[0027] EMBODIMENT:

[0028] As Figures 1 to 4As shown, the embodiment provides a jet augmenting heat exchanger, which comprises a heat exchanger body 1, an augmenting device 2 and a liquid storage tank 3. The heat exchanger body 1 is composed of heat exchange pipes 11 arranged in a spiral stack. A first cavity is formed through the middle of the heat exchanger body 1. The augmenting device 2 is arranged in the first cavity of the heat exchanger body 1. The augmenting device 2 is composed of augmenting pipes 22 arranged in a spiral stack. A second space is formed through the middle of the augmenting device 2. The liquid storage tank 3 is arranged in the second space of the augmenting device 2. The heat exchange pipe 11 comprises an inner water pipe 110 and a first air pipe 111 wrapped outside the inner water pipe 110. The augmenting pipe 22 comprises a second air pipe 220 and a third air pipe 221 wrapped outside the second air pipe 220. The third air pipe 221 extends out of a segmented pipe 4 at the end. The segmented pipe 4 is connected with the liquid storage tank 3 and the second air pipe 220 respectively. The other end of the second air pipe 220 is connected with the first air pipe 111. The heat exchanger body 1, the augmenting device 2 and the liquid storage tank 3 can be integrated, which reduces the volume of the air conditioner, facilitates installation and reduces installation cost and material cost.

[0029] Further, the inner water pipe 110 is provided with a water inlet 112 and a water outlet 113 at both ends. The first air pipe 111 arranged outside the inner water pipe 110 is provided with a first air inlet 114 and a first air outlet 115 at both ends. The first air inlet 114 is arranged near the water outlet 113, and the first air outlet 115 is arranged near the water inlet 112. Water enters from the water inlet 112 and is discharged from the water outlet 113. Fluorine enters from the first air inlet 114, flows in the first air pipe 111 and is discharged from the first air outlet 115. The first air outlet 115 is connected with the second air pipe 220, flows in the second air pipe 220 and is discharged to the segmented pipe 4. One end of the segmented pipe 4 enters the liquid storage tank 3, and the other end enters the third air pipe 221 wrapped outside the second air pipe 220. After being discharged from the third air pipe 221, the fluorine enters the compressor.

[0030] Further, the water inlet 112 and the water outlet 113 are provided with a first temperature sensing device. The first temperature sensing device can detect the temperature of the water inlet 112 and the water outlet 113 and feed back the temperature information to the main circuit board.

[0031] Further, the water outlet 113 is provided with a water switch device. When the water switch device is closed, water is ensured in the inner water pipe 110 to prevent the inner water pipe 110 from being burnt by high temperature.

[0032] Further, the position where the segment pipe 4 is connected with the liquid storage tank 3 is provided with a throttling device, the second temperature sensing device is arranged at the two ends of the third air pipe 221, and the second temperature sensing device is electrically connected with the throttling device. The second temperature sensing device arranged at the two ends of the third air pipe 221 can sense the temperature of the fluorine entering and discharging from the third air pipe 221, and the size of the throttling device is controlled according to the temperature.

[0033] The enthalpy booster 2 can improve the efficiency of the compressor operation. On the basis of the normal operation of the evaporator, an enthalpy booster 2 is arranged after the heat exchanger and before the throttling device, a part of the medium-temperature high-pressure liquid is extracted, is changed into low-temperature low-pressure liquid through the throttling device, is changed into medium-temperature low-pressure gas through heat exchange in the heat exchanger, is sent back to the compressor in advance, the working temperature of the compressor is reduced, and thus the operation efficiency is improved.

[0034] As shown in Figure 5 The evaporator is further arranged and mainly responsible for heat exchange. The evaporator absorbs heat energy from air and evaporates the refrigerant (i.e. coolant) entering the evaporator to achieve the purpose of absorbing energy from air. The compressor can improve the pressure of the low-temperature low-pressure gas to high-temperature high-pressure gas. The low-temperature low-pressure refrigerant gas enters the compressor and is compressed into high-temperature high-pressure refrigerant gas to provide power for the heating cycle, so as to realize the heating cycle. The liquid storage tank 3 is connected with the evaporator.

[0035] Further, the compressor is connected with the third air pipe 221, the first air pipe 111 and the evaporator respectively to form a loop and finally enter the compressor.

[0036] Further, the four-way valve is arranged between the compressor and the heat exchanger body 1. The four-way valve can change the direction of the fluorine to change the cold and heat.

[0037] Further, the expansion valve is arranged between the liquid storage tank 3 and the evaporator. The expansion valve can change the throttling section or length in the heating system to control the flow of the refrigerant. The expansion valve throttles the medium-temperature high-pressure liquid refrigerant to become low-temperature low-pressure wet steam, and then the refrigerant enters the evaporator again to ensure the supply of hot water.

[0038] The jet enthalpy booster integrated heat exchanger can be applied to the air energy water heater. The low-temperature coolant in the compressor system continuously absorbs the heat in the air and then transfers the heat to the water. When the outdoor temperature is lower than 0 degree, the air energy water heater will stop working. Therefore, the jet enthalpy booster integrated heat exchanger can realize the internal operation through the enthalpy boosting technology in the case of lower than 0 degree, increase the heating capacity of the compressor in the cold weather, and thus normally operate. When the temperature sensed by the sensor is above 0 degree, the operation of the enthalpy booster is stopped, and the air energy water heater can normally operate through the heat exchanger.

[0039] The ejector heat-exchanger can be applied to air conditioners to change the function of cooling indoor air to heating indoor air, and in winter, heat can be extracted from outdoor low temperature air to heat indoor air, and in summer, the heat of indoor air can be removed and transferred to an outdoor air conditioner.

[0040] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
