Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning energy saving, and in particular relates to a dehumidification air-conditioning system with heat pipe humidity regulation. Background Art

[0002] like Figure 1 As shown, the working principle of air conditioning during cooling is demonstrated. The air conditioning compressor 100 is used to vaporize the refrigerant near the air conditioning evaporator 300 to reduce the temperature of the air conditioning evaporator 300. The vaporized refrigerant is liquefied at the air conditioning condenser 200 and flows to the air conditioning evaporator 300 again. When the air flows through the air conditioning evaporator 300 under the action of the fan 400, the temperature will be reduced by the air conditioning evaporator 300, so that cold air is blown out. However, due to the low temperature of the air conditioning evaporator 300, the moisture in the air will reach the dew point condensation when passing through the air conditioning evaporator 300, and condensed water will be formed on the surface of the air conditioning evaporator 300. The uncondensed moisture in the air is also near the dew point, and the overall humidity of the air is high. In some scenarios, the air conditioner also needs to heat the dehumidified air through an additional electric heating section 500 to output air with appropriate humidity.

[0003] After the existing air conditioning system cools and dehumidifies the air, it needs to use the electric heating section 500 to heat the air to obtain air with a relatively suitable humidity. This will cause the electric heating section to consume a lot of electricity. At the same time, there is high-temperature air at the air inlet, and the heat of the high-temperature air is not reasonably recovered and utilized. Utility Model Content

[0004] The utility model aims to solve the problem that the existing air-conditioning system needs to use an electric heating section to heat the air after cooling and dehumidifying the air in order to obtain air with a relatively suitable humidity, which will cause the electric heating section to consume a large amount of electric energy, and at the same time there is high-temperature air at the air inlet, and the heat of the high-temperature air is not reasonably recovered and utilized. Therefore, a dehumidifying air-conditioning system with heat pipe humidity control is provided, which can transfer heat through two sections of heat pipes in the air conditioner, and the transferred heat is reasonably applied inside the air conditioner, which can reduce the working power of the compressor and save the energy consumption of the air conditioning system for heating the dehumidified air.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model provides a dehumidification air-conditioning system with heat pipe humidity control, including a heat pipe, an evaporator, a condenser, a fan, a filter, a protective net, a compressor and an expansion valve. From the air inlet end to the air outlet end of the air-conditioning system, a filter, a cooling pipe, an evaporator, a heating pipe, a fan and a protective net are arranged in sequence; the heat pipe includes a cooling pipe, a heating pipe, a first transition connection and a second transition connection, and the first transition connection and the second transition connection are respectively arranged between the cooling pipe and the heating pipe. The cooling pipe and the heating pipe have circulating media for absorbing and releasing heat respectively, and the cooling pipe circulates the air internally after cooling the air. The medium temperature rises and becomes vapor, and enters the heating pipe through the first transition connection; after the heating pipe heats the air, the temperature of the internal circulating medium decreases and becomes liquid, and enters the cooling pipe through the second transition connection; the surface of the evaporator is provided with a number of vertically downward fins, and the middle of the evaporator is provided with a number of air holes; after the air passes through the filter and the cooling pipe from the air inlet end of the air-conditioning system, it first contacts the fins on the surface of the evaporator, and then passes through the air holes, thereby completing the convection of air and the evaporator, and then reaches the air outlet end of the air-conditioning system through the heating pipe, the fan and the protective net; the expansion valve, the compressor and the condenser are connected in sequence below the evaporator.

[0006] Furthermore, the cooling pipe, the first transition connection, and the heating pipe constitute an integral U-shaped heat pipe, the cooling pipe is the evaporation section of the heat pipe arranged at the front side of the evaporator, the heating pipe is the condensation section of the heat pipe arranged at the rear side of the evaporator, the first transition connection is the transition section between the evaporation section and the condensation section, and the vapor circulation medium inside the evaporation section enters the condensation section through the transition section. The second transition connection is a capillary structure layer evenly distributed on the inner wall of the heat pipe, and a number of fine holes or grooves are formed inside the capillary structure layer, and the liquid circulation medium inside the heating pipe enters the cooling pipe through the capillary structure layer.

[0007] Furthermore, the first transition connection is a first transition pipe connecting the cooling pipe and the heating pipe, and the vapor circulating medium inside the cooling pipe enters the heating pipe through the first transition pipe; the second transition connection is a second transition pipe, and the second transition pipe is provided with a circulation pump for pumping the liquid circulating medium in the cooling pipe into the heating pipe.

[0008] Furthermore, it also includes a collecting tank, a water pump, a condensed water discharge pipe and an atomizer. The collecting tank is arranged below the evaporator, the collecting tank is connected to the water pump through the condensed water discharge pipe, the water pump is connected to the atomizer, and the atomizer is directly opposite to the condenser.

[0009] The utility model arranges heat pipes on both sides of the air conditioner evaporator, pre-cools the air entering the air conditioner through the evaporation end of the heat pipe, thereby preventing the evaporator temperature from rising too fast, and then increases the temperature of the air discharged from the air conditioner through the condensation section of the heat pipe, so that the humidity of the air discharged from the air conditioner is reduced and the temperature is comfortable. The dehumidification air conditioning system with heat pipe humidity adjustment can save the traditional electric heating section, and can still increase the temperature of the dehumidified air without an external heat source, so as to obtain air with suitable humidity, reduce the energy consumption of heating the air, and recover the energy in the air through the heat pipe. The heat recovery efficiency of the heat pipe is between 30% and 60%, which can well reduce the energy consumption of the air conditioning system. Compared with the traditional air conditioner, the humidity of the air discharged by the technical solution can be maintained between 50% and 75%, which is more comfortable and dry than the wet air with a humidity of more than 90% directly discharged without the heat pipe. The use of heat pipes to pre-cool the air can prevent the temperature of the evaporator from rising too fast, can reduce the power of the compressor, make the compressor work smoothly, and increase the service life of the compressor. In addition, the heat pipe uses the heat of the air to increase the temperature of the air after condensation, and the temperature of the two sections of the heat pipe in contact with the air is effectively recovered and reasonably used.

[0017] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the dehumidification air conditioning system with heat pipe humidity control of the utility model in conjunction with the accompanying drawings.

[0018] Reference Figure 2 and Figure 3 The dehumidification air conditioning system with heat pipe humidity control includes a heat pipe 10, an evaporator 20, a condenser 30, a fan 50, a filter 60, a protective net 70, a compressor 80 and an expansion valve 90. The filter 60, the cooling pipe, the evaporator 20, the heating pipe, the fan 50 and the protective net 70 are arranged in sequence from the air inlet end to the air outlet end of the air conditioning system. The heat pipe includes a cooling pipe, a heating pipe, a first transition connection and a second transition connection. The first transition connection and the second transition connection are respectively arranged between the cooling pipe and the heating pipe. There are circulating media for absorbing and releasing heat in the cooling pipe and the heating pipe respectively. After the cooling pipe cools the air, the temperature of the internal circulating medium increases and becomes a vapor state, and enters the heating pipe through the first transition connection; after the heating pipe heats the air, the temperature of the internal circulating medium decreases and becomes a liquid state, and enters the cooling pipe through the second transition connection; the surface of the evaporator 20 is provided with a plurality of vertically downward fins, and the middle of the evaporator 20 is provided with a plurality of air holes; after the air passes through the filter 60 and the cooling pipe from the air inlet end of the air conditioning system, the air first contacts the fins on the surface of the evaporator 20, and then passes through the air holes, thereby completing the convection between the air and the evaporator 20, and then reaches the air outlet end of the air conditioning system through the heating pipe, the fan 50 and the protective net 70; the expansion valve 90, the compressor 80 and the condenser 30 are connected in sequence below the evaporator 20.

[0019] There are two types of heat pipe 10, see Figure 2 and Figure 3 , which are introduced below.

[0020] Reference Figure 2 The cooling tube, the heating tube, and the first transition connection are an integral U-shaped heat pipe 10. The cooling tube is the evaporation section 11 of the heat pipe 10 arranged at the front side of the evaporator 20, and the heating tube is the condensation section 12 arranged at the rear side of the evaporator 20. The first transition connection is the transition section 13 between the evaporation section 11 and the condensation section 12. The vapor circulation medium in the evaporation section 11 enters the condensation section 12 through the transition section 13. The second transition connection is the capillary structure layer 14 evenly distributed on the inner wall of the U-shaped tube. A number of fine holes or grooves are formed inside the capillary structure layer 14. The liquid circulation medium in the condensation section 12 can overcome the influence of gravity through the capillary structure layer 14 and flow upward through the transition section 13 to enter the evaporation section 11.

[0021] The air is sucked from right to left by the fan 50. The air first contacts the filter 60 at the air inlet end, and then contacts the evaporation section 11. The temperature of the evaporation section 11 will rise, and the circulating medium in the evaporation section 11 can convect to the condensation section 12 through the transition section 13, while the temperature of the air will drop, so that the air is pre-cooled, and the pre-cooled air contacts the evaporator 20. The surface of the evaporator 20 is provided with a plurality of fins pointing vertically downward, and the middle of the evaporator 20 is provided with a plurality of air holes. The water vapor in the air is removed by the evaporator 20. The air first contacts the fins on the surface of the evaporator 20, and then passes through the air holes, thereby completing the convection between the air and the evaporator 20. The evaporator 20 can reduce the humidity of the air. After the air is dehumidified, the air is in a low temperature and low humidity state, and the temperature of the air rises after contacting the condensation section 12. The temperature inside the condensation section 12 decreases, the circulating medium condenses into liquid, and the circulating medium in liquid returns to the right evaporation section 11 through the capillary action of the capillary structure layer 14, realizing energy recovery. A protective net 70 is installed at the air outlet of the air conditioner.

[0022] The expansion valve 90, the compressor 80 and the condenser 30 are connected in sequence below the evaporator 20. The evaporator 20 is filled with a cooling medium. The cold source in the evaporator 20 circulates and refrigerates under the action of the compressor 80, the condenser 30, the expansion valve 90 and the internal cooling medium.

[0023] In addition, since the condenser 30 generates a large amount of heat when working, the condensed water falling from the evaporator 20 can also be reasonably utilized. A collecting tank 41 is set below the evaporator 20 in the air conditioner, and the condensed water sliding down from the evaporator 20 is collected by the collecting tank 41. The collecting tank is connected to a pump through a condensed water external discharge pipe, and the pump is connected to an atomizer. The condensed water is guided to an atomizer 44 located outside the air conditioner through a pump 42 and a condensed water external discharge pipe 43, wherein the atomizer 44 is directly opposite to the condenser 30, and the condensed water is sprayed on the condenser 30 to accelerate the cooling of the condenser 30.

[0024] Reference Figure 3, another form of heat pipe, the heat pipe 10 is replaced by two sections of cooling pipe 111 and heating pipe 121, both of which are filled with heat-conducting medium. The cooling pipe 111 and the heating pipe 121 are connected by a first transition connection and a second transition connection. The first transition connection is a first transition pipe 131 connecting the cooling pipe and the heating pipe. The vapor circulating medium in the cooling pipe 111 enters the heating pipe 121 through the first transition pipe 131. The second transition connection is a second transition pipe 132, and the second transition pipe 132 is provided with a circulation pump 133 for pumping the liquid circulating medium in the heating pipe 121 into the cooling pipe 111; the cooling pipe 111 is located on the air inlet side of the evaporator 20, and can pre-cool the air. The heating pipe 121 is located on the air outlet side of the evaporator 20, and can heat the dehumidified air. The cooling tube 111, the heating tube 121, the first transition tube 131 and the second transition tube 132 can replace the heat pipe 10 to realize heat circulation, and the circulation pump 133 can control the flow rate of the medium inside the cooling tube and the heating tube to ensure rapid circulation of heat.
