Description

Technical Field

[0001] This utility model relates to the field of air energy technology, specifically to a solar-assisted air energy unit. Background Technology

[0002] Solar energy is characterized by low pollution, environmental friendliness, and inexhaustible availability. Air source heat pumps, as energy-saving devices that utilize high-grade energy to transfer heat from low-grade heat sources to high-grade heat sources, can significantly reduce pollution from the combustion of fossil fuels. Both solar and air source energy are high-quality renewable energy sources with wide distribution, making them important energy sources that countries are vying to research and develop, and they possess significant advantages in future energy applications.

[0003] Air energy refers to the low-grade heat energy contained in the air, also known as air source energy. The law of conservation of energy tells us that energy cannot be created or destroyed; the heat energy in the air is generated by the air absorbing the energy emitted by sunlight. The higher the temperature, the more abundant the air energy.

[0004] Existing air source heat pumps utilize air energy for energy conversion and cannot increase the heat in the air through other means. The external environment has a significant impact on air energy; when the environment is cold, it reduces the heat in the air and decreases the conversion and utilization of air energy. Utility Model Content

[0005] The purpose of this invention is to provide a solar-assisted air source heat pump unit, which has the characteristic of continuing to operate normally in cold environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solar-assisted air source heat pump unit, comprising a mounting frame fixedly installed on the top of a housing, a solar collector fixedly installed on the inner side of the mounting frame, a support frame fixedly installed on the front side of the mounting frame, a solar panel fixedly installed on the top of the support frame, a battery box for storing batteries fixedly installed on the top of the housing, a ventilator fixedly installed on the top of the battery box, two electric heating wires for heating air provided on the inner side of the ventilator, a fan fixedly installed on the right side of the housing, an air source evaporator provided on the inner side of the housing, and an air outlet window fixedly installed at one end of the air source evaporator.

[0007] To facilitate energy conversion, in a preferred embodiment of this utility model of a solar-assisted air source heat pump unit, a compressor, a condenser, and a plate heat exchanger are fixedly installed on the inner side of the housing from right to left. A connecting pipe connects the air source evaporator to the compressor, a connecting pipe connects the compressor to the condenser, and a connecting pipe connects the condenser to the plate heat exchanger.

[0008] To facilitate heat exchange in the external water system, in a preferred embodiment of this solar-assisted air source heat pump unit, an inlet pipe and an outlet pipe are fixedly installed on the left side of the plate heat exchanger, with the inlet pipe located above the outlet pipe.

[0009] For ease of protection, in a preferred embodiment of this utility model of a solar-assisted air source heat pump unit, the front side of the housing is provided with a door to protect the compressor, condenser, and plate heat exchanger.

[0010] To facilitate air transport, in a preferred embodiment of this utility model of a solar-assisted air source heat pump unit, a connecting pipe is installed between the input end of the fan and the ventilation cylinder, a connecting pipe is installed between the output end of the fan and the input end of the solar collector, and a connecting pipe is installed between the output end of the solar collector and the input end of the air source evaporator.

[0011] To facilitate electric heating of air, in a preferred embodiment of this utility model of a solar-assisted air source heat pump unit, the solar panel is electrically connected to the battery inside the battery box, and the battery is electrically connected to the electric heating wire.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When the ambient temperature is high, the fan draws outside air directly into the solar collector through the ventilator, and then the air is transported to the air source evaporator, where the refrigerant absorbs heat and evaporates for energy conversion. When the ambient temperature is cold, the battery in the battery box supplies power to the electric heating wire, which heats the air passing through the ventilator. The fan then draws the hot air into the solar collector, which in turn transports it to the air source evaporator, where the refrigerant absorbs heat and evaporates for energy conversion. This allows for better energy conversion and utilization by the air source unit, enabling efficient energy conversion and utilization in different environments. Attached Figure Description
