Description

Technical Field

[0001] The utility model relates to a temperature-raising energy-saving dehumidification unit, belonging to the technical field of dehumidification units. Background Art

[0002] Dehumidifiers are common electrical appliances, widely used for indoor humidity regulation and dehumidification. Compared to other types of dehumidifiers, heating-type dehumidifiers offer the advantages of high dehumidification efficiency and low energy consumption. They are also suitable for low-temperature environments. Under low-temperature conditions, traditional dehumidifiers will further lower the indoor temperature. Heating-type dehumidifiers can prevent the room temperature from dropping during use, making them suitable for winter or cold storage environments requiring a constant temperature. Heating-type dehumidifiers can maintain a dry environment during use, helping to prevent the growth of mold and bacteria. They are suitable for locations requiring a constant temperature and humidity, such as archives and storage rooms. During use, heating-type dehumidifiers recycle the internal energy in the air, eliminating the need for additional heating equipment and saving energy.

[0003] Existing heating-type dehumidifiers process heat and humidity in air as follows: the air to be treated first passes through the evaporator, where the moisture in the air is condensed into liquid and discharged through the condenser pipe, thereby reducing the indoor humidity load and simultaneously lowering the air temperature. The air then passes through the condenser to raise its temperature before being delivered to the room by the blower, completing the cycle. A heating-type dehumidifier has an evaporator inside. To ensure optimal dehumidification, the air volume passing through the evaporator should be low, given a certain compressor displacement. To maintain a certain cooling system energy efficiency, the air volume passing through the condenser should be high, to reduce condensing pressure.

[0004] Existing solutions treat equal air volumes passing through the evaporator and condenser. If optimal dehumidification is to be achieved, the low air volume will result in high condensing pressure in the refrigeration system, forcing the compressor to operate at a high compression ratio, resulting in poor energy efficiency. If optimal refrigeration system energy efficiency is to be achieved, dehumidification capacity will be suboptimal due to the high air volume. Therefore, existing solutions compromise on air volume, ultimately resulting in neither optimal dehumidification capacity nor optimal refrigeration system energy efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a temperature-raising energy-saving dehumidification unit, which solves the problem that the air volume passing through the evaporator and the condenser cannot be adjusted and the working efficiency of the dehumidification unit is low.

[0006] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: a heating type energy-saving dehumidification unit, comprising

[0007] Box, refrigeration system, heat pipe system, air supply system,

[0008] The refrigeration system, the heat pipe system, and the air supply system are all fixed in the box.

[0009] The heat pipe system includes a first evaporator, a first condenser, and a heat pipe pipeline;

[0010] The refrigeration system includes a second evaporator, a second condenser, a compressor, an expansion valve, and a refrigeration pipeline;

[0011] Refrigerant is provided inside the heat pipe system and the refrigeration system;

[0012] The air supply system includes an air blower;

[0013] A bypass air valve is also provided inside the box, and the total air volume entering the box is kept constant, which is divided into a first air duct and a second air duct, wherein the air volume of the first air duct is adjusted by the bypass air valve, and the second air duct does not flow through the bypass air valve. The air flowing through the first air duct passes through the first evaporator, the second evaporator, and the first condenser in sequence and is mixed with the air flowing through the second air duct; the second air duct is mixed with the first air duct, and the mixed air passes through the second condenser and is sent out of the box through the blower.

[0014] Preferably, when the bypass air valve adjusts the air volume of the first air duct, the air volume of the second air duct changes accordingly.

[0015] Preferably, the refrigerant flows in the heat pipe system by gravity or pump drive.

[0016] Preferably, the refrigerant circulates in the refrigeration pipe through the compressor.

[0017] Preferably, the refrigerant can absorb the coldness of the first condenser and transfer it to the first evaporator.

[0018] Preferably, the refrigerant can absorb the cooling capacity of the second condenser and transfer it to the second evaporator.

[0019] The beneficial effects of the utility model are:

[0020] (1) Through the present invention, a refrigeration system and a heat pipe system are provided inside the dehumidifier unit. The refrigeration system can lower the air temperature and condense the moisture in the air. By adding a heat pipe system inside the dehumidifier unit, the heat pipe system can assist the refrigeration system in working and reduce the compressor configuration capacity of the refrigeration system.

[0021] (2) According to the present invention, a bypass vent is provided on the dehumidifier unit. The air entering the dehumidifier unit is divided into a first air duct and a second air duct through the bypass vent. After passing through the bypass vent, the first air duct passes through the first evaporator, the second evaporator, and the first condenser in sequence, and then is mixed with the air in the second air duct that has only passed through the bypass vent. The mixed air enters the second condenser and is then sent out of the dehumidifier unit by the blower. The bypass vent can adjust the ratio of the first air duct and the second air duct, so that the processed air volume passing through the evaporator is separated from the processed air volume passing through the condenser. While ensuring the best dehumidification effect, more processed air volume can pass through the condenser, reducing the condensing pressure of the refrigeration system and improving the energy efficiency of the refrigeration system.

[0022] (3) Through the present invention, a certain height difference is formed between the first evaporator and the first condenser in the heat pipe system. The refrigerant in the heat pipe system uses this height difference to assist the steam to rise and the liquid to reflux, thereby reducing circulation resistance and energy loss and improving the heat transfer efficiency of the heat pipe. This can reduce or eliminate the need for additional mechanical equipment to promote liquid flow, reduce system energy consumption, and further enhance energy conservation.

[0027] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0028] Example 1

[0029] like Figure 1-Figure 3 As shown, a temperature-raising energy-saving dehumidification unit includes a box body, a refrigeration system, a heat pipe system, and an air supply system, wherein the refrigeration system, the heat pipe system, and the air supply system are all fixed in the box body.

[0030] In this embodiment, the box body adopts a vertical cabinet structure, which can utilize space to a greater extent. More system components are arranged inside the dehumidification unit. The box body adopts a vertical cabinet design, which can more effectively utilize the ground space; the box body needs to circulate the air in the room, and the vertical cabinet structure can facilitate convection and better air circulation.

[0031] The heat pipe system includes a first evaporator 21 and a first condenser 22; the refrigeration system includes a second evaporator 31, a second condenser 32, a compressor 33, and an expansion valve 34; and refrigerant is provided in both the heat pipe system and the refrigeration system.

[0032] The heat pipe system and the refrigeration system are both installed inside the housing, and are independent of each other. Specifically, the first evaporator 21 and the second evaporator 31 are installed in a fitted manner, and the first evaporator 21 and the second evaporator 31 are both fixed to the bottom of the housing 1. In this embodiment, the first evaporator 21 and the second evaporator 31 are fitted together and placed at an angle, with the first evaporator 21 fixed below and the second evaporator 31 placed above the first evaporator 21. The first condenser 22 is arranged at the upper end of the second evaporator 31, with one end of the first condenser 22 fitting against one end of the second evaporator 31. The first condenser 22 is also arranged at an angle, with the first condenser 22 and the second evaporator 31 tilted in opposite directions. The second condenser 32 is arranged on top of the first condenser 22.

[0033] A bypass vent valve 1 is further provided inside the housing. The bypass vent valve 1 is provided at the top of one inclined end of the first evaporator 21 and is connected to the housing 1 .

[0034] A return air filter 4 is provided at the bottom of one side of the box body near the bypass air valve 1 , a blower 5 is provided on the top of the second condenser 32 , and an air outlet 7 is provided at one end of the box body near the blower 5 .

[0035] In this embodiment, a control device is provided at one end of the housing away from the air outlet 7. A refrigeration system is provided within the housing. Specifically, a compressor 33 is provided at the bottom of the housing. The compressor 33 is connected to the second evaporator 32 and the second condenser 33 via refrigeration pipes. Refrigerant is provided in the refrigeration pipes, and an expansion valve is provided on the refrigeration pipes near the compressor 33. The refrigerant in the refrigeration system circulates through the refrigeration pipes, the second evaporator 32, and the second condenser 33 via the compressor 33.

[0036] A heat pipe system is also provided inside the box, specifically, a first evaporator 21, a first condenser 32, and a heat pipe are provided on one side of the box near the bottom.

[0037] The first evaporator 21 and the second evaporator 31 are positioned close together, with their top ends facing the return air filter 4. Their bottom ends are aligned with the bottom end of the housing, away from the return air filter 4. A bypass damper 1, mounted on top of the first evaporator 21, has one end connected to the first evaporator 21 and the other end connected to the housing, and is fixed to the top of the return air filter 4.

[0038] In this embodiment, the first condenser 32, which is mounted on top of the second evaporator 31, has one end of its bottom abutted against the second evaporator 31 and the other end abutted against the housing. The first condenser 22 is tilted. The tilt is in the opposite direction of the first and second evaporators 21, 31. When the first and second evaporators 21, 31 are attached, a space of a certain size is formed between them and the first condenser 22, allowing air to flow through this space.

[0039] One end of the second condenser 32 arranged on the top of the first condenser 22 is connected to the box, and the other end is connected to the first condenser 22. The air entering the box from the return air filter 4 passes through the second condenser 32 and is sent out of the box from the air outlet 7 through the blower 5.

[0040] Reference Figure 3 The return air filter 4 can filter the air entering the box. After entering the box, the air is divided into the first air duct and the second air duct. The sum of the air volume passing through the first air duct and the air volume passing through the second air duct is the air entering the box. After entering the box through the first air duct, the air does not flow through the bypass air valve 1 and directly enters the first evaporator 21 and the second evaporator 31, and then extends upward and passes through the first condenser 22; the air flowing through the second air duct extends upward after passing through the bypass air valve 1, and mixes with the air in the first air duct that passes through the first condenser 22. The air in the first air duct and the second air duct mix and pass through the second condenser 32 and are discharged from the box from the air supply port 7.

[0041] The blower 5 disposed on the top of the second condenser 32 can provide power for the wind entering the box.

[0042] In this embodiment, the control system 6 provided on the top of the box body can control the size of the bypass air valve 1 and adjust the size of the first air duct and the second air duct. The size of the bypass air valve 1 is adjusted according to the actual power used by the dehumidification unit. It is distributed on demand so that the first air duct obtains the best dehumidification capacity after passing through the first evaporator 21 and the second evaporator 31. After the first air duct passes through the first condenser 32 and merges with the second air duct, it passes through the second condenser 32, so that the mixed wind can obtain more condensing air volume after passing through the second condenser 32, reducing the condensing pressure of the refrigeration system, thereby improving the energy efficiency of the refrigeration system. In this embodiment, the air volume passing through the second evaporator 32 is separated from the air volume passing through the second condenser 32 through the first air duct and the second air duct, and distributed on demand through the bypass air valve 1, which ensures both the best dehumidification capacity and the best energy efficiency of the refrigeration system.

[0043] Heat pipes and cooling pipes are provided in the heat pipe system and the cooling system, respectively, and refrigerant is provided in both the heat pipe and cooling pipes. The refrigerant in the heat pipe system flows in the heat pipe by gravity or pump drive; the refrigerant in the cooling system flows in the cooling pipe by compressor 33. The bottom of the cooling pipe is connected to compressor 33, and an expansion valve 34 is provided on the pipe near compressor 33. Compressor 33 can compress the gaseous refrigerant, thereby increasing the temperature and pressure of the refrigerant so that it can release heat in the second condenser 32. Expansion valve 34 can control the flow rate and pressure of the refrigerant, and can save energy and reduce the pressure of high-pressure and high-temperature liquid refrigerant, forming a low-temperature and low-pressure refrigerant that enters the second evaporator 22, so that the second evaporator 22 can absorb heat and complete the refrigeration cycle. In other words, the refrigerant can absorb the cold energy of the second condenser 32 and transfer the cold energy to the second evaporator 31.

[0044] Reference Figure 2 , the arrow lines in the figure are the flow direction of the refrigerant, the dotted line is the flow direction of the refrigerant in the refrigeration system; the solid line is the flow of the refrigerant in the heat pipe system. The refrigerant releases heat to the environment in the first condenser 22, lowering the refrigerant's own temperature and increasing the temperature in the environment; the cooled refrigerant flows into the first evaporator 21 to absorb heat from the environment, increasing the refrigerant's own temperature and lowering the temperature in the environment. The heat pipe system can realize energy transfer, transferring the coldness of the first condenser 22 to the first evaporator 21. This process can achieve the effect of air precooling. The precooled airflow passes through the second evaporator 31 for cooling and dehumidification, and the temperature further drops. The airflow with a lowered temperature passes through the first condenser 22 and is affected by the refrigerant and its temperature rises.

[0045] The heat pipe system can recover the cooling energy of the air from the second evaporator 31 to pre-cool the air flow in the first air duct. Under the premise of maintaining the same dehumidification capacity, the configuration capacity of the refrigeration system can be reduced, the energy efficiency of the refrigeration system can be improved, and the energy saving effect can be enhanced.

[0046] The refrigeration system is a cooling system commonly used on the market.

[0047] In terms of structural layout, the heat recovery system condenser is set on the heat recovery system evaporator to form a sufficient height difference, which can further improve the heat recovery efficiency and energy-saving effect.

[0048] A refrigeration system and a heat pipe system are installed inside the dehumidifier unit. The refrigeration system can lower the air temperature and condense the moisture in the air. By adding a heat pipe system inside the dehumidifier unit, the heat pipe system can assist the refrigeration system and reduce the compressor configuration capacity of the refrigeration system.

[0049] The heat pipe system's first evaporator 21 and first condenser 22 form a structural height difference. This height difference leverages gravity to aid vapor rise and liquid reflux, reducing circulation resistance and energy loss, and improving the heat transfer efficiency of the heat pipe. This reduces or eliminates the need for additional mechanical equipment to propel liquid flow, lowering system energy consumption and further enhancing energy savings.

[0050] The dehumidifier unit is provided with a bypass ventilator 1. The air entering the dehumidifier unit is divided into a first air duct and a second air duct by the bypass ventilator 1. After passing through the bypass ventilator 1, the air in the first air duct passes through the first evaporator 21, the second evaporator 31, and the first condenser 22 in sequence, and then mixes with the air in the second air duct that has only passed through the bypass ventilator 1. The mixed air enters and passes through the second condenser 32, and is then sent out of the dehumidifier unit by the blower 5. The bypass ventilator 1 can adjust the ratio of the first air duct and the second air duct, so that the processed air volume passing through the first evaporator 21 and the second evaporator 31 is separated from the processed air volume passing through the second condenser 32. While ensuring the best dehumidification effect, more processed air volume can pass through the first condenser 21 and the second condenser 32, thereby reducing the condensing pressure of the refrigeration system and improving the energy efficiency of the refrigeration system.
