Description

A kind of central air-conditioning

Technical field

The utility model relates to a kind of central air-conditioning.

Background technology

Central air-conditioning is made up of water circulation system and air conditioning system, and water circulation system provides institute's chilling requirement or heat for air conditioning system, in order to offset refrigeration duty, the thermal load of indoor environment, thus realizes indoor refrigeration or system heat. The application of central air-conditioning in each field is general, and its technology is also well developed. Installing and maintenance work discovery by being engaged in central air-conditioning for a long time, also there are the following problems for current central air-conditioning:

1, each parts of central air-conditioning operationally can produce vibrating noise, for some special places, such as accurate production plant, Operation theatre, laboratory, the pharmaceutical production workshop that meets GMP, it is very harsh to the control of noise and fixed temperature and humidity, it is thus desirable to eliminate these noises as much as possible and keep the stability of temperature, humidity, such as the air-out noise of the indoor machine of installation on indoor furred ceiling, vibrating noise when outdoor machine runs, the noise produced when the new wind air processor that smallpox furred ceiling is installed runs.

2, central air-conditioning needs the joint to each pipe fitting to weld when mounted, retain in pipe body after welding or bond on tube wall, these welding slags, along with the long-time running of air-conditioning, come off along with refrigeration agent enters in compressor from tube wall, the normal operation of compressor are had an impact.

3, general furred ceiling that is indoor and corridor all requires high as much as possible, so that the interior space is spacious, return water pipe between indoor machine and outdoor machine is all arrange in furred ceiling, the rising pipe of each indoor machine is gathered by the pipeline that gathers arranged on the furred ceiling of corridor, gathering on the furred ceiling of general corridor manages horizontal layout, owing to adopting positive prime mode to carry out backwater between outdoor machine and indoor machine, install it is thus desirable to the rising pipe of indoor machine is presented gradient shape, the general requirement gradient reaches 3 ��, will obtain like this water pipe the other end to gather pipe height lower, make indoor, corridor furred ceiling is too low, as shown in Figure 1. in addition, if the gradient is inadequate when installing, recirculated water cannot normal reflow, then can bring very big leakage hidden trouble to the later stage.

4, the air outlet tube of indoor machine generally adopts common canvas duct to connect at present, after this kind of mode life-time service, canvas easily goes mouldy, condense, the phenomenon such as leak out, and air outlet tube cannot carry out large-sized stretching, often the size of cutting president when being install a bit or shorter, makes troubles to installation.

Practical novel content

The purpose of this utility model is just to provide a kind of central air-conditioning, and it at least can solve an above-mentioned problem.

For achieving the above object, the utility model have employed following technical scheme:

A kind of central air-conditioning, comprise water circulation system, air conditioning system, Controlling System and charge system, water circulation system comprises outdoor machine, air conditioning system comprises on new wind air processing machine and each indoor furred ceiling the indoor machine installed respectively, it is characterized in that: new wind air processing machine is arranged on furred ceiling by each 3rd suspension rod suspention shape, 3rd suspension rod comprises two the 3rd boom sections postponing up and down and arranging, is connected by pneumatic cushioning between two the 3rd boom sections.

The central air-conditioning provided in technique scheme, it can effectively subtract the noise of new wind air processing machine.
