Problems solved by technology

[0004] However, both air-cooled heat pumps and cooling towers need to make the air flow quickly during the working process, and after the equipment is covered with a muffler cover, the air inside and outside the anechoic cover will be isolated, thereby hindering the flow of air and affecting air cooling. Normal operation of heat pump and cooling tower

Abstract

The invention relates to a noise reduction structure of an air-cooled heat pump and a cooling tower and a construction process of the structure, and relates to the field of noise reduction technology, which includes columns arranged around the equipment and fixed on the ground, and sound insulation boards arranged between the columns. The vertically arranged side walls of the sound insulation board are in contact with the uprights, and the lower end surface of the sound insulation board is in contact with the ground. The end surfaces of the sound insulation boards are penetrated with flow holes, and sound-absorbing louvers are arranged in the flow holes. The sound-absorbing louvers are used to realize the air flow on both sides of the sound-insulating board, and at the same time, the noise generated by the equipment is also reduced, so that the operation of the equipment will not be affected during the noise reduction process.

Description

technical field [0001] The invention relates to the technical field of noise reduction, in particular to a noise reduction structure of an air-cooled heat pump and a cooling tower and a construction process of the structure. Background technique [0002] Both air-cooled heat pumps and cooling towers are equipment used to exchange heat with air. They will generate a lot of noise during use, and the functional areas around the building have noise emission limits. Therefore, air-cooled heat pumps need to be and cooling tower for noise reduction treatment. [0003] In the existing noise reduction process, an anechoic cover is usually directly placed outside the equipment where the noise occurs, and the vibration of the air on the inner and outer sides of the anechoic cover is slowed down by the anechoic cover, so as to achieve the purpose of reducing noise. [0004] However, both air-cooled heat pumps and cooling towers need to make the air flow quickly during the working proce...
