Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning energy saving, and in particular to an energy-saving air conditioning purification system for clean rooms. Background Art

[0002] A clean room is a well-enclosed space where parameters such as air cleanliness, temperature, humidity, pressure, and noise can be controlled as needed. The clean room is equipped with an air conditioning purification system.

[0003] The existing air conditioning purification system includes an air conditioning unit, an air supply duct, an air inlet duct and an exhaust duct. One end of the air inlet duct is connected to the air conditioning unit, and the other end is connected to the atmosphere. The air conditioning unit is connected to the clean room through the air supply duct. One end of the exhaust duct is connected to the clean room, and the other end is connected to the atmosphere. When in use, the air conditioning unit draws air into the air conditioning unit through the air supply duct for heating or cooling, and then sends it into the clean room through the air supply duct. The air in the clean room is discharged into the atmosphere through the exhaust duct, thereby adjusting the temperature in the clean room.

[0004] When the air conditioning purification system is in use, the air in the clean room is directly discharged into the atmosphere, making it difficult to fully utilize the exhaust energy of the air conditioning purification system. Utility Model Content

[0005] In order to improve the energy utilization rate of air exhausted by an air conditioning purification system, the present application provides an energy-saving air conditioning purification system for a clean room.

[0006] The present application provides an energy-saving air conditioning purification system for a clean room, which adopts the following technical solution:

[0007] An energy-saving air conditioning purification system for a clean room comprises an air conditioning unit, an air inlet duct, an air supply duct, an exhaust duct and a heat exchange device, wherein the air inlet duct is located on the air conditioning unit and is connected to the air conditioning unit, one end of the exhaust duct is connected to the clean room, and the other end of the exhaust duct is connected to the atmosphere, and the heat exchange device is connected to the air inlet duct, and the heat exchange device is used to perform heat exchange between the air in the exhaust duct and the air in the air inlet duct.

[0008] By adopting the above technical solution, when the air-conditioning unit is heating, the air-conditioning unit passes the heat into the clean room through the air supply duct, the exhaust duct exhausts the air in the clean room, and the heat exchange device exchanges heat between the air in the exhaust duct and the air in the air inlet duct, thereby preheating or cooling the air in the air inlet duct, thereby improving the energy utilization rate of the air exhausted by the air conditioning purification system.

[0009] Optionally, the heat exchange device includes a heat exchange pipe, the heat exchange pipe is connected to the side wall of the exhaust pipe, the heat exchange pipe is spiral-shaped, and is sleeved on the air inlet pipe.

[0010] By adopting the above technical solution, when air enters the heat exchange pipe, the heat exchange pipe is spiral, which increases the contact area between the heat exchange pipe and the air inlet pipe, thereby improving the heat exchange efficiency between the air in the heat exchange pipe and the air in the air inlet pipe.

[0011] Optionally, the heat exchange device further includes a pneumatic regulating valve, and the pneumatic regulating valve is arranged at the air outlet of the heat exchange pipe.

[0012] By adopting the above technical solution, when air enters the heat exchange pipe, the air exhausted from the clean room accumulates in the heat exchange pipe for heat exchange. When the air pressure reaches the set value of the pneumatic regulating valve, the pneumatic regulating valve opens to discharge the air into the atmosphere. The pneumatic regulating valve prolongs the retention time of the hot air in the heat exchange pipe, thereby improving the heat exchange efficiency between the air in the heat exchange pipe and the air in the air inlet pipe.

[0013] Optionally, a baffle is provided in the heat exchange pipe, and the baffle is provided in multiple groups. The multiple groups of baffles are evenly arranged along the axial direction of the heat exchange pipe, and each group of baffles is provided with two baffles. The two baffles are inclined and arranged in a direction away from the flow direction of air in the heat exchange pipe and toward each other.

[0014] By adopting the above technical solution, when air enters the heat exchange pipe, the baffle slows down the flow rate of air in the heat exchange pipe and prolongs the time the air stays in the heat exchange pipe, thereby improving the heat exchange efficiency between the air in the heat exchange pipe and the air in the air inlet pipe.

[0015] Optionally, the heat exchange pipe is provided with fins, the fins are located on the side walls of the heat exchange pipe and fit with the air inlet pipe, and the fins are fixedly connected to the heat exchange pipe.

[0016] By adopting the above technical solution, when the air in the heat exchange pipe exchanges heat with the air in the air inlet pipe, the fins increase the contact area between the heat exchange pipe and the air inlet pipe, thereby further improving the heat exchange efficiency between the air in the heat exchange pipe and the air in the air inlet pipe.

[0017] Optionally, the fins are made of aluminum alloy material.

[0018] By adopting the above technical solution, the aluminum alloy material has good thermal conductivity and is cheap, thereby improving the heat exchange efficiency between the air in the heat exchange pipe and the air in the air inlet pipe.

[0019] Optionally, the heat exchange pipe is embedded in the side wall of the air inlet pipe.

[0020] By adopting the above technical solution, when heat exchange is performed, the heat exchange pipe is embedded in the side wall of the air inlet pipe, which increases the contact area between the heat exchange pipe and the air inlet pipe, thereby improving the heat exchange efficiency between the air in the heat exchange pipe and the air in the air inlet pipe.

[0021] Optionally, one end of the exhaust duct is connected to the clean room, and the other end is connected to the atmosphere; a first switch valve is provided at the end of the exhaust duct away from the clean room, and a second switch valve is provided between the end of the exhaust duct away from the clean room and the heat exchange duct; the heat exchange duct is connected to the side wall of the exhaust duct through the second switch valve; when heat exchange is required, the first switch valve is in a closed state, and the second switch valve is in an open state; when natural wind is exhausted, the first switch valve is in an open state, and the second switch valve is in a closed state.

[0022] By adopting the above technical solution, when natural wind is exhausted, the air in the clean room can be directly discharged into the atmosphere through the first switch valve.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a heat exchange pipe, the air entering the heat exchange pipe exchanges heat with the air in the air inlet pipe, so that the air in the air inlet pipe is preheated or cooled, thereby improving the energy utilization rate of the air discharged by the air conditioning purification system;

[0025] 2. By providing fins, the contact area between the heat exchange pipe and the air inlet pipe is increased, thereby improving the heat exchange efficiency between the air in the heat exchange pipe and the air in the air inlet pipe;

[0026] 3. By providing the baffle, the air flow rate in the heat exchange pipe is reduced, thereby extending the air retention time in the heat exchange pipe, thereby improving the heat exchange efficiency between the air in the heat exchange pipe and the air in the air inlet pipe.

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The present application embodiment discloses an energy-saving air conditioning purification system for a clean room.

The exhaust duct 4 discharges the air in the clean room into the heat exchange device 5. The heat exchange device 5 exchanges heat with the air in the exhaust duct 4 and the air in the air inlet duct 2, thereby preheating or cooling the air in the air inlet duct 2, thereby improving the energy utilization rate of the air exhausted by the air conditioning purification system.

[0036] The air supply duct 3 is in a circular tube shape, one end of the air supply duct 3 is connected to the air outlet of the air conditioning unit 1, and the other end of the air supply duct 3 is connected to the clean room.

[0037] The exhaust duct 4 is in a circular tube shape, one end of the exhaust duct 4 is connected to the clean room, and the other end is connected to the atmosphere.

One end of the heat exchange pipe 51 is connected to the exhaust pipe 4, and the other end of the heat exchange pipe 51 is connected to the pneumatic regulating valve 52.

[0039] During use, when air enters the heat exchange pipe 51, the pneumatic regulating valve 52 is in a closed state. When the air pressure in the heat exchange pipe 51 increases, the pneumatic regulating valve 52 opens and discharges the air into the atmosphere, thereby extending the retention time of the air in the heat exchange pipe 51.

[0040] Reference Figure 1 and Figure 2 The heat exchange pipe 51 is provided with a fin 511, which is in a rectangular sheet shape. There are two fins 511, which are respectively located on the side walls of the heat exchange pipe 51 and are in contact with the air inlet pipe 2.

The plurality of baffles 512 are evenly arranged along the extension direction of the heat exchange pipe 51, and each group is provided with two baffles. The two baffles 512 are inclinedly arranged in a direction away from the flow direction of the wind in the heat exchange pipe and toward each other.

[0042] When in use, the heat exchange pipe 51 is sleeved on the air inlet duct 2, and fins 511 are provided on the heat exchange pipe 51, which increases the contact area between the heat exchange pipe 51 and the air inlet duct 2, and improves the heat exchange efficiency between the air in the heat exchange pipe 51 and the air in the air inlet duct 2; the baffle 512 slows down the flow rate of the air in the heat exchange pipe 51, thereby extending the retention time of the air, thereby further improving the heat exchange efficiency between the air in the heat exchange pipe 51 and the air in the air inlet duct 2.
