Description
Technical field
The present invention relates to the multi-gang air-conditioner technical field, relate in particular to a kind of method of wind pipe type indoor set and control wind pipe type indoor set capacity.
Background technology
Along with improving constantly of people's living standard, by the system that installs an air-conditioner, in order to promote the comfortableness of inhabitation and working environment, become the important selection that people improve the comfortableness demand under inhabitation and office work environment.Wherein, multi-online air-conditioning system due to have control free, energy-efficient, be convenient to the advantage such as installation and maintenance, be an important directions of central air-conditioning development.
Along with the air conditioning demand of growing air conditioning chamber's internal loading and volumed space building, the air handling capacity that is applied to the wind pipe type multi-online air-conditioning system in the large space buildings such as office building, market, factory building, station is had higher requirement.
Wherein, the wind pipe type multi-online air-conditioning system, mainly comprise off-premises station and wind pipe type indoor set; The air focused on through off-premises station, be delivered to respectively each wind pipe type indoor set by cooling medium liquid pipe or refrigerant tracheae, the processing such as the blower fan in the wind pipe type indoor set, heat exchanger, be delivered to the indoor of wind pipe type indoor set is installed, the air of processing and room air directly carry out warm and humid exchange, realize the adjusting to Temperature and Relative Humidity of Indoor Air.
Fig. 1 is existing wind pipe type indoor machine structure schematic diagram.Referring to Fig. 1, existing wind pipe type indoor set comprises: blower fan 01, motor 02, control panel 03, sensor 04, throttling arrangement 05, controller 06; Wherein,
Blower fan 01 is connected with motor 02; Control panel 03 is connected with motor 02, sensor 04, throttling arrangement 05 and controller 06 respectively.
The temperature information of receiving sensor 04 sensing output, determine running status and the operational mode of wind pipe type indoor set, by running state information and operational mode information output to controller 06.
Wherein, running state information shows that the wind pipe type indoor set is in normal operation, fault or the state such as abnormal.The technical staff obtains running state information and temperature information by host computer, can be controlled the load capacity of wind pipe type indoor set.
Rotation speed of fan control signal and the control signal of damming are meaned with load capacity dialing figure place.Be provided with a control panel in each wind pipe type indoor set, control panel, by the dial mode of figure place of load capacity, is controlled wind pipe type indoor set load capacity.For example; the situation that is 5 for wind pipe type indoor set load capacity; if the load capacity of design dialing figure place is 4; the a reference value of load capacity dialing figure place is 5/15; and shut down with 0000 expression; 0001 means that wind pipe type indoor set load capacity is 5/15, and 0010 means that wind pipe type indoor set load capacity is 10/15, so analogizes.For instance, if the load capacity information that control panel 03 receives is 3, after carrying out the number conversion of load capacity dailing bit, generating corresponding load capacity dialing information is 1001, thereby the rotation speed of fan control signal of generation can be expressed as 1001.Motor 02 receives the rotation speed of fan control signal, for example, after 1001, with a reference value of load capacity dialing figure place, combine, obtain wind pipe type indoor set load capacity information corresponding to rotation speed of fan control signal, the wind pipe type indoor set load capacity of inquiry storage and the mapping relations of rotation speed of fan, obtain rotation speed of fan corresponding to rotation speed of fan control signal, and drive blower fan 01 to rotate, the rotation speed of fan of wind pipe type indoor set is set on the rotation speed of fan obtained.
