Description
[technical field]
The utility model relates to a kind of air handling system, is specifically related to a kind of communication machine room that is used for and can makes its indoor phase-change constant-temperature system that reaches steady temperature.
[background technology]
At present, along with WorldCom's technology rapid development, a large amount of communication work machine rooms arise at the historic moment, owing to need carry out the reception and the emission of signal, reduce shielding, and it is to be based upon mountain top and unmanned field that many communication machine rooms are arranged.In general, the temperature of communications equipment room need be arranged in the comparatively constant scope, this is because electronic devices and components in use are easy to heating, the too high meeting of indoor temperature cause electronic devices and components rapidly aging, the service life of reduction equipment and serviceability, especially in weather comparatively hot season, the heating of electronic devices and components or damage can cause the fault of communication line.For addressing the above problem, most of communications equipment rooms adopt refrigeration air-conditioner to regulate indoor temperature, but there are three bigger defectives in this control temperature mode: the first constantly changes owing to temperature, must just can make communication machine room reach the constant temperature of setting by the long-term unlatching of air conditioner, can bring a large amount of power consumptions like this, waste of energy is serious.Simultaneously, because China's electric power resource is very deficient, especially in the season of sweltering heat, power-on time is very limited, is difficult to satisfy the demand of all trades and professions to electricity consumption, and the outage phenomenon often takes place, and relies on electric refrigeration very unreliable; It two is that general air-conditioning mostly adopts freon as cold-producing medium, can cause the pollution of atmosphere, does not meet environmental requirement; It three is when electric power breaks down, and the refrigerating and air-conditioning of machine room can't be worked, and it requires attendant's generating that is on the scene as early as possible, otherwise the too high equipment that will make of temperature can't work even damage.Particularly, often bother very much when the problems referred to above occurring at the unmanned maintenance machine room in outlying district and power failure area how.
[utility model content]
Technical problem to be solved in the utility model is, overcome the defective of above-mentioned prior art, providing a kind of is located in the communication machine room, utilize the characteristic of phase-change material, the day and night temperature difference according to different regions, between the mushy stage conversion of phase-change material, carry out the exchange of heat, thereby reach the constant temperature system of computer room temperature control.Be provided with the communication machine room of the utility model, both saved the consumption of electric energy, save daily operating cost again, and can guarantee the normal operation of equipment, also can play the effect of environmental protection.
For solving the problems of the technologies described above, technical scheme that the utility model proposes is:
A kind of phase-change constant-temperature system that is used for communication machine room, comprise supervising device, it is characterized in that: at described communication machine room madial wall or/and chamber top, be equipped with the phase change member that to carry out the solid-liquid conversion according to indoor temperature, described indoor air intake fan, the scavenger fan that is used for ventilation that also be provided with links to each other with supervising device.
Described phase change member is plane or the matrix that single plate body, tubular body are arranged in parallel or constitute more than at least one, all offers the containing cavity that can hold phase-change material on each member;
Wherein:
Described phase change member is the cuboid member, offers at least one in its member and can hold the containing cavity that phase-change material is inserted, and each containing cavity is vertically arranged along cuboid, offers intercommunicating pore between the adjacent containing cavity;
Described phase change member is the cuboid member, offers in its member and can hold the containing cavity that phase-change material is inserted, and described cuboid or following baseplane, or baseplane up and down, or whole outer surface is arranged with the above fin of a slice at least;
Described phase change member is a tubular element, is packaged with phase-change material in its pipe;
Described phase change member constitutes for the square member that becomes longitudinal and transverse arrangement and can rabbet or be sticked on the skeleton, offers in its member and can hold the containing cavity that phase-change material is inserted;
Described phase change member constitutes for the square member that becomes longitudinal and transverse arrangement and can rabbet or be sticked on the skeleton, offer in its member and can hold the containing cavity that phase-change material is inserted, described square or following baseplane, or baseplane up and down, or whole outer surface is the fin shape;
Described tube phase change external surface of structural member is arranged with the above square or circular fin of a slice at least;
