[0018] Example:
[0019] like Figure 1As shown, the air-conditioning floor heating conversion device of the utility model comprises an insulated water tank 1, an air-conditioning indoor unit 2 and an air-conditioning outdoor unit 3. A heat exchange coil 4 is arranged in the insulated water tank 1, and the two ends of the heat exchange coil 4 are respectively connected with a first three-way pipe 5 and a second three-way pipe 6; the first three-way pipe 5 is connected to the first air-conditioning indoor unit interface 19 of the air-conditioning indoor unit 2 and the first air-conditioning outdoor unit interface 21 of the air-conditioning outdoor unit 3, and the second three-way pipe 6 is connected to the second air-conditioning indoor unit interface 20 of the air-conditioning indoor unit 2 and the second air-conditioning outdoor unit interface 22 of the air-conditioning outdoor unit 3; a first solenoid valve 7 is arranged at the end where the second three-way pipe 6 is connected to the heat exchange coil 4, and a second solenoid valve 8 is arranged at the end where the second three-way pipe 6 is connected to the second air-conditioning indoor unit interface 20; the insulated water tank 1 is provided with a water inlet 9 and a water outlet 10, a floor heating pipe 11 is connected between the water inlet 9 and the water outlet 10, and is matched with a corresponding circulation pump 12. The air-conditioning floor heating conversion device of the present invention cooperates with an insulated water tank 1, an air-conditioning indoor unit 2, an air-conditioning outdoor unit 3, a heat exchange coil 4, a first three-way pipe 5, a second three-way pipe 6, a first air-conditioning indoor unit interface 19, a first air-conditioning outdoor unit interface 21, a second air-conditioning indoor unit interface 20, a second air-conditioning outdoor unit interface 22, a first solenoid valve 7, a second solenoid valve 8, a floor heating pipe 11 and a circulating pump 12. When the floor heating pipe 11 is used, the first solenoid valve 7 is opened and the second solenoid valve 8 is closed, so that the high-temperature and high-pressure gas of the air-conditioning outdoor unit 3 enters the heat exchange coil 4 from the first three-way pipe 5 to heat the water in the insulated water tank 1, and the water in the insulated water tank 1 enters the floor heating pipe 11 for heating. When the floor heating pipe 11 is not used, the first solenoid valve 7 is closed and the second solenoid valve 8 is opened, so that the high-temperature and high-pressure gas does not pass through the heat exchange coil 4 but directly enters the air-conditioning indoor unit 2. The device can be used for heating by floor heating or by air conditioning, and the switching is flexible and convenient. It is a comfortable and economical heating method. It should be noted that the diameter and number of coils of the heat exchange coil 4 in the insulated water tank 1 are determined according to the power of the air conditioner. By controlling the solenoid valve switch, the air conditioner and the floor heating can be easily switched, and when the floor heating is not used, all functions of the air conditioner are not affected.
[0020] Preferably, the air conditioner indoor unit 2 is provided with a first fin air heat exchanger 13, and the two ends of the first fin air heat exchanger 13 are respectively connected to the first air conditioner indoor unit interface 19 and the second air conditioner indoor unit interface 20. It should be noted that the air conditioner indoor unit 2 is also provided with other components such as a fan, which is a prior art and will not be described again.
[0021] Preferably, the air conditioner outdoor unit 3 is provided with a throttle 14, a second fin air heat exchanger 15, a four-way valve 16 and an air compressor 17 connected in sequence, the four-way valve 16 is connected to the first air conditioner outdoor unit interface 21, and the throttle 14 is connected to the second air conditioner outdoor unit interface 22. It should be noted that the air conditioner outdoor unit 3 is also provided with other components such as a fan, which is a prior art and will not be described again.
[0022] Preferably, the throttle 14 is a capillary tube or an electronic expansion valve.
[0023] Preferably, the heat exchange coil 4 and the floor heating pipe 11 are both made of plastic pipes.
[0024] Preferably, the wall of the insulated water tank 1 is made of hollow stainless steel, and a foam insulation board is embedded in the hollow part.
[0025] As a preferred embodiment, the air conditioner is turned on in the heating mode, and the four-way valve of the air conditioner outdoor unit 3 is connected. When using floor heat for heating, the first solenoid valve 7 is opened and the second solenoid valve 8 is closed. The circulation pump 12 is turned on to circulate water in the floor heating pipe 11 and the insulation water tank 1. The high-temperature and high-pressure refrigerant gas discharged by the compressor 17 passes through the corresponding port of the four-way valve, and the first air conditioner outdoor unit interface 21 is connected to the heat exchange coil 4 through the first three-way pipe 5. Due to the condensation of the circulating water, the refrigerant is condensed from gas to liquid (exothermic), and then passes through the first solenoid valve 7 (the second three-way pipe 6 to the throttle 14 (capillary or electronic expansion valve) and is decompressed. After entering the second fin air heat exchanger 15, the refrigerant is converted from liquid to gas (absorbent), and enters the suction port of the compressor 17 through the corresponding port of the four-way valve to be pressurized, and then discharged through the exhaust port. The continuous cycle realizes the heating of the circulating water for floor heating. When the floor heating is not used, the first solenoid valve 7 and the circulation pump 12 can be closed, and the second solenoid valve 8 can be opened at the same time to restore all the functions of the air conditioner. Function. When the air conditioner is turned on in heating mode, the gaseous refrigerant is pressurized by the compressor 17, and then flows from the exhaust port of the compressor 17 to the corresponding port of the four-way valve, and is connected to the first fin heat exchanger 13 through the first three-way pipe 5. The refrigerant is condensed from gas to liquid, passes through the second solenoid valve 8, and then to the throttle 14 (capillary tube or electronic expansion valve). After the pressure is reduced, the liquid refrigerant enters the second fin heat exchanger 15 to evaporate, passes through the corresponding port of the four-way valve 16 to the air inlet port of the compressor 17, and is discharged through the exhaust port of the compressor after being pressurized by the compressor 17. This cycle is used to realize the heating process of the indoor unit of the air conditioner.
[0026] As can be seen from the figure, by opening and closing the first solenoid valve 7 and the second solenoid valve 8, the original passage to the indoor unit is cut off, and the path of the refrigerant can be changed. The first solenoid valve 7 is opened, and the second solenoid valve 8 is closed, and the refrigerant passes through the heat exchange coil 4 to heat the circulating water. The first solenoid valve 7 is closed, and the second solenoid valve 8 is opened, and the original passage of the air-conditioning refrigerant is restored, and the refrigerant passes through the air-conditioning indoor unit 2 to heat the indoor air. It can be seen from this that when floor heating is not used, all functions of the air conditioner are not affected. It can also be said that the functions of floor heating and radiator heating are added to the original air conditioner.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
