Description

The method of wind pipe type indoor set and control wind pipe type indoor set capacity
Technical field
The present invention relates to multi-gang air-conditioner technical field, particularly relate 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 under inhabitation and office work environment, in order to promote the comfortableness of inhabitation and working environment, become the important selection that people improve comfortableness demand.Wherein, multi-online air-conditioning system due to have control free, energy-efficient, be convenient to the advantages such as installation and maintenance, be central air-conditioning development an important directions.
Along with the air conditioning requirements of growing air conditioning chamber's internal loading and volumed space building, the air handling capacity of the wind pipe type multi-online air-conditioning system be applied in the large space buildings such as office building, market, factory building, station is had higher requirement.
Wherein, wind pipe type multi-online air-conditioning system, mainly comprises off-premises station and wind pipe type indoor set; Through the air that off-premises station focused on, each wind pipe type indoor set is delivered to respectively by cooling medium liquid pipe or refrigerant tracheae, the process such as the blower fan in wind pipe type indoor set, heat exchanger, be delivered to the indoor of installing wind pipe type indoor set, the air processed and room air directly carry out warm and humid exchange, realize the adjustment to Temperature and Relative Humidity of Indoor Air.
Fig. 1 is existing wind pipe type indoor machine structure schematic diagram.See 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.
Controller 06, for receiving the load capacity information from outside host computer, exports control panel 03 to; Receive the running state information from control panel 03, export outside host computer to;
Control panel 03, corresponding rotation speed of fan control signal and control signal of damming is generated according to the load capacity information received, export the rotation speed of fan control signal of generation to motor 02, to make motor 02 arrange rotating speed and the power of blower fan 01 according to rotation speed of fan control signal, thus the static pressure of control inputs wind pipe type indoor set and air quantity; Export the control signal of damming generated to throttling arrangement 05, to make throttling arrangement 05 arrange the open degree of electric expansion valve on wind pipe type indoor-unit cooling-medium pipeline according to control signal of damming, thus control indoor temperature;
Receiving sensor 04 senses the temperature information exported, and determines running status and the operational mode of wind pipe type indoor set, exports running state information and operational mode information to controller 06.
Wherein, running state information shows that wind pipe type indoor set is in the states such as normal operation, fault or exception.Technical staff obtains running state information and temperature information by host computer, can control the load capacity of wind pipe type indoor set.
Rotation speed of fan control signal and control signal of damming represent with load capacity dialing figure place.Be provided with one piece of control panel in each wind pipe type indoor set, control panel, by the mode of load capacity dialing figure place, controls wind pipe type indoor set load capacity.Such as; for the situation that wind pipe type indoor set load capacity is 5; if the load capacity dialing figure place of design is 4; then a reference value of load capacity dialing figure place is 5/15; and represent shutdown with 0000; 0001 represents that wind pipe type indoor set load capacity is 5/15, and 0010 represents that wind pipe type indoor set load capacity is 10/15, so analogizes.For example, if the load capacity information that control panel 03 receives is 3, then after carrying out the number conversion of load capacity dailing bit, generating corresponding load capacity dialing information is 1001, and thus, the rotation speed of fan control signal of generation can be expressed as 1001.Motor 02 receives rotation speed of fan control signal, such as, after 1001, combine with the dial a reference value of figure place of load capacity, obtain the wind pipe type indoor set load capacity information that rotation speed of fan control signal is corresponding, the mapping relations of the wind pipe type indoor set load capacity that inquiry stores and rotation speed of fan, obtain the rotation speed of fan that rotation speed of fan control signal is corresponding, 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 of acquisition.
For the control signal of damming that throttling arrangement 05 receives, such as, 1001, the dial a reference value of figure place of the value that control signal of damming represents by throttling arrangement 05 and load capacity combines, obtain the wind pipe type indoor set load capacity information that control signal of damming is corresponding, the mapping relations of the wind pipe type indoor set load capacity that inquiry stores and electric expansion valve open degree, obtain the electric expansion valve open degree that control signal of damming is corresponding, the aperture of electric expansion valve is set according to the electric expansion valve open degree obtained.
At present, in order to effectively expand total load number that multi-online air-conditioning system can bear and reduce operating cost, when the wind pipe type indoor set number of units that can connect is comparatively limited, requirement suitably can increase the load capacity of separate unit wind pipe type indoor set.Because the load capacity of wind pipe type indoor set can realize by regulating the size of refrigerant pipeline, thus, under the prerequisite not changing wind pipe type indoor machine structure, can be easier to realize the upgrading to wind pipe type indoor set load capacity.But, because the figure place of the control panel load capacity dial-up of existing control wind pipe type indoor set load capacity limits, make the load capacity control signal exported can not meet the upgrade requirement of wind pipe type indoor set load capacity.Such as, for the situation that former wind pipe type indoor set load capacity is 5, by upgrading, its load capacity is 10, but motor is according to the rotation speed of fan control signal received, combine that the wind pipe type indoor set bearing load capacity that obtains is maximum can only be 5 with the dial a reference value of figure place of load capacity, thus maximum can be 5 by wind pipe type indoor set bearing load capacity setting, cause the upgrading load capacity that effectively can not utilize wind pipe type indoor set, carry out newly developed, the construction cycle will be made longer.
