Description

Technical Field

[0001] The utility model belongs to the technical field of dehumidifier refrigeration, and particularly relates to a double-stage refrigeration ceiling dehumidifier for preventing condensation. Background Art

[0002] To enhance dehumidification, dehumidifiers use a two-stage cooling system to cool the air they process. This double cooling process typically reduces the air temperature to below 12°C, often dropping below 5°C during the transitional and rainy seasons. This causes a large amount of condensate to form, and the temperature of the condensate is very low, typically around 8°C, though it can drop even lower, even below 2°C, during the transitional and rainy seasons. This condensate is collected in the unit's condensate pan and then discharged through the condensate drain. This low condensate temperature also causes the condensate pan to be very low. During actual use, this can cause condensation to form on the unit casing around the pan and condensate outlet. This persistent condensation can cause dripping, causing problems for both home decor and daily life. Furthermore, the condensate discharge piping requires enhanced insulation, as condensation can accumulate in areas with weak insulation, causing inconvenience and discomfort.

[0003] Therefore, the above problems constitute technical problems that need to be solved urgently. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the utility model provides a two-stage refrigeration ceiling dehumidifier that prevents condensation. It has a reasonable design and a simple structure and can heat the water in the condensation water tray without condensation.

[0005] Technical solution: In order to achieve the above-mentioned purpose, the utility model provides a two-stage refrigeration ceiling dehumidifier for preventing condensation, including a primary refrigeration system and a secondary refrigeration system, the primary refrigeration system including a primary compressor, a primary condenser and a primary evaporator, the primary condenser and the primary evaporator are respectively provided with a condenser coil and an evaporator coil, the refrigerant outlet of the primary compressor is connected to the condenser coil inlet, the outlet of the condenser coil is connected to the evaporator coil inlet, and the outlet of the evaporator coil is connected to the refrigerant inlet of the primary compressor; the refrigerant in the cooling system is discharged from the compressor outlet in the form of high-temperature and high-pressure gas and enters the condenser to become a low-temperature and high-pressure gas. This process releases heat, causing the air passing through it to heat up, and then the refrigerant passes through the throttling element to become a low-temperature and low-pressure liquid and absorbs heat through the evaporator. The air passing through the evaporator is cooled and the moisture carried is condensed.

[0006] The dehumidifier also includes a condensate pan located below the primary evaporator. A heating pipe is installed in the connecting pipe between the primary condenser and the primary evaporator, and the heating pipe is located in the condensate pan. Condensed water from the evaporator flows into the condensate pan. During operation, the high temperature of the heating pipe heats the condensate in the condensate pan, preventing condensation outside the condensate pan. This also raises the temperature of the discharged condensate, preventing condensation outside of the drainpipe and other pipes. Finally, the refrigerant flows back to the compressor.

[0007] Furthermore, the heating pipe coil is arranged in a condensed water tray, and a condensed water outlet is provided on the condensed water tray. The heating pipe is arranged in a zigzag reciprocating structure in the condensed water tray, thereby increasing the heating area and achieving a more obvious anti-condensation effect.

[0008] Furthermore, the secondary refrigeration system includes a secondary compressor, a secondary condenser, and a secondary evaporator. The refrigerant outlet of the secondary compressor is connected to the inlet of the secondary condenser, the outlet of the secondary condenser is connected to the inlet of the secondary evaporator, and the outlet of the secondary evaporator is connected to the refrigerant inlet of the secondary compressor. The dehumidification effect of the dehumidifier is enhanced by the cooperation of the primary refrigeration system and the secondary refrigeration system.

[0009] Furthermore, the dehumidifier further includes a wind-induction system, which includes an air inlet, a fan, and an air outlet. The fan is located between the air inlet and the air outlet and is close to the air outlet. Under the action of the fan, external air enters the dehumidifier from the air inlet and is exhausted from the air outlet, thus achieving external air circulation.

[0010] Furthermore, a primary evaporator, a secondary evaporator, a secondary condenser, and a fan are sequentially arranged between the air inlet and the fan, with the primary condenser being located on the side of the primary evaporator. After entering through the air inlet, moist air from the outside is cooled and condensed in the primary and secondary evaporators, becoming cool and dry. The air then heats up in the secondary condenser, becoming dry and warm, before returning to the outside environment through the air outlet.

[0011] Furthermore, the heating tube and the evaporator coil inlet, as well as the secondary condenser and the secondary evaporator, are connected via throttling elements, which are capillary tubes or throttle valves. The throttling elements convert the low-temperature and high-pressure gas refrigerant passing through them into low-temperature and low-pressure liquid refrigerant.

[0012] Furthermore, the primary condenser is a water-cooled condenser, and a cooling water inlet and outlet are provided on the primary condenser.

[0013] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0014] 1. The utility model provides a two-stage refrigeration ceiling dehumidifier that prevents condensation. It has a simple structure and adopts a two-stage refrigeration system to enhance the dehumidification effect. At the same time, a heating pipe is provided on the connecting pipe between the primary compressor and the primary evaporator. The heating pipe is located in the condensate water pan. When the dehumidifier is in operation, the heat emitted by the heating pipe is used to heat the condensed water in the condensate water pan to prevent condensation on the outside of the condensate water pan and the drain pipe.

[0015] 2. On the other hand, the condensed water cools the heating pipe, that is, it cools the refrigerant in the pipe, reduces the condensation pressure, and improves the refrigeration efficiency; it also increases the subcooling degree of the refrigerant before throttling, and improves the stability of operation.

[0020] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] like Figure 1-2 As shown: A two-stage refrigeration ceiling dehumidifier for preventing condensation includes a primary refrigeration system and a secondary refrigeration system. The primary refrigeration system includes a primary compressor 1, a primary condenser 2, and a primary evaporator 3. A condenser coil and an evaporator coil are respectively provided in the primary condenser 2 and the primary evaporator 3. The refrigerant outlet of the primary compressor 1 is connected to the condenser coil inlet, the condenser coil outlet is connected to the evaporator coil inlet, and the evaporator coil outlet is connected to the refrigerant inlet of the primary compressor 1.

[0022] It also includes a condensed water pan 4 , which is arranged below the primary evaporator 3 . A heating pipe 5 is provided on the connecting pipeline between the primary condenser 2 and the primary evaporator 3 , and the heating pipe 5 is located in the condensed water pan 4 .

[0023] The heating tube 5 is disposed in a condensed water tray 4 , and a condensed water outlet 41 is provided on the condensed water tray 4 .

[0024] Please refer to Figure 1 The secondary refrigeration system includes a secondary compressor 6, a secondary condenser 7 and a secondary evaporator 8. The refrigerant outlet of the secondary compressor 6 is connected to the inlet of the secondary condenser 7, the outlet of the secondary condenser 7 is connected to the inlet of the secondary evaporator 8, and the outlet of the secondary evaporator 8 is connected to the refrigerant inlet of the secondary compressor 6.

[0025] In addition, it also includes a phoenix attracting system, which includes an air inlet 9, a fan 10 and an air outlet 11. The fan 10 is arranged between the air inlet 9 and the air outlet 11 and is close to the air outlet 11.

[0026] Please refer again Figure 1 The primary evaporator 3 , the secondary evaporator 8 , the secondary condenser 7 and the fan 10 are sequentially arranged between the air inlet 9 and the fan 10 , and the primary condenser 2 is arranged on the side of the primary evaporator 3 .

[0027] like Figure 3 As shown, the heating tube 5 and the evaporator coil inlet, as well as the secondary condenser 7 and the secondary evaporator 8, are connected via a throttling element 12, which is a capillary tube or a throttle valve. In this embodiment, the throttling element 12 is a capillary tube, which reduces pressure by the resistance generated when fluid passes through a small pipe. However, a capillary tube is composed of a long, thin tube, typically with a diameter between 0.5 and 2.5 mm. Its flow control capability is limited and cannot be adjusted once installed. A throttle valve, on the other hand, is a valve that can adjust the flow rate by changing the valve opening. A throttle valve controls the flow rate by changing the valve opening and can be adjusted according to system requirements. Users can make a reasonable choice of this element based on the usage scenario. For example, capillary tubes are commonly used in small refrigeration equipment, such as household air conditioners and refrigerators, due to their simple structure and low cost. Throttle valves, on the other hand, are more suitable for use in large refrigeration systems or those requiring precise control due to their adjustability.

[0028] More preferably, the primary condenser 2 in this embodiment is a water-cooled condenser, provided with a cooling water inlet and outlet. A water-cooled condenser uses water as a cooling medium. Since water is generally cold in nature, the condensation temperature of a water-cooled condenser is relatively low, which is beneficial to the refrigeration capacity and economical operation of the compressor.

[0029] The utility model provides a double-stage refrigeration ceiling dehumidifier for preventing condensation, which has a good dehumidification effect. A heating pipe is added to utilize the heat released by the condenser to heat the water in the condensation water tray, thereby avoiding external condensation. At the same time, the condensed water can cool the refrigerant in the heating pipe, reducing the condensation pressure and improving the refrigeration efficiency.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as within the scope of protection of the present invention.
