Roof-top unit

Abstract

The invention provides a roof-top unit. The roof-top unit comprises a frame, a compressor and a fan, wherein the frame is formed by connecting profiles, an installation space is formed in the middle of the frame; the compressor is installed on a bottom plate of the frame or installed on a partition plate dividing the installation space into a first installation space body and a second installation space body; and the fan is located in the installation space and fixed to the top of the frame through an installation structure. According to the roof-top unit, when the fan and the compressor work at the same time, vibration of the fan / compressor is greatly attenuated when gradually transmitted to the position where the compressor / fan is located through the frame formed by connecting the multiple profiles, the vibration is not enough to cause intense resonance, through practical testing, the resonance phenomenon of the roof-top unit is not obvious, and the phenomena that noise caused by resonance is generated, and equipment is damaged due to resonance are avoided; and the compressor and the fan are reasonable in placement position, the evaporator size can be maximally increased in the original space, the heat exchange efficiency is improved, and the space utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of roof machines, in particular to a roof machine. Background technique [0002] The roof unit is a unitary unit of an all-air system, which can integrate the functions of cooling, heating, air supply, air purification and electric control. It is generally installed on the roof of a building, so it is called a roof unit. Because of the advantages of compact structure, wide cooling (heat) range, convenient debugging, convenient installation, and low investment and maintenance costs, the roof machine is widely used in metallurgy, chemical industry, electromechanical and other industries, as well as theaters, shopping malls, restaurants, bars, etc. and other occasions. [0003] The roof machine in the prior art generally includes a frame, an installation space is formed in the middle of the frame, and a partition is provided in the middle of the frame. The partition divides the installation space into left and...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome that the centrifugal fan and the compressor of the roof machine in the prior art are installed on the chassis at the same time. When the two work at the same time, resonance is easy to occur, which not only produces loud noise, but also easily damages the equipment. To overcome the technical defects of the centrifugal fan and the compressor, it is difficult to resonate when the centrifugal fan and the compressor work at the same time, so that it will not generate a lot of noise, and it will not easily damage the equipment.
