Description

Fan filter unit with refrigeration function

Technical Field

The utility model relates to a mechanical equipment technical field, in particular to take fan filter unit of refrigeration function.

Background

At present, in order to maintain the required parameters such as temperature, humidity, wind speed, pressure and cleanliness in the clean room, the most common method is to continuously feed a certain amount of treated air into the clean room to eliminate various kinds of heat and humidity interference and dust pollution inside and outside the clean room.

In addition, the heating conditions of the process equipment are different with different production processes, and some process equipment is high-heating equipment and needs more cooling loads to offset. In addition, some clean rooms have no space for installing special refrigeration equipment because the space is limited during the actual installation process. Therefore, it is necessary to design a fan filter unit with a cooling function to satisfy the requirement of cooling to reduce the indoor temperature while purifying the indoor air.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model discloses a take fan filter unit of refrigeration function.

The utility model discloses the technical scheme who adopts as follows:

a fan filter unit with a refrigeration function comprises an upper layer box body and a lower layer box body; the top of the upper layer box body is provided with an air inlet, and the bottom of the lower layer box body is provided with an air outlet; a primary filter and a fan are arranged in the upper-layer box body; the primary filter is arranged at an air inlet of the upper-layer box body; an air-cooled cooler and a high-efficiency filter are arranged in the lower-layer box body; the inlet of the fan is communicated with the outlet of the primary filter, and the outlet of the fan is communicated with the inlet of the air-cooled cooler; and the outlet of the air-cooled cooler is connected with the inlet of the high-efficiency filter.

The method is further characterized in that: the air-cooled cooler comprises a shell and a tube bundle; the tube bundle is mounted within the shell; the tube bundle is attached with metal spirally wound radiating fins; the tube bundle comprises a refrigerant inlet and a refrigerant outlet, and the refrigerant inlet and the refrigerant outlet are both communicated with a compressor; the compressor discharges a refrigerant.

The method is further characterized in that: the volume of the upper layer box body is smaller than that of the lower layer box body; the area of the air inlet is smaller than that of the air outlet.

The utility model has the advantages as follows:

the air or wind is sucked by the fan in the fan filter unit, the absorbed air or wind passes through the filter screen of the primary filter and the filter screen of the high-efficiency filter to filter large-particle dust particles in the air, and finally the fresh air is uniformly delivered to the clean room at the air speed of 0.45m/s +/-10%.

The air-cooled cooler takes air as a cooling medium, and takes away cold energy by the temperature drop of the air. Specifically, liquid refrigerant enters the air-cooled cooler from the refrigerant inlet, and when air or wind is introduced into the lower-layer box body from the primary filter through the fan, the air or wind passes over the radiating fins of the air-cooled cooler in a head-on manner, so that the cold energy emitted by the refrigerant in the tube bundle is absorbed, the refrigerant is gasified, and the cold air or cold wind can be emitted into the clean room to achieve the refrigerating effect in the clean room.

The utility model discloses can filter air again when can reaching the refrigeration effect.

Detailed Description

The foregoing and other features, aspects and utilities of the present invention will be apparent from the following detailed description of the embodiments, which is to be read in connection with the accompanying drawings. Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are simply directions with reference to the drawings. Therefore, the directional terminology used is for the purpose of description and is not intended to be limiting, and moreover, like reference numerals will be used to refer to like elements throughout.

The following describes a specific embodiment of the present embodiment with reference to the drawings.

Fig. 1 is a front view of the present invention, fig. 2 is a side view of the present invention, and fig. 3 is a top view of the present invention. With reference to fig. 1, 2 and 3, a fan filter unit with a refrigeration function includes an upper case 1 and a lower case 2. An air inlet is formed in the top of the upper layer box body 1, and an air outlet is formed in the bottom of the lower layer box body 2. The inside installation primary filter 3 and fan 4 of upper box 1. The primary filter 3 is arranged at the air inlet of the upper-layer box body 1. An air-cooled cooler 5 and a high-efficiency filter 6 are installed inside the lower casing 2. The inlet of the fan 4 is communicated with the outlet of the primary filter 3, the outlet of the fan 4 is communicated with the inlet of the air-cooled cooler 5, and the outlet of the air-cooled cooler 5 is connected with the inlet of the high-efficiency filter 6.

The air-cooled cooler 5 includes a shell and a tube bundle. The tube bundle is mounted within the shell. The tube bundle is attached with metal spiral winding radiating fins. The tube bundle comprises a refrigerant inlet and a refrigerant outlet both communicating with the compressor 7. The compressor 7 discharges the refrigerant.

The volume of the upper layer box body 1 is smaller than that of the lower layer box body 2. The area of the air inlet is smaller than that of the air outlet.

The working principle of the utility model is as follows:

the fan 4 in the fan filter unit is used for sucking air or wind, the absorbed air or wind passes through the filter screen of the primary filter 3 and the filter screen of the high-efficiency filter 6 to filter large-particle dust particles in the air, and finally the fresh air is uniformly sent to the clean room at the wind speed of 0.45m/s +/-10%.

The air-cooled cooler 5 takes air as a cooling medium, and takes cooling energy away by the temperature drop of the air. Specifically, liquid refrigerant enters the air-cooled cooler 5 from a refrigerant inlet, and when air or wind is introduced into the lower-layer box body 2 from the primary filter 3 through the fan 4, the air or wind passes over the radiating fins of the air-cooled cooler 5 in a head-on manner, so that the cold energy emitted by the refrigerant in the tube bundle is absorbed, the refrigerant is gasified, and the cold air or cold wind can be emitted into the clean room to achieve the refrigerating effect in the clean room.
