Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to an intelligent modular air conditioning fresh air heat recovery system for ultra-low energy consumption buildings. Background Technology

[0002] Air conditioning is a device that regulates the temperature and humidity of the air. Its core principle is that refrigerant circulates between the compressor, condenser, throttling device, and evaporator, achieving indoor cooling or heating through heat absorption and release. It aims to create a comfortable and healthy indoor environment for people. In a conventional system, the refrigerant flows through the entire indoor heat exchanger, and the heat is released to the air in a one-way, one-time manner. The closer to the end of the coil, the lower the temperature of the refrigerant, and the smaller the temperature difference between it and the indoor air, resulting in a decrease in heat transfer efficiency. Although the refrigerant at the end has cooled down, it is still higher than the ambient temperature, and the residual heat it carries is wasted before passing through the throttling device. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent modular air conditioning fresh air heat recovery system for ultra-low energy consumption buildings to solve the above problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an intelligent combined air conditioning fresh air heat recovery system for ultra-low energy consumption buildings, comprising; Heat recovery copper pipes, internal heat exchanger, external heat exchanger, compressor, expansion valve; The two ends of the heat recovery copper pipe are connected to the two ends of the internal heat exchanger, which in turn are connected to the compressor and the expansion valve. The two ends of the external heat exchanger are also connected to the compressor and the expansion valve. During heating, the compressor releases high-temperature, high-pressure gas into the internal heat exchanger, which then releases heat to heat the room. When the high-temperature, high-pressure gas passes through the end of the internal heat exchanger, some of the gas, along with the heat from the heat recovery copper pipe itself, flows back into the heat recovery copper pipe and is then transported back to the connection between the internal heat exchanger and the compressor. During the heat release process, the heat recovery copper pipe absorbs some of the heat emitted by the internal heat exchanger. The heat absorbed by the heat recovery copper pipe, along with the high-temperature, high-pressure gas inside, is then transported back to the connection between the internal heat exchanger and the compressor, thus achieving heat circulation.

[0005] Preferably, the connection between the heat recovery copper pipe and the internal heat exchanger is equipped with a control valve B, which controls the flow direction and switching of gas and liquid inside the heat recovery copper pipe.

[0006] Preferably, the connection between the internal heat exchanger and the compressor has a control valve A, which controls the flow direction and switching of gas and liquid inside the heat recovery copper pipe.

[0007] Preferably, the outer side of the adsorption filter element A is fitted with an installation frame, and one end of the installation frame has a positioning bracket, which presses the heat recovery copper tube to prevent it from falling off.

[0008] Preferably, the outer side of the positioning frame has a filter cartridge shell, the inside of the filter cartridge shell has an adsorption filter element B, and the two sides of the filter cartridge shell have cover plates. The adsorption filter element B adsorbs dust and lint from the outside air, thereby improving indoor air quality.

[0009] Preferably, the mounting frame has an embedded adsorption filter element A and a filter screen. The adsorption filter element A adsorbs dust and lint from the outside air, improving indoor air quality. The filter screen then performs secondary filtration, further improving air quality.

[0010] Compared with the prior art, the beneficial effects of the present invention are: During heating, the compressor releases high-temperature, high-pressure gas into the internal heat exchanger, which then releases heat to heat the room. When the high-temperature, high-pressure gas passes through the end of the internal heat exchanger, some of the gas, along with the heat from the heat recovery copper pipe itself, flows back into the heat recovery copper pipe and is then transported again to the connection between the internal heat exchanger and the compressor. During the heat release process, the heat recovery copper pipe absorbs some of the heat dissipated by the internal heat exchanger. The heat absorbed by the heat recovery copper pipe, along with the high-temperature, high-pressure gas inside, is then transported back to the connection between the internal heat exchanger and the compressor, achieving heat circulation and significantly reducing heat loss. Furthermore, the internal heat exchanger at the air conditioner outlet heats up faster and more effectively. Attached Figure Description

When heating, the compressor 600 releases high-temperature and high-pressure gas into the interior of the internal heat exchanger 400, and then releases heat through the internal heat exchanger 400 to heat the room. When the high-temperature and high-pressure gas passes through the end section of the internal heat exchanger 400, some of the gas, along with the heat of the heat recovery copper pipe 200 itself, flows back into the interior of the heat recovery copper pipe 200, and is then transported again to the connection section between the internal heat exchanger 400 and the compressor 600.

Working principle: When heating, the compressor 600 releases high-temperature and high-pressure gas into the interior of the internal heat exchanger 400, which then releases heat to heat the room. When the high-temperature and high-pressure gas passes through the end section of the internal heat exchanger 400, some of the gas, along with the heat of the heat recovery copper pipe 200 itself, flows back into the interior of the heat recovery copper pipe 200.
