Through set up gas-liquid heat exchanger in drying system, this application can alleviate the burden of evaporimeter, guarantees the dehumidification ability of evaporimeter, shortens the stoving time, reduces the stoving energy consumption.
Specifically, an air inlet and an air outlet of the gas-liquid heat exchanger are respectively communicated with a wet air outlet and an inlet of the evaporator, a liquid inlet and a liquid outlet are respectively communicated with the water receiving tray, when the drying system works, the compressor, the fan and the water pump are started to operate, the compressor pushes the refrigerant to circulate along the refrigerant circulation loop, the water pump drives the condensed water in the water receiving tray to circulate along the cooling circulation loop, and the fan drives the air flow to circulate in the air circulation loop. The humid air in the drying chamber is sucked into the humid air outlet, the humid air firstly enters the gas-liquid heat exchanger through the air inlet, and exchanges heat with the condensed water in the cooling circulation loop in the gas-liquid heat exchanger to reduce the temperature, so that the primary cooling is realized, the temperature of the corresponding condensed water is raised, the recycling of cold energy in the condensed water is realized, and the waste of energy is reduced. The wet air with the primarily reduced temperature is discharged from the gas-liquid heat exchanger through the gas outlet and continuously flows forwards to the evaporator, the wet air is subjected to heat exchange with the refrigerant in the evaporator to realize secondary temperature reduction, the temperature of the air is reduced to be below the dew point temperature, water is separated out, and the air becomes condensed water and is dripped into the water pan. Because the humid air is not directly sent to the evaporator for heat exchange in the process, but is firstly subjected to heat exchange with the low-temperature condensed water inside through the gas-liquid heat exchanger, the temperature of the humid air reaching the evaporator is lower than that of the humid air directly sent to the evaporator, namely, the sensible heat burden of the evaporator is lightened, the dehumidification efficiency of the drying system is improved, meanwhile, the condensed water absorbs the heat of the humid air, the latent heat of the condensed water is recovered by the system, the condition that the low-temperature condensed water is not effectively utilized is avoided, the energy loss is reduced, the circulation efficiency of the system is improved, and the energy consumption is reduced.
Further, through adopting shell-and-tube heat exchanger for the gas-liquid heat exchanger of this application has advantages such as heat transfer coefficient is high, heat transfer rate is fast, occupation space is little, longe-lived.
Further, through set up the baffling board in shell and tube type heat exchanger for the inside baffling passageway that forms of casing can increase the heat transfer area of air and heat exchange tube, thereby improves the heat transfer effect by a wide margin, and then reduces the burden of evaporimeter, improves the dehumidification efficiency of system.
Further, through set up the runner that the baffle separates casing internal partitioning for the U type in the casing, can make air and heat exchange tube fully contact, further improve the heat transfer effect.
Further, through setting up air inlet and gas outlet in the week side of casing and correspond the one end of U type runner respectively to and all set up inlet and liquid outlet on the terminal surface that the casing is close to the free end of U type pipe, make the air can with the heat exchange tube maximum carry out the heat exchange after getting into shell and tube type heat exchanger, improve the heat transfer effect.
Furthermore, the air inlet is arranged on the shell close to the upstream end of the U-shaped flow channel, the air outlet is arranged on the shell close to the downstream end of the U-shaped flow channel, the liquid inlet is arranged on the shell close to the downstream end of the U-shaped pipe, and the liquid outlet is arranged on the shell close to the upstream end of the U-shaped pipe, so that the flowing direction of air is opposite to the flowing direction of condensed water, the countercurrent exchange between the air and the condensed water is realized, and the heat exchange effect is better.
Furthermore, because the condensed water is liquid, the pressure drop is small, the air is gas, and the pressure drop is large, the area of the air inlet is larger than the areas of the liquid inlet and the liquid outlet, the area of the air outlet is larger than the areas of the liquid inlet and the liquid outlet, the pressure drop of the air can be reduced, and a good flow heat exchange effect is realized.
Furthermore, the drying system is provided with the overlapping heat exchanger, so that the drying system can improve the heat exchange efficiency of the evaporator and the condenser at the same time, and higher dehumidification efficiency and lower energy consumption are realized.
Specifically, a first inlet of the cascade heat exchanger is communicated with a wet air outlet, a first outlet is communicated with an air inlet of the gas-liquid heat exchanger, a second inlet is communicated with an outlet of the evaporator, and a second outlet is communicated with an inlet of the condenser, so that wet air firstly exchanges heat with low-temperature dry air flowing out of the evaporator through the cascade heat exchanger before entering the gas-liquid heat exchanger for cooling, the temperature of the low-temperature dry air is greatly reduced, the temperature of the low-temperature dry air is simultaneously raised (equal heat exchange in the process), the reduced wet air continuously and sequentially flows to the gas-liquid heat exchanger and the evaporator for secondary and tertiary cooling to reach below a dew point temperature, moisture in the air is greatly separated out, and the wet air is not directly sent to the evaporator for heat exchange in the process, but exchanges heat with the low-temperature dry air from the evaporator through the cascade heat exchanger, then the wet air reaches the evaporator and has much lower temperature than the wet air directly sent to the evaporator, thus greatly reducing the burden of the evaporator and improving the dehumidification efficiency, and the inventor repeatedly tests, observes, analyzes and compares the wet air and the wet air, and can realize the significant improvement of the whole dehumidification efficiency by more than 15 percent when the overlapping heat exchanger and the gas-liquid heat exchanger are adopted at the same time.
Meanwhile, because the low-temperature dry air flowing out of the evaporator exchanges heat with the wet air, the temperature of the air entering the condenser is higher than that of the air directly entering the condenser without the overlapping heat exchanger, and the temperature of the air which is discharged from the condenser and enters the drying chamber again is higher than that of the air which is not discharged from the overlapping heat exchanger, so that the temperature of the air entering the drying chamber is also increased by the overlapping heat exchanger, the drying speed of clothes is correspondingly increased, the drying efficiency is further improved, and the energy consumption is further reduced.
The application of the clothes treatment equipment can remarkably improve the drying efficiency and reduce the drying energy consumption by setting the drying system.

Example 2
A second embodiment of the drying system of the present application will be described with reference to fig. 3. Fig. 3 is a system diagram of a drying system according to a second embodiment of the present invention.
As shown in fig. 3, on the premise of keeping the other structural arrangements unchanged in embodiment 1, the drying system further includes a cascade heat exchanger 22, where the cascade heat exchanger 22 has a first inlet 221, a first outlet 222, a second inlet 223 and a second outlet 224, one air flow channel is formed between the first inlet 221 and the first outlet 222, another air flow channel is formed between the second inlet 223 and the second outlet 224, and the two air flow channels are arranged to intersect with each other, so as to be able to exchange heat in a cross-flow manner. The first inlet 221 communicates with the humid air outlet 211, the first outlet 222 communicates with the air inlet 2311 of the liquid-gas heat exchanger 23, the second inlet 223 communicates with the outlet of the evaporator 14, and the second outlet 224 communicates with the inlet of the condenser 12. The specific structural form of the cascade heat exchanger 22 is not limited in the present application, and any heat exchanger that can satisfy the above conditions can be applied to the present application as the cascade heat exchanger 22. For example, a plate-fin heat exchanger or a heat wheel heat exchanger may be used as the cascade heat exchanger 22 of the present application.
According to the orientation shown in fig. 3, the high-temperature humid air discharged from the humid air outlet 211 flows into one air flow passage of the cascade heat exchanger 22 through the first inlet 221 of the cascade heat exchanger 22 before entering the air-liquid heat exchanger 23 for cooling, the low-temperature dry air flowing out of the evaporator 14 flows into the other air flow passage of the cascade heat exchanger 22 through the second inlet 223 of the cascade heat exchanger 22, and the two air flows into the air flow passage for heat exchange, so that the temperature of the high-temperature humid air is lowered, and the temperature of the low-temperature dry air is raised at the same time (the process is equivalent heat exchange). Then, the wet air whose temperature has been lowered continues to flow forward to the gas-liquid heat exchanger 23 for secondary temperature lowering, and at the same time, the dry air whose temperature has been raised continues to flow forward to the condenser 12 for secondary temperature raising.
It can be seen that by providing the drying system with the cascade heat exchanger 22, the drying system can simultaneously improve the heat exchange efficiency between the evaporator 14 and the condenser 12, and achieve higher dehumidification efficiency and lower energy consumption.
Specifically, before entering the gas-liquid heat exchanger 23 for cooling, the wet air firstly passes through the cascade heat exchanger 22 to perform heat exchange with the low-temperature dry air flowing out of the evaporator 14, the temperature of the wet air is greatly reduced, the temperature of the low-temperature dry air is simultaneously raised (the process is equivalent heat exchange), the wet air with the reduced temperature continuously and sequentially flows to the gas-liquid heat exchanger 23 and the evaporator 14 for secondary and tertiary cooling to reach the dew point temperature below, the moisture in the air is greatly separated out, because the wet air is not directly sent to the evaporator 14 for heat exchange in the process, but firstly passes through the cascade heat exchanger 22 to perform heat exchange with the low-temperature dry air from the evaporator 14, then passes through the gas-liquid heat exchanger 23 for secondary heat exchange, and finally enters the evaporator 14 for heat exchange, therefore, the temperature of the wet air reaching the evaporator 14 is much lower than that of the wet air directly sent to the evaporator 14, therefore, the burden of the evaporator 14 is greatly reduced, the dehumidification efficiency is improved, and the significant improvement of the overall dehumidification efficiency by more than 15% can be realized when the cascade heat exchanger 22 and the gas-liquid heat exchanger 23 are adopted simultaneously through repeated tests, observation, analysis and comparison of the inventor.
Meanwhile, since the low-temperature dry air flowing out of the evaporator 14 exchanges heat with the wet air, the temperature of the air entering the condenser 12 is higher than that of the air directly entering the condenser 12 without the overlapping heat exchanger 22, and thus the temperature of the air discharged from the condenser 12 and entering the drying chamber 21 again is higher than that of the air without the overlapping heat exchanger 22, and therefore, the arrangement of the overlapping heat exchanger 22 also increases the temperature of the air entering the drying chamber 21, accordingly, the drying speed of the clothes is increased, the drying efficiency is further improved, and the energy consumption is further reduced.

For example, in an alternative embodiment, the specific arrangement of the shell-and-tube heat exchanger is not limited to the above-mentioned arrangement, and may be modified by those skilled in the art as long as the arrangement is capable of performing heat exchange between the condensed water and the air.

For another example, in another alternative embodiment, the arrangement of the evaporator 14, the condenser 12 and the fan 24 is not constant, and those skilled in the art can make modifications to the arrangement of the above components without departing from the principles of the present application, provided that the air circulation loop can be formed. For example, one or more of the evaporator 14, the condenser 12, and the fan 24 may also be disposed directly inside the air duct 25.
For another example, in another alternative embodiment, although the above embodiment is illustrated as a shell-and-tube heat exchanger, the embodiment of the gas-liquid heat exchanger 23 is not limited thereto, and those skilled in the art can select the heat exchanger based on the actual application scenario, i.e. the effect is not significant compared with the shell-and-tube heat exchanger. For example, the gas-liquid heat exchanger 23 may be a plate heat exchanger or a double pipe heat exchanger, and when the double pipe heat exchanger is used, the outer pipe may be set to be an air-away pipe, and the inner pipe may be a condensed water-away pipe, so as to take account of the flowing heat exchange effect.
