperature value to obtain a second deviation operation result, and the secondary regulator adjusts the combined cooling, heating and power supply unit twice according to the second deviation operation result. The primary adjustment and secondary adjustment in the embodiment of the present invention are the same as the above-mentioned adjustment of the combined cooling, heating and power supply adjustment unit with a delay by the secondary regulator on the basis of the original adjustment using the ambient temperature. That is, after the main regulator outputs an output value to the secondary regulator, the secondary regulator makes a deviation based on the output value and the perceived temperature value. There is a time difference between the adjustment of the main regulator and the secondary regulator, and the secondary regulator only adjusts after the main regulator adjusts.

[0091] Step 3 of the embodiment of the present invention further includes: when the second deviation operation result is greater than 10 °C, the automatic adjustment cut-out module is turned on, and the automatic adjustment cut-out module cuts out the secondary regulator from the combined cooling, heating and power supply unit.

[0092] The embodiment of the present invention uses the perceived temperature as the adjustment object of the combined cooling, heating and power supply unit or large-capacity air conditioner. In winter, summer or rainfall periods, it can be better adjusted according to the actual temperature requirements, greatly improving the comfort level, and can avoid actual energy waste, having a good energy-saving effect. In addition, the adjustment system in the embodiment of the present invention adopts a cascade adjustment large-delay link to increase the adjustment response to disturbances (perceived temperature), effectively improving the adjustment accuracy.
