[0002] In recent years, along with the improvement of people's material life, people's requirements for indoor environment are getting higher and higher, and the radiant air conditioning system is developing rapidly. In the energy mode selection of the radiant air conditioning system, the air source heat pump occupies almost more than 95% due to its natural energy-saving advantage. The working principle of the air source heat pump is to absorb the outdoor heat into the indoor through the fins arranged on the outdoor unit. Therefore, the air source heat pump has a congenital defect that the heating capacity will rapidly decay with the decrease of outdoor temperature in winter, especially when the air humidity is relatively high and the fin temperature is too low to produce frost. When frost occurs, the heat pump needs to defrost the indoor temperature, which causes the heat pump to always divide a part of power for frequent defrosting, so that the water temperature in the water outlet pipe of the heat pump cannot reach the user's set temperature, and the heating effect is not satisfactory.

[0042] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0043] like Figure 1 As shown, an embodiment of this application discloses an energy-complementary radiant air conditioning device, including a heat pump 100, a radiant terminal 200, and a boiler 300. The heat pump 100 includes a first water supply pipe 110 and a first water return pipe 120. The heat pump 100 is connected to the inlet of the radiant terminal 200 through the first water supply pipe 110, and the heat pump 100 is connected to the outlet of the radiant terminal 200 through the first water return pipe 120. The boiler 300 includes a second water supply pipe 310 and a second water return pipe 320. The boiler 300 is connected to the first water supply pipe 110 through the second water supply pipe 310, and the boiler 300 is connected to the first water supply pipe 110 through the second water return pipe 320. The distance between the second water supply pipe 310 and the second water return pipe 320 on the first water supply pipe 110 is less than or equal to 5 times the diameter of the first water supply pipe 110.
[0044] Specifically, when the heat pump 100 system is normal heating, the refrigerant (i.e. coolant) is compressed into a high-temperature and high-pressure gas under the action of the compressor, enters the heat exchanger (condenser) of the outdoor unit to dissipate heat to the outside, and then enters the heat exchanger (evaporator) of the indoor unit after being reduced in pressure by the throttling device to absorb heat, thereby achieving indoor heating. The condenser is provided with fins, which are in full contact with the air outside to absorb heat from the air into the room. The heat pump 100 also has a plate heat exchanger, and the refrigerant absorbs heat through the plate heat exchanger and transfers it to the radiation terminal 200.
[0045] More specifically, the heat pump 100 includes a first water supply pipe 110, one side of which is connected to the plate heat exchanger in the heat pump 100, and the other side is connected to the water inlet of the radiation terminal 200. The heat pump 100 also includes a first return water pipe 120, one side of which is connected to the water outlet of the radiation terminal 200, and the other side is connected to the plate heat exchanger in the heat pump 100. The plate heat exchanger, the first water supply pipe 110, the first return water pipe 120, and the radiation terminal 200 form a closed loop to regulate the temperature in the room. The boiler 300 includes a second water supply pipe 310 and a second return water pipe 320, both of which are connected to the first water supply pipe 110, and the distance between the second water supply pipe 310 and the second return water pipe 320 on the first water supply pipe 110 is less than or equal to 5 times the diameter of the first water supply pipe 110. The second water supply pipe 310 and the second return water pipe 320 are close to each other on the first water supply pipe 110, and the purpose is to keep the pressure of the water supply point (i.e. the connection point of the second water supply pipe 310 and the first water supply pipe 110) and the return water point (i.e. the connection point of the second return water pipe 320 and the first water supply pipe 110) of the boiler 300 basically the same, achieving hydraulic balance. Because the distance between the water supply pipe and the return water point of the boiler 300 is small, the resistance between the two points is almost the same and can be ignored. Therefore, the second water pump built in the boiler 300 only needs to overcome the resistance between the second water pump outlet of the boiler 300 and the first water supply pipe 110, and the smaller the resistance, the less power the second water pump needs, and the heat loss of the second water pump in the second water supply pipe 310 is also reduced.
[0046] A first water pump is provided in the heat pump 100, and a second water pump is provided in the boiler 300. The flow rate of the first water pump is greater than or equal to 3 times the flow rate of the second water pump. The large difference between the flow rate of the first water pump and the flow rate of the second water pump is to reduce the influence of the second water pump in the boiler 300 on the water flow in the first water supply pipe 110, so that part of the water in the first water supply pipe 110 enters the boiler 300 for heating, and part of the water mixed with the heated water in the boiler 300 to reduce the fluctuation of the water temperature, avoid the water temperature fluctuation too large, and affect the stability of the radiation terminal 200 behind the water supply pipeline.
[0047] In one specific embodiment, the second water supply pipe 310 is provided with a one-way valve 330. When the second water pump in the boiler 300 is suspended, the water in the first water supply pipe 110 is prevented from flowing backward in the boiler 300.
[0048] In one specific embodiment, the energy-complementary radiant air conditioning device further comprises a double-cold-source integrated machine 400, which comprises a third water supply pipe and a third water return pipe, the third water supply pipe being connected to the first water supply pipe 110, and the third water return pipe being connected to the first water return pipe 120.
[0049] Specifically, the double-cold-source integrated machine 400 and the radiant terminal 200 are connected in parallel to the first water supply pipe 110 and the first water return pipe 120 of the heat pump 100. The water path of the double-cold-source integrated machine 400 is always open, and the water flow is 50% of the water flow in the first water supply pipe 110. The water path of the radiant terminal 200 is opened or closed according to the set temperature and the actual temperature of the room. In the fully open state, the water flow of the radiant terminal 200 is 50% of the water flow in the first water supply pipe 110. When the radiant terminal 200 is fully closed, the water flow in it is 50% of the water flow in the first water supply pipe 110.
[0050] In one specific embodiment, the radiant air conditioning device further comprises a heat pump 100 state detection device for detecting the actual working condition of the heat pump 100; a boiler 300 operating device for opening or closing the boiler 300 according to the input control signal; and a control device for sending a control signal to the boiler 300 operating device to control the boiler 300 operating device according to the control signal sent by the heat pump 100 state detection device.
[0051] Specifically, the heat pump 100 state refers to the frequency of the compressor of the heat pump 100 and the temperature of the outlet of the first water supply pipe 110 of the heat pump 100. The frequency of the compressor represents the rate of temperature rise and fall of the heat pump 100, and the temperature of the outlet of the first water supply pipe 110 directly reflects the actual working temperature of the subsequent radiant terminal 200 and double-cold-source integrated machine 400. After the heat pump 100 state detection device detects the actual working condition of the heat pump 100, it sends an electrical signal to the control device. The heat pump 100 state detection device and the control device are electrically connected. After the control device receives the electrical signal, it judges the actual working condition of the heat pump 100, and then sends a control signal to the boiler 300 operating device. The boiler 300 operating device and the control device are electrically connected. After the boiler 300 operating device receives the control signal, it starts to open or close the boiler 300.
[0052] More specifically, the heat pump 100 state detection device comprises: a compressor frequency detection part for detecting the frequency of the compressor when it is working; a first water supply pipe 110 outlet water temperature detection part for detecting the water temperature in the first water supply pipe 110; wherein the control device sends control signals to the boiler 300 operation device according to the control signals sent by the compressor frequency detection part and the first water supply pipe 110 outlet water temperature detection part to realize the control of the boiler 300 operation device. That is, the compressor frequency detection part sends an electrical signal to the control device after detecting the working frequency of the compressor, and the control device learns the actual working frequency of the compressor after receiving the electrical signal; the first water supply pipe 110 outlet water temperature detection part detects the actual temperature of the outlet of the first water supply pipe 110 and sends an electrical signal to the control device, and the control device learns the actual temperature of the outlet of the first water supply pipe 110 after receiving the electrical signal. Then the control device judges according to the actual working frequency of the compressor and the actual temperature of the outlet of the first water supply pipe 110, and sends control signals to the boiler 300 control device to realize the control of the opening and closing of the boiler 300.
[0053] More specifically, the boiler 300 operation device comprises: an ignition device for realizing the connection of the ignition circuit of the boiler 300 device according to the received control signal; an exhaust fan electromagnetic valve for realizing the opening or closing of the exhaust fan of the boiler 300 device according to the received control signal; a second water pump motor electromagnetic device for realizing the opening or closing of the second water pump according to the received control signal; an oxygen pipeline electromagnetic valve for realizing the control of the opening and closing degree of the oxygen pipeline according to the received control signal; wherein the control device sends control signals to the ignition device, exhaust fan electromagnetic valve, second water pump motor electromagnetic device and oxygen pipeline electromagnetic valve according to the control signals sent by the heat pump 100 state detection device.
[0054] Specifically, the ignition device realizes the connection of the ignition circuit of the boiler 300 device according to the electrical signal sent by the control device, and after the connection, the boiler 300 enters the running preparation state; the exhaust fan electromagnetic valve makes the exhaust fan start running after receiving the electrical signal sent by the control device, and the boiler 300 enters the running preparation state; the second water pump motor receives the start instruction, and the electromagnetic device (such as stator coil and rotor) in it will start working. The stator coil generates a magnetic field after being electrified, which interacts with the conductor in the rotor to generate a rotary torque, so that the second water pump motor starts to rotate. The oxygen pipeline electromagnetic valve realizes the opening and closing of the oxygen supply pipeline after receiving the control signal, and when the opening and closing angle increases, the running power of the boiler 300 increases, and when the opening and closing angle decreases, the running power of the boiler 300 decreases. When the ignition device, exhaust fan electromagnetic valve, second water pump motor electromagnetic device and oxygen pipeline electromagnetic valve all reach the open state, the boiler 300 starts to run.
[0055] In one specific embodiment, the control device comprises a main controller and a boiler 300 controller, which are electrically connected to each other to receive electrical signals. The energy-complementary radiant air conditioning device further comprises a refrigerant pressure sensor for detecting the pressure value of the refrigerant in the condenser; the control device sends control signals to the ignition device, the exhaust fan electromagnetic valve, the second water pump motor electromagnetic device, and the oxygen pipeline electromagnetic valve according to the control signal sent by the refrigerant pressure sensor.
[0056] Specifically, when the pressure value of the refrigerant in the condenser is lower than the set threshold value, the control device sends an electrical signal to the boiler 300 operating device to start the boiler 300. When the pressure value of the refrigerant in the condenser is greater than the set threshold value, the main controller sends a control signal to the boiler 300 controller, which sends a control signal to the boiler 300 operating device to start the boiler 300; when the pressure value of the refrigerant in the condenser is less than the set threshold value, the main controller sends a control signal to the boiler 300 controller, which maintains the t1 time and then sends a control signal to the boiler 300 operating device to close the boiler 300.
[0057] The control method of the energy-complementary radiant air conditioning device according to one embodiment of the present application comprises:
[0058] S100, the control device detects the temperature of the first water supply pipe 110 and the compressor frequency data according to the heat pump 100 state detection device; when the compressor frequency is opened to the maximum frequency and maintained for t1 time, and the temperature T1 in the first water supply pipe 110 is less than T-2℃, a control signal is sent to the boiler 300 operating device to start the boiler 300, wherein T is the temperature set by the user.
[0059] Specifically, in the heating mode, the control device monitors the temperature of the outlet of the first water supply pipe 110 in the heat pump 100 and the frequency of the compressor in real time; when the compressor frequency is opened to the maximum and maintained for 5 minutes, and the temperature T1 in the first water supply pipe 110 is less than the temperature set by the user minus 2℃, it is judged that the heat pump 100 has been difficult to meet the user's heating demand at this time, and the control device sends an electrical signal to the boiler 300 operating device, i.e. sends an electrical signal to start the ignition device, the exhaust fan electromagnetic valve, the second water pump motor electromagnetic device, and the oxygen pipeline electromagnetic valve, and the ignition device, the exhaust fan electromagnetic valve, the second water pump motor electromagnetic device, and the oxygen pipeline electromagnetic valve are all in the open state, and the boiler 300 starts to operate to heat the water in the first water supply pipe 110.
[0060] S200, the control device receives the refrigerant pressure sensor detects the refrigerant pressure value in the condenser, when the refrigerant pressure value in the condenser is greater than the set threshold, then the main controller sends a control signal to the boiler 300 controller, the boiler 300 controller sends the boiler 300 operating device to open the boiler 300 control signal; When the refrigerant pressure value in the condenser is less than the set threshold, then the main controller sends a control signal to the boiler 300 controller, the boiler 300 controller maintains t1 time to send the boiler 300 operating device to close the boiler 300 control signal.
[0061] Specifically, in the heating mode, the control device receives the defrosting signal, that is, the refrigerant pressure value in the condenser is greater than the set threshold, which indicates that the fin temperature of the condenser is too low and frost is generated. When frost is generated, the heat pump 100 needs to defrost the indoor temperature in reverse, resulting in the heat pump 100 always having to split a part of the power to frequently defrost, so that the water temperature in the water outlet pipe of the heat pump 100 cannot reach the user's set temperature. At this time, the main controller of the control device sends a control signal to the boiler 300 controller, and the boiler 300 controller sends an opening control signal to the boiler 300 operating device, that is, sends an opening electrical signal to the ignition device, the exhaust fan solenoid valve, the second water pump motor electromagnetic device and the oxygen pipeline electromagnetic valve. The ignition device, the exhaust fan solenoid valve, the second water pump motor electromagnetic device and the oxygen pipeline electromagnetic valve are all in an open state, and the boiler 300 starts to run to heat the water in the first water supply pipe 110.
[0062] When the control device receives the defrosting end signal, that is, when the refrigerant pressure value in the condenser is less than the set threshold, in order to reduce the water temperature fluctuation in the first water supply pipe 110, the main controller sends a control signal to the boiler 300 controller, and the boiler 300 controller maintains t1 time to send a control signal to the boiler 300 operating device to close the boiler 300. The t1 time here is 5 minutes.
[0063] When the boiler 300 is opened, the water temperature control logic is as follows:
[0064] The energy complementary radiant air conditioning device further comprises a second water supply pipe 310 outlet water temperature detection part for detecting the water temperature in the second water supply pipe 310. The second water supply pipe 310 outlet water temperature of the boiler 300 is set to dynamically change according to the set temperature of the heat pump 100 and the actual temperature difference of the heat pump 100 when the boiler 300 is opened.
[0065] Specifically:
[0066] When T-T1≥10℃, the control device sends a control signal to the oxygen pipeline solenoid valve to adjust the opening angle of the oxygen pipeline solenoid valve so that the water temperature in the second water supply pipe 310 detected by the outlet water temperature detection unit is equal to the water temperature in the first water supply pipe 110.
[0067] When 10℃>T-T1≥5℃, the control device sends a control signal to the oxygen pipeline solenoid valve to adjust the opening angle of the oxygen pipeline solenoid valve so that the water temperature in the second water supply pipe 310 detected by the outlet water temperature detection unit is equal to the water temperature in the first water supply pipe 110 minus 2℃.
[0068] When T-T1 < 5℃, the control device sends a control signal to the oxygen pipeline solenoid valve to adjust the opening angle of the oxygen pipeline solenoid valve so that the water temperature in the second water supply pipe 310 detected by the outlet water temperature detection unit is equal to the water temperature in the first water supply pipe 110 minus 4℃.
[0069] Where T is the temperature set by the user, and T1 is the actual temperature at the outlet of the first water supply pipe 110 in the heat pump 100.
[0070] The control method further includes:
[0071] When T1 is more than 4°C higher than the user-set temperature, and the boiler 300 has been running continuously for more than 5 minutes, the control device sends a control signal to the boiler 300 operating device to shut down the boiler 300.
