Abstract
The invention discloses a novel humidity control air-conditioner. The humidity control air-conditioner can control the quantity demand more directly according to actual demands. One or more control modes are reserved in a humidity control module through programming. When one mode is reserved, conversion of different control demands is achieved by changing setting parameters. When multiple modes are reserved, conversion of different control demands is achieved by adopting mode selection. At least one mode adopts the humidity parameter which is completely independent as the major control object, and the humidity parameter which is completely independent can be the dew point temperature or the absolute humidity or the moisture content or any other temperature control objects which have the same function and are independent from the dry-bulb temperature. The relative humidity can be adopted as the minor control object, or minor control objects also can be abandoned.
Description
Technical field
The present invention relates to a kind of air-conditioning, more specifically, relate to a kind of air-conditioning with moisture control function.
Background technology
Usually, there is the air-conditioning of moisture control function, control humidification by the RH range of the relative humidity and permission that simply contrast actual measurement and dry the enabling of function.
Because relative humidity is often relevant to dry-bulb temperature, the position of humidity feedback transducer, measurement point, with the dry-bulb temperature of the fluctuation of load, all causes the inaccuracy of humid control.
And due to most of application scenario, the mixture of just absolute humidity or dew-point temperature or water capacity and relative humidity that actual needs controls, adopt single relative humidity as control object, often cause humid control to depart from demand or too much enabling humidification and dry function, increase humid control power consumption.
Summary of the invention
In order to overcome existing air-conditioning using relative humidity as the deficiency of control object, the invention provides a kind of new humid control air-conditioning, this humid control air-conditioning can more direct demand for control amount according to the actual requirements, cancel the position constraint of sensor, humid control scope is directly approached the scope needing to control, realize the full decoupled and independence of humidity and temperature completely.
The technical solution adopted for the present invention to solve the technical problems is: be programmed in one or more control models reserved in humidity control module by control program.During reserved a kind of pattern, by the change of setup parameter, realize the transformation of its different demand for control.Adopt model selection during reserved various modes, realize the transformation of its different demand for control.Wherein have at least a kind of pattern should comprise using completely independently humidity parameter as major control object, this completely independently humidity parameter can be dew-point temperature, any humid control object independent of dry-bulb temperature of absolute humidity or water capacity or other same functions.And relative humidity can be adopted as auxiliary control object, or do not adopt any auxiliary control object.
A scheme according to the present invention can realize following three kinds of conventional humid control patterns.
One adopts dew-point temperature to add relative humidity as control object; Its two employings dew-point temperature is as control object; Its three employings relative humidity is as control object.
Pattern one, by empirical equation or chart, the dry-bulb temperature come Temperature Humidity Sensor feedback and wet-bulb temperature calculate, or directly draw corresponding dew-point temperature and relative humidity according to dew point temperature sensor and relative temperature sensor, when dew-point temperature and relative humidity exceed set tolerance band time, carry out the adjustment of PID closed loop feedback according to the gap of itself and setting range value and control accuracy.
Pattern two, on the basis of pattern one, realizes by the setting range of relative humidity is set to 0-100%.
Pattern three, on the basis of pattern one, by being set to-300-1000 DEG C and realizing by the setting range of dew-point temperature.Can reduce according to the application scenarios of correspondence or expand its default value.
According to another aspect of the present invention, provide and a kind ofly add the air-conditioning of relative humidity as Comprehensive Control object using absolute humidity or water capacity.
According to air-conditioning of the present invention, there is following one or more effect.
The first, due to the humidity adopting the humid control object independent of dry-bulb temperature to control controlled air, achieve the full decoupled of Temperature and Humidity Control.Offer convenience to air-conditioning system and application design.
The second, because humiture is full decoupled with independence, can the humid control demand of more closing to reality, expand the allowed band of humidity, reduce unnecessary humidification and dry energy consumption.
3rd, because humiture is full decoupled with independence, does not affect its setting demand and value of feedback in different positions, relieve the position constraint to humid control sensor.
4th, owing to switching different humid control patterns by setting parameter or model selection, adapt to diversified humid control demand.
Detailed description of the invention
Below, Multi-instance of the present invention will be described.But the spirit and scope that the present invention proposes are not restricted to these embodiments that this description proposes.Those skilled in the art well can understand other examples be in the spirit and scope of the present invention.
According to one embodiment of present invention, being the sensor by typical case being had in the air-conditioning of moisture control function, being replaced by Temperature Humidity Sensor.Control system through programming input empirical equation, increases the main humid control program of a set of PID closed loop in former control logic.Control and feedback element using the dew-point temperature of rule of thumb formula and dry-bulb temperature and relative humidity calculation as control object.Simultaneously using original relative humidity control program as auxiliary humid control program.Major-minor calculation procedure will select a calculation procedure to make its also output feedack that comes into force to humidification and executing agency of drying, form closed-loop control according to setting automatically.
According to another embodiment of the invention, being the sensor by typical case being had in the air-conditioning of moisture control function, being replaced by Temperature Humidity Sensor.Former relative humidity pa through programming input empirical equation, is replaced by the absolute humidity calculated through empirical equation by control system in former control logic.And run with former control logic.
Claims (2)
1. possess an air-conditioning for moisture control function, it is characterized in that: in the design of this air-conditioning humid control, have at least a kind of control logic to have employed using absolute humidity or water capacity or dew-point temperature as the strategy of main humid control object or method.
2. air-conditioning according to claim 1, it is characterized in that: have employed independently dew point temperature sensor or have employed empirical equation or chart has carried out COMPREHENSIVE CALCULATING to dry-bulb temperature and relative humidity in control system logic, and under partial condition, using this result of calculation as humid control object.
