Description

Technical Field

[0001] The present invention relates to the technical field of air source heat pump energy saving, and in particular to an air source heat pump heating system. Background Art

[0002] When the air source heat pump is heating in winter, it needs to absorb heat from the outdoor air. When the outdoor air temperature is low or the humidity is too high, when the outdoor coil exchanges heat with the outdoor air, the coil fin temperature is lower than the dew point or freezing point of the outdoor air, condensation and frost will occur, increasing thermal resistance and affecting heat exchange efficiency. The heating capacity will decay by 10-23% during normal frosting, and by up to 45% during abnormal frosting. As the frost layer on the wall of the outdoor heat exchanger increases, the evaporation temperature of the outdoor heat exchanger decreases, the heating capacity of the unit decreases, the fan performance decays, the input current increases, and the heating performance coefficient decreases. In severe cases, the compressor will stop running, causing the unit to fail to work normally. At this time, the air source heat pump must enter the defrosting condition.

[0003] The existing mainstream defrosting methods include: shutdown defrosting, electric heating defrosting, hot gas bypass defrosting, reverse cycle defrosting, etc. Among them, reverse cycle defrosting is the most commonly used defrosting method. These defrosting methods are mainly completed through the principle of convection heat transfer. Looking at a large number of authorized invention patents, such as CN202010812135.3, CN202410863152.8, CN202010067342.0, CN202410812597.3, CN202010812135.3, CN202410595485.7, CN202410087392.3, etc., almost all of them use hot water heat exchange for defrosting. CN202410531217.9 uses mechanical friction to remove frost, but it will result in incomplete defrosting. Some also use optimized defrost mode strategies, such as CN202210467024.2, CN202111020818.6, CN201810615402.0, etc.

[0004] After reviewing relevant patents, no patents have been found that directly use radiation heat exchange to solve the defrosting or frost suppression problem. The present invention uses radiation heating to solve the defrosting or frost suppression problem. Specifically, it is infrared heating technology.

[0005] Infrared heating technology uses the infrared radiation emitted by infrared radiation elements to be directly converted into heat energy by the material. Its essence is infrared radiation heat transfer. The energy radiated by infrared heating technology is proportional to the fourth power of the radiation temperature. Compared with traditional heating methods, production efficiency is increased by 20% to 30%, electricity is saved by 30% to 50%, and other energy is saved by about 30%.

[0006] The electric energy used by infrared heating technology mainly comes from solar energy or wind energy. Solar energy or wind energy is green energy. Using solar energy or wind energy directly for infrared heating tubes, and then acting on the outdoor coil of the air source heat pump, it can increase the air temperature, inhibit frost, and expand the operating range of air source heat source heating, which will have great energy-saving potential.

[0014] Further, when the power detector detects that the power in the storage battery is lower than the power critical value and the charging detector detects that the charging speed of the photovoltaic power supply unit and the wind power supply unit to the storage battery is lower than the charging critical value, the central processor sends a charging signal to the third controller, and the third controller transmits the electric energy provided by the municipal cable to the storage battery through the third inverter; When the power detector detects that the power in the battery is higher than the power critical value or the charging detector detects that the charging speed of the battery by the photovoltaic power supply unit and the wind power supply unit is higher than the charging critical value, the central processing unit sends a stop charging signal to the third controller, and the third controller controls the electric energy to stop charging the battery.

[0036] As a further embodiment of the present application, the municipal power supply unit includes a municipal cable, a third controller and a third inverter; The input end of the third controller is electrically connected to the municipal cable, and the output end of the third controller is electrically connected to the input end of the third inverter and the electrical equipment respectively; The output end of the third inverter is electrically connected to the battery.

[0037] As a further embodiment of the present application, it also includes a power detector, a charging detector, a power supply detector and a central processing unit; The power detector is used to detect the power information in the battery; An input end of the charging detector is electrically connected to an output end of the first controller and an output end of the second inverter; The output end of the charging detector is electrically connected to the battery; The charging detector is used to detect the charging status of the battery by the photovoltaic power supply unit and the wind power supply unit; The input end of the power supply detector is electrically connected to the output end of the first inverter and the output end of the second controller, and is used to detect the power supply of the photovoltaic power supply unit, the wind power supply unit and the battery to the electrical equipment; The power detector, the charging detector and the power supply detector are all electrically connected to the central processor and transmit the data detected by each detector to the central processor; The central processing unit is electrically connected to the third controller.

[0038] As a further implementation of the present application, when the power detector detects that the power in the battery is lower than the power critical value and the charging detector detects that the charging speed of the photovoltaic power supply unit and the wind power supply unit to the battery is lower than the charging critical value, the central processor sends a charging signal to the third controller, and the third controller transmits the electric energy provided by the municipal cable to the battery through the third inverter; When the power detector detects that the power in the battery is higher than the power critical value or the charging detector detects that the charging speed of the battery by the photovoltaic power supply unit and the wind power supply unit is higher than the charging critical value, the central processing unit sends a stop charging signal to the third controller, and the third controller controls the electric energy to stop charging the battery.

[0044] When entering the winter mode, the electric energy generated by the photovoltaic power supply unit or the wind power supply unit is directly used by the infrared radiation heating device under the control of the power supply system.

[0045] By adopting the above technical solution, the present invention has the following beneficial effects: (1) The system integrates three power supply methods: photovoltaic, wind and municipal, ensuring stable power supply to electrical equipment in different weather and environments. This multi-source power supply design significantly improves the reliability and stability of the system and reduces the risk of heating interruption caused by failure of a single power supply method.

[0046] (2) Photovoltaic panels and wind turbines can make full use of natural energy to generate electricity, which not only reduces dependence on traditional energy but also improves energy efficiency. At the same time, through intelligent control, the system can give priority to the use of renewable energy for power supply, and automatically switch to municipal power supply when it is insufficient, thus achieving optimal use of energy.

This intelligent management method not only improves the operating efficiency of the system, but also reduces maintenance costs and extends the service life of the equipment.

[0048] (4) The modular design of the system makes it easy to replace and maintain the various power supply components and power-consuming equipment, and also facilitates expansion and upgrading according to actual needs. This design enables the system to adapt to heating scenarios of different scales and needs, improving the flexibility and scalability of the system.

[0049] (5) The system gives priority to using renewable energy for power supply, and reduces carbon emissions and energy consumption by efficiently utilizing energy during the heating process. This environmentally friendly and energy-saving design not only conforms to the current green development trend, but also reduces the user's operating costs.

[0050] Example 2 like Figure 1-2 As shown, the electrical equipment of an air source heat pump heating system provided in this embodiment includes an air source heat pump outdoor unit 1 and an infrared radiation heating device 2; The air source heat pump outdoor unit 1 includes a condenser 1-1; The condenser 1-1 comprises a coil 1-3 and a non-metallic hydrophobic fin 1-4; The coil 1-3 and the non-metallic hydrophobic fins 1-4 are also sprayed with an infrared absorbing coating; An infrared radiation heating device 2 is arranged outside the air inlet side of the condenser 1 - 1 .

[0051] The present application modifies the metal fins used in the prior art into non-metallic hydrophobic fins 1-4, thereby ensuring and improving the infrared absorption rate.

[0052] As a further embodiment of the present application, the air source heat pump outdoor unit 1 includes a metal frame 1-2; The coil 1-3 and the non-metallic hydrophobic fins 1-4 are arranged on the metal frame 1-2 of the air source heat pump outdoor unit; The infrared radiation heating device 2 comprises a non-metallic frame 2-1, a heating tube 2-2, an arc-shaped reflection plate 2-3 and an air inlet structural member 2-4; The non-metallic frame 2-1 is fixedly connected to the metal frame 1-2; The heating tube 2-2 and the arc-shaped reflection plate 2-3 are arranged on the non-metallic frame 2-1; The arc-shaped reflection plate 2-3 is arranged on a side of the heating pipe 2-2 away from the air source heat pump outdoor unit 1, and its arc-shaped opening direction is opposite to the heating pipe 2-2; The air inlet structural member 2-4 is arranged on an end of the non-metallic frame 2-1 away from the air source heat pump outdoor unit 1; The air inlet structural components 2 - 4 are air inlet louvers or grilles.

[0053] When an air source heat pump heating system disclosed in the present application is working, in order to ensure the heat absorption effect of infrared rays, the coils 1-3 and fins of the condenser of the air source heat pump need to be updated, a special infrared absorption coating is sprayed on the original coils 1-3, and the fins are replaced with non-metallic hydrophobic fins 1-4 with similar heat transfer coefficients, and a special infrared absorption coating is sprayed on the non-metallic hydrophobic fins 1-4.

[0054] The present invention mainly generates infrared heat radiation through the green energy supply infrared radiation heating device 2, a part of the infrared directly acts on the condenser 1-1 of the air source heat pump unit, a part of the infrared is reflected by the arc reflector 2-3 of the infrared radiation heating device 2 and acts on the condenser 1-1 of the air source heat pump unit, and a very small part acts on the metal frame 1-2 of the air source heat pump outdoor unit 1, and acts on the air in the area through conduction. Under the action of the three, the temperature of the condenser 1-1 can be higher than the freezing point or 5-10°C higher than the outdoor air dew point temperature, thereby inhibiting or reducing frost, or reducing the time and frequency of the unit itself needing to defrost, thereby ensuring the heating effect. The present invention only needs to modify the condenser 1-1, and the newly added system is integrated into the control system of the original equipment, with small changes, easy use, and high energy efficiency.

[0055] By adopting the above technical solution, the present invention has the following beneficial effects: (1) By spraying infrared absorbing coating on the coil and non-metallic hydrophobic fins of the condenser and installing an infrared radiation heating device, the system can more effectively absorb and utilize infrared thermal radiation, thereby improving the heating efficiency, allowing the temperature of the condenser to be maintained at a high level, effectively inhibiting frosting, reducing the time and frequency of unit defrosting, and thus ensuring a stable heating effect.

[0056] (2) The use of non-metallic hydrophobic fins and the spraying of infrared absorbing coatings not only improve the heat transfer coefficient of the condenser, but also enhance its ability to absorb infrared rays, allowing the system to make more full use of thermal energy and improve the overall energy efficiency ratio.

[0057] (3) Since the system can utilize heat energy more efficiently, unnecessary energy consumption is reduced. At the same time, since the frequency of frosting and defrosting is reduced, the maintenance cost of the unit is also reduced.

[0058] (4) This technical solution only involves modifying the condenser. The newly added system can be easily integrated into the control system of the original equipment, with minimal changes and easy use.

[0059] Example 3 like Figure 4 As shown, the air source heat pump heating system provided in this embodiment also includes a control system; The control system includes a psychrometric diagram database and a frosting area map; The air inlet side of the condenser is provided with an atmospheric pressure sensor and an outdoor air temperature and humidity sensor; The condenser is provided with a temperature sensor for detecting the temperature of the condenser; The central processing unit is electrically connected to the temperature sensor, the atmospheric pressure sensor and the outdoor air temperature and humidity sensor; The atmospheric pressure sensor is used to monitor outdoor pressure changes and transmit the monitoring data to the central processor in real time, and the central processor corrects the enthalpy-humidity diagram database according to the outdoor pressure change data; The outdoor air temperature and humidity sensor is used to detect outdoor temperature and humidity value data and outdoor temperature value data and transmit the detection data to the central processor in real time. The central processor combines the outdoor temperature and humidity value data, the outdoor temperature value data and the frosting area map to determine whether the current temperature and humidity falls within the frosting area; If it is in the frosting area, the central processor compares the condenser temperature data with the boundary value of the frosting area. If the data difference is less than the first temperature difference setting value (preferably 5 degrees Celsius), the infrared radiation heating device is operated at non-maximum power until the condenser temperature value minus the outdoor temperature value is greater than the second temperature setting value (preferably 6 degrees Celsius), and the operation is stopped; if the data difference is greater than the first temperature difference setting value (preferably 5 degrees Celsius), the infrared radiation heating device is operated at maximum power until the condenser temperature value minus the outdoor temperature value is greater than the second temperature setting value (preferably 6 degrees Celsius).

[0060] The air source heat pump heating system disclosed in the present application embeds a psychrometric diagram database and a frosting area map in the original control system when it is working. An atmospheric pressure sensor and an outdoor air temperature and humidity sensor are set on the air inlet side of the condenser of the air source heat pump, and a temperature sensor is set on the condenser of the air source heat pump, and the temperature sensor controls the start-up operation of the infrared radiation heating device. These newly added systems and the control and operation fault alarm of the infrared radiation heating itself are all incorporated into the original control system of the air source heat pump.

[0061] When the air source heat pump unit enters the heating mode in winter, the atmospheric pressure sensor monitors the outdoor pressure change and corrects the enthalpy-humidity diagram database. At the same time, the outdoor air temperature and humidity sensor detects the outdoor temperature and humidity values, and combines the frosting area map to determine whether the current temperature and humidity fall within the frosting area. If it is not in the frosting area, the temperature value on the condenser of the air source heat pump can be set and compared with the temperature sensor value. If the set value is not reached, the infrared radiation heating device is controlled to start and run. If the set value is reached, the infrared radiation heating device is stopped. This working condition can use green electricity to improve the energy efficiency ratio and energy utilization rate. For every 1°C increase, energy consumption is reduced by about 3-4%, thereby saving conventional electricity consumption. If it is in the frosting area, first compare the temperature feedback value on the condenser with the boundary value of the frosting area. If it is less than 5°C, the infrared radiation heating device can be used to make the temperature on the condenser of the air source heat pump higher than the outdoor air temperature by more than 6°C, so that the air source heat pump can quickly leave the frosting area and prevent the air source heat pump from entering the defrosting condition, thereby reducing the frequency of frosting. If it is greater than 5°C and frosting occurs, the infrared radiation heating device needs to be continuously operated at maximum power to increase the temperature on the condenser of the air source heat pump and cooperate with the defrosting condition of the air source heat pump, so as to quickly defrost, shorten the defrosting time, and minimize the adverse effects of defrosting.

[0062] By adopting the above technical solution, the present invention has the following beneficial effects: (1) By integrating the psychrometric database and the frost area map, the system can intelligently determine whether the current outdoor environmental conditions are in a frost-prone area. Combined with real-time temperature and humidity monitoring and condenser temperature feedback, the system can automatically adjust the power of the infrared radiation heating device, effectively preventing or reducing condenser frost and avoiding energy efficiency degradation caused by frequent defrosting.

[0063] (2) In non-frosting areas, the system precisely controls the condenser temperature and starts the infrared radiation heating device only when necessary, thus avoiding unnecessary energy consumption. In frosting areas, by intelligently adjusting the power of the heating device, the system can quickly increase the condenser temperature, reduce the defrosting time and frequency, and thus improve the overall energy efficiency and energy utilization of the system.

[0064] (3) The system can monitor the changes in outdoor atmospheric pressure in real time and modify the psychrometric chart database accordingly to ensure accuracy under different conditions. This design enhances the environmental adaptability of the system and enables it to operate efficiently.

[0065] (4) New system components and their control logic are integrated into the original control system, achieving unified fault warning and diagnosis functions. This helps to detect and deal with potential problems in a timely manner, reducing maintenance costs and downtime.

[0066] (5) The system makes full use of green power resources and optimizes control strategies to improve energy efficiency while reducing conventional power consumption.
