Description

Turbo cooling supercharged heating CFC-free air conditioning unit

The utility model belongs to the dual technical field of an air conditioner and a turbocharged internal combustion engine, and is particularly suitable for automobiles.

Since the advent of automobile air conditioners, Freon was mainly used as the refrigerant in the early stage. Due to its strong destructive effect on the ozone layer, it is being phased out and replaced by HFC-134a. But HFC-134a is not only expensive, but more importantly, it is a greenhouse gas. At the third meeting of the parties to the United Nations Framework Treaty on Climate Change held in Kyoto, Japan in December 1997, HFCs were among the six gases to limit emissions. In order to establish an action mechanism for the "Kyoto Protocol", the fourth, fifth and sixth meetings of the United Nations Climate Change Framework were held successively in Buenos Aires in 1998, Bonn in 1999, and The Hague in November 2000. Conference of the Parties, seeking to reach concrete agreements. Although the Hague negotiations failed to achieve results, the participating countries decided to resume the meeting in early 2001, showing their determination to reduce greenhouse gas emissions to prevent global warming. It can be seen that it is not a good way to substitute HFC-134a for Freon in automobile air conditioners, and the traditional automobile air conditioners are facing a crisis.

The purpose of this utility model is to provide a fluorine-free air-conditioning device for turbo refrigeration, supercharged heating, which can effectively prevent and avoid the damage of the ozone layer caused by the discharge of Freon, and can also effectively prevent and avoid the discharge of HFC-134a. The greenhouse effect can also significantly reduce the emissions of automobile internal combustion engines.

The fluorine-free air-conditioning device for turbo refrigeration, supercharging and heating of the utility model includes two turbochargers, heat exchangers, fans, valves and connecting pipelines respectively composed of a turbine and a compressor, and is characterized in that:

A) The turbine inlet end of a turbocharger is connected to the exhaust manifold of the internal combustion engine; the inlet and outlet ends of the compressor are provided with a three-way pipe; Connected to the gas outlet on the right side of the heat exchanger; one end of the three-way pipe at the outlet of the compressor is connected to the valve to open to the atmosphere, and the other end is connected to the inlet port on the left side of the heat exchanger through the valve;

B) The turbine inlet port of the other turbocharger is open to the atmosphere, and the outlet port is connected to the air inlet port on the left side of the heat exchanger through a valve and the outlet pipe of the air compressor of the previous turbocharger; The inlet end of the compressor is open to the atmosphere, and the outlet end is connected to the intake pipe of the internal combustion engine through a valve and a nozzle;

C) The air outlet end on the right side of the heat exchanger is also provided with a branch pipeline connected with the inclined pipe of the intake pipe of the internal combustion engine through a valve; a two-position valve is provided at the intersection of the intake pipe of the internal combustion engine and the inclined pipe;

D) The heat exchanger is provided with channels for two airflows which are perpendicular to each other and do not mix with each other; the upper and lower sides of the heat exchanger are respectively provided with an air inlet pipeline and an air outlet pipeline, and A suction fan is arranged in the pipeline, and the air outlet pipeline is respectively connected with valve-controlled air-conditioning, heating and a pipeline leading to the atmosphere.

The utility model has the advantages that as an air conditioner, it does not use Freon that destroys the ozone layer of the atmosphere, nor does it use other chemical substitutes in the HFC-134a domain that belong to the greenhouse gas, and only uses air, thereby completely meeting the requirements of environmental protection , and easy to use and manage, under heating and non-cooling heating conditions, not only the power of the internal combustion engine does not decrease, but also the emission of internal combustion engines is significantly reduced. Since the exhaust gas energy of the internal combustion engine is used as the power source, it is suitable for occasions powered by the internal combustion engine, especially automobiles.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in accompanying drawing 1, the turbocharged heating fluorine-free air conditioner of the present utility model comprises two turbochargers A, B, heat exchanger 3, fan that are made of turbine 1,8 and compressor 2,9 12. Valve and connecting pipeline. The inlet end of the turbine 1 of the turbocharger A is connected to the exhaust manifold of the internal combustion engine, and the inlet and outlet ends of the compressor 2 are provided with three-way pipes: one end of the three-way pipe at the inlet end is connected with the valve 4-1 to open to the atmosphere, and the other end is connected to the atmosphere. It is connected to the gas outlet on the right side of the heat exchanger 3 through the valve 5-2. One end of the tee pipe at the outlet end of the compressor 2 is connected to the valve 5-3 to lead to the atmosphere, and one end is connected to the inlet port on the left side of the heat exchanger 3 through the valve 4-2. The inlet of the turbine 8 of the turbocharger B is open to the atmosphere, and the outlet port is merged with the outlet pipe of the compressor 2 of the previous turbocharger A through the valve 5-1, and is connected to the left side of the heat exchanger 3 air intake. The inlet end of its air compressor 9 leads to the atmosphere, and in the air compressor 9 inlet pipes, the controllable pre-rotating vane (not shown) can be adorned. The outlet end is connected with the intake pipe 7 of the internal combustion engine through the valve 5-5 and the nozzle 6. The outlet end on the right side of the heat exchanger 3 is also provided with a branch pipeline connected with the inclined pipe 10 of the intake pipe 7 of the internal combustion engine through the valve 4-3, and a two-position valve is provided at the intersection of the intake pipe 7 of the internal combustion engine and the inclined pipe 10 11. The heat exchanger 3 is provided with a passage for two streams of air that are perpendicular to each other and do not mix with each other. The passage is a flip-fin air-to-air cooler structure. The upper and lower sides of the heat exchanger 3 are respectively equipped with an air inlet pipeline and an air outlet pipeline, and an air suction fan 12 is installed in the air inlet pipeline, and a valve 4- 4. Air-conditioning and heating pipelines controlled by 5-4 and pipelines leading to the atmosphere controlled by valve 4-5.

An air cleaner (not shown) is installed on the pipeline before the inlet of the compressor 9 and the inlet of the compressor 2 through the inlet of the valve 4-1 and on the pipeline before the inlet of the turbine 8.

Its working principle: the high-temperature exhaust gas discharged from the exhaust manifold of the internal combustion engine enters the turbine 1 of the turbocharger A at a pressure PT, expands and discharges after doing work, and the power generated by the turbine 1 drives the compressor 2 to rotate at a high speed. When cooling, valves 5-1, 2, 3, 4, and 5 are all opened, valves 4-1, 2, 3, 4, and 5 are all closed, and valve 11 is located at the vertical position shown in the figure. The outlet is at atmospheric pressure Pa, and a low-pressure area is formed at the inlet end of the compressor 2, so that the turbine 8 of the turbocharger B sucks air with a pressure of Pa from the atmosphere, expands and cools down to form a cold air flow through the heat exchanger 3 and flows to the turbine The inlet end of the compressor 2 of the supercharger A is discharged to the atmosphere through the valve 5-3 after being pressurized by the compressor 2. The air sucked from the atmosphere is blown to the heat exchanger 3 by the fan 12, and flows through in a direction perpendicular to the cold air flow without mixing with each other. Part of the heat is taken away by the cold air flow and then flows into the air conditioning pipeline through the valve 5-4 for supply. The compartment cools down. The turbine 8 of the turbocharger B sends power to drive the compressor 9 to inhale air from the atmosphere. After being pressurized by the compressor 9, it flows into the intake pipe 7 of the internal combustion engine through the valve 5-5 and the nozzle 6. Due to the ejection effect of this airflow , can increase the air flow of the internal combustion engine (the air flow direction under the cooling condition is shown by the solid arrow in the accompanying drawing 1). When heating, valves 4-1, 2, 3, and 4 are all open, valves 5-1, 2, 3, and 4 are all closed, and valve 11 is located at the level shown in the figure. Since valve 5-1 is closed, turbine 8 There is no air-flow passing in the middle, the valve 5-5 is closed, and there is no air-flow passing in the compressor 9, so the turbocharger B does not have any action, and becomes a falsehood. At this time, the compressor 2 in the turbocharger A driven by the turbine 1 and rotating at a high speed sucks in air from the atmosphere through the valve 4-1, and the air is boosted by the compressor 2 and becomes a hot air flow, which flows into the air through the valve 4-2. The heat exchanger 3 enters the inclined pipe 10 through the valve 4-3 after flowing out and flows into the internal combustion engine. Because the valve 11 is in a horizontal position, the air flow will not flow back to the atmosphere through the intake pipe 7. Now, the air flow blown by the fan 12 through the heat exchanger 3 obtains heat from the above-mentioned hot air flow and becomes heating air. In non-cooling and heating conditions, the difference from heating conditions is only that valve 4-4 is closed and valve 4-5 is opened at this time, and the warm air flowing out of heat exchanger 3 flows into the atmosphere through valve 4-5 , and other aspects are the same as the heating condition (the airflow direction under the heating condition and the non-refrigerating and heating condition is shown by the dotted arrow in the accompanying drawing 1). In fact, valves 4-4 and 4-5, valves 5-1 and 4-3, valves 5-2 and 4-1, valves 5-3 and 4-2 can be made into two-position valves respectively, and electric control or Mechanical linkage is controlled.

In the case of heating and non-cooling and heating conditions, the internal combustion engine becomes a supercharged intercooled internal combustion engine at this time, and the internal combustion engine can be adjusted without reducing the output power of the engine to greatly reduce the pollution of the internal combustion engine.

In order to be suitable for cooling in hot and dry areas, the device is also provided with a sprinkler 14 between the outlet pipeline of the turbine 8 of the turbocharger B and the valve 5-1. This sprinkler 14 (seeing Fig. 2, Fig. 3) is made of water spray pipe section, radial pipe, annular pipe, nozzle, water pipe, water valve and water container. In the middle section of the water spray pipe section 14-3, there are four identical meridional small holes evenly distributed along the circumference, and the same radial pipe 14-2 is welded on each small hole, and the outer end of each meridian pipe is welded with the ring pipe 14-1 And communicate, be welded with nozzle 14-4 on the annular pipe, nozzle is communicated with water pipe, water valve and water container, and the water surface height in the water container should be lower than the lowest point of annular pipe 14-1. The effect of the water sprayer 14 is to spray water to the cold airflow flowing to the left side of the heat exchanger 3, and the water vaporization makes the cold airflow further cool down.
