Description

Technical Field

[0001] This utility model relates to the field of air source heat pump energy-saving technology, and in particular to an air source heat pump unit energy-saving system. Background Technology

[0002] An air source heat pump is an energy-saving device that uses high-grade energy to move heat from a low-grade heat source (air) to a high-grade heat source. It is a type of heat pump. As the name suggests, a heat pump, like a pump, can convert low-grade heat energy (such as the heat contained in air, soil, and water) that cannot be directly used into usable high-grade heat energy, thereby achieving the goal of saving some high-grade energy (such as coal, natural gas, oil, and electricity).

[0003] Air source heat pump units utilize the heat exchange between the equipment and the atmosphere to provide cooling in summer and heating in winter. The efficiency of the unit is directly related to the ambient temperature.

[0004] Current air source heat pump units typically utilize the heat from outdoor air, and their performance varies with changes in outdoor climate. Sometimes, the efficiency of air source heat pump units is not high. In areas of northern my country where outdoor air temperatures are low, auxiliary heaters are required due to insufficient heating from heat pumps in winter, resulting in poor energy consumption reduction. Utility Model Content

[0012] Furthermore, it also includes: longitudinal beams and columns. There are two longitudinal beams, which are symmetrically fixedly connected between the middle of the front and rear ends of the crossbeam and the middle of the front and rear sides of the inner wall of the U-shaped bracket.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By using exhaust fans and ventilation ducts, air from the underground garage is blown directly towards the air inlet of the air source heat pump through several exhaust vents. Since the air exhausted from the garage is cooler than the ambient temperature in summer and warmer in winter, the efficiency of the air source heat pump unit can be improved. At the same time, the high air velocity of the exhaust fans can increase the convective heat exchange with the air source heat pump unit, further improving the unit's efficiency and thus reducing energy consumption. The entire device can reduce energy consumption and has a good effect when used in northern my country.

[0017] 2. The solar panel components with tracking function can make full use of solar energy to power all electrical appliances in the system except for the air source heat pump. These electrical appliances do not need to be connected to the mains power to ensure the operation of the entire system, further saving some high-grade energy. Attached Figure Description

An exhaust fan 3 is installed inside the ventilation duct 2, and the exhaust fan 3 is located on the side of the ventilation duct 2 near the air outlet. Several exhaust vents 4 are provided at the bottom of the ventilation duct 2 in the underground garage section.

[0026] In this embodiment, the air source heat pump unit energy-saving system further includes: a solar panel assembly 6 with a light-tracking function, an inverter 7, and a battery 8. Several sets of solar panel assemblies 6 are provided, and the several sets of solar panel assemblies 6 are evenly fixed on the roof of the house 1.

[0027] In this embodiment, the solar panel assembly 6 includes: a U-shaped bracket 601, a rotating bracket 602, a rotating shaft 603, a solar panel mounting plate 604, and a solar panel 605.

There are four columns 618, whose top ends are fixedly connected to the middle of the bottom ends of the two longitudinal beams 617 and the middle of the left and right sides of the bottom end of the crossbeam 606, respectively. The bottom ends of the four columns 618 are fixedly connected to the top output end of the solar panel rotary assembly.

[0030] In this embodiment, the solar panel rotating assembly includes: a rotating disk 619, a base 620, a rotating gear 621, a connecting shaft 622, a servo motor 623, and a motor bracket 624. The base 620 has a rotating groove at its top, and the rotating disk 619 is rotatably connected within this groove. Four columns 618 are evenly fixedly connected to the top of the rotating disk 619. The bottom of the rotating disk 619 has an internal tooth groove, which the rotating gear 621 meshes with. The bottom of the rotating gear 621 is fixedly connected to the connecting shaft 622.

The bottom of the connecting shaft 622 is fixedly connected to the servo motor 623. The servo motor 623 is fixedly installed on the top of the inner groove through the motor bracket 624. When it is necessary to adjust the rotation angle of the solar panel 605, the servo motor 622 drives the rotation gear 621 to rotate, which can drive the turntable 619 and the solar panel 605 installed on its top to rotate to a suitable angle.

[0031] In this embodiment, the solar panel assembly 6 further includes a controller 625 and a light sensor 626. The controller 625 is fixedly installed on one side of the top of the recess, and the light sensor 626 is fixedly installed on one side of the front of the U-shaped bracket 601. The light sensor 626 is electrically connected to the controller 625. The battery 8 is electrically connected to several servo motors 610, several servo motors 623, several controllers 625, several light sensors 626, and several exhaust fans 3. The controllers 625 are electrically connected to the servo motors 610 and servo motors 623 in the same solar panel assembly 6. The several solar panels 605 in the entire system generate electricity using solar energy and transmit the electricity to the battery 8 through the inverter 7. The battery 8 supplies power to the several servo motors 610, several servo motors 623, several controllers 625, several light sensors 626, and several exhaust fans 3.

[0032] Because underground parking garages are located below ground level and protected by the surrounding soil, their temperature is relatively stable and unaffected by external weather changes. Furthermore, due to their contact with the soil, the walls and floors of underground parking garages have relatively lower temperatures in summer and relatively higher temperatures in winter. Compared to outdoor air temperatures, the exhaust air temperature in underground parking garages is relatively lower in summer and relatively higher in winter.

[0033] When the entire system is working, several solar panels 605 generate electricity using solar energy and transmit the electricity to batteries 8 through inverters 7. Batteries 8 supply power to several exhaust fans 3. The exhaust fans 3 discharge the air from the underground garage through several ventilation pipes 2 to the air inlets of several air source heat pumps 5. The air discharged from the garage is cooler than the air temperature in summer and warmer in winter, which can improve the efficiency of the air source heat pump units. At the same time, the air velocity discharged by the exhaust fans is relatively high, which can increase the convective heat exchange with the air source heat pump units, further improve the efficiency of the units, and thus reduce energy consumption. The entire system consists of several solar panels 605 that generate electricity using solar energy and transmit the electricity to the battery 8 via the inverter 7. The battery 8 also supplies power to several servo motors 610, servo motors 623, controllers 625, and light sensors 626. The light sensors 626 transmit light intensity information to their corresponding controllers 625, which in turn control the servo motors 610 and 623 to adjust the solar panels 605 to the optimal angle for receiving sunlight, thereby making full use of solar energy.
