Technical Field
[0001] The utility model relates to the technical field of ground source heat pump units, in particular to an anti-icing device for ground source heat pump units. Background Art
[0002] A ground source heat pump unit is a device that uses water circulating in public pipelines, water drawn from wells, lakes or rivers, or water circulating in underground coils as a cold (heat) source to produce cold (hot) air or cold (hot) water. It includes a user-side heat exchange device, a compressor, and a heat source-side heat exchange device, and has single refrigeration or refrigeration and heating functions. Ground source heat pump units are divided into cold and hot air type water source heat pump units and cold and hot water type water source heat pump units according to the form of the user-side heat exchange device, and are divided into water ring water source heat pump units, groundwater water source heat pump units and underground loop water source heat pump units according to the type of cold (heat) source. People usually call the air-conditioning system using the former a water ring heat pump air-conditioning system, and the air-conditioning system using the latter two as a ground source heat pump air-conditioning system.
[0003] In actual use, the existing ground-source heat pump units will have the water temperature inside drop to zero degrees or below zero due to the heat absorption of Freon, which may cause ice to form inside the pipes, damaging the pipes. In addition, because the temperature of the outer wall of the pipe is different from the internal water temperature, water droplets will form on its surface, causing damage to surrounding parts, thereby affecting the service life of some parts. Utility Model Content
[0004] The purpose of the present utility model is to provide an anti-icing device for a ground source heat pump unit, so as to solve the problem in the above background technology that the ground source heat pump unit will reduce its internal water temperature due to the heat absorption effect of Freon during use, which may cause the water inside the pipe to freeze, and the temperature difference between the inside and outside of the pipe will produce water droplets, which will cause damage to surrounding parts. In order to achieve the above purpose, the present utility model provides the following technical solutions: an anti-icing device for a ground source heat pump unit, including a bracket, a heating component is arranged on the outside of the bracket, and the heating component includes a heating box, the heating box is fixedly connected to the middle part of the outer wall of the bracket, an air inlet 1 is opened in the middle part of the outer wall of the heating box, a support frame 1 is fixedly connected to the inside of the heating box, and a heater is fixedly connected to the inner wall of the support frame 1.
[0005] Further preferably, an air outlet is provided inside the bracket, an electric fan is fixedly connected inside the air outlet, a support frame 2 is fixedly connected to the bottom of the heating box, and a threaded hole is provided on the front of the bracket. By installing a heating component, when in use, the airflow of the geothermal heat pump unit can be heated by cooperation between components such as the heater and the electric fan, so that the water flow on the pipe surface and inside the pipe can fully absorb the heat in the airflow, thereby preventing the water flow inside the pipe from freezing, avoiding the water flow inside the pipe from freezing due to the heat absorption effect of Freon during the use of the geothermal heat pump unit, and generating a large number of water droplets on the pipe surface, thereby affecting the service life of the parts of the geothermal heat pump unit, which is beneficial to improving the practicality of the device.
[0006] Further preferably, a circulation component is arranged in front of the bracket, and the circulation component includes a circulation frame, and the circulation frame is fixedly connected to the front side of the bracket, and a second air outlet is opened in the middle of the inner wall of the circulation frame.
[0007] Further preferably, a protective net is fixedly connected to the inside of the air outlet two, a guide pipe is fixedly connected to the middle of the outer wall of the circulation frame, a circulation pipe one is fixedly connected to the outer side of the guide pipe, and a support plate is fixedly connected to the bottom of the front side of the circulation frame. By installing the circulation component, during the heat transmission process, there is still unabsorbed heat in the airflow. Through the cooperation between the circulation pipe one, the blower and the circulation pipe two components, the airflow without absorbed heat can be circulated and then absorbed again, thereby avoiding the situation that during the heating process, the heat contained in the airflow cannot be fully absorbed by the pipeline of the ground source heat pump unit, resulting in heat waste in the air, thereby affecting the subsequent work progress, which is conducive to improving the use effect of the device.
[0008] Further preferably, a blower is fixedly connected to the bottom of the support plate, a circulation pipe 2 is fixedly connected to one side of the blower, and a bolt is threadedly connected to the inner cavity of the threaded hole.
[0009] Further preferably, the guide pipe is connected to the second air outlet, the circulation pipe one is fixedly connected to the other side of the top of the blower, and the circulation pipe two is fixedly connected to the bottom of the front side of the heating box. The bolt passes through the circulation frame. By installing the circulation component, during use, the heating area of the device can be changed according to the size of the geothermal heat pump unit through the cooperation between components such as bolts and threaded holes, thereby avoiding the large size of the geothermal heat pump unit during use, which makes the device unable to heat the pipeline of the geothermal heat pump unit, thereby affecting the subsequent work process, which is conducive to improving the practicality of the device.

Through the cooperation between the circulation pipe 1, the blower and the circulation pipe 2, the airflow that has not absorbed the heat can be circulated and then absorbed again, so as to avoid that the heat contained in the airflow cannot be fully absorbed by the pipeline of the ground source heat pump unit during the heating process, resulting in heat waste in the air, thereby affecting the subsequent work process, which is conducive to improving the use effect of the device;
[0013] In the utility model, by installing the circulation component, during use, through the cooperation between components such as bolts and threaded holes, the heating area of the device can be changed according to the size of the ground source heat pump unit, thereby avoiding the ground source heat pump unit being large in size during use, resulting in the device being unable to heat the ground source heat pump unit pipeline, thereby affecting the subsequent work process, which is beneficial to improving the practicality of the device.

When the temperature of the heater 204 rises to a certain level, the electric fan 206 is started. When the electric fan 206 is started, the airflow enters the heating box 201 from the air inlet 202, and then passes through the heater 204, so that the hot airflow from the electric fan 206 supplies heat to the ground source heat pump unit, so that the pipes of the ground source heat pump unit and the water flow inside it can fully absorb heat.

When the temperature of the heater 204 rises to a certain level, the electric fan 206 is started.
