Technical Field

[0001] This invention relates to the field of air conditioning systems, and more particularly to a multi-functional air conditioning system. Background Technology

[0002] In current household life, air conditioning systems are used to lower indoor temperatures in summer and raise them in winter. Humidifiers are used to regulate humidity when the air is dry, and dehumidifiers are used to remove moisture when the air is damp. However, most modern homes are quite cramped and lack dedicated spaces for drying clothes. The problems with these methods include:

[0003] 1. The integration level is low, requiring dedicated air conditioning systems, heaters, dehumidifiers, etc. to achieve the above functions, resulting in higher costs;

[0004] 2. Existing air conditioning systems blow out hot air and discharge condensate when cooling, which affects the external environment and the condensate cannot be reused. Summary of the Invention

[0005] To overcome at least one of the defects described in the prior art, this invention provides a multifunctional air conditioning system. Through the cooperation of a compressor, economizer, condenser, intermediate heat exchanger, evaporator, and air purification filter, an air conditioning system integrating cooling, heating, dehumidification, humidification, clothes drying, and odor removal is achieved. This system boasts a high degree of integration, saves costs, and utilizes a fan in conjunction with the first condenser to discharge air and moisture at temperatures not exceeding ambient temperature, thus addressing user pain points in practical applications.

[0006] The technical solution adopted by this invention to solve its problem is:

[0007] A multi-functional air conditioning system includes a compressor, an evaporator, and an intermediate heat exchanger, and further includes: a condenser, comprising a first condenser and a second condenser; an air inlet, wherein an air purification filter for purifying and deodorizing is provided at the air inlet; an economizer, wherein two economizer channels are respectively connected between the compressor and the first condenser and between the compressor and the intermediate heat exchanger; a fan for blowing air and an up-and-down swing damper, wherein the up-and-down swing damper adjusts the air outlet direction of the fan up and down.

[0008] By adopting the above solution, the exhaust temperature can be reduced by setting an economizer, thereby achieving better cooling and heating effects. By setting an air purification filter, dust and impurities in the air can be effectively filtered to achieve deodorization. This realizes an air conditioning system that integrates cooling, heating, dehumidification, humidification, clothes drying, and deodorization, with a high degree of integration and cost savings.

[0009] Furthermore, the compressor is provided with an inlet port and an outlet port; the first condenser is provided with a first port and a second port, the second condenser is provided with a third port and a fourth port, the intermediate heat exchanger is provided with a fifth port, a sixth port, a seventh port, and an eighth port, and the evaporator is provided with a ninth port and a tenth port; wherein, the first port of the first condenser is connected to the outlet port of the compressor via a first high-pressure pipe; the third port of the second condenser is connected to the outlet port of the compressor via a second high-pressure pipe; the fifth port of the intermediate heat exchanger is connected to the second port of the first condenser via a first capillary tube; the fifth port of the intermediate heat exchanger is connected to the fourth port of the second condenser via a second capillary tube; the sixth port of the intermediate heat exchanger is connected to the inlet port of the compressor via a return pipe; the outlet port of the compressor is connected to the fifth port of the intermediate heat exchanger via a third high-pressure pipe; the ninth port of the evaporator is connected to the seventh port of the intermediate heat exchanger via a first connecting pipe, and the tenth port of the evaporator is connected to the eighth port of the intermediate heat exchanger via a second connecting pipe.

[0010] By adopting the above scheme and designing the above ports, the compressor is connected to the first condenser, the second condenser, and the intermediate heat exchanger, and the intermediate heat exchanger is connected to the first condenser, the second condenser, and the evaporator, which facilitates the realization of functions such as cooling, heating, and dehumidification.

[0011] Furthermore, it also includes a condensate collection box, the top of which has an opening, for receiving and containing condensate generated from the first condenser and the second condenser.

[0013] Furthermore, an atomizer is provided inside the condensate collection box, which is used to atomize the water in the condensate collection box; and the economizer is also located inside the condensate collection box.

[0014] By adopting the above solution, the water in the condensate collection box can be atomized by turning on the atomizer, and then sucked out by the fan to achieve the humidification function.

[0015] Furthermore, it also includes an evaporation water collection box, the top of which has an open opening. The evaporation water collection box is used to receive and contain condensate generated from the evaporator.

[0017] Furthermore, it also includes an absorbent cotton cloth, the end of which contacts the overflow trough, and the absorbent cotton cloth is at least partially located in the condensate collection box.

[0018] By adopting the above solution, the water in the evaporation water collection box will flow into the water-absorbing cotton cloth through the overflow tank, and then slowly drip into the condensate water collection box through the water-absorbing cotton cloth, effectively preventing the condensate water from overflowing. When the fan is working, it will draw the hot and humid air into the condenser to cool the condenser, so that the exhaust air is no longer hot air.

[0019] Furthermore, a dryer filter and a first throttling device are sequentially installed on the first capillary tube flowing from the first condenser into the intermediate heat exchanger; a first solenoid valve is installed on the third high-pressure pipe flowing from the compressor into the heat exchanger; a second solenoid valve is installed on the second high-pressure pipe flowing from the compressor into the second condenser; a second throttling device is installed on the second capillary tube flowing from the second condenser into the heat exchanger; and a water pump is installed on the first connecting pipe flowing from the heat exchanger into the evaporator.

[0020] By adopting the above scheme, the dryer filter can filter out impurities in the pipes, such as metal shavings, various oxides, and dust, preventing blockages and clogging of components; the first and second throttling devices can change the pressure to achieve throttling and pressure reduction; the first and second solenoid valves can control the refrigerant flow rate, thereby controlling the air conditioning cooling effect; and the water pump facilitates the transfer of refrigerant from the intermediate heat exchanger to the evaporator.

[0021] Furthermore, the first high-pressure tube, the second high-pressure tube, and the third high-pressure tube at least partially overlap, and the first capillary tube and the third capillary tube at least partially overlap.

[0022] By adopting the above solution, the amount of pipeline used can be reduced, thus lowering costs.

[0023] Furthermore, the first throttling device is a throttling orifice plate, and / or the second throttling device is a throttling orifice plate.

[0024] By adopting the above solution, the cost-saving effect is good.

[0025] Furthermore, a refrigerant is provided inside the intermediate heat exchanger.

[0026] By adopting the above scheme, cooling is achieved through a refrigerant.

[0027] In summary, the multi-functional air conditioning system provided by this invention has the following technical effects:

[0028] 1. Through the coordinated operation of the compressor, first condenser, second condenser, evaporator, intermediate heat exchanger, atomizer, air purification filter, and upper and lower swing dampers, it achieves cooling, heating, dehumidification, humidification, clothes drying, and deodorization functions. It adopts an integrated design, which has more functions and saves more costs.

[0029] 2. The design of the absorbent cotton cloth allows the condensate produced by the evaporator and condenser to drip into the condensate water absorption box. The fan then draws air into the condenser, achieving the effect of cooling the condenser. Moreover, the exhaust air is at a temperature no higher than the ambient temperature, which solves the problem of exhausting hot air in the existing technology. Attached Figure Description

[0042] In this embodiment, a refrigerant is provided in the intermediate heat exchanger 3 to achieve cooling operation. The refrigerant includes, but is not limited to, ethylene glycol.

Through the design of these ports, the compressor 1 is connected to the first condenser 4, the second condenser 5, and the intermediate heat exchanger 3, and the intermediate heat exchanger 3 is connected to the first condenser 4, the second condenser 5, and the evaporator 2, facilitating the realization of functions such as cooling, heating, and dehumidification.

[0044] In this embodiment, one of the economizer channels is connected in parallel with the first high-pressure pipe 101, and the other economizer channel is connected in parallel with the return pipe 105.

[0045] A dryer filter 113 and a first throttling device 114 are sequentially arranged on the first capillary tube 103 in the direction of the first condenser 4 flowing into the intermediate heat exchanger 3; a first solenoid valve 115 is arranged on the third high-pressure pipe 100 in the direction of the compressor 1 flowing into the heat exchanger; a second solenoid valve 116 is arranged on the second high-pressure pipe 102 in the direction of the compressor 1 flowing into the second condenser 5; a second throttling device 117 is arranged on the second capillary tube 104 in the direction of the second condenser 5 flowing into the heat exchanger; and a water pump 118 is arranged on the first connecting pipe 106 in the direction of the heat exchanger flowing into the evaporator 2. The dryer filter 113 removes impurities from the pipes, such as metal shavings, various oxides, and dust, preventing blockages and clogging of components. The first throttling device 114 and the second throttling device 117 can adjust the pressure to achieve throttling and pressure reduction. The first solenoid valve 115 and the second solenoid valve 116 control the refrigerant flow rate and enable remote centralized control via signal, facilitating switching and controlling the air conditioner's cooling effect. The water pump 118 facilitates the transfer of refrigerant from the intermediate heat exchanger 3 to the evaporator 2. It should be noted that in this embodiment, the first throttling device 114 and the second throttling device 117 can be orifice plates for better throttling effect. In this embodiment, the first high-pressure pipe 101, the second high-pressure pipe 102, and the third high-pressure pipe 100 at least partially overlap, and the first capillary tube 103 and the third capillary tube at least partially overlap. This saves on pipe usage and reduces costs.

[0046] In this embodiment, a condensate collection box 108 is also included. The top of the condensate collection box 108 is open. The condensate collection box 108 is used to receive and contain the condensate generated from the first condenser 4 and the second condenser 5. The condensate collection box 108 receives the water generated by the condensation of the first condenser 4 and the second condenser 5, facilitating subsequent operations. An atomizer 109 is provided inside the condensate collection box. The atomizer 109 is used to atomize the water in the condensate collection box 108. By turning on the atomizer 109, the water in the condensate collection box 108 can be atomized and then drawn out by the fan 10, realizing the humidification function. Specifically, the economizer 8 can also be installed inside the condensate collection box 108.

[0047] In this embodiment, an evaporation water collection box 110 is also included. The top of the evaporation water collection box 110 is open. The evaporation water collection box 110 is used to receive and contain the condensate generated from the evaporator 2. The bottom of the evaporation water collection box 110 is inclined. An overflow trough 111 is provided at the bottom of the evaporation water collection box 110. The evaporation water collection box 110 receives the water condensed by the evaporator 2 and flows out through the overflow tank 111 for subsequent operations; it also includes an absorbent cotton cloth 112, the end of which contacts the overflow tank 111, and the absorbent cotton cloth 112 is at least partially located in the condensation water collection box 108; when the absorbent cotton cloth 112 contacts the overflow tank 111, the water in the evaporation water collection box 110 will flow into the absorbent cotton cloth 112 through the overflow tank 111, and then slowly drip into the condensation water collection box through the absorbent cotton cloth 112, effectively preventing the condensation water from overflowing. When the fan 10 is working, it will draw the hot and humid air into the condenser to cool the condenser, so that the exhaust air is no longer hot air.

[0048] During heat exchange, the surface of the evaporator 2 condenses into water droplets, which fall into the evaporation water collection box 110. The water in the evaporation water collection box 110 drips through the overflow trough 111 onto the absorbent cotton cloth 112, and then slowly drips from the absorbent cotton cloth 112 onto the condensation water collection box 108. When the fan 10 is working, it draws the hot and humid air onto the condenser to cool it down, and the exhaust air is at a temperature no higher than the ambient temperature.

[0049] See Figure 2 The cooling mode works as follows: the exhaust from compressor 1 first passes through economizer 8 to the first condenser 4 to release heat, then passes through dryer filter 113 and first throttling device 114 to enter intermediate heat exchanger 3, and then returns to compressor 1 through economizer 8, thus achieving the goal of not producing air with a temperature higher than the ambient temperature during condensation; after the refrigerant in intermediate heat exchanger 3 is cooled, it is transported to evaporator 2 through water pump 118, and then returns from evaporator 2 to intermediate heat exchanger 3. At this time, it is in cooling mode, and the fan 10 blows the air out horizontally from the up-and-down swing damper 9 to achieve the cooling effect, and no air with a temperature higher than the ambient temperature is discharged during cooling.

[0050] See Figure 3 The heating mode works as follows: The exhaust gas from the compressor 1 first passes through the first high-pressure pipe 101 and enters the intermediate heat exchanger 3 through the solenoid valve. The hot gas is discharged and then returns to the compressor 1 through the return pipe and the economizer 8. At this time, the refrigerant in the intermediate heat exchanger 3 is heated and goes to the evaporator 2 through the water pump 118, and then returns to the intermediate heat exchanger 3. This is the heating mode. The fan 10 blows the air out horizontally from the up-and-down swing damper 9 to achieve the heating effect.

[0051] See Figure 4The dehumidification mode works as follows: The exhaust from the compressor 1 first passes through the second solenoid valve 116 to the second condenser 5, and then returns to the intermediate heat exchanger 3 through the second throttling device 117. At this time, the refrigerant in the intermediate heat exchanger 3 is cooled. After cooling, it passes through the economizer 8 and returns to the compressor 1. After cooling, the refrigerant in the intermediate heat exchanger 3 is transported to the evaporator 2 by the water pump 118, and then returns to the intermediate heat exchanger 3. At this time, it is the dehumidification mode. The fan 10 blows the air out horizontally from the up-and-down swing damper 9 to achieve the dehumidification effect.

[0052] See Figure 5 The drying mode works by blowing air upwards from the swinging damper 9 through the fan 10, based on the dehumidification mode, to achieve the drying effect.

[0053] See Figure 6 The humidification mode works as follows: the compressor 1 stops working, the atomizer 109 is turned on, the atomizer 109 can atomize the water in the condensate collection box 108, and after atomization, it is drawn out by the fan 10 to achieve the humidification effect.

[0054] In summary, the multi-functional air conditioning system provided by this invention has the following technical effects:

[0055] 1. Through the cooperation of compressor 1, first condenser 4, second condenser 5, evaporator 2, intermediate heat exchanger 3, atomizer 109, air purification filter 7, and upper and lower swing damper 9, the functions of cooling, heating, dehumidification, humidification, clothes drying, and deodorization are realized. It adopts an integrated design, with more functions and greater cost savings.

[0056] 2. The design of the absorbent cotton cloth 112 allows the condensate produced by the evaporator 2 and the condenser to drip into the condensate suction box. The fan 10 then draws air into the condenser, achieving the effect of cooling the condenser. Moreover, the exhaust air is at a temperature no higher than the ambient temperature, which solves the problem of exhausting hot air in the prior art.

[0057] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
