Description

Technical Field

[0001] This utility model relates to the field of temperature-controlled dehumidifier technology, specifically a dual-cold-source temperature-controlled dehumidifier. Background Technology

[0002] A dehumidifier is a device used to reduce indoor humidity. Temperature-regulating dehumidifiers are highly efficient and energy-saving devices that integrate dehumidification and temperature regulation functions. When humid indoor air passes through the evaporator, water vapor condenses and is discharged through the water pipe because the evaporator's temperature is lower than the dew point temperature of the humid air, thus achieving dehumidification. The dehumidified air then passes through the condenser to raise its temperature, further reducing the relative humidity and achieving the purpose of drying the air.

[0003] Currently, temperature-regulating dehumidifiers mainly use a four-way valve to switch between cooling and heating modes, and control the temperature rise of the air in the air-cooled condenser by adjusting the cooling water flow of the water-cooled condenser, thereby achieving regulation of indoor temperature and humidity in different modes. However, this mode cannot precisely control the temperature of the air after it has been heated. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1 and Figure 2 As shown, this utility model discloses a dual-cold-source temperature-regulating dehumidifier, including: a casing 1 and a fan 2, a condenser, an evaporator 5 and a compressor 6 installed inside the casing 1. There are two condensers, namely a first condenser 3 and a second condenser 4.

[0028] In this embodiment, the evaporator 5 is a finned evaporator, the first condenser 3 is a finned condenser, and the second condenser 4 is a plate condenser. In some other embodiments, the second condenser 4 may also be a shell-and-tube condenser.

[0029] Combination Figure 3 and Figure 4 As shown, a water tank 7 is also installed inside the casing 1. The fan 2, the first condenser 3 and the evaporator 5 are installed above the water tank 7. The fan 2 draws in humid air, which is condensed into condensate by the evaporator 5 and then drips into the water tank 7.

[0030] The second condenser 4 and the compressor 6 are installed below the water tank 7, and the water tank 7 is connected to the second condenser 4. Condensate is injected into the second condenser 4 as refrigerant, and a proportional solenoid valve 8 is installed between the water tank 7 and the second condenser 4 to control the water inflow.

[0031] Simultaneously, the evaporator 5 is connected to the compressor 6, which converts the low-temperature, low-pressure refrigerant in the evaporator 5 into a high-temperature, high-pressure state. The compressor 6 is also connected to the second condenser 4, which regulates the temperature of the high-temperature, high-pressure refrigerant. The second condenser 4 is also connected to the first condenser 3, which heats the air using the regulated refrigerant. Furthermore, a throttling device 9 is installed between the first condenser 3 and the evaporator 5 to convert the refrigerant into a low-temperature, low-pressure state, thus forming a cycle.

[0032] like Figure 5 As shown, in this embodiment, the first condenser 3 is provided with a first refrigerant inlet 31 and a first refrigerant outlet 32, the second condenser 4 is provided with an air inlet 43 and an exhaust outlet 44, the evaporator 5 is provided with a third refrigerant inlet 51 and a third refrigerant outlet 52, and the compressor 6 is provided with a fourth refrigerant inlet 61 and a fourth refrigerant outlet 62.

[0033] The third refrigerant outlet 52 is connected to the fourth refrigerant inlet 61, the third refrigerant inlet 51 is connected to the first refrigerant outlet 32, the first refrigerant inlet 31 is connected to the exhaust port 44, and the air inlet 43 is connected to the fourth refrigerant outlet 62, forming a cycle.

[0034] In this embodiment, an electronic expansion valve is provided between the first condenser 3 and the evaporator 5 as a throttling device 9, and the electronic expansion valve is installed between the first refrigerant outlet 32 ​​and the third refrigerant inlet 51. In some other embodiments, a capillary tube can also be provided between the first condenser 3 and the evaporator 5 as a throttling device 9.

[0035] Secondly, the second condenser 4 is also provided with a second refrigerant inlet 41 and a second refrigerant outlet 42, and a drain outlet 71 is provided at the bottom of the water tank 7. The second refrigerant inlet 41 is connected to the drain outlet 71, and a proportional solenoid valve 8 is installed between the second refrigerant inlet 41 and the drain outlet 71.

[0036] like Figure 6 As shown, in this embodiment, the dual-source temperature-regulating dehumidifier further includes a water tank 10, which is connected to the second refrigerant outlet 42. The casing 1 has a closable opening 11 on one side of the water tank 10 to remove the water tank 10 for drainage.

[0037] like Figure 7As shown, in some other embodiments, the bottom of the water tank 7 is also provided with a water inlet 72, and the water inlet 72 and the second refrigerant outlet 42 are respectively connected to the water tank 10, so as to realize the circulation of condensate while delaying the drainage time of the water tank 10.

[0038] The working principle of this utility model mainly consists of two parts: dehumidification and heating. The working principle of dehumidification is as follows: First, humid air is drawn into the casing 1 by the fan 2. When the humid air encounters the evaporator 5, the water vapor in the air condenses into condensate and drips into the water tank 7 in the casing 1 because there is a low-temperature and low-pressure refrigerant inside the evaporator 5.

[0039] Secondly, since the water tank 7 is connected to the second condenser 4, the condensate is discharged from the water tank 7 into the second condenser 4 as the refrigerant of the second condenser 4 to participate in the heat exchange process and then discharged.

[0040] With the water tank 10 installed, the condensate, after participating in the heat exchange process, can be stored in the water tank 10 and drained when the water tank 10 is full. Alternatively, with the water tank 10 installed, an inlet 72 can be installed at the bottom of the water tank 7. By installing the water tank 10 between the second condenser 4 and the water tank 7, the condensate that has participated in the heat exchange process dissipates heat in the water tank 10. When the water tank 10 is full, it can be drained back into the water tank 7, thus achieving condensate circulation and delaying the drainage time of the water tank 10.

[0041] The working principle of heating is as follows: First, the low-temperature, low-pressure refrigerant in the evaporator 5 is drawn into the compressor 6 and transformed into a high-pressure, high-temperature state under the action of the compressor 6. Then, the high-temperature, high-pressure refrigerant is transported by the compressor 6 to the second condenser 4 for temperature regulation.

[0042] At this time, the proportional solenoid valve 8 between the water tank 7 and the second condenser 4 controls the amount of condensate entering the tank according to the set temperature, and changes the temperature of the refrigerant through heat exchange between the condensate and the refrigerant.

[0043] Secondly, the refrigerant that has undergone heat exchange is discharged from the second condenser 4 and enters the first condenser 3. At this time, the dehumidified air encounters the first condenser 3, and the dehumidified air is heated through heat exchange between the refrigerant in the first condenser 3 and the air. Then the heated air is discharged.

[0044] Finally, after exchanging heat with the air, the refrigerant in the first condenser 3 is transformed into a normal temperature and high pressure state. At this time, the refrigerant is transported to the evaporator 5 through the throttling device 9. After passing through the throttling device 9, the refrigerant in the normal temperature and high pressure state is transformed into a low temperature and low pressure state, and then stored in the evaporator 5 to prepare for the next condensation.

[0045] The above description is only a preferred embodiment of the present utility model. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
