Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat pump type solution dehumidification unit, in particular to a fresh air heat exchange and humidity control integrated mechanism and a heat pump type solution fresh air unit. BACKGROUND

[0002] The heat pump type solution dehumidification unit is an advanced environmental fresh air control system integrating high-efficiency dehumidification, humidification, air purification and energy saving, which is widely used in scenes with strict requirements on humidity, cleanliness and energy saving, and is a key technology to promote building energy saving and healthy environment upgrading.

[0003] The core of the heat pump type solution dehumidification unit is to absorb water in the air by salt solution, combine with heat pump technology, use condensation heat to regenerate solution, realize self-circulation and efficient use of energy. In the conventional heat pump type solution fresh air unit on the market, the heat exchange and humidity control module is another core mechanism in addition to the heat pump driving system. The heat exchange and humidity control module of the present application is realized by the contact between the solution and the air in the process of the air cooling and humidity control. In this process, the solution is sprayed from the top of the filler tower to the lower grid filler, from top to bottom, and finally falls into the recovery tank at the bottom of the filler tower. During the whole process, the temperature of the low-temperature or high-temperature salt solution gradually changes, resulting in a significant decrease in the effect of the salt solution absorbing water in the air or releasing water in the solution due to the temperature change caused by the heat exchange between the air and the solution. Moreover, the humidity control process is achieved by adjusting the total spray flow of the salt solution and the air speed, which lacks flexibility in humidity control, and the effect of fresh air cooling or heating is also relatively affected.

[0004] Therefore, the present application provides a fresh air heat exchange and humidity control integrated mechanism and a heat pump type solution fresh air unit. SUMMARY

[0005] The purpose of the present application is to provide a fresh air heat exchange and humidity control integrated mechanism and a heat pump type solution fresh air unit to solve the above-mentioned problems existing in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0007] The fresh air heat exchange and humidity control integrated mechanism provided by the present application comprises an outer shell and a heat exchange and humidity control tower installed inside the outer shell for heat exchange and humidity control of air. The heat exchange and humidity control tower is composed of a plurality of groups of heat exchange and humidity control components stacked up and down, and a gap is left between each group of heat exchange and humidity control components to facilitate the air to mix in the gap and then pass through the upper heat exchange and humidity control component. This not only improves the uniformity of air humidity control, but also improves the air heat exchange efficiency.

[0008] Further, the heat exchange and humidity control assembly comprises a heat exchange assembly and a mounting frame fixed to four corners of the heat exchange assembly, and the heat exchange and humidity control assembly is mainly installed in the shell through the mounting frame fixed to the four corners and cooperated with bolts, wherein the top of the heat exchange assembly is provided with a plurality of groups of solution spraying units arranged side by side, and the solution spraying unit comprises a flat baffle and a liquid distribution groove integrally formed at the bottom of the baffle, and a plurality of spraying holes are uniformly arranged on both sides of the liquid distribution groove from left to right, so that the salt solution is uniformly sprayed out of the liquid distribution groove, which is convenient for subsequent air humidity control.

[0009] Further, the heat exchange assembly is further provided with a refrigerant delivery branch pipe and a refrigerant recovery branch pipe at two ends, respectively, and one end of each of the plurality of groups of solution spraying units is connected to the solution delivery branch pipe, and a first electromagnetic valve is arranged on the solution delivery branch pipe to adjust the spraying flow of the salt solution into the heat exchange assembly, wherein specifically, the solution delivery branch pipe, the refrigerant delivery branch pipe and the refrigerant recovery branch pipe of each of the plurality of heat exchange and humidity control assemblies constituting the heat exchange and humidity control tower extend to the outside of the shell, and each of the solution delivery branch pipe, the refrigerant delivery branch pipe and the refrigerant recovery branch pipe in the heat exchange and humidity control tower is connected in series by a salt solution delivery main pipe, a refrigerant delivery main pipe and a refrigerant recovery main pipe, respectively, and a booster magnetic pump is arranged at the end of the salt solution delivery main pipe, and a refrigerant booster pump is arranged at the end of the refrigerant delivery main pipe, wherein the booster magnetic pump is used to assist the pressurization of the salt solution treated by the heat pump system and then deliver the salt solution into the heat exchange and humidity control tower, so that each of the solution spraying units in each of the heat exchange and humidity control assemblies has sufficient pressure to uniformly spray the salt solution, and the refrigerant booster pump is used to assist the pressurization of the refrigerant entering the heat exchange and humidity control tower, so that the refrigerant can smoothly pass through each of the heat exchange assemblies.

[0010] Further, in order to cooperate with the refrigerant to complete the air heat exchange effect, the heat exchange assembly comprises a heat conduction base plate and an upper cover body and a lower cover body assembled on the upper and lower surfaces of the heat conduction base plate, wherein the heat conduction base plate, the upper cover body and the lower cover body are all made of copper-aluminum alloy which is corrosion-resistant and has good heat conductivity, a long strip-shaped ventilation groove hole is arranged in the middle of the heat conduction base plate corresponding to the position of each of the solution spraying units, and an upper ventilation fitting hole and a lower ventilation fitting hole are respectively arranged in the middle of the upper cover body and the lower cover body corresponding to the position of the ventilation groove hole, so that the fresh air can pass through each of the heat exchange and humidity control assemblies in the heat exchange and humidity control tower layer by layer through the ventilation groove hole, and at the same time, heat exchange fins are arranged on the surface of the lower cover body, which are also made of copper-aluminum alloy and have high heat conductivity, so as to complete the heat exchange treatment of the air.

[0011] Further, in order to improve the contact efficiency of the salt solution and air, the liquid distribution groove in the solution spraying unit is located inside the ventilation groove hole, and gaps are left between the two sides of the liquid distribution groove and the inner wall of the ventilation groove hole for air to pass through. The spraying holes arranged on the two sides of the liquid distribution groove are arranged at an angle of 45 degrees downward. When air passes through the ventilation groove hole, the salt solution sprayed downward from the two sides of the liquid distribution groove can fully contact with the air in a narrow space, thereby improving the humidification efficiency of the air. At the same time, the wind baffle at the top of the liquid distribution groove is horizontally fixed on the top of the upper cover body and leaves a gap between the wind baffle and the upper cover body for air to pass through. After the fresh air passes through the ventilation groove hole, it is dispersed from the four sides of the wind baffle after being blocked by the wind baffle. On the one hand, it can promote the mixing of fresh air, and on the other hand, it can improve the contact efficiency of fresh air and the heat exchange fins at the bottom of the upper heat exchange assembly, thereby improving the heat exchange effect.

[0012] The end of the solution delivery branch pipe is communicated with the liquid distribution groove, and a first electromagnetic valve is installed on the solution delivery branch pipe. The installation of the first electromagnetic valve on the solution delivery branch pipe in each layer of the heat exchange and humidification assembly can make the heat exchange and humidification integrated mechanism flexibly adjust the solution spraying flow according to actual needs without affecting the air heat exchange effect, so as to change the air humidity.

[0013] Further, in order to improve the air heat exchange effect and avoid large changes in the temperature of the salt solution used for humidification, a sink is integrally formed on the upper and lower surfaces of the heat conduction base plate around the ventilation groove hole, and a liquid guide groove is integrally formed on one surface of the upper cover body and the lower cover body close to the heat conduction base plate corresponding to the position of the sink. After the liquid guide grooves on the upper cover body and the lower cover body and the sinks on the upper and lower surfaces of the heat conduction base plate are assembled, a refrigerant flow guide interlayer is formed. In addition, the upper cover body and the lower cover body are integrally assembled with the heat conduction base plate by seamless jointing. In order to improve the sealing effect of the jointing, a sealing glue is used to assist the sealing at the jointing position. At the same time, a glue sealing groove is integrally formed on the upper and lower surfaces of the heat conduction base plate corresponding to the position of the edge of the upper cover body and the lower cover body, and a sealing ring is arranged in the glue sealing groove. The sealing ring is further arranged on the edge of the ventilation groove hole on the upper and lower surfaces of the heat conduction base plate to ensure the sealing property of the refrigerant flow guide interlayer formed on the upper and lower surfaces of the heat conduction base plate.

[0014] Further, one end of the refrigerant delivery branch pipe is communicated with the refrigerant flow guide interlayer between the upper cover body and the heat-conducting base plate, and one end of the refrigerant recovery branch pipe is communicated with the refrigerant flow guide interlayer between the lower cover body and the heat-conducting base plate, and the heat-conducting base plate is provided with a through hole at both ends located at the groove bottom of the sink, so that the refrigerant flow guide interlayers on the upper and lower surfaces of the heat-conducting base plate can be communicated, which is conducive to the refrigerant flowing from the upper refrigerant flow guide interlayer to the lower refrigerant flow guide interlayer. The refrigerant recovery branch pipe is respectively provided with a surface pressure sensor and a second electromagnetic valve. The surface pressure sensor mainly detects the refrigerant pressure in the heat exchange assembly, and cooperates with the second electromagnetic valve to adjust the refrigerant pressure in each heat exchange and humidification assembly, so as to avoid excessive pressure damaging the sealing between the heat-conducting base plate and the upper and lower cover bodies.

[0015] It should be further explained that, in order to conveniently adjust the air temperature, a third electromagnetic valve (not shown) can also be installed on the refrigerant delivery branch pipe in each heat exchange and humidification assembly, which can not only flexibly adjust the air temperature, but also further prevent sand from entering the heat exchange assembly.

[0016] Further, in order to facilitate the installation of the entire heat exchange and humidification assembly, the heat exchange assembly further comprises an upper frame and a lower frame and a rubber strip frame, and the upper frame and the lower frame are buckled on the edge of the heat-conducting base plate to wrap the edge of the heat-conducting base plate, the upper cover body and the lower cover body, so that the edge structure of the heat exchange and humidification assembly can be effectively attached to the inner wall of the shell, and simultaneously play a sealing effect.

[0017] Further, in order to avoid the salt solution accumulating at the top of each layer of the heat exchange and humidification assembly, the rubber strip frame is fixed on the edge of the upper cover body by waterproof glue to fill the groove between the upper cover body and the upper frame, and the top of the rubber strip frame is inclined towards the middle part of the upper cover body.

[0018] Further, in order to facilitate the installation of the heat exchange and humidification tower and the later maintenance, the shell comprises two oppositely arranged end plates and a solution recovery pool integrally formed at the bottom of the end plates. The solution recovery pool is used to collect the salt solution flowing down from the heat exchange and humidification tower. Meanwhile, the two sides of the two end plates are fixed with detachable coaming plates, and the coaming plates and the end plates form a heat exchange and humidification cabin for installing the heat exchange and humidification tower. The heat exchange and humidification cabin and the solution recovery pool are separated by a grating plate, and filter cotton is laid on the grating plate to filter out dust particles washed out from the air in the salt solution. In addition, the heat exchange and humidification cabin is respectively provided with a ventilated air inlet window at the bottom and an opening for repairing and replacing the filter cotton, and the opening is detachably provided with a mesh plate by screws.

[0019] Further, the bottom of the solution recovery pool is provided with a drain port connected with a solution circulation system in the heat pump type solution dehumidification unit.

[0020] Further, in order to prevent the salt solution from leaking out of the air inlet window along the inner wall of the shell during the falling process, a flow guide strip is installed on the inner wall of the bottom of the heat exchange and humidity control cabin and located above the air inlet window.

[0021] Further, the top of the heat exchange and humidity control cabin is closed by a top cover, and an auxiliary fan is installed in the middle of the top cover. The design of the auxiliary fan is mainly to cooperate with the fan in the heat pump solution dehumidifier unit to ensure that the air can smoothly pass through the heat exchange and humidity control tower to complete heat exchange and humidity adjustment.

[0022] A heat pump solution fresh air unit, comprising the above-mentioned fresh air heat exchange and humidity control integrated mechanism, the input port of the refrigerant booster pump and the end of the refrigerant recovery main pipe are connected with the heat pump circulation system in the heat pump solution fresh air unit.

[0023] Compared with the prior art, the beneficial effects of the present application are as follows:

[0024] Compared with the traditional packed tower spray design, the fresh air heat exchange and humidity control integrated mechanism in the present application adopts a stacked design of multiple heat exchange and humidity control assemblies. Each layer of heat exchange and humidity control assembly is provided with a separate solution spray unit and an air heat exchange mechanism. During the heat exchange and humidity control of air, the temperature of the salt solution sprayed out of the entire heat exchange and humidity control tower from top to bottom can be kept relatively stable and will not change much due to the influence of air heat exchange. The salt solution can maintain a relatively stable humidity control effect, and each layer of heat exchange and humidity control assembly can be controlled independently. Compared with the traditional packed tower spray operation, the flexibility of the entire heat exchange and humidity control mechanism in adjusting the air temperature and humidity is greater, the combination parameter range of the air temperature and humidity is wider, and the precision is higher.

DETAILED DESCRIPTION

[0038] The present application will be described with reference to the drawings attached hereto in which embodiments of the application are shown. The drawings described are intended to be illustrative, and not restrictive, of the present application. Numerous specific details of the apparatus described in this document are set forth in this document. However, it is understood that the application is not limited to the specifics described and that they can be practiced with modifications particular to the apparatus. In order to simplify the present application, some of the conventional structures and components will be shown in the drawings in a simple schematic manner.

[0039] Embodiments:

[0040] In the conventional structure design of the filler tower, the air temperature and humidity adjustment mainly relies on the salt solution. After the salt solution is sprayed from the top of the filler tower, the temperature will change due to the heat exchange with the air, resulting in unstable dehumidification effect of the salt solution, and poor flexibility in adjusting the temperature and humidity. To solve the above problems, a fresh air heat exchange and humidity adjustment integrated mechanism and a heat pump type solution fresh air unit are provided, and the specific scheme is as follows:

[0041] As shown in Figures 1-3 , the fresh air heat exchange and humidity adjustment integrated mechanism provided by the embodiment comprises a shell 1 and a heat exchange and humidity adjustment tower installed inside the shell 1 for heat exchange and humidity adjustment of air. The heat exchange and humidity adjustment tower is composed of a plurality of groups of heat exchange and humidity adjustment assemblies 2 stacked up and down. The heat exchange and humidity adjustment assemblies 2 are spaced apart to facilitate the air to mix in the gap and pass through the upper heat exchange and humidity adjustment assembly 2 again, which not only improves the uniformity of air humidity adjustment, but also improves the air heat exchange efficiency.

[0042] As shown in Figures 5-11 , the heat exchange and humidity adjustment assembly 2 comprises a heat exchange assembly 201 and a mounting bracket 202 fixed to the four corners of the heat exchange assembly 201. The heat exchange and humidity adjustment assembly 2 is mainly installed in the shell 1 through the mounting bracket 202 fixed to the four corners and cooperated with bolts. The top of the heat exchange assembly 201 is provided with a plurality of groups of solution spraying units 203 installed side by side. The solution spraying unit 203 comprises a flat baffle and a liquid distribution groove 231 integrally formed at the bottom of the baffle. The liquid distribution groove 231 is uniformly provided with spraying holes from left to right on both sides, so that the salt solution can be uniformly sprayed from the liquid distribution groove 231 for subsequent air humidity adjustment.

[0043] The heat exchange assembly 201 is also respectively provided with a refrigerant conveying branch pipe 206 and a refrigerant recovery branch pipe 204 at two ends thereof, and one end of each of a plurality of solution spraying units 203 is connected to a solution conveying branch pipe 205, and the solution conveying branch pipe 205 is provided with a first electromagnetic valve 207 for adjusting the spraying flow of the salt solution into the heat exchange assembly 201, wherein specifically, the solution conveying branch pipe 205, the refrigerant conveying branch pipe 206 and the refrigerant recovery branch pipe 204 of each of the heat exchange and humidification assemblies 2 constituting the heat exchange and humidification tower extend to the outside of the shell 1, and each of the solution conveying branch pipe 205, the refrigerant conveying branch pipe 206 and the refrigerant recovery branch pipe 204 in the heat exchange and humidification tower is connected in series by a salt solution conveying main pipe 6, a refrigerant conveying main pipe 7 and a refrigerant recovery main pipe 8, respectively, and an end of the salt solution conveying main pipe 6 is provided with a booster magnetic pump 4, and an end of the refrigerant conveying main pipe 7 is provided with a refrigerant booster pump 5, wherein the booster magnetic pump 4 is used to boost the salt solution treated by the heat pump system and then convey the salt solution to the inside of the heat exchange and humidification tower, so as to ensure that the solution spraying unit 203 in each of the heat exchange and humidification assemblies 2 can uniformly spray the salt solution with sufficient pressure, and the refrigerant booster pump 5 is used to boost the refrigerant entering the inside of the heat exchange and humidification tower, so as to ensure that the refrigerant can smoothly pass through each of the heat exchange assemblies 201.

[0044] In order to complete the air heat exchange effect with the refrigerant, the heat exchange assembly 201 comprises a heat-conducting base plate 213 and an upper cover body 214 and a lower cover body 215 assembled on the upper and lower surfaces of the heat-conducting base plate 213, wherein the heat-conducting base plate 213, the upper cover body 214 and the lower cover body 215 are made of copper-aluminum alloy which is corrosion-resistant and has good heat conductivity, a long strip-shaped ventilation slot hole 2132 is formed in the middle of the heat-conducting base plate 213 corresponding to the position of each of the solution spraying units 203, and an upper ventilation fitting hole 2141 and a lower ventilation fitting hole 2151 are respectively formed in the middle of the upper cover body 214 and the lower cover body 215 corresponding to the position of the ventilation slot hole 2132, so that the fresh air can pass through each of the heat exchange and humidification assemblies 2 in the heat exchange and humidification tower layer by layer from the ventilation slot hole 2132, and at the same time, the heat exchange fins 2152 are arranged on the surface of the lower cover body 215, and the heat exchange fins 2152 are also made of copper-aluminum alloy, and the high heat conductivity of the heat exchange fins 2152 is used to complete the heat exchange treatment of the air.

[0045] In order to improve the contact efficiency of the salt solution and the air, the liquid distribution groove 231 in the solution spraying unit 203 is located inside the ventilation groove hole 2132, and gaps are left between the two sides of the liquid distribution groove 231 and the inner walls of the ventilation groove hole 2132 to facilitate the passage of air. The spraying holes arranged on the two sides of the liquid distribution groove 231 are arranged at an angle of 45 degrees downward. When the air passes through the ventilation groove hole 2132, the salt solution sprayed downward from the two sides of the liquid distribution groove 231 can fully contact the air in a narrow space, thereby improving the humidification efficiency of the air. At the same time, the wind baffle at the top of the liquid distribution groove 231 is horizontally fixed at the top of the upper cover body 214 and leaves a gap between the wind baffle and the upper cover body 214 to facilitate the passage of air. After the fresh air passes through the ventilation groove hole 2132, it is blocked by the wind baffle and flows from the four sides of the wind baffle. On the one hand, it can promote the mixing of the fresh air. On the other hand, it can improve the contact efficiency of the fresh air and the heat exchange fins 2152 at the bottom of the upper heat exchange assembly 201, thereby improving the heat exchange effect.

[0046] The end of the solution delivery branch pipe 205 is in communication with the liquid distribution groove 231, and a first electromagnetic valve 207 is installed on the solution delivery branch pipe 205. The installation of the first electromagnetic valve 207 on the solution delivery branch pipe 205 in each layer of the heat exchange and humidification assembly 2 can make the heat exchange and humidification integrated mechanism flexible to adjust the solution spraying flow according to the actual needs without affecting the air heat exchange effect, thereby changing the air humidity.

[0047] In order to improve the air heat exchange effect and avoid large changes in the temperature of the salt solution used for humidification, the heat conduction base plate 213 is integrally formed with a sink 2134 on the upper and lower surfaces around the ventilation groove hole 2132, and the upper cover body 214 and the lower cover body 215 are integrally formed with a liquid guide groove 2153 on the surface close to the heat conduction base plate 213 corresponding to the position of the sink 2134, so that the liquid guide groove 2153 on the upper cover body 214 and the lower cover body 215 and the sink 2134 on the upper and lower surfaces of the heat conduction base plate 213 form a refrigerant flow guide interlayer after being assembled, and the upper cover body 214 and the lower cover body 215 are integrally assembled with the heat conduction base plate 213 by seamless jointing. In order to improve the sealing effect of the jointing, the jointing seam position is sealed with sealing glue, and the heat conduction base plate 213 is integrally formed with a glue sealing groove 2131 on the upper and lower surfaces corresponding to the position of the edge of the upper cover body 214 and the lower cover body 215, and a sealing ring 216 is arranged in the glue sealing groove 2131. The edge position of the heat conduction base plate 213 on the upper and lower surfaces located in the ventilation groove hole 2132 is also provided with a sealing ring 2133, which further ensures the sealing performance of the refrigerant flow guide interlayer formed on the upper and lower surfaces of the heat conduction base plate 213.

[0048] One end of the refrigerant delivery branch pipe 206 is in communication with the refrigerant flow guide interlayer between the upper cover body 214 and the heat-conducting substrate 213, and one end of the refrigerant recovery branch pipe 204 is in communication with the refrigerant flow guide interlayer between the lower cover body 215 and the heat-conducting substrate 213. The heat-conducting substrate 213 is provided with a perforation 2135 at both ends thereof at the bottom of the groove 2134, so that the refrigerant flow guide interlayers on the upper and lower surfaces of the heat-conducting substrate 213 can be in communication, which is conducive to the refrigerant flowing from the upper refrigerant flow guide interlayer to the lower refrigerant flow guide interlayer of the heat-conducting substrate 213. The refrigerant recovery branch pipe 204 is respectively provided with a pressure sensor 208 and a second electromagnetic valve 209. The pressure sensor 208 is mainly used to detect the refrigerant pressure in the heat exchange assembly 201, and cooperates with the second electromagnetic valve 209 to adjust the refrigerant pressure in each heat exchange and humidification assembly 2, so as to avoid the damage to the sealing between the heat-conducting substrate 213 and the upper cover body 214 and the lower cover body 215 due to the excessive pressure.

[0049] It should be further explained that, in order to facilitate the adjustment of air temperature, a third electromagnetic valve (not shown) can also be installed on the refrigerant delivery branch pipe 206 in each heat exchange and humidification assembly 2, which can not only flexibly adjust the air temperature, but also further prevent the heat exchange assembly 201 from explosion.

[0050] In order to facilitate the installation of the entire heat exchange and humidification assembly 2, the heat exchange assembly 201 further comprises an upper frame 212 and a lower frame 211 and a rubber strip frame 217. The upper frame 212 and the lower frame 211 are buckled at the edges of the heat-conducting substrate 213 to wrap the edges of the heat-conducting substrate 213, the upper cover body 214 and the lower cover body 215, so that the edge structure of the heat exchange and humidification assembly 2 can be effectively attached to the inner wall of the shell 1, and simultaneously achieve the sealing effect.

[0051] In order to avoid the accumulation of salt solution at the top of each layer of the heat exchange and humidification assembly 2, the rubber strip frame 217 is fixed to the edge of the upper cover body 214 by waterproof glue to fill the groove between the upper cover body 214 and the upper frame 212, and the top of the rubber strip frame 217 is inclined towards the middle part of the upper cover body 214.
