Description

Technical Field

[0001] The present invention relates to the technical field of heat pump air conditioners, and particularly to an electric heating and geothermal dual-condition heat pump air conditioner unit. Background Art

[0002] The electric heating and geothermal dual-condition heat pump air conditioner unit is an air conditioning device that integrates two working modes of electric heating and geothermal. The unit can flexibly switch between the electric heating mode and the geothermal mode according to the external environment and user needs, realizing efficient and energy-saving refrigeration and heating functions. In the electric heating mode, the unit uses electric heating tube elements for heating to provide auxiliary heat sources; in the geothermal mode, the unit extracts heat or cold from the underground heat source through ground source heat pump technology to achieve temperature regulation.

[0003] It is found in the use of existing electric heating and geothermal dual-condition heat pump air conditioner units that the electric heating tube elements are usually directly installed in the air duct and are prone to corrosion or failure during use. This is mainly because the electric heating tube elements are only activated for electric auxiliary heating in extremely cold weather and in the working mode of the heat pump air conditioner unit under the heating condition. When in the refrigeration mode, cold air in the air duct will generate condensed water, and the electric heating tube elements in the air duct are prone to accumulate condensed water, resulting in an increased probability of corrosion. Moreover, when in the refrigeration mode or when the electric heating tube elements do not need to work, since the electric heating tube elements are in the air duct, the electric heating tube elements will also increase the air duct resistance, resulting in a decrease in the indoor air flow velocity of the unit. To achieve the same air volume, the power consumption increases. Therefore, the current installation method of the electric heating tube elements has deficiencies. While having a relatively high self-failure rate, it also increases the air duct resistance and the power consumption under the same air volume. In view of the deficiencies of the prior art, the present invention provides an electric heating and geothermal dual-condition heat pump air conditioner unit to solve the above problems. Summary of the Invention

An auxiliary bracket is used to support the electric heating tube elements. Through the design of a flipping unit, the electric heating tube elements can be stored when not working. The flipping unit can drive the auxiliary bracket and the electric heating tube elements to flip and store as a whole. When the electric heating tube elements are flipped and stored, the electric heating tube elements can be stored in a non-air duct position when the electric auxiliary heating function is not required, avoiding the air resistance caused by being in the air duct position, reducing the accumulation of condensed water caused by the low temperature on the surface of the electric heating tube elements, reducing the corrosion probability of the electric heating tube elements, and extending the service life of the electric heating tube elements.

Detailed implementation manners

[0056] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention.

[0057] In the embodiment of the present application, by providing a heat pump air conditioner unit with dual working conditions of electric heating and geothermal energy, the problem that in the cooling mode, cold air in the air duct will generate condensate, and the electric heating tube elements in the air duct are prone to accumulate condensate, resulting in an increased probability of corrosion. Moreover, in the case of cooling or when the electric heating tube elements do not need to work, since the electric heating tube elements are in the air duct, the electric heating tube elements will also increase the air duct resistance, resulting in a decrease in the indoor air flow velocity of the unit. When achieving the same air volume, the power consumption increases. Therefore, there are deficiencies in the current installation method of the electric heating tube elements.

[0058] To better understand the above technical solution, the following will explain the above technical solution in detail in combination with the accompanying drawings of the specification and specific implementation manners.

[0059] Embodiment 1:

[0060] An embodiment of the present invention discloses a heat pump air conditioner unit with dual working conditions of electric heating and geothermal energy. As shown in the attached Figures 1-12 figures, it includes a ground source heat pump main system 20, an outdoor ground source heat exchange system 30, and an indoor terminal system 10;

[0061] The indoor terminal system 10 is a key component of the heat pump air conditioner unit with dual working conditions of electric heating and geothermal energy. The indoor terminal system 10 is responsible for effectively delivering the heat or cold generated by the ground source heat pump main system 20 to the indoor space.

[0062] The ground source heat pump main system 20 is set on the ground; the ground source heat pump main system 20 is responsible for converting the low-temperature heat energy or cold energy provided by the outdoor ground source heat exchange system 30 into high-temperature heat energy or cold energy through a heat pump cycle and delivering it to the indoor terminal system 10;

[0063] The outdoor ground source heat exchange system 30 is set underground and connected to the ground source heat pump main system 20; the outdoor ground source heat exchange system 30 is a bridge for the ground source heat pump system to exchange heat with the external environment. It uses the shallow geothermal resources on the earth's surface as a low-temperature heat source or cold source. The shallow geothermal resources on the earth's surface include soil, groundwater, surface water, etc., and transfer heat or cold to the ground source heat pump main system 20 through heat exchange pipelines;

[0064] The indoor terminal system 10 is set indoors and connected to the ground source heat pump main system 20. The indoor terminal system 10 includes an indoor main unit 1, a blower 2, an evaporator 3, an electric heating tube element 4, an auxiliary bracket 5, a flipping unit 6, and a protection unit 7.

[0065] The indoor main unit 1 is fixed on the wall; the indoor main unit 1 integrates a blower 2, an evaporator 3, an electric heating tube element 4, a flipping unit 6, and a protection unit 7 inside. The indoor main unit 1 is the main place for temperature regulation.

[0066] The blower 2 is arranged inside the indoor host 1; the blower 2 blows the air heated or cooled by the evaporator 3 or the electric heating pipe element 4 to quickly adjust the indoor temperature.

[0067] The evaporator 3 is arranged inside the indoor host 1 and is connected to the ground source heat pump host system 20 through a pipeline; the evaporator 3 is closely connected to the ground source heat pump host system 20 through a pipeline, and uses the refrigeration and heating principles of the ground source heat pump to achieve efficient heat exchange, which is the key component for the refrigeration and heating of the electric and geothermal dual-condition heat pump air conditioner unit.

[0068] The electric heating pipe element 4 is arranged inside the indoor host 1; the electric heating pipe element 4 is enabled in the cold season or when the geothermal condition heat pump air conditioner unit cannot meet the demand and additional heating is required, and generates heat through current heating to provide an auxiliary heat source to ensure the stability of the indoor temperature.

[0069] The auxiliary support 5 is arranged inside the indoor host 1 and is used to support the electric heating pipe element 4; the auxiliary support 5 is specially designed to support the electric heating pipe element 4 to ensure its stability and safety during operation. The auxiliary support 5 is connected to the flipping unit 6 through the rotating shaft 51. Therefore, the designs of the auxiliary support 5 and the flipping unit 6 facilitate the flipping and storage of the electric heating pipe element 4. When the electric heating pipe element 4 is flipped and stored, the electric heating pipe element 4 can be stored in a non-air duct position when the electric auxiliary heating function is not required, avoiding the air resistance caused by being in the air duct position, reducing the condensation water accumulation caused by the low temperature on the surface of the electric heating pipe element 4, reducing the corrosion probability of the electric heating pipe element 4, and extending the service life of the electric heating pipe element 4.

[0070] The flipping unit 6 is arranged inside the indoor host 1 and is used to control the flipping of the auxiliary support 5; the rotating shaft 51 is provided on the auxiliary support 5, and the flipping unit 6 includes:

[0071] The forward and reverse control motor 601 is arranged inside the indoor host 1;

[0072] The worm 602 is arranged at the output end of the forward and reverse control motor 601;

[0073] The worm gear 603 is arranged on the rotating shaft 51 and meshes with the worm 602.

[0074] The flipping unit 6 is composed of the forward and reverse control motor 601, the worm 602 and the worm gear 603. When the electric heating pipe element 4 does not need to work, the forward and reverse control motor 601 is started through the control panel. The forward and reverse control motor 601 drives the worm 602 to rotate. The worm 602 meshes with the worm gear 603. Therefore, the worm 602 drives the worm gear 603 to rotate. The worm gear 603 drives the rotating shaft 51 and the auxiliary support 5 to flip. The auxiliary support 5 further drives the electric heating pipe element 4 to move, and the electric heating pipe element 4 is stored in a non-air duct position.

[0075] The protection unit 7 is arranged inside the indoor host 1 and is used to protect the electric heating tube element 4. The protection unit 7 includes:

[0076] A guide rail seat 701, arranged inside the indoor host 1;

[0077] A sliding table 702, slidably connected to the guide rail seat 701, and a rack 7021 is arranged on the sliding table 702;

[0078] A protective cover 703, arranged on the sliding table 702;

[0079] A gear 704, arranged on the rotating shaft 51 and meshed with the rack 7021.

[0080] The protection unit 7 is composed of a guide rail seat 701, a sliding table 702, a protective cover 703 and a gear 704. The protective cover 703 slides on the guide rail seat 701 through the sliding table 702, and the gear 704 is meshed with the rack 7021. When the flipping unit 6 drives the electric heating tube element 4 to flip to the storage position, the protective cover 703 closes synchronously to cover the electric heating tube element 4, providing additional protection, further ensuring the stability of the electric heating tube element 4 and increasing the service life of the electric heating tube element 4;

[0081] When the flipping unit 6 drives the electric heating tube element 4 to flip, the rotation of the rotating shaft 51 will synchronously drive the gear 704 to rotate. The gear 704 drives the rack 7021 to move, the rack 7021 drives the sliding table 702 to move along the guide rail seat 701, and the sliding table 702 drives the protective cover 703 to move, using the protective cover 703 to further protect the electric heating tube element 4 and isolating the electric heating tube element 4 from the air duct.

[0082] A lubrication unit 8 is arranged inside the indoor host 1; the design of the lubrication unit 8 realizes automatic lubrication and maintenance of the key transmission components of the flipping unit 6 and the protection unit 7, reduces component wear and failure rates, and improves the stability of the unit;

[0083] The lubrication unit 8 includes:

[0084] A storage container 801, arranged on the indoor host 1; the storage container 801 is specifically used for storing lubricating oil to ensure sufficient supply of lubricating oil. A port 8011 is arranged on the storage container 801, and a cover is installed on the port 8011. The cover is installed or disassembled in a spiral manner, thereby facilitating the filling of lubricating oil inside the storage container 801.

[0085] The lubricating wheel 802 is rotatably connected to the storage container 801 and abuts against the worm 602. Lubricating oil is attached to the lubricating wheel 802. When the worm 602 rotates, the lubricating wheel 802 rotates accordingly, transferring the attached lubricating oil, so that the lubricating oil in the storage container 801 is evenly applied to the worm 602, achieving effective lubrication. During the rotation of the worm 602, the lubricating oil is synchronously driven onto the worm gear 603 to lubricate the transmission position.

[0086] The communication hole 803 is opened inside the storage container 801 and corresponds to the position of the lubricating wheel 802. The communication hole 803 ensures that the lubricating oil inside the storage container 801 can flow out smoothly and attach to the lubricating wheel 802.

[0087] A lubricating guide groove 5011 is provided on the rotating shaft 51. The lubricating guide groove 5011 is located between the worm gear 603 and the gear 704. A lubricating guide hole 7041 is provided on the gear 704;

[0088] Lubricating through grooves 7022 are provided on the sliding table 702 and the rack 7021.

[0089] During the rotation and transmission of the lubricating oil between the worm 602 and the worm gear 603, it is also transmitted through the lubricating guide groove 5011 on the rotating shaft 51. In cooperation with the lubricating guide hole 7041 on the gear 704, the lubricating oil can be transmitted to the gear 704 through the lubricating guide groove 5011 and the lubricating guide hole 7041, thereby achieving lubrication for the gear 704 and the rack 7021. Since lubricating through grooves 7022 are also provided on the sliding table 702 and the rack 7021, the lubricating oil also enters between the sliding table 702 and the guide rail base 701 through the lubricating through grooves 7022, further achieving lubrication for the transmission position between the sliding table 702 and the guide rail base 701. Therefore, the lubricating unit 8 lubricates the transmission positions of the flipping unit 6 and the protection unit 7, that is, lubricates each contact position of the worm 602, the worm gear 603, the gear 704, the sliding table 702 and the guide rail base 701, reducing the wear of the unit, improving the use stability of the unit, and extending the service life of the unit.

[0090] An installation bracket 101 is provided inside the indoor main unit 1. The installation bracket 101 is used to support the evaporator 3. The installation bracket 101 is specifically used to support the evaporator 3 to ensure the stability and safety of the evaporator 3 during the installation process.

[0091] Inside the indoor main unit 1, there is a carrier frame 102 for supporting the guide rail base 701. On the carrier frame 102, there is a motor bracket 103 for supporting the forward and reverse control motor 601, and there is also a column 104 for supporting the storage container 801 on the carrier frame 102. The carrier frame 102, the motor bracket 103, and the column 104 are respectively used to support the guide rail base 701, the forward and reverse control motor 601, and the storage container 801. This enhances the internal structural stability of the indoor main unit 1 and ensures the normal operation of all parts inside the indoor main unit 1.

[0092] On the indoor main unit 1, there is a front panel 105, and the front panel 105 is used for air outlet guiding. The design of the front panel 105 facilitates personnel to control the air direction through the control panel, optimizes the air flow path, and improves the air supply efficiency and comfort of the system.

[0093] When the electric heating and geothermal dual-mode heat pump air conditioning unit is in use, it includes the following steps:

[0094] Step 1, start the system: Start the ground source heat pump main unit system 20 through the control panel, and select the electric heating or geothermal working mode according to actual needs. The ground source heat pump main unit system 20 starts to operate, exchanges heat with the underground heat source through the outdoor ground source heat exchange system 30, and realizes refrigeration or heating through the cooperation of the indoor terminal system 10, the ground source heat pump main unit system 20, and the outdoor ground source heat exchange system 30.

[0095] Step 2, adjust the temperature: According to the operating state of the ground source heat pump main unit system 20, the blower 2 starts to blow air. After the air is heated or cooled by passing through the evaporator 3 or the electric heating tube element 4, it is sent into the room to realize rapid temperature adjustment. The user can set the indoor temperature through the control panel.

[0096] Step 3, storage of the electric heating tube element 4: When the electric heating tube element 4 does not need to work, start the flipping unit 6 through the control panel. The forward and reverse control motor 601 drives the worm 602 to rotate. The worm 602 meshes with the worm gear 603, drives the rotating shaft 51 and the auxiliary bracket 5 to flip, and stores the electric heating tube element 4 in a non-air duct position. At the same time, the gear 704 of the protection unit 7 meshes with the rack 7021, driving the protective cover 703 to close and cover the electric heating tube element 4.

[0097] Step 4, lubrication and maintenance: Regularly check the lubricating oil level in the storage container 801 to ensure sufficient supply of lubricating oil. When it is found that the lubricating oil is insufficient, open the cover on the port 8011 and add an appropriate amount of lubricating oil into the storage container 801.
